Calls you miss on the tools

Landlord gas safety checks, boiler swaps and breakdowns all arrive by phone, often while you're working. Every unanswered call is a customer who may try someone else.

Example calls, and how InstallerLine handles them

A landlord needs gas safety certificates

The call: A landlord rings needing gas safety checks on three rental flats before the current certificates run out.

What InstallerLine does: Takes the landlord's details and all three addresses and postcodes, asks about access and tenants' contact details, and pencils in a provisional slot for the first visit.

What you get: A text and email with the addresses, the dates the certificates run out (if the caller knows them) and the provisional slot to confirm.

A caller says they can smell gas

The call: A homeowner rings saying there's a strong smell of gas in the kitchen.

What InstallerLine does: Stops and gives the safety instructions: leave the property, don't use switches or flames, and call the National Gas Emergency Service on 0800 111 999 (999 if anyone's in danger). It doesn't pencil anything in.

What you get: An immediate safety alert with the caller's details, so you can follow up once the emergency service has made it safe.

A boiler replacement quote

The call: Someone's old boiler keeps failing and they want a price for a new one.

What InstallerLine does: Takes the property details and current boiler type, never quotes a price you haven't approved, and pencils in a survey visit as provisional.

What you get: A summary and a provisional survey slot to confirm with one tap.

What it handles for Gas Safe registered engineers

✅ It will

  • Answer in your business name, 24/7, in plain British English
  • Tell callers it's an AI assistant and that the call is recorded
  • Take name, phone, postcode, address and job details, and read them back
  • Landlord gas safety certificates, including several properties at once
  • Boiler servicing, replacement surveys and cooker or fire installs
  • Gas smell and carbon monoxide calls, with clear safety instructions
  • Approved FAQs: Gas Safe registration, area, hours
  • Text back callers who hang up

❌ It won't

  • Pretend to be a person
  • Diagnose faults or give technical advice
  • Quote prices you haven't approved
  • Promise a firm time or price, or take card payments
  • Treat emergencies as routine jobs
Gas and carbon monoxide safety comes first. If a caller mentions a gas smell, the AI tells them to leave the property, avoid switches and flames, and call the National Gas Emergency Service free on 0800 111 999 (or 999 if anyone is in danger). For a carbon monoxide alarm or symptoms, it tells them to stop using the appliance, get into fresh air, call 0800 111 999 and get medical help. It never pencils these in as normal jobs, and you get an immediate safety alert.

Standard UK call rates apply. Calls to the demo line are recorded and transcribed so we can improve the service. Borders Heating isn't a real firm, so nobody will be sent out.

Questions from Gas Safe registered engineers

Does InstallerLine work for Gas Safe registered engineers?

Yes. We set it up for your firm: your services, area, hours, the questions you want asked and what counts as urgent. You approve exactly what it's allowed to say before it goes live.

Do I need to change my phone number?

No. You keep your number and divert calls you don't answer (or all calls, if you prefer) to your InstallerLine number. Your phone provider may charge for diverted calls, depending on your plan.

Does it confirm jobs on its own?

No. On Receptionist and Busy Firm it pencils jobs and visits into your diary as provisional, and nothing is final until you confirm with one tap or reply with another time. If you don't confirm within 24 hours (or 2 hours before the slot, if sooner), the slot is released and the caller is told you'll ring them.

Will callers know it's an AI?

Yes. It says so at the start of every call, and it tells callers the call is recorded.

Does it follow gas safety rules?

It gives the standard National Gas Emergency Service instructions and number (0800 111 999) whenever a caller mentions a gas smell or CO, and it never pencils those calls in as normal jobs. You get an immediate safety alert.

Can it tell callers I'm Gas Safe registered?

Yes, if you approve that wording. We set up your FAQs with you, and the AI only says what you've signed off.
