Pets at Home has upped its full-year profit guidance after announcing record third quarter results.

In the 12 weeks to 5 January, the retailer’s group revenue increased by 8.8% to £347.5 million due to every part of the business “firing on all cylinders”. Pets at Home attributed the performance to volume growth from record customer numbers.

Retail revenue climbed by 8%, or 7.6% on a like-for-like basis, after the retailer enjoyed a record trading day on 23 December with sales of over £8 million.

Meanwhile Pets at Home’s vet business grew its revenue by 18% in the period. It now has a client base of more than 1.7 million, with new registrations averaging 8,000 per week in the quarter.

The performance has led Pets at Home to increase its full-year underlying profit guidance to the upper end of the current market range of £126 million to £136 million, which is ahead of a previous forecast of £131 million.

Pets at Home has also announced that Kathryn Imrie has been appointed to the newly created role of chief consumer officer. Imrie  previously held the same role at Sky Deutschland where she helped lead the repositioning of the consumer business.
