Electrical work across London
London is one of the four areas we regularly work across, alongside Hertfordshire, Bedfordshire and Cambridgeshire. We're based in Stevenage, with journey times into London depending heavily on the time of day and route.
Traffic into London is unpredictable, so we don't promise a fixed arrival time. The phone line is open 24 hours and timing is agreed with you once we know the location and the job.
Our London work tends to lean commercial, including larger installations and LV panel board work for warehouses and industrial units, which fits the scale of projects where our team expands beyond our core group. We also take on domestic jobs, from period conversions and terraces to flats in newer developments, right across the city's boroughs.
Typical London jobs include commercial fit-out electrics, LV panel board installation for larger sites, fuseboard upgrades in older converted properties, EV charger installs, and EICRs for the capital's large rental and leasehold market.
Within London we see real variation borough to borough, from Victorian terraces and mansion blocks in the inner boroughs to warehouse conversions, modern apartment blocks and purpose-built commercial units further out. Managing agents and letting agents often need quick turnaround on EICRs between tenancies, while commercial clients may need out-of-hours access for electrical work in occupied buildings. We try to be straightforward about what's realistic given London's traffic and parking restrictions, rather than promising something we can't reliably deliver on the day.

Common local issues
Common electrical issues in London
London's older housing stock, dense conversions and commercial density create a distinct set of recurring electrical issues, many of them tied to how buildings have been altered and reused over the decades.
Ageing wiring in converted properties
Many London flats sit within older Victorian or Edwardian buildings that have been converted over the years, often leaving a mix of old and new wiring that needs careful assessment.
Overloaded or outdated fuseboards
Older consumer units in period conversions are often undersized for modern appliance use, increasing the risk of nuisance tripping or worse, particularly where a kitchen or bathroom has been added since the original installation.
Leasehold and rental compliance
London's large rental and leasehold market means landlords and managing agents regularly need up-to-date EICRs to meet their obligations, and we can work around tenant move-out and move-in dates where timing is tight.
Commercial fit-out changes
Units change tenants frequently in London, and incoming businesses often need electrical updates to match a new layout or increased load.
Space constraints on EV charging
Installing EV chargers in London often means working around on-street parking, shared driveways or limited space, which needs a proper site assessment.
