Following the legislation update to the Energy related Products (ErP) directive on 26th September 2015, here’s a quick recap on what you need to know.

What is ErP?

The ErP directive from the European Union is designed to help the EU achieve its 20-20-20 target. That means accomplishing the below by 2020:

  • A 20% (or higher) reduction in COÐ greenhouse emissions compared to 1990 levels
  • A 20% increase in energy efficiency across the EU
  • Increasing the EU’s energy consumption from renewable sources to 20%.

This update makes it compulsory for all space and water heaters to meet minimum energy efficiency requirements, which is to be demonstrated by energy efficiency labels being used on all domestic and commercial heating products in the same way as many white goods and tyres.

The ErP Directive comprises of two sections:

  • Ecodesign – this sets the minimum requirements for energy performance and environment levels for energy related products. All products must meet the minimum requirements for energy performance to legally be sold and used in the EU
  • Energy labelling – this section requires space and water heaters to be labelled with their energy classification. This is applicable for every product with an output of less than 70kW.

What does that mean for me?

It is the responsibility of the installer to deliver accurate labelling for each complete energy system that’s installed. This means:

  • Completing a document called a ‘fiche’ – it is a supporting document to the energy label.

There is no standard format for a fiche but it must provide certain information relating to the performance and efficiency of the products installed. All suppliers are required to provide a fiche at the point of sale – usually in or with the product brochure or any other literature in the box, and installers are required to provide a fiche to the consumer when they complete the installation.

Baxi provides a really useful guide on this – visit and search ‘Understanding the fiche’.

Feeling within the industry

A study carried out for HPM Magazine just before the legislation came into action revealed that UK plumbers were positive about the changes. 67% of surveyed plumbers were reported to welcome the changes. We’d love to hear your thoughts on this.

Has this legislation change made it easier for you to choose the most efficient products? Do you feel like this change will help reduce carbon emissions and energy costs? Get in touch at
