TL;DR Gas engineers have something most tradespeople don't: a predictable, recurring revenue stream. Annual boiler services, CP12 checks, and landlord safety records repeat every 12 months without new marketing spend. But only if you've kept track of who the customer is, when they're due, and what was done last time. A CRM for gas engineers makes that possible. This guide covers what it does, why customer records matter so much in gas work, and how Trader CRM helps.
Most tradespeople have to work to fill their diary. A gas engineer with a well-managed customer list doesn't. Every annual boiler service, every landlord CP12 check, every boiler install that needs a follow-up service next year: that's recurring revenue sitting in your customer records, waiting to be activated.
The problem is that most gas engineers manage those records on a spreadsheet, a notebook, or nothing at all. When a reminder doesn't go out, the customer doesn't think to book. They call the next engineer they find online. A job you've already earned quietly goes to someone else.
That's the problem a CRM for tradespeople solves. CRM stands for customer relationship management. For a gas engineer, it's a simple tool that keeps every customer's details, job history, and site notes in one place, accessible from your phone on any callout.
This guide covers what a CRM actually does for a gas engineering business, why the repeat customer opportunity in gas work is unlike most trades, and what to look for if you're a sole trader or running a small team.
What does a CRM actually do for a gas engineer?
A CRM for gas engineers stores every customer's details in one place and lets you track every job from first enquiry through to completion. For a gas engineer, that means boiler details, service history, and site notes on file for every customer, accessible from your phone, on any callout.
In practice, it replaces whatever you're currently using. The notebook with customer addresses, the spreadsheet you update when you get home, the group of contacts in your phone labelled "Dave boiler" that tells you nothing about what was done or when. A CRM puts all of that in one place.
When a customer rings about a boiler you serviced ten months ago, you don't have to guess. You open the app, find the customer, and the service history, appliance notes, and what was flagged last time are right there.
Why is the repeat customer opportunity bigger for gas engineers than most trades?
Gas engineers have a built-in repeat customer base that most tradespeople can only envy. Under the Gas Safety Regulations 1998, every landlord in the UK must have their gas appliances checked annually by a Gas Safe registered engineer. That's a legal obligation, not a preference. It repeats every 12 months, regardless of the economy.
The scale of that opportunity is significant. There are 2.86 million landlords in the UK legally obligated to get a CP12 every 12 months, and around 23 million gas boilers installed in UK homes, most of which need an annual service to maintain the warranty and keep the heating running efficiently. That's a repeat customer base no other trade comes close to.
The catch is that none of it happens automatically. The customer doesn't ring when their service is due. They forget. Or they see a leaflet from another engineer and call them instead. The jobs repeat if you follow up. They don't if you don't.
What happens when gas engineers don't keep proper customer records?
The most common failure mode is simple: the annual service date passes, nobody follows up, and the customer books someone else. It's not dramatic. It just quietly costs you work you'd already earned.
A gas engineer with 300 customers on an annual service schedule has 300 jobs per year that should repeat automatically. Without a proper system, engineers typically remember to follow up with their most regular customers and miss everyone else. Some customers ring to ask. Many don't. A portion of recurring revenue bleeds away every year, without showing up anywhere obvious.
The spreadsheet is usually where this starts to fall apart. Spreadsheets need constant manual updates to stay accurate. For a gas engineer managing service dates across dozens of customers, each with different appliances, different landlord obligations, and different service histories, a spreadsheet stops being manageable quickly. You're not just tracking one date per customer. You're tracking a service history, appliance details, and sometimes multiple properties under one landlord.
That's the point where a proper system pays for itself.
What should a CRM for gas engineers include?
The features that matter for a gas engineering business are practical. A good gas engineer CRM doesn't need to be complex. It needs to cover the basics and work from your phone.
Here's what to look for:
Customer records with appliance notes
Store names, addresses, and numbers in one list. For gas engineers specifically, the notes field is essential. Boiler make, model, and serial number. Whether the customer is a homeowner or a landlord with multiple properties. What was flagged on the last visit. What the customer mentioned for next time. Having that on file means you arrive prepared, not guessing.
Job tracking
Create a job, link it to a customer, and update the status as it moves forward. From enquiry, to booked, to in progress, to complete. Your team can see that status in real time without calling you to ask.
Photo storage
Photos of existing appliances, meter readings, anything that documents the condition of the work on the day. Attached directly to the job, not to a WhatsApp thread or a camera roll with no labels.
Team and subcontractor access
If you work with other engineers or bring in other trades on larger jobs, they need to see the relevant job details without accessing your full customer list. A good CRM lets you control exactly what each person can see. Our guide to managing subcontractors covers how that works in practice.
Mobile access
You're not at a desk. A mobile CRM for tradespeople needs to work properly from a phone on site, not just from a laptop at home.
How does Trader CRM work for a gas engineering business?
Trader CRM is built for tradespeople and small trade teams. Here's what two typical workflows look like.
Homeowner boiler service. A customer rings about their annual boiler service. You create a customer record with their name, address, and number, and add a note with the boiler make and model. You create a job linked to that customer and set the status to enquiry. The customer confirms. You update the status to booked. After the visit, you add notes about what was done, attach any relevant photos, and mark the job complete. When they ring next year, the full service history is right there.
Landlord with two properties. A landlord contacts you about CP12 checks across two rental properties. You create a customer record for the landlord and create a separate job for each property. Both jobs are linked to the same customer record. When you complete the first check, you update that job's status. When you complete the second, you update the other. The landlord's record gives you a clear picture of both properties at a glance. When their renewals come around, you know exactly what's on file.
One price. Full access. No complicated setup. You can see exactly what's included on the Trader CRM features page.
Is Trader CRM right for your gas engineering business?
Trader CRM is built for sole traders and small trade teams who want a simple CRM for gas engineers without learning complicated software. If you're working on your own or with a small team, it's designed for the way you work.
It doesn't currently include gas safety certificates, compliance documentation, or automated service reminders. If those are your main need, you'll want to look at dedicated gas engineer software that handles the compliance side. But if your problem is keeping on top of customers, tracking jobs, and having the right information on file when a customer rings, Trader CRM does that well.
One straightforward monthly price. Full access. No hidden tiers.
Keep track of every customer, every job, every service
The annual service cycle is only reliable income if you've got the records to back it up. A customer you can't find, a service history you can't recall, a landlord whose second property you forgot about: all of that is revenue that should have been yours.
A CRM doesn't chase customers for you. It makes sure that when you do follow up, or when they ring you, everything you need is already there.
If you're a gas engineer looking for a simple way to manage your customers and jobs, try Trader CRM and see what changes.
Frequently Asked Questions
What is the best CRM for gas engineers in the UK?
The best CRM for a UK gas engineer depends on what you need most. For customer records, job tracking, and team access, a simple tool built for tradespeople is usually enough. Trader CRM is built specifically for UK tradespeople and covers those basics well. If you need gas safety certificates, compliance documentation, or automated service reminders built in, you'll want a tool designed specifically for gas work, though those tend to cost significantly more per user.
Can I use a CRM on my phone as a gas engineer?
Yes, and it's important that you can. You're rarely at a desk. Trader CRM is designed to be used on mobile, so you can update job statuses, check customer details, add appliance notes, and share job information with your team from anywhere on site.
Do I need a CRM if I'm a sole trader gas engineer?
If you're managing more than a handful of regular customers, a CRM is worth having even as a sole trader. It means you're not relying on memory or a spreadsheet to track service histories and customer details. It also means that when a landlord rings about a property you serviced 11 months ago, you can pull up the full record in seconds rather than trying to remember what was done.
What's the difference between a CRM and gas engineer software?
A CRM focuses on customer records and job tracking: storing contact details, appliance notes, and job history. Gas engineer software typically goes further, covering certificates, compliance documentation, invoicing, and automated reminders. Trader CRM sits on the CRM side: it handles customers, jobs, and team access, but doesn't currently include certificates or automated reminders. If you need those, dedicated gas engineer platforms are available, though they cost more and take longer to set up.
How long does it take to set up a CRM for my gas engineering business?
With a simple tool like Trader CRM, you can be up and running in under an hour. Add your active customers, create your current jobs, and invite any team members. You don't need to import years of old data on day one. Start with what's on now and build from there.
