Greater London · Grease trap cleaning
Underhill grease trap cleaning
Grease trap cleaning for Underhill, from a team that has been trading since 2009. Out-of-hours visits and 24/7 emergency callout.
- A grease trap that hasn’t been emptied in a long time
- Drains that gurgle and bubble
- A small trap that fills too quickly
What we do, step by step
A visit follows the same order every time: protect the area, make the system safe, do the work, tidy up and hand over the paperwork. The visit itself takes an hour or so for an under-sink trap, longer for a larger unit. Many London buildings have a managing agent, a security desk or a permit-to-work system, so tell us who to contact in Underhill.
- 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.
- We clean every part of the inside.
- We refit it, run water through and remove the waste.
How to prepare
- Agree a time when the area can be out of use
- Clear loose items from the work area
- Let us know about parking and loading
How to get a quote
Getting a quote does not take long. Call or email with a few details and you will typically have a fixed price within one working day. Where a survey is needed, we arrange a time that suits the site.

How we handle grease trap cleaning in Underhill
Grease trap cleaning keeps the drains running and the smells away. The fat, oil, grease and solids are taken out, clean the inside and the baffles and the trap checked before we leave. If you have sinks that drain slowly and drains clogged with fat, we can help, from restaurants and takeaways, school and care home kitchens and kitchen waste pipes onwards.
Across London, council environmental health teams inspect food businesses, and walls, floors, ceilings and equipment are all part of the picture. Kitchens in Underhill often book a deep clean before or after an inspection.
The sign-off is always in writing: a written report, dated and illustrated with photos, plus a certificate through the BESCA Vent Hygiene Elite portal when the work is a TR19® Grease clean. Any parts we couldn’t reach are recorded on it too.

Looking after it afterwards
Aftercare is simple, and it helps at the next visit:
- Tell us when sinks start draining slowly
- Collect waste cooking oil separately
- Keep strainers in every sink
- Wipe grease off pans before washing them
The waste we remove leaves with us. There’s no greasy waste left on site after the visit.
If the sinks are slow or smelly, the trap may be full. Getting it cleaned now can stop a full blockage down the line.
Do you need grease trap cleaning in Underhill?
In Underhill, as everywhere, grease traps are easy to forget. Hidden under a sink or in a floor it’s often left until there’s a problem.
The symptoms we’re asked about most are:
- Scheduled grease trap emptying
- A kitchen drain that smells
- Drains clogged with fat
- A slow-draining kitchen sink
Where a church or community hall near St John the Baptist Church, or anywhere in Underhill, has a kitchen used by volunteers, a periodic deep clean keeps it ready for the next event.
Questions to ask before booking
- Whether VAT is included
- When the next visit should be, and why
- What happens if part of the system can’t be accessed
- Their accreditations, such as BESCA Vent Hygiene Elite, CHAS or SafeContractor
Underhill questions
Can a school kitchen in Underhill be done out of term time?
Yes. The holidays are the usual time for school work. There are about 30 schools, colleges and universities on the FSA’s food hygiene register within about 1.5 miles of Underhill. Tell us your holiday dates and we’ll book the visit for when the site is empty.
Is parking a problem for work in Underhill?
Tell us where a van can stop near your site in Underhill, and about any building rules on loading. Where restrictions apply in the day, an evening or overnight visit normally gets round them.
Do you work with multi-site operators?
Yes. One number covers all your sites across London and the South East, and visits can be set on a regular cycle.
Will cleaning the grease trap fix a blocked drain?
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.
What paperwork should we keep on file?
Everything that shows the system is looked after: reports, certificates, pictures and your own cleaning or check logs. One maintenance log per site keeps it simple.
What types of grease trap do you clean?
We clean under-sink traps, inline traps and interceptors. Let us know what’s fitted and we will plan around it.
Where does the grease from the trap go?
The fat, oil, grease and solids we remove go with us. None of it goes back into the drains, of course.
Do you cover Underhill?
Yes. Underhill is part of the area we cover, within the South East and London area we cover.
Part by part
Under-sink grease traps
Under-sink units are easy to forget. When they fill, the sink slows and starts to smell.
Grease interceptors
Interceptors separate grease the same way, on a larger scale. Cooling water lets grease rise and solids settle.
What a clean will not put right
Before booking, it helps to know what’s not included:
- A unit that cannot cope with the kitchen’s output
- Drains that are cracked or have collapsed
- Leaking pipework or sink wastes, which need a plumber
Not sure which it is? You can give us a ring on 0345 646 2711 or email us and we’ll tell you honestly.
What we work on in Underhill

For landlords and multi-site operators
From a single site to a large estate, you get the same standard: diagnosis, a fixed price, work booked around your hours and a written report with pictures.
We work for landlords, managing agents and facilities managers as well as the people running the site. Shared systems, like a riser serving several units, need a clear agreement on who books the work, and we can quote for the whole system.
What affects the cost of grease trap cleaning
There’s no set price list, because no two systems are the same. The quote depends on:
- Any permits to work or inductions
- The condition of the system
- Whether several sites go on one quote
- Whether we need access equipment or extra panels
The price reflects the work, not guesswork. That is why we survey first, from photos or on site, and the price is agreed before any work starts.
What we need to know
When you contact us, these details help:
- Where the plant sits or the system leaves the building, such as a roof or outside wall
- When the site is open and when it’s quiet
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
- Your last certificate, test record or report
Quoting starts with a diagnosis, either from pictures and details you send or from a site visit. Then we send a fixed price, before any work starts.
Grease trap cleaning around Underhill
Food Standards Agency data counts about 108 restaurants, cafés and works canteens and about 43 sandwich bars and takeaways within about 1.5 miles of central Underhill. Wherever they wash pans and plates, fat heads for the drain unless a trap catches it. In Underhill, food businesses are inspected by environmental health officers from Barnet council. The state of floors, drains and hard-to-reach corners all feeds into the inspection. Photos and dates from each deep clean make a useful record. In London, deep cleans and grease trap work are usually done overnight, so the kitchen opens as normal the next day.
If you look after a school kitchen, at a school such as St Catherine's RC School or anywhere near Underhill, the holidays are the time for a deep clean or a grease trap clean. Historic houses such as Wyllyotts Manor (about 3.4 miles north) are part of the area around Underhill, and if you run event catering at a venue like that, a deep clean between seasons helps.
