How regional refurbishment costs work
- 1Start from national benchmarks

- 2Apply the regional factor
Wales sits at ×0.95 versus the national baseline — mostly driven by local labour rates.
- 3Adjust for your property
Condition, spec and access move the number further. Always confirm with local contractor quotes before committing.
Wales runs below the UK baseline on cost, with affordable stock in the valleys and strong demand in Cardiff and Swansea. Note that some regulations (including licensing and energy rules) differ from England — always check Welsh Government guidance.
Major areas in Wales include Cardiff, Swansea, Newport, Wrexham and Bangor. Costs vary within the region too — city-centre access and rural travel both add to trade time — so treat these as a regional starting point, not a substitute for local quotes.
