Consumer Unit Upgrade in East Grinstead
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 East Grinstead, that covers Ashurst Wood, Forest Row, Dormans Park, West Hoathly, Felbridge, Turners Hill, Imberhorne. East Grinstead's High Street is one of the best-preserved medieval streets in Sussex, lined with timber-framed and Georgian-fronted buildings, while the wider town includes Victorian terraces, 20th-century suburbs and newer estates. The town sits close to Ashdown Forest and the Weald countryside that gives the region its name.

Consumer Unit Upgrade in East Grinstead: FAQs
Do you provide consumer unit upgrade across all of East Grinstead?
Yes, we cover the RH19 postcode area in full, including Ashurst Wood, Forest Row, Dormans Park, West Hoathly, Felbridge, Turners Hill, Imberhorne.
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.
Can I extend a listed building in East Grinstead town centre?
Listed buildings require listed building consent for alterations that affect their character, in addition to any planning permission needed. We assess this on a case-by-case basis and can advise on the likely process.
