Back boiler replacement
A gas back boiler usually sits behind a fireplace and supplies heating and hot water. The survey checks the existing system, the proposed replacement location and any work needed to safely decommission the old appliance. Final equipment and the scope of work are confirmed after assessment.
Non-condensing boiler replacement
If your gas boiler is over 20 years old and non-condensing, it may meet the heating criteria for this offer. We check the make, model, heating system and property before confirming funding.
What is ECO4?
The Energy Company Obligation is a government energy efficiency scheme delivered through obligated energy suppliers. Boiler replacement may form part of a wider package of improvements, depending on the home’s needs and scheme rules.
Why upgrade an inefficient boiler?
- A suitable modern system can use less energy to provide heating and hot water.
- Improved heating controls can help you manage room temperatures and heating times.
- A replacement can reduce reliance on an ageing appliance that is becoming difficult to repair.
Running costs depend on the property, system design, energy prices and how you use your heating.
