When you invest in a new Worcester Bosch boiler in Surrey, one of the biggest benefits is the manufacturer's guarantee. But what's the difference between a 10-year and a 12-year warranty, and how do you make sure yours stays valid? As Worcester Bosch accredited installers in Guildford, we break it down for you.
The Worcester Bosch 8000 Range: 12-Year Guarantee
The Worcester Bosch 8000 range is their flagship boiler line, and when installed by an accredited installer like Surrey Heating, it comes with an exclusive 12-year manufacturer guarantee. This covers both parts and labour, giving you over a decade of complete peace of mind. The 8000 range is designed for larger homes and offers superior performance and efficiency.
All Other Worcester Bosch Ranges: 10-Year Guarantee
For all other Worcester Bosch ranges — including the popular 4000 combi and the Ri Heat Only — you receive a 10-year manufacturer guarantee when installed by an accredited installer. This is still one of the longest warranties available in the boiler industry and provides excellent long-term protection for your investment.
How to Keep Your Warranty Valid
1. Annual Boiler Service
Your warranty requires an annual boiler service by a Gas Safe registered engineer. Missing a service can void your guarantee, so it's essential to keep up with yearly maintenance. We offer comprehensive servicing across Guildford, Woking, Godalming and all of Surrey.
2. Use a Gas Safe Engineer
Any work carried out on your boiler — whether it's a repair, service, or installation — must be done by a Gas Safe registered engineer. Using an unqualified tradesperson will immediately void your warranty.
3. Install a System Filter
Worcester Bosch requires a magnetic system filter to be installed alongside the boiler to qualify for the extended guarantee. This protects your boiler from sludge and debris, extending its lifespan.
What Does the Warranty Cover?
Both the 10 and 12-year guarantees cover parts and labour for any manufacturing defects. If your boiler develops a fault due to a manufacturing issue within the warranty period, Worcester Bosch will send an engineer to repair or replace the affected components at no cost to you.
