Serving Dulwich Village, East Dulwich and West Dulwich — 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, a short run west along the South Circular from Dulwich. We work across SE21 and SE22 — Dulwich Village and College Road, East Dulwich and Lordship Lane, West Dulwich and Rosendale, Sydenham Hill and Dulwich Wood, and the Herne Hill and Peckham borders. EICRs, rewires, consumer unit upgrades, lighting, EV chargers and emergency call-outs, all carried out by City & Guilds qualified engineers and fully certified.
Dulwich has a wider spread of property values than almost anywhere else we work, and the electrical picture follows it exactly. At one end there are large detached and semi-detached houses around the Village, College Road and Court Lane where the installation has grown by accretion over three or four decades and the circuit count runs well into the twenties. At the other there are East Dulwich terraces converted into two or three flats where the whole building is still running off arrangements made when it was one house. In between sit the 1930s semis of West Dulwich and the post-war estate stock. They fail in entirely different ways, and the price of the job follows the stock rather than the address.
This is the one thing about working in Dulwich that catches people out, and no other electrician's website in the area explains it. A large number of freehold houses across SE21 and SE22 sit within the Dulwich Estate's Scheme of Management. Under it, changes to the external appearance of a property need the Estate's consent — and that consent is separate from, and additional to, anything the council's planning department says. All tree work needs prior consent too.
For electrical work that matters more often than you would expect. An EV charge point on a front or side elevation, external lighting, a meter box moved or re-cased, a new external supply route, solar panels and any cable run visible from the street can all fall within it. None of this stops the work happening. It does mean the sensible order is: confirm with the Estate first, then have us quote, rather than the other way round. We are happy to hold a quote while you do, and to describe the installation in the terms an application needs.
Internal work — rewires, consumer units, additional circuits, lighting inside the property — is not affected. Neither are conservation-area rules, which run separately again through the council. If you are not sure which of the three applies to you, tell us what you are planning and we will tell you who you need to ask.
On the larger Village, Court Lane, Calton Avenue and College Road properties we quote on circuit count rather than on bedrooms, because bedrooms stop being a useful proxy at this size. A five-bedroom house here routinely carries garden and driveway lighting, an outbuilding or garden studio on its own submain, a garage, a home office, an alarm and CCTV, underfloor heating and now a charge point — twenty-plus circuits and sometimes a second consumer unit fed from the first. Testing all of that properly takes a full day and occasionally two, and the honest figure reflects that.
The recurring findings are consistent: a board that was adequate when it went in and has since had circuits added beyond what it was designed for, submains to outbuildings installed without the earthing arrangement being reconsidered, and outdoor circuits without RCD protection. Where original 1930s or earlier fabric survives in the roof and under the floors, we also still find rubber-insulated cable in service on lighting circuits.
The Victorian terraces off Lordship Lane — Barry Road, Crystal Palace Road, Underhill Road, Melbourne Grove, Landcroft and the streets around them — are the densest conversion stock in the area, and they produce the single most common unsatisfactory finding we record in SE22: one original supply and board serving circuits that now cross between separate flats, with a neutral borrowed from one circuit to complete another.
It is a C2 — potentially dangerous — so it fails the report outright, and it also means that isolating one flat does not make the other safe to work on. Putting it right means separating the supplies properly rather than patching the board, so we price it as its own job and say so before we attend rather than after. The other standard conversion findings are a shared smoke alarm circuit fed from whichever flat happened to be convenient, and communal hall and stair lighting sitting on a tenant's meter instead of the landlord's supply.
The 1930s semis around Rosendale Road, Park Hall Road and the streets below Sydenham Hill are a different job again. These were built with generous rooms and mean circuit counts, and almost all have had a kitchen extension, a loft conversion or both. The usual findings are an extended ring final that has been spurred from repeatedly, a shower circuit added later without the main supply being reassessed, and a metal-clad rewireable board that is serviceable but has no RCD protection anywhere on it.
Most of SE21 and SE22 is in the London Borough of Southwark, but not all of it. The western edge towards Herne Hill and Half Moon Lane runs into Lambeth, and the Sydenham Hill and Dulwich Wood side touches Lewisham. It matters for building control notifications, for conservation-area consents and for the rules that apply to rented property, which are not the same in all three. Send us the full postcode and we will tell you which borough you are in before anything is booked.
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. Dulwich has a heavy concentration of managing and letting agents holding converted-flat portfolios, and those are straightforward for us to programme: properties booked together in the same area are scheduled on the same day or run of days, and the certificates come back as one set rather than arriving piecemeal.
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. Larger Village and College Road houses are quoted on circuit count rather than bedrooms, and we tell you the figure before we attend. A consumer unit upgrade starts at £800 plus £50 per circuit. 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.

Possibly. A large number of freehold houses in SE21 and SE22 sit within the Dulwich Estate's Scheme of Management, under which changes to the external appearance of a property need the Estate's consent — separately from anything the council requires. A charge point on a front or side elevation, external lighting, a relocated meter box or a visible external cable run can all fall within it. Internal work does not. Check with the Estate before booking; we are happy to hold a quote while you do.
No. SE21 and SE22 are inside our standard area — we are based on Montpelier Vale in Blackheath and work across Dulwich regularly. Prices are the same as everywhere else in our standard coverage.
Because on the larger Village, Court Lane and College Road properties bedrooms stop predicting the size of the job. Garden and driveway lighting, an outbuilding or studio on its own submain, a garage, a home office, alarm and CCTV, underfloor heating and a charge point can take a five-bedroom house past twenty circuits, sometimes with a second consumer unit fed from the first. Every circuit has to be tested individually, so the circuit count is what the time and the price actually follow.
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 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.
Most of SE21 and SE22 is Southwark, but the western edge towards Herne Hill and Half Moon Lane is Lambeth, and the Sydenham Hill and Dulwich Wood side touches 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.
Yes. Rewiring a listed building can require listed building consent where the work affects its character, and it always calls for an approach that keeps chasing and making good to a minimum — running cables through existing voids and under floors rather than cutting into original plaster. Conservation-area rules run through the council and are separate from the Dulwich Estate's Scheme of Management, so it is worth checking both.
Yes. Converted-flat portfolios are a large part of our Dulwich work. 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.
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.
