Air Source Heat Pumps

Air Source Heat Pumps (BUS) | GRS Insulation
Survey-Led • Correct Sizing • Comfort & Performance

Air Source Heat Pumps

Heat pump systems are only as good as the design. We take a survey-led approach to sizing, emitter suitability, controls and commissioning — and guide you on the Boiler Upgrade Scheme (BUS) where applicable.

Overview

Designed properly for long-term efficiency

We assess your property and heating system to specify an installation that performs well. If your home needs fabric upgrades first, we’ll tell you — because insulation and heat pumps should work together.

Design priorities

  • Comfort-first design (stable temperatures)
  • Flow temperature and emitter suitability
  • Hot water cylinder and controls strategy
  • Commissioning, testing and handover

Boiler Upgrade Scheme (BUS)

The BUS provides an upfront grant towards replacing fossil fuel heating with a heat pump in England and Wales.

  • £7,500 towards an air source heat pump
  • Typically one grant per property
  • Installer-led: the installer applies for the voucher
  • Hybrid systems (e.g., gas boiler + heat pump) are generally not eligible

We’ll confirm eligibility during the survey stage and explain the process before you proceed.

Note: BUS rules and eligibility are set by Ofgem/Government and can change. We’ll verify the latest position for your property during enquiry/survey stage.
Best results

Fabric first: insulation upgrades

Heat pumps perform best in homes with good insulation and reduced heat loss. If you need improvements, we can deliver insulation upgrades as part of a joined-up plan.
