The show, which chronicles the life of Queen Elizabeth II from the 1940s to modern times, features several royal residences, with Buckingham Palace costing the most in energy bills. The 775 room palace in Westminster, London, racks up an estimated £1,078,470 ($1,423,974) per year.
Buckingham Palace could save £299,487 each year by switching from a standard variable tariff to the most competitive fixed rate energy deal currently on the market, according to Energy Helpline.
The Queen’s weekend retreat, Windsor Castle comes in second place, with the 100 room residence is the world’s oldest inhabited castle and costs £630,410 per year in energy bills.
Princess Diana’s family estate Althorp House is the third most expensive, with an annual bill of up to £130,250.
The Queen’s country home, Sandringham House in Norfolk racks up bills of £103,817 per year, while her Scottish residence Balmoral Castle costs up to £101,527 in gas and electricity bills.
Anmer Hall in Norfolk, the summer home of Prince William and Kate Middleton, sees annual energy bills of up to £58,573 while Princess Anne’s home, Gatcombe Park in Gloucestershire costs an estimated £52,716.
Kensington Palace, former home of Prince Charles and Princess Diana and now Prince William and Kate’s London home, requires an estimated £39,049 a year to run.
The Royal Household has introduced a decade-long energy management strategy, intended to improve its energy efficiency by 40%. The plan managed to reduce the cost heating and lighting in royal residences by 24% last year.
Tom Lyon, director of energy at energyhelpline.com, said: “It’s fair to say that we all love watching The Crown and getting a look inside these grand homes and, considering the size and age of these impressive buildings, it’s perhaps little wonder that their energy bills will be equally grand.
“For example, some of Buckingham Palace’s radiators are over sixty years old, and the electrical cabling and heating date from the 1950s. But with measures like installing LED lighting which uses up to 86% less electricity across the estate, it’s incredible to see the environmental and cost-savings being made.”
