What extractor fan installation involves

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.

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.

Questions about extractor fan installation in County Down

Are prices different in County Down?

Our guide prices are adjusted by region. In County Down we use Northern Ireland rates, so like-for-like extractor fan replacement (existing duct and wiring) is typically £160 to £270 inc VAT per fan.

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.

Is the survey free in County Down?

Visits here are by arrangement. Because of the ferry or long travel involved, we quote travel separately and in writing before you commit, and we can often combine visits to keep the cost down.

Which rules apply to ventilation in County Down?

In Northern Ireland, ventilation is covered by Technical Booklet K of the Building Regulations (Northern Ireland). Workplaces must be ventilated under the Workplace (Health, Safety and Welfare) Regulations (Northern Ireland) 1993.
