HVAC answering service for UK heating engineers
Heating fails on the coldest night of the year, and it fails for everyone at once. You are already on a call-out, the phone is ringing, and each caller is trying three engineers because they have no heat and a house full of people. Voco answers every one in your business name, works out whether it is a breakdown or an enquiry, takes the address and the system details, and sends it to your phone before you have finished the job you are on.
29p a minute pay as you go, billed by the second. No contract.
The problem
What do heating engineers lose to missed calls?
Heating engineers lose jobs and enquiries to missed calls, because the caller rings the next business on the list the moment a call goes to voicemail.
- 01
The winter peak arrives all at once
The first hard frost generates a fortnight of breakdown calls while your diary is already full. Those are the calls worth the most, and they go to whoever answers.
- 02
You cannot answer with your hands in a boiler
Most of your working day is spent somewhere you cannot take a call. The customer has no way of knowing whether you are busy or gone, so they ring the next engineer.
- 03
A no-heat call and an installation enquiry sound the same
One is worth a few hundred pounds and one is worth several thousand. Without the detail captured up front you work the callback list in the order it arrived rather than the order that pays.
How Voco helps
How does Voco help heating engineers?
Voco covers the calls you cannot take, and you stay in charge of every customer.
Every breakdown call answered, including at the peak
Voco picks up in your business name whether you are mid job, driving, or it is the third call in ten minutes on the coldest night of the year. Nobody hits an answerphone.
Emergencies escalated, everything else queued
You write the definitions. No heat with a vulnerable occupant, a suspected gas smell, a system leak. Anything matching rings your mobile immediately. Everything else waits until morning, sorted by priority.
System details captured before you get in the van
Make, age, whether it is under warranty, what the symptoms are, whether there is heat, hot water or neither. You arrive knowing what you are looking at, or decide not to go.
Installation enquiries qualified properly
Property type, current system, what prompted the enquiry, whether they have other quotes and their timescale. The calls worth thousands stop being handled like the ones worth hundreds.
What are missed calls costing you?
Cautious by design: we count half your missed calls as real enquiries, assume half of those ring someone else, and that you would win one in four.
Cost
What does an answering service for heating engineers cost?
Voco costs 29p a minute on pay as you go, billed by the second, with no monthly fee and no contract. A two-minute call costs about 58p, so a quiet week costs very little. Busier heating engineers can move to a monthly plan from £49.

HVAC Engineers in detail
The winter peak is when you lose the most work
HVAC demand is not spread evenly and never has been. The first hard frost generates a fortnight of breakdown calls, and it arrives while you are already fully booked. Every one of those callers is ringing three engineers, and the one who answers gets the job.
Around 85% of callers who reach voicemail never call back, and roughly 80% will not leave a message. In a seasonal trade that is worse than it sounds, because the calls you miss in December are not spread across the year. They arrive in the two weeks when your diary is worth the most, and they go to whoever picked up.
What an HVAC answering service actually covers
An HVAC answering service answers calls to your business when you cannot, which for a heating engineer is most of the working day. Hands in a boiler, under a floor, in a loft, or driving between jobs with the radio on.
Voco answers in your business name, in a voice you choose, and works from what you have configured rather than improvising. On a typical call it will:
- Establish whether it is a breakdown, a service, an installation enquiry or a warranty question
- Find out whether there is heat, hot water, both or neither
- Take the caller's name and number, spelled back and confirmed
- Take the address and postcode, and confirm it is inside the area you cover
- Ask what you have told it to ask, such as the make and age of the system, whether it is under warranty, and whether anyone in the property is vulnerable
- Answer the questions you get constantly, such as your hours, your call-out policy and whether you cover a particular manufacturer
- Follow your emergency rules and escalate anything meeting them
- Send you the whole thing by SMS and email within seconds
Where it does not know something, it says so and takes details rather than guessing. It will not quote a price you have not given it, diagnose a fault down the phone, or promise an attendance time you cannot make.
Breakdowns triaged against your own definitions
Not every no-heat call is an emergency, and you are the only person who can decide which ones justify going out at eleven at night.
You write the rules. No heat in December with an elderly occupant, a suspected gas smell, a leak from a system, a total loss of hot water in a family home. Anything matching rings your mobile straight away or goes to whoever is on call. Everything else is captured in full and waiting at seven the next morning, ordered by priority rather than by when it happened to come in.
A gas smell deserves particular thought when you configure this. Voco can be set to tell the caller to turn off the supply, ventilate and ring the National Gas Emergency Service on 0800 111 999 before anything else, rather than treating it as a booking enquiry.
Answering services for HVAC companies with more than one engineer
The setup scales past the sole trader. Where you run several engineers, calls can be routed by job type or by area, service contracts can be separated from one-off breakdowns, and commercial enquiries can follow a different path from domestic ones.
For a larger HVAC company the value shifts from not missing the call to not losing the detail. Every call is logged with a transcript and a recording, so what a customer was told about an attendance window is a matter of record rather than recollection.
Service plans, reminders and the calls they generate
If you run annual service agreements, a meaningful share of your call volume is customers chasing their service, asking what their plan covers, or querying a renewal. None of it is new work and all of it takes time.
Those calls are almost entirely answerable from information you have already written down. Configured properly, Voco handles them in full and escalates only the ones that genuinely need you.
Installation enquiries are worth answering properly
A breakdown is a few hundred pounds. A boiler replacement or a full system installation is several thousand, and the enquiry arrives looking exactly like every other call.
Voco can capture what you need to decide whether it is worth a site visit: property type, current system and its age, what has prompted the enquiry, whether they have had other quotes and their timescale. You ring back able to price the visit rather than starting from a name and a number.
AI call handling for heating engineers, in practice
Nothing to install and no new number. Calls forward from the number already on your van and your website, and you choose when: only when you do not pick up, only outside your hours, or every call.
Voco books into a connected calendar where you have enabled that. Otherwise the job arrives with everything already captured, ready to put into whatever you use. If you run a specific field service platform and want jobs to land inside it, tell us which one. Integration priorities are set by what customers ask for rather than by a list on a website.
Getting started before the cold snap
You can be live in minutes. Signing up walks you through a short setup flow covering your business details, the systems and manufacturers you work with, your hours, your area and the questions you get asked most. Choose a voice, confirm, and it is ready to answer.
Getting the triage right takes around an hour and is the part worth doing carefully, particularly your gas safety wording and your definition of an out-of-hours emergency. Test it on your own phone before you forward anything. Worth doing in September rather than the week the temperature drops.
There is no setup fee, no contract, and a 30 day money-back guarantee. Voco costs 29p a minute with no monthly fee, or a monthly plan if your call volume is steady.
