Higher levels of inbound business from long-haul destinations also contributed to growth levels.

Top performing trips include a three-day Leeds Castle, White Cliffs and Flavours of Kent tour, an Oxford and Cotswolds day tour and whisky-themed tours around Scotland.

Company founder and CEO Robin Worsnop said: “Our revenue overall is up 20% on the same period last year, which is good growth.
“We’ve increased our capacity and marketing to attract more customers from our long-haul markets and this is reaping rewards. Our authentic small group experiences are proving popular with our target markets.
“Visitors from further afield are much more likely to stay in the UK for a longer period, which means they want to explore.
“Our small-group tours of between one and 17 days offer a really immersive experience with expert guides. We’re also very excited about the launch of new tours from Manchester and Aberdeen in May this year.”
