Worcester Bosch Boiler Prices

Worcester Bosch boiler prices start at around £836, for the Greenstar 2000, which is a regular or conventional boiler. The company’s most expensive model, the Greenstar Heatslave II External combi boiler, costs about £2,520.

There are upwards of 40 Worcester Bosch boilers to choose from, several of which offer a choice of power outputs. The boiler that’ll best suit your home will depend on a number of factors, such as the size of your property and the number of bathrooms it has.

Worcester Bosch makes combi, regular (or conventional), and system boilers, and the tables below list the typical prices of its different models.


Worcester Combi Boiler Prices

A combi (short for combination) boiler heats water directly from the mains whenever a hot water tap is turned on. This means that, unlike a regular boiler, a separate hot water storage cylinder or a cold water storage tank isn’t needed.

Combi boilers are a very energy-efficient option, because the water is heated instantly rather than stored in a cylinder. They provide on-demand hot water for both radiators and taps, and are the most popular type of boiler in the UK.

Worcester Bosch Conventional Boiler Prices

Conventional boilers, typically found in older properties, produce hot water for radiators via a cylinder – the kind that’s often in an airing cupboard. The source of the water is a storage tank, which is usually in the attic.

Worcester Bosch System Boiler Prices

System boilers don’t use a storage (or feed) tank because they heat water directly from the mains. They also have in-built hot water components, avoiding the need for a water tank. However, a system boiler does require a cylinder for storing hot water.

Worcester Boilers' Installation Prices

The price of your boiler installation will depend on a number of factors, including the size of the property, the type of boiler being fitted, and your location.

For the installation of a new combi boiler that’s replacing an existing one, you can expect to pay about £600. If the current heating system is especially old it may require new parts, such as a mechanical flush, which can cost an extra £500, approximately.

If you want to change your style of boiler, out-of-date materials and equipment will need to be removed as a result.

This could include a hot water storage cylinder and cold water storage tank, among other things. If fresh plumbing is required, this will add to the overall cost, too. All of these factors could easily land you with a £1,500 bill.

A Worcester Bosch boiler

Since most companies offer free, no-obligation quotes, it makes sense to get around three valuations before committing yourself to an installer. You’ll then have the opportunity to take on board the advice provided by each engineer – and compare prices.

While combi boilers are usually simple to fit, installation costs will go up or down based on the size of the unit and whether or not any radiators need to be replaced.

The length of the flue (which safely vents gases) will need to be taken into account, too.

Labour costs will be greater if you need a water tank and/or hot water cylinder to be removed. For more information on what’s involved, refer to our combi boilers guide.

Many boiler brands allow customers to buy directly from them. Since this is not possible with Worcester Bosch, your engineer will act as a go-between. Accredited heating engineers are Gas Safe Registered, meaning they'll meet all minimum safety standards.

Be sure to check that your engineer registers your new boiler with Worcester Bosch so that all aspects of the guarantee are in force immediately. This should happen as a matter of course.
