Grease trap cleaning for kitchens and businesses in Lower Holloway
A neglected grease trap stops doing its job. Further down the pipe, the grease cools and hardens, leading to slow drains, blockages and smells. Regular cleaning keeps it working. Common call-outs are for a kitchen drain that smells and gurgling from the sink waste, on inline grease traps, school and care home kitchens and kitchen waste pipes.
Fat, oil and grease poured down drains helps form fatbergs, and London’s sewers have made the news for them more than once. A grease trap that’s emptied and cleaned regularly keeps fat out of the drains.

Why act early in Lower Holloway
Grease that leaves the kitchen ends up somewhere. It adds to blockages further down the drains and sewer. A well-maintained trap keeps it where it can be removed. Choosing the date yourself beats having a fault choose it for you.
Leaving it longer rarely makes the work cheaper. Build-up, wear and faults tend to get worse, not better, and a neglected system can mean more work. If you’re unsure, phone us on 0345 646 2711 or use the quote form for straight advice and a fixed quote.

The process
When we arrive, we check the system against the survey or the photos you sent. If anything is different, we talk it through with the person on site before carrying on. From there, it takes anything from under an hour to a few hours, depending on the trap. In a London area like Lower Holloway, parking, loading and building access are planned before the day of the work.
- We agree a time when the sinks aren’t needed.
- The trap is opened up and checked.
- We remove the grease layer and settled solids.
- The inside, baffles and outlet are cleaned.
- The trap is closed, tested and the next clean discussed.
Getting ready for the visit
- Plan for cooking equipment or plant to be off before we arrive
- Mention any parking or loading restrictions
- Tell us the best time to work, such as after service or at a weekend

Common questions in Lower Holloway
Who would carry out a food hygiene inspection at a kitchen in Lower Holloway?
Food hygiene inspections in Lower Holloway are carried out by Islington council. An officer may look behind equipment and at drains, so it pays to have the deep clean booked before those areas build up.
Can parking be tricky for a job in Lower Holloway?
Tell us where a van can stop near your site in Lower Holloway, and about any building rules on loading. Working overnight, as we often do in London, typically makes it simpler.
Will cleaning the grease trap fix a blocked drain?
It depends where the blockage is. If the trap is full, cleaning it often helps, but blockages further along need a drainage contractor.
Why does a grease trap need regular cleaning?
Grease and food waste build up until the trap stops working. Slow drains, bad smells and blockages follow.
Do you have a 24/7 line?
Yes, day and night, every day of the year. Office hours are Monday to Friday, 8am to 6pm, and the emergency line covers the rest.
What types of premises do you cover?
Any site with a kitchen or a ventilation system to look after, from a small pub to a hospital. Hotels, schools, care homes, offices, shops and leisure sites are all part of our work.
What’s the right interval for grease trap cleaning?
That depends on the trap and the kitchen. A small trap fills more quickly than a large one, and busy kitchens fill them faster still. We will suggest an interval after the first clean.
