Home ventilation, Isle of Wight
Continuous extract fans (dMEV) in the Isle of Wight
Quiet low-energy fans that run all the time and boost automatically when humidity rises, across the Isle of Wight.
- From £380 inc VAT per fan
- By arrangement
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.
If you are anywhere in the Isle of Wight, send the postcode and a few photos and we will tell you what we would recommend. Towns we cover include Cowes, Sandown, Newport and Ryde.

What the work involves
dMEV fans replace ordinary intermittent fans in bathrooms, kitchens, utility rooms and WCs. On trickle speed they are barely audible and use very little power; on boost they reach the higher continuous-extract rates in Approved Document F (in England, at least 13 litres a second for a kitchen, 8 for a utility room or bathroom and 6 for a WC). Landlords and housing associations often choose them because tenants cannot switch them off and forget them.
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.
Whole-home dMEV upgrade
Every wet room converted at once, with trickle vents checked in the habitable rooms.

Questions about continuous extract fans (dMEV) in the Isle of Wight
Which towns in the Isle of Wight do you cover?
All of the Isle of Wight, including Cowes, Sandown, Newport and Ryde. If your town is not listed, send the postcode and we will confirm.
What is the difference between dMEV and MEV?
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.
Do I still need trickle vents?
Yes. With continuous extract, Approved Document F still expects background ventilators in habitable rooms so replacement air can get in.
Are prices different in the Isle of Wight?
Our guide prices are adjusted by region. In the Isle of Wight we use South East rates, so continuous-running extract fan (dMEV) with humidity boost, flow tested is typically £380 to £650 inc VAT per fan.
