Grease trap cleaning for kitchens and businesses in Knebworth
A neglected grease trap stops doing its job. Fat sets in the pipes downstream and the result is blocked drains and bad smells. Regular cleaning keeps it working. Common call-outs are for a kitchen drain that smells and a regular cleaning plan for the grease trap, across pot wash sinks, inline grease traps and school and care home kitchens.
Around a place like Knebworth, deep clean work tends to mean pubs, cafés and school or care home kitchens. Smaller kitchens still collect grease behind equipment and in the drains.
We are CHAS and SafeContractor accredited, we hold ISO 9001 and we are fully insured. We are also a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, trading since 2009.

Commercial kitchens in Knebworth
The FSA’s data shows about 14 bars, pubs and nightclubs registered within 1.5 miles or so of the middle of Knebworth. Pub and hotel kitchens get the same build-up behind equipment and in the grease trap as any other. In Knebworth, food businesses are inspected by environmental health officers from North Hertfordshire 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.
Lister Hospital, about 4.2 miles north, is the nearest hospital to Knebworth; healthcare kitchens cannot stop cooking, so deep cleans are worked around meal times. For schools such as Knebworth Primary and Nursery School, deep cleans and grease trap work are normally booked for the holidays. If you run a kitchen near Knebworth station with long trading hours, grease builds up faster behind equipment and in the trap.

Fixed quotes for grease trap cleaning in Knebworth
Sites vary more than people expect. The main factors:
- Working hours and out-of-hours timing
- The condition we find in the survey
- The scale of the work
- The number of sites or systems
Several systems or sites on one quote can make for a more efficient booking. Mention every system or site you need covered and we will price it together.
Asking for a quote
A few details help us quote accurately. When you get in touch, it helps to send:
- Where the plant sits or the system leaves the building, such as a roof or outside wall
- The postcode and the type of business
- Photos showing the whole system and its surroundings
- Close-ups of filters, grilles, hatches or access panels
Photos are the quickest way to a quote: wide shots of the system, close-ups of anything that worries you and how we’d get to it. Add the site type and your opening hours, and many jobs can be priced from that alone.
How it works
When we arrive, we check the system against the survey or the pictures you sent. If anything is different, we talk it through with the person on site before carrying on. From there, it takes an hour or so for an under-sink trap, longer for a larger unit. We plan the journey to Knebworth and bring what the job is likely to need.
- We agree a time when the sinks aren’t needed.
- The trap is opened up and checked.
- We remove the grease layer and settled solids.
- We clean the baffles, inlet and outlet.
- We close it up, check it drains and suggest when it needs cleaning again.
Preparing for the visit
- Arrange a key holder or contact on site
- Make sure equipment near the work can be switched off and left to cool
- Let us know when the site is closed or quiet
How to get a quote
There’s no standard price list, because every site is different. We look at your system first, from pictures or on a visit, then send a fixed quote. To get going, ring 0345 646 2711 or use the quote form.

Managing agents and facilities teams in Knebworth
If you look after several sites, we can plan visits across the whole estate and price them together. Every building has its own written report, so each one has its own record.
Multi-site operators often want one contractor and one number. We cover South East England and London, so visits at different addresses can be planned together and kept on a regular cycle.
Aftercare tips
Aftercare is simple, and it helps at the next visit:
- Avoid pouring boiling water down to shift grease
- Make sure the trap can be reached easily
- Keep strainers in every sink
- Scrape plates and pans into the bin before washing up
You will get our view on how often the trap needs cleaning. It’s based on how full it was and how busy the kitchen is.
Grease that gets past the trap sets in the drains. Clearing it then is a bigger job so prevention is the easier route.
Different parts, different methods
Restaurant and takeaway kitchens
Visits are booked when the sinks are not in use so the kitchen is not disrupted.
Under-sink grease traps
We empty and clean under-sink traps without disrupting the rest of the kitchen, and check the lid and seals.
Knebworth questions
Is Knebworth within the area you cover?
Yes, smaller places are covered as well as towns. Let us know about access, parking and anything unusual about getting there when you book.
Who would carry out a food hygiene inspection at a kitchen in Knebworth?
In Knebworth, it’s North Hertfordshire council that carries out food hygiene inspections. Keep the dates of your last deep clean and grease trap visit with your food safety records, ready if an officer asks.
How often should a grease trap be cleaned?
There’s no single answer. The interval depends on how quickly your trap fills and we will advise on timing.
How much does grease trap cleaning cost?
No two traps are quite the same, so we quote once we know what you have. We give you a fixed price, normally within one working day.
Does the report say when we need you again?
Yes. How often depends on use and condition and the report sets out why.
Can we book visits on a schedule?
Yes. Send details of the systems and how they’re used and we’ll propose a schedule with a fixed quote.
What paperwork should we keep on file?
Everything that shows the system is looked after: reports, certificates, photos and your own cleaning or check logs. One maintenance log per site keeps it simple.
What do you do with what you remove?
Anything we remove is contained as we work and taken away with us, from grease and debris to used cleaning water. We do not leave it behind.
In-house cleaning or a specialist?
Staff cleaning doesn’t replace a specialist visit; it supports it. Regular in-house cleaning slows the build-up, but the parts you can’t see still need a specialist at the right interval.
Away from the kitchen, the in-house job is mainly checking: clear grilles, a log of filter changes and reporting anything odd. The inside of ducts and units needs a specialist.
