How to Start a UPVC Window & Door Repair Business in the UK: A Complete Guide
The demand for window and door repairs is rising fast across the UK. With millions of homes fitted with UPVC units, and homeowners seeking cost-effective ways to maintain their properties, there’s never been a better time to start a UPVC window and door repair business.
Whether you’re a tradesperson looking to specialise or someone considering a career shift into a profitable, in-demand service — this guide will show you the essential steps to launch successfully.
What Does a UPVC Repair Business Do?
Unlike full window replacement services, a UPVC repair business focuses on fixing rather than replacing, saving customers time and money. Common repairs include:
Replacing misted or blown double glazing units
Fixing or replacing broken or stiff window and door handles
Adjusting misaligned doors or windows
Repairing or replacing locks, hinges, and seals
Replacing door panels or letterboxes
Draught-proofing and security upgrades
These services are especially attractive to landlords, letting agents, and budget-conscious homeowners.
Do You Need Qualifications or Training?
There are no legal qualifications required to start a UPVC repair business in the UK. However, relevant experience or training is strongly advised to deliver high-quality, safe, and professional results.
Recommended Training Options:
Short trade courses in glazing or fenestration (e.g. GQA Level 2 Certificate in Fenestration Installation)
Manufacturer-specific training on locks, hinges, and hardware systems
On-the-job experience under an experienced fitter
YouTube and online training platforms to supplement practical learning
Additionally, learning basic customer service, quoting, and health and safety practices will set you apart from competitors.
Why the Market Is Growing
The UK has over 27 million households, with the vast majority using UPVC windows and doors — many of which are now 10–30 years old. That’s a massive base of potential clients needing repair rather than full replacement.
Key Drivers of Demand:
Ageing housing stock with degrading seals and glazing
Rising cost of new windows/doors
A push for energy efficiency (repairing leaks = lower bills)
Landlords looking to maintain rental properties affordably
A shift toward sustainability and repair over replace
This means a consistent and recurring demand for UPVC repairs — especially when you market locally and build word-of-mouth referrals.
