Unblock kitchen sinks and waste pipes clogged with grease, food debris and limescale.
Free, no-obligation — we'll call you back fast.
Kitchen drain blockages are one of the most common drain calls we receive across London. Cooking fat, grease, food debris, and soap residue accumulate on the walls of kitchen drain pipes over time, gradually narrowing the bore until a complete blockage occurs. Furthermore, London's hard water supply means limescale builds up alongside grease deposits, creating a tough composite layer that ordinary plungers and supermarket drain unblockers simply cannot shift. We clear kitchen drain blockages using high-pressure jetting and specialist grease-cutting nozzles that scour the pipe walls back to bare clay or cast iron. In addition to fast clearance, we also explain what caused the blockage so it does not recur. Therefore, the engineer will inspect any visible run with a CCTV camera if the kitchen has blocked more than once in the last twelve months, and recommend a grease management routine matched to your usage. As a result, our domestic customers typically see year-on-year reductions in repeat call-outs, while restaurants and cafés benefit from documented maintenance records that satisfy environmental health inspections. That said, where a kitchen drain has reached complete blockage with standing water and overflow risk, our priority is always to clear the line first and discuss prevention afterwards.
Assess the extent of the blockage — is it in the trap, the waste pipe, or further in the drain run?
Clear trap-level blockages by rodding or chemical softening
For pipe-level blockages, apply high-pressure jetting with a grease-cutting nozzle
Test the full drain run is clear and flowing properly
Advise on grease management to prevent recurrence
Kitchen drain clearing in London typically costs £80-£150 for a standard residential kitchen sink blockage. Commercial kitchen drain jetting is priced individually based on the length of the run.
We don't recommend chemical drain cleaners for regular use, particularly in older London properties with clay or cast iron pipes. Caustic chemicals can damage older pipework. They may clear grease temporarily but don't prevent it reforming. High-pressure jetting is far more effective and safer for your pipework.
London restaurant and commercial kitchen drains should be jetted every 3-6 months as a minimum, depending on kitchen volume. Regular grease trap maintenance and documented drain cleaning records are increasingly required for environmental health compliance.
