England's private rented sector is bracing for a major regulatory shake-up, with revised enforcement standards under the Housing Health and Safety Rating System (HHSRS) exposing landlords to billions in potential civil penalties. Industry data suggests the sector faces a total exposure of approximately £3.5 billion in property hazard fines following the updated standards that took effect on June 23, 2026.

The Scale of the Problem

An estimated 504,808 dwellings across England contain Category 1 hazards — the most serious classification under the HHSRS. Landlords found in breach face initial civil penalties of up to £7,000, while repeated violations can trigger fines as high as £40,000.

The most common issues identified in the national housing stock include falls on stairs, accounting for 244,032 recorded hazards. Excess cold affects 130,748 properties, while dampness and mould growth are present in 64,422 dwellings.

Councils Ramp Up Licensing Schemes

Local authorities are responding to high hazard rates by proposing or expanding licensing schemes to drive compliance. In Norwich, council officials estimate that 2,286 rental homes — 11% of the local private rental market — contain serious hazards. The picture is worse for Houses in Multiple Occupation (HMOs), where one-fifth of properties are believed to have serious safety issues.

Since 2020, Norwich City Council has handled more than 670 complaints, prompting consideration of a city-wide licensing programme similar to those already operating in Great Yarmouth and Bristol.

Preston City Council has launched a consultation on a selective licensing scheme covering the City Centre, St Matthew's, and Plungington. The consultation, which runs until October 11, 2026, proposes a five-year licence fee of £1,050. Landlords would be required to conduct inspections every six months and respond to maintenance issues within 21 days. Local data shows that 16% of private rentals in these areas currently have Category 1 hazards.

The legal standing of such schemes was recently reinforced after the High Court dismissed a second judicial review against Thurrock Council's licensing programme. The ruling allows the council to continue requiring landlords across 17 wards to obtain licences, with the claimant ordered to pay £7,500 in costs.

Awaab's Law Expands

The regulatory landscape is set to tighten further with the second phase of Awaab's Law, effective November 30, 2026. The law will extend its scope to cover seven additional hazards, including electrical safety, structural collapse, and hygiene. This follows the first phase, which took effect on October 27, 2025, establishing fixed timeframes for social landlords to address reported hazards.

The government is also advancing the Renters' Rights Act to tackle discrimination in the market. The act makes it illegal for landlords to refuse tenants because they receive benefits or have children, with fines of up to £7,000 for non-compliance. The legislation also plans to abolish Section 21 evictions and establish a dedicated Private Rented Sector Ombudsman.

HMRC Cracks Down on Tax Errors

Beyond physical property standards, landlords face increased scrutiny over financial reporting. For the 2025-26 period, HM Revenue and Customs (HMRC) recovered £104.3 million from 11,511 landlords for tax errors — the highest recovery level in seven years.

New powers introduced in the Finance Bill 2027, effective April 2027, will allow HMRC to issue Customer Correction Notices for unintentional errors. Authorities have indicated that failure to comply with these notices may result in errors being treated as deliberate, potentially leading to more severe penalties.
