CHANGES IN LABELLING DUE TO BREXIT
When the UK leaves the European Union (EU) on 1st
January 2021, the following changes will occur:
The CE mark becomes the UKCA mark
The UKCA (UK Conformity Assessed) marking is a new
UK product marking that will cover most goods that
previously required the CE mark. It will apply to all
goods that currently use CE marking.
The UKCA marking can be used from 1st January
2021 and will follow the same conformity assessment
processes as the current CE mark. CE marking can
still be used until 1st January 2022 in most cases.
However, UKCA marking will not be recognised in
the EU market, so products that currently require CE
marking will still need this in order to be sold in the EU
from 1st January 2021.
From 1st January 2022, the CE marking will
not be recognised in Great Britain for the
areas covered by the government’s guidance
– including gas appliances. However, CE
marked products will still be valid for sale in the UK as
long as they are also UKCA marked and comply with
the relevant UK rules. New rules for Northern Ireland
are to be confirmed.

From 26 September 2018, new limits for NOx emissions were introduced in addition to the eciency limits already
in force. The NOx limits have been applied to products placed on the market starting from 26 September 2018.
Products purchased before that date and already in retail outlets or distribution warehouses can continue to be
sold and installed, even though they do not comply with the new requirements.
In 2019, the UK became the first major economy in the world to pass legislation to end its contribution to global
warming by 2050. A target was set requiring the UK to bring all greenhouse gas emissions to net zero by this date.
PRODUCT LABEL
There are two different classifications for central heating
and domestic hot water; for products which can provide
both services, labels must show both the classifications.
There are dierent labels, depending on the type of
product and service guaranteed. The eciency classes A,
A+ and A++ indicate the products with higher performance.
In addition to the energy class, the labels display
information to help consumers choose the most
ecient products with less environmental impact.
ErP label changes
For products arriving or manufactured in Europe or the
UK before 1st January 2021, the current ErP label will be
accepted for use in the UK. However, after this date, a
new ErP label will need to be present; this will still comply
to the same ErP rules, but show a Union Jack in place of
the current EU flag, and all text will be written in English
only. This will be the only accepted label in the UK. For
products manufactured in Europe and destined for the
UK and Republic of Ireland, both the EU and UK labels
must be present.

SYSTEM LABEL
All units that are combined with others as
part of a system must have a secondary
label in addition to the product label and
technical documentation to show the
system performance.
The installer will be responsible in
defining the overall system performance
(through an automatic algorithm) and
must fill out the label accordingly.
