Working with landlords, housing associations and councils
Extract Energy works with private landlords, housing associations, local authorities and managing agents across Hampshire and the South Coast on damp and mould remediation, cavity wall extraction and re-insulation, loft insulation, solar PV, battery storage and EV charging. We started out fixing the problems caused by poorly fitted cavity wall insulation, so we understand what portfolio clients need: a defensible process, photographic evidence, and tenants treated properly.
Awaab's Law and damp and mould duties
Awaab's Law has applied to social landlords in England since 27 October 2025. For damp and mould that presents a significant risk of harm, a landlord must investigate within 10 working days of becoming aware, give the tenant a written summary within 3 working days of the investigation concluding, and start safety work within 5 working days of the investigation concluding. Emergency hazards must be made safe within 24 hours. From 2026 and 2027 the rules widen to other hazards, such as excess cold, fire and electrical risks, and then to the rest of the housing health and safety rating system.
It does not yet apply to private landlords. The Renters' Rights Act 2025 gives the government the power to extend it, but that needs separate regulations and no start date has been set (position as at October 2026). Private landlords are still bound by existing law to keep a home free of serious damp and mould, and councils can already enforce it.
The root cause in older stock
A lot of recurring damp and mould in 1960s to 1990s stock is not a lifestyle problem and will not be solved by another dehumidifier. In many cases it is wet or slumped cavity wall insulation bridging the cavity. Until that fill comes out, the mould will come back, and so will the complaint.
We provide:
- Borescope cavity inspections with a written summary and photographs, to support your investigation.
- Extraction of failed fill, making good, vent clearance and a full photo pack.
- Re-insulation with non-absorbent bonded bead where the wall is suitable, with a 25-year IAA guarantee.
- Loft insulation and ventilation upgrades (eaves trays, lap vents) where roof-space condensation is the cause.
- Plain-English findings you can share with tenants.
Void and tenanted-property process
We work in both. For tenanted properties, we agree access windows and keep the inside of the home as undisturbed as possible; cavity work is done almost entirely from outside.
Every job carries:
Risk assessments and method statements
Site-specific, compiled and authorised by our Managing Director.
Trained operatives
Required to hold current CSCS, working at height, manual handling, asbestos awareness and gas awareness training. Anyone out of date is stood down.
Photographic evidence pack
Pre-works and post-works photos of every elevation, the empty cavity, debris removed, colour-matched pointing, cavity brushes, vents, and all gas appliances and flues.
Completed Gas form and Post Extraction form
Uploaded to our job management system before sign-off.
Waste disposal
Removed and disposed of under Environment Agency registered upper tier waste carrier and dealer CBDU532168, with transfer notes on request.
Full insurance
Certificates on request.
Portfolio extraction and re-insulation
Where a street or estate was filled under the same scheme in the same year, the same failure tends to show up in house after house. We survey in batches, report by property, and programme extraction street by street with a single point of contact. Our capacity is up to 10 installs and 20 surveys a week.
EPC improvements and MEES
Private rented homes in England must currently meet a minimum EPC rating of E under the Minimum Energy Efficiency Standards, and the government has consulted on raising that. Cavity wall and loft insulation are the two cheapest routes to a better rating in most pre-1990 stock, and solar PV adds further points. We can survey a portfolio and show you which measures move each property.
EV chargers for rental properties
The OZEV residential landlord grant gives 75% off the cost of installing a chargepoint, up to £500 per socket and up to 200 sockets a year, for private landlords, social housing providers and property management companies. We survey and install across multiple addresses, and we will confirm at the quote stage whether the grant can be claimed on your job.
EV charger installationWarm Homes: Local Grant for landlords
Private landlords can access fully funded insulation and solar for a first eligible property under the Warm Homes: Local Grant, with a 50% contribution on further properties. The tenant must meet the eligibility rules and the property must be EPC D to G. Social housing is largely excluded, apart from a small amount of infill. The scheme currently has a waiting list in our area and does not pay to remove failed insulation. Our guide has the detail.

AccreditationsEvidence you will receive
Every extraction job produces a photographic evidence pack covering all elevations before and after, the empty cavity, the debris removed and the make good. Our case studies page shows how we write jobs up as we add them.
