Grease trap cleaning in St Mary's, done properly
Every trap is different. Under-sink units are small and fill quickly, while inline traps and interceptors hold more. We assess the trap and how fast it fills and suggest an interval that suits. If you have an inline trap or interceptor due for cleaning and gurgling from the sink waste, we can help.
For a kitchen near St Mary's, deep cleans are booked around opening hours, often on a closed day.
The sign-off is always in writing: a written report, dated and illustrated with photos, and for TR19® Grease cleans, a certificate issued through the BESCA VHE portal. It shows what was done and what, if anything, couldn’t be reached.

What staff can safely do
Logging matters as much as cleaning. A simple log of filter washes, wipe-downs and checks shows an inspector that the system is looked after between visits, alongside our reports.
Good housekeeping makes our visits easier, not unnecessary. Regular in-house cleaning slows the build-up, but hidden parts of the system still need specialist attention.
How we price grease trap cleaning
There’s no set price list, because no two systems are the same. What we look at:
- Whether several sites go on one quote
- Travel, parking and unloading
- Working hours and out-of-hours timing
- What state the system is in
One small site or a whole estate, the quote is built the same way: what needs doing, how we get to it and when. You’ll have a fixed price before work begins.
What to send for a quote
There’s no need for technical detail. It helps if you can send:
- Close-ups of filters, grilles, hatches or access panels
- How we’d reach plant on a roof or in a plant room
- Your opening hours and when the area is out of use
- The site address and the type of premises
For a fixed quote, phone us on 0345 646 2711 or send us an email and tell us the type of site, your opening hours and roughly what the system looks like. Photos and the last report, if you have one, make the quote quicker. We normally come back within one working day.
For landlords and multi-site operators
Facilities teams in offices, schools and healthcare sites book us too in St Mary's and across Southampton. Work can be phased by floor, building or site around the people who use them.
Where a tenant occupies the premises but the landlord owns the building, the lease normally sets out who maintains what. We can quote either party and send the paperwork to whoever needs it.
Why it’s worth doing now in St Mary's
A full grease trap lets grease through to the drains. There it sets and narrows the pipe until water cannot get through. Cleaning the trap regularly is far easier than clearing a blocked drain. When a site near St Mary's shuts unexpectedly, the people who rely on it notice at once.
No two sites are the same, so we price each one individually. Size, access, the condition of the system and when we can work all make a difference.

Aftercare tips
After the visit, a few habits help the work last:
- Do not wait for a blockage to book a clean
- Collect waste cooking oil separately
- Report slow or smelly sinks early
- Don’t store things on top of the trap
Scrape plates into the bin before washing up. Use strainers in the sink plugholes before they reach the trap.
An overfull trap lets grease pass. Regular emptying keeps it working and saves a call-out for a blocked drain.
Your questions about grease trap cleaning in St Mary's
Which environmental health team covers St Mary's?
Food hygiene inspections in St Mary's are carried out by Southampton council. How often a business is inspected depends on the council’s risk rating for it, so the kitchen needs to be ready at any time.
Do you work overnight in St Mary's?
Yes, nights and weekends are routine for us. The work in St Mary's can fit around your hours. When you call 0345 646 2711 or use the quote form, mention when the site is quiet.
What’s the right interval for grease trap cleaning?
That depends on the trap and the kitchen. Small under-sink units fill faster than larger traps and the busier the kitchen, the faster it fills. We’ll suggest an interval after the first clean.
What happens to the waste?
It leaves the site with us at the end of the visit. While we work, it’s kept contained so the area stays clean.
Do you work in St Mary's?
Yes. We cover St Mary's and across Southampton, as part of our work across South East England and London. To book, give us a ring on 0345 646 2711 or use the quote form.
Will cleaning the grease trap fix a blocked drain?
Cleaning the trap deals with the grease it holds and that may solve a slow drain caused by the trap. Blockages further down the drain, or damaged pipework, need a drainage contractor.
What about areas you can’t get to?
We record them on the report, with a note of where it is, and we explain what access is needed, such as extra access panels in ductwork.
What accreditations do you have?
We are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. CHAS, SafeContractor and ISO 9001 are in place too, and we carry full insurance.

The process
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 the rest is down to us. Afterwards, the area is left tidy and the written report follows. Everything the job in St Mary's needs is worked out beforehand, from the survey.
- We locate the trap and check how it’s fitted.
- Sinks feeding the trap are taken out of use.
- We empty out the fat, oil, grease and solids.
- We clean every part of the inside.
- We refit it, run water through and remove the waste.
Getting ready for the visit
- Agree a time when the area can be out of use
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
- Mention any parking or loading restrictions
Getting a quote
Every quote begins with a look at the system, from your photos and details or, where that is not enough, a survey on site. After that, you get a fixed price for the work so you know the cost before work begins.
