An efficient boiler is essential in every home, generating the hot water needed for relaxing bath times and to keep the whole house cosy. But while it’s arguably the single most important item in your home, you probably won’t appreciate its importance until something goes wrong – that’s why it’s essential to not only make sure your boiler is well maintained, but that it gets replaced when the time comes.

When should you consider boiler replacement?

A well-maintained boiler should last about 15 years before it needs replacing, so if yours is over 10-years-old, it’s probably worth saving up for a replacement.

You should also consider getting a new boiler fitted in the following circumstances:

  • It’s beyond repair – If you’re boiler breaks down, it doesn’t necessarily need completely replacing, and it might just need a new part. But if a qualified engineer tells you it’s beyond repair, then it’s time to compare boiler quotes and get a new one installed.
  • You need more control – A good boiler should give you total control over the heating in your home, but if those controls aren’t programmable it might be worth considering a new boiler installation. You might be able to get away with fitting a new thermostat, so make sure you consider your options before committing to getting a new boiler fitted.
  • Your energy bills are too high – If a gas boiler provides the heartbeat of your home, it will account for about 60% of your energy bills, according to figures from Energy UK. So, if it’s not working as efficiently as it should be, replacing it is an effective way to help lower your inflated energy bills. If any of the following describes your boiler, it’s definitely worth replacing it as part of any household energy efficiency measures:

    • It has a ‘dry cycle’ – While many modern boilers switch off when your home reaches the required temperature, some old boilers have a ‘dry cycle’ – a system whereby it instead sends heat to an ‘overflow radiator’, which then continues to throw out heat your home doesn’t need.
    • It has a continuous pilot light – Older boilers have small flame, known as a pilot light, which constantly burns to show the boiler is working. Although it only uses a small amount of gas, it’s still an unnecessary waste of energy.
    • It’s not wall-mounted – New boilers are wall-mounted, so if yours is fitted to the floor, it’s most likely an older, and less efficient, model.
    • It’s G-rated for efficiency – All homes now need to have an energy performance certificate before they can be sold, which rates its energy efficiency. If your boiler has a low energy efficiency rating, it’s worth getting a new installation, especially if you’re looking to sell up.

Why compare boiler prices?

Modern condensing boilers are more efficient, and have bigger heat exchangers, meaning they can recover more heat, which means they can make a huge difference to the cost of your energy bills.

Whatever the reason for your boiler replacement, it’s important to make sure you’re getting the right boiler for your building, and also that you’re paying a fair price.

But what type of boiler is best for you?

What types of household boilers are available?

There are three main types of household boiler, they are:

Combination boiler

More commonly known as combi boilers, these are the most popular type of boiler as they provide a continuous supply of heat and hot water, without the need for water tanks or cylinders, meaning they’re a great space-saving option.

Advantages of a combi boiler Disadvantages of a combi boiler
Constant heat and hot water May see a drop in water pressure if using multiple taps or appliances
Space-saving Installation can be tricky and more expensive
No need for a water tank -

System boiler

Also known as sealed system, these units don’t need a water tank but do require a water cylinder, which is usually housed in an airing cupboard.

Advantages of a system boiler Disadvantages of a system boiler
No loss of water pressure when using multiple taps or appliances Hot water is neither instant nor constant – you could run out of hot water and then need to wait for it to reheat
No need for a water tank You’ll need room for a water cylinder

Conventional boiler

Also known as open vent or regular boilers, these are an older style of boiler that need both a water cylinder and water tank.

Advantages of a conventional boiler Disadvantages of a conventional boiler
No loss of water pressure when using multiple taps or appliances Hot water is neither instant nor constant – you could run out of hot water and then need to wait for it to reheat
- You’ll need room for a water cylinder and a water tank

Condensing boilers

Although not strictly a specific type of boiler – you can have a condensing conventional boiler or a condensing combi boiler – condensing boilers capture and recycle some of the heat that can escape from the flue of non-condensing boilers. This means they produce more heat without using more energy, and are a more energy-efficient option.

If you’ve had a new boiler installed since 2005, it should be a condensing boiler.

How much should boiler replacement cost?

New gas boiler prices can be expensive, and you can reasonably expect to pay anything between £500 and £2,500 for a new system to be fitted. But with so many different brands on offer, not to mention the different sizes and types, it’s important to compare a range of quotes, to make sure you’re getting the right boiler installed at the right price.

How much money could you save with a new boiler?

Although new boiler installation costs can be expensive, fitting a more energy-efficient system will save you money on your energy bills, but the amount you save by upgrading your boiler will depend on how old and inefficient your existing boiler is:

Old boiler rating Annual saving* How long will take to pay for itself?
G (<70%) £300 7 years
F (70 – 74%) £200 9 years
E (74-78%) £150 11 years
D (78% - 82%) £105 17 years

*The calculations above are based on installing a new A-rated condensing boiler and full set of heating controls in a gas-heated, semi-detached gas heated home with three bedrooms, using an average 17252 kWh gas a year at a cost of £666 a year.

How to choose a new boiler

Boiler prices can vary depending upon the type and size of boiler you want, and the brand you choose, as well as the difficulty of the installation and the overall boiler fitting cost, so it’s always best to run a new boiler cost comparison before you buy.

It also pays to do a bit of research, so you know exactly what you need when it’s time to buy. So, when choosing a new boiler, consider the following:

  • Choose your fuel from gas, oil, LPG, wood-fueled and biomass
  • If you have mains gas, then a gas boiler is usually the cheapest heating system for you
  • You can either choose to go with a regular boiler or a combi boiler - combi boilers can deliver hot water at any time of the day, but regular boilers have the advantage of being able to deliver hot water to more than two places in the house at once.

When choosing someone to fit your boiler, you can go with an independent installer or an energy provider. New boilers fitted by energy providers will often be the more expensive option, but may include additional benefits such as boiler care packages and smart controls so you can switch your heating on from your phone.

If you choose an independent installer, make sure they are fully qualified and Gas Safe registered - a poorly installed gas boiler won’t just be inefficient, it could also be highly dangerous. Not only could a gas leak cause an explosion, it can lead to deadly carbon monoxide poisoning.

That’s why it’s always best to speak to an expert before you get your boiler fitted. To request a quote, simply fill in the form at the top of the page and we’ll get back to you with up to four, free, no-obligation quotes so you can choose the deal that best suits your needs and budget.
