What it really costs to rewire a house in 2026: honest price ranges by size, what pushes the bill up or down, and what a good rewire quote should include.

In 2026, the cost to rewire a house in the UK typically runs from around £3,000 for a small flat to £8,000 or more for a large four-bed home, with a three-bed house usually landing between £4,000 and £6,000. The exact figure depends on size, access and specification. Here is how it breaks down.

A full rewire is one of the bigger jobs you will have done to a house, so a vague house rewire cost is not much use when you are budgeting.

This guide gives honest 2026 price ranges, explains what moves the number, and sets out what a proper rewire should include, based on the rewires we carry out across South Yorkshire.

How much does it cost to rewire a house in 2026?

As a rough guide, here is what a full rewire tends to cost across the UK in 2026. These are typical market ranges for the electrical work, not fixed FRM prices, and they assume a standard specification:

  • One-bed flat or small property: around £2,300 to £3,500

  • Two-bed house: around £3,000 to £4,500

  • Three-bed house: around £4,000 to £6,000

  • Four-bed house: around £5,500 to £8,000

  • Five-bed or large period property: £8,000 to £12,000 and up

As a very rough cross-check, the electrical work often lands around £100 to £150 per point, meaning each socket, light or switch, which is why the room and socket count drives the price.

These are national figures; homes here in South Yorkshire usually sit at the lower to middle of each range rather than the top, where London and the South East tend to land.

Quotes should also state VAT clearly. Most rewires are charged at the standard rate, though a reduced rate can apply in specific cases, such as a property that has stood empty for two years or more, so it is worth asking. And these figures cover the electrical work and basic making good, not full re-plastering or redecoration, a difference I explain next.

What affects the price of a rewire?

Two identical-looking houses can come back with very different quotes. The main things that move the number are:

  • Size and number of circuits. A bigger house has more sockets, lights and circuits to run and test. It is the single biggest factor.

  • Access and construction. Suspended timber floors and stud walls are easy to run cables through. Solid concrete floors and hard plaster mean more chasing, and more making good afterwards.

  • Specification. Extra sockets, downlights, outside power and smart or network wiring all add up. Good lighting and enough sockets are worth having, but you do not need to gold-plate every room; spend where it earns its keep.

  • Age and layout. Period homes, awkward layouts and previous botched work all add time.

Whether anyone is living in the house matters too, for both cost and disruption, which I come to further down.

What is included in a rewire, and what making good means

A full rewire replaces the installation from the consumer unit out: new cabling throughout, new back boxes, sockets, switches and light fittings, and normally a new consumer unit. It happens in two stages:

  • First fix. Lifting floorboards, chasing channels into walls and running the new cables back to the board. This is the messy, disruptive stage.

  • Second fix. Fitting the sockets, switches, lights and consumer unit, then testing and certifying every circuit to BS 7671.

The finishing is where quotes differ most. Making good means filling the chased walls and holes back to a paintable state.

It does not mean skimming whole walls or redecorating, which are separate trades. If you are happy to fill and paint, taking on that decoration yourself is one honest way to trim the bill.

What a rewire quote often does not cover

Beyond that finishing, a few costs commonly sit outside the electrical price. Budget for them up front so nothing catches you out:

  • Flooring and carpets. Carpets often have to be lifted and may not survive refitting; laminate and tiled floors can complicate access.

  • Kitchens and bathrooms. Rewiring around fitted units and tiling can mean removing and refitting them.

  • Scaffolding or access. Occasionally needed for an external supply or awkward upstairs runs.

  • Asbestos in older homes. In properties decorated before 2000, textured coatings such as old Artex can contain asbestos. If walls or ceilings that need chasing are coated in it, it may need testing and safe handling. A good electrician flags this rather than cutting through it.

How do you know if a house needs rewiring?

A few clear signs that an installation is near the end of its life:

  • Old cabling: rubber, fabric or lead-sheathed cables, or the old red-and-black colours from before 2006.

  • A very old fuse board with rewireable fuses and no RCD protection.

  • Sockets that are scorched, sparse, or still the round-pin type.

  • Frequent faults or tripping.

  • No record of any electrical work for 30 years or more.

If your lights flicker or the board keeps tripping, our guide on why your lights flicker is a good place to start. But age alone is not proof you need a rewire.

The reliable way to know is a condition report: an EICR from a qualified electrician grades the installation and tells you whether you need a full rewire, a partial one, or simply some remedial work, so you are not paying for work you do not need.

Full rewire or partial rewire?

You do not always need a full rewire. A partial rewire replaces part of the installation, for example the socket circuits but not the lighting, or the wiring in an extension tied into a sound existing system.

The same inspection that tells you a rewire is due will tell you whether a partial one will do.

The saving is real, but a partial rewire only makes sense if the rest of the installation is genuinely safe. If the wiring is old throughout, patching half of it is usually a false economy.

How disruptive is a rewire, and when is the best time to do it?

There is no getting around the fact that a rewire is disruptive. Floors come up, walls get chased, dust gets everywhere, and the power goes off in the areas being worked on. It is phased room by room in an occupied home, which is why an empty house is both quicker and cheaper to rewire.

That is worth planning around. If you are buying, getting the rewire done between completion and moving in is far easier than working around your furniture.

And if you are extending or refitting a kitchen anyway, having it done while the walls and floors are already open saves making good twice.

Do you need certificates or permission to rewire a house?

Yes. Rewiring is notifiable work under Part P of the Building Regulations in England and Wales. It must be carried out by a qualified electrician, tested and certified with an Electrical Installation Certificate, and either signed off by a registered competent person or notified to building control.

Keep that certificate safe. You will want it when you sell the house, for an insurer, or for the next EICR. A rewire done without certification is a problem waiting to happen at survey time.

How to compare rewire quotes

Because so much of the price sits in the detail, the only way to compare quotes fairly is to make sure each one is specific. A quote worth trusting will:

  • State how many sockets, lights and circuits are included, so you are comparing like for like.

  • Say clearly whether a new consumer unit is part of the price.

  • Spell out exactly what making good covers.

  • Include testing, certification and building control notification.

  • Be a written, fixed price after a proper look at the property, not a rough figure over the phone.

If one quote comes in far below the rest, something has usually been left out, often the making good or the certification. Cheaper on paper can cost more once the plasterer arrives.

What does a house rewire cost with FRM Electrical?

We quote rewires as a fixed price after visiting the property, so the number you get is the number you pay, barring anything genuinely unforeseen behind the walls, which we would talk through with you first.

You get new wiring throughout, every circuit tested and certified to BS 7671, and the building control paperwork handled for you.

A lot of the homes we rewire around the Dearne Valley are older terraces and former council houses whose wiring has not been touched in decades, so this is familiar ground for us.

We are an NICEIC-approved, family-run team based in Wath upon Dearne. You can read more about our rewires and installation work, check whether we cover your area, or see what to expect from your local electrician in Wath upon Dearne.

If you are weighing up a rewire, the best next step is a free, no-obligation quote. We will take a proper look, tell you honestly what the job actually needs, and put a fixed price in writing.

Frequently asked questions

How long does it take to rewire a house?

Around five to ten working days for a typical three-bed. It is quicker in an empty property and longer for larger or period homes.

Do I have to move out during a rewire?

No, but it is easier if you can. You can stay through it, as long as you do not mind the dust and losing power to one area at a time while it is worked on.

How often does a house need rewiring?

As a rule of thumb, around every 25 to 30 years. But it is the condition of the wiring, not its age, that decides it, which is what an EICR is for.

Will a rewire include a new fuse board?

Almost always. It makes little sense to run brand-new circuits back into an old board, so a full rewire normally includes a new consumer unit.

So, what should you budget for a rewire?

The honest answer on the cost to rewire a house is a range, not a single figure: most two and three-bed homes land between £3,000 and £6,000 for the electrical work, with larger, occupied or higher-spec jobs costing more.
