UK households urged to keep windows closed from Friday until Saturday
Hot weather is still expected in parts of the country on Friday and Saturday, as the Met Office confirmed 29C was recorded in London this week - and Brits are being urged to take action
Brits are being warned to keep their windows shut - along with their curtains and blinds - from today until at least Saturday as temperatures soar unexpectedly.
Today saw a sharp rise in the mercury, with the Met Office confirming a sizzling 29.3C at Kew Gardens, London. While the heat is set to dip slightly, parts of the UK can still anticipate balmy conditions on Friday and Saturday. Met Office Deputy Chief Meteorologist Michael Silverstone commented on Wednesday: "We are experiencing a brief very warm or even hot spell, which isn't abnormal for the time of year. However, if we reach 30C on Thursday, May 1, it will be the earliest date in May that the UK has seen 30C since our records began in 1860."
He added: "This week has already seen highs of 24.5C at St James's Park on Monday and 24.9C at Ross-on-Wye and Trawsgoed on Tuesday. Temperatures are set to climb to 29C or even 30C [on Thursday]. By Friday, the heat will start to ease, though parts of the south and south east may still reach 27C or 28C. The weekend will bring cooler conditions, with more average temperatures for all parts by Sunday."
As the UK faces a scorching May sun, our homes are heating up - challenging the high insulation designed for chilly British winters. It means British households are encouraged to introduce steps that will maintain cooler indoor environments during sunny spells.
Energy experts are dishing out advice on how to keep our homes cool without burning cash. OVO Energy advises against the urge to open windows during a heatwave, saying: "Tempting as it is to fling open the windows at the first sign of summer, it's not actually the best idea. To keep your house cool, you need to keep the hot air out."
The firm suggests keeping windows firmly shut. It added: "This means keeping windows closed during the day – particularly south-facing windows. Keep curtains, blinds and windows shut when the sun is shining directly on them, and when you're out. Try opening windows on the most shaded side of your home, to avoid sunlight and hot air getting in."
BOXT's Andy Kerr says Brits struggle with getting rid of the heat because homes here are built like toasty fortresses designed to cling onto warmth. Many believe that blasting fans or leaving windows wide open will cut through the heat – but Andy says otherwise.
He said: "Getting rid of unwanted heat in your home can be difficult in the summer months, especially when most UK properties are built to retain heat. While grabbing a fan or opening up all your windows are often mentioned as effective ways to cool your home, these methods may not result in the desired results.
"To help homeowners keep cool as the warmer months approach, we have revealed which common home cooling hacks are myths and why they don't work so you can avoid them this summer. When temperatures are particularly warm, opening up all your windows will let more hot air into your home, heating up your home and making you feel warmer.
"Instead of opening all your windows, it is much better to strategically open windows to create cross breezes throughout the day and open your windows during the night to let cooler air in."

Thousands watch summer solstice sunrise at Stonehenge - on what could become hottest day of year so far
Thousands of people gathered at Stonehenge to watch the summer solstice sunrise, marking the year's longest day - on what could become the hottest day of the year so far. Those gathering at Stonehenge had a warm start, with temperatures in Salisbury and Greater London reaching 18C by 5am, according to the Met Office. The Met Office confirmed "many places" in England and "one or two areas" in Wales, including Cardiff, entered a heatwave on Friday. The forecaster confirmed the highest overnight temperatures were recorded in Yeovilton, in Somerset, and Crosby, in Merseyside, both reaching 19.7C by 6am on Saturday, with towns in Cumbria and Lancashire recording temperatures above 19C. An amber heat-health alert is in place for all regions in England over the weekend. Solstice events at Stonehenge are some of the rare occasions when visitors are allowed to get close to the stones at the World Heritage site, which was built to align with the sun on the solstices. Solstices are believed to have been celebrated at Stonehenge for thousands of years. The summer solstice sees the sun rise behind the Heel Stone, the ancient entrance to the Stone Circle, with rays of sunlight being channelled into the centre of the monument. It takes place as one of the Earth's poles reaches its maximum tilt towards the sun as it reaches its highest position in the sky, giving the longest period of daylight for the year and signifying the end of spring. It comes as scattered thunderstorms are set to hit the UK amid continued high temperatures on Saturday, with 34C possible in some areas. The yellow weather warning for thunderstorms covers all of northern England, from Nottingham to up above Newcastle, and will come into force from 3pm and last until 4am on Sunday. The Met Office warned the most intense storms could produce "frequent lightning, large hail and gusty winds, as well as a chance of flooding. Parts of eastern England could see temperatures beat the 32.2C seen on Thursday, making it the hottest day of the year so far. There will also be very high UV and pollen levels across the country, the Met Office said.

‘Intense' thunderstorm warning issued as heatwave temperatures rise
A yellow thunderstorm warning has been issued for today as Brits swelter under the hottest day of the year so far. The warning comes into place from 3pm today, with ' the most intense storms producing lightning, large hail and gusty winds, along with some heavy downpours', the Met Office forecasts. Parts of the East and West Midlands, the North East and North West of England are all covered under the warning. Wales and Yorkshire also face intense storms. There is a 'small chance' homes and businesses could face power cuts, and communities cut off by flooding. It comes as the latest spell of hot weather is expected to peak today – with temperatures of 34°C, below the June record of 35.6°C in 1976. Wildfire warnings are also in place, along with amber health warnings in parts of the UK. London Fire Brigade Assistant Commissioner Pat Goulbourne said: 'With temperatures exceeding 30 degrees Celsius and the driest spring in over a century, the risk of fires spreading rapidly is high. 'With so many of our open spaces close to homes and livelihoods, it is vital we all play our part to reduce the chance of grass fires breaking out in the first place and to protect our communities from incidents.' Aidan McGivern, from the Met Office said: 'We keep the plume of warmth and increasingly humid air across eastern parts of the UK on Saturday night, so another uncomfortable night for sleeping in the east, a little more comfortable in the west.' By Sunday, the warmer system will move northeastwards and bring with it fresher air from the Atlantic.
