If you’re considering installing a new boiler, you’re probably wondering about the cost. A combi boiler installation is a popular choice for homeowners looking to upgrade their heating systems. But how much does a combi boiler installation cost? In this article, we’ll look at the costs of a combi boiler installation.

What is a Combi Boiler?

A combi boiler is a type of boiler that combines heating and hot water in one unit. This means you don’t need a separate hot water tank or cylinder, which can save space in your home. Combi boilers are also known as combination boilers or combi boilers.

Benefits of a Combi Boiler

There are several benefits to installing a combi boiler in your home. Here are some of the most important ones:

  • Space-saving: Combining heating and hot water in one unit means you don’t need a separate hot water tank or cylinder, which saves space in your home.
  • Energy-efficient: Combi boilers are generally more energy-efficient than traditional boilers because they don’t heat up and store hot water when unnecessary.
  • Cost-effective: Installing a combi boiler can be cost-effective in the long run because you don’t need to pay for a separate hot water tank or cylinder and can save money on energy bills.
  • Fast heating: With a combi boiler, you can get hot water almost instantly because the unit heats the water as needed.

Factors Affecting the Cost of Combi Boiler Installation

The cost of a combi boiler installation can vary depending on several factors, including:

  • The size of your home: The larger your home, the more powerful the combi boiler you’ll need, which can increase the cost.
  • The type of combi boiler: There are several types of combi boilers available, including gas, oil, and electric. Gas boilers are the most popular because they’re more energy-efficient and cost-effective than other types.
  • The complexity of the installation: If your installation requires additional work, such as moving pipes or upgrading your gas supply, this can increase the cost.
  • The installer you choose: Different installers charge different rates, so shopping around is important to find the best deal.

Average Cost of Combi Boiler Installation

The cost of a combi boiler installation can vary widely depending on the abovementioned factors. However, on average, you can expect to pay between £1,500 and £3,000 for a new combi boiler installation.

Is it Worth the Cost?

The cost of a combi boiler installation may seem high, but it’s important to consider the long-term benefits. Installing a combi boiler can save you money on your energy bills, and it can also increase the value of your home. Additionally, if your old boiler is inefficient, upgrading to a new combi boiler can save you significant money on your energy bills each year.
