Grease trap cleaning in Portsmouth, done properly
Think of the grease trap as a filter for the kitchen’s drains. Kept clean, it does its job quietly, but neglected, it causes blockages and smells. Routine cleaning keeps it in good working order. If you’re dealing with a grease trap that hasn’t been emptied in a long time and a kitchen drain that smells, we can put it right.
Big kitchens in Portsmouth cannot close for a day, so we work overnight or section by section.
We’re CHAS and SafeContractor accredited, we hold ISO 9001 and we’re fully insured. On top of that, we are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we have been trading since 2009.

Grease trap cleaning around Portsmouth
Food Standards Agency records list about 8 food manufacturers and packers within 1.5 miles or so of the middle of Portsmouth. For food producers, the grease trap schedule should follow the volume going through it. Food hygiene inspections in Portsmouth are the job of Portsmouth council’s environmental health team. They look at the cleanliness of the whole kitchen: walls, floors, ceilings and equipment. A cleaning log that includes deep cleans and grease trap visits shows the work is planned.
School kitchens, at schools like Manor Infant School for example, normally have their deep cleans and grease trap work done while the canteen is closed. Healthcare kitchens, like those at hospitals such as Royal Portsmouth Hospital (about 0.7 miles south-west), cook for long hours, so deep cleans and grease trap work are planned around patients’ meals.

Other services in Portsmouth
In-house cleaning or a specialist?
Staff cleaning does not replace a specialist visit; it supports it. Regular in-house cleaning slows the build-up, but hidden parts of the system still need specialist attention.
Your own staff can handle the daily basics: wiping canopies, washing grease filters and recording it in a log. Inside the ducts, risers and fan is specialist work, which is where we come in.
Common questions in Portsmouth
Which environmental health team covers Portsmouth?
Kitchens in Portsmouth are inspected by Portsmouth council’s environmental health officers. Photos from a deep clean are a simple record of what was done and when.
Can you come to Portsmouth after we close?
Yes, we can come after you close and finish before you open. The site is handed back ready to open. Your opening times are the first thing we ask for.
Do you work in Portsmouth?
Yes. Our technicians work in Portsmouth, within the South East and London area we cover.
Does the report say when we need you again?
Yes. We put a recommended next date on the report. For kitchen extracts, BESA’s minimum intervals run from every 3 months for heavy use to every 12 months for light use, and fire dampers need testing at least once a year.
Do you take the waste away?
We remove all the waste we take out. None of it goes back into the drains, of course.
Do you have a 24/7 line?
Yes, 24/7. Office hours are Monday to Friday, 8am to 6pm, with the emergency line covering every other hour.
Do we lose a day’s trading?
Not usually. We need the work area to ourselves while we’re on site, so the visit goes in a quiet slot.
What is TR19?
It’s the industry benchmark for cleaning ventilation and kitchen extract systems, written by BESA. It sets out inspection, cleaning and record keeping and expects a risk-based approach.
Do you need grease trap cleaning in Portsmouth?
Waste cooking oil poured down the sink fills a grease trap far faster than washing-up. Even small amounts add up.
Keep an eye out for these warning signs:
- Grease setting in the kitchen pipework
- A slow-draining kitchen sink
- A kitchen drain that smells
- A full, neglected grease trap
Where a church or community hall near St Wilfrid, or anywhere in Portsmouth, has a kitchen used by volunteers, a periodic deep clean keeps it ready for the next event.

When it’s something else
Not every problem is solved by grease trap cleaning, and we’d rather say so up front. It does not solve:
- Leaking pipework or sink wastes, which need a plumber
- A grease trap that is too small for the kitchen
- Sewer problems outside the premises
If you are not sure, just ring 0345 646 2711, or email photos and we will give you a straight answer before you book.
What the work covers
- Kitchen waste pipes
- Inline grease traps
- School and care home kitchens
- Under-sink grease traps
- Pot wash sinks
- Restaurants and takeaways
Why deal with it now?
Wherever the kitchen is in Portsmouth, backed-up drains stop it working. Sinks won’t empty, and dirty water can back up. Cleaning the grease trap on time helps prevent it. We can set up 3, 6 or 12-monthly visits so nothing on a site in Portsmouth gets missed.
We do not list prices on the website, because each job is priced on what it involves. Call for a fixed quote, and we’ll talk you through it.

What happens on the day
Your staff don’t need to do much on the day. A contact on site lets us in at the agreed time and points us to the system, and we take it from there. Before we leave, the area is tidied and the paperwork follows. In Portsmouth, bigger jobs are often split over several out-of-hours visits.
- We agree a time when the sinks are not 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.
Preparing for the visit
- Clear the space around the work
- Plan for cooking equipment or plant to be off before we arrive
- Dig out any earlier paperwork for the system
Ask for a quote
Photos are the quickest way to a quote: wide shots of the system, close-ups of anything that worries you and how we’d get to it. Tell us what kind of site it is and when it’s open, and many jobs can be priced from that alone.

Aftercare tips
Results last longer with the right care. Here’s what we suggest:
- Don’t rely on hot water to clear grease
- Use strainers in the sink plugholes
- Book trap cleans at a set interval
- Scrape plates and pans into the bin before washing up
Once the trap is cleaned and refitted, the sinks can be used right away. We run water through to check it drains before we leave.
Fat that escapes the trap hardens in the pipework. Once it’s there, it needs a drainage contractor to clear, so it’s far better to keep the trap clean.
How we price grease trap cleaning
The diagnosis comes before the price. We look at:
- The condition we find in the survey
- One-off work versus a regular cycle
- Parking and loading at the site
- The size of the system
The price reflects the work, not guesswork. That’s why every job is surveyed first, and the price is agreed before any work starts.
What we need to know
There’s no need for technical detail. It helps if you can send:
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
- The site address and the type of premises
- How we’d reach plant on a roof or in a plant room
- Photos showing the whole system and its surroundings
Quoting starts with a diagnosis, either from photos and details you send or from a site visit. After that, you get a fixed price for the work, before any work starts.
