What the numbers mean for landlords and agents
Roughly one in seven English homes is "non‑decent", and the private rented sector carries the highest rate of any tenure (about one in five). With around 4.6 million private rentals in England, the Renters’ Rights Act 2025provides for a Decent Homes Standard and Awaab’s Law requirements in the PRS. The government’s January 2026 policy statement says the new Decent Homes Standard will apply from 2035, so these figures describe the scale of the sector rather than a PRS regime already in force. Check current regulations for Awaab’s Law timing and detailed duties.
Because a single HHSRS Category 1 hazard (excess cold, damp and mould, falls, fire) fails the standard, and BRE estimates poor housing already costs the NHS around £1.4 billion a year, accurate, timely condition recording is becoming both a legal duty and a commercial necessity.

What percentage of homes fail the Decent Homes Standard?
The English Housing Survey has reported around 14–15% of homes in England as "non-decent". The private rented sector has historically shown the highest rate — roughly one in five PRS homes — which is why the Renters’ Rights Act 2025 extends a Decent Homes Standard to the sector.
How big is the private rented sector?
Around 4.6 million households rent privately in England — about 19% of all households — according to the English Housing Survey and ONS. The government’s January 2026 policy statement says the new Decent Homes Standard will apply to private rented homes from 2035; Awaab’s Law timing and detailed requirements should be checked in current regulations.
What is a Category 1 hazard and how common is it?
A Category 1 hazard is the most serious band under the Housing Health and Safety Rating System (HHSRS). Estimates from the English Housing Survey put around 10–11% of English homes as containing one. A Category 1 hazard means a home fails the Decent Homes Standard and the local authority has a duty to act.
What does the Renters’ Rights Act 2025 change?
Part 1 tenancy reforms took effect on 1 May 2026. The Act also provides for a private-sector Decent Homes Standard and Awaab’s Law requirements. The government’s January 2026 policy statement says the new Decent Homes Standard will apply from 2035; consult current regulations for Awaab’s Law timing and detailed duties.
