Every circuit tested, certified and RCD protected." canonical: "https://www.tmbelectrics.co.uk/electrician-sutton/fuse-board-replacement" --- # Consumer unit replacement in Sutton > Fuse board and consumer unit upgrade in Sutton, covering Belmont, Rosehill and the town centre. Every circuit tested, certified and RCD protected. Fuse board and consumer unit upgrade in Sutton by TMB Electrics. Every circuit is tested, protected by an RCD and certified before we leave. ## The cost of a fuse board replacement in Sutton The written price takes in the new metal unit with RCD and surge protection, the labour, circuit testing and the certificate. What moves it is the number of circuits, the condition of the existing wiring and any earthing or bonding the property needs. - Consumer unit (CCU) replacement: from £375 - Defects that testing uncovers on existing circuits are priced separately before any repair goes ahead. - New circuits, such as for an EV charger or a kitchen refit, are priced on their own. - Any earthing or bonding improvement the property needs is quoted first. ## When a Sutton property needs a new consumer unit The fuse board, also called the consumer unit, protects all the circuits in a property. Changing an old one is the biggest safety gain an older Sutton home can make. ### Rewirable fuses and wooden backboards A board that still takes rewirable wire fuses, or sits on a wooden backboard, gives people no RCD protection. Without one, nothing cuts the supply fast enough to stop a shock. ### Breakers without RCDs Plenty of boards fitted in the 1980s and 1990s trip on overload but have no residual current device. Breakers guard the wiring; an RCD guards people. ### Room for new circuits Electric vehicle chargers, electric showers and kitchen refits each need capacity and protection an old board cannot give. A new consumer unit leaves room for all three. ### A C2 on the condition report Landlords fail an Electrical Installation Condition Report when the board is coded C2. A new board clears the code. ## Fuse board replacement for Sutton homes and premises TMB Electrics serves homeowners, landlords and businesses in Sutton, and a board change for any of them follows the same tested and certified process. ### Town centre, Cheam Road and Carshalton Road The service is available for homes and premises around Sutton town centre and along Cheam Road and Carshalton Road, with the supply off for the main part of the visit. ### Belmont and Benhilton A rented home in Belmont or Benhilton can have the board changed and certified, clearing a C2 that would otherwise fail the EICR. ### Rosehill, West Sutton and Sutton Garden Suburb Consumer unit upgrades are available across Rosehill, West Sutton and Sutton Garden Suburb, with the same testing and certification for every one. ## What happens when the board is changed The power stays off for the main part of the visit, which runs between half a day and a full day, with the work in three steps. ### Circuits tested before the swap Each circuit is checked before it goes onto the new board; a fault hiding in the wiring cannot end up tripping the new RCDs. ### The board swap itself The old board is taken out and the new metal unit fitted in its place, with each circuit reconnected and named so you can see what feeds what. ### Live testing and the certificate Once the power is back on, the whole installation is checked live and you are shown round the new board. The certificate follows for your records. ## Why Sutton homes pick TMB Electrics The price is in writing before work starts, circuits are tested before the new board is energised, and Part P notification and the certificate are part of the job. The phone is answered day and night. ## Recent fuse board and electrical work Photos from TMB Electrics jobs show consumer units fitted above meters, neatly dressed conductors, named circuits and surge protection, alongside kitchen downlights and garden lighting at dusk. ## Questions about fuse board replacement in Sutton A Sutton board change runs between half a day and a full day with the power off for the main part, and the certificate is what the home is left with. ### How much is a fuse board replacement in Sutton? The quote in writing takes in the unit itself, the labour, the testing and the certification. Defects found on existing circuits, added circuits and earthing work are priced separately before anything goes ahead. ### How long does a consumer unit change take? Between half a day and a full day. Power is off for the main part of the visit, and all circuits are checked live before you are shown round the new board. ### Does old wiring work on a new board? Each circuit is checked first, and sound existing wiring goes straight onto the new unit. Where testing turns up a fault, the repair is priced on its own first. ### Is a fuse board replacement notifiable? Yes. The work is certified and notified under Part P, and the certificate is issued for your records once testing is done. ### Do I need a new board for an EV charger or electric shower? A new circuit needs capacity and protection an older board does not have, so the consumer unit is replaced first. The charger or shower circuit is a separate job priced on its own. ### What is the difference between a fuse board and a consumer unit? They are two names for the same box. Consumer unit is the current term for the board holding the breakers and RCDs that protect each circuit. ## Areas covered in Sutton The service covers addresses in Sutton town centre and along Cheam Road and Carshalton Road, together with Belmont, Benhilton, Rosehill, West Sutton and Sutton Garden Suburb. ## Other electrical work in Sutton TMB Electrics also undertakes EICRs, full and partial rewires, fault finding, extra sockets, lighting work and EV charge points for Sutton customers. - [Electrician in Sutton](https://www.tmbelectrics.co.uk/electrician-sutton): Sutton electrician for EICRs, fault finding, rewiring, consumer units and EV chargers, with clear next steps before booking. - [Consumer unit replacement (all areas)](https://www.tmbelectrics.co.uk/services/fuse-board-replacement): Fuse board and consumer unit replacement in Banstead and Surrey from £375 by TMB Electrics.
