Builder FAQs
How much does an extension cost?
Single storey extensions typically cost £1,500–£2,500 per square metre in the UK, more in London. Always get a fixed written quote.
Do I need planning permission?
Many extensions fall under permitted development, but loft conversions and larger builds often need planning permission and building regulations approval.
How long does an extension take?
A typical single storey extension takes 3–4 months from groundwork to finish, depending on size and weather.
Should I pay a builder a deposit?
A reasonable deposit for materials is normal, but never pay for the full job upfront. Use a staged payment schedule tied to milestones.
