Based locally and serving Eltham SE9 — NICEIC approved electricians for EICRs, rewires, consumer units, EV chargers, 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 Eltham High Street and in the same borough for most of SE9. We work across Eltham every week — the Progress Estate at Well Hall, the inter-war semis along Court Road and Westmount Road, Middle Park and Horn Park, Avery Hill, New Eltham and out to Mottingham. EICRs, rewires, consumer unit upgrades, lighting, EV chargers and emergency call-outs, all carried out by City & Guilds qualified engineers and fully certified.
Eltham is the most consistent housing stock of anywhere we cover, and that is genuinely useful — it means we can usually tell you what an inspection will find before we attend. The overwhelming majority of SE9 is inter-war and immediately post-war suburban housing, built between about 1915 and 1939 and owner-occupied ever since. Very little of it has been converted into flats, which removes the single biggest source of unsatisfactory reports elsewhere in South-East London.
What replaces it is a different pattern. These houses were wired once when they were built, rewired once somewhere between the 1960s and the 1990s, and then extended. The findings almost always sit at the joins: where the kitchen extension met the original ring final, where the garage or the garden room was fed, where the shower went in, and where the board was changed without the earthing being reconsidered.
The Progress Estate is the most distinctive stock in SE9 and it needs treating as its own category. Built at extraordinary speed in 1915 to house Woolwich Arsenal munitions workers, it runs to around 1,300 Arts and Crafts houses and cottages, and it is a conservation area with a good deal of original external fabric still in place.
Two things follow from that. Technically, these are solid-wall properties with restricted routes for cable, so a rewire here is a job that has to be planned rather than improvised — running through existing voids, under floors and in original chases rather than cutting new ones across original plaster. And practically, anything that changes the external appearance — a charge point on a front elevation, external lighting, a meter box moved or re-cased — sits inside a conservation area, so it is worth checking with the Royal Borough of Greenwich before the work is booked rather than after. We are happy to hold a quote while you do.
Across the bulk of SE9 the standard property is a three-bedroom inter-war semi, and the standard report is remarkably repeatable:
A consumer unit that is serviceable but has no RCD protection on socket circuits or on cables buried in walls at less than 50 mm. A ring final that has been extended into a kitchen extension and spurred from repeatedly since. An electric shower added at some point without the main supply being reassessed. A garage or outbuilding fed by a submain that was run before anyone thought carefully about its earthing arrangement. And in the loft, on lighting circuits, rubber-insulated cable that is still in service and now well past the point where the insulation stays flexible.
None of that is unusual for the age of the stock. It is why we quote Eltham consumer unit upgrades on the honest assumption that earthing and main protective bonding may need bringing up to standard alongside — we check on survey and price it from our published rates rather than discovering it on the day.
Eltham has more off-street parking than almost anywhere else we work, which makes it one of our busiest areas for charge point installation. The part that catches people out is not the charger, it is the earthing.
Most SE9 properties are on a PME supply, where the supply neutral and earth are combined. An outdoor charge point on a PME earth needs either a separate earth electrode or a device that detects a broken supply neutral and disconnects — most modern chargers have that protection built in, but not all of them, and the choice of unit is what decides whether an earth rod has to go in. The other question is capacity: a 7 kW charger on a house that already has an electric shower, an oven and a heat pump may need a load-management setup or a supply upgrade from the DNO. We check both before quoting, because a price given without those answers is a price that changes.
Most of SE9 is in the Royal Borough of Greenwich, but not all of it. Mottingham straddles the boundary with the London Borough of Bromley, and the Grove Park side runs into Lewisham. It matters for building control notifications, for conservation-area consents and for the rules that apply to rented property, which are not identical across the three. Send us the full postcode and we will tell you which borough you are in before anything is booked.
SE9 has a smaller rented sector than most of our area, but it is growing, and the duty is the same everywhere: 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 extends to existing social tenancies as well. Licensing requirements differ by borough and by ward, so the council's register is the place to check your address. 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, with earthing and bonding priced separately from our published rates where it is needed. 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 Eltham.
No. Eltham SE9 is inside our standard area and, for most of the postcode, in the same borough as our office — we are based on Montpelier Vale in Blackheath, about three miles away. Prices are the same as everywhere else in our standard coverage.
The same handful of things, in most cases: a board with no RCD protection on socket circuits or on cables buried in walls, a ring final extended into a kitchen extension and spurred from since, a shower circuit added later without the supply being reassessed, a garage or outbuilding submain whose earthing was never reconsidered, and rubber-insulated cable still in service on lighting circuits in the loft. None of it is unusual for the age of the stock.
Because earthing and main protective bonding are not included in the consumer unit figure, and on inter-war stock they often need bringing up to standard before a new board can be certified. We survey for it and price it from our published rates rather than raising it on the day. The consumer unit itself starts at £800 plus £50 per circuit.
Quite possibly. The Progress Estate at Well Hall is a conservation area with a great deal of original external fabric, so anything that changes the external appearance — a charge point on a front elevation, external lighting, a relocated or re-cased meter box — is worth checking with the Royal Borough of Greenwich before the work is booked. Internal work is not affected. We are happy to hold a quote while you check.
It depends on the charger. Most Eltham properties are on a PME supply, where the supply neutral and earth are combined. An outdoor charge point on a PME earth needs either a separate earth electrode or a device that detects a broken supply neutral and disconnects — most modern units have that protection built in, but not all, and the unit chosen is what decides it. We confirm which applies to your property before quoting.
That is how it has to be done. These are solid-wall properties with restricted cable routes, so the work is planned around existing voids, floor voids and original chases rather than cutting new ones across original plaster. It takes longer than a rewire on a standard semi and we price it accordingly, but making good is kept to a minimum by design rather than by luck.
Most of SE9 is the Royal Borough of Greenwich, but Mottingham straddles the boundary with Bromley and the Grove Park side runs into Lewisham. It affects building control notifications, conservation-area consents and the rules on rented property. Send us the full postcode and we will confirm which one you are in.
We offer 24/7 emergency call-out and same-day callbacks across SE9. Fast-track booking within 48 hours is £50, and evening, weekend or bank holiday attendance is charged at 1.5 times the standard rate.
