When this service is the right fit
This service is ideal if your boiler is beyond economical repair, regularly breaking down, or struggling to heat your home evenly. It also suits renovations, property purchases, and landlord upgrades where you want predictable performance and clear compliance paperwork. If energy bills are rising, a correctly sized modern boiler with proper commissioning can make a noticeable difference.
How the work is delivered
The process starts with a practical review of the existing system and what you need from it, such as hot water demand, radiator performance, and control preferences. Installation includes preparing the area, fitting the new boiler, making all required connections, and checking system integrity. Commissioning then confirms safe operation, stable pressures, correct temperatures, and proper response from thermostats and timers.
Handover and aftercare
Once commissioned, you are shown how to use the controls and what to monitor, such as pressure and fault indicators. You receive the relevant compliance paperwork for your records, landlords, or future buyers. For best long-term performance, plan routine servicing and address any system upgrades recommended during installation.
