Cosham grease trap cleaning
Need grease trap cleaning in Cosham? We survey first, send you a fixed quote and work around your opening hours, then sign off with a report and pictures.
- A small trap that fills too quickly
- A routine grease trap service
- Sinks that drain slowly
Looking after it afterwards
To keep the system working properly between visits:
- Avoid pouring boiling water down to shift grease
- Tell us when sinks start draining slowly
- Keep waste oil out of the drains
- Get food waste into the bin, not the sink
Anything we notice beyond the trap, like a slow drain downstream, is pointed out. That may need a drainage contractor to investigate.
If the kitchen has got busier, the trap fills faster. Shortening the cleaning interval now stops it overflowing.
About our grease trap cleaning in Cosham
Smells from the sink, gurgling drains or slow drainage all point to the grease trap. We find the trap, empty it and clean it, then check the water flows properly. The work covers pot wash sinks, under-sink grease traps and school and care home kitchens, and common reasons people get in touch are a bad smell from the sinks or drains and a blocked kitchen drain caused by grease.
Around a place like Cosham, deep clean work tends to mean pubs, cafés and school or care home kitchens. Smaller kitchens still collect grease behind equipment and in the drains.
Nothing is signed off by word of mouth: a written report, dated and illustrated with pictures, plus a certificate through the BESCA Vent Hygiene Elite portal when the work is a TR19® Grease clean. It shows what was done and what, if anything, couldn’t be reached.

When it’s something else
We’ll always give you a straight diagnosis, so here’s what grease trap cleaning will not do:
- Grease deep in the drains, which needs jetting by a drainage contractor
- Leaking pipework or sink wastes, which need a plumber
- A unit that cannot cope with the kitchen’s output
If in doubt, call 0345 646 2711 or use the quote form and we will say what we think.

Cosham questions
Do you clean school kitchens in Cosham in the summer holidays?
Yes. Half-terms and the summer break are the natural time for school work. The FSA’s register shows about 18 schools and colleges with food registrations within roughly a mile and a half of Cosham. Just ring 0345 646 2711 or drop us a line with your term dates and we will plan around them.
Which council inspects kitchens in Cosham?
Kitchens in Cosham are inspected by Portsmouth council’s environmental health officers. Inspection results feed into the food hygiene rating published by the Food Standards Agency.
How regularly does a grease trap need emptying?
It varies with the trap and the kitchen. Slow or smelly sinks between cleans mean it needs doing more often and we will adjust the schedule.
Can you clear our blocked drains as well?
We clean the trap, not the drain network. Where the problem is further down the drain, we will say so so you can call a drainage contractor.
Do you take the waste away?
The fat, oil, grease and solids we remove go with us. None of it goes back into the drains, of course.
Can you look after several sites?
Yes. You deal with one contact for every site across London and the South East, and visits can be set on a regular cycle.
Can you come out in an emergency?
Yes. For anything urgent, such as a fan failure or damage after a fire, ring the 24/7 line and we’ll talk you through the next steps.
Do you cover Cosham?
Yes. Cosham is part of the area we cover, within the South East and London area we cover.
Multi-site and managed buildings
Facilities teams in offices, schools and healthcare sites book us too across Portsmouth. Larger estates can be phased building by building around the people who use them.
The Fire Safety Order 2005 puts the duty to manage fire risk on the responsible person, and that can be the employer, the owner, a landlord, a facilities manager or a managing agent. Where responsibility is shared, records matter even more.
Why deal with it now?
Grease that gets past the trap doesn’t disappear. It adds to blockages further down the drains and sewer. A well-maintained trap keeps it where it can be removed. A visit arranged in advance is far less disruptive than a callout on a busy day.
Working hours, access and the scale of the site all affect the cost. We take each of them into account and give you a fixed price before we start.

- Trading since 2009
- Out-of-hours work and a 24/7 emergency line

How the job changes from site to site
Restaurant and takeaway kitchens
Busy kitchens with lots of washing-up fill traps fast. A shorter cleaning interval normally suits them.
School, care home and staff kitchens
Kitchens with fixed mealtimes build up grease more predictably. Planned cleaning fits their routine.
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. After that, the work takes a short visit for a small trap and longer for an inline unit or interceptor. Tell us when your site near Cosham is quiet and the visit will be booked for then.
- First, we find the trap and look at its connections.
- Sinks feeding the trap are taken out of use.
- We empty out the fat, oil, grease and solids.
- The chambers and baffles are cleaned.
- The trap is refitted, tested with water and the waste taken away.
Preparing for the visit
- Make sure someone can let us in and lock up afterwards
- Move anything stored near the system
- Agree a time when the area can be out of use
Ask for a quote
Quoting starts with a diagnosis, from your photos and details or, where that is not enough, a survey on site. Then we send a fixed price, before any work starts.

What else we do in Cosham
When to call us in Cosham
Food scraps go down the sink with the washing-up water. It settles in the trap as solids and fill it from below.
Any of these means the system needs a check-up:
- Gurgling drains in the kitchen
- A bad smell from the sinks or drains
- An overdue grease trap
- Washing-up water that won’t drain away
If you run a church or community hall kitchen, near Church of St Philip or elsewhere in Cosham, a deep clean and an emptied grease trap before a busy season of events are worth booking.
