If your home is older, has outdated wiring or you are planning major renovation work, a full or partial rewire might be on your mind. It is one of those jobs that homeowners put off for as long as possible, but a safe and modern electrical system makes a huge difference to your everyday living, your energy efficiency and your peace of mind.
At JPR Electrical, we often get asked the same question. How much does it actually cost to rewire a house? The answer is that it depends on several factors, but we will break it all down for you here so you know exactly what to expect.
What Affects the Cost of a House Rewire?
Every property is different, and there is no single fixed price. The overall cost depends on a few key points.
1. The Size of the Property
Unsurprisingly, larger homes require more materials and more labour time. A small one-bedroom flat will cost far less to rewire than a large five-bedroom detached house.
2. The Condition of the Existing Wiring
Older homes, especially those with wiring from the 1960s or earlier, often need more extensive work. Sometimes, additional safety upgrades or consumer unit replacements are needed too.
3. Whether the Property Is Occupied
If the house is empty, the work is faster, cleaner and more cost-effective. If you are living in the home during the rewire, the job needs to be phased around you, which can add time.
4. The Specification You Choose
Spotlights, extra sockets, smart lighting, outdoor electrics and upgraded fittings can all influence the final cost.
5. Ease of Access
Plasterboard walls and accessible loft spaces help reduce labour time. Solid walls or limited access areas may take a bit longer.
Typical House Rewire Costs in the UK
To give you a rough guide, here is what homeowners can usually expect. These figures include materials, labour and testing.
- 1 – 2 bedroom flat: £3,000 to £4,500
- 2 – 3 bedroom house: £4,500 to £6,500
- 3 – 4 bedroom house: £6,500 to £8,500
- Large 4 – 5 bedroom property: £8,500 to £12,000+
These are average price ranges, and the exact cost will depend on your layout, your requirements and the condition of your current electrical system.
How Long Does a Rewire Take?
Most full rewires take:
- 2 – 4 days for a flat
- 4 – 7 days for an average house
- Up to 10 days for large or complex properties
If you are renovating, the best time to rewire is before plastering, decorating or installing a new kitchen. It keeps disruption to a minimum and helps keep costs down.
Do You Need a Full Rewire or Just an Upgrade?
Not every home needs a complete rewire. Sometimes a consumer unit upgrade, extra sockets or partial rewiring in key rooms is enough.
You may need a full rewire if you notice:
- Regular tripping or blown fuses
- Old-style fuse boxes
- Fabric or rubber-coated cables
- Scorch marks or burning smells
- Flickering lights or unreliable sockets
- No earthing on metal switches or fittings
If you are unsure, an Electrical Installation Condition Report (EICR) will tell you exactly what condition your wiring is in and whether any work is required.
Is It Worth the Investment?
Absolutely. Rewiring is one of the most valuable improvements you can make to your home. It ensures a safe and compliant electrical system, etter reliability day to day, the ability to run modern appliances, improved energy efficiency, and increased property value. It may not be as exciting as a new kitchen, but it is far more important in the long run.
