Your questions about grease trap cleaning in Wherwell
Who would carry out a food hygiene inspection at a kitchen in Wherwell?
The local authority for Wherwell is Test Valley council, and its environmental health team does the inspecting. Photos from a deep clean are a simple record of what was done and when.
Can the work in Wherwell be done at night or at weekends?
Yes, out-of-hours work is a big part of what we do. The work in Wherwell can fit around your hours. Let us know the hours you are closed and we’ll book within them.
What’s TR19?
TR19® is BESA’s specification for ventilation hygiene. TR19® Grease, a standalone specification since 2019, covers grease in kitchen extract systems, while TR19® Air covers other supply and extract ductwork.
How much time does a grease trap clean need?
Typically, it takes less than an hour for many under-sink units. A large or very full trap takes longer, and we’ll tell you in advance.
Can you set up regular visits?
Yes. Plans on a 3, 6 or 12-monthly cycle are available, to suit the system and how it’s used.
What happens to the waste?
We contain it and take it with us. Grease, debris and waste water are collected as the work goes on rather than letting it spread.
Do we lose a day’s trading?
Not normally. The area we are working in has to be out of use while we are there, so the visit goes in a quiet slot.
Which records should we keep?
Each report and certificate we give you, filed in the maintenance log, along with your own cleaning log. BESA says certificates should show the date, location and technician.
Grease trap cleaning for kitchens and businesses in Wherwell
A clean trap means flowing drains and no foul smells. The fat, oil, grease and solids are taken out, clean the inside and the baffles, and check the trap is working properly. Typical jobs include an inline trap or interceptor due for cleaning and gurgling drains in the kitchen, across inline grease traps, kitchen waste pipes and pot wash sinks.
In rural areas, a kitchen may drain to a private system rather than a public sewer, so keeping fat out with a working grease trap matters even more.
Each visit ends with a written report and pictures, so you have a record of what was done and when. Where the work is a TR19® Grease clean, the certificate is issued through the BESCA Vent Hygiene Elite portal.

Part by part
Inline grease traps
Inline traps often take waste from several sinks or appliances. That means more grease, so regular cleaning matters.
Baffles and outlets
Every clean includes the baffles, inlet and outlet so the trap works as it should.
For landlords and multi-site operators
Multi-site operators often want one contractor and one number. We cover South East England and London, so a run of sites can go into one programme and kept to a regular schedule.
Where a tenant occupies the premises but the landlord owns the building, the lease normally sets out who maintains what. We’re happy to deal with either side and send the paperwork to whoever needs it.

What your team can do, and what needs us
Day-to-day cleaning is something your team can do: wiping canopies, washing grease filters and recording it in a log. Inside the ducts, risers and fan is specialist work, and that is where we come in.
In-house cleaning and specialist cleaning do different jobs. A daily filter wipe and a weekly filter wash keep grease down at the front of the system, but grease that has passed the filters is out of reach. Reaching it takes a specialist with the right equipment.

Keeping the system healthy
Simple habits between visits make a real difference. We recommend:
- Hot water only moves grease further down
- Keep the grease trap on a regular cleaning schedule
- Keep access to the trap clear
- Act on gurgling or smelly drains
We will suggest when the trap should be cleaned again. That depends on how quickly it filled and how busy the kitchen is.
If the sinks are slow or smelly, the trap may be full. Getting it cleaned now can stop a full blockage down the line.
