Why a London electrician makes a difference
Regular work across South London, from flats in SE10 to homes in SW19. Domestic and commercial jobs both covered, including out-of-hours work for businesses.
Regular work across south London
JMO Electrical works throughout south London from a base in Purley, on the southern edge of the capital. Jobs run from flats in the south east through to homes and small commercial premises in the south west, with the Croydon and Sutton corridors in between covered daily.
Standard hours are 8:00am to 5:30pm and emergency call-outs are available 24/7. For commercial customers, evening and weekend working is normal rather than exceptional, a shop or office rarely wants its power isolated at eleven on a Tuesday morning.
London property types we work on
South London's stock is dominated by Victorian and Edwardian terraces, many of them long since split into flats, alongside inter-war suburbia, post-war blocks and recent new-build apartments. Each has a distinct electrical profile.
Converted terraces are the most demanding: two or three separate installations sharing one original service head, landlord supplies for communal lighting, meters in cupboards nobody has a key to, and cable routes that cross demises. Purpose-built blocks bring risers and landlord circuits; new-build flats bring small boards with no spare ways and surface finishes that make additions awkward.
What London calls us out for
Fault finding and emergency attendance, EICRs for landlords and managing agents, consumer unit upgrades in flats and conversions, commercial lighting and small power, and periodic inspection for insurers.
Full rewires are more often partial here, a flat, a floor, or the circuits that testing has actually condemned, because a whole-building rewire in a converted property needs the freeholder as well as the occupier on board.

Local issues
Electrical problems we see most in London
Property age, building fabric, weather and infrastructure all shape what goes wrong here.
Converted houses and shared supplies
The single most common complication in south London is the converted house. One original service head now feeds two or three flats plus a landlord supply, often through cables added at different times by different contractors, with no labelling and no records.
Before any board work or testing, we establish what belongs to which demise. Getting that wrong is how people end up isolating a neighbour's freezer or certifying circuits that are not theirs.
- Unlabelled boards feeding circuits in another flat
- Communal lighting and door entry on a landlord supply nobody maintains
- Meter cupboards with restricted or lost access
- Bonding to incoming services missing or shared incorrectly
Old terraces, high loads and tight routes
Victorian terraces were designed for a lightbulb per room. They now run induction hobs, showers, home offices and sometimes an EV. The wiring has usually been extended in stages to keep up, which produces long spur chains and overloaded circuits.
Solid brick walls, shallow voids and lath and plaster ceilings also limit routes, so good work in these properties is as much about planning where cable can go as about design on paper.
Commercial premises and continuity of trading
For a shop, salon, café or office, the cost of an electrical job is rarely just the invoice, it is the trading hours lost. That is why inspection, board changes and lighting replacements here are so often done in the evening or at the weekend.
We agree the isolation window in advance, work to it, and leave the premises able to open on time. Certification and any remedial recommendations follow in writing so insurers and landlords are satisfied.
Compliance pressure in the rented sector
London landlords and agents work to hard deadlines: five-yearly EICRs, 28 days to complete required remedials, and evidence required at the start of a tenancy. Reports that arrive late create real problems.
We turn reports around quickly and split compulsory C1 and C2 items from C3 recommendations on the quote, so nobody is charged for improvements they were never obliged to make.

Which parts of London do you cover?
South London principally, working out from our Purley base across the southern boroughs for both domestic and commercial jobs.
How quickly can you reach south London?
Purley sits on the southern edge of the capital, so most of south London is a straightforward run. Jon will give you a realistic time when you call.
How much does an electrician cost in London?

Yes, 24/7 for dangerous faults: loss of power, burning smells, scorched accessories and damaged cable. The installation is made safe before any repair is priced.
