Welsh property check by county

Overview

Built for Wales: county-level values, Land Transaction Tax, and the tighter Welsh rules on holiday lets and planning. Indicative only, no obligation.

Looking at a property in England? Stamp Duty and the value data are different. Use our England check →

What you’ll need: your county, the floor area (m²) and current EPC rating (both free on the EPC register (opens in a new tab)), and an asking or auction price.

Where do I find it?

On the EPC register (opens in a new tab): total floor area near the bottom of the certificate.

The rest of the detail

All optional. The estimate works without them, but each one sharpens it.

Wales works differently, and that’s the point. Purchase tax is Land Transaction Tax (LTT), not SDLT, with its own higher-rate bands. Permitted development and the C5/C6 short-term-let rules differ from England. And holiday lets face the UK’s toughest test: 252 days available and 182 let for business rates, with council-tax premiums up to 300%. We handle all of it in the full appraisal.
County index

Welsh county averages
