Decentralised Extract Ventilation
What is the minimum intermittent extract fan ventilation rate in a kitchen adjacent to a hob?
Last Updated: 23 September 2025The minimum intermittent extract rate for a kitchen fan adjacent to a cooking appliance in the UK is 60 litres per second (l/s). Building Regulations Approved Document F stipulates this rate specifically for cookers and hobs to effectively remove moisture, grease, and combustion products generated during cooking.

What’s the difference between a dMEV and a dehumidifier?
Last Updated: 26 November 2025The core difference is function: a dMEV system actively extracts stale, moist, polluted air from a home and exhausts it outside, thereby providing continuous ventilation. A dehumidifier, conversely, only removes moisture from the air already present within the room and does not provide essential fresh air exchange, making it a dedicated humidity control device without...
Why is continuous extraction a proactive measure against mould?
Last Updated: 9 September 2025Continuous extraction is a proactive measure against mould because it removes moist air before condensation occurs. By maintaining steady airflow, it prevents damp from building up on cold surfaces, reducing the risk of mould growth, structural damage, and health problems in UK homes. Understanding Continuous Extraction Continuous extraction means running fans at a low, steady...
