What it is
Travelling to customers' homes to service boilers, fix faults, fit gas appliances and carry out safety checks. You work from a van and take bookings direct from local households.
Your first three steps
- Check the current training and assessment route for gas work (including ACS assessments) with an approved training centre and get costs and dates
- Price up a van, tools, a flue gas analyser and public liability insurance
- Set up a simple website and Google Business Profile, and ask local letting agents about overflow work
Who pays
Homeowners, landlords and letting agents, plus the occasional small commercial customer.
How it makes money
Fixed price for annual servicing and installs, and a call-out fee or hourly rate for repairs. Regular service customers and repeat landlords give steadier work.
Skills that help
- Gas qualifications and hands-on practical skills
- Fault finding and careful safety checks
- Clear communication and tidy paperwork
Watch out for
- You must be on the Gas Safe Register to work legally on gas appliances, check the exact rules for your part of the UK
- Public liability insurance, and check whether you also need cover for work you have done
- Keep your qualifications and tool calibration up to date, and keep proper records for each job
- Training takes time and money before you can earn, so plan for that gap
