How we do it
Many existing fans were never doing their job: undersized, ducted into the loft space, fitted with a flex duct crushed in the joists, or switched off by occupants because they were noisy. The rate a fan delivers through a real duct run is often far lower than the number on the box, which is why we size to the room and test the result. For England, Approved Document F gives minimum intermittent extract rates: 15 litres a second for a bathroom, 30 for a kitchen with a cooker hood (60 without one), 30 for a utility room and 6 for a WC.
Inline fans
A quiet fan in the loft serving one or two ceiling grilles in a shower room or en-suite.
Kitchen extract and cooker hoods
A wall or window fan, or a cooker hood ducted outside rather than recirculating.
Like-for-like replacement
A new fan on the existing duct and wiring, often with an overrun timer or humidity sensor.

Questions about extractor fan installation in Somerset
Which rules apply to ventilation in Somerset?
In England, ventilation in new and altered homes is covered by Approved Document F of the Building Regulations. Landlords also have duties under the Housing Health and Safety Rating System, and workplaces must be ventilated under the Workplace (Health, Safety and Welfare) Regulations 1992.
Do you need building regulations for a new extractor fan?
Fitting or replacing an extractor fan has to meet the ventilation and electrical rules, and certain electrical work is notifiable. We do the work to the current standards. Electrical work that is notifiable is certified by a registered electrician, and you get a copy of the certificate and our airflow readings.
How long does fitting a fan take?
A straight replacement takes an hour or two. A new fan with a core-drilled hole or a duct through the loft usually takes half a day.
Which towns in Somerset do you cover?
All of Somerset, including Bath, Weston-super-Mare, Taunton, Yeovil and Bridgwater. If your town is not listed, send the postcode and we will confirm.
Are prices different in Somerset?
Our guide prices are adjusted by region. In Somerset we use South West rates, so like-for-like extractor fan replacement (existing duct and wiring) is typically £180 to £305 inc VAT per fan.
We can usually fit a replacement fan in Somerset in a single short visit.
