What is central heating installation?

Rather than simply just installing a boiler, central heating installation refers to the installation of all associated components necessary for a central heating system. You might require central heating installation if you are building a new property, undertaking a property redevelopment, or changing the type of heating system in your home from electric storage heating or another older system.

A recent full central heating installation

In the below video, you will be able to see a recent full central heating installation that we undertook in a property development in Cyncoed, Cardiff. The property which was formerly a doctors surgery was being redeveloped into a day nursery and required an upgraded heating system to meet building regulations. To this property, we installed the complete pipework, all new radiators, and an Ariston Clas ONE combi boiler.

How much does central heating installation cost?

boiler prices

The average cost of installing a full central heating system into a 3-4 bedroom house is £5,500. For a 2 bed house, the average cost of this will be £4,700

However, the cost of this depends on a number of factors. These include:

  • Where your boiler will be installed 
  • The type of boiler you require 
  • The boiler fuel type you require
  • The gas pipework needed
  • The heating controls you choose
  • Type of flue required ie vertical or horizontal
  • Condensate pump if required
  • Whether an old system economy 7 electrical has to be removed
  • Whether converting to natural gas from LPG or oil

How long will it take to install a central heating system?

On average, it will take 2 heating engineers between 2-5 days to install a full central heating system. Installation times will vary depending on the size of your property and whether or not you are currently living in the property. If you are living in the property, the heating engineers will need to work around you so the installation will take longer.

Below you will find the typical installation times for various installation scenarios:

Installation type:
Installation of a combi boiler and five radiators into a one-bedroom flat with one bathroom
Average installation time: 2 days
Installation type:
Installation of a combi boiler and eight radiators into a three-bedroom semi-detached house with one bathroom
Average installation time: 2 – 3 days
Installation type:
Installation of a combi boiler and 10 radiators into a three-bedroom three-story terrace house with two bathrooms
Average installation time: 2 – 3 days
Installation type:
Installation of a system boiler and 15 radiators into a four-bedroom detached house with two bathrooms
Average installation time: 3 – 4 days

The central heating installation process

At Boilerhut, we follow set processes to ensure that each installation is undertaken to the highest standards. The central heating installation process will usually take place in the following order:

  • Installation of the radiators in rooms around the property – The radiators will be sited first so that the engineer can see where the pipework should connect to. Once this has been done, the radiators will be fixed in place using brackets drilled into the wall
  • The pipework will be laid – At Boilerhut, we utilise copper pipes. These will be laid around your property and will be connected to the various outlets, water tanks (where relevant), radiators, and boiler that make up your central heating system. This can be a time-consuming job, especially where the flooring needs to be taken up
  • The new boiler will be installed – We will shut off the water and gas (if relevant), in order to undertake the installation of the boiler
  • Setting up the heating system – We will make sure that all of the vents on the radiators are closed and then fill the heating system with water. We will then vent the radiators to rid them of excess air. The boiler will then be switched on to warm up the water and we will use the radiator valves to balance the hot water flow around the system

Things to consider

  • Your boiler budget

The price of boilers varies widely depending on the make and model. This will have the greatest impact on your overall budget

  • The pipework required 

The layout of your home and necessary pipework will have an impact on the cost of your central heating installation(ie either copper or plastic and pipe sizes selected)

  • Where will your boiler be installed?

Typical installation locations include kitchens, utility rooms (if trying to fit the new boiler into a cabinet, dimensions are vital), airing cupboards and garages

  • The boiler fuel type

Is your property connected to the gas mains network? If no, you will have to consider an alternative option such as an oil boiler or an LPG boiler

  • The most suitable boiler type for your property

Will a combi,( storage combi boiler) a system boiler or a conventional boiler be best suited to your heating and hot water needs

  • The flooring you have in your property

To install pipework, we will need to take up the flooring in your property. Depending on the flooring type, this can have an impact on the time it takes to complete the installation. For instance, laying pipework underneath solid flooring which has already been laid is virtually impossible and is not advised. It should be noted that taking up laminate flooring can be damaging to the panels and these may not go back down in the same way.

Central heating installation FAQs

For a 3-4 bedroom house, it will cost approximately £5,500 to install central heating.

Planning permission is not usually required for central heating installation, providing the installation isn’t being undertaken in a listed building. If your property is listed and you are unsure whether you will need permission, it is worth checking with your local planning authority.
