Everything you need to know about Energy Labelling

The Energy-related Products Directive (ErP) requires all boilers up to 70kW and water heaters and storage tanks up to 500l to be supplied with an energy efficiency label. We discuss what this means for you below.

What are energy efficiency labels?

The Energy-related Products Directive is designed to improve the efficiency of products that use energy. The energy efficiency label, (sometimes known as an ErP label), ensures that end users are aware of the efficiency levels of their products and can make educated choices.

What does the energy label look like?

Eligible products must be supplied with an energy label that gives the product a rating between A++ and G for boilers and A+ to F for water heaters. Most people will already be familiar with these, as they are supplied with many household goods such as washing machines and fridge freezers. The labels have the familiar colour scheme with A++-rated products being dark green and G/F rated products being dark red. The label will also feature the sound levels of the product rated in Decibels (dB).

Who is responsible for providing the energy label?

There are two types of ErP labels; a product label and a system label. Manufacturers will be responsible for providing a label for each product they sell which falls under the ErP Directive. This means that you will receive a label from us when purchasing a Purewell VariHeat or Stratton mk2 boiler that is 70kW or below. 

A system label must be provided by the installer of a complete heating system, for example when combining a heating appliance such as a boiler or water heater with a controls system. The system label is calculated using the different efficiency levels of each of the components of the system and is provided to the end user.
