How Much Does a Full House Rewire Cost in Woking?

A house rewire tends to sit at the back of a homeowner’s mind until circumstances bring it to the front. A surveyor’s report on a recently purchased property flagging the electrical installation as beyond its serviceable life. An EICR returning a string of C1 and C2 codes that cannot be ignored. A persistent fault that keeps tripping the board and resists every attempt at a simple fix. Whatever the trigger, the question that follows is usually the same — what is this going to cost, and how disruptive is it going to be?

Woking has a housing mix that makes this question relevant across a broad spread of property types. The Edwardian and inter-war semis that make up much of the housing stock in Horsell, Maybury and St Johns were built at a time when domestic electrical demand was a fraction of what it is today, and many carry wiring that has been patched and extended rather than properly replaced over the decades. The post-war estates across Sheerwater and Goldsworth Park have installations that in many cases date back to the original build and are now well past the point where they should have been assessed and renewed. Even properties from the 1980s and early 1990s in the newer parts of Woking and the surrounding villages can have installations that are approaching 40 years old.

This post sets out what a full house rewire costs in Woking, what the variables are that affect the final price, and what the process looks like from the first day on site through to a completed, certified installation.

What Does a House Rewire Cost in Woking?

Rewiring costs are driven primarily by property size — the number of rooms, floors and circuits determines the volume of cable, the number of accessories and the number of days the job takes. For Woking and the surrounding Surrey area, current realistic prices from a registered local electrician are:

• One bedroom flat or small terraced house: £3,000–£4,800
• Two bedroom house: £3,800–£6,000
• Three bedroom semi-detached: £5,200–£7,800
• Four bedroom detached: £7,200–£11,000
• Five bedroom or larger: £10,500–£16,000+

These are complete prices — all new cabling, a replacement consumer unit, new sockets, switches and light fittings throughout, full testing and an Electrical Installation Certificate on completion. Replastering and redecoration after the work are separate costs that need to be budgeted alongside the electrical quote.

Woking sits at the higher end of the Surrey market for electrical labour. Its position within the M25 commuter belt — with strong rail links to London Waterloo and a buoyant local economy — means trade rates here are above the national average and above more rural parts of Surrey. They sit below the premium rates of the most expensive commuter villages, but homeowners in GU21 and GU22 postcodes should budget accordingly. The figures above reflect current realistic pricing for this area.

What Affects the Price?

Property Age and Installation History

The age of the wiring and what has been done to it over the years is one of the most significant variables in any rewire cost. Woking’s older housing — the Edwardian terraces and inter-war semis of Horsell, St Johns and the streets around Woking town centre — has frequently seen multiple generations of electrical work layered on top of each other. Original wiring from the 1930s and 1940s was typically rubber-insulated; this becomes brittle and dangerous with age and is a genuine fire risk when it starts to crack or flake. Later additions in PVC cable, consumer unit changes at various points, and modern additions like shower circuits and EV charger points fitted onto ageing infrastructure — the result is often a patchwork installation that takes longer to strip back and replace cleanly than a property with a single consistent installation throughout.

Properties in Sheerwater and Goldsworth Park, built as part of Woking’s post-war expansion, tend to be more consistent in construction but their original installations from the 1950s and 1960s are now 60 to 70 years old. Where these have not been comprehensively updated, they represent exactly the kind of installation that needs replacing rather than repeatedly patched.

Construction Type and How Cables Are Routed

How a property is built directly affects how long a rewire takes. Woking has a cross-section of construction types that each present different challenges.

Older properties with solid brick walls and lath-and-plaster finishes — common in the Edwardian and early inter-war housing across Horsell and Maybury — require cables to be chased into hard plaster surfaces that are more time-consuming to work with than modern plasterboard. Each chase takes longer to cut, and the making good required afterwards is more extensive.

Properties with concrete ground floors — a feature of much of Woking’s post-war housing and some newer construction — cannot have cables run beneath the floor on the ground level. Instead, cables need to travel through the ceiling void from above, be chased into walls, or be run in surface trunking. Each approach has different implications for the decorative finish required afterwards and the time it takes to complete.

The newer homes and apartment developments around Woking town centre and in villages like Pyrford and Byfleet are generally more straightforward in terms of cable routing, with hollow stud walls and accessible floor voids. However, managed blocks and leasehold properties can bring additional constraints around working hours, access and the need to notify other residents or a management company before certain types of work begin.

Circuit Count and Additional Supplies

The number of circuits in a property matters as much as the number of rooms. A standard three-bedroom semi with a ring main, a lighting circuit, a cooker circuit and an immersion heater supply is a defined and manageable scope of work. A property with a separate garage circuit, external lighting, a dedicated EV charger point, a shower circuit, underfloor heating zones and a home office with dedicated data and power is a significantly larger job regardless of how many bedrooms it has.

Be specific about what you want included when requesting quotes, and verify that different quotes are covering the same scope before comparing figures. Two quotes that appear similar on paper can cover materially different scopes of work.

Occupied or Empty

The difference between rewiring an occupied home and an empty one is more significant than most homeowners expect. In a lived-in property, rooms cannot all be taken out of use simultaneously, furniture needs to be moved and protected, and the existing installation needs to be kept partially live at the end of each working day. All of this extends the programme. Electricians price by the day rather than applying an explicit occupied-property surcharge, but the additional time required will be built into the quote.

If you have recently purchased a Woking property and it sits empty before you move in, that window is the optimal time to carry out the rewire. The job runs faster, routing decisions are not constrained by lived-in rooms, and there is no household disruption to manage.

Consumer Unit

A full rewire almost always includes replacing the consumer unit. If the existing board is an old rewireable fuse board, a split-load unit without adequate RCD protection, or simply a unit that has run out of spare ways, replacement is essential. In Woking, a consumer unit replacement as a standalone job typically costs £420–£680 fitted. As part of a full rewire it is generally included in the overall price.

What the Process Involves

A house rewire takes place in two phases with a period of making good in between.

First fix is where all the new cabling is installed — floorboards lifted on timber floors, channels chased into walls, cables pulled through ceiling voids. This is the most disruptive phase of the job. Rooms are inaccessible at various points, dust from chasing is unavoidable, and the property can look considerably worse before it starts to look better. Where possible, the existing installation is kept partially live so the household is not without power at the end of each day.

Once first fix is complete, the making-good phase begins. Plaster channels are filled and brought flush, floorboards are re-secured, and any damaged surfaces are repaired in preparation for decoration. This typically takes one to two weeks including drying time — it is the phase most often overlooked when homeowners are planning the overall programme and budget.

Second fix follows once all surfaces are dry. The consumer unit is installed and connected, all sockets, switches and light fittings are fitted and wired, and the full test sequence is carried out in line with BS 7671. Every circuit is tested for continuity, insulation resistance, polarity and earth loop impedance before the installation is signed off.

An Electrical Installation Certificate is issued on completion. This is a legal requirement under Part P of the Building Regulations and a document you will need when you come to sell the property. Any electrician who completes a rewire without providing one is not operating within the regulatory framework — treat it as a non-negotiable part of the job.

How Long Does a Rewire Take in Woking?

On-site working time by property size:

• One to two bedroom property: two to four days
• Three bedroom semi: four to six days
• Four bedroom detached: seven to ten days
• Larger properties: ten days or more

Total programme from start to certified completion — including making good and drying time between first and second fix — typically runs two to three weeks for a standard Woking semi. Larger or more complex properties take longer.

Part P and Competent Person Schemes

A full house rewire is notifiable work under Part P of the Building Regulations. It must be carried out by an electrician registered with a government-approved competent person scheme — NICEIC, NAPIT and ELECSA are the main ones — who can self-certify the work and notify building control on your behalf. Always verify scheme registration before agreeing to rewiring work. A legitimate registered electrician will confirm their membership without hesitation.

Should You Start With an EICR?

If you are not certain whether the installation needs a full rewire or something less extensive, an EICR is the right starting point. A formal inspection and test grades every defect by severity — from immediate dangers requiring urgent action through to recommendations — and gives you a clear, documented picture of what needs to be done.

EICR costs in Woking typically run between £150 and £300 for a standard domestic property. Many electricians will apply the inspection cost towards the rewire quote if a full replacement turns out to be necessary. For any Woking property where the wiring has not been formally assessed in the last ten years — and particularly for older properties in Horsell, St Johns or Sheerwater — an EICR is a worthwhile investment before committing to a course of action.
