Quiet low-energy fans that run all the time and boost automatically when humidity rises, across Edinburgh.
- 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.
Across Edinburgh the job is priced the same way wherever you are: what is fitted, how long it takes and how far we travel. Towns we cover include Edinburgh.
