Understanding Boiler Types


Gas Boilers

Gas boilers are a popular choice for homeowners in Cardiff due to their energy efficiency and cost-effectiveness. They use natural gas to heat water, which is then distributed throughout your home. The cost of a gas boiler installation can vary based on factors such as the boiler’s size, brand, and complexity of the installation.

Oil Boilers

Oil boilers are an alternative to gas boilers and are often chosen by those without access to the gas grid. They work by burning oil to heat water, making them a reliable choice for heating in Cardiff. The cost of an oil boiler can vary depending on the size and type of boiler required.

Combi Boilers

Combi boilers, short for combination boilers, are a space-saving option that provides both heating and hot water from a single unit. They are efficient and cost-effective but may have higher upfront costs.

Factors Affecting Cardiff Boiler Costs


Boiler Size

The size of the boiler you choose significantly impacts the overall cost. A larger home may require a more powerful boiler to adequately heat the space, which can increase the cost of installation.

Boiler Efficiency

Investing in a high-efficiency boiler might have a higher initial cost but can lead to long-term savings on energy bills. These boilers are designed to maximize heat output while minimizing fuel consumption.

Installation Complexity

The complexity of the installation process also affects costs. If your home requires significant modifications or if the boiler installation involves intricate pipework, you can expect higher expenses.

Cost Breakdown


Let’s break down the costs involved in a typical Cardiff boiler installation project:

  1. Boiler Purchase: The cost of the boiler itself is a significant portion of the project expenses. It can range from £1,500 to £4,000 or more, depending on the type and brand.
  2. Installation: Boiler installation costs vary, but you should budget around £500 to £1,000 for labour and additional materials.
  3. Pipework and Accessories: If your installation requires new pipework or additional accessories like thermostats and valves, factor in an extra £200 to £500.
  4. Gas or Oil Supply: For gas boilers, ensure your home has a gas supply, and for oil boilers, consider the cost of an oil tank installation if needed.
  5. Permits and Regulations: Don’t forget to account for any necessary permits and compliance with building regulations, which may incur extra costs.
