What Are The Best Boiler Brands To Buy In 2021?

If you’re in the market for a new boiler, check out our top 5 list of the best names in the world of boilers to install in 2021 and make the right choice for your home.

Worcester Bosch

Probably the most well-known brand and most likely the first one that most people think of when asked to think of a boiler brand, Worcester Bosch is always going to make the list for one of the best brands. With competitive prices, exciting new ranges of modern boilers like the Greenstar range and extended warranties if you have your boiler fitted by a Worcester Bosch installer, there’s a reason that this brand is always coming up on top. 

They have won the Which? Best Buy award for their boilers for ten consecutive years, and for a good reason. Their products are reliable, quiet and not the most expensive on the market. Worcester Bosch offers incredible support and aftercare which means that in 2021, they are still top of the list.


A boiler from Vaillant is on average going to cost about the same as one from Worcester Bosch. They have a great reputation, but it’s not as well-known as the reputation that Worcester Bosch has. If you purchase a boiler from Vaillant, they can offer you a warranty between 2 and 5 years depending on the product that you purchase. 

These are not as long-term as the warranties on offer by Worcester Bosch and Ideal, but Vaillant have a good reputation for high-quality boilers and their latest ecoTEC range is proving to be very popular. 


Alpha is rising in popularity with customers, and with a 4.7 out of 5-star rating on Trustpilot, they are proving that their products are high quality. In their range of boilers, you will find prices that will suit you if you are on a budget, and they also offer warranties of between 5 and 10 years. 

Another selling point of Alpha boilers is that their heat exchangers are made of stainless steel, which makes them more durable and more likely to last for a longer period. This should give you peace of mind that the most expensive element of your boiler is built for the long haul.


After winning a Which? Best Buy award for their boilers in 2020, Viessmann has to be on the list for the best boiler brands to buy in 2021. They offer long warranties up to ten years and their boilers have a reputation for lasting longer than average. They also give you the option to purchase your boiler on finance, which is a great option if you have found yourself in an emergency where you need a new boiler but are struggling to front the costs.


A company that is rising in popularity is Ideal, which are now selling over 10,000 units every single year. They offer three different types of warranty so you can choose one that suits you, and these range from 2 years to 10 years. With similar prices to competitors like Worcester Bosch, the only thing that sets Ideal apart is the fact they don’t have as strong a reputation. If they continue the way they are doing, they are bound to be considered one of the premium brand names in boilers, but with a more comfortable price tag attached.


There are some fantastic options that we have covered in this article. If you are still unsure what the best boiler brands are in 2021, rest assured that they are in the list above. Worcester Bosch will always be the most reliable and well-known brand name, but the other brands in this article are an excellent alternative and give you more flexibility on warranties, price and choice of boiler.
