Boiler installations can be complicated and expensive so it's important that you have all the relevant information before any decisions are made regarding buying your new boiler. Here's the key things to firstly take into consideration before buying a new boiler:

1. Choose a reliable boiler, with a trusted brand

Essentially, the more reliable your new boiler is the less unexpected costs you're likely to fork-out on expensive repairs. Do your research on the experience boiler owners have had with particular boiler manufacturing brands so you have a good understanding of which brands you can trust to provide a reliable boiler. Don't risk being left suffering from cold showers and freezing cold home by going for the cheapest boiler available as often this means it could be considerably lower quality and lower manufacturing standards.

2. Your engineer should be Gas Safe registered

Always check that your chosen installer is Gas Safe registered. As long as you choose a reliable and trustworthy heating engineer with positive reviews, they'll be an incredibly useful source of information and advice when buying a new boiler. They'll also ensure that your system complies with current building regulations, and will make sure you get all the documentation to prove this. In choosing the correct boiler for your home, you'll have a system in place which is easier to use and could be cheaper to run.

3. What type of new boiler will suit my home and lifestyle?

Most homes in the UK have mains gas, and there are three main types of gas-condensing boiler to choose from:

A qualified heating surveyor or engineer will be able to inform you on the different types of boiler and provide you with a suitable recommendation based on your property and your hot water usage.

4. An efficient new boiler may benefit you in many ways

If your current boiler is an old model, typically over 15 years old, then replacing it with a modern gas-condensing boiler could help you save money on your energy bill. Heating accounts for approximately 60% of what you spend in a year on energy bills[92] so having an efficient boiler is really important. All new boilers are condensing which means they have a large heat exchanger to recover more heat from the hot gases that escape up the flue and sends cooler gases up the flue. Sometimes the flue gases get so cool that the water vapour in the gas condenses out, and even more energy is recovered from the condensing vapour.

5. What the right size boiler for my home?

Boiler sizing is generally based on the heating and hot water capabilities of the boiler and the physical size of your boiler. Different boilers have different performance levels, so you need to ensure that you install a boiler which will efficiently cope with your demands for heat and hot water. Overworking a boiler that is too small for your home could be damaging to the boiler and shorten its lifespan, whilst a boiler that is too big could cost you more than necessary. The size of boiler you need will mostly depend on how many bathrooms and radiators you have, and how many people you live with. This is something your heating engineer can help you with.
