You’ll know how much foodstuff costs – but do you know how much profit your equipment can make you?

Check our profitability guidelines and you’ll see that your customers could pay off the costs of our ovens in as little as 7 days – and that’s a conservative estimate!

We have oven capacities ranging from 24 to 120 potatoes an hour. Depending on your type of trade and the number of hours you serve hot food we have an oven to suit. Call us for details of your nearest King Edward stockist.

These profit calculations are based on adding a potato oven to an existing café set-up, where overheads (staff, rent, utilities) are already covered. The figures reflect the incremental food and energy costs only.
