The company runs a supply from the house, fits lights and sockets inside, then tests the finished installation and issues the documents it needs. ## Outbuilding and summerhouse electrics prices Outbuilding and summerhouse electrics start from £450. Distance from the house, the number of lights and sockets, and a fuse board inside the building all change that starting price. - Outbuilding / summerhouse electrics: from £450 - Starting prices, not a fixed figure for every shed or summerhouse. - The written price follows the run from the house, the circuits inside, and any fuse board in the building. - Cable, fittings, testing and documents for this installation sit in that quote. ## Power for a summerhouse or shed A shed, summerhouse or garden room needs this work when lights, sockets and a supply from the house replace an extension lead. - **A summerhouse used after dark:** You want lights and a heater or kettle inside, without running a lead from the kitchen. - **A workshop shed:** Tools, chargers and a radio need sockets on a protected circuit, not a reel on the grass. - **A garden room desk:** A laptop, lamp and monitor need sockets in the building and a tested supply from the house. - **A garden studio for tenants:** A garden studio for tenants needs lights, sockets, testing and documents, not a temporary lead. ## What is covered The installation covers the supply into the outbuilding or summerhouse, the lights and sockets inside, and the testing and documents that work needs. ### Included - A supply from the house into the shed, summerhouse or garden room - Lights and sockets inside the building - A fuse board in the outbuilding when the circuits need one - Testing of the new work - The installation documents the job requires ### Not included - The shed or summerhouse building itself - Joinery, decorating or flooring inside the garden building - Path lights and spikes away from the building, which sit under garden and outdoor lighting ## What happens on the day TMB Electrics isolates the house board while the new supply is connected, fits the interiors, then tests and hands over the documents. 1. **Arrival at the house:** TMB Electrics walks from the house board to the garden building, isolates that board for the new supply, and protects floors and lawn. 2. **Fitting the supply and interiors:** A supply is run into the outbuilding, then lights, sockets and any fuse board inside are fitted and connected. 3. **Testing and the certificate:** The new circuits are tested, power is restored, and you are given the installation documents for the job. ## What you get You leave with power inside the building, documents for the installation, and no extension lead across the garden. - **Power in the building:** Lights, sockets and appliances in the shed or summerhouse run from circuits inside that building. - **A documented installation:** You keep the test results and the certificate for the new supply and the fittings inside. - **No trailing lead in the garden:** The supply is a fixed installation, so an extension lead is not left across the lawn. ## Outbuilding and summerhouse electrics questions Homeowners ask about cost, the fuse board, power in the house, and the certificate before putting electrics in a summerhouse. ### How much do outbuilding electrics cost? Outbuilding and summerhouse electrics start from £450. A longer cable run from the house or extra lights and sockets inside raises the written price. Book Online for the figure that applies to your building. ### Can you put lights and sockets in a shed? Yes, TMB Electrics puts lights, sockets and a supply from the house into sheds, summerhouses and garden rooms. The circuits are tested at the end of the job. You keep the installation documents. ### Do I need a consumer unit in the summerhouse? A consumer unit, the fuse board, goes in the summerhouse when that building needs its own circuits and protection. A short supply with a small load can come from the house fuse board. The written price names which arrangement the job uses. ### Does the house lose power during the work? The house fuse board is isolated while the new supply is connected. Power to the rest of the house returns once that connection is tested. Fitting work inside the garden building does not keep the house off. ### What certificate do I get for summerhouse electrics? You get the testing and the installation documents the job requires. New circuits are recorded as installation work, and TMB Electrics is Part P certified for notifiable work. Smaller additions can use minor works certification from £80. ## Business facts - Service area: Banstead, Sutton, Wallington, Reigate, Purley, Epsom, Kingswood, Coulsdon, Tadworth, Ewell, Horley, Burgh Heath, Chipstead, Worcester Park, Ashtead - Hours: Every day 00:00–23:59 - Phone: +447460070551 - Email: trevor@tmbelectrics.co.uk ## Book Online - [Book Online](https://www.tmbelectrics.co.uk/#chat): Send the job details and postcode to TMB Electrics. ## Related pages - [Full sitemap](https://www.tmbelectrics.co.uk/sitemap.md): Complete machine-readable page directory.
