Consumer Unit Upgrade in Guildford
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 Guildford, that covers Onslow Village, Merrow, Burpham, Stoughton, Westborough, Charlotteville, Shalford. Guildford is Surrey's county town, with a historic cobbled High Street, a substantial university population, and residential areas ranging from Victorian terraces near the centre to larger detached houses in the surrounding hills, close to the North Downs and Surrey Hills.

FAQs
Consumer Unit Upgrade in Guildford: FAQs
Do you provide consumer unit upgrade across all of Guildford?
Yes, we cover the GU1, GU2, GU3 and GU4 postcode areas in full, including Onslow Village, Merrow, Burpham, Stoughton, Westborough, Charlotteville, Shalford.
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.
Are there conservation areas across Guildford?
Yes, several, including the historic town centre and parts of some residential neighbourhoods. We check the position for your specific address as part of the feasibility assessment.
