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.

Like-for-like replacement

A new fan on the existing duct and wiring, often with an overrun timer or humidity sensor.

New fan through an outside wall

Core drilled, sleeved, wired from a fused spur and sealed outside.

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.

Questions about extractor fan installation in Clwyd

Is the survey free in Clwyd?

For new installations on the UK mainland, yes. The survey is free and the quote that follows is fixed and in writing. Servicing, testing and repair visits are charged, and we confirm the cost before booking.

How much does it cost to fit an extractor fan?

Replacing a fan on an existing duct usually costs £175 to £295 including VAT. A new fan through an outside wall is typically £345 to £545, and a fan ducted to outside through the loft £445 to £745.

Can an extractor fan vent into the loft?

No. A fan should discharge to outside, because warm, moist air dumped in the loft condenses on the cold roof timbers and causes mould and rot there instead.

Which rules apply to ventilation in Clwyd?

In Wales, the Welsh Government's own Approved Document F (2022 edition) applies to ventilation in homes, with a new edition taking effect on 4 March 2027. Rented homes must be fit for human habitation under the Renting Homes (Wales) Act 2016, and workplaces must be ventilated under the Workplace (Health, Safety and Welfare) Regulations 1992.
