House rewire cost in Swansea
What a full rewire really costs in Swansea in 2026 — by bed count, by property age, and what changes the price.
What follows is what we actually do about cost guide in Swansea, rather than a general description of the trade. For Swansea homes — especially coastal terraces in Mumbles and Sketty, older miners' housing in Morriston, and post-war semis around Gorseinon — the answer is shaped by access, plaster condition and whether circuits can be reused. Questions asked during the visit get answered during the visit; there is no benefit to either of us in keeping it mysterious. The paperwork explains it in the same words we would use on site. Most enquiries reaching us from Swansea arrive after something has already been tried. Starting from measurements rather than the previous attempt saves time. Around SA1–SA7 it is coastal salt exposure means outdoor that decides how long the visit takes. Cost guide comes up regularly on Swansea properties, and the honest answer starts with what the installation actually shows.
- In most Swansea cases: includes BS 7671 certification and Part P
- The relevant point here: excludes plastering and decoration
- 3-bed semi: £6,000–£8,000 is one of the few things we would ask you to stop using until tested.
- 4-bed detached is the finding we would check first on a Swansea property.
- A property with includes BS 7671 certification and Part P needs the circuit isolated before further testing.
What's different about Swansea
In most Swansea cases: plastering is the single biggest variable cost after the rewire itself. We coordinate with trusted local plasterers across SA1–SA7 so it doesn't drift.
The relevant point here: coastal salt exposure means outdoor sockets, EV chargers and garden lighting need IP65+ enclosures and stainless fixings to last, which is exactly the situation a full rewire was designed for.
Excludes plastering and decoration. The symptom is the same whichever cause is behind it, so we measure.
