Software for gas engineers
Business software that keeps your gas business compliant and organised.
Fusion Flow gives Gas Safe engineers and heating businesses a Zoho-powered system for managing boiler service reminders, CP12 renewals, job records and customer history — reducing admin and capturing recurring revenue.
Why gas engineers choose Fusion Flow
The market
Gas work runs on renewal dates somebody has to own.
Almost every gas customer is a repeat customer with a fixed anniversary — a landlord certificate, a manufacturer warranty service, a service plan visit. The business either owns those dates or loses them to whoever writes first.
The landlord certificate is a legal deadline, not a preference
A rented property needs its gas safety check every twelve months, and the landlord or agent has to hold the record. That makes the renewal a booking they must make. Whoever reminds them first, with the property already on file, usually keeps it.
Autumn decides the year
Services cluster before the heating goes on and breakdowns cluster after it. If the service book is not filled in September you spend the winter on emergency call-outs at whatever hours you can find, and the planned work never catches up.
Boiler replacements come from services you already do
The engineer standing in front of a twelve-year-old boiler knows it is close. That conversation, followed up properly a few weeks later with a written option, is where installation revenue actually comes from — not from cold enquiries off the internet.
The problem
What's holding most
gas engineers back.
Annual service reminders are done manually or not at all
Every boiler customer is a recurring revenue opportunity. Without automated reminders, these opportunities go to whoever the customer happens to call next year.
CP12 and gas safety certificate records scattered
Landlord gas safety certificates have strict renewal requirements. Losing track of renewal dates creates compliance risk and lost recurring work.
Seasonal demand peaks without advance booking
Autumn and winter are the busiest periods. Businesses that automate service reminders in August fill their diary before competitors who don't.
Quotes from last year that were never followed up
Old quotes for boiler replacements and upgrades represent warm leads. A CRM keeps these visible and followable.

FAQs
Questions about Fusion Flow
for gas engineers.
Can Fusion Flow send boiler service reminders automatically?
Yes — this is one of the highest-value features for gas engineers. We configure automated annual reminder sequences based on each customer's last service date.
Can it track CP12 renewal dates for landlords?
Yes. We set up certificate tracking with renewal dates per property and automated reminder sequences so landlords receive advance notice.
How does it handle multiple properties for the same landlord?
Each property is linked to the landlord's CRM record with its own certificate dates and service history, so renewals are tracked property by property.
Can it manage both domestic and commercial gas work?
Yes. Different job types, certificate types and reminder sequences can be configured for domestic, landlord and commercial gas work.
How long does setup take?
Most gas engineering businesses are live within 1–2 weeks, including the reminder setup and data migration.
Can it track CP12 expiry across a whole letting agent's portfolio?
Yes. Each property sits under the agent or landlord account with its own certificate date, so you can see the whole portfolio, batch the renewals due in a given month and route an engineer around them efficiently.
Can it flag boilers approaching end of life for replacement quotes?
Yes. Appliance age, make and model are recorded at each service visit, so you can pull the customers with ageing boilers and offer a replacement quote before it fails in January rather than after.
How much does Zoho One cost?
Zoho One bundles the full suite of 45+ integrated business apps for roughly £37–£45 per user per month, depending on your plan and headcount. That includes a professional mailbox on your own domain, so most businesses can drop their Google Workspace or Microsoft 365 licences altogether. We break the numbers down in our guide to Zoho One pricing in the UK, or talk to our Zoho team about the right plan.
