What we cover
Sockets and switches are the most-handled part of a home's electrics — moved when you redecorate, swapped when a finish changes, replaced when an appliance overheats them. Every London install we carry out is by a Part P registered electrician working to the 18th Edition, with a Minor Works Certificate issued before we leave so the work is recorded for any future EICR.

How it works
Call or message
Send a photo of the existing point or where you want the new one to the WhatsApp number. A fixed price is confirmed inside an hour. Same-day slots usually available across Zones 1–3.
Booked slot
Electrician arrives in a marked van with stocked 2.5mm and 1.5mm twin-and-earth, back-boxes, accessories in chrome / brass / white, drill cores and a dust-extracted SDS for clean chasing.
Install and test
Power isolated, RCD protection verified, ring or radial continuity confirmed, polarity and Zs measured at the new accessory with a calibrated MFT before the cover plate goes on.
Certificate & clean-up
Digital Minor Works Certificate emailed before we leave, dust hoovered, off-cuts and packaging removed. 12-month workmanship guarantee on every accessory.
Outdoor and kitchen socket work
Two jobs that come up constantly in London — kitchen plinth sockets under the cabinets for kettles, toasters and air fryers, and outdoor IP66 sockets on patios, garden offices and EV trickle charge points. Both have their own rules under BS 7671: kitchen accessories must sit outside the splash zone of any sink (zone 0/1), and outdoor sockets must be IP66 rated and protected by a 30mA RCD or RCBO.
Outdoor installs typically pull a 2.5mm twin-and-earth spur through a wall via a Wiska or Schneider IP66 gland, with an earth bond to any nearby metalwork and a Type A RCD upgrade at the consumer unit where the existing protection is Type AC. Garden offices over 7m of cable run get a dedicated RCBO and a sub-main isolator.

Burnt and scorched sockets — same day
A discoloured, scorched or melted socket is treated as an emergency. The cause is almost always a loose terminal under load — a high-draw appliance like an oven, kettle or hair dryer pulling 10–13A through a connection that has worked loose over time, generating heat at the brass contact and slowly carbonising the plastic. Left in service it is a fire risk.
Same-day attendance is standard across Zones 1–3. The damaged accessory is removed, the back-box and cable tails are checked for heat damage, and if the cable insulation is intact a new metal-clad or moulded socket goes in. If the heat has compromised the conductor, the affected length is cut back into a maintenance-free junction box (Wago / Hager Klik) or the run is replaced. Every burnt-socket job is logged on a Minor Works Certificate.
Testing and certification
Every new or moved accessory is tested before the cover plate goes on. Continuity of the protective conductor, polarity at the new outlet, ring final continuity if the spur ties into a ring, insulation resistance and earth fault loop impedance (Zs) at the new accessory — all measured with a calibrated Megger MFT1741 or Fluke 1664 FC and recorded against the design value on the certificate.

The Minor Works Certificate is emailed before we leave — keep it with the rest of your EICR paperwork so the next periodic inspection has a clean audit trail back to the date of the install.
Areas covered
Socket and switch installs are carried out across all 32 London boroughs and the City of London. Heaviest demand comes from central and inner London — kitchen renovations, decorating jobs, USB upgrades, smart-home retrofits.
