Heat pump servicing and aftercare business is a UK business you could start with £5-15k in capital, with a realistic year-one revenue of £20-50k and first revenue in 1-3 months. It scores 9/10 Opportunity and 6/10 Validation Depth on the startup.compare framework.
The UK installed base of heat pumps keeps growing, but the people who can lawfully service them are scarce: roughly 1,500 MCS-certified heat pump installers against about 135,000 gas engineers. Annual servicing is mandatory to keep most manufacturer warranties valid, yet dedicated servicing-and-aftercare specialists are thin on the ground. The gap is a recurring-revenue maintenance tail on an expanding installed base, served by too few credentialed engineers.
The Clean Heat Market Mechanism came into force on 1 April 2025 and its heat pump target rose to 8% of relevant boiler sales on 1 April 2026, with Boiler Upgrade Scheme grants driving installs. The cumulative certified base has passed 250,000 units, each needing a paid annual service for 10 to 15 years to keep warranty and grant documentation valid.
Regulatory position: High: F-Gas certification legally required for refrigerant-circuit work; MCS or manufacturer approval to validate warranty work.

Confirm the closest-SIC five-year survival rate (SIC 43.22, plumbing and heat/air-conditioning installation) from ONS Business Demography tables rather than the national figure. Verify how many homeowners actually pay for a standalone annual service rather than letting warranties lapse; demand is partly inferred from warranty terms, not yet observed paid behaviour at scale. Confirm manufacturer rules on who may carry out warranty-validating service in your area, and the realistic services per day a solo engineer achieves including travel. Binding leg: Demand-evidence.
