Why buy a new boiler?
You might want to think about buying a new boiler if:
- You’re moving home – your new property may not have a boiler suitable for your needs, it could also be out-dated and inefficient
- You’re renovating – improving the comfort and energy efficiency of your home should be your first priority when making any home improvements. Ensuring you have a new, efficient boiler to keep your home warm and supplied with hot water is top of the list and can boost the value of your property
- Your current boiler is over 10 years old – boiler technology has advanced greatly over recent years, so it’s likely that if you bought yours over 10 years ago it’s not as efficient as it could be. The Energy Saving Trust (EST) says that replacing an old boiler with a new A-rated model and improving your heating controls could save you up to £300 a year on your fuel bills and cut your household carbon emissions by 1,220kg

- Gas Safe registered engineer for new gas boiler installation

What should you look for in a new boiler?
1) Firstly, make sure that you don’t need planning permission to install your new boiler – this may be necessary if you live in a listed building or need to install a new flue outside of your home
2) To satisfy building regulations, make sure your new boiler is A-rated or at least 88% efficient as judged by the Seasonal Efficiency of Domestic Boilers in the UK (SEDBUK) scale
3) It’s a legal requirement that all new boilers are condensing models. The difference between a condensing and non-condensing boiler is that condensing boilers convert more waste heat into energy, saving you money and helping the environment. If a boiler engineer deems your home unsuitable for a condensing boiler (this is very rare), you will receive a certificate to prove you can install a non-condensing mode
4) Make sure you install proper heating controls along with your new boiler as per part L of building regulations. This means installing, at the very least, a good thermostat
5) Choose between a regular system boiler and a combi boiler. System boilers have a cylinder to store hot water in and are good for big homes whereas combis heat water as needed and therefore don’t need a water tank. Consider a combi if you live in a small property
New boiler grants
Before you buy a new boiler, check whether you’re eligible for a grant towards the cost. The following schemes could provide you with cash towards your new boiler:
- The Scottish boiler scrappage scheme provides £400 towards new boiler costs
- The Warm Front scheme provides up to £3,500 for English residents who meet eligibility criteria. The Warm Homes scheme operates a similar service for those in Northern Ireland while the Fuel Poverty scheme helps Welsh residents out with the cost of buying a new boiler
- All energy suppliers are obliged offer customers grants and discounts towards the cost of new boilers; so ring around to see what kind of deals you could receive
- It’s always worth contacting your local authority or Home Improvement Agency (HIA) to see if you qualify for a boiler grant

Why is a grant only for people on benefits, what about people who are first time buyers and pay there taxes!
