Rewire pricing across South Wales has remained broadly stable in 2026 after significant material cost increases in 2022-2023 settled down. Labour costs have increased modestly, offset by efficiencies in cable handling and improved tools. Here is an updated guide to realistic costs across our main service areas.

Why Do Rewire Costs Vary Between Areas?
The largest single variable in rewire pricing across South Wales is property age and wall construction. Cardiff and Penarth have significant stocks of Victorian and Edwardian properties with solid walls. Solid walls require diamond chasing, generate more dust and waste, and take considerably longer to cable than cavity-walled 1930s-1970s properties. A 3-bedroom Victorian terrace in Pontcanna typically takes 2 working days longer than a comparable 1930s semi in Whitchurch, which is reflected in the final price.

Can You Finance a House Rewire?
Financing options vary but several routes exist. Some home improvement lenders offer specific products for major electrical work. Local authorities in Wales occasionally offer grants or low-interest loans for essential safety improvements. A phased rewire is also an option — we prioritise the most dangerous circuits in year one and phase remaining circuits over 2-3 years.
