Our review of Potterton boilers is going to cover:

  • Who are Potterton?
  • The current boiler range from Potterton
  • Potterton boiler prices (and how they compare with Worcester Bosch)
  • Which boiler system we’d choose to install

Who Are Potterton?

Potterton boilers are a UK company which have been in business since 1850. They’re known by homeowners and installers alike for reasonable prices, high performance, exceptional reliability and the use of top quality components and services.

Potterton are part of Baxi Heating (another top UK boiler brand), and Baxi in turn, are part of BDR Thermea Group (all very confusing). BDR have a global turnover well in excess of £1bn, so they really know what they’re doing when it comes to boilers.

Potterton Boiler Range

From combi boilers to system boilers to heat only boilers, The current Potterton boiler range has something for everyone and every home. The boiler model you choose depends on your budget, your home, number of radiators, the warranty required and the type of boiler you have (combi, system etc).

The range of Potterton boilers is made up of:

  • Promax Store Boiler
  • Promax System Boiler
  • Promax Ultra Boiler
  • Ultra Heat Boiler
  • Assure Combi Boiler
  • Assure Heat Boiler
  • Assure System Boiler
  • Promax Combi

That’s the core offering of boilers from Potterton. To add to confusion, they also offer a Gold and Titanium range:

  • Potterton Gold Combi Boiler
  • Potterton Gold System Boiler
  • Potterton Titanium Combi Boiler
  • Potterton Titanium Heat Boiler

And, they all come in a range of different KW outputs.


Combi, System, Heat Only: Which Potterton Boiler Do You Need For Your Home?

As you can see from the lists above, there’s plenty of choice with Potterton boilers. And, that makes choosing a high performance boiler for your home slightly difficult.

The good news? You don’t have to trawl through output specs, compare warranties, services and the likes to choose your home water heating system.

The easy option is to use this boiler size calculator here, which will list the most suitable boilers for your home at the top of the screen (plus, a fixed price).

Then, local boiler installers will be able to spec a boiler for you, considering:

  • Warranty required
  • Budget
  • The type of boiler you have (combi, system, heat only)
  • The size of your property and home
  • The size of your heating system
  • Number of towel rails and radiators

They’ll then be able to give you an inclusive price quote for the boiler, all parts and accessories, and the cost of installation.

You can book in quotes for Potterton boilers here. We’d suggest comparing them back to back with Worcester Bosch here. Typically, you’ll get a better price for your boiler and a longer (10-year) warranty with a Worcester.

Potterton Boiler Prices

There’s little use listing the 100s of prices for all the different boiler models, as that doesn’t really give a gauge as to how Potterton boiler and boiler system prices compare to other leading brands like Worcester Bosch.

That’s why we’ve used a quick example; the Potterton Titanium Combi 24kw compared with the Worcester Bosch 25i.

With outputs being similar, the main thing to focus on, is the warranty that’s offered with the boiler. The warranty on the Titanium 24kw Combi is 7-years, with Worcester’s 25i being up to 10 years. We’d always go for a longer warranty, and you’ll see here the prices for the Worcester with a 10-year warranty, are basically the same as Potterton’s.

Both boiler warranties are good. If you’ve read any of our other boiler reviews, you’ll know we recommend a 5 year warranty as a minimum for your boiler system.

A quick search online shows the following boiler prices:

Potterton Titanium Combi 24kw price: £770

Worcester Bosch 25i price: £911

So, considering Potterton is comparable in terms of reliability and quality, the boiler prices are good. They’re are premium boilers, but at the lower end of premium.

Potterton Boiler System Installation Cost

But, the cost of the boiler system, is only part of the story. Usually, it makes up less than 50% of the overall installation cost.

Typically, we’d expect a 24kw installation to cost in the region of £2,000 including flue, extensions, accessories and any other fittings in the system.

That’s where Worcester Bosch can compete because of their deals with online boiler installation companies like HEATABLE. Naturally, HEATABLE are getting Worcester boilers ridiculously cheap. So, at time of writing, you’d be able to get a Worcester 25i (10 year warranty, rather than the 7 years of the Potterton Titanium), from £1,770.

Here’s the fixed boiler price we got; you can go and get your fixed price in less than 90 seconds here.

Potterton Boilers Or Worcester Bosch Boilers?

It goes without saying that when buying a new boiler for your home, Worcester Bosch is a brand that most homeowners think of first. The question is, should you install a Potterton boiler, over a Worcester Bosch equivalent?

In the example above, the options between boilers are clear cut. In general, a Worcester Bosch 25i is going to come out around £100 cheaper, than the 24kw equivalent from Potterton. More importantly, you’ll be able to get up to 3 years MORE warranty on a 25i boiler, than you would with the Potterton.

But, the boiler prices relate to a local installer fitting a Potterton, and HEATABLE fitting a Worcester. If you were to get quotes from local boiler installers for both brands, it’s likely that the Worcester boiler is going to be £100-200 more expensive than a Potterton boiler.

Put simply:

The problem is, not all boiler installs are that simple. If you’ve got an oil, gas, LPG or electric boiler, have an extremely large property or home, or need a compact appliance like a combi boiler, you’ll need to get your property spec’d to get the most suitable boiler.

A Note On Boiler Warranty and Performance for Potterton

We’ve mentioned a few times just how important boiler warranty is. Compare prices on a boiler with 2 years, over one with 5 years, and you’ll be able to save a tantalising £100, £200 or more.

But, boiler warranties are set by manufacturers for a reason. There’s a good chance after the boiler warranty expires, that’s the most likely time the performance of the boiler will start failing — that’s just how the boilers are designed. After all, no boiler manufacturer is going to set a 5, 7 or 10 year warranty, knowing they’ll have to fork out hundreds of pounds on repairs during this time.

As the cost of a new Potterton boiler only makes up around 40-50% of the overall installation cost, it makes sense to fork out a little extra, to get one with a long warranty; 5 years as a minimum. And, if there’s an option to extend the boiler’s warranty, that’s something that’s worthwhile investigating too.

And, that’s why we recommend Worcester boilers so often, as they come with a straight up 10-year warranty when installed via HEATABLE.
