London's older housing stock, especially Victorian terraces and 1930s semis in boroughs such as Lambeth and Southwark, often has outdated radial circuits and consumer units that cannot safely carry new electric heating loads. Adding storage heaters or panel systems without first checking earthing and upgrading boards leads to repeated trips or worse. We always start by tracing the existing wiring back to the incoming supply before any new circuits are run.
Winter damp from the Thames and frequent temperature swings around freezing mean condensation inside lofts and behind skirtings can corrode connections within a season. In these conditions we use moisture-resistant cable and IP-rated accessories even on indoor runs. Properties built on the old river gravels around Waterloo also sit slightly lower, so we route cables above floor level where possible to avoid future water ingress during heavy rain.
Part P of the Building Regulations requires notification for most new circuits in dwellings. We complete the necessary paperwork and leave the homeowner with the certificate on the same visit. In flats above shops or in converted warehouses common near London Bridge, we also coordinate with building management to avoid shared riser conflicts that can delay a job by days.
Night callouts often involve failed night-storage heaters whose bricks have cracked after years of cycling. We carry replacement elements and thermostats in the van so the system can be returned to service before dawn without a second visit.
Technician insight
In London, the thing that catches most people out with 24/7 electric heating installer is the state of the wiring in pre-1960s terraces around Westminster and Southwark. Damp has often worked its way into junction boxes behind the old plaster, so what looks like a simple heater swap turns into tracing and replacing whole runs before the new system can be connected safely.
Storage Heater Failure in Waterloo
A top-floor flat in a 1950s block near Waterloo Station lost all heating on a January night. We found two storage heaters with failed elements and a consumer unit that was already at capacity. We replaced the elements, added a small dedicated circuit and left the system running before the morning commute.
How it works
- 1
Phone Assessment
We ask about the property age, existing heating type and any recent electrical work so we arrive with the right parts and tools.
- 2
On-Site Inspection
We test the consumer unit, earthing and existing circuits before confirming the exact scope of the electric heating installation.
- 3
Installation Work
New cables are run, heaters mounted and controls wired in, always leaving the system safe to energise at each stage.
- 4
Testing And Handover
Full electrical tests are carried out, the installation is commissioned and the customer receives operating instructions and paperwork.
Pricing
Upfront quotes are given after the site visit and before any work starts.
