House Rewiring - Full & Partial
If you live in Horley, Redhill, Reigate, Crawley or the surrounding Surrey and West Sussex area, you may be wondering whether your home needs rewiring - and what that actually involves. Rewiring isn't just a safety requirement, it modernises your home, adds value, and ensures your electrics meet current UK regulations. We carry out full and partial rewires across the region, from initial assessment through to certification.
Do You Need a Rewire?
Most homes built before the 1970s should be checked. Electrical systems generally need upgrading every 25-40 years, or sooner if the wiring is damaged or unsafe. Many properties in Crawley Down, Smallfield, Horley and Outwood were built decades ago and may still contain outdated wiring or older fuse boards - homes in areas like Reigate, Dorking and East Grinstead with older wiring (pre-1980s) often need more extensive work.
Common signs a property needs rewiring include old round-pin sockets, frequent tripping or blown fuses, and an EICR that's flagged unsatisfactory results.
Full vs Partial Rewire
A full rewire replaces all the cabling, accessories (sockets, switches, light fittings) and the consumer unit in a property, bringing the entire installation up to current BS 7671 18th Edition Wiring Regulations. It's the right choice for older properties that haven't been touched in decades, or as part of a full refurbishment.
A partial rewire addresses specific circuits, rooms or areas that need updating - a kitchen or bathroom being modernised, an extension being added, or a section of wiring that's failed inspection - without disturbing the rest of the property's electrics. This is often the more practical and cost-effective route where the wider installation is still sound.
Housing stock within areas of Crawley, Horley and across Surrey and Sussex ranges from 1950s and 1960s new-town properties through to modern developments. The older the property and the longer since it was last rewired, the more likely it is to need attention. Common warning signs include:
A fuse box with old rewireable fuses rather than modern circuit breakers
Black rubber, fabric or lead-sheathed cabling - signs of wiring decades old
Round-pin sockets, or sockets mounted in skirting boards
Recurring tripping, flickering lights or a burning smell
Discoloured or warm sockets and switches
No RCD protection on the consumer unit
If your property shows any of these, an EICR inspection is the right first step - it confirms the condition of the installation and whether a full or partial rewire is needed.
What It Costs
Full house rewire - from £4,500, subject to a site survey. Prices vary depending on the age of your property, access to cabling, plaster depth, and whether the property is occupied during works. We always confirm a fixed price after a quick survey, before any work begins - no hidden costs, no surprises.
What to Expect
Rewiring isn't a quick job - it requires careful planning and skilled electricians. A full rewire typically takes between 5 and 10 days, depending on the size of the property and the condition of the existing installation. We'll assess your property before work begins, give you a clear timeline, and advise in advance on what to prepare for, keeping disruption to a minimum throughout.
Why It's Worth Doing
Rewiring ensures reduced risk of electrical fires or faults, compliance with current safety standards, the ability to support modern appliances and technology, and improved property value. Modern, safe wiring is a strong selling point for buyers and a factor insurers and mortgage lenders look favourably on.
