Based locally and serving Catford SE6 — 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, about three miles from Catford town centre and in the same borough. We work across SE6 every week — the Corbett Estate, Rushey Green and the Broadway, Bellingham and Southend Village, Catford Bridge and the Ravensbourne streets, and out to Downham and Whitefoot. EICRs, rewires, consumer unit upgrades, lighting, EV chargers and emergency call-outs, all carried out by City & Guilds qualified engineers and fully certified.
Catford is not one housing stock, it is four, and the report you get depends almost entirely on which of them you live in. There is the late-Victorian and Edwardian speculative terrace, overwhelmingly the Corbett Estate. There is the inter-war London County Council cottage estate at Bellingham and Downham. There is the flat above a shop on Rushey Green and the Broadway. And there is the post-war and later block, from the deck-access schemes around the town centre to the newer infill on the Ravensbourne. Each fails in a different way, and a quote that does not ask which one you are in is a quote made without looking.
Archibald Cameron Corbett built roughly three thousand houses across Catford and Hither Green between 1896 and the First World War, and the Scottish street names — St German's, Torridon, Minard, Ardgowan, Fordmill, Sandhurst — still mark out the estate today. They are good houses: bay-fronted, generously proportioned, and built to a consistent specification, which is exactly why the electrical findings are so consistent too.
Almost all of them were originally gas-lit and first wired between the wars, in rubber or lead-sheathed cable. Most were rewired once, somewhere between the mid-1960s and the early 1980s, in early PVC. What that means in practice is that the cable in a Corbett house is frequently forty to sixty years old rather than fifteen — serviceable, but at the point where the insulation on the lighting circuits has begun to harden, particularly in a hot loft. The other recurring finding is a lighting circuit with no circuit protective conductor, which rules out metal fittings and metal switch plates until it is put right.
Add to that a rewireable fuseboard in the cupboard under the stairs, no RCD protection, a main earthing conductor sized for a much smaller installation, and no main protective bonding to the incoming gas and water, and you have the standard Corbett EICR. None of it is unusual and none of it is alarming. It is simply what a house of that age and that history looks like, and it is why we quote Corbett houses on the honest assumption that a consumer unit upgrade will need earthing and bonding work alongside it.
A large share of the Catford terraces closer to Catford Bridge, Ladywell and the Hither Green borders have been split into two or three flats. The conversion work was often done before anyone thought carefully about how the electrics should be divided, and the result is the single most common unsatisfactory finding we record in SE6: one original supply and board serving circuits that now cross between separate tenancies, with a neutral borrowed from one flat's circuit to complete another's.
It matters for two reasons. It is a C2 — potentially dangerous — so it fails the report outright. And it means that isolating one flat does not make the other safe to work on, which is a genuine hazard for whoever comes next. Putting it right usually means separating the supplies properly rather than patching the board, so we price it as its own job and set that expectation before we attend rather than after.
Bellingham and Downham are LCC cottage estates of the 1920s and early 1930s, built at scale and to a pattern. The houses have generally been rewired at least once by the landlord, and the wiring is often in better condition than the Corbett stock — but circuit counts are low by modern standards, and kitchens and bathrooms are where the additions have happened. Extended ring finals, spurred-off outdoor sockets and shower circuits added later without the supply being reassessed are the usual findings.
Worth knowing if you are in Downham or Whitefoot: the estate straddles the boundary between the London Borough of Lewisham and the London Borough of Bromley, and the line runs through the middle of it. Which council you deal with for consents, and which borough's rules on rented property apply to you, depends on which side of that line your house sits — and neighbours on the same street are sometimes in different boroughs. If you are not sure, tell us the full postcode and we will tell you which one you are in.
Rushey Green and Catford Broadway carry a long run of flats above commercial units, and those are their own category. The supply arrangement is frequently a shop meter, a landlord's supply and one or more flat supplies sharing an intake, with alterations made by whoever was trading at the time. Communal areas, stairwells and external lighting sit on the landlord's supply and need their own report. We price communal work per landlord's supply at £165 per board rather than pretending it fits a domestic ladder, and we will always tell you how many boards there are before we start.
Rented homes in England need a satisfactory Electrical Installation Condition Report at least every five years, with a copy to the tenant and to the local authority on request. From 1 November 2026 that requirement extends to existing social tenancies as well, which is why social landlords and managing agents across Lewisham are working through programmes now rather than in the autumn.
Lewisham also operates licensing schemes for privately rented property, and the requirements are not the same in every ward — the council's register is the place to check your address. What we can tell you is that an EICR is the document a licensing officer asks for first, and that a report which is unsatisfactory is worse than no report at all if the remedial work has not been programmed. We quote remedials as a separate fixed price, carry them out and re-issue the certificate, and you are free to use any qualified contractor for that work instead.
An EICR runs from £190 + VAT for a one-bedroom flat to £300 + VAT for a five-bedroom house, certificate included, with no call-out charge, no mileage and no parking recharge. Communal areas are £165 per landlord's supply. A consumer unit upgrade starts at £800 plus £50 per circuit, and on Corbett houses you should budget for earthing and bonding on top — we check on survey and price it from our published rates rather than as a surprise. Full rewires run from £8,000 for a one-bedroom flat to £19,400 for a five-bedroom house, excluding plastering and decoration. The pricing page has estimators for all three, and the EICR cost guide and rewire cost guide set out how the figures are built up if you would rather compare.
From £190 + VAT for a one-bedroom flat, rising to £300 + VAT for a five-bedroom house, with the certificate included. Communal areas are priced per landlord's supply at £165 per board. There is no call-out charge, no mileage and no parking recharge in Catford.
No. Catford SE6 is inside our standard area and in our own borough — we are based on Montpelier Vale in Blackheath, about three miles away, and work across SE6 every week. Prices are the same as everywhere else in our standard coverage.
Because they were wired before the current standards existed and were usually rewired only once, decades ago. The main earthing conductor is frequently sized for a much smaller installation, and main protective bonding to the incoming gas and water is often missing entirely. Neither is dangerous on its own, but both are recorded on the report, and both have to be put right before a new consumer unit can be certified. We survey for it and price it openly rather than discovering it on the day.
It usually is. Where one original board serves circuits that cross between separate flats, the neutral is often borrowed from one circuit to complete another. That is a C2 — potentially dangerous — so it fails the report, and it also means switching off one flat does not make the other safe to work on. The fix is to separate the supplies properly rather than to patch the board, so we price it as its own job.
It depends on the street, and sometimes on which end of the street. The Downham and Whitefoot estates straddle the Lewisham–Bromley boundary and the line runs through the middle of them, so neighbours can be in different boroughs. It matters for consents and for rented-property rules. Send us the full postcode and we will tell you which side you are on.
Yes, and it is a large part of what we do in Lewisham. 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.
At least every five years for rented homes in England, with a copy supplied to the tenant and to the local authority on request. This now applies to social landlords as well as private ones — existing social tenancies must hold a valid report by 1 November 2026.
A report is unsatisfactory if it contains any C1, C2 or FI code — one C2 fails the whole report. 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. 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 SE6. Fast-track booking within 48 hours is £50, and evening, weekend or bank holiday attendance is charged at 1.5 times the standard rate.
