Keeping cool and safe during hot weather

With the record-breaking hot weather of the past few days, we've re-published some tips to help you stay cool in the heat.

Close curtains and blinds

During the hottest parts of the day, close your curtains or blinds to block out direct sunlight and help keep your home that little bit cooler.

Stay hydrated

Drink plenty of water throughout the day, even if you don't feel thirsty. Dehydration can occur quickly in hot weather. Keep a water bottle handy and encourage everyone in your household to stay hydrated.

Check on vulnerable neighbours

Keep an eye on elderly neighbours, young children, or individuals with health conditions who may be more susceptible to heat-related illnesses. If you feel able, you can offer assistance if needed and help make sure they are staying cool and hydrated.

Be mindful of food safety

During hot weather, perishable foods can spoil more quickly. Store and handle food properly to prevent bacterial growth. Keep refrigerators and freezers at appropriate temperatures and discard any items that may have spoiled.

Be aware of heat-related illnesses

Learn the signs and symptoms of heat exhaustion and heatstroke. If you or someone else experiences dizziness, fatigue, rapid heartbeat, nausea, or confusion, seek medical help immediately.

Dress for the weather

Wear loose, lightweight, and breathable clothing made from natural fabrics like cotton or linen. Light colours reflect sunlight and heat instead of absorbing it.

Seek out cool spaces

If you're out and about, look for public places that offer air conditioning, such as shopping centres, libraries, or community hubs. Spend time in these places during the hottest hours to give your body a break from the heat.

Protect yourself from the sun

Apply sunscreen with a high SPF to exposed skin and wear a wide-brimmed hat and sunglasses to shield yourself from harmful UV rays. If you can, try to avoid going outside without proper sun protection, especially when the sun is strongest between 11am - 3pm.

Limit strenuous activities

Avoid engaging in vigorous physical activities during the hottest parts of the day, typically from mid-morning to late afternoon. If you do want to exercise, try to do it early in the morning or later in the evening when it's cooler.

Keep your home cool

Consider investing in a desktop or standing fan to keep the air circulating. Depending on the size, fans typically cost between £15-£40 and can be charged with either a plug or by USB.

Use air conditioning

If you have access to an air conditioning unit, set it to a comfortable temperature and make sure all windows and doors are closed while it's running. It's better to turn off the air conditioning when you're not at home, as it will waste energy and increase your bills.

Hot weather fire safety advice

With the summer months approaching, it's important to be aware of the increased fire risks that come with hot weather. High temperatures, dry conditions, and even small actions like a dropped cigarette or an unattended BBQ can lead to serious consequences in and around your home.

You can read the London Fire Brigade’s Extreme Weather Fire Safety Guide (PDF, 547kb)  for clear, practical advice on how to stay safe during periods of extreme heat.

Quick tips to stay safe in hot weather

• Never leave BBQs unattended, and keep them well away from buildings or balconies.
• Avoid smoking on balconies — even a small spark can cause a fire.
• Keep communal areas clear of anything that could catch fire. That includes e-bikes and e-scooters.
• Stay hydrated and check in on neighbours, especially older or vulnerable residents.

If you see something that doesn’t look safe in your building or communal areas, please report it to our Building Safety Team right away.
