What moves the price
- Type of ventilation — a wall fan costs less than an inline fan or positive input ventilation unit
- Ducting — long duct runs through lofts or ceilings add materials and labour
- Coring walls — cutting new holes through solid brick takes specialist kit
- Controls — humidity sensors, timers and continuous-running fans cost more
- Electrics — a new switched supply for the ventilation unit may be needed
- Condensation severity — homes with serious mould may need whole-house ventilation
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 ventilation installation would have cost about £570 — an estimate from today's guide price and that index, not a recorded price. Source: ONS MM23 D7DO →

How to pay less
- Fit a ventilation fan through an outside wall where possible rather than long inline ducting
- Tackle condensation with ventilation first, which can avoid repeated mould treatment
- Have ventilation fitted during a bathroom or kitchen refit when walls are open
Before you book
- Kitchens and bathrooms need mechanical ventilation under the Building Regulations
- If you rent, damp and mould are usually the landlord's responsibility to fix
- Ask whether the ventilation unit needs servicing or filter changes
- Electrical work in bathrooms is notifiable, so use a registered electrician
Ventilation Installation cost: questions people ask
£120–£1,200 per job, about £400 typical for a PIV unit. A simple wall fan costs least; a PIV unit with ducting costs the most.
Two to four hours for an extractor fan and half a day to a day for a loft PIV unit.
A loft or wall unit that gently pushes filtered air into the home, diluting moist air and reducing condensation and mould.
Often, when condensation is the cause. Penetrating or rising damp needs the source fixed as well.
Mould treatment, redecorating, roof vents and new circuits are separate. Ask whether the unit itself is included.
