What You Need To Know About Boilers
A boiler is a staple in any property, providing heat via radiators in each room and hot water for your home. However, it’s easy to get overwhelmed with all the different types and specifications. We aim to demystify boilers, so you have the vital information you need to make the right decision for your new installation. Boilers are not cheap and we want to make sure you don’t pay more than you need to. It’s also vital to choose the right type of boiler for your property and lifestyle to keep your heating bills as low as possible.
First, an energy efficient boiler can significantly reduce your heating bills. The Energy Saving Trust estimates that upgrading to an A-rated system from an old G-rated boiler can save the average semi-detached house between £105 and £300 per year on energy bills. New boilers also tend to be more reliable as well as energy efficient, so while there is a cost to replacing your old boiler, you’ll save more in the long-term with fewer maintenance costs and repair bills on top of lower energy bills. A new boiler is definitely a worthwhile investment.
Next, boiler installation and replacement should always be carried out by a Gas Safe registered installer, and it’s usual to ask for proof before any work is carried out. Every installer working with Compare Companies is Gas Safe certified, so you can be sure you’re working with a reputable boiler company providing quality work which is fully safety compliant.
Boiler Type | Price Range |
Gas combi | £499 to £825 |
Gas system | £512 to £910 |
Gas conventional | £492 to £3,600 |
Oil Combi | £2,057 to £3,191 |
Oil system | £1,335 to £2,407 |
Oil conventional | £1,107 to £3,770 |
What Does A New Gas Boiler or Combi Boiler Cost?
The cost of a new boiler will vary depending on the type chosen, the boiler size, and its fuel or power supply. The cost of running the boiler can also vary and this needs to be taken into account. Here are some sample costs as a starting point. These prices are just for the boiler unit and exclude the installation cost.

Each one has a specific use and are worth considering in some cases. The plumbers we arrange to meet with you will help you choose the most appropriate type of boiler for your property.

A Closer Look At The Different Types Of Boilers
The three main types of boilers used in the UK are:
The installer we arrange to meet you will help determine the most appropriate type of boiler for your property. This may be different to your current boiler if your existing boiler is very old. In most cases, an installer will recommend the same boiler type and use the same location unless something has changed since your old boiler was fitted, such as a house extension.
System Boiler
With a system boiler, most of the hot water and heating system components are contained in the boiler itself. A hot water tank or cylinder is needed but there’s no requirement for a separate cold water tank. A system boiler is a good option for homes with multiple bathrooms or where there is a higher demand for hot water.

Conventional/Heat Only/Traditional Boiler
If your old boiler has a conventional hot water system linked to a hot water cylinder with a cold water tank in the loft, then it makes sense to source a replacement boiler which does the same job. The cold water tank feeds the hot water cylinder and maintains the central heating system’s water level.
Benefits of conventional boiler:
Combination/Combi Boiler Quotes
Combi boilers provide hot water for both the central heating and the taps. When a tap is turned on, the water is heated straight from the mains so there is no need to store hot or cold water in a cylinder or tank. A new combi boiler is a popular choice for many UK householders. Over 50% of new boilers installed in the UK are combi boilers. They are known as combination boilers because they combine heating the water and providing the central heating for the property.
Benefits of combi boiler:

What Should You Think About Before Having A New Boiler Installed?
Although buying a new boiler is never going to be as exciting as buying a new car or booking your next holiday, it is a vitally important home improvement project that will impact your lifestyle and comfort as well as your wallet. This is a decision that needs careful consideration.
1. Always Use A Gas Safe Registered Engineer
Boilers are complex systems that need to be installed correctly to ensure they work properly and aren’t a safety hazard to the people in your home. Always use a Gas Safe registered installer for your boiler upgrade scheme. They’re certified to work with the different boiler systems, and you’ll be able to rely on quality workmanship that’s safe and backed by warranties. Always double check online that your installer is certified before any work begins.
2. Choose A Reliable Boiler
A reliable and energy efficient boiler will save you money in the long-term even if the new boiler cost is higher than you planned for. Cheap boiler models often require more maintenance and repairs and will cost you more in the long run than if you had opted for a more expensive, well-known brand from leading manufacturers.

3. Select The Right Type Of Boiler
Most homes in the UK are on mains gas, and that means there are three types of boilers for you to consider:
A Gas Safe engineer can help you determine which type of boiler is most suited to your needs and property. While there are other fossil fuel heating systems available like oil, if there is a mains gas supply at the property, then this is almost always the best option to consider especially with fuel prices so volatile. If you don’t have a mains gas supply but still want a gas boiler rather than consider oil boilers, then Liquefied Petroleum Gas (LPG) is another option. The gas is stored in a tank at your home.
4. Install An Energy Efficient Boiler
Did you know that many boilers that were state of the art ten years ago would perform badly in today’s tests? If your boiler is more than 15 years old, it almost certainly would fail a modern energy efficiency test.
The boiler accounts for 60% of what you spend each year on energy bills, according to the Energy Savings Trust, so the more energy efficient a boiler is, the more it can help you save on your power costs.
Make use of thermostatic radiator controls which can help keep your home at a consistent temperature, reducing the amount of energy it takes to heat up a cold house each time you need to get warm. Nowadays, smart heating controls don’t require someone to be present in the property. Timers and apps can also be used to avoid heating an unexpectedly empty house, and to put the heating on a little while before you get home.
Don’t forget that you’ll need regular maintenance and an annual boiler service to ensure everything operates at its best and is running at its most energy efficient. Many boiler installation companies sell service packages on top of the boiler installation process and fixed price boiler cover so you’re insured if your boiler breaks down.
