Boiler Prices

Choosing the perfect boiler for your home is probably one of the most important decisions you’ll make this year.

We appreciate that buying a new boiler and upgrading central heating system is a considerable purchase. That’s why we aim to provide you with as much information as possible to help ensure that you understand the factors that affect the cost of a new boiler installation.

How much does a new boiler cost?

Although you can get a relatively cheap combi boiler installed for well under a £1000, it might not be the best choice in the long-term to meet your requirements.

The price of your new boiler will depend on:

  1. The size of your property
  2. The number of bathrooms
  3. Your heating and hot water requirements
  4. Your existing central heating system

What affects the price of a new boiler?

There are 2 main factors that determine the price of a new boiler.

  • Brand (or manufacturer)
  • Energy output

The boiler output, or energy, is measured in kilowatts (kW) and the more energy a boiler produces the higher the purchase price will be.

Additionally, the higher the energy output of the boiler the bigger the boiler dimensions will be. This could determine the boiler location and will need to be taken into consideration before any truly accurate boiler installation quotation can be given.

What are the best boiler brands to buy?

There are a couple of clear front-runners in today’s boiler market.

Worcester Boilers

Worcester Bosch boilers have achieved Which? Best Buy Status for the past 8 years running, and are the only boiler manufacturer to have received the award. Worcester Bosch boilers are the best boilers on the market and although their price point is a little higher the likelihood of a breakdown within the first six years is highly unlikely, offsetting the initial purchase cost against potential future breakdown bills, that you might be burdened with if you choose another boiler brand.

Vaillant Boilers

Vaillant boilers are a popular choice with consumers because of the combination of cost and reliability.

There are a myriad of other boiler manufacturer’s to choose from but we only fit these brands because we believe they offer the best all-around quality and value for money. What we don’t do is install inferior quality products that are likely to break down within a short period of time. In due course, this results in a negative customer experience for you and reflects negatively on our workmanship.
