Grease trap cleaning for kitchens and businesses in Preston
No two traps are quite the same. Under-sink units are small and fill quickly and larger traps hold more grease before they fill. We look at the trap, how much the kitchen uses it and how quickly it fills before suggesting how often it needs cleaning. We are often asked to deal with a full, neglected grease trap and a larger grease trap that needs emptying, across restaurants and takeaways, kitchen waste pipes and under-sink grease traps.
In a village or hamlet like Preston, commercial kitchens are few, perhaps a pub, a school or a care home. Wherever there is one, it needs its grease trap and hard-to-reach areas kept clean.
Insurers, fire officers and environmental health officers all look at records. That’s why every job is written up in a report with pictures, and grease extract cleans come with a TR19® certificate issued through the BESCA Vent Hygiene Elite portal.

What your team can do, and what needs us
If your staff spot something between visits, such as dripping grease, a noisy fan, a smell or a filter that will not come clean, they should report it rather than try to fix it. We can diagnose it and quote.
Logging matters as much as cleaning. A dated log of in-house cleaning and checks shows an inspector that the system is looked after between visits, alongside our reports.
When to call us in Preston
Hot water and detergent carry grease further than you’d expect. Once it cools, it sets in the pipework or the drain.
What we are most often called out for:
- A blocked kitchen drain caused by grease
- A slow-draining kitchen sink
- An under-sink trap that keeps filling up
- An overdue grease trap
Half-term is a good time for school kitchens, at schools like Preston Primary School for instance, to have the grease trap emptied and the kitchen deep cleaned.
Questions to ask before you book
- When they can work, and whether that is outside your opening hours
- Whether inaccessible sections are listed on the report
- What paperwork you get at the end
- Proof of accreditation you can verify
Other services in Preston
For landlords and multi-site operators
If you look after several sites, we can schedule visits across all of them on one quote. Every building has its own written report, so records stay tidy.
Under the Regulatory Reform (Fire Safety) Order 2005, the responsible person must assess and reduce fire risk, and that can be the employer, the owner, a landlord, a facilities manager or a managing agent. Where responsibility is shared, records matter even more.
What happens on the day
The visit has three parts: getting the area ready, doing the work and signing it off. Set-up means sheeting and making equipment safe, while signing off means the written report and pictures. Most of the time goes on the work itself, which takes anything from under an hour to a few hours, depending on the trap. Pictures of the system and its access let us plan the work in Preston before we set off.
- A visit is booked around your service.
- We open the trap and look at its condition.
- 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.
Getting ready for the visit
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
- Have your last certificate or report to hand
- Clear loose items from the work area
Getting a quote
Photos are enough for some jobs, while others need a look on site. Larger sites, and anything hidden behind walls, ceilings or floors, are normally surveyed first. Either way, the quote is fixed before any work is booked.

What grease trap cleaning looks like in Preston
The FSA’s food hygiene register includes about 4 pubs, bars and clubs within about 1.5 miles of central Preston. Pub and hotel kitchens get the same build-up behind equipment and in the grease trap as any other. Preston, about 29 miles from central London, is within our usual area. We work evenings, overnight and at weekends, so the visit fits around the site. Food hygiene inspections in Preston are the job of North Hertfordshire council’s environmental health team. They look at the cleanliness of the whole kitchen: walls, floors, ceilings and equipment. Having the dates of the last deep clean to hand saves digging for them on the day.
If you run a church or community hall kitchen, near Church of St Martin or elsewhere in Preston, a deep clean and an emptied grease trap before a busy season of events are worth booking. If you cater for weddings or events at a historic house in the area (Knebworth House is about 3.9 miles south-east), deep cleans can be fitted between bookings.

Questions from Preston
Do you work at weekends in Preston?
Yes, we can come after you close and finish before you open. It means the site in Preston keeps running as normal. Your opening times are the first thing we ask for.
Which council inspects kitchens in Preston?
Food hygiene inspections in Preston are carried out by North Hertfordshire council. Photos from a deep clean are a simple record of what was done and when.
What accreditations do you have?
CHAS, SafeContractor, ISO 9001 and BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease. We have been trading since 2009 and we’re fully insured.
Do you survey before quoting?
Yes. Every job is surveyed first, either from pictures and details you send or on a site visit. Then you get a fixed quote.
How much time does a grease trap clean need?
Most grease trap cleans take an hour or two in most kitchens, depending on the size and condition of the trap including checking it drains. It’s booked when the sinks are not needed.
Will you tell us when the next visit is due?
Yes. Every report includes a recommended date for the next visit, based on use and what we found.
Do you clean under-sink and inline grease traps?
We cover under-sink, inline and interceptor units. Each one is emptied, cleaned and checked in the same careful way.
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’ll say so and suggest a drainage contractor.
What a clean will not put right
Some problems need a different service or another trade:
- Drains that are cracked or have collapsed
- A trap undersized for the amount of cooking
- Drains that need jetting rather than trap cleaning
If you are not sure, just ring 0345 646 2711 or drop us a line and we’ll give you a straight answer.
Parts of the system we cover

- Restaurants and takeaways
- Kitchen waste pipes
- School and care home kitchens
- Under-sink grease traps
- Pot wash sinks
What the work involves, part by part
Baffles and outlets
The baffles hold back grease while water flows on. Grease clings to them, so we clean them.
Restaurant and takeaway kitchens
Kitchens that fry and wash up all day fill their traps quickly. They often need the most frequent cleaning.
Looking after it afterwards
Simple habits between visits make a real difference. Our advice:
- Report slow or smelly sinks early
- Don’t wait for a blockage to book a clean
- Never pour used oil down the sink
- Avoid pouring boiling water down to shift grease
The sinks are ready to use as soon as we’ve finished. Water is run through to check everything flows before we go.
If the kitchen has got busier, the trap fills faster. Shortening the cleaning interval now keeps the drains flowing.
