Non-Condensing Boiler Replacement

If your home still runs a non-condensing boiler, you are likely paying more than you need for heating and hot water. These older boilers are far less efficient than modern condensing models and are common in UK homes built before 2005. We replace non-condensing gas, oil, and LPG boilers with high-efficiency systems, and where eligible we help you access the Government Boiler Upgrade Scheme to move to a low-carbon air source heat pump.

Why choose this?

  • Cut heating bills by replacing a G-rated non-condensing boiler
  • Improve reliability and safety with a modern, serviced heating system
  • BUS grant support when upgrading to an air source heat pump
  • Gas Safe and MCS-certified installation with full warranty
  • We handle grant paperwork so the discount comes straight off your price

What's included

  • Free check of your current non-condensing boiler and eligibility
  • Recommendation for condensing boiler or heat pump upgrade
  • Safe removal and disposal of your old boiler
  • MCS-certified heat pump or high-efficiency boiler installation
