Consumer Unit Upgrade in Sutton
A consumer unit upgrade replaces an old fuse box with a modern unit incorporating RCD (residual current device) protection on relevant circuits, improving safety by cutting power quickly in the event of a fault, and is one of the most common findings recommended on an EICR.
In Sutton, that covers Cheam, Carshalton, Wallington, Belmont, North Cheam. Sutton is a residential outer-London borough with a traditional High Street and well-established suburbs across Cheam, Carshalton and Wallington, offering a mix of interwar family housing and period properties close to Carshalton's historic ponds and village core, within reach of our Croydon and Surrey teams.

Property styles in Sutton
The borough has a strong stock of 1920s and 1930s semis and detached houses across Cheam, North Cheam and Belmont, alongside Victorian and Edwardian houses in the older parts of Carshalton and Wallington. Rear and side-return extensions and loft conversions are common on the semi-detached stock typical of the area.
Planning considerations
Sutton Council (London Borough of Sutton) is the local planning authority. Carshalton village and parts of Cheam and Wallington are conservation areas with a number of listed buildings around the historic ponds, which affects alterations to visible elevations and materials. We confirm the position for individual properties at feasibility stage.

FAQs
Consumer Unit Upgrade in Sutton: FAQs
Do you provide consumer unit upgrade across all of Sutton?
Yes, we cover the SM1, SM2, SM3, SM5 and SM6 postcode areas in full, including Cheam, Carshalton, Wallington, Belmont, North Cheam.
How do I know if my fuse box needs replacing?
Common indicators include old rewireable fuses, no RCD protection, or adverse findings on an EICR. We assess the specific unit on a visit rather than assuming age alone means it needs replacing.
Will I lose power during the upgrade?
Yes, briefly — the supply needs to be isolated while the old unit is removed and the new one connected. This typically takes part of a day and is scheduled with you in advance.
Do you cover Carshalton and Wallington as well as Sutton town centre?
Yes, we work across the SM1, SM2, SM3, SM5 and SM6 postcode areas, including Sutton town centre, Cheam, Carshalton, Wallington and Belmont.
