Our story

Two trades, one obsessive standard.

Mercer & Volt began the day two electricians realised the homes they loved working in deserved better than a rushed job and a mess to clean up.

Founded in Harrow, 2009

We treat your home like it's listed.

James Mercer and Theo Volt met on a tired Victorian rewire in Kilburn where the previous firm had chased cables straight through original plaster mouldings. They finished that job the way it should have been done — patiently, neatly, with everything made good — and the homeowner's first words were, "why doesn't everyone work like this?"

That question became the business. We deliberately stay small, take on fewer jobs, and put a qualified electrician — not a subcontractor — on every project. We dust-sheet, we tidy as we go, and we photograph the work behind the walls so you know exactly what you're living with.

Today we're the firm that architects, interior designers and careful homeowners across North-West London call when the finish matters as much as the function. We're proud of that, and we intend to keep it that way.

What we stand for

Four things we never cut.

Certified, always

Every job is tested, certified and notified to Building Control. No shortcuts, no exceptions, full paperwork in your hands.

Respect for the home

Dust sheets down, boots off, mess cleared. We leave your home as we found it — only with better wiring inside the walls.

Honest pricing

Fixed quotes before we start and a frank conversation about what's genuinely needed — never what pads the invoice.

Quietly discreet

We work in homes where privacy matters. What we see and do on site stays on site — professional from doorstep to clean-up.

The people on the tools

A small team, by design.
