How Much Does a Full House Rewire Cost in London (2026)?

Rewiring a property is one of the biggest electrical upgrades you can carry out, and in a city like London, costs can vary quite a bit depending on the property and complexity. In 2026, most homeowners are seeing higher prices compared to previous years due to labour, materials, and compliance standards. If you're planning a full rewire, speaking with a qualified Electrician in London early on can help you understand realistic costs and avoid surprises.

On average, a full house rewire in London typically ranges between £5,000 and £9,000, although smaller flats may cost less and larger properties can exceed £10,000.

Cost by Property Size

The size of your home plays the biggest role in determining the final cost. Here’s a general breakdown for London properties in 2026:

• 1-bed flat: £3,000 – £4,800
• 2-bed house: £3,500 – £5,500
• 3-bed house: £5,000 – £8,000
• 4-bed house: £6,500 – £10,000
• 5-bed house: £8,500 – £12,500+

These figures can vary depending on layout, accessibility, and the level of finish required.

What Affects the Cost of a Rewire?

Several factors influence how much you’ll pay for a full rewire in London:

Property condition: Older homes often require more work
Access: Empty homes are quicker (and cheaper) to rewire
Number of rooms: More rooms = more wiring and labour
Specification: Basic vs high-end finishes
Location: Central London jobs usually cost more

Labour is a major part of the cost, and London electricians typically charge more due to demand and overheads.

What’s Included in a Full Rewire?

A complete rewire is more than just replacing cables. It usually includes:

– Removing old wiring
– Installing new cables throughout the property
– Upgrading the consumer unit (fuse box)
– Installing new sockets and switches
– Replacing lighting circuits
– Earthing and bonding upgrades
– Full testing and certification (EICR)

Professional London Electrical Rewiring Experts ensure everything meets current UK regulations and safety standards.

Hidden Costs to Be Aware Of

Many homeowners are caught out by additional costs that aren’t always included in initial quotes:

– Plastering and wall repairs after wiring work
– Upgrading or relocating the fuse box
– Additional sockets or lighting upgrades
– Smart home installations
– Working in occupied properties (adds labour time)

Planning ahead for these extras can help you stay within budget.

Is a Full Rewire Worth the Cost?

While it’s a significant investment, rewiring your home comes with long-term benefits:

– Improved safety and reduced fire risk
– Better performance for modern appliances
– Increased property value
– Compliance with landlord regulations

If your property is over 25–30 years old or showing signs of electrical issues, a rewire is often the safest option.

Final Thoughts

Rewiring costs in London in 2026 aren’t cheap, but they reflect the level of work involved and the importance of safety. Getting a proper assessment from experienced London Electricians is the best way to understand your exact requirements and budget accurately.

If your wiring is outdated or causing issues, don’t wait — investing in a full rewire now can prevent bigger and more expensive problems in the future.
