What is a house renovation?
A house renovation brings an older or tired home up to date. It can include rewiring, a new heating system, replastering, new floors, windows, kitchens and bathrooms, and changes to the layout. A full renovation is often combined with an extension or loft conversion.
How much does a house renovation cost in West Glamorgan?
In West Glamorgan, a house renovation typically costs £850–£1,650 per m² for a medium to full renovation, including VAT at 20% (5% may apply to homes empty for two years or more).
