Commercial Electrician & M&E Contractor — East London
DA Electrical London is registered and based in Walthamstow, E17 — this is our home turf. We fit out and rewire commercial units across East London and Waltham Forest, from converted industrial space to new-build ground-floor shells, and hand over a full test and certification pack.
The building stock in Walthamstow and East London
Waltham Forest and the boroughs around it carry a distinctive commercial mix: former industrial and warehouse buildings now let as workshops, studios and light commercial space; high-street parades of small retail and trade units; new-build and conversion blocks with commercial space at ground level; and small managed workspace above shops and along former yards. Almost none of it was built with its current commercial use in mind, and that shapes the electrical work more than the postcode does.
What a converted or new-build unit actually needs
A warehouse converted into studio or trade units, or a new-build block with commercial floors under residential above, rarely has a supply and distribution layout that suits the tenant fitting it out. The incoming supply, the sub-mains route and the containment path all have to be worked out for a structure that was never designed to carry them — and worked out again for the next unit along, because no two conversions are quite the same.
That's the difference between this page and a general commercial electrics page: converted and new-build units being fitted out for the first time, or refitted for a new occupier, need different work from maintenance on an established commercial building — and East London has a lot of the former.
The wider commercial service
Everything on this page sits inside the same commercial electrical and M&E service DA Electrical London delivers across London — see the full commercial electrician & M&E page for planned maintenance, sectors and accreditations, rather than us repeating it here. What's different on this page is the emphasis: converted and new-build commercial units, and the first-fix through to certification sequence that goes with them.
Compliance testing and certificate renewal for an existing commercial unit — once it's occupied and trading — is covered in detail on our EICR & electrical safety testing page. That page is where to go once a unit is fitted out and needs its periodic inspection; this one is about getting it there in the first place.
Who this page is for
Local developers & main contractors
If you're converting a warehouse or building new commercial units in Walthamstow or the wider East London area, we work as the electrical subcontractor on your programme — sequencing first-fix and second-fix around other trades, and handing over a completion pack that matches what a building control officer or client wants to see.
Managing agents
For a managed block with commercial units at ground floor, we can fit out an empty unit for a new tenant, extend or alter an existing sub-mains and distribution layout, and provide the certification your file needs before a unit changes hands.
Small commercial occupiers
Taking on a unit in a converted building or a high-street parade often means fitting out from an empty shell. We can price and deliver the electrical fit-out — power, lighting, containment and a compliant distribution board — as one job rather than a series of separate call-outs.
Frequently asked questions
Yes. We handle both stages — first-fix containment, cabling and rough-in while the shell is open, and second-fix fittings, terminations and finishes once the space is lined out — on converted industrial units and new-build commercial ground floors alike.
Yes. Running new sub-mains and distribution into a building that was never designed for its current commercial use is routine work for us — from the incoming supply through to distribution boards serving individual units.
A full test and inspection certificate for the installation, schedules of test results, and as-installed information — the pack a landlord, managing agent or building control officer will ask to see before a unit is signed off.
Yes. We work to a main contractor's programme as the electrical subcontractor, attending progress meetings where needed, sequencing our fix stages around other trades, and delivering our section of the handover pack in the format the contract requires.
