The Landlord Briefing: Heat, Safety, and Shifting Markets

Compiled by Regulus from the week's coverage · Editor: Paul McGough · 28 August 2026

This week's stories cluster around two themes: property safety obligations — particularly overheating and fire risk — and structural shifts in the rental market as social landlords continue to retreat from private lettings. Planning reform also surfaces, with new mayoral powers raising questions about delivery timescales that could affect housing supply down the line.

Repairs, Safety & Your Legal Exposure

London Assembly members have warned that extreme heat inside homes is posing a health risk to more than one million children in the capital, with three-quarters of social homes considered at high risk of overheating. While the report focuses on social housing, the underlying issue — poorly ventilated or insulated properties getting dangerously hot in summer — applies across all tenures. Private landlords should consider whether their properties have adequate ventilation and shading, particularly if they house families with young children. Inside Housing

Fire chiefs are calling for a long-term national strategy and sustained funding to tackle wildfires, warning that major incidents are increasingly spreading to urban areas and putting homes at risk. The National Fire Chiefs Council has highlighted that fire and rescue services need investment to keep pace with the growing danger. If your rental property is near open land or green-belt areas, it is worth reviewing whether your buildings insurance covers wildfire damage and whether any garden or boundary maintenance could reduce risk.

An inquest into the death of five-year-old Aalim Ahmed, who fell from the 15th floor of a Newham Council tower block, heard from the council's housing chief that the family experienced an "unacceptable delay" in repair response times. While this case involves council-managed temporary accommodation, it is a stark reminder that slow responses to repair requests carry serious consequences — legal, moral, and reputational. Self-managing landlords should keep a clear, timestamped log of every repair report and their response to it. Inside Housing

The Scottish Public Services Ombudsman has ordered Edinburgh City Council to apologise after it let a property with mould to a visually impaired tenant with additional health difficulties, and then repeatedly dismissed the tenant's concerns. Although this involves a council landlord in Scotland, the pattern — letting a substandard property and failing to act on complaints — is exactly the kind of conduct that ombudsman schemes and courts scrutinise across all landlords in the UK.

Market Shifts: Social Landlords Leaving Private Renting

Notting Hill Genesis has agreed a £750m deal with US investor Kennedy Wilson to sell its 2,079-home private rental business — the second London social landlord in two months to exit the private rented sector. The trend signals that some large institutional landlords are reassessing the economics of private renting, which may gradually reduce supply in already tight urban markets. Self-managing landlords in London should be aware that reduced competition from institutional players does not automatically mean higher rents — it can also mean fewer professional management benchmarks and more regulatory scrutiny on those who remain. Inside Housing

The Greater London Authority has confirmed that more than 60% of the first-round funding from London's Social and Affordable Homes Programme — part of a broader £6bn initial allocation — will go directly to councils for development. Greater council-led housebuilding could eventually ease pressure on the private rental market in London, though the deputy mayor's note that allocations are expected "in coming months" suggests supply benefits are some way off.

Planning & Housing Policy

The government's updated National Planning Policy Framework now includes a presumption in favour of residential development around well-connected railway stations. Commentators from the University of Warwick welcome the direction but argue the government should be more targeted about where it encourages growth. For landlords considering longer-term investment decisions, areas near major stations may see increased development activity — and potentially more rental supply — over the coming years.

Prime Minister Andy Burnham's proposals to grant regional mayors new call-in powers over planning decisions have been broadly welcomed by the property industry, though experts warn the change could also introduce further delay and complexity into the planning process. For landlords hoping that planning reform will unlock more housing supply — and moderate purchase prices — the cautionary note on delivery timescales is worth bearing in mind. Property Week

What to Do About It

• Check your property for overheating risk. Review ventilation, window coverings, and any previous tenant complaints about summer heat — particularly if you let to families with children. Document what you have in place.
• Audit your repair response process. Make sure every repair report from a tenant is logged with a date and time, and that you have a clear record of the action taken and when. Slow or undocumented responses are a significant liability.
• Review your insurance cover. If your property is near open land, confirm with your insurer whether wildfire damage is covered. Check that your buildings policy reflects the current rebuild value.
• Monitor your local market. Institutional landlords exiting private renting and new planning presumptions near transport hubs may both affect supply and demand in your area over the next one to two years — factor this into any decisions about buying, selling, or refinancing.
