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 Maesteg?
In Maesteg, 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). For a typical 90 m² project that is roughly £76,500–£148,500. We start from a UK-wide guide and adjust it for Wales, where labour and materials are typically about 8% below average.
