Which boiler brand is the best?

Without a doubt, finding the top boiler manufacturers is crucial. So when choosing a manufacturer, you need to be very careful. There are even more boiler brands in the UK apart from the above list, some reliable and some not. Moreover, each offers different products and services, making it hard to decide. So before you buy, compare quotes from different companies. This can take time and be stressful if you’re not familiar with boilers and brands.

Why consider a new boiler?

Well, regular non-condensing boilers use gas or oil and aren’t very eco-friendly. They waste energy and can lead to high bills. But new condensing boilers are a better option. Without a doubt, they cost more upfront, but they’ll save you money in the long run. Furthermore, you might qualify for government incentives, like free boilers under schemes like eco4. These boilers use condensing technology and are more efficient, meaning they’ll cut down on your energy bills

What’s a boiler grant?

A boiler scheme is a big program run by the government to help people with their heating.  For example, the Eco4 scheme involves major energy companies giving free boilers to low-income households.  Next, there’s the Boiler Upgrade Scheme (BUS), which offers grants to homeowners in England and Wales.

These grants help cover the cost of installing a heat pump or biomass boiler, which can be really expensive.  With BUS, you could even get cash, up to £7,500, for installing an air-source heat pump. As a result, you can make a big difference in how much you pay overall.

Which boiler brands are excluded from the grant?

Well, the thing is, no specific boiler brand out of the top boiler manufacturers list is left out of the grant. But, you know, those older non-condensing boilers made by many UK brands aren’t covered. Moreover, they’re kind of outdated, burning fuel and wasting energy by letting hot gases escape up the flue. That’s why they’re less efficient and costlier to run compared to newer condensing models.
