Commercial kitchens in Flaunden
There are about 3 restaurants, cafés and canteens within roughly a mile and a half of the centre of Flaunden, according to the Food Standards Agency’s register. Wherever they wash pans and plates, fat heads for the drain unless a trap catches it. Food hygiene inspections in Flaunden are the job of Dacorum council’s environmental health team. An inspection covers the structure of the kitchen as well as the food. A record of each deep clean helps show the kitchen is kept in order. Flaunden, about 23 miles from central London, is within our usual area. Visits are booked around your hours, evenings and weekends included.
Historic houses such as Chenies Manor House (about 1.6 miles south) are part of the area around Flaunden, and if you run event catering at a venue like that, a deep clean between seasons helps. Hemel Hempstead Hospital, about 4.5 miles north-east, is the nearest hospital to Flaunden; healthcare kitchens cannot stop cooking, so deep cleans are worked around meal times.

Grease trap cleaning in Flaunden
Think of the grease trap as a filter for the kitchen’s drains. Kept clean, it does its job quietly, but neglected, it causes blockages and smells. A regular clean keeps it healthy. Typical jobs include a blocked kitchen drain caused by grease and washing-up water that won’t drain away, on under-sink grease traps, inline grease traps and restaurants and takeaways.
Rural kitchens may drain to a septic tank or a private drain rather than straight into a public sewer, so keeping fat out with a working grease trap matters even more.

Why it’s worth doing now in Flaunden
Once the trap is full, grease heads for the drain. There it sets and narrows the pipe until water cannot get through. Regular trap cleaning beats dealing with a blockage. Somewhere as small as Flaunden, losing a kitchen or building to a fault is felt by everyone who uses it.

Flaunden questions
Do you work overnight in Flaunden?
Yes, evening, overnight and weekend work is normal for us. Your customers, staff or residents in Flaunden needn’t be disturbed. Just call us on 0345 646 2711 or use the quote form with your opening times and we will plan around them.
Who would carry out a food hygiene inspection at a kitchen in Flaunden?
In Flaunden, it’s Dacorum council that carries out food hygiene inspections. How often a business is inspected depends on the council’s risk rating for it, so the kitchen needs to be ready at any time.
Who has the legal duty for fire safety?
That depends on who controls the premises. Under the Fire Safety Order 2005, it’s the responsible person, which may be the employer, owner, landlord, facilities manager or managing agent.
What does TR19 mean?
A BESA specification, with two parts that matter most here: TR19® Grease for kitchen extracts and TR19® Air for supply and extract systems. It isn’t law, but it’s the benchmark.
Can you look after several sites?
Yes. We work across South East England and London, so sites at different addresses can be planned together on one programme. Each site gets its own report and pictures.
How much time does a grease trap clean need?
Each trap is a little different, and you can expect it to take anything from under an hour to a few hours, depending on the trap. We’ll confirm when we quote.
What does a grease trap clean 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.
How regularly does a grease trap need emptying?
It varies. We look at how full the trap is and how quickly it fills and we will advise on timing.
For landlords and multi-site operators
Landlords, managing agents and facilities managers book us, not only the businesses that use the systems. Where a system serves more than one tenant, such as a shared riser, it helps to agree who arranges the work, and we can quote for the whole system.
Managing agents often deal with us directly. Tell us the site, the work and the access arrangements, and we’ll send a fixed quote.
When it’s something else
Not every problem is solved by grease trap cleaning, and we’d rather say so up front. It doesn’t solve:
- A leaking sink waste or trap connection
- Sewer problems outside the premises
- A unit that can’t cope with the kitchen’s output
If in doubt, call us on 0345 646 2711 or send us an email and we will say what we think.
Parts of the system we cover
- School and care home kitchens
- Under-sink grease traps
- Inline grease traps
- Kitchen waste pipes
- Restaurants and takeaways
- Pot wash sinks
Between visits
Think of this as the after-treatment advice, short and simple:
- Don’t store things on top of the trap
- Keep waste oil out of the drains
- Mention any increase in cooking
- Scrape plates and pans into the bin before washing up
Keep used oil out of the drains and the trap will not fill as quickly. It makes a real difference.
A trap that’s left too long stops catching grease. Regular emptying keeps it working and avoids a blockage.
What your team can do, and what needs us
Staff cleaning and specialist work are not the same thing. Wiping filters daily and washing them weekly keeps the visible parts in order, but grease that has passed the filters is out of reach. Reaching it takes a specialist with the right equipment.
Some jobs should never be done in-house: entering ducts, working on fans, testing dampers and taking grease readings need training, the right equipment and safe access. That is our job.
Common problems we fix in Flaunden
Waste cooking oil poured down the sink fills a grease trap far faster than washing-up. Even small amounts add up.
These are the problems we see most often:
- Drains clogged with fat
- Gurgling drains in the kitchen
- Washing-up water that won’t drain away
- A small trap that fills too quickly
If you look after a school kitchen, at a school such as St Clement Danes School or anywhere near Flaunden, the holidays are the time for a deep clean or a grease trap clean.
Questions to ask before booking
- What happens if part of the system cannot be accessed
- Whether the quote shows VAT
- Proof of insurance
- Whether the whole system is included, or only the parts that are easy to reach
What we do, step by step
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. The middle part takes longest, which takes less than an hour for many under-sink units. If the van will struggle with a lane or gateway near Flaunden, let us know and we’ll plan around it.
- A visit is booked around your service.
- The trap is opened up and checked.
- 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.
Before we arrive
- Arrange a key holder or contact on site
- Tell us the best time to work, such as after service or at a weekend
- Let us know how we reach the system, including roofs, risers and plant rooms
