What does brand loyalty really mean these days? For instance, just because your old, failing boiler was produced by a particular brand, doesn’t mean you should necessarily pick that same brand again.

With so many different brands on the market, your choices are wide open, often making the decision to replace your old boiler a very difficult one.

That’s why I’ve been putting together these comparison blogs, where each week I compare the market leading Worcester Bosch boiler brand with other well-known names (last time it was Worcester Bosch vs Glow-worm).

(To find out more about Worcester Bosch, take a look at our recent blog post, entitled 7 Reasons Why Worcester Bosch should be your next boiler)

So, this week I’m going to be looking at Keston boilers to find out just how they compare to the current market leader and Which ‘Best Buy’, Worcester Bosch.

Boiler types/styles available

Much like Worcester Bosch, Keston offers quite a wide range of combi, regular, and system boilers, including a compact range that will fit inside your kitchen cabinet. However, Keston’s boilers have larger outputs and are only really designed for larger homes with outputs upwards of 30kw, whereas Worcester Bosch has boilers to cater all sizes of homes.

Reliability

Keston boilers are fairly reliable, so although you can probably depend on your Keston boiler, they aren’t produced by a mass manufacturer and not all engineers will be familiar with the brand.

Worcester Bosch boilers are known to be one of the most reliable brands on the market, backed up by their market-leading guarantee (more about that below).

Guarantee

Keston boilers only provide a two-year guarantee, which is one of the poorest on the market. The company use a separate agent to provide their warranty service, and have their own appointed contractors for different areas in the United Kingdom.

On the other hand, Worcester Bosch’s guarantee lasts for eight years, and is one of the best no-quibble guarantees on the market.

Reputation

Often favoured by architects and designers when renovating larger homes, Keston’s reputation is sound, and they are known as a niche, premium brand made by a smaller manufacturer.

However, when it comes to reputations, nothing can quite beat Worcester Bosch, as the brand has been voted Which’s ‘Best Buy’ for four years running now.

Cost

Keston boilers tend to be relatively expensive, and definitely not looked upon as a budget boiler. Their large boilers are about on-par with Worcester Bosch boilers, and they mainly sell a lot of regular and system gas boilers.

Other factors

The biggest advantage of a Keston boiler is the ingenious twin-flue system that runs up to 27 metres. This essentially means your boiler can be fitted anywhere in your home.

However, Keston boilers can also be very noisy, which could be a problem depending on where you choose to fit it. Assuming your boiler is fitted in a basement or attic of a larger home, it shouldn’t be noticeable.

However, if you are concerned about noise, Worcester Bosch offers one of the quietest boilers available.

Conclusion

Keston boilers are known as a premium, reliable brand, and at the same price as Worcester Bosch, could make a great choice for your large home. However, the two-year guarantee really lets the side down, and you could end up paying more for expensive repairs later down the line.
