A local electrical contractor built on doing the job properly.

Who we are

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 4.9-star rating from 159 Google reviews and a steady stream of work by recommendation across SE London.

Qualified, approved and insured

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.

• Reliability — we turn up when we say we will and finish what we start.
• Transparency — clear, fixed quotes with no surprises.
• Care — respect for your home or premises, and a tidy finish every time.
• Standards — fully certified work, every job, without exception.
