The Best LPG Boilers

If you’re actually looking for the best LPG boilers, we’d recommend sticking to top boiler brands. There are cheap LPG boiler brands out there, but the last thing you want to do is save on up-front costs, only to overspend on repairs and the inevitable, early replacement.

Sure, boilers can cost a lot; but their cost is just a fraction of what you’ll pay altogether. With fittings and installation, the total cost can almost double. I’d sooner spend an extra £100-200 on a quality boiler brand that lasts for 7-10 years or more.

Here’s another thing to consider. With a company like Heatable, you can get a Worcester LPG boiler installed for a price that’s similar to what you’d pay for a lesser-known brand. You can get fixed LPG boiler prices from Heatable here.

You can’t really go wrong with products from any of the brands below:

  • Worcester Bosch
  • Ideal Boilers
  • Potterton
  • Vaillant
  • Baxi
  • Vokera Boilers

However, we’ll urge you to consult an LPG installer first, as they can direct you to the optimal boiler for your property. Plus, they typically know about boiler deals at their local merchant.

But before you start browsing through LPG boiler models, you’ll need an answer to the following question:

What kW LPG Boiler Do You Need?

Take 60 seconds to understand what LPG gas boiler size you need (in kW), and this entire process will be much easier and faster.

LPG boilers are grouped in 3 size ranges. In the table below, you can see how boiler sizes correspond to your quantity of bathrooms, bedrooms and radiators:

Boiler Size (kW)

Quantity of Radiators

Number of Bathrooms

Number of Bedrooms

24-27

10 or less

1

1-2 bedrooms

28-34

8-14 radiators

1-2

3-4 bedrooms

35-42

14-20 radiators

2

5+ bedrooms

Keep in mind — this isn’t a one-size fits all approach. It’s a guideline.

Whether you want to fill baths quickly, run taps and showers at the same time, have lots of open space, minimal insulation, or a conservatory, the goal posts will shift.

And that’s why it’s a good idea to get a quote from an LPG boiler installer. An installer will spec a boiler not solely based on your property, or the amount of radiators and showers. They’ll also consider your overall demand for hot water and heating.

Getting slightly confused and incredibly bored? I hear ya’ 😊

Here’s a quick and simple way to get an installer’s recommendation for the best-suited boiler for your property:

  1. Head over to Heatable
  2. Answer a few (anonymous) multiple choice questions
  3. Get boiler recommendations with fixed prices

Heatable are an online boiler installer with great connections to the biggest boiler manufacturers in the UK. Put simply, if you’re going to get the best deal on LPG boiler installation, it’ll be through Heatable.

What Type Of LPG Boiler Do You Need?

Already know what LPG gas boiler you need? Skip ahead to the next section…

There are 3 types of LPG boiler:

  • Combination
  • System
  • Regular

If you don’t want to spend extra cash, you’ll want to stick with the same boiler type you already have. For instance, it’ll cost you extra money to upgrade from a regular or system to a LPG combi boiler.

Once you know what type of LPG boiler you need, you can get an instant fixed price (i.e. NO “extras” on installation day) online using this form from Heatable.

LPG Combi Boiler

With an LPG combi boiler, you’ll have no hot water tank (aka hot water cylinder) or cold water storage — combination boilers heat water on demand. This means you needn’t waste precious space on hot water cylinder or cold water feeder tanks.

Condensing LPG combi boilers are the most popular. They’re usually fitted in small-medium sized properties with 1-4 bedrooms.

The downside to LPG combi boilers is they prioritise domestic hot water over your radiators. So, have a 20 minute shower, and you’ll notice the heat in your home has dropped considerably.

If you have a large property and high hot water demand, it’s likely you’ll need a system or regular boiler. These heat water up prior to use, and store it. That means you’ll always have plenty of hot water, even if you’re using multiple showers and taps at once.

System LPG Boiler

An LPG system boiler combines a boiler with a hot water cylinder. So, it’s suitable for bigger properties (and those with high hot water demand). On the downside, you’ll need to give up some space to store the cylinder.

If your current setup has a boiler and cylinder (but no water storage tank in the loft), you need a system boiler.

Regular LPG Boiler

A regular LPG boiler needs a cylinder AND a water storage tank. So, you’re talking about a lot of space here.

If you have a cylinder, boiler, and a storage tank (often installed in loft spaces), you’ll need a regular boiler.

If your engineer doesn’t think you need a system or regular boiler, there is the option to upgrade to a combi. This will remove the need for water storage tanks and free up space. However, the price of your LPG boiler installation will be much higher with this upgrade, compared to just replacing for the type of boiler you already have.

LPG Boiler Cost

There’s an incredible amount of choice on offer here; each brand has a variety of different models, in a range of price brackets. Some of these prices may surprise you — for instance, a Worcester LPG combi boiler may end up costing less than a Baxi LPG boiler of the same kW output (especially if you look on Heatable).

At any rate, here are the LPG boilers we think are the very best (boiler only, no installation):

LPG Boiler Installation Cost

So, what prices should you expect to see on LPG boiler quotes? There’s no simple answer. If you want the detailed version, we’ve already created a guide to new boiler installation costs here.

Or, you can get a fixed price on screen over at Heatable.

Either way, expect your LPG boiler cost for installation to vary a great deal, based on:

Labour

First, you have labour. Are you using a large national company, or live in an area with a high cost of living, like London? There’s a good chance you’ll pay more than someone using a cheap local installer in the Midlands or the North.

Materials

What additional parts and materials are included in the itemised quote? Does the installer need to factor in extra for additional copper pipe for upgrading the gas main? Are you going for a premium LPG boiler over a cheap one? Are you using existing controls, or are they being updated too?

The list goes on. One thing worth noting is a lot of installers will include a boiler filter, which catches debris that would otherwise damage the boiler. If another installer isn’t including one as part of the price, expect to add around £200 to your quote.

Upgrades

Upgrades can cost a lot of money, too. Whether that’s a gas main upgrade, or you want to switch your regular/system to an LPG combi boiler.

Who Can Fit an LPG Boiler?

There seems to be a bit of confusion when it comes to who can fit an LPG boiler.

You need a Gas Safe registered engineer that has also completed their LPG qualification.

For residential property, that’s CCLP1 PD.

We only recommend companies with LPG boiler installation accreditation, that also offer great value for money. Get your fixed price for your new boiler including installation within 90 seconds from Heatable.
