Combi Boiler Efficiency Ratings – Frequently Asked Questions
How are Combi Boilers Tested for Efficiency?
Combi boilers are tested for efficiency by independent third-party organizations, such as the European Heating Industry (EHI) and the UK’s Building Research Establishment (BRE). These organizations use standardised testing methods to measure the efficiency of the boilers and to assign them an energy rating.
The testing process involves measuring the amount of heat that is delivered to the home for every unit of fuel that is consumed. This is known as the boiler’s Seasonal Efficiency of Domestic Boilers in the UK (SEDBUK) rating. The higher the SEDBUK rating, the more efficient the boiler is.
What is Tested and Why?
During the testing process, several factors are taken into account to determine a combi boiler’s efficiency rating. These factors can include:
- Heat Output: The heat output of a combi boiler is the amount of heat that it can produce, and this is usually measured in kilowatts (kW). The heat output required for a home will depend on its size and the level of insulation.
- Fuel Consumption: The amount of fuel that a combi boiler consumes is also measured during the testing process. This is used to calculate the boiler’s efficiency rating.
- Heat Exchanger: The heat exchanger is a critical component of a combi boiler, as it transfers heat from the combustion process to the water. The efficiency of the heat exchanger can have a significant impact on the overall efficiency of the boiler.
- Boiler Controls: The controls on a combi boiler can also have an impact on its efficiency. Modern boilers typically have advanced controls that allow homeowners to optimise the performance of the boiler and reduce energy consumption.
How to Easily Understand the Energy Efficient Combi Boilers Jargon
The energy rating of a combi boiler is displayed on a label that is affixed to the boiler. The label will include the SEDBUK rating, which ranges from A to G, with A being the most efficient and G being the least efficient.
To make it easy to understand, the label also includes an energy efficiency percentage. This percentage represents the amount of energy that is converted into usable heat by the boiler. The higher the percentage, the more efficient the boiler is.
In addition to the SEDBUK rating and energy efficiency percentage, the label may also include other information, such as the boiler’s heat output, hot water flow rate, and noise level.

When choosing a combi boiler, it’s important to consider both the SEDBUK rating and the energy efficiency percentage. The SEDBUK rating is a good indicator of how efficient the boiler is, but it doesn’t give a clear idea of how much energy will be saved in real-world use. The energy efficiency percentage, on the other hand, tells you exactly how much of the fuel consumed by the boiler will be converted into usable heat.
For example, a boiler with an SEDBUK rating of A may have an energy efficiency percentage of 90%, while a boiler with an SEDBUK rating of B may have an energy efficiency percentage of 85%. While the A-rated boiler has a higher SEDBUK rating, the B-rated boiler may be a better choice in terms of energy efficiency.
It’s also worth noting that the SEDBUK rating is based on ideal conditions, and the actual efficiency of a combi boiler can vary depending on a range of factors, such as the weather, the level of insulation in the home, and how the boiler is used. However, by choosing a boiler with a high SEDBUK rating and energy efficiency percentage, homeowners can be sure that they are making an informed choice and that they are choosing a boiler that is designed to be as efficient as possible.
Conclusion
Combi boilers are an energy-efficient and cost-effective choice for homeowners looking to reduce their energy bills. The most economical combi boilers in 2023 have been determined based on verified statistics and data from reliable sources, including surveys by Which? and Consumer Reports. These boilers offer high efficiency, reliable performance, and deliver hot water on demand, making them ideal for a range of homes.
Combination boilers (known as combi boilers more commanly) are tested for efficiency using standardized testing methods, and the energy rating of a combi boiler is displayed on a label that includes the SEDBUK rating, energy efficiency percentage, and other information. By understanding the energy rating of a combi boiler and choosing a boiler with a high SEDBUK rating and energy efficiency percentage, homeowners can reduce their energy bills and minimize their environmental impact.
When choosing a combi boiler, it’s important to consider factors such as heating output, hot water flow rate, and energy efficiency.
