Boiler breakdown, 06:23
👤 Name: Patricia O'Connor
📞 Phone: 07XXX XXXXXX
📍 Postcode: B15 2TT
🔧 Job: Worcester Bosch Greenstar — no hot water or heating
⚡ Urgency: Emergency — young children in house, no heating
🏠 Property: 1990s detached, owned
💰 Estimated Value: £120-180 callout
📊 Fault: Pressure gauge at 0 — possible leak
Why Heating Engineers Lose Jobs to Missed Calls
Boiler breakdowns are urgent, emotional, and time-sensitive. Customers with no heating in January will call 3-4 engineers. The first to answer — or at least capture the call professionally — gets the job.
Boiler breakdowns peak when you're under a sink or up a loft
January freeze hits. Phones ring constantly. But you're crawling in a loft space, under a kitchen sink, or in a cramped airing cupboard. You physically cannot answer. That 'no heating' call goes to your competitor who books a £180 callout while you're still wrestling with a compression fitting.
Emergency calls need fast triage — voicemail wastes 20 minutes
A voicemail saying 'my boiler's broken' tells you nothing. Is it a £50 pressure top-up or a £4,000 replacement? Katie captures: fault description, boiler make/model, property age, and whether there's hot water. You call back with parts already in the van.
Heating emergencies don't wait for business hours
Boiler breakdowns happen at 6am before work, 10pm when the kids are in bed, and all weekend long. While you're having your Sunday dinner, missed calls stack up. By Monday, those freezing customers have already found another engineer on Checkatrade.
Annual service reminders slip through the cracks
Service customers call to book their annual boiler service. If you miss the call, they often just go to the next engineer on their list. Katie captures every service enquiry with property details, preferred dates, and even sets up recurring annual reminders — building your predictable maintenance pipeline.

Heating Engineer FAQ
Everything you need to know about AI call handling for heating engineering businesses
How much does AI call handling cost for heating engineers?
Whoza.ai starts at £59/month for the Starter plan. One captured boiler breakdown averages £120-£200 callout. A full boiler replacement can be £2,500-£4,500. At £59/month, one emergency callout pays for the whole year. Overage minutes are billed at £0.26/minute.
Can Katie handle emergency boiler breakdown calls at 6am on a Sunday?
Yes. Katie answers 24/7, including weekends, bank holidays, and early mornings. She identifies emergency heating keywords like 'no heating', 'no hot water', 'boiler not working', 'leaking boiler', 'pilot light out', 'pressure dropped' — and marks the enquiry as emergency priority. You get an immediate WhatsApp with 'BOILER EMERGENCY — URGENT' in the header, even at 2am on Christmas morning.
What information does Katie collect from heating customers?
Katie collects: full name, phone number, postcode, property type (house/flat/commercial), boiler make and model (if known), fault description (no heating/no hot water/leaking/strange noise/pressure issue/pilot light), property age, whether it's a rented property, landlord details if applicable, and how they found you.
Can Katie distinguish between a service call and an emergency breakdown?
Yes. Katie is trained to identify urgency from the customer's language. 'Annual service' or 'gas safety certificate' goes to routine scheduling. 'No heating', 'leaking boiler', 'strange smell', or 'pilot light keeps going out' gets emergency priority. She also asks specific diagnostic questions to help you assess urgency before you even call back.
Does Katie handle landlord gas safety certificate enquiries?
Yes. Katie identifies landlord-specific calls by keywords like 'gas safety certificate', 'CP12', 'landlord', 'tenant', or 'rental property'. She captures the number of properties, number of appliances per property, preferred inspection dates, and tenant contact details. Landlord enquiries get flagged as 'landlord/multi-property' in your dashboard for efficient batch scheduling.
How does whoza.ai help with annual service scheduling?
Katie captures service enquiries with full details: boiler make/model (if known), last service date, property address, preferred date range, and whether it's a single boiler or multiple appliances. She can also ask if the customer wants a recurring annual service reminder, building your repeat business pipeline automatically.
Can Katie handle calls about central heating installation quotes?
Yes. Katie captures installation enquiries with: property type and size, number of radiators, current heating system (combi/system/regular/none), fuel type (gas/LPG/oil/electric), property age, budget range, and timeline. These high-value enquiries (£3,000-£8,000+) get flagged as 'installation quote' for priority follow-up.
Will customers trust an AI with their boiler emergency?
Katie introduces herself as your AI assistant and explains that she's capturing details so you can call back prepared. Most customers are relieved to speak to someone immediately rather than leaving a voicemail. In our surveys, 89% of callers are satisfied with the AI experience, and heating customers particularly appreciate that Katie captures fault details that help you diagnose before you arrive.
"I was under a floorboard in Solihull fixing a leak when my phone rang three times. Two were annual service bookings. One was a boiler replacement in Edgbaston worth £3,800. Katie captured all three with full details — boiler models, addresses, tenant contacts. I called back at 5pm and booked the replacement for Thursday. The service calls I scheduled for next month."
