The average cost of £87 for business travellers staying in UK hotels is £22 more expensive than booking into properties in Europe, according to the latest figures from online travel agent HRS.
London is the most expensive city in Europe with an average rate of £116 per night achieved through bookings made via HRS during Q1 2015, an increase of 15.6% year-on-year.
Taking total hotel expenses into account, HRS's data shows guests spend an average of £202 in the UK, compared with £129 in Europe.
Jon West, managing director of HRS in the UK and Ireland, said: "It's interesting to see how much more business travellers are paying for a night away in the UK compared with Europe. Our annual 2014 Price Radar study showed that room rates for a night in London had become the highest in Europe, and on average, hotel rates in the UK soared by an average of 9% last year."
He added: "Whilst Europe might look cheaper on paper, it's important to remember that other costs such as transfers and flights, as well as time spent travelling, quickly mounts up, so keeping business trips within the UK could actually be cheaper for a business in the long term."
