NICEIC approved, Part P registered and based in Blackheath SE3 — serving homes and businesses across South-East London.
T Phase Ltd is an electrical contractor based in Blackheath, South-East London. We work across the full range of electrical services — from a single socket in a family home to full commercial fit-outs and ongoing testing and maintenance contracts for landlords and managing agents.
Our reputation has been built on a simple principle: do the job properly the first time, keep the customer informed, and leave the property clean. That approach has earned us a 5.0-star rating from 167 Google reviews and a steady stream of work by recommendation across SE London.
Every member of our team is fully qualified, and our work is certified to the BS 7671 wiring regulations. As an NICEIC approved contractor and Part P registered business, our installations are independently assessed against the latest standards — so you can be confident the work is safe, compliant and properly documented.
Every circle on the map below is a cluster of real jobs our engineers completed this year — EICRs, remedial works, consumer unit upgrades and communal testing. We are not quoting to expand into these areas; our engineers are in them every week.
See a selection of the work in our recent projects gallery, or check every area we cover.
Our densest coverage is Blackheath, Greenwich, Lewisham, Eltham, Bromley and Bexley — but we deliver planned EICR and remedial programmes across the South East. If your portfolio sits outside these areas, ask us anyway.
