Unqualified Electrical Work: How to Bring It Up to Standard

It is a common story. You have a new kitchen fitted, the kitchen company runs the wiring for the sockets, the appliances, and the under-cabinet lights, and the job looks great. Then, sometimes years later when you come to sell, a solicitor asks for the electrical certificate, and there isn’t one. The kitchen fitter was not a qualified electrician, and nobody tested or certified the work.

This happens with kitchen fitters, bathroom fitters, general builders, and handymen. The work is often perfectly tidy to look at. The problem is that nobody competent has confirmed it is actually safe, and there is no paperwork to show it meets the wiring regulations.

Why an electrician cannot just sign it off

The instinctive fix is to get a qualified electrician to “certify” the existing work. It does not work like that, and it is worth understanding why, because it is the single most misunderstood point in this whole area.

An Electrical Installation Certificate is a declaration that the person signing it designed, installed, inspected, and tested the work to BS 7671. An electrician who did not do the work cannot honestly make that declaration. The certificate carries their name and their liability, for work they never saw being done and cannot vouch for inside the walls.

This is not just professional caution, it is the structure of the system. The certification body NAPIT states it directly: electrical certifiers “are not permitted to certify work retrospectively”. The third party certification route that exists under the Building Regulations requires the certifier to be appointed before the work starts, so they can inspect it at each stage. Once the work is done and buried, that route is closed.

Which certificate should you have

Part of the confusion is that people talk about “the electrical certificate” as if there is one document. There are several, and they do different jobs.

The EICR is the only one of these that a qualified electrician can produce for work someone else carried out. It reports; it does not certify.

What a qualified electrician can actually do

For work that has already been done by someone else, the useful document is an Electrical Installation Condition Report, an EICR. This is an inspection and test of the existing installation that reports on its condition. It does not certify the original work, because nobody can do that after the fact, but it tells you the thing you actually care about: is it safe?

An EICR records every observation with a code. C1 means danger is present. C2 means potentially dangerous. C3 means improvement recommended. A report with a C1 or C2 comes back Unsatisfactory, and those are the items that need putting right. For the fuller detail on what these mean and what an EICR costs, see our EICR cost guide.

How Nulectrics handles it

Our approach is straightforward, and it follows the rules above rather than working around them.

1. We inspect and test the installation and issue you an EICR. That is a report on what is there, whoever installed it.
2. We tell you plainly what is safe, what is not, and what the wiring regulations would expect.
3. We estimate for any remedial work needed to bring it up to standard.
4. Any remedial work we carry out, we certify, because we designed, installed, and tested it. The same applies to any other qualified firm you use for the remedial work.
5. Work we did not carry out stays on the report. We will not certify someone else’s installation, and you should be wary of anyone who offers to.

The end result is that you hold an honest picture of the installation, certificates for the parts that were properly redone, and a clear record for a buyer, a solicitor, or an insurer.

Was the work even notifiable?

Before assuming the worst, it is worth establishing whether the work needed notifying to Building Control at all, because a lot of the panic around missing certificates concerns work that never required notification.

In England, since 6 April 2013, only three types of domestic electrical work are notifiable: installing a new circuit, replacing a consumer unit, and any work in a special location (the zone around a bath or shower, or a room with a pool or sauna). Kitchens are not a special location and have not been since 2013. So a kitchen fitter adding sockets and lights to existing circuits was doing non-notifiable work. If they ran a new circuit back to the consumer unit, or changed the board, that part was notifiable.

There is a catch that matters. Non-notifiable does not mean the rules do not apply. Approved Document P is explicit: all electrical work in a home must still meet BS 7671, whether it needed notifying or not. So the kitchen fitter’s work still had to be safe and compliant. It just may not have needed Building Control told about it.

Wales is different. It kept the older, wider rules, so kitchen work and outdoor work remain notifiable there. Scotland and Northern Ireland operate separate systems again. If your property is outside England, the notification position changes, and it is worth checking rather than assuming.

What if notifiable work was never notified?

If a new circuit or a consumer unit change was done and never notified, the work is a Building Regulations breach. Two things are worth knowing.

First, the enforcement window is longer than most guidance online still says. Since 1 October 2023 in England, Building Control can act on a breach for 10 years from completion, not the old 12 months. Plenty of blogs and even some solicitors still estimate 12 months. For work done in the last decade, treat the window as open.

Second, the way to put it right on the record is regularisation. You apply to your local authority Building Control for a Regularisation Certificate. They inspect, may require parts to be opened up so the work can be checked, and often ask for testing by a registered electrician. Costs vary widely by council and there is no national scale; some publish four-figure fees for domestic electrical regularisation. It can also be refused if compliance cannot be shown, and the fee is not refunded.

Selling a house with uncertified electrical work

You are not legally required to hold an EICR to sell a home you live in, unlike a landlord. But the issue will surface. The standard property information form asks about electrical work since 2005, and answering it inaccurately is a misrepresentation risk, so staying quiet is not a safe option. A buyer’s solicitor will usually want the matter resolved before exchange.

At that point people are often steered towards indemnity insurance. It is worth being clear about what that does. Indemnity insurance covers the cost if the council takes enforcement action. It does not confirm the work is safe, it pays nothing if you find a fault yourself, and it covers nothing towards making a dangerous installation safe. It is paperwork cover, not safety cover.

There is also a trap in it. An indemnity policy is void the moment anyone contacts the council about the missing approval, including a well meaning electrician ringing to ask. So the indemnity route and the regularisation route are mutually exclusive, and the order is irreversible. Decide which one you are taking before anyone picks up the phone to Building Control.

For our money, a report you can trust beats a policy that only pays out on enforcement. An EICR that comes back satisfactory removes the buyer’s concern at the source. Where it finds defects, the remedial cost becomes the honest number to work with, rather than a buyer’s guess at a discount.

How to avoid this next time

The way to never be in this position is to ask two questions before any trade touches your wiring.

• Are you a registered electrician, and will I get a certificate? A kitchen or bathroom company that says “we do the electrics” should be asked who actually signs off the electrical work, and what document you will receive.
• Which scheme are you registered with? You can check a firm on the NICEIC or NAPIT online register, or search the Registered Competent Person Electrical site, which covers all the government approved schemes in England and Wales.

One nuance worth knowing: registration attaches to the business, not the individual who turns up. A registered firm can still send someone who is not personally qualified, so it is fair to ask who will carry out and sign off the electrical work specifically.

Commercial premises

The same problem shows up in commercial settings, usually when a shopfitter, a contractor, or a facilities team has had electrical work done without proper certification. The principle is identical: it cannot be retrospectively certified, an EICR is the route to establishing condition, and remedial work is certified by whoever carries it out. On commercial sites the stakes are higher because of insurance, licensing, and the responsible person duties under fire safety law. For the full commercial picture, including the Electricity at Work duty, insurance risk, and who is responsible under a lease, see our companion guide to uncertified electrical work in commercial premises, or our commercial electrical page for how we handle this at scale.
