Rising temperatures and recurring UK heatwaves are putting certain people at risk, particularly the elderly, those with health conditions, and those living in poorly ventilated buildings. Corridors, lobbies, stairwells, and shared outdoor areas can become hazardous in extreme heat if the right measures aren’t in place.
Heatwave planning tends to get less attention than cold weather protocols in UK property management, partly because extreme heat has historically felt like an occasional inconvenience rather than a recurring risk. But this is changing. With hotter summers becoming more frequent, communal area safety during periods of high temperature deserves the same structured approach as any other seasonal risk.
Ventilation and air circulation
Internal corridors and stairwells in older buildings in particular can trap heat at levels that are uncomfortable at best and dangerous for vulnerable residents at worst.
Where mechanical ventilation systems are in place, these should be inspected and tested before summer. Filters block up over time and reduce airflow significantly; a system that appears to be running may not be moving air effectively. If air handling units or fans serve communal areas, their servicing should sit on the planned maintenance calendar.
In buildings without mechanical systems, the approach is more manual but no less important. Identifying which windows, vents, and doors can be opened to create cross-ventilation through communal areas, and making sure these are accessible and functioning, is a straightforward measure that can make a big difference. It’s important to make sure you’re not propping open fire doors, however.
Temperature monitoring in shared spaces
Most property managers track temperature in plant rooms and server rooms as standard. Fewer extend that monitoring to communal areas, and during a heatwave that gap matters.
Deploying thermometers or simple data loggers in key communal spaces allows managing agents and facilities teams to identify where temperatures are exceeding safe thresholds. Once you have that information, you can prioritise interventions, whether that’s directing portable cooling units to specific areas, adjusting cleaning and maintenance schedules to cooler parts of the day, or flagging concerns to residents and building owners.
This doesn’t require significant investment. Basic temperature monitoring is inexpensive, and the data it produces is far more useful than relying on reported complaints, which tend to arrive after the problem has become serious.
Communal outdoor areas
Hard landscaping absorbs and retains heat through the day, which means paved courtyards, car parks and roof terraces can remain warm well into the evening.
Shade is the most effective intervention, and it’s worth assessing communal outdoor spaces in advance of summer to identify where it’s lacking. Retractable awnings, shade sails, or strategically placed planting can reduce surface temperatures and make outdoor areas usable for longer.
Water access matters too. A single outdoor tap or drinking water point in a communal garden or courtyard is a small provision that can reduce risk for residents spending time outside.
Cleaning and hygiene in high temperatures
Heat accelerates bacterial growth and speeds up the deterioration of waste. Communal bin stores and waste areas that are manageable under normal conditions can become a health concern during a heatwave if collection schedules or cleaning frequency haven’t been adjusted.
The practical response is to increase the cleaning frequency of bin areas and any communal spaces that see high footfall, and to make sure waste isn’t being left to accumulate between collections. Surfaces in heavily used communal areas, like door handles, lift buttons and entrance seating, also warrant closer attention during warmer periods when hygiene risks are elevated.
Electrical and mechanical equipment
Extreme heat puts additional strain on electrical and mechanical systems. Communal area lighting, lift motors, access control systems, and CCTV equipment all generate heat during operation, and in an already hot environment, the risk of overheating and failure increases.
Lift breakdowns during a heatwave are a particular concern in buildings with elderly or mobility-impaired residents. If lift maintenance is due, bringing it forward ahead of a forecast hot period is worth considering. More broadly, any mechanical equipment in communal areas that is already running at reduced capacity or showing signs of wear should be prioritised before summer temperatures peak.
Having a plan before the temperature rises
Reactive responses to heatwaves tend to be more costly and less effective than preparation carried out in advance. Ordering portable cooling units during a heatwave, for example, often means competing with every other property manager in the country for limited stock. Planning ahead produces better outcomes and makes the response far less stressful to manage.
A basic heatwave plan for communal areas should cover ventilation checks, cleaning schedule adjustments, any equipment that needs servicing, outdoor area provisions, and a communicable plan for residents. Reviewing and updating it annually, in the spring, means it reflects the current state of the building and can be acted on quickly.
At Dependable, our hard and soft FM services are designed to keep communal areas safe, functional, and well-maintained throughout the year. We can support you with planned maintenance programmes that anticipate seasonal risks. If you’d like to talk through your building’s summer readiness or review your current communal area maintenance provision, get in touch with the team.
