Food Waste Disposal Units
A kitchen waste disposal unit fits beneath your sink and grinds food waste, peelings, and cooked leftovers into fine particles that flow away with the waste water. Turn on the tap, switch on the unit, and the powerful motor does the rest - no food waste caddy, no trips to the bin, no mess.
Waste disposal units are also an environmentally responsible choice, significantly reducing the amount of food waste going to landfill. When used correctly and maintained regularly, they produce far less odour than a food waste bin kept under the sink. Our range includes units from Rangemaster and InSinkErator, with models suitable for everyday domestic use through to heavier demand.

FAQs About Food Waste Disposal Units
Most food waste is suitable, including cooked and raw scraps, peelings, and small soft bones in higher-powered models. Hard bones, fibrous vegetables such as celery and artichokes, large quantities of coffee grounds, and grease or cooking oil should be avoided, as these can damage the grinding mechanism or block the drain.
Yes, fully legal. Some older guidance suggested they placed strain on sewage systems but current UK water authority guidance permits their use in domestic properties.
Yes, they are compatible with most standard 90mm waste outlets. However, while most stainless steel and composite sinks are compatible, you must also consider sink thickness. If you are fitting a disposal unit to a thick ceramic or Belfast sink, you will likely need to purchase an extended flange to ensure the fitting reaches through the sink bowl. Always check both the outlet size and your sink's thickness before purchasing.
Yes, there is an element of noise. However noise levels vary significantly by motor size. Entry-level models are noticeably louder; higher-end InSinkErator models include sound insulation and run considerably quieter.
Not necessarily. Some models connect via a standard plug socket and are straightforward to retro-fit. Others require hardwired electrical connections, in which case a qualified electrician is needed alongside the plumbing connection. Always check the installation requirements in the product specification.
