From 2010 to 2013, there was a Government backed scheme which covered scrapping and replacing your old boiler. However, all schemes are now closed, meaning that there is a cost to scrapping and replacing your boiler. This guide aims to help you decide whether it is worth replacing your old boiler.
Why would I need a new boiler?
There are several circumstances where you may need to replace your old boiler. You could be attempting to reduce your energy bills, or it could just be that your boiler is tired and it is time for a new one. However, if your reason is the former rather than the latter, there could be cheaper options out there for you. One option is to install cavity loft insulation or loft insulation to ensure that less heat escapes from your home. Doing this will mean you spend less on your central heating and you will see a reduction on your energy bills.
In the winter months, the cost of heating up your home represents about 60% of your energy bills. Based on a calculation of 25% gas usage, the Energy Saving Trust estimates that installing a new boiler will save the average household £300 on their energy bills, not taking into account the cost of installing a new boiler.
Which boiler and installer should I use?
First of all, if you have decided to get a new boiler, you should decide which type to go for.
- Fuel type: The majority of UK households have a gas boiler, however there are other options such as oil or a wood burning stove fitted with a back boiler.
- Boiler type: Do you want to replace your old boiler with a combi boiler, which will provide heating and hot water, or a heat-only boiler?
- Efficiency: If you choose a gas boiler, heating your home will account for 60% of your home’s CO2 emissions, so your choice of boiler will affect not only you, but the environment.
- Heating controls: Heating controls will allow you to choose which temperature your heating system is operating at. You can ensure your heating is only on at the times and in the rooms that you need it to be.
Installing your boiler
You should never attempt to install a replacement boiler yourself. You should always choose a registered engineer from the Gas Safe Register to do the work for you. Which? recommends getting quotes from several different boiler installers before choosing the one that is right for you. They say to always get a minimum of three quotes and ensure that they include call-out fees and other hidden costs. You may find that some installation companies such as British Gas and other energy companies choose an engineer for you, rather than allowing you to choose your model. If you have a specific model in mind, it may be worth making this clear to your energy company before you go ahead and get a new boiler.
The cost of boiler installation varies, depending on how much work is required, where you live and who you employ for the job. You could pay between £540-£660 to replace a gas boiler in the same position as the old one, or £1,440 for trading in a gas boiler for a brand new combi boiler.
