Based locally and serving Lewisham SE13 — NICEIC approved electricians for EICRs, rewires, consumer units, fault finding and 24/7 emergencies. Same-day callbacks and fast local response.
T Phase Ltd is a NICEIC approved electrical contractor based on Montpelier Vale in Blackheath, roughly a mile and a half from Lewisham town centre. We work across SE13 every week — the town centre and the new blocks around the station, Ladywell, Hither Green and the Corbett Estate, Lee Green and the streets running up towards Blackheath. EICRs, rewires, consumer unit upgrades, lighting, EV chargers and emergency call-outs, all carried out by City & Guilds qualified engineers and fully certified.
Lewisham has a higher proportion of converted and rented property than almost anywhere else we cover, and that — rather than the postcode — shapes most of what we find.
Converted Victorian terraces in Ladywell and Hither Green. The single most common job in SE13, and the one that produces the most unsatisfactory reports. A house originally wired as one dwelling has been split into two or three flats, and the split was often done on the cheap: one original board serving circuits that now cross between flats, borrowed neutrals between what should be separate installations, no RCD protection, and no clear division between the landlord's supply for the hall and stairs and the supplies to the flats. Sorting the arrangement out is usually a bigger job than the fault that prompted the call — but it is also the difference between a report that passes and one that never will.
The Corbett Estate. Archibald Cameron Corbett's late-Victorian and Edwardian terraces around Hither Green, built from the 1890s onwards, are remarkably consistent — which means the findings are consistent too. Original lath and plaster, back additions added later, and loft conversions wired as an afterthought off an existing circuit. Because the stock is so uniform, we can usually tell you what a rewire will involve in a Corbett house before we have seen yours.
Lewisham town centre and the newer towers. Purpose-built apartments, typically six to eight circuits and a modern board — normally the quickest inspections we do. The work here is EV charging, additional sockets and lighting rather than remedial work, and communal landlord's supplies in the blocks, which are a separate job priced per board.
Lee Green and the Blackheath borders. Larger Victorian villas and 1930s semis, more owner-occupied, and the area where full rewires and consumer unit upgrades outnumber landlord inspections.
Post-war and social housing stock. A substantial part of the borough. Rewires, board changes, communal supplies and programme work, usually run as a batch against a deadline rather than as single jobs.
Lewisham has run a selective licensing scheme since 1 July 2024, covering around 20,000 privately rented properties across most of the borough — Lewisham Central, Ladywell, Lee Green, Brockley, Crofton Park, Catford South, Rushey Green, New Cross, Evelyn, Perry Vale, Sydenham, Forest Hill, Bellingham, Downham, Grove Park and Whitefoot among them. Licences run five years and cost £640. Letting an unlicensed property that should be licensed can attract a penalty of up to £30,000.
The part that concerns us: an Electrical Installation Condition Report is one of the documents the council requires, alongside the EPC and, where there is gas, the gas safety certificate. So in most of SE13 the EICR is no longer only a five-yearly duty under the 2020 regulations — it is part of the paperwork that keeps the licence valid.
Shared houses are separate again. Lewisham has run borough-wide additional licensing for three and four-person HMOs since 5 April 2022, on top of the national mandatory scheme for five or more occupants. Designations and boundaries do change, so check your own address against the council's map rather than relying on what applied to the last property you let.
A valid EICR is a legal requirement at least every five years for rented homes in England, with a copy to the tenant and to the local authority on request. Those duties were extended to the social rented sector in 2025, and existing social tenancies must hold a valid EICR by 1 November 2026.
Lewisham is one of the areas where most of our work arrives in batches rather than one property at a time — a letting agent's managed portfolio, a converted house with three separate tenancies and a communal supply, or a provider working through a programme. Properties booked together in the same area can be scheduled on the same day or run of days, and the certificates come back as one set rather than arriving piecemeal. Tell us the volume and the deadline and we will come back with a schedule.
Our prices are the same in Lewisham as everywhere else in our standard area — there is no call-out charge, no mileage and no parking recharge. EICRs start at £190 + VAT for a one-bedroom flat and run to £300 + VAT for a five-bedroom house, with the certificate included and no separate fee. In a converted house, each self-contained flat is a separate installation and takes its own report; the hall, stairs and landlord's supply are priced per board at £165 rather than per bedroom. If you are letting three flats in one building, that is three certificates plus the communal one, and it is cheaper booked together.
A consumer unit upgrade starts at £800 for up to six circuits. A full rewire runs from £8,000 for a one-bedroom property to £19,400 for a five-bedroom house — the rewire cost guide explains what moves that number, and the EICR cost guide does the same for inspections. Both let you price your own property. The pricing page carries the full schedule and the estimators.
A report is unsatisfactory if it contains any C1, C2 or FI code — a single C2 fails the whole report however sound the rest of the installation is. In converted SE13 flats that is a common outcome and not a disaster.
Remedial work is quoted as a separate fixed price, carried out by our own engineers, and the certificate is re-issued once it is done. You are not handed a list of faults and left to find a second trade — which matters more than usual here, because a licensing deadline does not wait while you find a second contractor. You are of course free to use any qualified contractor for the remedials if you would rather compare.

"Needed EICRs for two rental flats in Hither Green. Booked together, done in a day, paperwork spot on."
"Tracked down an intermittent fault two other electricians had missed. Knowledgeable and fairly priced."
"Added sockets and new lighting throughout. Tidy, friendly and certified — exactly what we wanted."
From £190 + VAT for a one-bedroom flat, rising to £300 + VAT for a five-bedroom house, with the certificate included. In a converted house each self-contained flat is a separate installation and takes its own report, and the hall, stairs and landlord's supply are priced per board at £165. There is no call-out charge, no mileage and no parking recharge in SE13.
Most privately rented homes in the borough have needed a selective licence since 1 July 2024 — around 20,000 properties across wards including Lewisham Central, Ladywell, Lee Green, Brockley and Crofton Park. An EICR is one of the documents the council requires, alongside the EPC and gas safety certificate, so in most of SE13 the report is part of keeping the licence valid rather than only a five-yearly duty. Designations do change, so check your address against the council's map.
They sit under a different scheme. Lewisham has run borough-wide additional licensing for three and four-person HMOs since 5 April 2022, on top of the national mandatory scheme for properties let to five or more unrelated occupants. The electrical requirements are at least as strict, and shared houses are inspected more often in practice because of the wear on the installation.
Four, in most cases — one for each self-contained flat, plus one for the landlord's supply serving the hall, stairs and any communal lighting. Booked together they are cheaper and can usually be done in a single visit, and you get the set back at the same time rather than piecemeal.
Because of how the conversion was done. A house wired as one dwelling gets split into flats, and frequently the original board is left serving circuits that now cross between separate tenancies, with borrowed neutrals and no RCD protection. Any one of those is a C2, and a single C2 makes the whole report unsatisfactory however sound the rest of the installation is.
No. Lewisham SE13 is inside our standard area — we are based on Montpelier Vale in Blackheath, about a mile and a half away, and work across SE13 every week. Prices are the same as everywhere else in our standard coverage.
Yes. Managed portfolios, converted houses and blocks are a large part of what we do in SE13. Properties booked together in the same area can be scheduled on the same day or run of days, and the certificates come back as one set. Tell us the volume and the deadline and we will come back with a schedule.
A report is unsatisfactory if it contains any C1, C2 or FI code. We explain what is needed, quote the remedial work as a separate fixed price, carry it out with our own engineers and re-issue the certificate — which matters when a licensing deadline is running. You are free to use any qualified contractor for the remedial work instead.
We offer 24/7 emergency call-out and same-day callbacks across SE13. Fast-track booking within 48 hours is £50, and evening, weekend or bank holiday attendance is charged at 1.5 times the standard rate.
