Why act early in Kingston
In Kingston, as anywhere, grease trap cleaning is a short, routine visit. Waiting for a blockage turns it into an urgent problem, often at a busy time. A visit arranged in advance is far less disruptive than a callout on a busy day.
Putting the work off seldom saves money. Problems in a system tend to grow, which can make the next visit longer. If you’re not sure what’s needed, call 0345 646 2711, or email photos for straight advice and a fixed quote.

Grease trap cleaning for kitchens and businesses in Kingston
Kitchens in Kingston use us for grease trap cleaning, whether it’s an under-sink unit or a larger inline trap. Visits are booked around your service so washing up is not interrupted. We’re often asked to deal with a regular cleaning plan for the grease trap and sinks that drain slowly, across kitchen waste pipes, under-sink grease traps and school and care home kitchens.
Kitchens around a smaller place like Kingston are often in older buildings, with drains and grease traps that have been there for years. Smells and slow drains are the usual warning signs.
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.

The process
The first job on site is protection: floors, worktops and anything near the work are covered. After that, the system is made safe and the work begins. The work on site takes an hour or two in most kitchens, depending on the size and condition of the trap, and the area is cleaned down before we leave. Everything the job in Kingston needs is worked out beforehand, from the survey.
- We find the trap and check how it’s connected.
- The sinks feeding the trap are kept out of use while we work.
- The trap is emptied of grease and food waste.
- We clean the chambers, baffles and connections.
- The trap is reassembled, checked for leaks and the waste taken away.
Getting ready for the visit
- Tell us the best time to work, such as after service or at a weekend
- Mention any sign-in, permit or induction we need
- Find the previous report, if there is one

Advice
Keeping the system healthy
Once we’ve finished, these simple steps help:
- Keep waste oil out of the drains
- Act on gurgling or smelly drains
- Avoid pouring boiling water down to shift grease
- Make sure the trap can be reached easily
Scrape plates into the bin before washing up. Sink strainers help catch solids before they reach the trap.
Grease that gets past the trap sets in the drains. Clearing it then is a bigger job so prevention is the easier route.
When something else is needed
Some problems need a different service or another trade:
- Leaking pipework or sink wastes, which need a plumber
- A trap undersized for the amount of cooking
- Sewer problems outside the premises
Not sure which it is? You can ring 0345 646 2711 or send us an email and we will tell you honestly.

Landlords, agents and facilities managers
When the building owner and the occupier are different, the lease normally sets out who maintains what. We can quote either party, and the report can go to both.
Facilities teams in offices, schools and healthcare sites book us too in Kingston and across Portsmouth. Larger estates can be phased building by building to keep disruption down.
Kingston: your questions answered
Which council inspects kitchens in Kingston?
Kitchens in Kingston are inspected by Portsmouth council’s environmental health officers. An officer may look behind equipment and at drains, so it pays to have the deep clean booked before those areas build up.
Do you work in villages like Kingston?
Yes, smaller places are covered as well as towns. A survey first, from photos or a visit, means we arrive with the right kit.
Do you work with multi-site operators?
Yes. Our area covers London and the South East, so we can schedule a run of sites on one programme. Each site gets its own report and pictures.
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 at any point.
Do we need to stop using the sinks while you work?
Just the sinks that drain into the trap, and only while we work. Visits are booked outside your busiest hours where we can.
Where does the waste go?
Anything we remove is contained as we work and taken away with us, including grease, debris and dirty water. We don’t leave it behind.
What does TR19 mean?
TR19® is the BESA specification for keeping ventilation systems clean. TR19® Grease, a standalone specification since 2019, covers grease in kitchen extract systems, and TR19® Air covers general supply and extract systems.
Will cleaning the grease trap fix a blocked drain?
It depends where the blockage is. A full trap is a common cause, and cleaning it can help but grease set further down the drains needs jetting by a drainage specialist.
Different parts, different methods
Inline grease traps
Inline traps are fitted into the drain line. They’re larger than under-sink traps but still need regular emptying.
Under-sink grease traps
Under-sink units are easy to forget. When they fill, the sink slows and starts to smell.
Grease trap cleaning in Kingston: local notes
Food Standards Agency records list about 6 food manufacturers and packers in Kingston and the streets around it, up to about 1.5 miles out. For food producers, the grease trap schedule should follow the volume going through it. In Kingston, food businesses are inspected by environmental health officers from Portsmouth council. 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.
If you run catering at a healthcare site, such as a hospital like St Mary's Hospital about less than half a mile south-east, deep cleans and grease trap visits are planned so meals still go out. For a café close to Fratton station, a deep clean can be done between closing and the morning rush.

When to call us in Kingston
Food scraps go down the sink with the washing-up water. It settles in the trap as solids and takes up space.
Signs it’s time to call us include:
- Drains clogged with fat
- Gurgling from the sink waste
- A full, neglected grease trap
- An under-sink trap that keeps filling up
If you run a church or community hall kitchen, near Church of St Cuthbert or elsewhere in Kingston, a deep clean and an emptied grease trap before a busy season of events are worth booking.
