Learn moreA certified electrician for every London borough
London's property mix runs from Victorian terraces and mansion-block conversions to new-build apartments and commercial units — and each brings its own electrical demands. We see everything from ageing rubber-insulated wiring in period homes to overloaded boards in flats fitted out decades ago. Whatever the building, the process is the same: honest assessment, clear quote, certified work.
Our 24/7 emergency service covers every London zone. There's no call-out charge — you pay only for the work carried out — and our vans carry standard parts, so the majority of faults are fixed on the first visit.
"Called at 9pm with an electrical fault and DM Electrotechnical were there within the hour. Sorted the problem quickly and charged a very fair price."
London — Frequently Asked Questions
Do you cover all London boroughs?
Yes. We work across every London borough, with the fastest response times in south and south-east London thanks to our Swanley base. For central and north London we'll always give you an honest travel estimate when you call.
Why does NAPIT registration matter when choosing a London electrician?
NAPIT registration means our work is independently assessed and we can self-certify notifiable work to Building Control — you get legal certification without involving the council. Unregistered work can void insurance, block property sales, and leave you liable under Building Regulations.
Do you offer 24/7 emergency cover across London?
Yes — 24 hours a day, 365 days a year, across all London zones. There is no call-out charge; you only pay for the work carried out, and we quote before starting.
