Your questions about kitchen extract cleaning in Holywell
Can you work in Holywell outside opening hours?
Yes, out-of-hours work is a big part of what we do. The site is handed back ready to open. Your opening times are the first thing we ask for.
Who enforces fire safety at workplaces in Holywell?
Holywell is in the area of London Fire Brigade. A recent cleaning certificate and a note of the next clean date show that grease in the extract is being managed.
Do you have a 24/7 line?
Yes, 24/7. Office hours are Monday to Friday, 8am to 6pm, with the emergency line covering every other hour.
What do you do with what you remove?
It’s contained and taken away. Grease, debris and waste water are collected as the work goes on, so it does not spread.
Are you accredited for kitchen extract cleaning?
As a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, our work sits within an independently audited scheme. We hold CHAS, SafeContractor and ISO 9001 too, and we are fully insured.
Which kinds of sites do you work on?
Commercial premises of every kind: from restaurants, pubs and hotels to schools, hospitals, care homes, offices, shops and food production sites. We fit the work around how the site operates.
How long will the clean take?
A small kitchen with a short duct can be done in a few hours, but large systems may be spread over more than one visit. Your quote says how long to expect.
Which parts of the extract do you clean?
The whole system: the canopy, the plenum behind the filters, the filters, horizontal ducts, vertical risers, the fan and the discharge, plus attenuators where fitted. Anything we can’t reach is recorded on the report.
Kitchen extract cleaning in Holywell
Has the extract gone a while without a clean, or has the paperwork gone missing? Just call us on 0345 646 2711, or send details by email with photos of the canopy and filters, and we’ll come back with a fixed price for the work in Holywell, typically within one working day. We’re often asked to deal with years of baked-on grease in the ducts and an overdue clean flagged by an EHO or fire officer, on canopies and hoods, plenums and filters and horizontal duct runs. Whether you call it kitchen extract cleaning, TR19 cleaning or kitchen duct cleaning, it’s the job we do every week across Greater London.
BESA sets minimum intervals by hours of cooking a day: 3-monthly for heavy use, 6-monthly for moderate use and yearly for light use, adjusted by what the grease readings show.
London kitchens are often tucked into basements or the back of a building, with extract ducts that can climb several floors to discharge at roof level. For a kitchen in Holywell, that typically means a longer system to clean and more access panels to plan around.
Think of the report as the system’s health record: dated, with pictures, and showing what was done. For TR19® Grease cleans, the certificate comes through the BESCA Vent Hygiene Elite portal and sits alongside the report.

Kitchen extracts in Holywell
Food Standards Agency records include about 28 pubs, bars and clubs and about 6 hotels, B&Bs and guest houses in Holywell and the streets around it, up to about 1.5 miles out. Breakfasts, bar meals and functions all put grease into the extract wherever they’re cooked. London Fire Brigade covers Holywell. Fire and rescue authorities enforce the Fire Safety Order in most non-domestic premises, and in a kitchen that fire risk includes the grease in the extract. London jobs usually start after the last service, with loading and roof access agreed with the building first.
Historic houses near Holywell, such as High Elms Manor about 4.1 miles north, are a reminder that older buildings with event kitchens can have long, awkward duct routes. Bursars and site managers at schools such as Westfield Academy tend to book extract cleaning for when the kitchen is empty.
Holywell is about 2 miles south-west of Watford, in Greater London.

Aftercare tips
Results last longer with the right care. We suggest:
- Wash or exchange the filters often
- Give the canopy a daily wipe
- Report grease drips, smells or fan noise straight away
- Empty any grease troughs or cups on the canopy
After cleaning, we re-test the same points we measured at the start, so you can see the difference in numbers as well as pictures. Your TR19 certificate is then issued through the BESCA Vent Hygiene Elite portal.
Stick to the cleaning interval on the certificate. BESA guidance links the minimum interval to daily cooking hours, so a change in hours may mean a change in interval, and grease readings will show it.

What we do, step by step
We are used to working while the site is closed. Evenings, nights and weekends are when much of our work happens, so a kitchen or building can carry on as usual the next day. On site, the work takes anything from a few hours to a full night, depending on the size of the system. Most London sites can’t stop for the day, so work in Holywell is usually done overnight, early in the morning or at weekends.
- Diagnosis comes first, with a survey of the system and how it’s reached.
- We record grease levels at set points, then fix the price.
- After the kitchen closes, we sheet the area and set up to contain grease and water.
- The treatment: heavy grease scraped out, then every part degreased to TR19® Grease.
- The sign-off: post-clean readings, a TR19 certificate and a photo report with the next clean date.
How to prepare
- Mention any sign-in, permit or induction we need
- Plan for cooking equipment or plant to be off before we arrive
- Let us know how we reach the system, including roofs, risers and plant rooms

When to call us in Holywell
What’s on the menu matters as much as how much is cooked. Fryers, grills and open flames throw much more fat into the extract than gentler cooking, which is why grease readings matter more than the calendar.
Any of these means the system needs a check-up:
- A kitchen taken over without any extract records
- Extraction mentioned at an environmental health visit
- Stale cooking odours from the system
- Heavy grease build-up inside the duct runs
Where a hall near St Oswald's Parish Church, or anywhere in Holywell, hosts lunch clubs or events, its extract gathers grease just as a café’s does.

Different parts, different methods
Extract fan and discharge
Attenuators, where fitted, can soak up grease and need attention. We clean what can be reached and note anything that can’t.
Canopy and plenum
The canopy catches the vapour, and the plenum behind the filters is where it first condenses. Both are scraped and degreased inside and out, including the filter housing.
For landlords and multi-site operators
We also work for facilities teams across offices, schools and healthcare across Greater London. Larger estates can be phased building by building around the people who use them.
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.
When something else is needed
Some problems need a different service or another trade:
- A grease trap that needs emptying
- A broken extract fan that won’t run
- Ductwork that is corroded, split or leaking (that’s for a ductwork contractor)
If you are not sure, just give us a ring on 0345 646 2711 or use the quote form and we’ll give you a straight answer before booking.

In-house cleaning or a specialist?
Keep a record of what your team does. A dated log of in-house cleaning and checks helps show that the system is managed between specialist visits, next to our reports.
Staff cleaning does not replace a specialist visit; it supports it. Regular in-house cleaning slows the build-up, but the parts you cannot see still need a specialist at the right interval.
