The pressure on social housing
Social housing in Wales is under more pressure than ever
Void properties sit empty for weeks while costs accumulate. Damp and mould complaints return faster than they can be resolved. Repair backlogs grow, tenants escalate to the Ombudsman, and the regulatory framework is about to get significantly tighter.
Every day a property sits empty costs lost rent, council tax, and vandalism risk. Sector-wide, voids cost an estimated £1.6bn per year.
Complaints to the Housing Ombudsman have surged. 72% stem from poor practice such as missing records, weak diagnostics, delays and poor QA.
Average repair cost per void property across approximately 300,000 voids sector-wide in 2023/24.
Social landlords spent a record £9bn on repairs and maintenance in 2023-24. The reactive maintenance model is unsustainable.
Regulation
The regulatory landscape is tightening
Under the Renting Homes (Wales) Act 2016, every dwelling must be fit for human habitation across 29 prescribed hazards. Where a dwelling is unfit, rent becomes non-payable for every day of non-compliance. Fines reach £30,000 per breach, and courts have awarded tenants 100% of rent in damages.
From 1 April 2026: new WHQS hazard rule
Imminent-harm hazards must be investigated within 24 hours and remedied within a further 24 hours. Significant risks must be investigated within 10 working days and remedied within 5.
Quarterly compliance reporting
Mandatory reporting to Welsh Government begins June 2026.
