House Rewire Cost Per Bedroom: 2026 UK Price Guide

A full rewire is one of the biggest electrical jobs a home will ever need, and it is also one of the hardest to price from a distance. The honest answer to "how much does a rewire cost?" is "it depends" — but it depends on a fairly predictable set of factors. In this guide we break down realistic 2026 UK rewire costs by the number of bedrooms, explain why an occupied house costs more than an empty one, and show where a partial rewire can save you money without cutting corners on safety.

All prices below are typical ranges. Your actual quote should always come after an electrician has surveyed the property. For a deeper breakdown of what drives the figure, see our full [house rewire cost guide](/house-rewire-cost/).

What a rewire actually involves

A rewire replaces the fixed wiring throughout your home — the cables buried in walls, ceilings and floors — along with sockets, switches, light fittings, and usually the consumer unit (fuse board). It is done to bring an installation up to the current edition of the wiring regulations, BS 7671 (18th Edition), and to remove old, deteriorating cable that has become a fire or shock risk.

A typical full rewire includes:

• New circuits run in modern PVC twin-and-earth cable
• New back boxes, sockets and switches throughout
• A new consumer unit with RCBO or RCD protection
• Bonding of gas and water services, plus supplementary bonding where needed
• Smoke and heat alarms wired to current standards
• Full testing, certification and notification under Part P

Because this is notifiable work, you should receive an Electrical Installation Certificate and the work must be registered with building control (your NICEIC- or NAPIT-registered electrician handles this for you).

House rewire cost by number of bedrooms (2026)

The single biggest driver of price is the size of the property, which usually tracks the number of bedrooms. More rooms means more circuits, more sockets, more cable runs and more days on site. As a rough 2026 guide for a standard UK home:

• **1-bed flat or small bungalow:** typically £2,300–£3,800
• **2-bed house:** typically £3,000–£4,800
• **3-bed semi or terrace:** typically £3,500–£6,500
• **4-bed detached:** typically £5,500–£9,000
• **5-bed or large/older detached:** typically £8,000–£13,000+

These figures assume a reasonably standard layout. A larger footprint, solid walls that need chasing, awkward access, or a desire for extra sockets and smart wiring will push you toward the top of each band. A simple, modern layout with easy floor access sits lower.

Why the wide ranges? A 3-bed terrace with suspended timber floors and a loft you can stand up in is far quicker to wire than a 3-bed of the same size with solid concrete floors, plastered ceilings everywhere, and no loft access. The labour content — not the materials — is where rewire costs really vary.

Occupied vs empty: why an empty house is cheaper to rewire

Where you can, rewiring an empty property before you move in (or between tenants) is almost always cheaper and faster. There are a few reasons:

• **No furniture to move or protect.** In an occupied home the electrician spends time shifting beds, wardrobes and white goods, then covering carpets and belongings against dust.
• **Floors and walls come up freely.** Lifting carpets, floorboards and skirting is straightforward when nothing has to be put back daily.
• **No working around the household.** In a lived-in home, power has to be juggled so the family still has lighting, a fridge and heating each evening, which slows the job.
• **Faster snagging and making good.** Plastering and decorating after a rewire is much simpler in an empty shell.

As a rule of thumb, expect an occupied rewire to add roughly 15–30% to both the time and the cost compared with the same property empty. If you are buying a house that needs rewiring, getting it done in the gap before move-in day is one of the best-value decisions you can make.

Full rewire vs partial rewire

Not every home needs the whole installation replaced. A partial rewire updates only the circuits that are unsafe or non-compliant — perhaps the upstairs lighting, the kitchen, or the original sockets — while leaving sound, recently installed wiring in place.

A partial rewire can be the right call when:

• A previous owner already rewired part of the house
• One area (often the kitchen or a converted loft) was updated recently
• An EICR has flagged specific circuits as needing remedial work rather than the whole installation

It is usually the wrong call when the cable itself is old rubber- or fabric-insulated throughout, or where mixing old and new circuits would leave the property only partly safe. A good electrician will tell you honestly which applies. If you are unsure whether your home needs the full job, an inspection report is the place to start — our guide on [the warning signs a house needs rewiring](/blog/signs-your-house-needs-rewiring/) covers the red flags to look for.

As a guide, partial rewires often land in the £1,200–£3,000 range depending on how many circuits are involved — cheaper than a full rewire, but only worth it when the remaining wiring is genuinely sound.

What else changes the price

Beyond size and occupancy, several factors move a quote up or down:

• **Consumer unit upgrade.** Most rewires include a new board, but if you only need the fuse board replaced rather than the whole installation, a standalone [consumer unit upgrade](/consumer-unit-upgrades/) typically costs around £450–£900.
• **Plastering and decorating.** Chasing cables into walls means making good afterwards. Some quotes include this; many leave finishing and decorating to you. Always check what "making good" covers.
• **Number of sockets and extras.** Adding USB sockets, extra double sockets, outdoor power, an EV charger supply or smart switches all add cost — but doing it during a rewire is far cheaper than later.
• **Property age and construction.** Older homes with solid walls, lath-and-plaster ceilings or no loft/under-floor access take longer.
• **Regional labour rates.** Rates in and around Doncaster and South Yorkshire are generally more competitive than London and the South East.

How long does a rewire take?

For a typical 3-bed home, allow around 5–10 working days for the electrical work, plus time for plastering and decorating to follow. Smaller properties may take 3–5 days; larger or occupied homes can run to two weeks or more. Your electrician should give you a realistic schedule and explain how power and lighting will be managed if you are living there during the work.

Getting an accurate quote

No reputable electrician can give you a firm rewire price over the phone — the cost lives in the detail of your specific property. A proper quote follows a site visit where we can check the existing cable type, the age of the consumer unit, floor and loft access, and exactly how many circuits and points you want.

At AMP Pro Electrical we are NICEIC- and NAPIT-registered, based in Armthorpe, Doncaster, and we rewire homes across DN postcodes and the wider South Yorkshire area. We will survey your property, talk you through full versus partial options honestly, and give you a clear written quote with no surprises. For a free, no-obligation survey, call us on 0333 577 5464 or [get in touch via our contact page](/contact/) and we will arrange a convenient time to visit.
