Commercial Electrician & M&E Contractor in London
Commercial and industrial electrical, mechanical and compliance work across London — installation, planned maintenance and testing, delivered by one accountable contractor.
Commercial & industrial electrical
Installation, alteration and maintenance for occupied and live commercial environments across London.
Mechanical & electrical, delivered together
Most building-services problems happen at the joins — where the electrical contractor stops and the mechanical contractor starts. We deliver both, so the interfaces are our responsibility rather than a coordination risk for you.
That means power and lighting alongside pipework, ventilation, heat pumps and plant connections, with one programme, one set of drawings-as-installed and one handover pack.
Planned maintenance & compliance
Recurring compliance handled on a schedule, so certificates never lapse and you're not chasing dates. See our EICR & electrical safety testing for the full detail.
Sectors we work in
Offices & workplaces
Fit-outs, alterations, lighting upgrades and testing programmes scheduled around occupancy — including evenings and weekends.
Managed residential blocks
Common-part electrics, landlord supplies, emergency lighting and fire systems for managing agents and freeholders, with consistent documentation across a portfolio.
Retail & light industrial
Installation and maintenance in trading environments, phased so the unit keeps operating.
Developers & main contractors
M&E packages on refurbishment and fit-out projects, delivered to programme with full certification at handover.
Accredited & procurement-ready
We hold the accreditations commercial clients and procurement teams ask for, and we can provide documentation for pre-qualification questionnaires and tender submissions.

Amazing experience and professional and experienced. Would recommend.
Used DA to swap out our old fuse board as it was ancient and kept tripping. Lads turned up when they said, got it done in a few hours and left no mess. New unit looks miles better and got all the paperwork through after. Can't fault them
DA Electrical resolved our plumbing issues when fitting our bathroom. Included new pipework as well as connections. Neat tidy work and very considerate, kept us informed every step of the way. Pleased they did the electrics and plumbing. Highly recommended
DA Electrical replaced our old fuse board and sorted the wiring in our flat in Walthamstow. Turned up on time, explained everything clearly, and left the place spotless. Fully certified and a fair price — wouldn't hesitate to recommend them
Easy communication and clear information about costs. Very polite and completed the job to our satisfaction. Thank you!
