Who Are Potterton?

Potterton are a UK company that’s been in business since 1850. They’re known by homeowners and installers alike for reasonable prices, high performance, top-notch reliability and the use of top quality components.

Nowadays, Potterton are part of Baxi Heating (another top UK boiler brand), and Baxi in turn, are part of BDR Thermea Group. It’s all very confusing, but the key takeway is this — 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, the boiler type you have (combi, system, etc.), and most crucially, on your hot water and central heating system setup.

The core Potterton regular, system, and combi boiler range comprises:

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

Then, there are the  Potterton Gold and Titanium ranges:

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

All the boilers above come in a variety of different kW outputs; like I said — something for everyone. Generally speaking, Potterton boilers are known to be reliable. And, all of these models have a high energy efficiency rating, so you stand to see a reduction in your energy bills if you’re replacing an old, non-condensing unit.

Combi, System, or Heat Only Boiler: Which Potterton Boiler Do You Need?

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 like, to choose your home water heating system.

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

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

  • Warranty required
  • Budget
  • The type of boiler you have (combi, system, heat only)
  • Whether you have a hot water cylinder and a water tank
  • The size of your property and home
  • The size of your heating system
  • Your domestic hot water demands
  • Number of towel rails and radiators
  • Where you want to install the boiler (i.e. kitchen cupboard, garage, airing cupboard, utility room, etc.)

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

You can book in quotes for Potterton boilers here.

Next, we’d suggest you compare them against Worcester Bosch prices. Typically, you’ll get a better price for your boiler and a longer (10-year) warranty with a Worcester Bosch.

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 combi boiler and system boiler 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 power outputs being similar, the main thing to focus on is the warranty period that protects the boiler. The warranty on the Titanium 24kW Combi is 7 years, whilst the Worcester Bosch 25i offers 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 similar to Potterton’s.

Both boiler warranties are good. If you’ve read any of our other boiler reviews, you’ll know we recommend at least a 5 year warranty 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 a Potterton boiler is comparable in terms of reliability and quality to a Worcester equivalent, the boiler prices are good. They’re are premium boilers, but at the lower end of the range.

Potterton Boiler System Installation Cost

However, note that the cost of the boiler is only part of what you’ll pay. Usually, it makes up less than 50% of the overall installation cost.

Typically, we’d expect a 24-30kW combi installation (by a Gas Safe engineer) to cost in the region of £2,100 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. At the time of writing, we got quoted just £2,040 for the new, crème de la crème Worcester Bosch Greenstar 4000, 30kW. You can get your own fixed price quote right here on your web browser by filling in Heatable’s anonymous, 90-second questionnaire.

Should You Choose a Potterton Boiler or a Worcester Bosch?

It goes without saying that when buying a new boiler, Worcester Bosch is a brand most homeowners think of first. So 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 new Worcester Bosch Greenstar 4000 will cost about the same, or a little more, to install than a comparable Potterton boiler. That said, the Worcester will come with a 10-year warranty — that’s 3 extra years you won’t need to worry about paying out-of-pocket for repairs.

Note, however, that we used local installer prices to get the Potterton boiler estimate, and Heatable prices for the Worcester Bosch alternative. So:

Now, 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 surveyed to get the most suitable boiler recommendation.

A Note on Potterton Boiler Warranty and Performance

We’ve mentioned a few times just how vital a boiler warranty is. Compare prices on a boiler with a 2-year warranty versus one with 5 years, and you’ll see that you can save around £100-£200, or, on occasion, even more.

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

As the cost of a new Potterton boiler only makes up around 40-50% of the overall installation cost, it makes sense to spend a little extra to get a boiler with a long warranty — 5 year at least. And if there’s ever an option to extend the boiler’s warranty, that’s something you should investigate.

This is why we recommend Worcester Bosch boilers so often — they always come with a long, 10-year warranty when installed via Heatable.
