Your Local Temporary Site Electrics Team In Bromley
Bromley is home for us. Our office is on Hastings Road, BR2, so when a Bromley site needs temporary power, safe and ready when the trades arrive, we are minutes away rather than a long haul across London. That local base matters most when something changes on site or a supply needs attention out of hours.
GPM London has been installing temporary site electrics across Bromley and South East London since 2014. We cover the full range here, from a tidy supply for a single residential extension to phased distribution for a town-centre commercial fit-out, all signed off to the standards your principal contractor and insurer expect.

The Kind Of Bromley Sites We Power
Bromley has one of the busiest town centres in South East London, and it keeps changing. Regeneration around the High Street, Market Square, St Mark’s Square and The Glades brings a steady run of commercial and mixed-use fit-outs, while the surrounding roads see constant residential extensions, loft conversions and refurbishments. Town-centre jobs often mean tight access, shared servicing and public footfall to work around, so the supply has to be planned, compact and tidy.
We survey each site first, decide whether a temporary builder’s supply or a generator suits the access and timescale, and set out distribution and lighting that reach the work safely without obstructing the street or neighbouring units. Being based in the town, we reach any Bromley site quickly for setup, changes and call-outs.
Commercial And Town-Centre Sites
Shop and office fit-outs, retail refurbishments and mixed-use developments around The Glades, Market Square and St Mark’s Square. These usually need a metered supply, tidy cable routing and public-access protection while trades are on site.
Residential Sites
Extensions, loft conversions and full renovations across Bickley, Shortlands, Sundridge and the surrounding roads, where a compact, tidy supply keeps a home project moving safely without overloading the existing house electrics.
What We Install On A Bromley Site
- Temporary builder’s supply (TBS): a metered mains connection arranged with the network operator (DNO), sized to the job.
- Generator hook-ups: where the mains is not available or a quick start is needed.
- 110V site distribution: transformers, boards and outlets to the UK reduced low voltage standard for safety.
- RCD-protected distribution: 30mA RCD protection throughout, with cabling kept tidy and clear of walkways.
- Festoon and task lighting: for darker months, deep interiors and internal fit-out areas.
- Inspection and testing: kept compliant with BS 7375 and BS 7671 as the site changes.
Temporary Site Electrics Explained
Temporary site electrics are the safe, temporary electrical supply and distribution installed on a construction or refurbishment site before the permanent connection is in place. They provide reliable construction power for tools, welfare and lighting, delivered through a metered builder’s supply or an on-site generator and distributed at 110V reduced low voltage. On a UK site the installation is governed by BS 7375 and the wiring regulations BS 7671.
What Is Included In A Bromley Site Supply
A GPM temporary supply is a complete package, not just a connection:
| Included | What it covers |
|---|---|
| Temporary builder's supply or generator | The power source, sized and connected for your site |
| 110V distribution | Boards, outlets and transformers for site tools and lighting |
| Site lighting | Festoon and task lighting for safe working |
| RCD protection | 30mA protection throughout the installation |
| Inspection and testing | Compliance to BS 7375 and BS 7671 across the build |
Because we are a full electrical contractor, we can also install and certify the permanent electrics, so you keep one Bromley-based team from the temporary supply through to handover. See our temporary site electrics service and wider commercial electrical work.
What Affects The Cost Of Temporary Site Electrics?
Every site is different, so there is no single price. The cost of a Bromley site supply depends mainly on the size of the site and the load required, the distance to the nearest mains, whether a builder’s supply or a generator is used, how long the supply is needed, and the access on tighter town-centre plots. We give you a clear, itemised quote after a free survey, with no surprises once the job starts.
