King Charles has turned down the thermostat in Buckingham Palace in an energy cutting measure that has reportedly left staff shivering.
The new monarch, who is well known for his interest in the environment and green issues, has dropped the temperature in the Palace with people noting it is a lot colder in the Palace swimming pool, claimed a source.
It has already been revealed that the new monarch has been looking to hire a live-in chef who will be whipping up vegan meals.
Charles follows a vegan diet one day a week where he avoids eating meat, fish and dairy products for environmental reasons.
And he has also been keen to reduce the royal household’s energy use which has been a priority of his in recent years.
So far he has already installed solar panels at Clarence House, his London residence, and his country residence Highgrove, in Gloucestershire.
At Highgrove waste water is used in the gardens for the plants and flowers.
Now he has also been quick to try and cut the energy consumption at Buckingham Palace.
"A few people using the pool have noticed that the temperature of the water has dropped, and it is quite a bit cooler than it used to be. They have been told the King has had the heating turned down,” a source told The Times.
The swimming pool in Buckingham Palace is a surprise to many but is where Princes William and Harry both learnt to swim and and since then the Waleses’ own children.
The pool was commissioned by King George Vl in 1938 as he wanted to ensure privacy for his daughters Elizabeth and Margaret who had been having lessons at the Bath Club.
Another energy saving habit that Charles is well known for is turning off the lights - and it is something that his children have inherited.
The Duke of Sussex talked about it in a documentary on his father several years ago - and Prince William also admitted he was always quick to turn the lights off in rooms when they are not being used.
Speaking about their dad in the documentary Prince, Son and Heir: Charles at 70, Harry said: "He's a stickler for turning lights off.
"And that's now something that I'm obsessed with as well, which is insane because actually, my wife goes 'Well, why turn the lights off? You know it's dark'.
"I go 'we only need one light, we don't need like six', and all of a sudden, it becomes a habit and those small habit changes he's making, every single person can do. And I think that's one of the key lessons certainly that I felt that he taught us."
William agreed with his brother, adding: "I know I've got serious OCD on light switches now which is terrible."
