 The Cost of a New Boiler in 2024

Moving from the basics to specifics, buying a new boiler in 2024 might need a budget between £1,500 and £3,500. This price tag includes not just the machine but also paying for someone to put it in your house.

Different machines like combi boilers or system boilers have different prices. Some can even reach up to £15,000 based on what they do and how complex they are.

Adding other things like smart thermostats or special pumps can increase the total cost. A heating expert usually asks for £60 to £100 every hour for setting up these systems. The whole process of getting a new setup could add an extra £500 to £1,500 to your bill.

For homes with more than one bathroom, picking a system boiler within this range could offer better hot water flow and central heating benefits.

Factors Influencing the Cost of a New Boiler

  • The location where the boiler will be installed.
  • The type of boiler being considered, such as a combi, system, condensing or conventional boiler.
  • Any additional conversion costs that may apply.


Cities generally have higher installation prices compared to rural areas.
Where you live can change what you pay for your new boiler.

Different regions also mean different energy suppliers and options are available. Some places might use more liquefied petroleum gas or have better access to renewable energy sources like solar panels or ground source heat pumps.

Choosing an energy supplier that matches your needs can help control running costs, no matter where you live.

Type of boiler

The type of boiler you choose affects the cost and how your home is heated. Combi boilers are great because they heat water instantly without the need for a tank. System boilers work with a cylinder to store hot water, making them good for homes with more than one bathroom.

Conventional boilers require both a cylinder and a tank but are suitable for larger homes where lots of hot water is used at once. Biomass boilers use natural materials like wood pellets instead of gas or oil, offering an eco-friendly option.

Deciding on the right boiler also depends on your house’s size and how much hot water you use. Bigger houses with many rooms might need systems or conventional boilers, while smaller homes could be better off with combi or biomass models.

Breakdown of Costs for Different Boiler Types

Combi boiler costs

Combi boiler prices can vary. For a gas combi boiler, you might spend around £2,900 plus VAT. If you choose an electric model, the cost starts from £1,250 and can go up to £4,500.

The average price for electric types begins at £1,525.

The choice between gas and electric will greatly affect your upfront costs. Think about energy bills too. Gas boilers usually mean lower monthly costs than electric ones. Remember installation isn’t the only expense.

You may also need changes to your central heating system or extra pipework.

System boiler costs

For gas system heaters, you can expect to pay around £1,750 plus VAT. If you choose an oil system heater instead, the price jumps to about £3,925.00. System heaters work well with hot water tanks in your home, making sure you have plenty of warm water when you need it.

Switching to electric system processors costs about £1,750 plus VAT as well. These are great for houses off the natural gas grid and can help make your home more energy efficient.

Electric models heat up water quickly and are known for being eco-friendly because they don’t burn fossil fuels as gas or oil types do.

Condensing boiler costs

Fitting a new condensing boiler costs about £1,750 plus VAT. This price includes the boiler itself, installation fees, and extra charges. Extra charges might be for an extended warranty or getting rid of your old boiler.

You need to keep these in mind when planning your budget.

The total cost can vary based on several things like where you live and any special needs for installing the unit. It’s smart to get quotes from different companies so you can find the best deal.

Always make sure they include all possible costs in their estimates so there are no surprises later on.

Conventional boiler costs

Moving from the expense of condensing boilers, we next explore the cost of traditional boilers. For a smaller model, expect to pay around £1,250. 

These types are ideal for larger homes as they need both hot and cold water tanks.

Traditional boilers are wallet-friendly for spacious properties. Keep in mind that you must have room for water storage vessels. These systems require space but offer efficient heating and hot water supply across larger areas without relying on mains pressure.

Biomass boiler costs

The average installation cost is between £1,500 and £4,500, depending on the type of boiler. Various manufacturers offer different price ranges for different models and types.

Installing a biomass boiler comes with a wide range of costs based on the type and model you choose.

Need for a New Boiler

Is your current boiler costing you more in repairs? Perhaps it’s not as efficient as before or reaching its retirement age. Understand why a new boiler might be the right choice.

Increasing repair costs

Increasing repair costs can be a significant factor in the decision to install a new boiler. Older boilers may require frequent repairs, leading to higher maintenance expenditures over time.

The average labour cost for installing a new boiler is between £1,500 – £4,000 + VAT, emphasising the potential financial impact of ongoing repairs.

Moreover, newer radiators are up to 50% more efficient, reducing the need for costly maintenance and repairs associated with older systems. Power flushing the heating system and installing magnetic filtering systems can also improve heat efficiency and decrease the likelihood of expensive repairs.

Inefficiency of current boiler

The current boiler’s inefficiency can lead to higher running costs. An inefficient boiler may only achieve an energy efficiency rating of 60% or less, resulting in increased fuel consumption and higher monthly costs.

The lower efficiency could also mean that the heating system struggles to maintain a comfortable temperature, leading to potential discomfort during colder months. Upgrading to a more efficient boiler with a rating of 90% or above can notably reduce energy bills while ensuring better performance and comfort.

Age of the current boiler

The age of a boiler impacts its efficiency and reliability, with an average lifespan of 10-15 years. After this period, older boilers often experience decreased performance, leading to higher energy consumption and potential repair needs.

A well-maintained boiler may reach the upper limit of this range, but it’s crucial to consider replacing older boilers to ensure energy efficiency and reliable heating. With advancing technology in boiler systems and increasing energy-saving measures, newer models offer improved performance and lower energy consumption compared to older counterparts.

Relocation of the boiler

Moving a boiler to a new location can cost around £3,000. Signs that indicate the need for relocating the boiler include addressing physical space needs or an extension project where the current position of the boiler may not be suitable.
