Do I need planning permission to replace a garage door?

A straight swap — new door, same opening — falls outside planning control for most houses. Where care is needed: listed buildings need consent for most alterations; conservation areas can carry extra restrictions (sometimes through an Article 4 direction); flats and leasehold properties may need the freeholder's agreement; and widening or altering the structural opening is building work, not just a door swap.

If any of those might apply to you, your local planning authority gives a definitive answer, and we flag anything that looks sensitive at survey rather than leaving you to find out later. For everyone else, the practical questions are size, type and budget — the buying guide covers all three.
