Certificate app or business platform. What do you need?
Gas certificate apps are a cheap, tidy way to issue records, but most stop at the paperwork.
A heating business platform like GES runs the whole business from quotes to final payment, and send service reminders that keep your calendar full.
THE REAL QUESTION
It isn’t “which app makes a certificate?”
It’s whether you want a tool that produces digital paperwork, or one that will help you run (and grow) your business alongside the paperwork.
Basic gas certificate apps
A digital cert pad- Issues certificates and emails the PDF
- Records live job-by-job, not as a customer history
- You still quote, invoice and chase somewhere else
- Nothing to bring the next job back through the door
- Priced like a tool because it is one
Great for getting a certificate out of the van and into an inbox.
The platform your business runs on
- Quote → schedule → certificate → invoice → payment, in one place
- Every customer, appliance and job history in one record
- Automated service reminders that fill the diary
- Get paid on site — and see the whole business at a glance
- Built only for UK gas & heating, backed by a 14-year company
The whole job, start to finish — and the repeat work that comes after it.
SIDE BY SIDE
Where a cert app stops, and a platform keeps going
The certificates are the baseline, both do those well. It’s everything around the certificate that decides whether your admin shrinks and your diary grows.

General comparison against the gas certificate app category, not any single product. Individual apps vary.
"Gas Engineer Software is a great fit. For the price range, you'd have to be psychotic to say no — it's such great value for money."

PRICING
Cert apps save you money today, but end up costing you far more
Through 100% automated service reminders and a full job management workflow (quotes, certificates, invoices, full history & more), GES helps you get repeat jobs from the same customers, year on year.
Cert apps are a business expense to save you some time, while GES is an investment to help you run your business and make thousands more.
FULL PLATFORM BENEFITS
What you get when the whole business lives in one place
A diary that fills itself
- Auto service reminders on every certificate
- Next year's service reminder sent automatically
- More repeat business
Why it matters: repeat work is the cheapest work you'll ever win. 1 in 3 reminders becomes a booked job.
One job, start to finish
- Quoting, scheduling, certificates, invoices and payments
- No re-typing across three different apps
- Xero, QuickBooks and Sage integrations
Why it matters: engineers save 6.6+ hours a week and get their evenings back.
A history that becomes an asset
- Every appliance, property and job on the customer
- Full records in seconds
Why it matters: a cert app leaves you with loose PDFs. A platform leaves you with a serviceable customer book worth real money.
Get paid before you leave
- Crezco payment link or QR code on the spot
- Reminders chase late payers for you
Why it matters: Businesses get paid 64% faster with GES.
Built only for the gas trade
- CP12s and full UK compliance built in
- FGA integrations, gas rate calculator, boiler manuals

Why it matters: it's made for how you actually work, not adapted from a generic trades app.
A company that'll still be here
- 14 years of trading
- 7,000+ UK businesses
