In short
Nexley is the AI back office for UK gas and heating engineers. It sends your annual service and CP12 reminders, books the replies into your diary, identifies parts from a photo of the data plate and prices them at your merchants, and invoices the day the job's done.
Invoices to landlords and agents are chased on your schedule. Nothing goes out until you approve it in WhatsApp. £799 a month for the firm, with 7 days free.
Every boiler you fit is a service due next year. Nexley sends the reminders, books the visits and keeps the CP12s in date.
Five breakdowns. The reminders went out at seven.

In detail
Gas and heating, in detail.
A heating firm's week is a moving puzzle: emergency call-outs landing on top of booked services, landlord certificates expiring in awkward clusters, and quotes for boiler swaps that go cold because they took four days to send. Most plumbing and heating software only tracks that puzzle. Nexley runs it: matching jobs to the right Gas Safe engineer, keeping the certificate calendar ahead of the expiry dates, and turning site visits into priced quotes the same afternoon.
- Jobs matched to qualification and postcode
- CP12 renewals chased before they lapse
- Boiler quotes out while the lead is warm
Scheduling is a skills problem wearing a diary costume
Any calendar can put a name against a time slot. The heating version of the problem is harder: the job needs someone whose tickets cover it — domestic gas, unvented hot water, oil, LPG — who is also somewhere near the postcode, with the van stock to finish rather than survey. Nexley holds who is qualified for what and schedules against both constraints at once, which is the difference between a day of completed jobs and a day of engineers meeting each other coming the other way on the ring road. When an emergency bumps the plan, the reshuffle respects the same rules — and the customers being moved hear about it from you, not from an empty doorstep. For the call-outs that start with a code on the display, our guide to reading boiler fault codes explains why one code can mean different things on different makes, and which checks need a Gas Safe engineer.
The certificate calendar that never lapses
Landlord work is won on reliability and lost on a single missed renewal. Every CP12 Nexley files carries its expiry date; weeks ahead it proposes the booking, drafts the messages to landlord and tenant for access, and chases the reply — you approve, it arranges. After the visit the record is issued and filed against the property, engineer registration number and all, so when a letting agent asks for three years of certificates on a portfolio the answer takes a minute. Firms grow on this: agents hand portfolios to the contractor whose paperwork never needs chasing, and the client portal lets them see their compliance position without ringing you. What the record itself must show, and how often a landlord needs one, is set out in our CP12 gas safety record guide.
Quoted today beats cheaper next week
A boiler replacement enquiry is perishable — the household is cold and ringing three firms. Speed wins work that price alone does not: describe the installation from the survey and automated quoting drafts the options from your rates — the straight swap, the swap with a powerflush where the system water tells you it needs one, the filter and controls upsell — as a clean priced document you approve from the van. Service contracts get the same treatment at yearly scale: priced from real cost per visit, invoiced on schedule, renewed without a spreadsheet ritual every January. The office work that used to wait for Sunday evening — job sheets, invoices, chasing — is the back office layer working through the same approval rule: nothing reaches a customer without your say-so.
