We want our brands to be the first choice for anyone looking to go out for a relaxed, casual meal or drink, whatever the occasion. We now have around 1,700 restaurants and pubs in the UK and Germany, trading under a wide range of brands and formats. On average these businesses have average net sales of almost £23,000 a week and make over £180,000 operating profit a year, some of the highest levels in the industry. Food sales have increased by almost 60% per pub over the last five years and around three-quarters of our sales are now generated from the guests who eat out in our restaurants and pubs.
Our strategy is clear. We want to ensure customers keep coming back by keeping our brands fresh and building on their reputation for quality, choice, service and value. We want to use the strength of our brands to develop more sites, trading with recognisable and popular offers. With more sites and more customers, we can make the most of our scale in purchasing, marketing and more, and achieve even better returns on investment. And we want to make sure we've got the right people in place, with the right training and motivation to ensure our customers always get excellent service.
The Company must also continue to be financially sound and we have reduced our debt significantly in recent years. Our remaining debt is guaranteed at very favourable terms against our high-quality and cash-generative restaurant and pub businesses, most of which are freehold. However, we intend to be flexible about our property ownership to ensure we make the most of opportunities as they arise.
We believe the strength of our brands, the quality of our property and the location of our restaurants and pubs, our great range of food and drink, and the friendly professionalism of our people mean that our business will thrive and successfully grow in the future.
