Frequently Asked Questions — Extension Builders in Edinburgh
Do I need a building warrant for an extension in Edinburgh?
Yes — almost all extensions in Scotland require a building warrant from your local council. This is separate from planning permission. Your builder should handle the building warrant application, working with a structural engineer for drawings and calculations.
How much does a house extension cost in Edinburgh?
A single-storey rear extension typically costs £1,200–£1,800 per square metre; two-storey £1,000–£1,500 per sqm. A typical 4m × 5m single-storey extension might cost £25,000–£45,000 all-in. Always get at least 3 detailed quotes.
Do Edinburgh extension builders cover surrounding areas?
Yes — most extension builders based in Edinburgh cover the wider district including Livingston, Bathgate, Linlithgow, Penicuik and surrounding areas. Some also cover the wider Central Belt.
What qualifications should an extension builder in Edinburgh have?
Your builder should carry public liability insurance (at least £2 million), employer's liability if they have staff, and provide references. FMB or NHBC membership is a good sign. They should manage building warrants, structural engineers, and building control inspections.
