This really does depend on how often the oven is used and what is cooked in it. An oven that is regularly used to cook fatty meats will need more regular visits than an oven that is perhaps used once a week to warm through ‘ready meals’. Many clients use our service twice a year but this is by no means ’standard’. We will be there when you need us again and we will write to you once or twice a year to remind you of the date of our last visit. Your technician will give you quality advice about repeat visits when at your premises.
