Ventilation for landlords and letting agents in Surrey
Tested fans and PIV for rental homes and HMOs, with records for your property file, across Surrey.
- From £1,650 inc VAT per property
- Free survey

Between tenancies is the best time to fix ventilation in a Surrey rental, but we work around tenants too.
Our team is based in Great Barr, Birmingham, and we work throughout Surrey, from Banstead, Leatherhead, Ewell, Woking and Guildford. We survey first, free of charge for new installations on the mainland, then send a fixed written quote.

How we do it
In England, damp and mould is one of the hazards assessed under the Housing Health and Safety Rating System, and councils can take enforcement action. Awaab's Law already sets strict timescales for social landlords, and the Renters' Rights Act provides for similar duties to be extended to private renting. Wales, Scotland and Northern Ireland have their own standards, but the practical answer is the same: moisture has to be extracted.
Rental package
A PIV unit plus two humidity fans: a typical fix for a damp 2 to 3 bed rental.
HMO ventilation
Extract for every kitchen and shower room, often with continuous fans tenants cannot switch off.
Portfolio programmes
Multiple properties surveyed and upgraded to one standard, with a report per address.

Yes. Most fan and PIV jobs are done in a few hours with tenants at home, and we clear up as we go.

Every job comes with photos, product details and measured airflow, so you can show what was done and when.
