Are you looking for the best combi boiler for your home?

When many of my customers start their boiler hunt, one of the first places they turn is consumer magazine ‘Which’, and their annual survey based on scores from customers AND engineers alike.

And the one brand that stands out most of all? Worcester Bosch, having won Which’s ‘Best Buy’ six years running – the brand recently achieved the maximum star rating in five of the six total categories for their gas boiler range, with an overall score of 79%.

In order to get these results, 10,779 boiler owners were surveyed, but that’s not all – the magazine also asked Which Trusted Trader heating engineers.

The 2016 survey hasn’t yet been released, but below, I’ve gone into more detail about exactly why Which continues to rate these boilers so highly every year.

Brilliant gas boilers

In Which’s 2015 survey, Worcester Bosch was awarded the highest overall score for their Greenstar gas boiler range – that’s 4% above their nearest competitor.

What’s even more impressive is that every single gas boiler in the range was awarded a ‘Best Buy’ – that’s a staggering 33 boilers overall, including combi, regular and system boilers!


Worcester Bosch boilers are made to last, with no known common errors or faults with their boilers – something not every boiler manufacturer can match. It’s one of the reasons I recommend their boilers to my customers, as I know they can be left to run quietly in the background for years to come.

Their longevity is also reflected in the brand’s market leading guarantee, which I’m going to talk about more below.

Customer satisfaction

With extra long guarantees, accredited installers and trained engineers dedicated to the brand when it comes to managing call-outs, it’s clear to see why customers are so pleased.

However, for the past five years, Worcester Bosch’s own service plan has also received the highest customer satisfaction score of any national plan currently available in the UK.

Build quality

Worcester Bosch are known as a forward-thinking brand that puts a lot of thought into their premium boilers. All of their boilers are made using high quality components that are designed to prevent leaks, breakages and frozen condensates, for a hassle-free existence.

They’re also built in a way that they’re easy for engineers to service, which is why working on them is never too much of a chore.

Easy to source parts and spares

Because Worcester Bosch boilers are manufactured in the UK, parts are always readily available and easy to source – so, there’s no having to wait for weeks on end until your essential boiler part is shipped over.

And because parts are so easy to come by, they don’t cost the earth!


So, now you know why Which loves Worcester Bosch’s Greenstar gas range, as they provide some of the best combi boilers, regular boilers and system boilers on the market today! So, if you’re looking for a gas boiler, look no further than Greenstar.
