Confused? Here’s The Cost Of Installing Central Heating.

Confused about gas central heating installation costs? Our 2018 cost guide has everything you need to know BEFORE you get quotes.

Or, your renovating a property and there’s no gas central heating at all so you’re looking around at quotes?

In the next 5-minutes, we’ll explain the cost of installing central heating, and the small print you need to watch out for in heating installation quotes.

That’s the long version. If you’d prefer the short version…

How Much Does Central Heating Installation Cost?

Expect to pay £3,500-£4,500 to install new central heating. This includes a branded combi boiler, copper pipework and labour. Prices will increase or decrease depending on the size of your property, and the type of boiler you choose.

Where To Compare Heating Installation Quotes

Get itemised quotes from multiple installers, that’s going to give you a much better chance of getting the best deal. We’d always get quotes from local installers (you can do that here), as they tend to be 10-20% cheaper than national installers.

Electric, Oil, or Gas Central Heating?

Oil is only used in properties that are “off the grid”. Electric boilers, whilst popular, are certainly not cost-efficient. You could end up paying 2-3x the amount in your annual energy bills with an electric boiler, when compared with a gas boiler.

Our Heating Installation Cost Guide

So, you should expect to pay £3,500-£4,500 for an average installation. But, what makes a £3,000 installation, and what makes a £6,000 installation?

To help you figure that out, we’ve split our guide into quick sections.

Costs vary, mainly based on what’s already in your property. That includes an existing, pipework, or simply starting from scratch.

Does Your Property Already Have Pipework?

This is the most important question to answer. It can mean the difference between saving and spending thousands of pounds. Installing new pipework from scratch is time consuming and incredibly costly.

If you don’t see any radiators, or you are using electric heaters, there’s a good chance there’s no pipework. You need a whole new central heating system.

We hate to be the bearer of bad news, but the quotes you’re going to receive are not going to be cheap.

Skip to the section below “The Cost Of Installing Central Heating And A Combi Boiler – No Current Pipework”.

If there’s a gas boiler, oil boiler or radiators already installed in your property? Good news.

The pipework for your central heating is already there. And, there’s a good chance the radiators don’t need replacing. Even if they do, as the pipework is already in place, you’ll be saving lots of time and a tonne of money.

Skip to the section below “The Cost Of Installing Central Heating And A Combi Boiler – Pipework Present”.

If you’re considering new radiators (not always a terrible idea, as newer radiators are much more efficient than older ones), you can jump over to our detailed guide on radiator installation costs here.

The Cost Of Installing Central Heating And A Combi Boiler – No Current Pipework

There are a tonne of factors that will dictate the installation cost.

For instance, what size boiler do you need?

A low-end 24kw combi boiler could be as cheap as £500, but a high-output 42kw combi boiler could be £1,500 or more. And, that’s without labour.

A Ideal Logic Plus 30 is a worthy candidate for 3-4-bedroom properties with 1-2 bathrooms with reasonable hot water demand.

The full cost of central heating installation, including a 30kw Ideal Logic Plus combi, 6-10 new radiators, valves and all pipework should be in the region of £3,650-4,100 + VAT.

The Cost Of Installing Central Heating And A Combi Boiler – Pipework Present

If you’re property has fallen into the second bracket and already has central heating pipework, that’s excellent news.

You’re not actually having a full central heating system installed; it’s just a boiler swap (and possibly, a few minor upgrades).

There’s a good chance the radiators are already where you want them, and pipework to the radiators and boiler is present.

Let’s use the same boiler example as above. Assume you have a 3-4-bedroom property with 1-2 bathrooms and reasonable hot water demand. An Ideal Logic Plus 30 will be suitable.

The cost of copper tube and labour makes up most of a central heating installation price. So, you’ll be saving big time.

Again, there are a range of factors that affect combi boiler installation costs, but we’d be expecting to pay £1,750-2,100 in this scenario; including all materials and labour.

Why Do Central Heating Installation Quotes Vary So Much?

We’ve all seen the news articles. British Gas quoting £6,000 or more for a central heating installation.

But, let’s not slate them for the sake of it. News can be easily manipulated and there are plenty of properties where a £6,000+ price for central heating is more than reasonable. As we’ve already mentioned, the cheapest gas combi boilers are around £500, but a large oil boiler could be as much as £3,000. And, that’s not going to lead to a £3,500 installation quote.

That said, big companies do tend to attach a larger price tag to their installations, and this can be £750-£2,000 more than a local Gas Safe installer in many cases.

Always get 2-3 quotes, you can get them from local qualified installers here. This will give you a better idea of what a reasonable price really is.

What Does A Central Heating Installation Quote Include?

You’ve got 3 quotes. All installers seem trustworthy, and you’ve checked their numbers on the Gas Safe Register.

So, go with the cheapest, right? Not necessarily.

Always get written quotations detailing everything that is included with your central heating and boiler installation.

If you don’t want to get stung, here are some things you’ll want included in your heating installation quote:

  • A magnetic system filter with system inhibitor. This protects your central heating system
  • For those with existing pipework, a hot flush at the very least. This will get rid of sludge build up (which passes through the boiler, and can cause problems)
  • If you are in a hard water area, a scale reducer
  • Price inclusive of controls (thermostat etc)
  • Is any warranty on labour included?

Things That Will Increase The Price Of New Central Heating

And, here are a few things that will increase the cost of a central heating installation or boiler quote, so you know the installer isn’t pulling the wool over your eyes:

  • Moving radiators
  • Installing a boiler in a new location
  • Any additional pipework
  • Upgrading the gas main in line with current Gas Safe standards
  • Purchasing a higher quality boiler, we’ve detailed combi boiler prices here
  • Changing the flue from horizontal to vertical (or vice versa). This requires drilling holes in walls, and cementing afterwards
  • Converting a “system” boiler (uses a hot water cylinder) to a combi boiler system

Accredited Central Heating Installers & Warranties

If you want to get maximum warranty from your heating and boiler installation, do your research first.

A typical example is Worcester Bosch’s warranty. Their basic warranty starts at 5-years. This will jump straight to 7-years (on the exact same boiler) if you use a Worcester Accredited Installer.

Some Worcester boilers have up to a 10-year warranty, this drops to 8 if you don’t use one of their installers.

Which Boiler Should You Install?

If you’re like most homeowners, there’s a good chance you want to get a boiler installed by the most well-known brands. But, don’t discount other leading brands in the industry. Many offer on-par quality and warranty, at a reduced cost.

One recommendation we’d suggest you head towards, are Ideal Boilers. I’d avoid the Logic, simply as it has a short warranty. But the Logic Plus has a warranty of up to 7 years, while the Vogue has a warranty of up to 10 years.

Unlike Worcester, you don’t have to pay extra for a compact boiler (i.e. the Worcester CDI Compact), as all Logic Plus and Vogue boilers will fit in a standard kitchen cupboard as standard.

And, another recommendation would be the Baxi 600 compact boiler. It’s a new release from Baxi that offers excellent value for money. Buy an Ideal or Baxi 600 over a Worcester Bosch, and you’ll have a few extra pounds notes left after your central heating installation is completed.
