Born in York, North Yorkshire, Allan joined the youth system of hometown club York City in 2002 at the age of eight. He signed for Northern Premier League Division One South side Hucknall Town on loan in October 2011, making his only appearance as a substitute against Stamford before returning to York in November.
While still a second-year trainee, he signed a one-and-a-half-year professional contract with York on 6 December 2012, with manager Gary Mills commenting: "Tom has come on unbelievably in the last 12 months and thoroughly deserves his first professional contract". He joined Conference North side Harrogate Town on a one-month loan on 21 November 2013, having made four appearances for York up to that point in 2013-2014.
His debut came two days later in a 3–0 victory away to Workington, and made one more appearance for the club before returning to York on 20 December 2013.

He was released by York in May 2014, as the offer of a new two-year contract was withdrawn after he failed to respond to it within a one-month timeframe.
