Temporary site power installation in South Croydon gives builders safe electricity from day one. We set up site supplies, distribution boards and 110V outlets, test them and remove them when the job ends.

Building sites are tough on cables and tools, and that raises the risk of shocks. Reduced low voltage systems step mains power down to 110V, which is far less dangerous if something goes wrong, and are the recommended choice for portable tools on construction sites.
A typical temporary supply has a weatherproof site distribution board, RCD protected 230V outlets for items that need them, 110V transformers or outlets for tools and temporary lighting for dark areas. Everything is chosen to survive weather, dust and knocks.
Temporary installations are tested before use and should be inspected regularly while work continues, because damage happens quickly on site. We can carry out these checks on a schedule that suits the length of your project, and update the paperwork each time.
Tell us the size of the site, the tools and equipment you'll run and how long the project will last. We check where the supply will come from, whether that's an existing building or a builder's supply from the network operator, and plan the layout around your work areas.
We install the site board, outlets and any temporary lighting, test the system and give you the certificate before your trades start using it. When the build is finished, or the permanent supply is ready, we disconnect and remove the temporary installation safely.
Call or send a message about the job. For urgent faults we aim to respond the same day, with no call-out charge.
An electrician comes out, checks the job and talks you through the options, then you get a free, no-obligation quote.
When the work is finished, we test everything we've worked on and hand over the right certificate for the job.
Yes. We set up temporary supplies for new builds, extensions and refurbishments, from a single site board to power spread across a larger site. We work with your builder on where outlets and lighting are needed, and adjust the setup as the build moves on.
On a new build with no existing supply, usually yes. You apply to UK Power Networks for a temporary builder's supply, and we connect the site board to it. On renovations, we can often take temporary power from the existing installation instead.
Temporary electrical installations on construction sites should be inspected and tested at least every three months, and more often on busy or harsh sites. Leads and tools also need regular checks. We can schedule inspections for the length of your project.
Sometimes the same incoming supply is used, but the temporary site board and outlets are removed. Once the building is ready, we install the permanent consumer unit and circuits, test them and take the site equipment away, so the handover to the owner is clean.
