EICR Testing London - Inspection, Codes and Certificate
EICR testing London wide is the core of what we do, and for most people it's the first job on the list. An electrical installation condition report tells you whether the fixed wiring in a property is safe to keep using - and if it isn't, exactly what needs putting right and how urgently.
Here's how a test actually runs. The installation gets isolated, then dead tests across the circuits - continuity, insulation resistance - then live tests: earth fault loop impedance, RCD trip times, functional checks on the switchgear. Every observation gets coded. C1 means danger is present now. C2 means potentially dangerous. C3 is an improvement recommendation, and FI means something can't be signed off until it's investigated further. One C1 or C2 anywhere on the schedule and the whole report is graded unsatisfactory.
That's usually where the phone starts ringing. An unsatisfactory eicr isn't a disaster - but it does start a clock. Private rented tenancies have sat under a five-yearly landlord duty since April 2021, and the 28 day remedial deadline counts from the date on the report, not the day you got round to reading it. Letting agents are increasingly blunt about it too: no current satisfactory eicr certificate London side, no marketing the property.
We don't stop at the paperwork. Fault finding when a circuit won't hold. Protection added where a board never had any. And where cabling has genuinely had its day, an electrical rewiring service that replaces circuits properly instead of patching the same fault for the third time.
One flat in West London gets the same test schedule, the same engineer standard and the same documentation as a 200-home portfolio programme. Commercial premises the same - offices, shops and small units around Central London where it's the insurer or the lease driving the date rather than a tenancy.
Leave a C2 for a year and it rarely stays a C2.
Electrical Problems We Fix in London
Some of these need an emergency electrician today. Others can wait for a diary slot. Here's how we tell them apart.
Council Demands and Enforcement Notices
"The council's asking for my EICR." "There's an improvement notice through the door." Usually it means no report exists or the last one expired - or an unsatisfactory result was never put right and evidenced in time. Councils get the report within seven days, and penalties under the 2020 Regulations reach £40,000 per breach (SI 2025/1043, in force 1 November 2025). Treat an enforcement letter as a legal deadline, not admin.
Total Power Loss in a Property
No electricity in the whole house, neighbours unaffected, main fuse suspected. Often the main switch or an RCD refusing to hold against a fault inside the installation - sometimes it's supply side, a network outage or a failed cutout fuse, which is a different phone call entirely. Once the network's ruled out, a property that can't hold its main switch is an emergency, especially with vulnerable occupants.
Old Wiring and Whole-House Rewires
"Does my house need rewiring?" - normally asked after a surveyor flags it, or after buying somewhere and pulling off a light fitting. Often original rubber or lead-sheathed cable still in service, lighting circuits with no earths, or part-rewires that never touched the oldest bits. Plannable, mostly. But testing decides that: whether a rewire is really needed comes from results, not age.
Fixed-Wire Testing for Business Premises
Insurance wants a current test certificate, the lease renewal's coming, or nothing's been recorded since the last occupier walked out. The legal duty to keep an installation maintained is evidenced in practice by periodic testing on a three-to-five year cycle. Plannable against your renewal date - though C1 or C2 findings in an occupied premises turn urgent immediately. Commercial fixed-wire testing starts with what's actually installed.
Two of the four above have a deadline attached. The other two get one the moment somebody gets hurt.
What London's Housing Stock Means for Your Inspection
The building tells you a lot before the first test lead goes on. That's not trivia - it changes what a job costs you.
Ex-council and post-war blocks across East London and South East London still throw up original boards with no RCD protection at all, which is a straightforward fail the moment landlord electrical safety duties bring a flat into the five-year cycle, and normally a local consumer unit upgrade rather than anything dramatic. In 1960s to 80s purpose-built flats it's different: alterations stacked up across tenancies, shared supplies nobody kept records for. North London's period conversions hide theirs behind smart new fittings - old cable, missing earths on lighting circuits, junction boxes plastered into a wall.
Social landlords work to their own dates. The Social Housing (Electrical Safety) Standards 2025 covers new social tenancies from 1 December 2025 and every existing one by 1 May 2026.
Then the everyday calls - an RCD tripping every few days, half the sockets dead while the rest are fine, a scorch mark or a burning smell around a switch. In stock this age, none of those are guessable from the doorstep. They need testing to find, and a fault ignored in March is a much bigger bill by autumn.
Electrical Safety Services Across London
Seven jobs, booked separately - though most people arrive needing one and leave having sorted two. Pick whichever matches your situation.
EICR Certificate
Fixed wiring tested against BS 7671, ending in a satisfactory eicr certificate or a coded schedule of what needs correcting. For landlords, homeowners and commercial premises.
PAT Testing
Portable appliance testing for offices, shops, schools and rented homes - appliances inspected, tested and recorded for insurers and duty holders.
Landlord Electrical Safety Package
One booking covering the EICR, PAT testing and the smoke and CO alarm compliance a tenancy needs. Scheduled together, certificated together.
EICR Remedial Work
Putting right the C1, C2 and FI observations on a failed report - repairs through to full circuit corrections - then re-testing so it can be reissued as satisfactory.
Emergency Electrician
24/7 call-outs for power loss, tripping circuits, burning smells and exposed conductors. Made safe first, then repaired.
Consumer Unit / Fuse Box Upgrade
Old fuse boxes swapped for a modern RCD or RCBO board to current standards - the single most common fix behind a failed electrical safety certificate London landlords have to produce.
Rewiring
Full and partial rewires where wiring is ageing, unsafe or overloaded - new cable, accessories and board, with an Electrical Installation Certificate at handover.
Not sure which one? The inspection decides it for you, which is why it's the sensible place to start.
Why Choose Us for Landlord Electrical Safety
Two electricians can test the same flat and hand you two very different reports. Nobody tells you that up front, so here it is.
Over-coding is the expensive version - everything marked C2, a rewire quoted, thousands of pounds of work you never needed. Under-coding is the dangerous one: a tidy-looking pass on an installation with missing main bonding or an overloaded ring nobody bothered to check. Our engineers hold the qualifications required for the service they carry out, and they code what the evidence supports. If something genuinely can't be judged without opening it up, it gets an FI - not a shrug and a tick.
You get the real document at the end. Not a one-page summary: the observations, the schedule of inspections and the schedule of test results - the thing a council officer, an insurer or a letting agent actually asks to see. Where remedials are needed they're itemised against the observations, priced in writing after the inspection, so you can see which items are a legal requirement and which are an improvement you could sit on for a year.
Practical stuff matters too. On a let property we can pick up the PAT testing certificate during the same visit rather than sending someone back a fortnight later. Someone answers the phone at three in the morning on a Sunday, so an emergency doesn't wait for office hours to be logged.
And we work across the whole spread - private landlords, letting and managing agents, housing associations and councils, alongside homeowners who've had a scare and buyers whose survey flagged the wiring.
The cheapest test on the market is the one you pay for twice: once for the visit, again when the report doesn't stand up to the person you have to send it to.
Book an EICR With the Price in Writing
Find out what's wrong before you spend a penny fixing it. Book the inspection and you'll have the coded C1, C2 and C3 observations in front of you, plus a written price for any work they trigger - based on what the engineer actually found, not a number invented over the phone. Then you decide what's urgent and what can wait.
Questions We Get Asked About EICR Certificates
How much does an inspection cost?
There's no flat rate, and be wary of anyone quoting one blind. Price follows the size of the installation - how many circuits, how many boards, whether it's a one-bed conversion or a shop with three-phase supply. We price on what's there, and any remedial work is quoted separately once we've seen the results, so you're never paying for guesswork. Worth pinning down before a deadline forces the choice for you.
How long does it take, and will the power be off?
For a flat, usually a few hours. Larger houses and commercial premises take longer, and a big block gets phased. The supply goes off in stages, circuit by circuit, rather than all day - most tenants stay put throughout. Same-day appointments are available if the timing's tight, though the report itself is written up after the visit, not handed over on the doorstep.
Can I do any of this myself?
No - and not just because of the kit. Periodic inspection needs calibrated instruments and someone competent to interpret what they show. Under Part P of the Building Regulations, notifiable work in a home such as a new circuit or a consumer unit replacement has to go through building control or a registered competent person who can self-certify. Amateur alterations are one of the most common things we find and code, which tells you how well DIY goes here.
What happens if it comes back unsatisfactory?
C1, C2 and FI items all have to be dealt with. For a private rented home under the Electrical Safety Standards in the Private Rented Sector (England) Regulations 2020, that work must be done and evidenced within 28 days of the report, and a council can ask for proof. The sooner remedials are quoted, the more of that window you keep.
Do I need one if I'm not a landlord?
Owner-occupied homes have no legal requirement - IET Guidance Note 3 suggests up to ten years, or at change of occupancy, and buyers and sellers often want one anyway. Commercial premises come under the Electricity at Work Regulations 1989, typically on a three-to-five year cycle, shorter in higher-risk settings. If you're letting the place out, a landlord electrical inspection rolls the testing and alarm checks into one visit instead of three.
Get Your Electrical Work Quoted in Writing
Whatever the report throws up - a couple of C2 observations, a board change, a full rewire - you'll have it quoted in writing before anyone lifts a floorboard. Bookings are taken 24/7. Same job either way, whether it's one flat in South West London or a managing agent's entire block, and don't sit on an unsatisfactory eicr while you shop around.
