Weighing up the costs and options

Exactly how much you can expect to pay will of course be determined by the size, complexity and type of central heating installation you go for.

Generally speaking, you’ll be looking at an installation bill of between £350 and £1,000, which comes on top of the costs of the parts.

Gas or electric central heating?

Gas central heating is by far the UK’s most popular and highly-recommended choice for central heating. The reason is that when considering how much it is to install central heating and how much the running costs are for gas and electric heating units are, gas central heating almost always works out cheaper than electric.

Other options include LPG and Oil central heating systems, though gas again comes cheaper. Gas units are also ideal for homes located in remote areas of the country, when there is no electricity available

Furthermore, gas central heating systems have the benefit of providing hot water the whole day.

In terms of annual running costs, the heating bill varies massively, depending on the usage and property size.

Electric –  £2,000

Gas – £800

Oil – £450

Gas LPG  – £750

A tailored tariff from an electricity supplier could of course bring the seemingly excessive costs of electric central heating down a little, though gas still remains the most cost-effective by far.

How much it is to install gas central heating depends greatly on the size of the unit, the complexity of your home, the time it takes to install the units and your personal preference regarding where and how the installation should take place.

Installing a new gas central heating system is more cost effective than using an old system because it will save you a lot of money on repairs in the long run. Also, many companies offer installation discounts when you purchase new units.

How much will a new central heating system cost?

If an outright refit of the whole job lot is required, the cost to install central heating will again be determined by the system and specifications. You need take into consideration the cost of the boiler, the radiators and controls, the pipework and labour. To get a rough idea of the average cost to install a new central heating, estimate that you need to pay around £3,500 – £4,500 for a three-bed property.

To help you estimate the cost of a new central heating, we have created a list with the cost of the common jobs.

Gas central heating installation costs

Gas is the most popular fuel used to heat in the UK, whether. The cost of course will depend on the size of your property and the number of radiators that need to install.

  • A single story building with 3 radiators is around £2,200
  • A two story building with six radiators is around £3,000

There are two main types of gas boilers, condensing conventional boilers and condensing combination boilers.

  1. Conventional gas boiler

This type of gas boiler system requires two water tanks, one, usually kept in the loft, is the ‘cold water storage tank’ (which refills using cold water mains) along with a ‘small feed and expansion tank’. Water from the storage tank provides water to the cylinder – which is usually located in the airing cupboard – the condensing central heating boiler heats the cylinder and makes the cold water hot. The cylinder can then provide the house with hot water via taps and a pump will move this hot water through pipes to heat the radiators.

  1. Condensing combination gas boiler

Combination gas boilers are economical and can provide your home with a continual supply of hot water and will deliver hot water as fast as the cold taps. However the flow rate may be reduced if more than one tap runs at the same time. Combination gas boilers heat water instantaneously and directly from the mains, so this eliminates the wait that storage cylinders may often incur. It also rids the need of a cold water storage tank. A pump circulates the hot water through the pipes and heats up the radiators.

Electric central heating costs depend on the tariff charged and the electricity company you are with. The most economical tariff is a 7 or 10 that use storage heaters that come on at night for cheaper prices. Electric central heating might not be the cheapest heating technology but you save money on installation and servicing costs.

System components and design

Central heating

Central heating solutions facilitate to have a central unit that generates heat which can be used for various other sub-systems which would be in need of heating solutions. There are widespread applications of central heating systems and it in huge demand, which enables you to enjoy warm and cozy temperatures at your place during chilly winters. Read on to know more about the usage of central heating in different areas and what it costs to install central heating and all the components that you will require for an effective heating system.


central heating boiler

A central heating boiler supplies hot water throughout, never having you to wait for the same. A single boiler can have several outlets which can supply hot water to kitchens, bathrooms etc. There are various types of boilers available in the market such as combination boiler, open vent boiler and system boiler. By having this installed, one can enjoy hot water at all times from a single centralized heating boiler.

The size and type of your boiler has the greatest effect on the cost of new central heating systems because it is by far the biggest component that is required for effective central heating.


There are various types of fuels which can be made use of for central heating facilities. Natural gas, electricity, oil, charcoal and renewable fuel sources can be used as fuels for central heating solutions, depending upon the requirements of the user.

These fuels could also have an effect on the cost of central heating installation because extras such as gas canisters or charcoal containers should also be installed at your home, especially if you want your home to have a neat and tidy appearance.


Flues are chimneys that serve as a vent for the fumes to move out which produced during the operation of central heating boilers. It is essential to have a good quality and efficient flue in place for the boiler, as the fumes might prove to be hazardous, if not vented out properly, by causing overheating and explosion of the boiler. The flues may be concealed or visible openly, based on the installation approach followed. However, regular servicing and maintenance of the flue has to be carried enable the smooth functioning of the boiler; thereby avoiding any untoward incidents. The flue you decide upon will greatly affect how much it is to fit central heating, especially if you want a concealed flue that is built into the walls.

Hot water cylinders


Hot water cylinders are used to store the water heated from a boiler and it stays insulated; thereby keeping the water hot for several days. Also, water present in the hot water cylinder can also be heated by subjecting it to different heat sources.

There are two types of hot water cylinders available: Vented hot water cylinders; which are connected using a vent pipe to a cold water tank and unvented hot water cylinders; which are pressurized to maintain water pressure which can be used to supply hot water at a high pressure.The size of hot water cylinders vary for different boilers and increasing the size of your hot water cylinder will result in an increased fee of installing central heating but might be worth the extra amount if your household requires a lot of hot water or heating.



Radiators are useful in central heating systems as they provide flexible heating solutions; i.e. they heat up quickly and cool down quickly too. The advantages of using radiators are tremendous, as they are healthy, responsive and controllable as per the requirements of the user, which ends up saving time, owing to their heat dissipating capabilities. They are also safe to use as their surfaces remain warm, without causing any damage to things that are in contact with it or are in the close proximity. How much a new central heating system and effective radiators costs are nothing compared to how much you will save on time efficiency and medical bills if you don’t have a central heating system.
