Good to hear your managing the change and staying open. My understanding is yes you will be able to make your own food inline with current food safety standards however contact or refer to your local council food safety guidelines that should be updated now to reflect Covid19. Your registered pie supplier should be able to deliver and again they will be clear on the contactless process for deliveries. If they are not able due to their own business challenges… I am sure there will be pie suppliers lining up to service you. Maybe even opportunity to support one of your local cafes who will be finding trade tough as they can only do takeaway food and coffee due to the level 3 conditions (through phone/online orders, delivery, pick-up and drive-through) they maybe keen to make and deliver to you. Best of luck!
