Gas engineer software UK: compare prices and features
Start with one question: do you need software to issue gas certificates, manage the work around each visit, or do both? That choice matters more than a long feature list or the lowest advertised price.
Published by WrkGenie, one of the products compared. This is a comparison of supplier documentation and our own product capabilities, rather than a claim that we have tested every product. Official sources are linked below.

For a like-for-like quote, count every person who needs access, identify the plan that contains your required certificates and reminders, then include tax and any add-ons. A certificate-only plan and a full job-management plan serve different needs.
Check certificates and service reminders separately
A diary entry, an appointment reminder and an annual service reminder are separate functions. Ask each supplier to show the exact trigger and message. Also check the certificate types you use, how engineers sign them, how customers receive them and how you retrieve the completed record.
Tradify’s official certificate list includes UK gas records. Commusoft describes its gas certificate and service-contract features. Verify the plan and modules against your own work.
Where WrkGenie fits
WrkGenie is an option for the administration around gas and heating work: customer records, itemised quotes, bookings, invoices and payment tracking. Core includes recurring bookings in the web calendar. Pro adds staff scheduling and customer reminders. Those features do not provide certificate issuance or a dedicated annual certificate-renewal engine.
If you already have a certificate tool, try WrkGenie’s job management for gas engineers alongside it. If your priority is one system for certificates and automated service renewals, compare the specialist options first.
A practical trial checklist for a gas or heating business
- Use one representative job. Add a test customer and the visit location. Keep test details fictional until you are ready to use the system.
- Prepare a quote. Add labour, parts and agreed scope. Check the customer’s view and acceptance process.
- Book the visit. Check how an urgent callout fits around planned work. For a team, test who can see and change the diary.
- Test the paperwork you actually need. In certificate-capable software, produce a sample of each required form. Check service reminders independently from appointment reminders.
- Finish the invoice and handover. Review the invoice, payment status, accounting requirements and access to existing records before switching.

Gas engineer software questions
What is the best software for a sole-trader gas engineer?
Choose around the work you need to manage. If digital gas records and renewal reminders are central, compare certificate-capable products and their relevant plans. If you already have a certificate system and need customers, quotes, bookings and invoices together, trial WrkGenie alongside it.
How much does gas engineer software cost in the UK?
Compare the full monthly cost for the people and features you need. WrkGenie Core is £19.99/month for one user and Pro is £39.99/month for three users. The comparison above shows other suppliers’ published monthly prices or quote-based pricing, checked on 25 October 2026. Annual discounts, VAT and add-ons can change the total.
Does WrkGenie create CP12 gas safety certificates?
No. WrkGenie manages customer records, quotes, bookings and invoices. It does not issue gas safety certificates, validate Gas Safe registration or provide a dedicated certificate-renewal system. Keep those processes in your certificate software or appropriate records.
Are appointment reminders the same as annual service reminders?
No. An appointment reminder concerns a visit that is already booked. A service reminder prompts the next service or renewal to be arranged. Check both workflows separately during a trial, including who receives each reminder and what starts it.
Does Tradify offer gas certificates?
Yes. Tradify’s official UK documentation lists gas forms, including landlord/homeowner gas safety and boiler service records. Its UK pricing page lists compliance certificates on Pro and service reminders on Plus. Check your required forms and plan before subscribing.
