- From £330 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.
Dumfries and Galloway has every kind of building, from old terraces to new estates and business parks, and every job is designed around the building in front of us, not a standard kit.

Questions about continuous extract fans (dMEV) in Dumfries and Galloway
Is the survey free in Dumfries and Galloway?
For new installations on the UK mainland, yes. The survey is free and the quote that follows is fixed and in writing. Servicing, testing and repair visits are charged, and we confirm the cost before booking.
Are continuous fans noisy?
A correctly sized dMEV fan is very quiet on trickle; most people only notice it on boost. Noise usually means the wrong fan or a poor duct.

dMEV uses one small fan in each wet room. MEV uses one central fan, usually in the loft, ducted to all the wet rooms. Both run continuously.
