How AI agents help heating engineers

Customers get a price and a visit booked while you're on a job.

Without an agent

  • Stopping a service to text back your prices
  • Scrolling your calendar in the van for a free slot
  • Answering new boiler questions from the sofa at 9pm
  • Copying addresses and boiler makes into the jobs sheet

With QX

  • Your £85 service and £75 call out quoted while you work
  • A free slot found and booked in Google Calendar
  • New boiler enquiries answered at 9pm and booked for a survey
  • A jobs sheet row for every visit and new customers in HubSpot

Spend your week on boilers and radiators

QX answers your WhatsApp from Monday to Sunday, so each service and repair gets your full attention.

Straight answers on brands and areas

Customers find out whether you work on Vaillant, Ideal and Worcester Bosch boilers, which HX postcodes you cover and whether you work Saturdays, all from your documents and website.

Services fitted around your repairs

It finds a gap between repairs in your calendar, offers the customer two slots and adds the service with the address and boiler make.

New boilers start with a survey

When someone asks about a new combi, it quotes the starting price from your list and books a free survey, so you measure up before you price the job.

Landlord gas safety checks booked

Landlords get a price for the gas safety record from your list, and the visit goes into your calendar with a note of how the tenant will let you in.

Urgent messages come to you

For a smell of gas, it gives the gas emergency line on 0800 111 999 first. For an elderly customer with no heating, it shares your mobile.

A row for every visit

It adds each job to your jobs sheet with the address, boiler make and price quoted, and saves new customers to your CRM, such as HubSpot.

FAQs

You set the rule. The agent tells the customer to call the gas emergency line on 0800 111 999 straight away, then logs a callback so you can arrange the repair once the supply is made safe.

It quotes the starting price from your price list and books a free survey. The final price comes from you, once you've seen the property.

No. For a fault code, it shares what your fault guide says, then books a visit. The diagnosis stays with you.

No. Each conversation starts with the customer, since it only replies to messages it receives. When a customer asks, it books the service into your calendar.

WhatsApp is included on every plan, and each reply spends credits like any other agent run. The pricing page has the current plans and credit prices.
