What moves the price
- Wall or inline — a wall fan through an outside wall is quicker than an inline loft fan with ducting
- Coring the wall — drilling a new hole through solid brick takes time and specialist kit
- Duct length — long duct runs to an outside wall or roof add materials and labour
- Controls — humidity, timer and motion sensor fans cost a little more
- Wiring — an extractor fan needs a switched supply, and a bathroom fan has to suit the zone it sits in
- Replacing or new — swapping an old extractor fan is cheaper than a new installation
Electrical work prices in the UK are up 6% over five years (ONS Consumer Price Inflation, Services for maintenance and repair, to 2026 August). Five years ago a typical extractor fan installation would have cost about £220 — an estimate from today's guide price and that index, not a recorded price. Source: ONS MM23 D7DO →

How to pay less
- Replace an existing extractor fan in the same position to avoid coring a new hole
- Choose a wall fan where an outside wall is available, which is cheaper than inline ducting
- Have the fan fitted during a bathroom refit when walls and ceilings are open
Before you book
- Bathrooms and kitchens need mechanical ventilation under the Building Regulations
- Electrical work in bathrooms is notifiable under Part P, so use a registered electrician
- Choose a fan with a humidity sensor or overrun timer to clear moisture properly
- Check where the duct will vent outside, away from windows and neighbours
Extractor Fan Installation cost: questions people ask
£150–£500 per fan, about £300 typical. A wall fan through an outside wall costs least; an inline fan with long ducting costs the most.
Two to four hours for most homes, and about an hour or two for a like-for-like swap.
New or refitted bathrooms need mechanical ventilation under the Building Regulations, and a fan is the best defence against condensation and mould.
Wall fans are cheaper and simpler. Inline fans are quieter and suit rooms with no outside wall.
Making good, decorating, roof vents and new circuits are often extra. Ask whether the fan unit itself is included.
