As temperatures rise during the summer months, staying cool becomes a priority, especially in a heatwave. Weather forecasters from the Met Office have warned that the UK is facing soaring temperatures that are likely to be long-lasting and could reach as high as 32°C in parts of England and Wales this weekend.
In addition, with critically low reservoir levels, hose pipe bans are kicking in in parts of the UK as drought takes hold. A ban came into effect on Friday, 11th July, across much of Yorkshire, parts of North Lincolnshire and parts of Derbyshire, after the region saw one of its driest Springs on record, with other areas were hot on the heels of Yorkshire Water.
Staying safe and comfortable during a heatwave becomes essential. At Northern Energy Gas, we’re committed to supporting our LPG customers with smart, practical advice to help them stay safe, comfortable, and energy-efficient during extreme temperatures.
Read our top tips to find out what you can do to ensure your LPG system stays safe and trouble-free, while keeping you, your family, and your home cool.
Why heatwaves matter for LPG systems
Bulk LPG systems are fitted with many safety features and are designed to operate safely all year round. However, excessive heat can put additional pressure on your LPG tank and pipework. Understanding the impact of high temperatures and taking a few simple precautions can help avoid any unnecessary risks.
LPG tank safety in high temperatures
As temperatures rise, so does the pressure inside your bulk LPG tank. This is why it’s standard practice to fill LPG tanks to a maximum of 85% capacity. This leaves room for the gas to expand in hotter weather.
It’s important to keep the area around your tank clear of shrubs and debris, and keep it well ventilated, and get to know where your emergency shut-off valve is located (usually located outside the building, near where the gas supply enters the property).
In extremely hot weather, the increase in pressure inside the LPG tank may activate the pressure relief valve (PRV) – this is a safety device which usually also includes a UPSO/OPSO valve, a second-stage LPG regulator system with vital safety features for pressure control.
The PRV valve is designed to open to release extra pressure with may build up inside the tank. Keep away from the PRV at all times, and if it does vent, do not attempt to reset the valve yourself. Contact your LPG supplier’s 24-hour emergency telephone line for advice.
The OPSO valve will trip and shut off the gas supply if pressure becomes dangerously high, especially if the system is poorly ventilated. Never try to reset the OPSO valve – this must always be done by a GAS SAFE qualified engineer. Turn off the supply at your tank, switch off all appliances and contact your LPG supplier immediately.
Not forgetting your LPG pipework
LPG pipework expands in hot weather too, although in well-designed systems, expansion gaps and flexible connections allow for safe movement.
Whilst LPG pipework is built to handle outdoor conditions year-round, above-ground pipework can become extremely hot to the touch in extreme temperatures which puts the pipework under additional strain. If you smell gas or suspect a leak, turn off the supply at the tank and contact your LPG supplier immediately.
LPG bulk storage tank regulations become more important than ever during a heatwave because, whilst stored and used correctly, LPG is extremely safe, when temperatures rise, so do the risks.
Next, we’re taking a look at what you can do at home to keep cool and save water.
Manage sunlight and airflow
North-facing windows can be opened as they don’t get the sun and are more likely to get a breeze, whereas south-facing windows should be kept shut and curtains and blinds closed during daylight hours, i.e., between 9am and 9pm, to block out direct sunlight. Open windows in the evening and early morning to create a cross-breeze when the air outside is cooler.
Keep cool
Wear loose clothing. Cool yourself down by putting your hands and feet in cold water and take lukewarm showers to reduce your body temperature without the shock of a cold shower.
Whilst fans don’t lower room temperatures, placing a bowl of ice in front of a fan can circulate cooler air throughout your rooms. As the air passes over the ice, it cools down, creating a refreshing breeze.
Stay hydrated
Drink plenty of cold water throughout the day. Keep water bottles in the fridge and sip regularly. Limit alcohol, avoid caffeine, including tea and coffee, and enjoy cold treats such as ice lollies for a refreshing boost.
Reducing your water usage
We all use water every day, and can tend to take a ready supply for granted. But water supply isn’t endless, and small changes to our daily routines can make a big difference.
Spend less time in the shower. Use an egg time, or find a four-minute song with which to time your shower. Turn the tap off when brushing your teeth. When waiting for the hot tap to warm up, collect the cold water in a jug and pour into the toilet rather than flushing, or use to water plants.
Fill the kettle less and only boil the water you need. Use full loads for your washing machine or dishwasher. This will not only save water, but will also reduce your energy usage too.
Use a watering can instead of a hose or sprinkler – hosepipes or sprinklers can use as much as 1,000 litres of clean water an hour. Save even more by using the leftover water from boiling vegetables or pasta once cooled. Water plants with a watering can in the morning while the sun is up but not at its hottest, or in the evening – this makes the water less likely to evaporate.
Heat can seriously affect physical heath, especially in older people or those with underlying health conditions. It’s important to keep an eye out for signs of heat stroke or heat exhaustion. If you suspect someone may be affected, wrap them in a cold, wet sheet and seek medical advice.

Frequently Asked Questions
Is it safe to use LPG during a heatwave?
Yes. Bulk LPG tanks are designed to operate safely throughout the year, including during prolonged periods of hot weather. They include built-in safety features that automatically manage changes in pressure as temperatures rise.
Why are LPG tanks only filled to 85%?
LPG expands as temperatures rise. Leaving around 15% empty space inside your tank allows room for the gas to expand safely without creating excessive pressure.
Should I cover my LPG tank to keep it cool?
No. LPG tanks are designed to be installed outdoors and should never be covered with tarpaulins, blankets, or other materials that could restrict ventilation or interfere with safety features.
What should I do if I smell gas near my LPG tank?
Turn off the gs supply at the tank if it is safe to do so, keep away from the area, avoid naked flames or electrical switches, and contact your supplier immediately on their emergency number.
How can I prepare for future heatwaves?
Keep the area around your LPG tank clear and familiarise youself with the location of your emergency shut-off valve (ECV). Your LPG tank has a safety sticker displaying important information, including your supplier's emergency contact number. This sticker should never be removed, covered or damaged as it ensures you have the details you need in an emergency.
