Winter Peak Coverage
Handle the surge of boiler breakdown calls in November–February without adding staff. CallWrk answers every call, routes emergencies instantly, and books the rest.
Annual Service Campaigns
Automated SMS campaigns remind your customers when their annual boiler service is due — and book the appointment in the same conversation.
Emergency Routing
A 'no heating' call at 2am on Christmas Day gets routed to your on-call engineer immediately. Every other call gets booked for the next available slot.
Gas Safe Enquiry Handling
CallWrk is trained to handle Gas Safe registration enquiries, safety certificate requests, and landlord compliance checks professionally.
"CallWrk answered every call we missed overnight. Our booking rate went from 55% to 90% in the first month. We stopped working weekends and grew revenue by £140K."

HVAC FAQ
Can CallWrk handle Gas Safe-related calls?

How does CallWrk handle boiler emergency calls?
CallWrk identifies urgency signals in real time — 'no heating', 'gas smell', 'carbon monoxide'. Emergency calls are immediately routed to your on-call engineer. Non-urgent calls are booked into the next available slot.
Can it book annual boiler services automatically?
Yes. CallWrk's outbound campaign module sends automated SMS reminders to your customer base when their annual service is due, handles replies, and books the appointment — all without your team getting involved.
