When this service is right for you
This service suits you if your current boiler is unreliable, inefficient, or no longer economical to repair. It is also a good fit if you want stronger hot water performance, more responsive heating control, or a simpler set up that removes the need for a separate hot water cylinder. Landlords often choose a planned replacement to reduce breakdown risk and support compliance planning.
How the installation works
You start with a survey to confirm sizing, flue route, condensate disposal, gas supply suitability, and the condition of your heating circuit. The installation is then scheduled with a clear scope of work, and the changeover is completed with careful protection of the work area and a tidy finish. Finally, the boiler is commissioned and tested, controls are configured, and the system is checked for safe operation.
After installation: handover and ongoing value
You receive a clear handover on how to use your heating and hot water controls efficiently, plus the key documents for your records. You can then maintain performance and reliability with routine servicing, and address any system balancing or radiator issues that become apparent once the new boiler is running.
