How Much Does a House Rewire Cost in Reading? | Reading Electricians
A house rewire is one of those jobs that most homeowners either do not think about until something goes wrong, or have been quietly putting off because it feels like a large and uncertain expense. The truth is that for many properties in Reading — particularly the Victorian and Edwardian terraces across Caversham, Tilehurst and the Oxford Road corridor, and the post-war housing stock through Whitley, Southcote and Lower Earley — rewiring is not an optional upgrade. It is a safety requirement.
Electrical installations do not last forever. The wiring in a house built before 1970 has almost certainly reached or exceeded its serviceable life, and even properties wired in the 1980s and 1990s may have installations that no longer meet current standards. Knowing what a rewire costs in this part of Berkshire — and what affects the final figure — helps you approach the job with realistic expectations rather than anxiety about an unknown number.
What Does a House Rewire Cost in Reading?
The cost of a full house rewire in Reading depends primarily on the size of the property. As a general guide based on current local rates:
- One bedroom flat or small terraced house: £2,800–£4,500
- Two bedroom house: £3,500–£5,500
- Three bedroom semi-detached: £4,500–£7,000
- Four bedroom detached: £6,500–£10,000
- Five bedroom or larger detached: £9,000–£14,000+
These figures cover the full rewire — new cabling throughout, a new consumer unit, new sockets, switches and light fittings, testing and certification. They do not include redecoration after the work is complete, which is a separate cost to factor in.
Reading sits broadly in line with the South East average for electrical labour rates — higher than the Midlands or North, but below Central London. For properties in the RG1 to RG6 postcodes and the surrounding Berkshire area, the figures above are a realistic starting point.
What Affects the Cost of a House Rewire?
Property Size and Number of Circuits
The single biggest driver of house rewiring costs is how many circuits the property has and how much cable needs to be run. A two-bedroom flat with a small consumer unit and straightforward ring main is a different job to a four-bedroom detached with a separate garage, outbuilding, external lighting and a mix of heating systems. Every additional circuit — cooker circuit, shower circuit, EV charger point, garden supply — adds labour and materials to the job.
Age and Construction of the Property
Reading has a substantial stock of Victorian and Edwardian housing, particularly in the inner suburbs of Caversham Road, Kings Road and the streets surrounding Reading town centre. These properties were built with solid brick walls and lath-and-plaster ceilings, which makes running new cable more labour-intensive than in a more modern property with hollow stud walls and plasterboard.
Properties of this age also tend to have had multiple partial rewires over the decades — a mix of old rubber-insulated wiring, later PVC cabling, and more recent additions sitting alongside each other. Unpicking this and installing a clean, compliant installation takes more time than rewiring a property that has a single consistent installation throughout.
Post-war housing across Whitley Wood, Southcote and parts of Tilehurst tends to be more straightforward in terms of construction, but properties from this era often have wiring that is now 50 or 60 years old and in genuine need of replacement rather than piecemeal repair.
Number of Floors
More floors means more cable runs, more work chasing channels in walls, and more time spent on site. A three-storey Victorian terrace of the kind found in parts of Caversham and the Oxford Road area will cost more to rewire than a bungalow of equivalent floor area, simply because of the additional labour involved in getting cables from one level to another.
Occupied or Empty Property
A rewire in an occupied property — where furniture needs to be moved, rooms remain in use, and disruption needs to be managed around the household — takes longer than rewiring an empty house. Most electricians charge on a day rate rather than adding an explicit occupied-property premium, but the additional time required will be reflected in the overall quote. If you are rewiring a house you have just purchased and it is still empty, that is the best time to do it.
Scope of Work
A full rewire replaces everything — all cabling, all accessories, consumer unit, and earthing arrangements. A partial rewire addresses specific circuits or areas of the property while leaving others in place. Partial rewires are sometimes appropriate, but they are only suitable where the existing installation in the areas being left is in sound condition. An EICR (Electrical Installation Condition Report) carried out before work starts will identify what needs replacing and what can be retained.
If your property only needs a consumer unit upgrade — replacing an old fuse board with a modern unit featuring RCD and RCBO protection — rather than a full rewire, costs are significantly lower. A consumer unit upgrade in Reading typically costs £400–£700 fitted. However, a consumer unit upgrade is not a substitute for a full rewire if the existing cabling is deteriorated or non-compliant. The two are different jobs serving different purposes.
Access and Decorative Finish
Running cable through walls requires either chasing channels in plaster or lifting floorboards to run cable beneath them. Both are disruptive and both will leave the property requiring some degree of redecoration after the work is done. Properties with solid floors — concrete ground floors are common in post-war Reading housing — require cables to be run in surface trunking or through the ceiling void rather than beneath the floor, which affects both the method and the cost.
If you have recently redecorated and want minimal visible disruption, discuss this with your electrician at the quoting stage. It is possible to minimise the surface finish impact, but it may affect the cable routing and add cost.
What Does a House Rewire Involve?
Understanding the process helps set realistic expectations for what living through — or vacating the property during — a rewire actually looks like.
The job typically begins with the electrician carrying out a survey of the existing installation and agreeing the scope of work. For larger properties this may involve a separate visit before the quote is finalised.
First fix involves running all new cabling through the property — under floors, through walls, and across ceilings. This is the most disruptive phase. Floorboards are lifted, channels are cut in walls, and the property will look considerably worse before it looks better. The existing installation is usually left live during this phase where possible so the household is not without power.
Second fix follows once plastering is complete — fitting the consumer unit, sockets, switches, light fittings and any specialist accessories. The installation is then tested thoroughly against the requirements of BS 7671 (the IET Wiring Regulations) before being certified.
An Electrical Installation Certificate is issued on completion. This is a legal document confirming the installation has been designed, constructed and tested to the required standard. It is required by building regulations and will be needed when you come to sell the property. Always make sure your electrician provides this — any contractor who does not issue one at the end of a rewire should be avoided.
How Long Does a House Rewire Take in Reading?
Build time varies by property size, but as a general guide:
- One to two bedroom property: two to four days
- Three bedroom semi: four to six days
- Four bedroom detached: six to ten days
- Larger properties: ten days or more
These are working days on site. If the property needs replastering after first fix — which most rewired properties do to some degree — that adds time for the plaster to dry before second fix can begin. A full rewire from start to certified completion, including replastering and drying time, typically takes two to four weeks end to end for a standard Reading semi.
Do You Need Building Regulations Approval for a House Rewire?
Yes. A full house rewire is notifiable work under Part P of the Building Regulations, meaning it must either be carried out by a registered competent person (a member of a scheme such as NICEIC, NAPIT or ELECSA) or notified to the local authority building control department.
Using a registered electrician is the straightforward route. A competent person scheme member can self-certify the work, issue the necessary certificate, and notify building control on your behalf without you needing to make a separate application. Always check that any electrician you are considering for a rewire is registered with one of the recognised schemes before work begins.
Should You Get an EICR Before Deciding on a Rewire?
An EICR — Electrical Installation Condition Report — is a formal inspection and test of the existing installation. It identifies any defects, deterioration, or non-compliance with current standards and grades them by severity.
For a property where the age and condition of the wiring is unclear — a recently purchased Reading terrace, for example, or a property that has not had any electrical work done in the past 20 years — an EICR is a sensible starting point before committing to a full rewire. It will tell you clearly what condition the installation is in and what work is genuinely needed, rather than leaving you relying on guesswork or a visual inspection alone.
EICR costs in Reading typically run between £150 and £300 for a standard domestic property depending on size. If a full rewire turns out to be needed, many electricians will offset the EICR cost against the rewire quote.
