Landlords face £7,000 fines as councils crack down on overheating homes
Veröffentlicht: 07.07.2026 um 10:59 Uhr, Redaktion boerse-global.de
Local authorities in England have started using new enforcement powers to tackle dangerously hot rental properties, with landlords now facing fines of up to £7,000 per hazard. The measures, available to councils since June 2026, classify excessive heat as a serious health risk under the Housing Health and Safety Rating System (HHSRS).
While English law does not set a maximum legal indoor temperature, the key test for enforcement is whether heat levels pose a credible threat to tenant health. Landlords are required to keep ventilation systems working properly — including ensuring windows can open and mechanical fans remain operational.

How the Renters' Rights Act changes the game
The tougher enforcement follows wider regulatory reforms introduced by the Renters' Rights Act in May 2026. The abolition of Section 21 "no-fault" evictions has shifted the balance of power, making tenants more willing to report hazards like overheating without the fear of being evicted in retaliation.
The Act has also shaken up the wider rental market. Rent inflation in England jumped to 6.5% in June 2026, and a new Landlord Ombudsman scheme is set to handle disputes directly between tenants and property owners, with the power to award compensation of up to £25,000.
Updated guidance on assessing heat risks
In response to changing climate data, the Chartered Institution of Building Services Engineers (CIBSE) has updated its TM59 guidance on overheating risk assessments. The revised standards now require all new homes and major refurbishments to be tested against future weather files representing the climate of the 2050s. The guidance prioritises passive design and includes new modelling rules for ceiling fans and bedroom cooling.
Industry body Propertymark has urged letting agents to treat overheating as a critical property risk. Current data suggests roughly one-fifth of homes in England already overheat during summer — a figure that could rise to one-third in the coming decades. Agents have been advised to log repairs carefully, identify vulnerable tenants, and consult contractors on improvements such as external shading, which experts say can reduce indoor temperatures by more than 6°C.
Councils step up local action
Local enforcement is intensifying alongside national changes. Brighton & Hove City Council has announced plans to expand its selective licensing scheme to the Regency and Central Hove wards from October 2026. Following a 2024 pilot programme, the move could see more than 7,200 properties requiring licences to meet safety and quality standards.
Similar protections are emerging internationally. In Ontario, Canada, amendments to the Residential Tenancies Act that took effect on July 1, 2026 now give tenants the right to install air conditioning units — even if lease clauses previously banned them — provided they give written notice and meet safety requirements. Penalties for non-compliance in Ontario have doubled to $100,000 for individuals.
As housing regulations tighten, many landlords are realising they lack the safety documentation needed to prove compliance.

Heatwave puts pressure on housing stock
The urgency of these measures is underlined by a severe July heatwave, with temperatures reaching 34°C. Amber heat-health alerts have been issued for the Midlands, eastern England and southern England for the period between July 8 and July 12, 2026.
Historical government data shows the scale of the problem: nearly 19% of bedrooms in England overheated during the summer of 2018. While the government aims to extend the Decent Homes Standard to all rented properties by 2035, the current combination of extreme heat and serious damp issues — present in roughly 10% of private rented homes — is driving immediate enforcement through on-the-spot fines.
