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.

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.

Rules in Wales

In Wales, ventilation follows the Welsh Approved Document F rather than the English version, with building control checking notifiable work. We design to the Welsh rates and commission mechanical systems so the results can be recorded.

Questions about extractor fan installation in Gwent

Which towns in Gwent do you cover?

All of Gwent, including Cwmbran, Pontypool, Ebbw Vale, Caerphilly and Risca. If your town is not listed, send the postcode and we will confirm.

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.

Are prices different in Gwent?

Our guide prices are adjusted by region. In Gwent we use Wales rates, so like-for-like extractor fan replacement (existing duct and wiring) is typically £165 to £280 inc VAT per fan.

Is the survey free in Gwent?

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.
