Head in the Boiler. Phone Ringing. Missed It. AI Texted Back. Customer Waited.

When a customer calls your gas engineering business and the call goes unanswered — typically because you're mid-install, diagnosing a fault, or elbow-deep in a boiler — the system detects the missed call and sends the caller a professional text from your business number within seconds. The text lets them know you're currently on a job, reassures them that you'll be in touch, and asks them to reply with details about their boiler or heating issue, including make, model, and any error code showing on the display. Most customers reply immediately — especially during winter when they're desperate for their heating to be fixed. You then receive a lead notification containing the caller's phone number, their text reply, and the time of the call. This means your callback isn't a cold return call — it's an informed follow-up where you already know the boiler make, the fault code, and the customer's postcode. For gas engineers, this pre-visit intelligence is incredibly valuable. Knowing that it's a Vaillant F28 before you leave the house means you can bring the right ignition electrode. Knowing it's a Worcester DT1 means you can prepare for a diverter valve issue. The text-back captures leads and accelerates your diagnostic process at the same time.

Winter is when gas engineers face the perfect storm of demand and unavailability. Boiler breakdowns spike as temperatures drop, and your phone rings constantly while you're already attending other breakdowns. During peak season — typically November through February — gas engineers report missing anywhere from six to ten calls per day. Each of those calls represents a homeowner without heating, and every single one of them is going to call another heating engineer within a couple of minutes if nobody answers. The missed call text-back changes the equation entirely. Instead of those callers moving on, they receive an instant text acknowledging their call and asking about their boiler issue. The vast majority of people are willing to wait for a callback when they know you're aware of them — especially if you're the first heating company to make any kind of contact. During winter, this service essentially pays for itself within the first hour of a busy day. A single boiler repair is typically worth £80 to £250. A text-back that rescues even one of those jobs per day across a five-month winter season represents thousands of pounds in revenue that would otherwise have walked to a competitor simply because you were busy doing your job.

Yes, and this is one of the most practically useful features for gas engineers specifically. The text-back message is customised for your business before it goes live, and we always recommend that gas engineers include a line asking for the boiler make, model, and any fault or error code displayed on the screen. Most modern boilers show diagnostic codes — Vaillant uses F codes (F22, F28, F75), Worcester Bosch uses EA, D1, and similar codes, Baxi uses E codes, and Ideal has fault indicators too. When a customer includes this information in their text reply, you essentially get a remote pre-diagnosis before you've even called them back. An F28 on a Vaillant tells you it's likely an ignition failure — you're thinking ignition electrode or gas valve. A D1 on a Worcester suggests a hot water diverter issue. An F1 on a Baxi points toward low water pressure. This intelligence doesn't just save time — it means you can bring the right parts on your first visit, which improves your first-time fix rate, reduces return trips, and gives the customer a faster repair. It's the kind of detail that a standard text-back service wouldn't think to include, but for a Gas Safe registered heating engineer, it makes a genuine operational difference.

This is an important safety point that we take very seriously. The text-back message for gas engineering businesses typically includes a clear note directing anyone who can smell gas to call the National Gas Emergency Service immediately on 0800 111 999 and not to wait for a callback. Gas leaks and carbon monoxide concerns are genuine emergencies that require immediate response from the distribution network emergency engineers, not from a domestic heating engineer who might be an hour away. By including this guidance in the text, you're actually providing a more responsible response than a voicemail ever could. A voicemail message might not mention emergency procedures at all, and the customer would just be sitting there waiting for a callback while potentially in danger. The text-back can include a line like: "If you can smell gas, please call the National Gas Emergency line on 0800 111 999 immediately." For non-emergency heating issues — boiler breakdowns, central heating faults, radiator problems, thermostat issues — the text-back captures the enquiry perfectly. The AI understands the distinction between "my boiler has locked out" and "I can smell gas" and provides appropriate guidance in its response.

The missed call text-back service is £29 per month as an add-on to the Speed Receptionist Core plan, which costs £39 per month. There are no per-text charges and no message limits — you can miss fifty calls in a day during a cold snap and every single caller gets a text without any additional cost. There's a one-time setup fee of £299, which is fully refundable within 30 days. For a gas engineer, the value calculation is simple. Think about what a single boiler breakdown repair is worth to your business: typically between £80 and £250 depending on the fault and parts required. A boiler installation is £1,800 to £3,500. An annual service is £60 to £100, often leading to further repair work. Now consider how many calls you miss in a typical working week. If even one of those missed calls per month would have become a booked job — and statistically, several would — the text-back service pays for itself many times over. There are no contracts, so if you try it and decide it's not for you, you can cancel at any time. Most gas engineers find they can't go back to the old way of losing calls to voicemail once they've seen the text-back in action.

Yes. The text-back works equally well whether you're a sole trader gas engineer, a Gas Safe registered plumbing and heating business, a boiler installation company, a central heating specialist, or a commercial gas firm servicing restaurants and offices. The key principle is the same regardless of business size or specialisation: when you miss a call, the customer gets an instant text instead of silence. For sole traders and one-person heating businesses, the text-back provides a professional first impression that matches what customers expect from larger boiler companies. For businesses with two or three engineers, it catches the overflow calls that even a busy office can't always handle. The wording of the text message is tailored to your specific business, so it reflects the services you actually offer and the tone you want to project. A commercial gas firm serving restaurants and care homes will have a different message tone than a domestic boiler installer working in residential properties. Whatever your corner of the gas and heating industry — whether you focus on Worcester boilers, Vaillant servicing, underfloor heating, warm air systems, or LPG installations — the text-back adapts to your business because it's set up specifically for you, not generated from a template.

The comparison isn't even close. Voicemail was designed for an era when people were willing to leave messages and wait for callbacks — but customer expectations have changed dramatically. When a homeowner's boiler breaks down in January and they call a heating engineer, the last thing they want to do is talk to a machine and hope someone listens to it eventually. Industry research shows that the majority of callers — between 60% and 80% depending on the study — hang up when they reach a voicemail, especially for urgent services like heating and hot water. They simply call the next gas engineer on their list. The text-back reverses this dynamic completely. Instead of asking the customer to do something (leave a voicemail), your business proactively contacts them (via instant text). The psychological difference is enormous. The customer feels looked after rather than ignored. They know you're aware of their call. And the text asks them to reply with their boiler details, which means you receive structured information rather than a garbled voicemail recorded while someone's kids are screaming in the background. The text-back is also cheaper and more reliable than employing a part-time receptionist or paying for a telephone answering service, both of which cost more and still can't guarantee that every single call gets acknowledged within seconds.

Most gas engineering businesses are fully live within 48 hours. The setup process is handled almost entirely by our team and requires very little of your time — roughly fifteen minutes across one or two conversations. During onboarding, we learn about your business: the services you specialise in, your typical customer profile, your working hours, and the tone of voice you want the text to convey. If you primarily do boiler installations and servicing, the text will reflect that. If you're an emergency breakdown specialist, the wording will be different. If you cover both commercial and domestic gas work, we can craft a message that works for both audiences. We draft the text-back message and send it to you for approval — nothing goes live until you're completely happy with the wording. Once approved, we configure the system using your existing business phone number through call forwarding. You don't need a new number, a new SIM, or any app installation. Your customers call the same number they've always used. We conduct full end-to-end testing before going live, including test calls to verify the text arrives correctly and that your lead notifications are working. If you ever need to adjust the message — for example, adding a note about annual service promotions in autumn — you can request a change at any time.

Yes, and this combination is what most gas engineering businesses settle on because it creates the strongest possible lead capture system. The AI phone answering service is the primary layer: when a customer calls and you can't answer, the AI receptionist picks up, has a natural conversation about their boiler or heating issue, asks relevant questions about the make and model, captures their contact details, and sends you a full lead notification. It handles the call as if a trained receptionist with knowledge of heating systems were answering your phone. The missed call text-back is the secondary safety net. If for any reason a call doesn't connect to the AI — perhaps the caller hung up after two rings, or there was a brief network issue — the text-back still catches it. The caller gets an instant text acknowledgement, and you still get their number and potentially their boiler details. Together, the two systems mean that virtually no inbound enquiry goes unacknowledged, whether it's answered by the AI or caught by the text-back. The Core plan at £39 per month includes the AI phone answering, and the text-back is a £29 per month add-on. For a gas engineer losing multiple calls per day during winter, the combined £118 per month is a fraction of the revenue those missed calls represent.

Yes — and the reason is simple: the text arrives at exactly the moment when the customer wants to hear from you. They've just called a gas engineer because they have a heating problem. Nobody answered. They're about to give up and call someone else. Then their phone buzzes with a text that says "sorry we missed your call, we're currently with another customer — could you reply with your boiler details and we'll call you back?" That's not intrusive. That's reassuring. It tells them that your gas engineering business is professional, busy (which implies you're in demand), and responsive — even when you can't answer the phone. The text is written in a human, conversational tone that matches the way a real heating company office would communicate. There are no obvious automated elements, no disclaimer text, and no awkward formatting. Customers consistently believe a real person sent it. More importantly, the text builds trust because it demonstrates competence. The fact that it asks for the boiler make, model, and error code shows the customer that you know what you're doing — you're already thinking about the diagnosis before you've even called them back. That level of professionalism sets the tone for the entire customer relationship once you do connect with them.

Gas engineers frequently work in spaces where mobile signal is poor — basements, utility rooms tucked behind kitchens, and loft spaces with boiler installations. When a call doesn't connect, 85% of callers won't try again. Missed call text-back sends a professional text within seconds of the missed call, acknowledging the customer's attempt and asking about their gas or heating issue. For a customer who smelled gas and called you first because you were recommended, this text could be the difference between winning a loyal customer and losing them to a competitor. At £29 per month, it acts as a last-line safety net that recovers leads even in poor-signal areas. One recovered boiler installation at £2,500-£4,000 justifies the annual cost many times over.

Just drop us a message — routine business updates are free and included in your plan. If you've updated your boiler service pricing, added heat pump servicing, or changed your emergency hours, we'll update your missed call text-back within 24 hours at no extra charge. This covers the kind of day-to-day changes any gas engineer business makes: adjusting prices, tweaking your service list, updating opening hours, or changing your service area. We want your AI to always give your customers accurate, up-to-date information about your gas engineer business.
