What extractor fan installation involves
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. Wales, Scotland and Northern Ireland have their own rules, which we follow where the job is.
Ducted to outside through the loft
Insulated duct to a roof, ridge or soffit outlet so warm moist air does not condense in the loft.
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.

Rules in England
English building work follows Approved Document F (2021 edition) for ventilation rates, installation and commissioning. It sets extract rates for kitchens, bathrooms and utilities and asks for mechanical ventilation to be commissioned and recorded.

Questions about extractor fan installation in Derbyshire
Which rules apply to ventilation in Derbyshire?
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.
Should I get a fan with a humidity sensor?
A humidistat fan switches on when the air gets damp and runs until it clears, which suits family bathrooms and rentals where people forget the switch. A continuous-running fan is another good option.
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.
Which towns in Derbyshire do you cover?
All of Derbyshire, including Heanor, Derby, Chesterfield, Long Eaton and Ilkeston. If your town is not listed, send the postcode and we will confirm.
Are prices different in Derbyshire?
Our guide prices are adjusted by region. In Derbyshire we use East Midlands rates, so like-for-like extractor fan replacement (existing duct and wiring) is typically £170 to £290 inc VAT per fan.
