Hoseasons managing director Simon Altham said: “This is fantastic news for the business and the wider domestic tourism market.
“It’s been a very interesting few months for the British economy, but we know that people continue to prioritise their holidays, and with the convenience, flexibility and range of breaks on offer staying in the UK clearly remains first choice for many families, couples and groups of friends.
“The most exciting part of the data is the continued growth we have seen over the last six years.
“People often suggest that domestic holidays perform well if the sun is shining or there’s a specific reason not to travel overseas.
“The reality is that during this period we’ve had a variety of weather conditions, variable exchange rates and host of external influences on consumer short-term buying patterns, yet we’ve seen continual growth in the market.
“This all clearly points to the fact that domestic vacations are here to stay and play a very important part in how UK consumers choose to spend their holiday time.”
