This page breaks down the average windscreen replacement cost in the UK, what affects the price, and when a crack or chip can be legally repaired. We also explain how windscreen claims work with insurance, including excess payments and how it may affect your no-claims bonus.

Below, you’ll find detailed guides comparing mobile services vs dealer glass, typical 2025 costs for full windscreen replacement, and advice on how to handle stone chips, scratches, and stress cracks. We also highlight when repairs are possible — and when full replacement is your only option.
