What Is A Gas Boiler?

New gas boilers will have a huge impact on your home. If you’ve never had a new one installed, or it’s been a long time since you last replaced your gas boiler, then you might not know what benefits a new boiler can bring – and what you should look out for.

Gas boilers are normally fuelled by natural gas, although LPG (liquefied petroleum gas) is another option available in locations that do not have a mains gas supply. A gas boiler is usually used to heat water that comes out of taps in your bathroom, kitchen and cloakroom, and to provide hot water for your central heating radiators in your home to keep you warm.

Choose The Right Type Of Boiler

There are three main types of boiler:

Combination (combi) boiler
Conventional or system boiler

The best gas boilers for your home will depend on the size of property and how much you use it. There are different models from a range of brands that cover all price points, making it easy to find a gas boiler perfect for your needs.

How Much Does Gas Boiler Installation Cost?

Gas boiler installation involves more than just the boiler itself being replaced. You might need to move pipes, change the location of the gas boiler itself, and more. When you get a quote for new boiler prices, ask for a breakdown of what’s included, so you can properly compare what’s on offer.

We’ve spoken to the suppliers we work with you give you a estimate on what a quote for a new gas boiler might look like:

 Price Range

The cost of your boiler


Boiler installation cost


Cost of moving pipes


Mechanical flush before installation




The range between the bottom and top prices is huge. This range is caused mainly by the model of gas boiler you choose.

Many homeowners will find a gas boiler to be the best option, which can cost between £625 and £1,250, so you should expect to pay no more than £1,885 to £2,500 when you factor in installation charges.

Mechanical flushes are only needed when you’re replacing a very old boiler system. That means, in probably 85% or more of installations, you won’t need to budget an extra £440 to £535 for that service.

Benefits Of New Gas Boilers

Installing a new gas boiler comes with many benefits, and you’ll enjoy them over the lifetime of the boiler. These include:

Improved efficiency, saving you money on your monthly bills
Taking up less space than your old boiler in many cases
Fewer repair or maintenance bills
More features, such as smart controls

Choosing A Gas Boiler

There are a number of different key factors to consider when it comes to choosing your new gas boiler. Understanding these can ensure you make the right choice, and get the most accurate and competitive gas boiler prices from any quotes you receive.

Here are some of the most important factors to consider:

Dimensions – the height, width, and depth of your boiler. If your replacement gas boiler is going into the same place in your home as where it is now, your installer will probably recommend a boiler that’s exactly the same or very close in size. If you’re moving the boiler to a new location in your home, be sure to tell the installer where you want it to go so that they can recommend the best gas boiler for you.
Flow rate – this lets you know how many litres of water your boiler can handle every minute. The more taps you have around the home, the higher the flow rate you’ll want.
Output – closely connected to the flow rate is the output – measured in kilowatts (kW). To make sure your water is hot when it comes out of the tap or shower, you’ll need a boiler that can easily heat up the amount of water that your household generally needs at all times.
Energy efficiency rating – boiler technology has become very energy efficient in recent years. The more energy efficient your boiler, the lower your gas bills. A-rated boilers will bring the biggest savings, but even B-rated boilers can be worth considering.

Every property is different and all residents will have different needs, but here’s the general rule of thumb installers use when recommending the best gas boiler for your home:

Small properties with up to 10 radiators and 1 bathroom – a 24kW-27kW output boiler.
Medium properties with up to 15 radiators and 2 bathrooms – a 28-34kW output boiler.
Large properties with up to 20 radiators and 2 or more bathrooms – a boiler with an output greater than 35kW.

If you get the right gas boiler, you’ll benefit every year from sizeable savings on your utility bills. Get it wrong and, although you’ll have all the hot water and heating you’ll ever need, you won’t see the savings because your new boiler will cost a lot more to run.
