New Boiler Beginners Guide: Top 5 tips to know when buying a new boiler

So you need a new boiler? We’ve got you! Whether you’re installing one into your home for the first time, or replacing an old one, buying a new boiler is a big purchase. It’s one that you need to get right from the get-go, or else you could lose a lot of money in the long run! There’s loads of information online regarding how to choose the right new boiler for you, which can get quite confusing. So, below is our brief guide on how to go about buying a new boiler, with 5 things you need to be doing. 


When it comes to boilers, the general rule is; the higher the quality of boiler you buy, the longer it will last, however, it will eventually need replacing. A typical boiler lifespan is between 10-15 years, but depending on the make and model, they can become less efficient from the 8 year mark. 

Before we talk about finding a new boiler, let’s ask if you really need one. We like to save money as much as the next person, but there comes a time where a new boiler is worth the investment. As we know, the older the boiler is, the more likely it will develop issues. Often these regular breakdowns will tend to cost you more money to repair than replace. You will begin to get very friendly with your heating engineer! Sound familiar? If so, keep reading!

In this case, getting a new boiler installed is the most cost-effective thing to do. Other good indicators that you need a new boiler are if: 

  • Your heating bills are increasing 
  • Your boiler is breaking down regularly
  • Repairs are more expensive than the potentials cost of new boiler 
  • You want to sell or rent the property (new boiler = improved efficiency rating!)


1. Do your research

There are several different types of boilers, such as system, condensing, and heat-only boilers; not to mention the various brands, designs and features. If you don’t know anything about boilers, you’ll need to do a bit of research to help you narrow down on the choices. It’s important to find out the different options available to you – the below videos may help, but we are always on hand to chat though any queries you have too.

2. Work with a budget

The choice of boiler, in most cases, largely depends on cost. Make a narrowly flexible budget and stick to it. You may also have to consider additional installation costs. As with anything, the more you spend, the higher the quality of the new boiler you will receive. Spending a bit more, or investing in a boiler care plan, could save you on repairs in the future. If you’re in need of a rough estimate in order to make your budget, click on this link for a quick boiler quote.

3. Shop around

Get at least three different quotes from leading boiler vendors. Compare the quotes and settle for the one with the best value. Remember that the cheapest quote is not always the best deal. Check for hidden details and charges to make sure that you are getting the best value for your money, and ask about the boiler warranty.

Think about quality too – We only install boilers from industry leading manufacturers. The Worcester Bosch boilers were rated Which? Best Buy for quality and reliability in September 2019.

4. Choose your installer

New boiler installation can be complex and requires skill and experience in the field. Size up the boiler installation companies in your area and select the most reputable and credible installer. For gas boilers, check that your installer is a Gas Safe registered engineer. Oil boilers must be installed by a OFTEC technician. You can check an installer’s credentials online on the Gas Safe register, and ask to see their ID’s in person. 

Keep in mind that most boiler installation companies also deal with general plumbing and heating jobs. Ask about the services offered; some will even extend discounted boiler repair and maintenance services. For more information about the new boiler services we offer, check out our summary video.
