Yes, you can opt-out of the food waste service if you don't want the caddies. The food waste collection is part of a new legal requirement, but residents can choose not to participate in the service.
Keep in mind that you will still need to manage your food waste properly until the collection starts, which is scheduled for the week commencing 6th April 2026. If you change your mind in the future, you can enroll at that time. If you're considering this, it might be worth discussing with neighbors about their plans for food waste management.
