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 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 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.

Boiler price guide

We can give a rough estimate of how much a new boiler is likely to cost depending on your property. If you’d like a more precise price guide please use our online boiler quote.

Not all boilers are suitable for every situation. For example, a 24kW boiler will produce enough energy for a couple living in a one bedroom property with just one bathroom, but it won’t be sufficient for a 4 bedroom house, with 2 occupants and 2 bathrooms.

Boiler prices vary and the prices shown below are solely for the unit itself and does not include installation or any other components.

Small house, flat or apartment

A small house, flat or apartment, with 1 or 2 bedrooms, a single bathroom and up to 10 radiators, would typically require a boiler output of between 24 to 27kW.

Semi detached medium sized house

A semi detached / medium sized house with 3 or 4 bedrooms, 1-2 bathrooms (main and en-suite) and up to 15 radiators would typically require a boiler output of between 28 to 34kW.

With so many variables affecting the cost of a new boiler it’s important that you seek expert help and advice before getting a quotation. Our Gas Safe boiler specialist will visit your property and assess your current heating and hot water system and help you determine exactly which boiler model is most suitable for you.

We’ll look at your existing central heating system and ask a few questions so we can understand your heating and water requirements, whether that’s likely to change in the future, and provide you with a no obligation fixed price quote within 24 hours.

For each installation we have to consider a number of practical factors such as size or dimensions, radiator replacements, flue length and position, removal of old water tanks – so if you are replacing an old traditional boiler with all of the above installation is likely to take 2-3 days.

After your new boiler installation, you will start saving money on your energy bills and maintenance costs should be very affordable. The amount of money you could save in the long run could go a long way to paying for your new boiler.

You’ll get your first-year annual boiler service for free when you choose us. The annual boiler service must be kept up each year to keep your guarantee valid. Don’t worry, we’ll send you a yearly reminder just in case you forget.

Mike Hex VERIFIED

I've used other local plumbing companies in the past but will continue with Palace Plumbers from now on. The office staff are very helpful and the engineers have been on time every day to install my new boiler.

Meg Moran VERIFIED

Taz, the plumber who visited, was very courteous and managed to fix my shower and toilet in just over an hour. The time went slightly beyond the hour but I wasn't charged any extra for this.

Henry Fullerton VERIFIED

Boiler repair was carried out swiftly. It's been 2 weeks and my heating system is working better than ever. I've already booked up my annual service for later in the year. 2 thumbs up.
