The boss of Games Workshop has said the fantasy model retailer is not “taking anything for granted” after booming overseas and online sales helped it post a massive surge in revenues and a near-trebling in profits.

Revenues at the company, best known for its Warhammer games series, soared 54pc to a record £109m in the six months to November 26. That was partly thanks to stellar mail order sales, including those through its website, which almost doubled to £21.3m.

Chief executive Kevin Rountree said the “cracking results” showed “our business and our Warhammer hobby are in great shape”.

Pre-tax profits jumped from £13.8m to £38.8m and Games Workshop paid shareholder dividends of 61p in the period, more than twice last year’s 25p.

The news caps off a remarkable year for the once-troubled company. Its share price has surged 270pc since the start of 2017.

Mr Rountree said: “We're proud of the improving trends, but we are not taking anything for granted, our feet remain firmly on the ground as we stride into the year ahead.”

The Nottingham-based company, which was founded in 1975 and floated in 1994, sells figurines that customers build, paint and then use to battle each other in tabletop games.
