Positive input ventilation (PIV)
Loft or wall units that gently push filtered air into the home to tackle condensation.
Greater London · England
Homes, rentals and business premises in Fulham and SW5, SW6 and SW10.
Our team is based in Great Barr, Birmingham, about 104 miles from Fulham. We plan each Fulham job around the survey, so you get a fixed written price and an agreed date rather than an estimate on the day.
In many Fulham homes the first step is better extraction in the kitchen and bathroom. If the windows still stream after that, a PIV unit or continuous fans usually finish the job.
Commercial work in Fulham is priced from a site visit or your drawings. Kitchen extract cleaning, LEV testing and servicing visits are priced per system.
Loft or wall units that gently push filtered air into the home to tackle condensation.
Bathroom, kitchen and utility fans sized to the Part F rates, ducted outside and tested.
We find why the house is wet and fix the ventilation, rather than painting over mould.
Tested fans and PIV for rental homes and HMOs, with records for your property file.

Guide prices using London rates. Home prices include VAT at 20%; business prices exclude VAT. A guide price is not a quote: we confirm a fixed price in writing first.
In England, ventilation in new and altered homes is covered by Approved Document F of the Building Regulations. Landlords also have duties under the Housing Health and Safety Rating System, and workplaces must be ventilated under the Workplace (Health, Safety and Welfare) Regulations 1992.
It depends on the job. As a guide, like-for-like extractor fan replacement (existing duct and wiring) is typically £210 to £355 inc VAT per fan, using London rates.
