Cost to Rewire a House in the UK (2026 Guide)
.jpg "Cost to Rewire a House in the UK (2026 Guide)")
If you've just moved into an older property — or your electrician has flagged concerns during a routine inspection — the question on your mind is probably the same one thousands of UK homeowners search every month: how much does it cost to rewire a house?
In short, there is no one price for rewiring. The cost depends on things like the size of the property and the state of the current wiring. Instead, we'll give you current price ranges so you know what to expect before you call.
Estimated Cost to Rewire a Property in the UK
Based on the size of the property, here is a rough breakdown of the costs of rewiring a home in 2026. These aren't set prices; they're ranges based on what the market usually charges.
⚠️ Disclaimer: These are just rough estimates; costs can vary a lot depending on the size, condition, accessibility, and location of the property.
In the southeast, where labor is more expensive, the cost of rewiring a house in Brighton or East Sussex may be on the higher end of these ranges.
What Determines the Cost of Rewiring a Home?
Understanding what drives the price helps you budget more accurately — and spot quotes that seem too good to be true.
Property Size and Number of Rooms
The more rooms, circuits, sockets, and lights that need rewiring, the higher the labour and materials cost. A 4-bedroom house with multiple floors simply requires more time and cable than a compact 1-bedroom flat.
Age and Condition of Existing Wiring
Older properties — particularly those built before the 1970s — often have rubber-insulated or lead-sheathed wiring that needs to be completely replaced. If your property still uses an outdated fuse board with rewirable fuses, it’s often a clear sign that a full rewire may be needed.
Accessibility
If cables need to be run through solid walls, under concrete floors, or in properties with limited loft space, expect additional time and cost. Properties with easy access to joists and floorboards are generally quicker and cheaper to rewire.
Location and Labour Costs
Rates can differ depending on where you are in the UK. Electricians in London and the South East — including Brighton, Hove, and surrounding areas of East Sussex — typically charge higher day rates than those in the North or Midlands. This reflects local living costs and demand, not necessarily skill level.
Additional Work Required
If your rewire uncovers issues like a failing consumer unit, inadequate earthing, or the need for additional circuits (for an EV charger or a new extension, for example), costs will increase. Decoration work to make good after cables are chased into walls is also often excluded from the electrical quote.
What Does Rewiring a House Involve?
A full electrical rewire means replacing all the wiring throughout your home — not just swapping a few sockets. Here's what the process typically includes:
- First fix: Cables are run throughout the property. This usually involves lifting floorboards, chasing walls, and drilling through joists. It can be disruptive — think dust and temporary mess.
- Consumer unit replacement: Your old fuse box is swapped for a modern consumer unit (fuseboard) with RCD protection.
- Second fix: Final fittings such as sockets, switches, lights, and the consumer unit are installed and connected.
- Testing and certification: The completed system must be inspected and tested by a qualified electrician, who will then provide an Electrical Installation Certificate (EIC) in line with BS 7671 regulations.
The whole process needs to be carried out by a Part P-registered electrician, who will notify the local authority on your behalf. For a more detailed breakdown, see our guide to the stages of rewiring a house.
How Much Time Is Needed for a Full House Rewire?
A standard full rewire generally takes between 5 and 10 working days, with timing depending on the home’s size and structure.
- 1–2 bedroom property: 3–5 days
- 3-bedroom house: 5–7 days
- 4-bedroom house: 7–10+ days
During first fix, the property is generally not liveable, so it's worth planning ahead — especially if you're rewiring as part of a renovation.
Can You Rewire a House in Stages?
Yes — and for many homeowners, this is a practical option. If money is an issue, you can rewire a house in stages, starting with the most important circuits (like the kitchen or consumer unit) and finishing the rest later.
However, there are trade-offs. A staged rewire is usually less cost-effective overall because the electrician will have to come back and set up multiple times.
How to Tell Your House Needs Rewiring
Unsure whether your home needs rewiring? Look out for these common warning signs:
- Frequent tripping of the fuse board or circuit breakers
- Flickering or dimming lights with no obvious cause
- Burn marks or discoloration near sockets and switches
- Older round-pin outlets or a fuse box using traditional fuses rather than circuit breakers (MCBs)
- Rubber, fabric-covered, or lead-sheathed cables (visible in the loft or under floorboards)
- Persistent burning smell with no identifiable source
- The property hasn't been rewired in 25–30+ years
If you're buying an older property, always ask for a recent Electrical Installation Condition Report (EICR). If one isn't available, commission one before exchange.
Is Rewiring a House a Big Job?
In simple terms, rewiring a house is no small task. It's not a weekend project, and it's not something you can do yourself legally (domestic electrical work must be notified and certified under Part P of the Building Regulations).
That said, careful planning makes the process much easier to manage. Most homeowners find it easier to rewire during a broader renovation when walls are already open and the property is empty. If you're living in the property, expect some disruption — but a good electrician will work methodically to minimise it.
On the plus side, a completed rewire typically lasts for decades without issues.
Can Rewiring a House Increase Property Value?
- Remove a red flag that could put off buyers or mortgage lenders
- Pass an EICR — increasingly required by landlords, lenders, and conveyancers
- Make your home insurable without caveats
- Open the door to modern additions like EV chargers, smart home systems, or solar battery storage
Think of it less as a value-add and more as protecting the value you already have.

Rewiring FAQs
How much can you expect to pay to rewire a house in the UK?
For most UK properties, a full rewire costs between £1,500 and £9,000+, depending on the number of bedrooms, the property's condition, and your location. Always get multiple quotes from Part P-registered electricians.
How much to rewire a 3 bed house?
For a typical three-bedroom property, rewiring costs in the UK often range from £3,500 to £6,000. Properties in areas like Brighton or East Sussex may be at the higher end of this range due to regional labour rates.
How much to rewire a 4 bed house?
Expect to budget between £5,000 and £9,000 or more for a 4-bedroom house rewire, particularly if the property is older or has limited accessibility.
What’s the typical timeframe for rewiring a home?
For most homes, the process is completed in roughly 5 to 10 working days. A smaller 1–2 bedroom property may be completed in 3–5 days, while a larger 4-bedroom home can take 7–10 days or more.
Is it possible to rewire a house while still living in it?
Yes, though it's disruptive — particularly during first fix when floorboards are lifted and cables are run. Many homeowners choose to temporarily move out during the most intensive phase.
How much is a house rewire if I only do part of it?
A staged rewire is possible, but costs vary widely depending on which circuits are prioritised. If you want to save money, it's usually better to do the work all at once. Talk to your electrician about it before you move forward.
Does rewiring a house add value?
A rewire rarely adds a headline figure to your property's sale price, but it removes a significant red flag for buyers and lenders, ensures compliance with current wiring regulations, and protects the long-term value of your home.
Final Thoughts
In the UK, rewiring a house is a big investment, but it's usually needed for older homes. Whether you're buying a Victorian terrace in Hove, fixing up a semi-detached in East Sussex, or just dealing with an old fuseboard, getting the electrical wiring right will keep your family, your home, and your peace of mind safe.
The key takeaway: don't cut corners on who you hire. Cheap quotes can mean uncertified work, poor materials, or a job that fails its EICR at the worst possible time. Choose a registered, experienced domestic electrician, get at least two or three quotes, and ask to see certification on completion.
