Service reminders: the repeat income
Annual boiler services and landlord gas safety checks are the work that comes back every year if you remind people. Landlords must have gas appliances they provide checked every 12 months by a Gas Safe registered engineer, keep the record for 2 years, and give existing tenants a copy within 28 days (HSE, checked 17 October 2026). Under the 2018 amendment, the check can be done up to 2 months early while keeping the original deadline date, so a reminder at 10 months gives landlords time to book.
Commusoft is built for heating and service firms, with service reminders, stock and a customer portal, priced on quote. Powered Now is a UK app with compliance certificates and reminders at a flat price for one person. Compare: Powered Now vs Commusoft, Tradify vs Commusoft, ServiceM8 vs Commusoft. AI writes the reminder text. Marketing messages to people who aren't existing customers need consent.
Heat pump quotes and the Boiler Upgrade Scheme
Heat pump customers have lots of questions, and AI is good at a plain-English explainer to send with the quote. Get the grant facts right yourself. In England and Wales, the Boiler Upgrade Scheme gives £7,500 towards an air source or ground source heat pump, £5,000 towards a biomass boiler and £2,500 towards an air-to-air heat pump; until March 2027 there's an extra £1,500 for air or ground source heat pumps where the property is heated by oil or LPG and has no mains gas connection. There's no grant for hybrid systems (GOV.UK, checked 17 October 2026).
The customer gets quotes from MCS certified installers, and the installer applies on their behalf through Ofgem; the grant comes off the price on the quote and invoice, and the heat pump must be commissioned within 120 days of applying (GOV.UK). Set your quote out with the grant shown as a deduction using the AI quote generator or your job app. Prompts for boiler, heat pump and gas safety conversations: ChatGPT prompts for plumbers.
Breakdown calls in winter
When the first cold snap hits, the phone rings all day. An AI receptionist can take the boiler make, any fault code, the address and whether there are vulnerable people in the home, then text you a list to triage. Set it to give 0800 111 999 to anyone who smells gas (HSE) and never to talk a caller through a repair. Set-up: AI receptionist for heating engineers. Costs: AI receptionist cost UK. For your voicemail, the voicemail greeting generator adds the gas emergency line automatically.
Invoicing and accounts
Heating firms with engineers and vans usually outgrow free apps quickly. Xero or QuickBooks link to most job apps; FreeAgent suits sole traders. Making Tax Digital for Income Tax has applied since 6 April 2026 to sole traders with qualifying income over £50,000 (guide). Chase late payers, including letting agents, with the payment reminder generator. See invoicing apps for tradesmen, invoicing for heating engineers and bookkeeping for heating engineers.
Reviews and social posts
Ask for a Google review after installs and services, reply with the review reply generator, and post finished installs with the social post generator (no house numbers). Guides: reviews for heating engineers, social for heating engineers.

What AI must not do for heating engineers
Gas work in homes must be done by a Gas Safe registered engineer competent in that area of work (HSE). Don't use AI for flue, ventilation, sizing or heat loss decisions, and don't let it give customers safety advice beyond turning appliances off, opening windows and calling 0800 111 999 for a suspected leak. For heat pumps, follow the MCS standards and manufacturer instructions.
