Upgrading an older boiler is one of the most effective ways to improve heating efficiency, reliability and peace of mind. We recently completed a Combi Boiler Installation New Forest project in a self-contained annex, replacing a failing unit with a high-performance Worcester Bosch model backed by an impressive 12-year guarantee.
This installation followed on from previous work we had carried out at the same property, where we had already upgraded the boiler in the main house. The client returned to us because they valued consistent workmanship, honest advice and long-term reliability.

About This Project
This project took place in The New Forest, where the property included a separate annex used for family and guest accommodation. The annex was running on an older combi boiler that had begun losing pressure repeatedly. Despite attempts to repair it, the system was deemed beyond economical repair.
Given the heating requirements of the annex and the property’s use of LPG, we recommended installing a Worcester Bosch Greenstar 8000+ 32kW LPG combi boiler.
The work included:
- Safe removal and disposal of the old combi boiler
- Installation of the new Worcester 8000+ 32kW LPG combi
- Upgrading pipework where required
- System flush to ensure optimal performance
- Installation of modern controls for improved efficiency
- Full testing and commissioning
The result was a seamless Combi Boiler Installation New Forest, restoring reliable heating and hot water to the annex. Most importantly, the client now benefits from a brilliant 12-year Worcester Bosch guarantee, offering long-term reassurance and protecting their investment.
