Boiler replacement — Heating installer — Professionals

Boiler-replacement leads need clear appliance identification and system assessment. Providers should establish the fuel or power technology, review current demand and interfaces and avoid promising a simple swap when the installation or hot-water arrangement requires wider changes.

Service scope

Assessment and replacement of an existing boiler with a specified suitable appliance, coordinating fuel or electrical supply, water connections, controls and any combustion-related interfaces where applicable. Boilers are not all gas-fired, and replacement does not automatically mean that every existing connection or emitter remains suitable.

What is normally included

  • Existing appliance and system assessment
  • Defined replacement and connection scope
  • Commissioning and required handover records

What is not included

  • Automatic like-for-like suitability
  • A gas-only interpretation of every boiler enquiry

Qualification checks

  • Identify fuel and appliance
  • Review system configuration
  • Confirm replacement suitability
  • Check relevant specialist qualifications
  • Allocate controls and connection work

Quote guidance

Itemise the boiler, removal, installation materials, controls and commissioning. Identify technology-dependent flue, electrical or other connection work explicitly, and state any assumptions about retained emitters or pipe condition.

Lead risks

  • A failed boiler may be blamed for a wider system fault
  • A quoted appliance model may not match the customer's hot-water needs
