The Costs, Benefits and Savings of a new Boiler


If you haven’t had your boiler replaced for a good few years, the chances are that it’s not as efficient as it could be. If you’ve got a G-rated boiler (between 50-70% efficiency) and choose to get a new boiler that’s A-rated (at least 90% efficiency), you could save up to £210 a year.

That sounds like a great saving, but what are the other benefits of installing a new boiler? And how much should you look to spend on an energy efficient model?

The costs of a new boiler

A replacement boiler is a significant investment, so it’s not a decision that should be taken lightly. Some models are more expensive than others, and it all depends on how straightforward the install is.

If your Gas Safe registered engineer doesn’t have to move the flue and the gas pipe is the right size, a typical install should cost between £1,800 and £2,300.

There are Government grants available for households with low incomes to get a new boiler for free, but there are strict criteria for receiving the funding, so expect to have to pay for a boiler yourself, whether outright or on a finance deal.

Benefits of replacing your boiler

There are plenty of benefits to getting a new boiler:

  • Cheaper energy bills: As gas prices continue to rise, having the most efficient boiler will ensure that you don’t spend any more than you need to on heating.
  • Happier family: Your home will be warmer and more comfortable, benefiting everyone in your home.
  • Energy efficiency: Your home will be more energy efficient with a new boiler, especially if you draught-proof and insulate your home as well. This will make it more attractive to buyers if you decide to sell up.
  • Do your bit: Help the environment by having an A-rated boiler – you’ll bring down your home’s carbon emissions.

How much can you save with a new boiler?

The amount you can save by replacing your boiler will vary depending on how inefficient your old boiler was, but according to the Energy Saving Trust you can save up to £215 per year if you live in a semi-detached house and your old boiler is less than 70% efficient. Even if your old boiler is between 78-82% efficient, you could save up to £85 a year.
