Grease, kitchens and Monkswood
The FSA’s food hygiene register shows about 55 cafés, restaurants and staff canteens and about 13 takeaways and sandwich shops in and around Monkswood, up to about a mile and a half out. Where they cook under a canopy, a grease reading is the way to tell whether the extract is due a clean. Monkswood sits within the area of Hertfordshire Fire and Rescue Service. In most workplaces, including commercial kitchens, it’s the fire and rescue authority that enforces the Fire Safety Order. It’s Welwyn Hatfield council that sends environmental health officers to food businesses in Monkswood. Extraction counts as kitchen equipment, so its condition can come up on the day. Our report lists what was cleaned and when, which is useful to have ready.
If you run a church or community hall kitchen, near The Parish Church of St John or elsewhere in Monkswood, its extract still collects grease from every lunch and event. Bursars and site managers at schools such as Homerswood Primary and Nursery School tend to book extract cleaning for when the kitchen is empty.
Monkswood is about 2 miles north of Welwyn Garden City, in Hertfordshire.

TR19 inspection for kitchens and businesses in Monkswood
Many insurers ask for proof that kitchen extract systems are cleaned and inspected to TR19®. Missing records can lead to a claim being reduced or refused. A TR19 audit sets out the system’s condition, with readings and photos, for sites in Monkswood and the rest of Hertfordshire. The work covers pre-clean surveys, wet film thickness tests and post-clean checks, and people most often call us about sections of duct that can’t be reached and sites with gaps in their extract records.
In a small place like Monkswood, kitchens are often in older or extended buildings, with long single-storey duct runs, and those horizontal sections are where grease settles. We agree access and timings in advance.
It’s worth checking any contractor’s accreditations. We are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we hold CHAS, SafeContractor and ISO 9001, with full insurance on top.

Why act early in Monkswood
If there’s a fire or a claim, your insurer may ask for TR19 records. Without them, a claim can be reduced or refused. An up-to-date inspection report is a good place to start. Planning a trip to Monkswood ahead is easier for everyone than a rushed one.
Putting the work off seldom saves money. Problems in a system tend to grow, which can make the next visit longer. If you’re not sure what’s needed, phone us on 0345 646 2711 or use the quote form for straight advice and a fixed quote.

Landlords, agents and facilities managers
For anyone managing more than one site, we can plan visits across the whole estate and price them together. Each site gets its own report and pictures, so records stay tidy.
Records are where multi-site compliance often slips. Each visit ends with a dated report and photos, ready to show insurers, fire officers or EHOs.
Looking after it afterwards
Good habits slow the build-up between visits. Our tips:
- Never cook with filters missing
- Send TR19 audit reports to your insurer on request
- Report grease dripping from the canopy
- Clean grease off the canopy between professional cleans
Keep the verification report next to the certificate it relates to. The pair gives a clear record of the clean and the check.
Fit access panels where the survey finds sections can’t be reached, so every part of the duct can be cleaned.

Common problems we fix in Monkswood
Some parts of a system are hard to reach, and grease can be missed there clean after clean. An inspection of a system in Monkswood shows where access panels are missing, so panels can be fitted.
Signs it’s time to call us include:
- Extracts that may be over the 200 micron mean
- Systems that need surveying before cleaning
- Kitchen extract systems with no recent grease readings
- Sites with gaps in their extract records
If you run a café or takeaway near Welwyn North station, early starts and late finishes leave little time to clean, so overnight extract cleaning suits.
Questions to ask before booking
- How they set the interval to the next visit
- Whether the figure could change on the day
- Whether the whole system is included, or only the parts that are easy to reach
- Proof of insurance
Monkswood questions
Which fire authority looks after Monkswood?
Fire safety enforcement in Monkswood is handled by Hertfordshire Fire and Rescue Service. TR19® is not law, but it’s the benchmark many fire officers and insurers look to when they ask how often the extract is cleaned.
Which environmental health team covers Monkswood?
Food hygiene inspections in Monkswood are carried out by Welwyn Hatfield council. It helps to keep the extract cleaning records with your food safety paperwork, so they’re ready if asked for.
Can you look after several sites?
Yes. You deal with one contact for every site across London and the South East, and visits can be set on a regular cycle.
What happens to the waste?
Waste is contained during the work and removed when we leave, from grease and debris to used cleaning water. None of it is left on site.
What is a WFTT or DTT grease test?
WFTT and DTT are the two methods for measuring grease thickness, in microns. We take readings at set points from canopy to fan.
Do you have a 24/7 line?
Yes, day and night, every day of the year. Office hours are Monday to Friday, 8am to 6pm, and the emergency line covers the rest.
Are you accredited?
We hold CHAS, SafeContractor and ISO 9001, and we’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. Vent Hygiene Elite is run by BESCA and independently audited.
How often should grease be tested?
That varies with the kitchen’s daily use. BESA sets minimum cleaning intervals of 3, 6 or 12 months by daily use, and testing shows if your kitchen needs more.
What we do, step by step
Protection comes first: sheeting goes over floors and surfaces close to the work. Then we make the system safe and start. It takes anything from an hour for a small canopy and short duct to a good part of a day for a large site, and we clear up before we go. A few pictures of the system help us make the most of a visit to a place like Monkswood.
- Post-clean verification is booked once the clean is done.
- We open the access points used on the clean.
- We repeat the WFTT or DTT readings.
- We photograph each area to record how it was left.
- We report the findings and flag any areas that need more work.
Preparing for the visit
- Mention any locked doors, roof access or ceiling voids
- Mention any sign-in, permit or induction we need
- Dig out any earlier paperwork for the system
Get a fixed quote
The quickest way to a quote is to send photos: wide shots of the system, close-ups of anything that worries you and how we’d get to it. Tell us what kind of site it is and when it’s open, and many jobs can be priced from that alone.
Related advice
What your team can do, and what needs us
For ventilation and air handling systems, in-house care is mostly about checks: keeping grilles clear, noting unusual noise or smells and logging filter changes. Cleaning inside ducts and units is specialist work.
Staff cleaning does not replace a specialist visit; it supports it. Clean filters and tidy surfaces slow the build-up, but hidden parts of the system still need specialist attention.
