Average cost of central heating installation

Central heating installation can be a significant investment, but it's one that can improve the comfort and value of your home. The price you'll pay depends on several factors, including the type of system you choose, the size of your property, and the complexity of the installation. To give you a clearer idea of what to expect, we've compiled a price guide based on average costs in the UK.

The cost of installing a new central heating system varies widely. For a typical three-bedroom house, you might expect to pay between £3,000 - £6,000 for a complete system installation. This includes the boiler, radiators, pipework, and labour. Upgrading an existing system or replacing components might cost less, depending on the work required. For example, replacing an old boiler with a new, more efficient model could cost between £1,500 and £3,000. Additional factors, such as the need for new radiators or extensive pipework replacement, increase the overall cost.

ComponentAverage Cost
New gas boiler£1,500–£3,000
Radiators (per unit)£40 - £100
Installation labour£500–£1,000 (varies by size of property and complexity)
Total system£3,000 - £6,000 (for a typical three-bedroom home)

Remember, these are average costs and they can vary based on your specific situation, including the type of boiler you choose, the number of radiators required, and any additional work like updating pipework or thermostat controls. It's always a good idea to get multiple quotes to ensure you're getting the best deal for your needs.

When planning for a new central heating system, it's essential to account not just for the primary components like boilers and radiators but also for additional factors that could impact the final price. These may include the complexity of installation, the need for extra pipework, controls, and even the type of fuel your system will use. Some considerations to keep in mind include:

  • Boiler type: The choice between combi, system, and conventional boilers can affect the cost, with combi boilers generally being more affordable to install.
  • System complexity: More complex systems, such as those requiring extensive pipework or adding zones, can increase the cost.
  • Property size: Larger homes require more radiators and potentially a more powerful boiler, raising the price.
  • Additional features: Upgrades like smart thermostats or advanced controls can add to the cost but offer long-term savings and convenience.

How long does central heating installation take?

The duration of central heating installation can vary significantly based on several factors, including the size of your home, the complexity of the system being installed, and whether it's a new installation or an upgrade of an existing system. Here's what you can typically expect:

  • New installations: For a completely new central heating system in a typical three-bedroom house, the process can take up to 3 to 5 days. This includes installing a new boiler, radiators throughout the house, and laying all necessary pipework.
  • Boiler replacement: If you're simply replacing an old boiler with a new one, the work can often be completed in 1 to 2 days, assuming there are no complications and the new boiler is of a similar type and size.
  • Upgrading radiators: Adding or replacing radiators can usually be done in 1 day per radiator, depending on access and any adjustments needed to pipework.
  • Full system upgrade: If you're upgrading an entire system, including the boiler, radiators, and controls, it might take up to 4 to 7 days. This is because the system might need to be redesigned to accommodate the new components.

These timelines are estimates and can vary. Factors such as; the need for additional pipework, the condition of existing installations, and the type of floors and walls (concrete floors, for example, can complicate pipework installation) can all influence the duration of the project.

How to reduce the costs of central heating installation

Reducing the costs of central heating installation requires a blend of smart planning, informed choices, and sometimes a bit of negotiation. Use these tips to help you save money without compromising on quality or efficiency.

Get multiple quotes: Don't settle for the first quote you receive. Look around and get estimates from several installers to compare prices and services. This will also give you a better bargaining position.

Choose the right boiler: Opting for the most suitable boiler, not necessarily the most expensive one, can save you money on the upfront costs as well as in the long run through efficiency savings. Combi boilers, for instance, are often cheaper to install and might be perfect for smaller homes.

Upgrade in off-peak seasons: Installers may offer discounts during quieter periods, such as late spring or early summer, when demand for heating installations is lower.

Consider government grants: Look into any available government grants or schemes that can help offset the cost of installing energy-efficient heating systems.

DIY some tasks: While the technical aspects of installation should be left to the professionals, you might be able to undertake some preparatory work yourself, such as clearing the area around the boiler or radiators.

Reuse or repair parts: If some components of your existing heating system are still in good condition, ask your installer if they can be reused. For example, some radiators might only need a good clean or minor repairs to continue being effective.

Negotiate on extras: If your quote includes additional features like smart thermostats or upgraded controls, consider whether these are essential. If not, removing them from your plan can reduce costs.

Buy materials yourself: Sometimes, purchasing the boiler or radiators yourself can be cheaper than going through the installer, who may add a markup. Just make sure to consult with them first to get the right specifications.

Remember, while it's important to keep costs down, you shouldn't compromise on the quality of your central heating system or the installation service. Opting for the cheapest quote might lead to higher maintenance or energy costs down the line.

FAQ - Frequently asked questions about central heating installation

Can I install central heating myself to save costs?

While it might be tempting to undertake the installation yourself to save money, central heating systems involve complex plumbing and gas work that require professional expertise. Incorrect installation can be unsafe and may invalidate warranties or insurance policies. Always use a certified and experienced installer.

How often should I service my central heating system?

To ensure your central heating system runs efficiently and safely, it's recommended to have it serviced annually by a qualified professional. Regular servicing can help identify issues before they become major problems, saving you money in the long run.

Can upgrading my boiler really save me money?

Yes, upgrading to a more energy-efficient boiler can lead to significant savings on your energy bills. Modern boilers are more efficient, meaning they use less gas to heat your home, which can save you money over time. The initial cost may be higher, but the long-term savings can be substantial.

Is it worth getting a smart thermostat?

Smart thermostats can offer considerable savings on your heating bills by allowing you to control your heating more efficiently. They learn your schedule and adjust heating accordingly, ensuring you're only heating your home when necessary. While there is an upfront cost, the potential savings make them worth considering.

Do I need to replace all my radiators if I get a new boiler?

Not necessarily. If your radiators are in good condition and compatible with the new boiler, you may not need to replace them. However, if they're old, inefficient or don’t work with the new boiler, upgrading them together with the new boiler can maximise efficiency and warmth.
