You are deep inside a boiler cabinet, checking a heat exchanger. Your phone rings in your pocket. You cannot answer safely. The caller waits four rings and hangs up. Twenty seconds later they are searching for the next Gas Safe engineer on Google.
This happens to self-employed gas engineers 6 to 8 times every single working day. This guide explains how missed call text back stops that revenue leak, what to say in your SMS, and how to be up and running in under 5 minutes.
Why gas engineers miss more calls than most trades
Gas work demands complete focus. Whether you are servicing a boiler, diagnosing a fault on a heating system, or commissioning a new installation, stopping to take a call is not just inconvenient. In some situations, it is genuinely unsafe. A gas engineer who interrupts a pressure test or a flue integrity check to answer the phone risks missing something critical.
The result: the average UK self-employed gas engineer misses between 6 and 8 calls every working day. Over a year, that is more than 1,500 unanswered leads. Many of those callers are homeowners with a broken boiler, no hot water, or a landlord needing an annual Gas Safe certificate: high-intent, ready-to-book customers.
The 60-second window: Most callers who reach voicemail move on within 60 seconds. They open Google, find the next Gas Safe engineer on the list, and dial them instead. By the time you finish the job and listen to your messages, the opportunity is almost certainly gone.
What is missed call text back?
Missed call text back is an automatic SMS that fires the moment a call goes unanswered. The caller receives a message within seconds, before they have time to call a competitor, telling them you have seen their call and will be in touch shortly.
You do not need to do anything. You finish the job safely. The SMS has already gone. The caller is waiting for your call rather than searching for someone else.
How it works with TextBack Pro: Your TextBack Pro number is linked to your mobile. When a call is missed, our system detects it within seconds and sends your pre-written SMS template to the caller automatically. You see the missed call in your dashboard and call them back when you are free.
Gas safety note: Your SMS template should always include the National Gas Emergency line (0800 111 999) for genuine gas leak emergencies. TextBack Pro lets you include this in your auto-reply so every caller has the right number if they need it urgently.
Why SMS works better than voicemail for gas engineers
Most gas engineers rely on voicemail as their fallback. The data shows it fails almost completely as a lead recovery tool.
| Method | Caller gets response in | % who stay and wait | Leads recovered |
|---|---|---|---|
| Voicemail only | Hours (when you check messages) | ~20% | ~20% |
| Manual callback (same day) | 1 to 4 hours typically | ~30% | ~30% |
| Automatic SMS (within 60s) | Under 60 seconds | ~71% | ~71% |
The difference comes down to timing. An SMS arrives while the caller is still thinking about their problem. Voicemail arrives after they have already booked someone else.
For gas engineers, there is an additional trust dimension. A homeowner with no heating in January is anxious. An immediate professional SMS reply signals that you are reliable and organised, which matters enormously in a trade where customers are letting you into their home and trusting you with their safety.

Here is a realistic estimate based on actual TextBack Pro customer data for self-employed UK gas engineers.
| Metric | Without text back | With TextBack Pro |
|---|---|---|
| Missed calls per day | 7 | 7 |
| Leads that stay engaged | ~20% (1 to 2 per day) | ~71% (5 per day) |
| Jobs booked per month (from missed calls) | ~6 | ~22 |
| Additional revenue per month | n/a | ~�5,440 |
| Cost per month | �0 | From �47 |
These figures assume an average job value of �340 and a 33% conversion rate from engaged lead to booked job, conservative for a gas engineer who responds promptly. Results vary by area, job mix, and callback speed.
Most gas engineers recover the monthly subscription cost in their first 2 days. Booking one additional service or repair per month that would otherwise have been lost to a missed call covers the Starter plan cost more than seven times over.
Is missed call text back GDPR compliant for UK gas engineers?
Yes. Sending a single SMS reply to someone who has just called your business is a service response, not marketing. Under UK GDPR, this falls under legitimate interest: you are responding to a person who initiated contact with you. You do not need prior consent to send that first reply.
You do need consent if you later send follow-up marketing messages such as annual service reminders or promotional offers. TextBack Pro's follow-up sequences include built-in opt-in handling so your marketing stays compliant automatically.
