Boiler brands
Worcester Bosch is one of the names homeowners ask for most when they replace a boiler. If you have your heart set on one, or just want to know whether it suits your home, this page covers the practical side.
Worcester Bosch sells its gas boilers under the Greenstar name, with combi, system and regular (heat-only) versions in different outputs. The Greenstar 4000 is a widely fitted combi, with higher-numbered models adding features such as larger displays and connected controls. Check the manufacturer's own site for current models, as ranges are updated regularly.
Worcester Bosch runs its own accredited installer scheme, and the length of manufacturer warranty can depend on who fits the boiler and on registering it. If an extended warranty matters to you, check the terms on the manufacturer's site and ask any installer whether they qualify.
Whatever the brand, the boiler must be fitted by a Gas Safe registered engineer, registered with building control and serviced every year to keep the warranty valid.
Fitting a Worcester Bosch boiler follows the same steps as any good installation: a survey, cleaning the system, fitting a filter, commissioning and explaining the controls. An annual boiler service keeps it running well. If you are deciding between brands, our boiler installation page explains how Chris helps you choose.
Boiler price varies by model and output, but labour, flue, controls and any changes to pipework often matter just as much. Our new boiler cost guide explains what drives the total. For a written price for your home, use our new boiler quote page or call 07429 632804.
If you already have an older Worcester boiler that is playing up, replacement is not always the answer. Many faults on boilers of any brand come down to a single part, such as a fan, diverter valve or pressure sensor. Our boiler repairs page explains how Chris finds the fault and talks through the options before any work starts. If the boiler is well past its best, with repeated breakdowns and parts becoming hard to find, that is when a new Greenstar or another model starts to make more sense. Either way, you will get a straight answer.
Common questions
Clear answers before you arrange a visit.
Smaller combi outputs in the range can suit flats with one bathroom. The deciding factors are hot-water demand and space, which Chris checks on the survey.
A magnetic system filter is good practice with any new boiler, and manufacturers generally expect the system to be cleaned and protected.
Sometimes, but new controls often make better use of the boiler. Chris will explain whether yours are compatible.
Worcester Bosch has an installer search on its website. Gas Safe registration can be checked separately on the Gas Safe Register.
