Why UK commercial kitchens are losing thousands to blocked drains

10 April 2026

Every kitchen produces food waste. In most UK commercial kitchens, a surprising amount of it ends up going down the sink — coffee grounds, veg peelings, bits of rice, fat that congeals on the way down the waste line. It’s quiet, it’s invisible, and it’s expensive.

The hidden cost

A single emergency drain unblock averages £350 and can easily top £1,000 if a jetting unit has to be brought in out-of-hours. Multiply that across a group of sites and the number gets big, fast. That’s before you count the cost of a lost service, the hit to food hygiene ratings, or the inevitable grease trap pump-out that follows.

Where ScrapDrain fits

ScrapDrain is a high-capacity sink solids separator that drops into any standard 89mm UK commercial sink drain — no tools, no plumbers, no downtime. It captures up to 8× more than a standard strainer, so food solids stay in the basket instead of in your pipework.
