If you’re living in an older property, planning a renovation, or just bought a home in Exeter or the surrounding area, you might be wondering:
“How much does a full house rewire actually cost in 2025?”
At EPM, we get this question a lot. And the honest answer is: it depends. But we’re going to break it all down for you — with no fluff, no sales pitch, just the info you need to make a smart, safe decision for your home.
Who Needs a Rewire (And Why It Matters)
Let’s start with the basics. A full rewire is a major electrical job where we replace all the wiring, consumer units, and often sockets, switches, and fittings in your home. It brings everything up to current safety standards and supports modern-day energy demands.
You might need a rewire if:
Your home is over 30 years old and hasn’t been rewired
You’re seeing frequent tripping, flickering lights, or odd smells from sockets
You’re renovating and want to future-proof the wiring
There’s no RCD protection on your fuse board
You’re buying/selling and your EICR flagged issues
Even if the lights still work, old wiring can be dangerous. Faulty electrics are one of the main causes of house fires in the UK. A proper rewire removes that risk.
So, What Does It Cost?
Here’s a ballpark guide for 2025 UK pricing:
Property Type | Average Rewire Cost |
---|---|
1-Bed Flat | £3,000 – £4,000 |
2-Bed Terrace | £4,000 – £5,000 |
3-Bed Semi | £5,000 – £6,500 |
4-Bed Detached | £7,000 – £9,000+ |
Important: These are rough estimates for standard houses with average access and finish levels. Properties with tricky access, listed buildings, or special requests (like data cabling, smart lighting, or surface-mounted fittings) will cost more.
We always give an official estimate after a proper site visit — no guesswork.
What’s Included in a Full Rewire?
A typical full rewire will cover:
New consumer unit with full RCD protection
Complete replacement of old wiring and junction boxes
New sockets, switches and lighting points
Smoke/heat detectors (often required by regs)
Certification and Part P building control notification
Some homeowners choose to add extras like:
USB sockets
External lighting or power
Electric car charger wiring
Smart home controls
We’ll talk through options with you, so you’re only paying for what you actually need.
Can I Stay in the House During a Rewire?
Short answer? It’s possible, but not always comfortable.
Rewiring is messy. Floorboards come up. Walls get chased. Power is often off during the day. If you can stay elsewhere, it usually speeds things up.
If you do stay, we can often do it in phases to minimise disruption. We’ve worked with plenty of Exeter families to make it as painless as possible.
Final Thoughts from EPM
If your electrics are showing their age, don’t wait until there’s a real problem. A rewire is a big job, but it’s an investment in safety, efficiency and future-proofing your home.
At EPM, we give clear, honest advice — and we won’t recommend a rewire unless it’s really needed. If you’re unsure, start with an EICR (Electrical Installation Condition Report). We’ll check everything and explain exactly where you stand.
