Mobile medium combustion plant which are boilers consultation
Overview
We are consulting on proposals to introduce a new standard rules environmental permit (SR2026 No.1) for mobile medium combustion plant (MCP) that are boilers in England.
This consultation is part of ongoing work to implement the Medium Combustion Plant Directive (MCPD), which aims to reduce emissions of air pollutants such as nitrogen oxides (NOx), sulphur dioxide (SO₂) and dust from combustion plant.
Mobile MCP boilers (for example, those hired and deployed temporarily at different sites) are regulated under the Environmental Permitting Regulations. We are proposing a simpler, standardised permitting approach for these activities.
The consultation sets out proposals for:
- a new standard rules permit for mobile boilers
- a generic risk assessment for this activity
- how mobile boilers will be regulated and deployed
- how deployments will be assessed and managed
- proposed application and annual charge
The aim is to provide a clear, consistent and proportionate regulatory approach that protects the environment while enabling industry to operate efficiently.
We are seeking views from operators, businesses, regulators, environmental groups and the public on whether the proposed standard rules and approach adequately manage environmental risks and are practical to implement.
Your feedback will help us refine the proposals before finalising the approach.
