The result sees the homeworking firm surpass its £245 million projection and smash its original £200 million target to finish the year 59% ahead of where it was at the end of its 2024 year.
Average gross sales per agent also came in 3% ahead of last year at £5,588, which InteleTravel put down to holidaymakers spending more "despite a difficult economy".
Tricia Handley-Hughes, InteleTravel's UK and Ireland managing director, described the figures as an "incredible achievement", particularly when considering current economic and geopolitical tensions.
"As these relationships mature, the trust in the brand evolves, keeping everyone motivated and ahead of the game," she said. "It's a testament to our partner-advisor relationships and support."
InteleTravel initially set a £200 million sales target for 2025. However, come the agency's InteleTravel Quest conference in September, it was already on course to "smash" that projection.
"I want you to take ownership of that, because you're part of that result," said co-founder and chief executive James Ferrara, addressing the more than 450 agents at the event in Porto.
