Continuous extract fans (dMEV) in Warwickshire
Quiet low-energy fans that run all the time and boost automatically when humidity rises, across Warwickshire.
- From £345 inc VAT per fan
- Free survey
A dMEV (decentralised mechanical extract ventilation) fan is a low-energy extract fan that runs continuously at a quiet trickle speed and boosts automatically when it senses humidity or a light switch. Because it never fully switches off, moisture is removed steadily instead of building up between showers.
Our team is based in Great Barr, Birmingham, and we work throughout Warwickshire, from Kenilworth, Hartshill, Nuneaton, Rugby and Royal Leamington Spa. We survey first, free of charge for new installations on the mainland, then send a fixed written quote.

How we do it
Landlords and housing associations often choose them because tenants cannot switch them off and forget them. Under Approved Document F, continuous mechanical extract systems need commissioning: the airflow on both trickle and boost is measured and recorded. We do that as part of the job, so you have a record for building control, a landlord file or a future buyer.
Commissioned and recorded
Trickle and boost rates measured and written on a commissioning sheet.
Bathroom and en-suite
Through-wall or ceiling fans with humidity-controlled boost.
Kitchen
Higher-rated continuous fans where a ducted hood is not practical.
