Head to head
Checking sources…Gas Engineer Software is uk gas safe registered engineers, heating engineers, and plumbing businesses from sole traders to teams of 6+; not suitable for electrical-only or multi-trade contractors. Here is where it beats us, where we beat it, and what each one actually costs.
Gas Engineer Software is the most focused product in this group — if you are a heating or plumbing business, it offers genuinely trade-native features (CP12 certificates, oil records, gas rate calculator, 2,300+ boiler manuals with AI assist, analyser integration) at a lower price point than generic FSM software, backed by UK support that understands the trade.
Narrow vertical scope means it is not a viable choice for electricians, builders, or multi-trade businesses; the integrations page returned 404, suggesting the integration documentation is thin; no GoCardless, CIS, or BNPL payment options were found.
The calendar and planning features feel clunky compared to more modern alternatives, with limited customisation making it feel basic beyond certificate generation.

FAQ
Every competitor cell is read from that company's own public pages and dated. Where a vendor doesn't publish an answer we mark it not published rather than assuming a no — an absence of evidence isn't evidence of absence. Prices are shown in the currency the vendor actually bills in; we don't convert silently. Checking sources….
We compete with these companies, so treat this as our reading of the public facts, not a neutral audit. If something here is wrong or out of date — especially if it's your product — tell us and we'll correct it.
