How we price TR19 inspection
We don’t publish a price list, because no two systems are the same. The quote depends on:
- A single visit or a regular plan
- When the work can happen, such as evenings, overnight or weekends
- The size of the system
- The condition we find in the survey
Whatever the type of site, the quote works the same way: the size of the job, access, condition and working hours. Ask for a fixed quote and we’ll explain each part.
What to send for a quote
Before you ask for a quote, gather:
- The roof, plant room or outside wall the system runs to
- Close-ups of filters, grilles, hatches or access panels
- Photos showing the whole system and its surroundings
- The paperwork from the last visit, if you have it
For a fixed quote, call us on 0345 646 2711 or use the quote form and tell us the type of site, your opening hours and roughly what the system looks like. Photos and the last report, if you have one, make the quote quicker. You will usually have a quote within one working day.
How we handle TR19 inspection in Lewknor
A fixed schedule doesn’t always match how a kitchen really cooks. Some kitchens build up grease faster than the minimum intervals assume, and only measurement shows it. Our readings give your risk assessment real numbers to work from. Common call-outs are for an insurer’s request for a TR19 audit and kitchens whose menu or hours have changed, on post-clean checks, deposit thickness tests and access surveys.
In a village or hamlet like Lewknor, the kitchens that need extract cleaning are normally a pub, a school, a care home or a hall kitchen, wherever there is one. Each still has a canopy and duct that collect grease, whatever the size of the place.
A written report with pictures follows every visit, so there’s a dated record of the work. Where the work is a TR19® Grease clean, the certificate is issued through the BESCA Vent Hygiene Elite portal.

Common problems we fix in Lewknor
You can’t judge grease thickness by eye. Clean filters can hide a heavy layer behind them, which is why readings matter.
Look out for these warning signs:
- Insurers asking for TR19 evidence
- Extracts that may be over the 200 micron mean
- Post-clean verification after another contractor’s clean
- Surveys needed before quoting a full clean
School kitchens, at schools like Lewknor Church of England Primary School for example, are usually cleaned in the holidays so no lunches are lost.

Why it’s worth doing now in Lewknor
Sites in Lewknor that have never measured grease cannot tell whether their cleaning interval suits the kitchen. Measured readings let a competent person set the interval. A fault that closes a site in a village like Lewknor affects everyone who depends on it.
Several systems or sites on one quote often makes better use of the time. Mention every system or site you need covered, and you will get one fixed quote.

What staff can safely do
Your own staff can handle the daily basics: wiping canopies, washing grease filters and recording it in a log. Inside the ducts, risers and fan is specialist work, which is where we come in.
Some jobs should never be done in-house: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease need training, the right equipment and safe access. Leave those to us.
Looking after it afterwards
So the system stays in good health:
- Flag oily drips near the extract
- Book the next test on the date in the report
- Do not box in or cover duct access panels
- Keep canopy edges and gutters wiped down
For an insurer audit, send them the report as it is, with readings, pictures and any areas not accessible.
Keep all TR19 records together so the history is easy to show.

FAQs for Lewknor
Can the work in Lewknor be done at night or at weekends?

Do you cover smaller places like Lewknor?

At what point does grease need cleaning?
Between cleans, the mean should stay at 200 microns or below, and anywhere at 500 microns or more needs spot cleaning right away.
Can you set up regular visits?
Yes. Regular plans can run on 3, 6 or 12-monthly cycles, to suit the system and how it’s used.
Do you work with multi-site operators?
Yes. One number covers all your sites across London and the South East, and visits can be set on a regular cycle.
What do you do with what you remove?
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.
Can you quote from pictures?
Often, yes. With good pictures, the site type and your last report, we can price many jobs. Larger or hidden systems need a survey on site first.
Do you check other contractors’ cleans?
After a clean, we take new readings and pictures to show how the system was left. It works whoever carried out the clean.
