Worcester-Bosch: A Trusted Name in Boilers

Worcester-Bosch is one of the UK’s leading domestic heating and hot water manufacturers. Founded in 1962 as a small engineering works, Worcester-Bosch has grown into a market leader with a reputation for producing innovative gas and oil-fired boilers that are designed for efficiency, affordability and reliability. 

The company has consistently proven their credentials with their flagship Greenstar boiler range which was launched in 2001. Since then the Greenstar range has won a number of awards including the prestigious CORGI’s Boiler of the Year Award for three consecutive years between 2005 and 2007.

The company’s Greenstar range was also voted “Most Reliable Boiler Worcester-Bosch” Best Boiler Cover and “Most Satisfied Customers” by Which? And featured as the Best Buy boiler for nine straight years. It was only recently toppled by Worcester-Bosch’s parent company Vaillant. 

The company has also scooped a number of other awards in recognition of its contributions to the heating industry, commitment to quality, and focus on energy efficiency. The accolades include Top Boiler Brand, Manufacturer of the Year, and Installer’s Choice.

The boiler Worcester-Bosch’s range includes combi boilers, system boilers and regular boilers with energy efficiency always taking a key role in product development.

In May 2019, Worcester-Bosch launched their Greenstar 8000 Lifestyle Range which features innovative technology to maximise comfort, optimise heating and enhance hot water performance. The 12-year guarantee that comes with the Lifestyle range is a testament to how reliable the company views their boilers.

Considerations when buying a Worcester-Bosch Boiler

The Greenstar range from Worcester-Bosch is one of the most acclaimed series of boilers available in the UK. Known for its energy efficiency, the Greenstar boilers have received recognition and awards for their performance and eco-friendly features. 

The company has a diverse range of boilers to cater to various heating needs. This includes combi boilers, system boilers, and regular boilers, providing options for different types of installations and user preferences. But what features and performance indicators should you look for when buying Worcester-Bosch boilers?

Energy-Efficiency

Worcester-Bosch has been a pioneer in the development and adoption of new technologies and typically incorporates high-efficiency features, extracting more heat for less cost. 

The energy-efficient rating (SUBDEK) varies between boilers but ranges between 90-94% which is consistent with other boilers on the UK market. 

Dimensions

Worcester-Bosch combi boilers are known for their compact and space-saving design. Combining the functions of a central heating boiler and a water heater into a single unit, they are ideal for homes with limited space. 

However, it should be noted that dimensions are not consistent. Also, ​​there are different types of boilers, including combi boilers, system boilers, and regular boilers. The most suitable type depends on your heating and hot water requirements and how much storage space you have available. 

Combi boilers are space-saving and provide hot water on demand. They are most suitable for smaller homes that don’t require heavy water use. System and regular boilers may be better for larger homes with multiple bathrooms but require additional storage space for water tanks and cylinders. .

Performance Output in kW

The performance output in kW should match the heating demands of your home. An oversized or undersized boiler can lead to inefficiencies, either by using more heat than you need or not providing a sufficient amount. A heating professional can perform a heat loss calculation to determine the appropriate kW output for your property.

Ease and Cost of Installation

The cost of installing a new energy-efficient boiler should include labour charges for the installation together with maintenance and servicing moving forward. 

Although Boiler Prices are not able to provide precise installation costs, we can say the average installation cost in the UK is between £1,100 – £1,800.

To find out exactly how much you should expect to pay to install a new Worcester-Bosch boiler in your home, take advantage of the Boiler Prices ‘get a quote’ feature. This gives you access to a wide range of suppliers and installers in your local area and should get you the most competitive prices.

Warranty

Worcester-Bosch combi boiler range ensures high energy efficiency and comes with a basic 5-year guarantee at the low end of the range and an impressive 12-year guarantee for their premium line.

Worcester-Bosch Combi Boilers: Compact, Efficient, and Cost-Saving

Combi boilers are by far the most popular boiler range on the UK market. Needless to say, they are the least expensive. In terms of price point, Worcester-Bosch is not the cheapest, but their prices are competitive. 

Prices for their combi boiler range start at £767 and go up to around £2033 depending on the size and specifications.

But combi boilers are also popular because they are highly efficient, compact and practical. They arguably offer the best value for money, although are not as consistent in delivering hot water and heating solutions as other boiler types. Reliability really depends on your heating demands such as how many people use the property and how much hot water you need on a daily basis. 

The Greenstar range from Worcester-Bosch is renowned for its energy efficiency. These boilers are designed to achieve high Seasonal Efficiency of Domestic Boilers in the UK (SEDBUK) ratings, often reaching A-rated efficiency levels.

Smaller homes are well suited for combi boilers. Measuring 710 x 400 x 330mm, the Worcester-Bosch combi boiler range is not the smallest on the market but is still compact enough to fit snugly in most cupboards or under the stairs.  

A key benefit is that combi boilers do not require a separate tank or cylinder to store water. That means these boilers can be comfortably stashed in a kitchen cabinet or under the sink.

Worcester-Bosch says an ErP A++ combi or systems boiler with a 24-28 kW heat output will comfortably heat smaller and medium-sized homes and apartments with one bathroom and up to five radiators. Regular heat-only boilers will do the same job with a lower kW output.

Larger homes with up to four bedrooms and two bathrooms are best served by boilers that exceed 30kW. We recommend consulting with an experienced gas-safe engineer so they can assess the size of your home and your hot water demands. Homes with larger rooms will be best served by a 42kW boiler. 

Homes with five or more bedrooms and multiple bathrooms or an above-average demand for hot water will need a least a 42 kW boiler from Worcester-Bosch, maybe even 50 kW. But rest assured, Worcester-Bosch has you covered. The company manufactures boilers that are suitable for large commercial properties.

Note: the prices listed below are the purchase prices for the boiler only. They do not include installation costs.

Worcester-Bosch Heat Only Boilers: Versatility, Efficiency, and Reliability

Worcester-Bosch regular boilers (also known as ‘conventional’ or ‘heat only’ boilers) are a reliable source for on-demand heating. This type of boiler stores hot water in a separate cylinder, providing a consistent and reliable supply of hot water to taps and showers. This is particularly advantageous for larger households with high hot water demand.

The key benefit with this boiler type is that there is no reduction in flow rate so you can use multiple taps without the risk of running out of hot water (as can happen with a combi boiler). 

Worcester-Bosch boilers utilise existing pipework and radiators which makes them easy to install. You may also be able to integrate them with solar thermal systems if they are also running from existing infrastructure. This contributes to increased energy efficiency and reduced environmental impact.

The only drawback of installing regular heat-only boilers is that you need space to install a water storage cylinder and the boiler unit. An airing cupboard is the obvious choice. Consequently, regular heat-only boilers are best suited for larger homes — typically with an existing heat-only boiler.

Worcester-Bosch regular heat-only boiler prices range from £759 – £1847 with varying sizes and outputs.

Note: the prices listed below are the purchase prices for the boiler only. They do not include installation costs.

Greenstar 8000 Life Regular30 – 50kWHomes with more than one bathroom and high demand for hot water £1,260 – £2,220

Worcester-Bosch System Boilers: Easy installation, efficient heating, and customisable options

Worcester-Bosch system boilers are known for their high energy efficiency. They often feature condensing technology, extracting additional heat from the combustion process, which can contribute to lower energy bills.

System boilers (often referred to as ‘sealed systems’) provide central heating and hot water via a storage cylinder which is usually housed in an airing cupboard or loft. 

Like regular heat-only boilers, this type of boiler provides instant hot water even when more than one tap (and a shower) is in operation. However, there is a drawback. 

The water cylinders in a system boiler have a limited amount of hot water stored for on-demand use. Once the water stored in the tank has run out, you have to wait for the boiler to reheat cold water that is sourced from the main supply. 

Having said that, Worcester-Bosch system boilers are capable of delivering high flow rates of hot water, making them suitable for homes with multiple bathrooms and high hot water demands for a family of five to six people. They may not be suitable for a guest house.

Worcester-Bosch system boilers are energy efficient (like all Worcester-Bosch boilers) and come with at least a 5-year guarantee. Prices range from £824 to £1062 with varying sizes and specifications.

Note: the prices listed below are the purchase prices for the boiler only. They do not include installation costs.

Worcester-Bosch Oil Range – Designed for Homes Not Connected to the Gas Network

Oil-fired boilers are the best option for homeowners who want to live off-grid. This type of heating system is an alternative energy heating system that does not source power from the gas grid. 

However, oil-fired boilers are not as green as manufacturers make out. Yes, they can reduce your CO2 emissions at source but all oil-fired boilers need to be connected to a special outdoor tank that stores the oil, and the oil itself has to be delivered to your home by road. So all things considered, oil-fired boilers are not an eco-friendly option.

That said, if you really want to save the planet, you will need to invest in renewable energy sources. The problem is, that no single renewable energy solution is effective at the minute other than heat pumps (allegedly) and air-source heat pumps cost somewhere in the region of £7,000+ excluding installation costs.

Like Worcester-Bosch energy-efficient gas boilers, the Worcester-Bosch’s oil boilers have secured Which? Best Buy status comes in different types including combi, system and regular boilers to suit most requirements. Prices vary from £1,300 to £2,750, and each oil boiler in the range is backed by a 2-year warranty as standard.

Some Worcester-Bosch oil-fired boilers can be installed indoors, whereas others must be located outside. These types of boilers are identified with the word ‘External’ in their name. 

Below, we’ve listed the full range of Worcester-Bosch oil-fired combi, system and regular boilers and what size of property they best suit:

Worcester-Bosch Boiler Warranties

No matter which Worcester-Bosch boiler you choose, your appliance will come with a manufacturer-backed warranty, ranging from 2 to 5 years in length. The warranty ensures that you won’t pay for any material or manufacturing faults for the duration of the warranty period. 

However, all Worcester-Bosch boiler warranties come with strict terms and conditions which must be respected to keep the warranty valid. Worcester-Bosch offers ‘no quibble’ warranties and sometimes exclusive extended warranties, but you must register the warranty to reap the full benefits. 

Our Worcester-Bosch Boiler Warranty guide explains everything you need to know about your boiler warranty.

Worcester-Bosch Boiler Cover and Breakdown Options

While Worcester-Bosch boilers offer quality and reliability, things can still go wrong now and then. No boiler is immune from problems, which is why it’s so important that you have your Worcester-Bosch boiler serviced every year.

Worcester-Bosch boilers display a fault code or error code on the boiler. The fault code should help your engineer identify and diagnose any problems with your boiler so that they can resolve them as quickly as possible. 

Some fault codes won’t be serious enough to call an engineer, which means you might be able to fix the issue and clear the fault code yourself. Having said that, most Worcester-Bosch fault codes will require the attention of a qualified Gas Safe registered engineer. If your boiler is displaying a fault code, our guide to Worcester-Bosch Boiler Errors and Fault Codes should help you find out what the code means.

Keeping your boiler in good working order is the best way to avoid unexpected and expensive problems. Worcester-Bosch boiler cover, provided by Domestic and General, not only offers you cover for breakdowns and repairs but also comes with an annual service. Annual servicing allows you to have your boiler checked and tested by a Worcester-Bosch engineer and provides you with a detailed report on your boiler’s health, including any issues that need to be dealt with.

Worcester-Bosch Boiler Surveys and Reviews

Customer review sites are where the real story lies when it comes to purchasing or researching all manner of products online. That is certainly the case for boilers because of the high volume of people who leave a review. That means new customers today don’t have to rely on the word of an engineer or the manufacturer.  

Worcester-Bosch has received fantastic reviews from their many, many customers on, Trustpilot. At the time of writing, the company has received over 41,000 reviews and has an impressive 4.6 feedback rating. That is very impressive!

On closer inspection, it’s clear that existing customers say that Worcester-Bosch boilers are not the cheapest option on the market, but they were prepared to pay a little extra for reliability — which incidentally is backed by an attractive manufacturer’s guarantee of between 5 and 12 years. 

These types of guarantees illustrate how Worcester-Bosch boilers deliver a dependable performance, and last for a long time — giving you value for money. Other defining features worthy of mention are how quiet Worcester-Bosch boilers are and how quickly they supply hot running water.

Which? Engineers Review

Which? is recognised as a trusted consumer magazine that offers unbiased appraisals and expert opinions. As we have seen Worcester-Bosch has been a firm favourite amongst their writers over the years. 

The latest Which? review published in December 2023, is equally positive. Worcester-Bosch boilers received a 5-star rating for reliability from customers, although Which? Only gives them an overall score of 4/5. Still pretty good going but they dropped points because some engineers find them hard to repair, but parts are readily available, often on the same day. 

How difficult the boilers are to repair shouldn’t concern customers too much until after the warranty has expired. Engineers do give kudos to the build quality and credit the reliability, Worcester-Bosch boilers typically last well over a decade. 

Which? also reports that Worcester-Bosch rates highly for technical and aftercare support which is lacking across the industry as a whole. Ringing in an overall score of 82%, Worcester-Bosch has improved on the 74% they received in 2018 and appears to be going from strength to strength.

How do Worcester-Bosch boilers compare with other boiler brands?

Worcester-Bosch is proven to be one of the top performers in the UK boiler market and well worth a punt if you’re on the hunt for energy-efficient boilers that represent good value for money. Where the British manufacturer stands ahead of its competitors is reliability, and its boilers often receive positive reviews for durability.

By all accounts, the only boiler Worcester-Bosch that can rival Worcester-Bosch is Vaillant although, Alpha E Tec, Viessmann Vitodens 100-W and Ideal Logic+ are also worth looking into for build quality.

Worcester-Bosch provides competitive warranty periods on its boilers, offering peace of mind to customers. Vaillant, Viessmann, and Baxi are among the brands that also offer generous warranty coverage on their products.

The company’s customer service also comes highly rated, and only a handful of the other top six boiler companies can claim the same, Vaillant and Baxi among them.

Boiler Prices Verdict on the Worcester-Bosch Boilers: 5/5

The Boiler Price verdict and overall rating are based on customer feedback, reliability, value for money and how easy the boilers are to repair including accessibility to parts. 

Gas-safe engineers have vouched for the reliability and parts availability of Worcester-Bosch energy-efficient boilers, and that’s backed up by the flurry of positive reviews on TrustPilot. 79% of respondents give Worcester-Bosch 5 stars. Only 9% left a 1-3 star rating whilst 12% were awarded 4 stars. 

These impressive stats are backed up by Which? readers who left a full 5 out of 5 rating for WB. Which? scores are a good indicator of how many people would recommend a product to their family and friends. 

Worcester-Bosch also has an above-average rating for repairs and guarantees. No company is perfect when it comes to aftercare, but you want to be assured there is a reasonable level of consistency, and WB seems to tick the boxes in that department. 

The moral of the story here is that when you buy a less expensive boiler, you should expect that the parts are cheaper and potentially less reliable than more expensive boilers. 

But it has to be said, the vast majority of Worcester-Bosch customers are satisfied which is a testament to how reliable even their lower-priced boilers are. 

So, why buy a Worcester-Bosch boiler?

Worcester-Bosch has built a strong reputation for producing reliable and durable boilers. It is clear from customer feedback that UK householders trust the brand and regard the British manufacturer as the market leader in the UK. 

The praise is fairly unanimous — and they have a proven history spanning over 60 years that underscores how the company repeatedly manufactured top-quality boilers you can rely on. Customer reviews claim their Worcester-Bosch boiler lasted 25 years! 

As an assessment of the company’s history shows they consistently invest in innovation in order to improve their range of products which has been recognised on numerous occasions with industry awards.  In 2022, the company scooped top prizes for product and customer service

Its much sought-after Greenstar range is designed to be environmentally friendly and energy-efficient, meeting or exceeding industry standards. The majority of boilers are designed with condensing technology, maximizing the extraction of heat from the combustion process and contributing to lower energy bills

In the current epoch, Worcester-Bosch continues to make great strides in ensuring their boilers are energy-efficient and quieter than ever before. The Federation of Master Builders reports the Greenstar 4000 range is “low-maintenance, easy-to-install and easy-to-use…with a fair guarantee”. 

Not only does Worcester-Bosch deliver high-performance products, but has a solid reputation for providing reliable customer support – which is not always the case for top-tier boilers companies or mega-businesses in general. 

So all in all, we have no qualms about awarding full marks to Worcester-Bosch because it’s clear they go that extra mile to be the best.

Worcest Bosch! Sounds all good till something goes wrong. 40 minute wait to answer the phone and that was warm September. Couldn’t give me s service date till February as not an emergency!

After much haranguing someone called me back with late Nomber ! Oh! and it was 7am till 6 or 7 pm so whole day committed for a 1-hour service. Was going to buy a new boiler off them but wouldn’t touch with a barge pole! What happens in a bad winter? Be warned!

I want to replace our old boiler a Potterton Kingsfisher II. I am living in a extended house with 5 rooms and living room. We have 9 radiators and a large family of 7 (most of the time). What kind of boiler is recommended? A combi boiler or one with an extended water tank?
