Worcester Bosch Gas Combi Boilers: Price Range

First, whom or what is a combi boiler?

Combination (or combi boilers) are by far the most common type of boiler in the UK, installed and used in as many as 70% of homes. Modern A rated combi boilers offer over 90% efficiency and provide both on-demand hot water, and heating in one compact unit.

Imagine Usain Bolt was your postman, but he also did your bins. You'd be getting two in one, fast. That's a combi boiler.

They are ideal for properties with limited space since they can easily be installed in tight spots and their high efficiency helps you maximise energy use. Worcester Bosch also offers fantastic customer service all backed up by lengthy guarantees. Yep, guarantees, not warranties.

Worcester Bosch Gas Regular Boilers: Price Range

Woah, Woah, Woah. What's a regular boiler?

Worcester Bosch Greenstar i BoilerWorcester Bosch also has a comprehensive range of regular or conventional boilers, like combi boilers they can provide homes with both hot water on demand and heating. However, instead of a single unit, they consist of a boiler, a hot water storage cylinder and water tanks that are installed in the loft which take up valuable space.

Regular boilers are typically more suitable for larger properties (suits you, sir) with multiple water outlets e.g. multiple bathrooms since they can keep up with the additional demand.

That wealthy neighbour with three en-suites and a snazzy car on the drive - yep - they're a regular boiler user.

Prices for a standalone Worcester Bosch regular boiler range from between £700 to £2000.

Again, it's important to note that's the price for the boiler alone. To get a fixed price on a Worcester Bosch regular boiler which includes installation and everything you need, click here.

Worcester Bosch Gas System Boilers: Price Range

SYstem Boiler CylinderSystem boilers or “sealed system” boilers provide both hot water and heating and like regular boilers perform well at providing adequate flow rate to multiple outlets simultaneously. The hot water they generate is stored in a large storage cylinder, which typically requires more space than a combi. 

Note, with system boilers, there's no need for additional cold water storage tanks in your loft. This means there's more room to hoard old board games such as scrabble, which is always a bonus.

The major downside of a system boiler is that if all the water stored in the cylinder is used, there'll be a waiting game for more - and that's one boring game. It's certainly not scrabble.


Prices for a standalone Worcester Bosch system boiler range from between £800 to £3500 and are available in multiple different sizes. Again, this is for the boiler alone. Not flue, no controls, no labout, nada.

You can get a fixed price (including installation and everything you need) on a Worcester Bosch system boiler by using this calculator.

Why should I buy a Worcester Bosch boiler? Give me one good reason.

Worcester Bosch is the most well-known condensing boiler brand in the UK, a highly respected name amongst homeowners and engineers alike. 

But, why? Why are they known for all the right reasons?

#1 They're award-winning boilers: Voted Which? Best Buy for 10 consecutive years

Worcester Bosch Which? Best Buy

As one of the most credible and respected consumer awards - it's an award, unlike others, which you simply can't buy.

The brand won the “best buy” award based on feedback from actual real humans (not pretend ones). They also gathered feedback from over 100 installers. Moreover, the brand's boilers received several high 5-star ratings the consumer choice organisation considers most important to consumers, including full marks for their build quality and availability of parts and spares.

You can check the latest deals on Worcester Bosch boilers here, and see how the brand compared to another market leader in our Worcester Bosch vs Vaillant post.

#2 CORGI’s domestic heating product of the year


The Worcester Bosch Greenstar Range is their pride and joy. It's their first born and if they were to have an only child, the Greenstar would be it.

When it comes to efficiency, these A-rated boilers are one of the most efficient central heating boilers available, helping you to save energy and money on your heating bills.

It is for these reasons, that the Greenstar Range has been awarded CORGI’s domestic heatingproduct of the year for several years in a row. 

And no, this award has nothing to do with the Queens dogs.

#3 Availability of parts

As the Which? Best Buy Award has already established, Worcester Bosch has a superb reputation when it comes to availability of parts, which is extremely important if you do need to repair your boiler quickly.

This could mean one of two things - their boilers break down often, or, they've been around so long that everywhere stocks them. We're pretty confident that it's the latter. Hopefully.

#4 Market-leading aftercare

Worcester Bosch’s aftercare has also earned itself a reputation for being among the best in the industry.

Again, although already mentioned in the Which? Bst Buy Award, we think it is important to highlight this since amazing aftercare can turn a bad boiler day around and prevent a small inconvenience turning into something much worse. 

#5 The Worcester Bosch warranty

Worcester Bosch Guarantee

Unlike many other competing boiler brands, Worcester Bosch does not just offer a warranty but instead a guarantee. 

But, why? What is the reason for this snazzy wording?

A guarantee is an agreement from the brand that they will attend your property and repair or replace the boiler within a reasonable timeframe. 

Most other brands just offer a warranty as standard, this is an agreement to investigate the problem, but is not an unconditional agreement to fix or repair it for free. 

Heatable offer an exclusive 10-year guarantee on all Worcester Bosch Greenstar gas boilers we install.

#6 Worcester Bosch Customer Reviews

Worcester Bosch TrustPilot

Sure, a trusted, third party organisation like Which? is credible, but nothing quite compares to the honesty and feedback of genuine buyers and everyday users of the product.

When was the last time you wrote a positive review about a company? Never, I bet. They're hard to get.

Thankfully, Worcester Bosch has some of the best customer reviews of any other boiler brand in the industry.

Side note, if you fancy a laugh, go read some of British Gas reviews.


Need to know the cost of a new boiler, quick? Find out what replacement you need along with costs (takes 60 seconds).

On TrustPilot, Worcester Bosch have racked up an incredible amount of reviews. As of August 2020, over 17,000 customers left a review. Mind-bending.

The brand has an average rating of 4.7 stars out of 5, incredible for a company selling in such huge volumes.

Worcester Bosch Error Codes

No matter how reliable or award-winning a boiler brand, none of them are completely perfect and from time to time, boilers will experience issues and require repairs.

Gremlins can reside in award winning products too, you know.

For that reason, it’s vital that you have your Worcester Bosch boiler serviced annually, not only will this ensure everything is in working order, but it is also advised to ensure your boiler is safe and without one, your guarantee is likely to be null and void.

It quite literally won't be worth the paper it's written on.

In the event that your boiler is experiencing a fault, typically an error code will be displayed on the boilers interface. Although not entirely reliable, the codes are displayed to help gas engineers identify the root cause of the problem, so they can be prepared and consult the boilers technical user manual for further assistance. 

Common error codes for not so common errors

Not all fault codes are equal, some indicate worse problems that require professional assistance from an engineer, while others can indicate a minor issue that can be remedied quite quickly by yourself.

For example, if your boiler is losing pressure, you can top that up yourself.

But, if your boiler reeks of gas, you'll need an expert.

Here's some commong codes..

Worcester Bosch Fault Likely Error Code
Pressure too low/high A1, CE 207, H07, 224V, 1017W, 2970B
Pilot light issue (not lighting) EA, F7, FA, EA227, F7 228, FA306
Heat Exchanger error 2963 B, 2964 B, 2966 B, 2967 B
Fan Fault C6, T2, C6 215, C7 214, C1 264
