Gas Boiler Installation

Boilers that are over ten years old waste a lot of valuable energy, in terms of cost and environmental impact, in fact many older boilers convert as little as 60% of the fuel they use into heat.

Looking for cost efficient heating? You should be aware that current building regulations state that any replacement or new gas-fired boiler must be a condensing boiler. Older boilers convert as little as 60% of the fuel they use into heat which has a big impact on your home heating bills and the environment.

We specialise in the installation of condensing boilers and renewable energy products from Worcester, using the latest technology available. Modern condensing boilers improve efficiency to over 90% which could save you a minimum of 30% per year on your home heating bills, which represents a big saving over the lifetime of your boiler.

Depending on your heating and hot water demand there are different types of condensing boilers that are available, please follow the link for any questions you might have regarding the main boiler types.


Our experienced and helpful staff will always be happy to assist you.

Types of boiler

Typical savings & the types of central heating systems How much could you save?

This will depend on how old and inefficient your existing boiler is.

Typical annual saving based on your present boiler rating

G ( < 70%) £300 plus
F (70-74%) £200 plus
E (74-78%) £150 plus
D (78-82%) £105 plus

These are estimated figures based on installing a new A -rated condensing boiler in a semi-detached home with three bedrooms.

Modern boilers are more efficient for several reasons, but their main advantage is that they are all condensing boilers. All well-maintained boilers burn their fuel very efficiently, but they inevitably lose some heat in the hot gases that escape up the flue. A condensing boiler has a bigger heat exchanger, so it recovers more heat, sends cooler gases up the flue and is more efficient.

Installing a new boiler

The right boiler

Most old gas boilers are regular boilers they have a separate hot water cylinder to store hot water, rather than providing it directly from the boiler. When you replace your boiler you have a choice of buying a new regular boiler, and keeping your hot water cylinder, or buying a combi boiler that doesn't need a cylinder.

A regular boiler is actually more efficient than a combi at producing hot water in the first place, but then some heat is lost from the hot water cylinder, so a combi may be more efficient overall.
