Worcester Bosch: Company Overview

The company was formed in 1962 in the UK’s very own Worcester, and has only gone from strength to strength. Initially a small engineering works, Worcester Bosch is now one of the market leaders in boilers today. Back in the 60s, oil fired central heating was the norm. It wasn’t until the early 70s that combi boilers were introduced to the country.

In the 1980s, water bye-laws were relaxed and the combination boiler concept was developed even further. In the space of a decade, oil boilers, which were used by 95% of households, were on the decline and gas boilers had started to take over.

In 1992, Worcester Heat Systems joined with the Bosch Group, creating a European business that would become one of the biggest heating names in the world. In the 2000s, Worcester Bosch boilers started becoming more environmentally friendly in ways that would reduce consumers’ energy usage, which included a heat pump range brought out in 2006.

More recently, in 2009, Worcester Bosch boilers received the Royal Warrant from the Duke of Kent, elevating them to one of the highest accolades in the UK. In 2018, the company manufactured its 50,000th boiler. In summary, the company has cemented its position as a trusted brand that millions of people across Europe have come to depend on.

When you choose a Worcester Bosch boiler, you are choosing quality and performance over anything else. Having been in business for many years, you can expect new Worcester Bosch boilers to work efficiently and be covered under their robust guarantee. You can maximise the duration of this by having one of their engineers install it.

Remember that any warranty is void if you don’t have your boiler regularly serviced. This is normally only once a year, but it’s important for the longevity of your boiler.

How Much Do Worcester Bosch Boilers Cost?

The price that you pay for a boiler will never be just for the unit, unless you’re fitting it yourself. As well as the purchase price, you’ll have to be conscious of the installation as well. Engineers for Worcester Bosch boilers can be on hand to install your new heating system, which maximises their guarantee.

Purchase Costs

The more modern Worcester Bosch boilers supplied are built to modern standards. This means that you can expect quality and a lasting source of hot water throughout your property, as well as energy savings and high efficiencies.

Greenstar boilers are some of the best on the market. You can expect regular Worcester Bosch boilers to cost around £2,400, whereas the Ri model is a fraction of this at around £1,100. Their efficient combi boilers are fairly consistent in price at around £1,500. It’s only Worcester Bosch’s regular boilers that come out the most expensive.

Now that you know how much Worcester Bosch boilers cost, how do these prices compare to other manufacturers?

Installation Costs

Installing a new boiler will always vary in cost, depending on where you are and where the boiler will be fitted. The cheapest price for a combi boiler installation is around £600, but even with registered installers of Worcester Bosch boilers, this can be up to £1,200.

  • Fitting a different kind of boiler

  • System clean

  • Smart controls

Some of this could drive up the cost to what you paid for your boiler, at around £1,500.

A Comparison of Worcester Bosch Boilers

Combi Boilers

Combi Worcester Bosch boilers are perfect for smaller properties with low hot water demand. The Greenstar 25i combi boiler, for example, has an output of 25kW, which is enough to power up to 10 radiators. It comes at around £900, which is definitely in the more budget category compared to the modern equivalents listed above.

Combi boilers are more energy efficient as they only heat hot water on demand. There is no need to set heating up times, and the boiler won’t be expelling exhaust gases into the air on a constant basis, unlike other boiler types.

Worcester Bosch combi boilers are compact by design and able to be mounted on the wall or tucked out of sight. They are efficient and smaller than other boilers, which makes buying a combi boiler very attractive to consumers.

System Boilers

System Worcester Bosch boilers heat water and store it in a hot water cylinder, ready for later use. They have a higher power output as they cope with a bigger hot water demand in a household. More modern than traditional (or regular) boilers, they regulate pressure by themselves and work off mains water.

The most budget system boiler from Worcester Bosch starts at around £990. The Greenstar 9i is one of the cheapest system boilers available, whereas external models, such as the Greenstar Danesmoor External, can cost over £3,000.

Regular Boilers

Also known as traditional or heat-only boilers, these generate pressure artificially with the use of a header tank in the loft. They don’t work off mains water, like system boilers do, but can be the most suitable system for an older home. Regular Worcester Bosch boilers also make use of a hot water cylinder with the use of an immersion heater, giving you back-up hot water in the case of a breakdown.

Regular boilers from Worcester Bosch can start at £990 and go all the way up to over £2,000 for the Greenstar Utility.

Gas Boilers

As gas boilers are the most widely used throughout the UK, you can expect the most amount of innovation to have gone into them. Most Worcester Bosch boilers running on gas are rated A and have at least a 90% efficiency rating.

Oil Boilers

The majority of people are moving away from oil boilers as they have one of the biggest environmental impacts of any heating system. For homes that don’t have the luxury of this option, oil Worcester Bosch boilers are incredibly efficient, being rated A under the Seasonal Efficiency of Domestic Boilers in the UK (SEDBUK).

Other Top Boiler Brands

Naturally, you don’t have to settle on a Worcester Bosch boiler. Other manufacturers that are also renowned across the UK include Vaillant, Baxi, Ideal and Glow Worm. The best boilers of the year summarise how they all compare.
