Review of the interaction between the Market Access Principles and England’s Air Quality (Domestic Solid Fuels Standards) Regulations 2020
The Office for the Internal Market (OIM) has accepted its first joint referral from the UK and devolved administrations, to review how the Market Access Principles (MAPs) affect the UK internal market for certain products under Defra's 'Ready to Burn' scheme.
Case information
The OIM has accepted a joint referral from the Department for the Environment, Food and Rural Affairs (Defra), the Scottish Government, the Welsh Government and the Northern Ireland Department for Agriculture, Environment and Rural Affairs (DAERA) for a review of the impact of the Market Access Principles (MAPs) on the UK internal market with respect to certain products that fall within Defra’s ‘Ready-to-burn’ certification scheme. The review will speak to manufacturers, distributors and retailers and consider cross-border sales of certified and uncertified manufactured solid fuels and house coal, the role of the MAPs, and the impact on market participants.
The scope of the review does not include heating oil and is separate to other CMA work relating to heating oil. We will publish our non-binding advice to the referring governments.
