How Much Does It Cost to Rewire a House in the UK?

Old or faulty wiring isn’t just inefficient; it can be dangerous, increasing the risk of shocks and house fires.

Naturally, one of the first questions homeowners ask is: “How much does it cost to rewire a house in the UK?”

In this guide, the expert electricians at Duravault explain the key factors that affect rewiring costs, provide typical price ranges, and highlight why it’s essential to get the job done by a qualified professional.

Why Rewiring Is Important

Wiring in UK homes is expected to last around 25–30 years before it needs upgrading. If your property hasn’t been rewired in that time — or you’re unsure of the wiring’s age — it may not meet current safety standards.

Old wiring can lead to:

• Flickering or dimming lights
• Regularly blown fuses or tripped RCDs
• Burning smells from sockets
• Increased fire risk

Factors That Affect the Cost of Rewiring

Several factors determine the price of a house rewire:

1. Property Size

The larger the property, the more circuits, sockets, and wiring are needed.

• 1-bedroom flat: from £3,000–£5,000
• 3-bedroom semi-detached house: from £5,000–£8,000+
• 5-bedroom detached house: £8,000+

2. Accessibility

If the property is occupied and fully furnished, it takes longer to access wiring, which increases labour costs. An empty property is quicker (and cheaper) to rewire.

3. Age and Condition of Existing Wiring

Older homes may require additional work to remove outdated cabling or to make the installation compliant with modern safety regulations.

4. Consumer Unit Upgrade

A rewire almost always includes upgrading to a modern fuse box with RCD protection for added safety.

5. Additional Installations

If you want extra sockets, downlights, USB outlets, or outdoor lighting added during the rewire, these will increase costs but add value and convenience.

Typical Rewiring Costs in the UK (2025)

To give homeowners a ballpark figure, here are the average costs for a full house rewire:

• 1-2 bedroom flat: £3,000–£5,000
• 3-bedroom house: £5,000–£8,000+
• 4-bedroom house: £6,000–£8,000+
• bedroom house: £7,500–£10,000+

These prices include materials, labour, and a new consumer unit.

How Long Does a Rewire Take?

• 1-2 bedroom flat: 5–7 days
• 3-bedroom house: 7–10 days
• 4-5 bedroom house: 10–14 days

Work is usually done in two stages:

• First fix – replacing wiring, sockets, and switches (before plastering/decoration).
• Second fix – fitting lights, switches, and consumer unit.

Signs Your House May Need Rewiring

You should consider a rewire if:

• Your electrics are over 25 years old
• You have an outdated fuse box without RCD protection
• There are two-pin sockets still in use
• You notice burning smells, buzzing, or sparks
• You haven’t had an EICR (Electrical Installation Condition Report) in the last 10 years

👉 Book an EICR to find out if your home needs rewiring.
