If you live in Horley, Redhill, Reigate, Crawley, East Grinstead or surrounding areas in Surrey and Sussex, you may be wondering how much it costs to rewire a house and whether your home or your business needs an electrical upgrade. Rewiring isn’t just a safety requirement - it modernises your home, adds value, and ensures your electrics meet current UK regulations.

Below is a breakdown of typical rewiring costs in Surrey and West Sussex, what affects the price, and how to know if your property needs updating.

Typical Rewiring Costs in Surrey & West Sussex (2025)

1-Bed Flat £2,000 – £3,500

2-Bed House £3,000 – £5,000

3-Bed House £4,500 – £6,500

Homes in areas like Reigate, Dorking and East Grinstead with older wiring (pre-1980s) often require more extensive work.

What Affects the Cost of a Rewire?

1. Property Age & Wiring Condition

Many properties in Crawley Down, Smallfield, Horley and Outwood were built decades ago and may still contain outdated wiring or older fuse boards.

2. Occupied vs. Empty Property

A rewire is significantly faster and cheaper in an empty property especially common for people moving to the area from London.

3. Required Upgrades

Most rewires include a new RCD/RCBO consumer unit, adding £400–£700.

4. Additional Preferences

Local homeowners often request:

Spotlights

Under-cabinet lighting

Smart switches

CCTV/power to outbuildings

Exterior lighting

These increase labour and materials but improve property value.

How Long Does a Rewire Take?

Flats & small houses: 3–5 days

3–4 bed houses: 5–8 days

Larger rural homes (e.g., Burstow, Charlwood): 1–2 weeks

Signs Your Property in Surrey/West Sussex Needs Rewiring

You should consider a rewire if your home has:

Frequent fuse trips

Burning smells or warm sockets

No RCD protection

Old-style rewirable fuses

Black rubber, fabric, or lead-insulated wiring

Fuse board older than 25–30 years

If you’re unsure, an EICR inspection will confirm whether a rewire is required.
