FAQs for Ayot St Lawrence
Will you come out to Ayot St Lawrence?
Yes. Ayot St Lawrence is within the area we cover across London and the South East. Photos of the system and directions to the site help us plan the visit.
Which council inspects kitchens in Ayot St Lawrence?
In Ayot St Lawrence, it’s St Albans City council that carries out food hygiene inspections. An officer may look up into the canopy, so clean filters on the day and a recent certificate on file both help.
Do you survey before quoting?
Yes, every time. We diagnose before we treat: the survey tells us what the system needs and how to reach it and the fixed quote is built on it.
What about areas you can’t get to?
The report shows them clearly. Often the fix is extra access, such as new panels in ductwork, which we can install.
What information do you need?
A short description and a few pictures, with the address and opening hours. We’ll ask for anything else we need.
How often should a kitchen extract be inspected?
Each report recommends when to test and clean next, taking the readings and the kitchen’s hours into account. A risk assessment based on measured grease should set the interval.
Why survey before a clean?
We survey, measure and photograph the system first. The survey can be done from photos and details or on site, as suits the job.
What is a WFTT or DTT grease test?
We measure the grease at set points with a WFTT or DTT test, and set against the TR19® Grease figures.
About our TR19 inspection in Ayot St Lawrence
Insurance policies often require evidence of TR19® cleaning and inspection. Missing records can lead to a claim being reduced or refused. Our TR19 audits give sites in Ayot St Lawrence and across Hertfordshire a clear record of the system’s condition. The work covers insurer audits, post-clean checks and access surveys, and the jobs we see most are post-clean verification after another contractor’s clean and insurers asking for TR19 evidence.
In a small place like Ayot St Lawrence, kitchens are often in older or extended buildings, with long single-storey duct runs, where grease settles in the flat sections. We agree access and timings in advance.
The paperwork matters as much as the work. Each visit is written up with pictures, listing what was done, anything we couldn’t reach and when the next visit is due. File it in your maintenance log so it’s to hand when an insurer or inspector asks.

What you pay depends on how big the system is, the condition it’s in and access to every part of it. You get a fixed price before any work starts, so there are no surprises.

What your team can do, and what needs us
Day-to-day cleaning is something your team can do: wiping canopies, washing grease filters and recording it in a log. What they cannot safely do is clean inside the ductwork, the fan or the risers, and that’s where we come in.
For ventilation and air handling systems, in-house care is mostly about checks: clear grilles, a log of filter changes and reporting anything odd. Cleaning inside ducts and units is specialist work.
How it works
We’re used to working while the site is closed. A lot of visits happen overnight or at weekends, so a kitchen or building can carry on as usual the next day. The visit itself takes anything from an hour for a small canopy and short duct to a good part of a day for a large site. Visits to a village like Ayot St Lawrence are booked in advance, at a time that suits whoever runs the site.
- Post-clean verification is booked once the clean is done.
- The same access points are opened up.
- We repeat the WFTT or DTT readings.
- We photograph each area to record how it was left.
- The results are reported, with anything missed flagged.
How to prepare
- Let us know about permits to work or site inductions
- Have your last certificate or report to hand
- Mention any locked doors, roof access or ceiling voids

What we’re called out for in Ayot St Lawrence
Menus, opening hours and cooking styles change over time, and more frying or longer hours mean more grease. A cleaning interval set years ago may no longer fit.
Most sites get in touch when they notice something like this:
- Systems that need surveying before cleaning
- Missing access panels found on survey
- Insurers asking for TR19 evidence
- Uncertainty over how often to clean
Historic houses near Ayot St Lawrence, such as Shaw's Corner about 0.2 miles south-west, are a reminder that older buildings with event kitchens can have long, awkward duct routes.
What your quote should include
- What happens if part of the system can’t be accessed
- Whether VAT is included
- Whether a survey comes first
- Proof of accreditation you can verify
Between visits
So the system stays in good health:
- Report grease dripping from the canopy
- Clean grease off the canopy between professional cleans
- Clean or swap grease filters as often as the kitchen needs
- Keep the route to access panels clear
Where sections couldn’t be reached, the report says where access panels would help. With panels fitted, the next clean can cover every section.
Keep certificates, reports and readings in one place so you can produce them quickly.
For landlords and multi-site operators
Managing agents often deal with us directly. Send the address, what’s needed and how access works, and we’ll send a fixed quote.
We also work for facilities teams across offices, schools and healthcare across Hertfordshire. Work can be phased by floor, building or site around the people who use them.

- Parking and loading at the site
- How many systems or sites are involved
- The scale of the work
Every site is different, so each one gets its own fixed quote. The size of the job, how we reach it, its condition and the working hours all play a part.
