See published prices and what is included. Cooker and oven connections, electric showers, extractor fans and immersion heater repairs. ## What appliance work costs Each published price assumes a suitable circuit already exists in the right place. Where the appliance needs more current than the existing circuit can carry, a new circuit is surveyed and priced separately. - Cooker or oven connection: £120 - Electric shower installation: £220 - Extractor fan installation: £180 - Immersion heater repair: £70/hr - Quotes are free and there is no call-out charge. - Electric showers and cookers often need their own circuit, which is confirmed before the work is agreed. - A certificate is issued for the work carried out. - Plumbing connections for showers are not included and are handled by a plumber. ## The circuit decides the job The appliance is rarely the hard part. Whether the existing circuit can feed it is. - **Cooker and oven connections:** A freestanding cooker or built-in oven connected at a cooker control unit, on a circuit rated for its load. - **Electric showers:** High current draw, so almost always a dedicated circuit with its own protection. - **Extractor fans:** Bathroom fans have specific rules on zones, isolation and overrun that decide where switching goes. - **Immersion heaters:** Usually a repair rather than an install: failed element, failed thermostat or a tripping circuit. ## What the work covers The quote assumes a suitable existing circuit and says so where a new one is needed. ### Included when agreed - Checking the existing circuit is suitable for the appliance - Connecting the appliance and its isolation - Testing the circuit after connection - A certificate for the work carried out - Taking the old unit away where you want that ### Not included automatically - New circuits back to the consumer unit, priced after survey - Plumbing work, including shower water connections - Supplying the appliance itself - Building work, tiling or making good ## How the visit works A photo of the existing connection point and the appliance rating plate settles most of this in advance. 1. **Check the rating and the circuit:** The appliance load is compared against what the existing circuit can carry. 2. **Confirm before starting:** If a new circuit is needed you hear that before work begins, not afterwards. 3. **Connect and test:** The appliance is connected, isolated correctly and the circuit tested. 4. **Demonstrate and hand over:** You are shown the isolation point and given the certificate. ## What you are left with Correct protection matters more than the connection itself on these circuits. - **A properly fed appliance:** On a circuit rated for what it actually draws. - **Accessible isolation:** You can turn it off safely without going to the consumer unit. - **Certification:** Paperwork covering the connection. ## Appliance connection questions Clear answers before you request a quote. ### Can I connect a cooker to a normal socket? Some smaller ovens are supplied with a plug and can. Most freestanding cookers draw far too much and need a dedicated circuit at a cooker control unit. ### Does an electric shower need its own circuit? Almost always. They draw a lot of current and sharing a circuit is not acceptable. ### Do you do the plumbing for a shower? No. The electrical supply, isolation and testing are covered; the water connection is a plumber's work. ### My immersion heater trips the electrics. Is that the element? Often, but not always. Testing separates a failed element from a thermostat fault or a problem on the circuit. ### Where does a bathroom fan isolator have to go? Outside the bathroom zones, and the switching arrangement depends on whether the fan has a timer overrun. That is set out at the visit. ### Can you replace like for like quickly? Yes, where the existing circuit is suitable. That is confirmed first rather than assumed. ## Business facts - Based: 12 Rangoon Close, Colchester, CO2 9RH - Service area: Colchester, Witham, Maldon, Wivenhoe, Tiptree, Kelvedon, West Mersea, Stanway, Brightlingsea, Coggeshall, Marks Tey - Hours: Mon, Tue, Wed, Thu, Fri 09:00–17:00 - Phone: +447414545781 - Email: team@lightingelectrical.co.uk ## Request a quote - [Start a request](https://lightingelectrical.co.uk/#chat): Send the job details and postcode to Lighting Electrical. ## Related pages - [Socket and switch installation](https://lightingelectrical.co.uk/services/sockets-and-switches): Sockets and switches in Colchester. - [Fuse board replacement](https://lightingelectrical.co.uk/services/fuse-board-replacement): Fuse board replacement in Colchester. - [Electrical Fault Finding & Repair](https://lightingelectrical.co.uk/services/electrical-fault-finding): Electrical fault finding in Colchester. - [House Rewiring](https://lightingelectrical.co.uk/services/house-rewiring): House rewiring in Colchester. - [Full sitemap](https://lightingelectrical.co.uk/sitemap.md): Complete machine-readable page directory.
