ErP and Eco Labelling

The Energy-related Products Directive was introduced by the EU to phase out poorly performing products across a range of product groups to reduce carbon emissions across Europe. These include tyres, bulbs and shower heads, and since September 2015, it has also applied to residential and commercial heating products.

What is ErP?

ErP is made up of two separate directives.


EcoDesign ensures that products meet the performance and emissions standards at the point of manufacture. Any product that does not meet these requirements will not get a CE mark, and can't be legally sold in the EU. This applies to heating products with an output equal to or less than 400kW and tanks with a storage volume equal to or less than 2,000 litres.


Energy Labelling works in conjunction with EcoDesign, it requires all energy-related products to clearly display their efficiency grade, ranging from A+++ to G. Energy labels help customers identify and choose products which save energy.


Installers are required to provide an overall energy efficiency label for newly installed package of products. For this they have to calculate the efficiency figure based on certain components of the system - boiler, controls, solar thermal etc - which they write on a package label when they have completed the installation.

ErP Label Explained

What does ErP mean for installers?

ErP covers all heating and hot water products, but when it comes to boilers, the scope of ErP is limited to domestic and commercial products with an output lower than 400kW. Boilers that do not meet the requirements of ErP can't be legally installed and anyone found working with non-compliant products can be subject to fines or legal action.


As part of the Energy Labelling Directive, all heating and hot water products will be issued with an efficiency rating which must be visible on the product at the point of sale.


As well as the label on the product, and energy label is also required for the installed system, depending on the components used. It is the job of the installer to calculate the efficiency figure for the whole heating system. For example, if you are installing a boiler, hot water cylinder and controls, you would need to complete a fiche to calculate an efficiency figure for the entire system.
