Greggs is considering introducing a loyalty card to build on its popularity following the recent pasty tax row.

The high street baker, which has about 1,600 stores, has emailed customers a survey quizzing them on whether they would be interested in a loyalty card. The survey even asked for suggestions on what the scheme could be called, including ‘Greggs Rewards’, ‘My Greggs’ and ‘Greggs Gold’.

Greggs is also considering a pre-paid card that customers could top up online or by phone.

The baker first floated the idea of a stamp-based loyalty scheme in February, following the success of a long-running coffee stamp card. But the survey suggests it is now planning to launch a comprehensive Clubcard-style scheme before the end of the year.

Such a scheme would enable Greggs to capitalise on the positive publicity it has received over the past few months after teaming up with the Cornish pasty industry to force Chancellor George Osborne into a u-turn over a plan to add 20% VAT to hot savouries.

More than 300,000 customers signed its petition objecting to the hike.
