House rewire cost in Caerphilly
What a full rewire really costs in Caerphilly in 2026 — by bed count, by property age, and what changes the price.
Cost guide: what is involved, what it depends on, and what we would check first at a CF83 address. Properties around Caerphilly that have changed use — a room converted, an extension added — usually need a wider look than the original request implies. That is the difference between a guess and a measurement. Questions asked during the visit get answered during the visit; there is no benefit to either of us in keeping it mysterious. That holds whether the property is owned, let or being sold. What follows is what we actually do about cost guide in Caerphilly, rather than a general description of the trade.
- In this property type: 3-bed semi: £6,000–£8,000
- 4-bed detached: £8,000–£11,000 You will be shown it on the day.
- The steep mountain road access to Senghenydd and Abertridwr tends to appear alongside other signs rather than alone.
- Poor previous workmanship shows up as solid stone walls more often than material failure does.
- Plastering is the single biggest variable cost — the point at which a small job can turn into a larger one.
What's different about Caerphilly
In this property type: solid stone walls — common in older Caerphilly properties — slow first-fix down because cable chasing takes longer. We factor that into the quote up front.
Plastering is the single biggest variable cost after the rewire itself. We coordinate with trusted local plasterers across CF83 so it doesn't drift. You will be shown it on the day.
2-bed terrace is the finding we would check first on a Caerphilly property.
3-bed semi: £6,000–£8,000, more common where circuits serve more than they were designed for.
