What does a bathroom extractor fan cost in Larne?
As a guide, budget £220 to £550 including VAT for a bathroom extractor fan in Larne; your written quote will pin it down.

Working in Larne
As well as Larne itself (BT40), we survey in Carrickfergus, Newtownabbey and Bangor.
Larne gets the same process as anywhere else: a free survey at your home and a written, itemised quote. If your Larne bathroom has black mould on the ceiling or silicone, the fan and its duct are the first things we check. We check the duct route at Larne surveys, because a short, straight run to outside matters more than the fan's headline figure.
Most of County Antrim is supplied with soft water. Even so, condensation is the bigger problem in any bathroom, and a properly sized extractor is what deals with it. Hardness varies street by street, so check the figure for your postcode with your water supplier.
What the job includes
- A backdraught shutter and external grille, so cold air does not blow back in
- A fan chosen to meet the bathroom extract rate: 15 l/s intermittent or 8 l/s continuous
- Run-on timer, humidistat or light-linked switching set up to suit how the room is used
- Core-drilling through the wall, or ducting through the loft to a roof or soffit vent
Decisions to make first
Noise
Compare the stated noise level in decibels. Inline fans and low-speed continuous fans are much quieter in the room than budget axial fans.
Replacement air
A fan needs air to replace what it removes, so leave a gap of around 10 mm under the door or fit a door grille. A sealed room starves the fan.
Rules that apply in Northern Ireland
In Northern Ireland, ventilation is covered by Technical Booklet K, and building control is involved where a new bathroom is formed. There is no Part P, but the fan should be wired, tested and certified to BS 7671.
