Who may do what: reserved work, and the argument about licensing

Adding a socket to a kitchen circuit needs no notice in England. Do the same job over the border in Wales, and it's notifiable: a registered electrician certifies it, or, for your own work, building control must be told before you start. In New York City it needs a licensed electrical contractor, whoever owns the house. What changes is the answer to the course's question: law or advice, whose, and where? That question is this lesson's first half. The second is an argument about whether licensing tradespeople makes their work safer.

This is general information, not legal advice. The rules differ between England, Wales, Scotland and Northern Ireland, and between US states and cities, and they change. Nothing here says what you may lawfully do in your own case; it says which rule applies where, and whom to ask.

Two questions, never one

This is general information, not legal advice.

People ask "am I allowed to do this?" as if it were one question. The law in England, Wales and Scotland asks two, and they have different answers:

1. Must the work comply? Does it have to meet a legal standard, whoever does it?
2. Must someone be told? Does building control, or a registered scheme, have to know and check?

A job can need no notice at all and still have to meet the standard.

England

This is general information, not legal advice.

Every piece of electrical work in an English home must meet requirement P1, in Part P (the electrical safety part) of Schedule 1 to the Building Regulations 2010: "Reasonable provision shall be made in the design and installation of electrical installations in order to protect persons operating, maintaining or altering the installations from fire or injury."⁴

Only three kinds of work have to be notified. Regulation 12(6A) lists them: "the installation of a new circuit", "the replacement of a consumer unit", and "any addition or alteration to existing circuits in a special location".¹ A special location is the space around a bath or shower. It runs up to 2.25 metres from the floor, or to the shower head if that's higher, and 0.6 metres out from the edge of the bath or tray. Where there's no tray, it's 1.2 metres from the centre of the shower head. A room with a swimming pool or a sauna heater is one too. A kitchen is not. England narrowed the list to these three on 6 April 2013.¹⁵

Approved Document P, the government's guidance for England, says "All other electrical installation work is not notifiable", and answers the first question for it too: "Non-notifiable electrical installation work, like notifiable work, should be designed and installed, and inspected, tested and certificated in accordance with BS 7671." BS 7671 is the national wiring standard.⁵

Notifiable work has three routes: self-certification by a registered competent person, a registered third-party certifier appointed before the work begins, or a building control body (your council's building control is one).⁵ The last is the householder's: "If an installer is not a registered competent person and has not appointed a registered third-party certifier, then before work begins the installer must notify a building control body."⁵

Why tell anyone? So that someone checks: building control inspects and issues a completion certificate, and a scheme inspects its members' work instead.⁵³⁴ Regulation 20 gives a scheme member 30 days after completion to give the occupier a certificate and notify the council (GOV.UK's guide says you'll get one within 8 weeks), and the certificate is "evidence (but not conclusive evidence)" that the work complies.⁴⁶ GOV.UK's list of schemes, updated 17 September 2026 and read on 26 September, names five for electrical work in homes, among them "Certsure LLP trading as NICEIC" and "NAPIT Registration Limited".⁷ Lesson 23 shows how to check membership. If you rent, lesson 6, "Plugs, leads and electrical fires", gave a landlord's electrical inspection duty in England, and any work here is a question for your landlord first.

Wales

This is general information, not legal advice.

Wales shares the 2010 Regulations but kept the older, longer list when England cut its own. The Welsh government's guidance says you need not tell building control about "repairs, replacements and maintenance work or extra power points or lighting points or other alterations to existing circuits (except in a kitchen or bathroom, or outdoors)".⁸ The Welsh Schedule 4 frees replacements and repairs from notice anywhere, but frees added lights, switches, sockets and fused spurs on an existing circuit only if the work "is not in a kitchen, or a special location" and involves no special installation, such as outdoor lighting or power.² The Welsh approved document adds that "Consumer unit replacements are, however, notifiable."³⁵ Work by a registered installer needs no notice before it starts: regulation 20 has the installer notify within 30 days after.⁴ The householder's route is to tell building control before starting, "if you do the work yourself"; and "If you do the work yourself you may wish to engage a qualified electrician to check it for you."⁸

Scotland

This is general information, not legal advice.

Scotland uses building warrants, under its own Building (Scotland) Regulations 2004. Regulation 5 says work listed in Schedule 3 must still meet the building standards but needs no warrant.⁹ Exempt from a warrant is not exempt from the standards: the two questions again.

Schedule 3's first entry is "Any work to or in a house", with exceptions such as extending the floor area, altering the structure, or harming a separating wall.⁹¹⁰ "House" means "a dwelling on one or more storeys, either detached or forming part of a building from all other parts of which it is divided only vertically", so a flat is not one.⁹ The technical handbook (the 2022 edition; check gov.scot for a later one) says the exemptions "permit virtually any work to be carried out to 1 or 2 storey houses", electrical work included.¹⁰

Standard 4.5 applies either way: an installation must not "become a source of fire".¹⁰ For flats, a research appendix the Scottish Government published in 2019 says that for rewiring "a building warrant is required for flats and buildings over three storeys, while houses up to two storeys are exempt".¹¹ And the IET says "Part P electrical self-certification schemes in England & Wales do not apply to work in Scotland."¹²

Northern Ireland

This is general information, not legal advice.

Northern Ireland's Building Regulations (Northern Ireland) 2012 have a Part P, but it covers "Sanitary appliances, unvented hot water storage systems and reducing the risk of scalding", and no Part covers electrical safety.¹³ Electrical Safety First (ESF), a UK charity that campaigns on electrical safety, says: "There are currently no statutory requirements for domestic electrical installation work in Northern Ireland." It "strongly recommends that you engage a competent registered electrician".¹³ That's advice, from a charity.

One job, four nations

Hold one job still: adding a socket to an existing kitchen circuit, in a house, not a flat. This is only about which rule applies.

On the law, the job is Yours, on conditions in England, Wales and Scotland (meet the standard; in Wales, notify through a scheme member or, doing it yourself, building control first), and in Northern Ireland, on ESF's account, no statutory rule applies. On ESF's advice and this course's scope, it's Call someone in all four.

Other notifiable work, briefly

This is general information, not legal advice.

In England and Wales, Schedule 3 lets registered installers self-certify other work too, among it a heat-producing gas appliance (by a member of the Gas Safe class), heating systems, and replacement windows and doors.³ And "Building regulations approval is different from planning permission. You might need both."⁶ Who may do gas work at all is lesson 10's, "Gas: the law and the engineer": in Great Britain, registration binds those who do gas work as a business and competence binds everyone, and HSE and the Register advise a Gas Safe registered engineer, so the label is Call someone.²¹²²²³

When work doesn't comply, and when you sell

This is general information, not legal advice.

In England and Wales, section 35 of the Building Act 1984 says: "A person who contravenes a provision of building regulations, or a requirement imposed by virtue of any such provision, commits an offence." On indictment the penalty can be up to two years in prison or a fine. That wording has applied in England since 2023, and in Wales in full since 1 July 2026.¹⁴

Section 36 lets the council require the owner to remove or alter work that contravenes the regulations. If the owner doesn't act within 28 days, the council can do the work and recover the cost. The limit for giving that notice is now "10 years" from completion, in England since 1 October 2023 and in Wales since 1 July 2026. This course did not read how the change applies to work finished before it took effect.¹⁴

There's a way back. Under regulation 18, the owner of unauthorised work done on or after 11 November 1985 can apply for a regularisation certificate, and the council may have the work opened up and tested.⁴

Selling is where most people meet this. The Law Society's notes on its property information form say "From 1 January 2005, all electrical installation work must follow building regulations", and that most electrical work needs a building control completion certificate, the installer's compliance certificate or an installation certificate, which the seller attaches to the form. The same notes say an electrical installation condition report (the EICR of lesson 5) "is not a legal requirement for the sale of property in England and Wales."¹⁵ This course did not read Scotland's or Northern Ireland's enforcement rules.

The US: the shape, then five places

This is general information, not legal advice.

Notice the change in kind. In England, registration is a way of telling building control, not a permission to work: an installer who is not registered notifies building control instead. In the US places read, a licence decides who may do the work at all, and an owner's exemption is the way round it.

This course found no national US rule on who may do electrical or plumbing work in a home. Licensing is state law in four of the five places read; New York City sets its own. Permits and inspections are usually run by a city or county building department (for electrical work in Washington, the state, unless the city inspects its own), under the model codes that states adopt. And four of the five places read have homeowner exemptions from licensing: real, but conditional, on your own home, your own hands, a permit, and a rule about selling. They cannot tell you the rule anywhere else.

California. Section 7044 of the Business and Professions Code says the licensing chapter doesn't apply to "An owner who builds or improves a structure on his or her property". The conditions: none of it is for sale, and the owner does the work personally or with wage-paid employees. A sale within a year of completion raises a rebuttable presumption that it was for sale.¹⁶

Texas. The state licensing department, TDLR, says electrical work on "a dwelling by a person who owns and resides in the dwelling" is not required by the state to be licensed, and adds: "Municipal or regional regulations may override these exemptions".¹⁷ This course read TDLR's account, not the statute's official text.

Florida. Section 489.503(6) exempts "An owner of property making application for permit, supervising, and doing the work" on their own single-family or duplex home, "not intended for sale", and the owner "shall personally appear and sign the building permit application". Selling, or offering for sale, more than one such structure within a year of completion is "prima facie evidence" that the work was for sale. The permit office must give the owner a disclosure statement, which begins: "State law requires electrical contracting to be done by licensed electrical contractors." It adds: "You may not hire an unlicensed person as your electrical contractor."¹⁸

Washington. RCW 19.28.261 says no licence is needed for electrical work at your own residence unless it's on a new building for rent, sale or lease, or "The electrical work is on property that is offered for sale within 12 months after obtaining the property."¹⁹ It is not a free pass. The state's form begins: "In Washington, only licensed electrical contractors employing certified electricians may perform electrical work." The owner applies for an exemption, signs an affidavit before starting, and gets a permit and an inspection.¹⁹

New York City. The Department of Buildings says electrical work "shall be performed by a New York City licensed electrical contractor", and that plumbing and gas repairs needing no permit still "must be performed by a Licensed Master Plumber."²⁰

A garage workshop circuit in three places

Three owners, none of them selling, each want a new circuit run to a detached garage for a workshop. In England this would be notifiable. On the law:

• In Washington, no licence, but the property owner permit: the application and affidavit before starting, then the inspection. Yours, on conditions.¹⁹
• In Florida, the owner may act as their own electrical contractor, applying for and signing the permit in person, for a home not intended for sale. Yours, on conditions.¹⁸
• In New York City, a licensed electrical contractor and an electrical permit. Call someone, and here the law says so.²⁰

On this course's scope, the label for all three is Call someone: a page can't check the work (see "Why this course teaches no wiring").

Why this course teaches no wiring

This is general information, not legal advice.

Lesson 5, "Electricity: what trips, and why", drew this course's line at the front of the consumer unit, and it holds here: where the law lets a householder do electrical work, the course still teaches none of it. The reason is what a page can do. Proving a circuit dead takes proper test equipment and the training to use it, as HSE's guidance for electrical workers describes, and HSE doesn't recommend "non-contact devices such as 'volt sticks'".²⁵ A panel is "usually electrically live, even with the main circuit breakers turned off" (CPSC).²⁴ A page can't watch you or check the result.

That's a teaching judgement. It is not a claim that the work is unlawful where the law allows it, and it is not a side in either argument that follows.

Does licensing make work safer?

Everything so far is established fact: the rules say what they say. This half has two questions serious people disagree about. One is contested and empirical: does licensing tradespeople improve the quality and safety of their work, and at what cost? The other is a value question: should householders be allowed to do their own electrical work? The course answers neither. It gives each side in its own words, and the evidence it read. Logic and Argument lesson 7, "Reconstruction and charity: the strongest version first", is the rule for reading both. The question is live in Britain too: as the Scottish Government's 2020 consultation put it, "Currently anyone can call themselves an electrician, without the need for any qualifications or competency."³³

The evidence this course read

The fullest source is a 2015 US government report, Occupational Licensing: A Framework for Policymakers, by the Treasury's Office of Economic Policy, the Council of Economic Advisers and the Department of Labor. Its research appendix says: "Overall, the empirical research does not find large improvements in quality or health and safety from more stringent licensing. In fact, in only two out of the 12 studies was greater licensing associated with quality improvements."²⁷ On electricians, it reports one study finding that stricter requirements "did not significantly affect the severity of injuries suffered among electricians", which is the workers' own safety, not their customers'. In its section on jobs, not quality, it reports another finding that requiring an oral examination or experience was "associated with fewer per capita electricians."²⁷ It also reports that "Other research suggests that licensing is not always adequate to address quality concerns, but may be complementary with other forms of regulation": a study of television repairs found less fraud where licensing came with a state agency investigating complaints.²⁷

The report is not simply against licensing, and it's wrong to cite it as if it were. It says: "When designed and implemented carefully, licensing can offer important health and safety protections to consumers, as well as benefits to workers." Its first recommended practice is "Limiting licensing requirements to those that address legitimate public health and safety concerns". And it says it is "beyond the scope of this report to recommend reforms to State or other regulations for specific occupations."²⁷

The fire figures do not settle it either. Lesson 6 gave NFPA's average of 32,620 US home fires a year in 2015 to 2019 involving electrical distribution and lighting equipment; it counts the equipment, not who installed or last worked on it.²⁸ And ESF's survey of 1,000 electricians found "More than 30% had reports of electric shocks caused by incompetent DIY-ers"; it measures what electricians reported.²⁶ Neither compares licensed with unlicensed work.

The case for licensing and registration, in its proponents' own words

SELECT, which calls itself "Scotland's Electrical Trade Association", campaigns for statutory regulation of electricians. Its case starts from a gap in the law: "At present, lack of regulation means anyone can claim to be an electrician and carry out electrical work in Scotland. These unqualified individuals put the people of Scotland at risk of injury and death, through faulty electrical installation and maintenance work." It asks for protection of the title, not a licence for every job: "We want to make it an offence for someone to call themselves an electrician when they have no, or inadequate, qualifications. But above all, we want to see improved safety for both domestic and commercial consumers across Scotland."³¹ SELECT puts a figure on the harm: a report it commissioned "estimated that the “human cost” of faulty electrical work is around £120 million per year", and its 2018 statement says "10 people were killed and more than 600 injured in electrical fault-related incidents in 2016 alone".³¹ As quoted, neither figure says how much of the harm came from unqualified work.

The Utah Plumbing & Heating Contractors Association made the case in the US in June 2026, against what it calls "continuous efforts by lawmakers and influential groups to reduce or eliminate licensing requirements in Utah". Bad work hides: "When plumbing is done wrong, the problems do not always show up immediately." A licence tells the customer what they can't find out alone: "Licensing creates a standard. It tells homeowners, business owners, facility managers, builders, and government agencies that plumbing work should be handled by trained professionals who understand the code and carry responsibility for the work."³²

Both answer the objection their opponents raise, that a trade body gains when entry to its trade is limited. The Utah association says "Advocating for the industry is the bedrock purpose of this organization", and then: "This is not about protecting territory for the sake of protecting territory. It is about protecting public safety, maintaining code compliance, and making sure plumbing work is performed by people who are trained and licensed to do it."³² SELECT's then managing director, on who might be shut out: "We do not want to leave people behind if they want to operate as competent and safe electricians and we have taken steps to ensure that there are a variety of ‘routes to qualification’ to make the profession as inclusive as possible."³¹

The two make different asks. SELECT wants the title protected, not a licence to do the work; the Utah association argues for licensing proper, for plumbers. No source this course read argues, in its own words, for licensing electricians as such.

The case against licensing, or for less of it, in its proponents' own words

The US Federal Trade Commission gave its view to Congress in September 2017, from the perspective of competition. It grants that "Licensing can protect consumers from actual health and safety risks and support other valuable public policy goals", then: "But that does not mean all licensing is warranted, or that restrictions on an occupation always yield more benefits than harms. Licensing restrictions may impede competition and hamper entry into professional and services markets, yet offer few, if any, significant consumer benefits. Such regulations may lead to higher prices, lower quality, and reduced consumer access to services and goods."²⁹ Its first test for any licence: "Are there significant and non-speculative consumer health and safety issues, or other legitimate public policy purposes, that warrant licensing?" And where "it seems likely that anticompetitive effects will outweigh any consumer benefits", it says "the proponents of any restrictions should bear the burden of justifying why they are needed."²⁹

The Institute for Justice, which says it believes "all people have the right to earn an honest living in the occupation of their choice without arbitrary, unnecessary, or protectionist government interference" and "files cutting-edge constitutional cases in state and federal courts", made its case in License to Work, now in a third edition (2022). It counted "more than 2,700 licenses across the 50 states and the District of Columbia" among 102 lower-income occupations, needing on average "nearly a year of required education and experience, at least one exam, and $295 in fees".³⁰ It adds the cost to the customer: "one of the most consistent findings in licensing research is that by limiting entry, and thus competition, licensing leads to higher earnings for licensees", and "consumers pay the price for those higher earnings through higher costs, limited access to services or both."³⁰ As quoted, it gives no figure for how much prices rise in any one trade.

Both concede ground. The FTC says licensing "can serve important goals and, when used appropriately, protect consumers from harm", and warns in turn about "self-interested boards whose members represent the very occupation to be regulated."²⁹ The Institute reports evidence against its own general case: "there is evidence that early 20th-century licensing of midwives reduced maternal and infant mortality".³⁰ Neither proposes nothing in licensing's place: the Institute asks states to "favor less restrictive alternatives like inspections, registration and certification", and the FTC names "government registration or certification".³⁰²⁹

Weighing one claim from each side

Take one claim from each case and ask the same three things: what kind of claim is it, what does it rest on, and what would test it? Start with the Utah association's "When plumbing is done wrong, the problems do not always show up immediately." It's a claim about what a customer can see, and it rests on how plumbing fails, as the association describes it, not on a comparison. It supports some check before work is covered up, but does not choose between a licence and the alternatives the other side names. What would test it is whether hidden faults turn up less often where the trade is licensed than where it isn't, other differences controlled for. This course read no such study for plumbing.

Where they meet, and what would settle it

Both cases accept licensing where there's a real health and safety risk, and so does the federal report; the case for adds that the risk is often one the customer can't judge. They disagree about how often that's true of a given trade, what counts as evidence, and who should have to prove it.

Each side has a stake, and says so: the Utah association that advocating for its industry is its purpose, the Institute for Justice that it goes to court for the right to work free of what it calls protectionist interference. Logic and Argument lesson 8, "Fallacies: the names, the patterns, and why the experts warn you about the names", covers this: an interest is a reason to check the evidence harder, not to call the claim false. That applies to both sides equally.

What would settle it is comparisons of injury, fire or failure rates between places with different licensing rules for the same trade, other differences controlled for, or harm counts that separate qualified from unqualified work. Nothing this course read does either for electrical work in homes. The course stops there.

Should householders do their own electrical work?

This is general information, not legal advice.

This is a value question, and the places read answer it differently in law: England, Wales, Scotland (for houses; rewiring a flat needs a warrant), Washington and Florida allow it, on conditions. California's licensing law and, on TDLR's account, Texas's don't require a licence for an owner's own home. New York City requires a licensed electrical contractor.

ESF's position: "Although there are some jobs people can do themselves, be aware of any potential electrical risks before starting DIY", and "Any electrical work should be left to competent professionals."²⁶ When England cut its notifiable list in 2013, the government's reason was cost: it amended the rules "in order to reduce cost (whilst maintaining an appropriate electrical safety regime)". It recorded that "Revocation of Part P was not supported by respondents". Of 158 responses, a quarter came from electrical installation firms, a fifth from council building control and 11% from homeowners; 11% backed revocation, 11% no change and 62% the amendment. Its reason for keeping a regime at all was a possible market failure: "Market failure potentially arises due to information asymmetry as homeowners do not have the expertise to assess whether an electrical installation has been done competently".³⁴

The case for a householder's freedom to work on their own home is one this course did not find argued in its own words. The government's assessment says many homeowners who responded did so as DIYers, some with electrical qualifications, but does not give their reasons.³⁴ So the lesson won't put words in their mouths, and it reaches no verdict on this question or on licensing.

What people get wrong

"Part P means you can't do any electrical work yourself." England and Wales both give a householder a route: notify building control before starting. Most work is not notifiable at all.

"If it doesn't need notifying, no rules apply." P1 still applies (see "Two questions, never one").

"Part P applies in Northern Ireland." Its Part P is sanitary appliances and hot water (see "Northern Ireland").

"An electrician registered in England can certify work in Scotland." England's schemes don't apply there (see "Scotland").

"Once the work's been in a while, the council can't act." The limit for a section 36 notice is now 10 years (see "When work doesn't comply").

"The research shows licensing makes work safer." The federal report found little quality or safety gain in most studies it reviewed.

"The research shows licensing only protects the trade." The same report says careful licensing "can offer important health and safety protections", the FTC accepts that some licences are justified, and the Institute for Justice reports evidence that one, of midwives, reduced deaths.

Practice

For your plan

This lesson adds to the stop list: every job your state or city reserves to a licensed trade, and every job your nation requires notice for that you'd otherwise have done without telling anyone, each with the rule behind it, law or advice, whose and where. It adds to the call list: your building control body or building department, your state's licensing board in the US, and the GOV.UK list of competent person schemes in England.
