Understanding boiler costs

The cost of a new boiler installation is an investment that depends on multiple factors. From the type of boiler and its brand to its size, efficiency, and the complexity of the installation process, each of these factors contributes to the overall cost. On average, you can anticipate spending somewhere between £1,500 and £4,500 on a new boiler installation in 2024.

There are many factors that contribute to boiler pricing, such as:

Boiler types

Boiler installation costs are dependent on the type of model. There are three main types of boilers - combi, system, and regular. Combi boiler installations are usually the least expensive, starting from around £1,500, followed by system boiler installations (£1,700 starting price), and then regular boiler installs at (£1,800 and above).

Combi boiler prices

‍Combi boilers, also referred to as combination boilers are the most popular and affordable type of boiler in the UK, providing heat for radiators and hot water on demand. They are compact, do not require a storage tank, and are suitable for small to medium-sized homes. As they are relatively easy to install, combi boiler costs are usually lower, with prices starting around £1,500 per installation.

System boiler prices

System boilers require a storage cylinder for hot water. However, they take their water supply directly from the mains, unlike regular boilers. They are suited for homes with more than one bathroom and where lots of hot water usage is needed at the same time. System boiler costs begin at approximately £1,700 for an installation.

Regular boiler prices

‍Also known as traditional, conventional, or heat-only boilers, regular boilers are ideal for homes that already have a traditional heating and hot water system linked to a separate hot water cylinder. These boilers need a cold water storage tank in the loft to feed the hot water cylinder and another tank to maintain the water level of the central heating system. Regular boiler costs typically start from around £1,800 including installation.

How much do different boiler brands cost?

The brand of the boiler significantly influences the cost. Renowned brands like Worcester Bosch or Vaillant can charge premium prices due to their reputation for quality and reliability, however, there are reliable, efficient brands such as Ideal and Navien that offer budget-friendly boiler models.

Ideal boilers

An established British brand, Ideal Boilers has been delivering reliable home heating solutions for over a century. Offering an extensive range of energy-efficient combi, system, and heat-only boilers, Ideal is popular for its cost-effectiveness and excellent warranty terms. Ideal boiler installation costs start from approximately £1,600, offering a fusion of quality and value.

Worcester Bosch boilers

As one of the most reputable brands in the UK boiler market, Worcester Bosch is known for its cutting-edge engineering and high-quality products. Their boilers, whether combi, system, or regular, have consistently received top scores for efficiency, making them a favourite among homeowners. Expect Worcester boiler installation costs to start from approximately £1,900.

Alpha boilers

Alpha Heating Innovation is another well-respected UK brand, lauded for its combination of affordability and quality. Alpha's impressive range includes highly efficient combi and system boilers, boasting innovative technology and design.

Navien boilers

Their high-efficiency boilers employ state-of-the-art technology, ensuring optimal performance, substantial energy savings, and reduced carbon emissions. Prices vary, reflecting the innovative technology and premium components used in Navien's products.

Boiler sizes and efficiency

Boiler size and efficiency play crucial roles in determining the cost of a boiler:

Size

The size of a boiler refers to its heating output, usually measured in kilowatts (kW). The boiler size required depends on the size of your home, the number of bathrooms, and the amount of hot water needed. Generally, larger homes with multiple bathrooms will require a boiler with a higher kW output, which can increase the boiler cost.

Efficiency

In 2024, energy efficiency is not just a buzzword; it's a necessity. High-efficiency boilers can save a substantial amount on your energy bills over their lifespan, often offsetting their higher initial costs. For instance, replacing an old G-rated boiler with a modern A-rated boiler can save you approximately £300 annually. Additionally, high-efficiency boilers also contribute to lowering carbon footprints, aligning with global sustainability efforts.

Modern boilers are significantly more energy efficient than older models. High-efficiency (also known as condensing) boilers can convert more than 90% of their fuel into heat, compared to around 55% for older, non-condensing models. While these boilers can be more expensive upfront, the savings on your energy bills over time can compensate for this initial cost.
