Pollution information for planning applications

Guidance documents and information about ventilation systems, furnace chimneys and the Low Emission Zone.

Ventilation systems

In making a planning application for a restaurant or takeaway use, details of the ventilation system are required.

This includes elevation plans to show the ducting route (which should discharge at a high level) and details of the noise and odour mitigation incorporated within the system.

The following advice note should be reviewed and a qualified ventilation engineer employed to ensure correct sizing of equipment and ducting is presented in the submitted planning application details.

The system should be designed to avoid noise and/or odour becoming a problem to neighbouring residents.

Furnace chimney height approval

Unless the height of a furnace chimney has been approved by the Council and any conditions attached to approval adhered to, it is an offence to cause or knowingly permit a furnace to be used to:

  • burn pulverised fuel
  • burn at a rate of 45.4 kg or more an hour any other solid matter or
  • burn at a rate equivalent to 366.4 kW or more any liquid or gaseous matter.

Contact us to apply for chimney height approval

When we receive your application we will give a written decision within 28 days of receipt (unless it is agreed in writing between us and the applicant that a longer period is allowed).

If for any reason we fail to deal with the application within this time period, then approval without qualification is given.

Low Emission Zone

The borough of Lewisham is part of London's Low Emission Zone, which affects older, diesel-engined lorries, buses, coaches, large vans and minibuses. Find out if your business vehicles are affected.
