Annual service, filters, heat exchanger clean and a measured airflow check for existing MVHR.
Greater London · England
Homes, rentals and business premises in Forest Hill and SE4, SE6 and SE23.
From MVHR in a new extension to a TR19 clean for a takeaway, work in Forest Hill starts the same way: a clear look at the building and a written price before anything is fitted.
In many Forest Hill 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 Forest Hill is priced from a site visit or your drawings. Kitchen extract cleaning, LEV testing and servicing visits are priced per system.
Annual service, filters, heat exchanger clean and a measured airflow check for existing MVHR.
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.

It depends on the job. As a guide, new ducted fan to outside through the loft or ceiling (insulated duct, roof or soffit outlet) is typically £525 to £900 inc VAT per fan, using London rates.
