Small Electrical Jobs

Small Electrical Jobs near you

Small electrical jobs are the ones people assume are too minor to involve anybody official: an extra socket in a bedroom, a spur for a desk, a replacement light switch, an outside light by the back door, a shaver socket, a new extractor fan. In England the question of whether any of that has to be notified to building control was settled in 2013 and the answer surprises people, because the list is much shorter than it used to be. In Wales it was not narrowed, which means an identical job can be notifiable in Cardiff and not notifiable in Bristol.

The English list is in regulation 12(6A) of the Building Regulations 2010 and reproduced in Approved Document P, the 2013 edition, which took effect on 6 April 2013 and is for use in England. Three things are notifiable: the installation of a new circuit, the replacement of a consumer unit, and any addition or alteration to existing circuits in a special location. Everything else is not notifiable - the approved document says so directly, listing additions and alterations outside special locations, and replacements, repairs and maintenance anywhere.

Not notifiable does not mean unregulated. All electrical installation work in a dwelling is still subject to requirement P1, and Approved Document P says installations should be designed and installed in accordance with BS 7671. The difference is only in who has to be told, and in what paperwork you are left holding at the end.

What is notifiable in England, and what a special location is

Regulation 12(6A) requires a building notice or full plans where the work consists of the installation of a new circuit, the replacement of a consumer unit, or any addition or alteration to existing circuits in a special location. The definition of special location is precise. It covers the space around a bath tap or shower head, extending vertically from finished floor level to 2.25 metres - or to the shower head where that is fixed higher - and horizontally 0.6 metres from the edge of a bath tub or shower tray, or, where there is no tub or tray, 1.2 metres from the centre point of a wall or ceiling mounted shower head. It also covers any room containing a swimming pool or a sauna heater.

Approved Document P then states the consequence plainly: all other electrical installation work is not notifiable, namely additions and alterations to existing installations outside special locations, and replacements, repairs and maintenance anywhere. It adds two worked examples that answer most household questions. Installing a built-in cooker is not notifiable unless a new cooker circuit is needed. Connecting an electric gate or garage door to an existing isolator is not notifiable, but installing a new circuit from the consumer unit to that isolator is.

One more note in the same document is worth knowing when planning a bathroom: socket-outlets should not be located within three metres of a bath tub or shower tray.

Wales, Scotland and Northern Ireland do not follow the English list

Wales did not adopt the 2013 narrowing. The Welsh Government's guidance on electrics describes minor, non-notifiable work as replacing any electrical fitting such as socket outlets, light fittings and control switches; adding a fused spur to an existing circuit but not in a kitchen, bathroom or outdoors; repair and maintenance work; installing or upgrading main or supplementary equipotential bonding; and installing extra-low voltage cabling for signalling or communication. In other words, adding a socket in a Welsh kitchen or running a light into a Welsh garden is notifiable where the same job in England would not be. That is the single most useful devolution fact on this page.

Scotland does not use Part P at all. Building standards there are set under the Building (Scotland) Regulations, with standard 4.5 requiring that electrical installations do not threaten the health and safety of people in and around the building or become a source of fire, and the technical handbook pointing at BS 7671. The control mechanism is the building warrant granted by the local authority verifier, and the handbook notes that an approved certifier of construction who has been assessed as having the professional skills and relevant experience can certify compliance of an electrical installation. Whether a particular job needs a warrant depends on the work and the building, so ask your local authority.

Northern Ireland has its own Building Regulations (Northern Ireland) 2012 and its own technical booklets. It also has a separate, newer regime for rented homes: the Electrical Safety Standards for Private Tenancies Regulations (Northern Ireland) 2024 came into operation on 1 April 2025, require inspection and testing by a qualified person at intervals of no more than five years against the eighteenth edition of the Wiring Regulations, and set 1 December 2025 as the deadline for first inspections of existing tenancies.

The three routes to certifying notifiable work

Approved Document P sets out three procedures, and only three. The first is self-certification by a registered competent person: the installer completes a BS 7671 electrical installation certificate for the job and gives it to whoever ordered the work, and the installer or their registration body must, within 30 days of completion, give a copy of the Building Regulations compliance certificate to the occupier and the certificate or its information to the building control body.

The second was introduced in 2013 for installers who are not registered. Before work begins they may appoint a registered third-party certifier to inspect and test as necessary; within five days of finishing, the installer must notify that certifier, who, if the results are satisfactory, completes an electrical installation condition report for the person who ordered the work, with the registration body issuing the compliance certificate within 30 days.

The third is to notify a building control body before work starts. The building control body then decides how much inspection and testing it needs, may do it itself or contract a specialist, and will take an installer's own BS 7671 certificate and qualifications into account. Local authority charges must take account of how much inspection work the authority expects to carry out, so a well-documented job can cost less to certify this way than a poorly documented one.

BS 7671, and which edition your installer should be working to

  • BS 7671 is the national standard for electrical installations in the United Kingdom, published jointly by the IET and BSI and known as the IET Wiring Regulations.
  • The current series is the 18th Edition, BS 7671:2018, as amended - Amendment 2:2022, Amendment 3:2024 published on 31 July 2024, and Amendment 4:2026.
  • BS 7671:2018+A4:2026 supersedes the earlier amended version, which is withdrawn on 15 October 2026, with a transition period before that date.
  • HSE regards installations complying with BS 7671 as likely to achieve conformity with the relevant parts of the Electricity at Work Regulations 1989.
  • Approved Document P's own technical guidance still refers to an older amendment of BS 7671, but the approved documents allow a revised version of a listed standard to be used as guidance where it continues to address the relevant requirements.
  • Northern Ireland's private tenancy regulations name the eighteenth edition explicitly, which is a useful reminder that the standard is referenced across the UK even where building control differs.

Which small jobs fall which side of the line in England

  • Replacing a socket front, a light switch or a light fitting on an existing circuit outside a special location: not notifiable, but it must still meet BS 7671.
  • Adding a socket or a fused spur to an existing circuit in a living room, bedroom or hall: not notifiable in England, but notifiable in a Welsh kitchen or bathroom.
  • Any addition or alteration to circuits inside the zones around a bath or shower: notifiable.
  • Replacing the consumer unit, whatever the reason: notifiable.
  • Running a new circuit for a cooker, a shower, an outbuilding or a car charger: notifiable, because it is a new circuit.
  • Connecting fixed equipment to an existing isolator, such as an electric gate: not notifiable; installing the circuit that feeds that isolator is.
  • Installing prefabricated modular wiring, such as a plug-and-socket kitchen lighting system: within the scope of Part P, notifiable only if it involves the work in regulation 12(6A).

Why the paperwork is the safety feature

Approved Document P says electrical work should be inspected and tested in accordance with the procedures in BS 7671 to verify that the design and installation are adequate and that the installation will be safe to use, maintain and alter, and that the test forms should be given to the person ordering the work. That sentence is the reason to care about certificates on a job as small as a spur: the certificate is the record that someone measured the earth fault loop impedance and proved the protective device will operate, rather than simply making the light come on.

It also matters when the house changes hands or is let. Building Regulations certificates normally go to the occupier, and in rented property may go to the person ordering the work with a copy to the occupier. Landlords in England have a separate duty under the Electrical Safety Standards in the Private Rented Sector (England) Regulations 2020 to have every electrical installation inspected and tested by a qualified person at intervals of no more than five years, or sooner where the report says so, and to obtain a report giving the results and the date of the next inspection.

For a homeowner doing nothing more than adding a socket, the practical test of a good electrician is whether they talk about testing and certification without being asked, and whether they can tell you which of the three certification routes applies if the job turns out to be notifiable.

What drives a small electrical quote, and how LokalMatch fits in

Small electrical work is priced on access and certification as much as on the fitting. The variables are how far the new point is from a suitable existing circuit, whether cables can be run in a void or must be chased into masonry and made good, what the wall and floor construction allows, whether the existing installation is in a condition to take the addition, whether the job falls inside the notifiable list where you live, and whether making good and decorating are included. Testing and certification are a fixed part of doing it properly and should appear in the quotation rather than as an extra.

LokalMatch is the introduction and nothing more. Set out what you want, where it is in the house and what is already nearby, add your postcode, and electricians covering your area get in touch with you directly. Homeowners are not charged for this; the businesses pay for the requests they receive. LokalMatch does not do electrical work, does not set prices and does not vet, rank or recommend anyone, so checking scheme registration and asking which certificates you will receive is your part of the job.

Small Electrical Jobs: frequently asked questions

Which electrical work has to be notified in England?

Three things, under regulation 12(6A) of the Building Regulations 2010: installing a new circuit, replacing a consumer unit, and any addition or alteration to existing circuits in a special location. A special location means the space around a bath tap or shower head - up to 2.25 metres high, 0.6 metres from a bath or shower tray, or 1.2 metres from a wall or ceiling mounted shower head where there is no tray - and any room containing a swimming pool or sauna heater. Approved Document P states that all other electrical installation work is not notifiable.

Is the rule the same in Wales?

No, and this catches people out. Welsh Government guidance lists minor non-notifiable work as replacing fittings such as sockets, light fittings and switches; adding a fused spur to an existing circuit but not in a kitchen, bathroom or outdoors; repair and maintenance; installing or upgrading equipotential bonding; and extra-low voltage signalling or communication cabling. So adding a socket in a kitchen, or a light outdoors, is notifiable in Wales when the same work in England would not be.

What happens in Scotland and Northern Ireland?

Scotland does not use Part P. Building standards there are enforced through building warrants granted by local authority verifiers, standard 4.5 covers electrical safety and the technical handbook points to BS 7671, and an approved certifier of construction with the assessed skills and experience can certify an electrical installation. Northern Ireland has its own Building Regulations (Northern Ireland) 2012 and technical booklets, plus the Electrical Safety Standards for Private Tenancies Regulations (Northern Ireland) 2024, which came into operation on 1 April 2025 for rented homes.

Can an unregistered electrician do notifiable work legally?

Yes, by one of two routes. Before work begins they can appoint a registered third-party certifier to inspect and test, notify that certifier within five days of completing the work and have a condition report issued, with the registration body sending the compliance certificate within 30 days. Alternatively they must notify a building control body before starting, and the building control body decides what inspection and testing it needs. What they cannot do is simply carry out notifiable work and tell nobody.

What certificates should I end up with?

For notifiable work done by a registered competent person, a BS 7671 electrical installation certificate for the job, plus a Building Regulations compliance certificate: the installer or their registration body must give you a copy within 30 days of completion and pass the certificate or its information to building control. For non-notifiable work there may be no Building Regulations certificate at all, but you should still receive the BS 7671 test results, because they are the record that the work was verified rather than simply connected.

Which edition of the Wiring Regulations should the work meet?

The current BS 7671. The 18th Edition, BS 7671:2018, has been amended several times - Amendment 2:2022, Amendment 3:2024 published on 31 July 2024 and Amendment 4:2026 - and BS 7671:2018+A4:2026 supersedes the earlier version, which is withdrawn on 15 October 2026. Approved Document P still names an older amendment in its technical guidance, but the approved documents permit a revised version of a listed standard to be used where it continues to address the relevant requirements.

What affects the cost of small electrical

Prices depend on the details of your project. We only publish price ranges when they’re backed by real LokalMatch quote data or reliable sources. Until then, here’s what usually changes the price:

  • Number and type of tasks
  • Time needed and any minimum visit charge
  • Materials and parts
  • Wall type and what's being mounted or hung
  • Height and access

How to compare electricians before you hire

  • Describe all the small jobs up front so the handyman can bring the right tools and give you a realistic estimate.
  • Ask whether they charge by the hour, by the job or with a minimum visit fee.
  • For anything involving wiring, gas or new plumbing, use a licensed trade instead of a general handyman.
  • Check that they carry liability insurance, especially for work on ladders or on the exterior.
  • Ask whether they supply materials or whether you should buy them ahead of time.

Questions to ask electricians before you hire

  • Do you charge by the hour or by the job, and is there a minimum?
  • Can you do all of the jobs on my list, or will some need a licensed trade?
  • Will you bring the materials, or should I buy them?
  • Are you insured if something is damaged while you're working?
  • How do you handle it if a job takes longer than expected?

Small electrical permits and local rules

Some small electrical work needs a permit or has to meet local bylaws. Rules vary by municipality, so ask your pro whether a permit is needed and who will apply for it — and check with your city or town if you’re unsure.
