What's in this article?
Did you know that last year over 1.6 million boilers were sold in the UK? Bet you didn't.
That’s a lot of boilers and a lot of brands competing to be chosen by you.
So, it’s not such a big surprise that there’s a lot of confusion when it comes to choosing a new model for your home.
If you've been looking at Baxi boiler reviews and Worcester Bosch reviews, but are stuck trying to decide which brand to choose, this article is for you.
Who are Worcester Bosch and Baxi Boilers?
Founded in the UK back in swinging 1962, Worcester Bosch has been leading the way in the British boiler industry for decades, renowned for their high-quality build and excellent aftercare.
In 1992, the company merged with the German-based Bosch group ad for the last 10 years have won the Which? Best Buy Award.
Baxi is another European brand with a long history in the heating industry, with a manufacturing base in Preston, Lancashire.
Due to the UK based manufacturing hub, their availability of parts and aftercare is also superb.
Warranties & Aftercare Comparison
One of Worcester Bosch’s most enticing selling points is the fact that they don’t just offer a warranty but a guarantee.
Is this just marketing fluff?
Not at all.
A guarantee is superior to a warranty since it’s an agreement from the manufacturer that they will attend your property and repair or replace your boiler as soon as possible.
Most other boiler brands offer a typical warranty with their products, this is a contract to investigate the issue, but not an unconditional agreement to repair the boiler free of charge.
When purchased via Heatable, all Worcester Bosch boilers in the Greenstar Range come with a 10-year loooong guarantee.
If you've read any Baxi boiler reviews you'll have noticed that they only offer a 7 year warranty (not a guarantee) on most of their models, this includes their popular Baxi 600.
Bear in mind that the majority of warranties and guarantees are only valid on the condition that serviced annually and by an approved boiler installer.

The boiler price is often the deciding factor for many when it comes to crunch time.
Worcester Bosch is an award winning and market leading brand, so there is no denying it’s a little more expensive than Baxi overall, but it really depends on the model you choose.
For comparison, for the Greenstar 25i by Worcester Bosch you are looking to pay between £800 – £1000 (that's boiler alone, without installation, flue, accessories or anything else), while a Baxi 600 will cost between £700 – £1000.
Worcester Bosch is slightly more expensive, yet you are securing yourself a 10-year guarantee by an award winning boiler brand. Is it really worth saving a few hundred pounds for a shorter warranty period?
It’s also worth noting that the price will vary depending on the supplier you choose.
Customer Trustpilot Reviews
Awards from third party consumer organisations such as Which? are incredibly trustworthy, but the honesty of genuine users of the product are unarguably reliable.
Fortunately, Worcester Bosch has some of the best customer reviews on Trustpilot and far ahead of any other boiler manufacturer to date.
Worcester Bosch has gained an incredible number of user reviews. As of February 2021, nearly 20,000 customers left a review.
The average rating of these reviews was 4.7 out of 5 stars, quite fantastic for a brand selling in such large volumes. Agree?
Baxi boilers also have some incredible feedback on the platform. As of February, the brand has over 25,000 reviews on Trustpilot.
The average rating of Baxi’s reviews was 4.5 (almost as good as Worcester, but not quite!), a clear indicator of their products quality and the aftercare offered by their team.
So in terms of customer reviews, the brands perform remarkably similarly.
Size (Dimensions, not power)
Many prospective boiler buyers also have concerns about the size of the boiler - will it fit into the kitchen cupboard?
This is particularly important for those with limited space.
Both the Worcester Bosch Greenstar and the Baxi 600 are considered small boilers.
Yet, Worcester Bosch made a boiler exactly for this common concern - the Worcester Bosch CDi Compact, or Si Compact, designed exactly for small spaces like kitchen cupboards.
Both Worcester and Baxi provide their models with conventional, mechanical controls with 24-hour programming and digital controls that allow you to set a 7-day schedule.
Both manufacturer’s offer the ability to utilise smart thermostats too, such as Hive and Nest, allowing you to control and schedule your boiler from the comfort and convenience of your smartphone.
Baxi also have their own uSense smart room thermostat.
Easily controlled via an accompanying smartphone app, the thermostat has a variety of innovative features including temperature modulation and temperature scheduling.
From the uSense thermostat, you can also activate anti-frost protection during cold weather to protect your boiler from frost and prevent it from freezing during the winter months.
The energy consumption feature also allows you to see how much energy your system is using, allowing you to better understand where efficiencies or use could be improved.
Other Notable Features
Here are some of the best features offered by each of the brands.
Some of Worcester Bosch’s most popular features include:
- Installed with the condenseSure siphon, offering boiler frost protection
