What to look for
What heating software should do
Shown in JobSheet with a sample heating firm. The full walk-through is on the JobSheet for heating engineers page.
01 Schedule
Services and breakdowns on one diary
Annual services, powerflushes and breakdown visits share one week, each assigned to a named engineer.
02 Quote
Quote the work, photograph the data plate
Itemised quotes for services, filters and flushes, with boiler notes and photos kept on the job.
03 Invoice
Mark it done, then invoice it
The engineer records the work carried out, and the office raises the invoice from the same job.
Separate software from compliance
Job management software should help you:
- Book service visits and breakdowns
- Store notes, photos, and parts against the job
- Track quotes and invoices
It does not replace Gas Safe registration, manufacturer training, or your own certificate workflow unless the vendor clearly ships those features. JobSheet does not provide gas certificates in the current release.
Features heating teams use daily
- Annual service diaries and reminder notes on the schedule
- Boiler model and location notes on the job sheet
- Ltd housing providers imported via Companies House
- Engineer logins so each tech sees their run

Questions
Common questions
What is the best software for heating engineers in the UK?
It depends on size. Larger gas firms with service contracts often compare Commusoft and BigChange. Smaller teams that mainly need a diary, job sheets and invoicing may prefer a simpler tool with a published price, such as JobSheet.
Does JobSheet produce Gas Safe certificates?
No. JobSheet does not provide gas certificates in the current release, and software does not replace Gas Safe registration or manufacturer training. Keep your certificate workflow, and use JobSheet for the diary, job sheets, quotes and invoices.
Can I schedule annual boiler services?
Yes. Book services on the shared diary, add reminder notes, and use recurring job sheets for regular visits. Full service-contract management is a strength of tools such as Commusoft.
Can I invoice landlords and housing providers by their registered name?
Yes. JobSheet can import a limited company's registered name and office address from Companies House. See invoicing Ltd customers with the right Companies House name.
How much does heating engineer software cost?
JobSheet is £15/month plus £5 per extra user. Commusoft and BigChange do not publish prices, so ask each for a written quote. Confirm current prices on each vendor's site.
