Other highlights of the report include the cost of a first-class flight which has risen by 22% a year on average since 2016.
The research shows that flying from London to New York cost £4,500 three years ago, but today the same flight sets you back £6,000 – an extra £1,500.
It also highlights the added price pressures involved with luxury goods and services. While the costs of rare materials and higher levels of service fuel higher price tags to begin with, increasing demand and limited supply are the main drivers of above-inflation price rises.
Coutts head of asset management Mohammad Kamal Syed says one way to try to beat the effects of inflation is to invest as part of a carefully thought-out financial plan.
“The fact is that holding cash in a savings account could cost you dearly,” he says. “You may see it as a safe-haven tactic, but inflation can quietly, constantly corrode the real value of your money when prices rise faster than the interest it makes.
“Investing over the long term, on the other hand, could potentially provide a greater return than a standard savings account and help preserve, or ideally increase, the value of your wealth.”
