No specific qualifications are needed to start. Basic DIY skills, mechanical aptitude, and an understanding of electrical connections are important. Experience in construction, joinery, or engineering is helpful.

Learn about roller doors, sectional doors, up-and-over (canopy and retractable), side-hinged, and industrial doors. Each type has different mechanisms, spring systems, and installation methods.

Frequently Asked Questions
How much do garage door fitters earn?▼
Employed fitters earn £24,000-£35,000. Self-employed fitters earn £30,000-£45,000+. A single installation takes half a day to a full day and earns £200-£500 in labour. Repair call-outs typically earn £80-£150 per visit.
Is garage door fitting dangerous?▼
The main risk is from torsion springs, which are under extreme tension. Improper handling can cause serious injury. Proper training in spring replacement and tensioning is essential. Modern sectional doors have safety features, but respect for the mechanisms is critical.
Do I need electrical qualifications?▼
Basic electrical competence is needed for fitting automated operators. For hardwired electrical connections, Part P compliance may be required. Many fitters work with plug-in operators that don't require electrical qualifications.
What is the most popular type of garage door?▼
Roller doors and sectional doors are now the most popular in the UK, overtaking traditional up-and-over doors. They offer better insulation, security, and don't swing outward, which suits shorter driveways.
Can I fit garage doors as a side business?▼
Yes, some fitters start part-time alongside other work. Weekend installations are popular with homeowners. However, proper training is essential — a badly fitted door is a safety hazard and a reputation killer.
