As the colder months draw in, residential buildings across the UK face a range of seasonal risks. From icy walkways and frozen pipes to increased fire hazards and water hygiene issues, there is much to prepare for before the winter.
Preparing your block for the colder season is a proactive step towards maintaining compliance, minimising risk, and protecting residents. This guide outlines the key areas of preparation, with practical steps to ensure your building is winter-ready.
Fire Safety & Compliance Checks
Weather conditions can affect the performance of your building’s fire safety measures. Fire doors may swell or stick due to damp, or suffer from seal shrinkage, which can reduce their efficacy.
To ensure they’re in great working condition, fire doors can be inspected for closing speed, alignment, gaps, and the condition of intumescent strips.
Equally, your Fire Risk Assessment may reflect different hazards in the autumn and winter months, so keeping it up to date is key. For example: portable heaters being used in communal staff areas or holiday decorations obstructing escape routes.
Water Hygiene & Legionella Control
With residents away for the holidays and communal areas perhaps seeing less use, stagnant water becomes a risk. Legionella bacteria thrive in lukewarm, stagnant water, and winter conditions can lead to exactly that.
To mitigate legionella risk, duty holders can:
- Continue or increase flushing regimes in unoccupied flats or low-use spaces over the holiday season.
- Monitor water temperatures, especially in perimeter units more exposed to the cold.
- Check that their written scheme of control for Legionella remains active and compliant.
A professional Legionella Risk Assessment can help verify whether your existing controls are robust enough for winter and provide some reassurance if you’re at all unsure.
Slips, Trips & Falls
Cold weather increases the likelihood of injuries in outdoor communal spaces. Fallen leaves, rainwater, and frost combine to create ideal conditions for slips – especially for entrances, footpaths, ramps, and car parks.
To reduce the risks, duty holders can:
- Clear gutters, downpipes and drains, to avoid water pooling and creating icy patches
- Treat paths for moss and algae which become slippery when wet
- Prepare a gritting plan or install anti-slip mats where needed
- Check and replace outdoor lighting to ensure all access points and walkways are well lit, especially as daylight hours shorten
Internal Maintenance & Resident Comfort
Faulty heating, ventilation issues, or deteriorating insulation in communal areas can lead to cold spots, damp, and discomfort.
We would advise:
- Testing communal heating systems and thermostats, including timers.
- Confirming that extractor fans are operational to help prevent condensation build-up.
- Inspecting roof voids and loft spaces for damage to insulation, pipes or air bricks.
- Ensuring emergency lighting and smoke detectors are tested and logged.
Don’t forget internal corridors, lift lobbies, and bin stores – areas that are often missed.
Communication with Residents
Clear and early communication with leaseholders and tenants is one of the most effective ways to support winter preparedness. A seasonal safety bulletin might include:
- Information on winter maintenance checks that are planned or underway.
- Reminders not to block vents or air bricks, which are essential for ventilation and moisture control.
- Encouragement to report draughts, leaks, or faulty heaters promptly
- Fire safety advice, particularly around decorations, candles, and electric heaters.
- Emergency contacts for heating, leaks, or communal repairs.
Reassuring residents that proactive steps are being taken strengthens trust and reduces reactive callouts during peak winter periods.
