Temporary Builders Supply Through to Permanent Connection: The Full Process

Temporary builders supply gives a construction site safe power until the permanent connection is ready; the move to permanent involves installing consumer mains and the final meter position, cutting over from the temporary supply, and lodging the CCEW and NOSW before the temporary pole or pillar is removed. Both stages involve network work, so they need a Level 2 ASP electrician.

Planning the temporary and permanent supply together is the simplest way to avoid delays at occupation certificate and handover.

Stage 1: What should be planned before the build starts?

Decide where the permanent meter box will go and how the permanent supply will reach it, overhead or underground, before you place the temporary supply. Siting the temporary pole or pillar where it will not block excavation, slabs or scaffold saves relocating it mid-build. The network application should cover the final connection requirements, including maximum demand and whether three-phase is needed.

Stage 2: What does a compliant temporary supply include?

• A temporary pole or pillar suitable for the site and the network's requirements.
• A lockable meter enclosure and main switch.
• RCD-protected outlets for tools and site sheds.
• Correct earthing, labelling and weather protection.

For multi-dwelling projects, see temporary builder supply for duplexes and triplexes.

Stage 3: What is installed for the permanent connection?

During fit-off, the permanent meter box, main switchboard and consumer mains are installed. Underground mains are laid in conduit, or an overhead point of attachment is fitted. Everything is inspected and tested before cut-over.

Stage 4: What happens at cut-over?

1. The Level 2 ASP books and performs the disconnection of the temporary supply.
2. The metering is moved or a new meter is arranged at the permanent position.
3. The permanent mains are connected to the network.
4. Polarity, insulation and RCD tests are completed and power restored.

Where builders still need site power after cut-over, outlets can be supplied from the permanent board.

Stage 5: What paperwork and clean-up is needed?

The CCEW is issued for the installation and the NOSW lodged with the network. The temporary pole or pillar is then removed. Keep all certificates for the occupation certificate, the owner's handover pack and the new owner's records.

What causes delays and how do you avoid them?

• Late network applications. Apply as soon as plans and demand are known.
• Meter box position changes late in the build.
• Retailer and metering bookings not made in time.
• Temporary supply placed where it blocks works.
• Using separate contractors for temporary and permanent, causing gaps between bookings.
