Social landlords need to find and fix damp and mould hazards quickly, and ventilation is usually the core of the fix. We survey homes, install continuous extract, PIV or heat recovery as needed, measure the airflow, and report per address so your asset and compliance teams have evidence of what was done.

How it works

Awaab's Law came into force for social landlords in England on 27 October 2025. It sets timescales for investigating hazards, making homes safe from significant damp and mould, and dealing with emergencies, with more hazard types added from 30 November 2026. Ventilation contractors are a common part of meeting those timescales.

We can take reactive jobs, planned programmes and voids. Each home gets a short survey, a recommended fix, installation, a flow test and a report with photographs. Tenant liaison, access letters and missed-appointment handling are agreed with you at the start.

Options we fit

Reactive damp and mould jobs

Surveys and fixes raised from tenant reports, prioritised to your timescales.

Planned programmes

Block or estate-wide upgrades to a standard specification.

Void works

Ventilation upgraded and tested before re-letting.

Data and reporting

Per-home reports, photos and airflow readings in the format your systems need.

Signs you need this

  • A rise in damp and mould reports from tenants
  • Stock with fans that have failed or been switched off
  • Retrofit insulation programmes that need ventilation alongside them
  • Voids that need ventilation fixed before re-letting
  • Evidence needed for regulators or complaints
  • Contractor capacity stretched by Awaab's Law timescales

The rules that apply

England

In England, ventilation is covered by Part F of the Building Regulations and its guidance, Approved Document F (2021 edition). Serious damp and mould is a hazard under the Housing Health and Safety Rating System, and social landlords now have fixed timescales under Awaab's Law. Awaab's Law has applied to social landlords in England since 27 October 2025, with timescales for investigating and fixing significant damp and mould.

Wales

Wales has its own Part F ventilation guidance, published by the Welsh Government, and work is checked by building control. Rented homes in Wales must be fit for human habitation under the Renting Homes (Wales) Act, and damp and mould is one of the matters considered.

Scotland

In Scotland, ventilation is covered by the Building (Scotland) Regulations and section 3 of the Technical Handbooks, and most building work needs a building warrant first. Scottish rented homes must meet the Repairing Standard (private) or the Scottish Housing Quality Standard (social), which cover damp.

Northern Ireland

In Northern Ireland, ventilation is covered by the Building Regulations (Northern Ireland) and Technical Booklet K. Landlords in Northern Ireland have repairing and fitness obligations that cover serious damp.

Questions people ask

What does Awaab's Law require social landlords to do?

Awaab's Law requires social landlords in England to investigate potential hazards within set timescales, make homes safe from significant damp and mould within 5 working days of the investigation, and deal with emergency hazards within 24 hours, with more hazards added from 30 November 2026.

Can you work to our specification and frameworks?

Yes. We can work to your specification, product lists and reporting format, and discuss framework or call-off arrangements.

How much does a social housing ventilation upgrade cost?

A typical per-home upgrade with PIV or continuous extract fans costs £650 to £1,450 excluding VAT, depending on the specification and number of wet rooms. Programme pricing depends on volume and location.

Do you handle tenant access?

We can manage appointments, access letters and reminder calls, or work with your own tenant liaison team.

Do you provide evidence for each home?

Every home gets a report with photographs, products fitted and measured airflow, in a format your teams can upload.

Can ventilation be done alongside insulation retrofit?

Yes. Retrofit under PAS 2035 needs a ventilation assessment, and we can install and test the ventilation measures that come out of it.
