Spending on eating out in the UK increased 13.5% during the summer, compared with the previous year, driven by increased consumer appetite for delivery services, particularly healthy food, according to new research from Cardlytics.

The new research, which looked at the spending behaviour of six million people between 7 July and 28 August 2016found that home delivery saw a 23% increase on the corresponding period in 2015, while quick-service restaurants saw an 18% rise.

While overall average spend per visit fell by 5.2% during the summer months, consumers ate out more frequently compared with the same period last year.

Cardlytics said this suggested consumers benefited from a general fall in retail prices and an increase in promotional activity, as revealed by the latest index from the British Retail Consortium and industry analysts Nielsen.

Home delivery was the strongest performing category, with growth across overall spend, number of orders, and average transaction value.

The research found that while casual dining and pubs still held the majority of market share, average transaction value for both categories fell by more than in any other category – 7.2% and 6.9% respectively.

According to Cardlytics, brands that thrived in the summer months included London-based sushi and bento business Wasabi, fish and chip restaurant brand Harry Ramsdenʼs and better burger brand Five Guys.

Cardlytics UK head of business development Duncan Smith said: “Our comprehensive data shows that despite the economic uncertainty, the restaurant sector had an excellent summer. Consumer appetite for spending on eating out remains healthy but brands will have to continue to work hard as competition for discretionary spend is likely to build towards the end of the year. The move towards new home delivery services is an interesting one because it has the potential to fundamentally change the relationship between restaurants and their customers. Brands will have to consider this new dynamic, particularly as they seek to build loyalty.”
