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.

Do you need planning permission for a house renovation in Llanelli?
Before anything is built in Llanelli, we confirm which approvals apply in Wales. In Wales internal renovation usually does not need planning permission unless the house is listed. Notifiable work must meet building regulations.
Building regulations in Wales are set by the Welsh Government. Approval comes from the council’s building control service or a registered building control approver, with inspections during the work and a completion certificate at the end.
At the survey we check your house’s planning history and any restrictions, and tell you which route applies.
