About our TR19 inspection in Colnbrook
TR19® Grease says grease should not exceed a mean of 200 microns between cleans, while a reading of 500 microns or more anywhere calls for immediate spot cleaning. Testing is how you know where your system stands. If you have kitchens whose menu or hours have changed and ductwork where grease may be over the TR19 limits, we can help, from insurer audits, wet film thickness tests and deposit thickness tests onwards.
For a kitchen in or near Colnbrook, the visit is planned around opening hours and the journey, and the clean covers the whole system, as it would anywhere: canopy to discharge, then a TR19® certificate and a photo report.
The paperwork matters as much as the work. You get a written report with photos after each visit, covering the work done, any areas we couldn’t access and a recommended next date. Keep it with your fire safety records so it’s to hand when an insurer or inspector asks.

Landlords, agents and facilities managers
When the building owner and the occupier are different, the lease normally sets out who maintains what. We’re happy to deal with either side and send the paperwork to whoever needs it.
We also work for facilities teams across offices, schools and healthcare across Slough. Work can be phased by floor, building or site around the people who use them.

What we do, step by step
There are three stages on the day: set-up, the treatment itself and the sign-off. Set-up means sheeting and making equipment safe, and the sign-off is a written report with pictures. The middle part takes longest, which takes a morning or less for one kitchen, more where there are several systems. Visits to a village like Colnbrook are booked in advance, at a time that suits whoever runs the site.
- After the clean, we arrange a time to check the system.
- We open the access points used on the clean.
- Grease readings are taken again at set points.
- Photos are taken to show the condition after the clean.
- We report the findings and flag any areas that need more work.
Before we arrive
- Let us know about parking and loading
- Dig out any earlier paperwork for the system
- Clear the space around the work

Advice
Staff cleaning versus specialist work
Keep a record of what your team does. A dated log of in-house cleaning and checks shows an inspector that the system is looked after between visits, alongside our reports.
Your own staff can handle the daily basics: wiping down canopy surfaces, cleaning filters and keeping a simple log. What they can’t safely do is clean inside the ductwork, the fan or the risers, which is where we come in.
What a clean will not put right
Before booking, it helps to know what’s not included:
- The grease itself, which needs a full or spot clean
- The responsible person’s own fire risk assessment
- A faulty or failing extract fan
If in doubt, call 0345 646 2711 or drop us a line and we will say what we think.
Parts of the system we cover

Part by part
Horizontal duct runs
Flat duct runs collect grease along their base. We test at points along the run through access panels.
Restaurants, pubs and hotels
Heavy use under BESA guidance, 12 to 16 hours a day, means a clean at least every 3 months, with testing showing whether more is needed.
What TR19 inspection looks like in Colnbrook
Look up Colnbrook on the FSA’s food hygiene register and you’ll find about 25 restaurants, cafés and works canteens and about 13 takeaways in Colnbrook and the streets around it, up to about 1.5 miles out. Kitchens like these cook for very different hours, and grease testing shows which extracts need cleaning soonest. Royal Berkshire Fire and Rescue Service covers Colnbrook. Grease in a kitchen extract is a recognised fire risk, and the fire authority enforces the law on managing it in most commercial premises. It’s Slough council that sends environmental health officers to food businesses in Colnbrook. The cleanliness of the kitchen and its equipment, extraction included, is part of what they check. Before-and-after pictures from each clean are a simple way to show the extract is in hand.
For schools such as Colnbrook Church of England Primary School, kitchen extract cleaning is usually booked for the holidays, when the canteen is closed. If your kitchen is in a listed or historic building, like the houses around Colnbrook (Frogmore House is about 3 miles west), fitting access panels needs care. If you run catering at a healthcare site, such as a hospital like Upton Hospital about 3.2 miles north-west, the extract may need cleaning more often than a part-time kitchen.
Colnbrook is about 4 miles north of Staines-upon-Thames, in Slough. We provide TR19 inspection for commercial premises of every kind in Colnbrook and the rest of Slough. Across Slough, we cover 31 places, Colnbrook among them. There’s also a page for Guildford, about 16 miles away.
TR19 inspection in SL3 follows the same survey, fixed quote and written report as everywhere else we cover. You will find streets such as High Street, Rayners Close and Drift Way, and we cover them all for TR19 inspection. Other places close to Colnbrook include Poyle (1 mile south-east), Brands Hill (1 mile west), Horton (1 mile south-west), Stanwell Moor (2 miles south-east) and Ditton (2 miles west).

The closest station to Colnbrook is Sunnymeads station, roughly 1.7 miles south-west. A little further out are Windsor Castle (3.4 miles west) and Upton Hospital (3.2 miles north-west). Green spaces nearby include Uxbridge Moor and Staines Reservoirs.
Between visits
Think of this as the after-treatment advice, in brief:
- Keep TR19 certificates, readings and reports together
- Clean or swap grease filters as often as the kitchen needs
- Mention new equipment or longer hours at the next test
- Have the latest report ready for insurance renewals
Any access problems we found are listed with a suggested fix. With panels fitted, the next clean can cover every section.
Keep filters clean and in place. Missing or damaged filters let grease straight into the plenum.
Common questions in Colnbrook
Which environmental health team covers Colnbrook?
The local authority for Colnbrook is Slough council, and its environmental health team does the inspecting. An officer may look up into the canopy, so clean filters on the day and a recent certificate on file both help.
Who enforces fire safety at workplaces in Colnbrook?
It’s Royal Berkshire Fire and Rescue Service, which covers Colnbrook. Records of extract cleaning are a sensible thing to have ready if a fire safety officer carries out an audit.
Can you work evenings and weekends?
Yes, and that’s how we prefer to work. The visit is timed for when the area is not in use, such as late evening, overnight or a weekend.
Do you offer maintenance contracts?
Yes. Regular plans can run on 3, 6 or 12-monthly cycles, depending on what the system needs.
Is there a survey before the work?
Yes. For many sites, pictures and a few details are enough, and larger or hidden systems get a visit.
Is TR19 cleaning the law?
No. TR19® is a specification, not a statute. Without TR19 records, an insurance claim can be reduced or refused, so it matters in practice.
Do you have a 24/7 line?
Yes. Our emergency line runs 24/7 for anything that can’t wait until a planned visit. Ring any time and tell us what’s happened.
Do you work with multi-site operators?
Yes. You deal with one contact for every site in our area, and visits can be set on a regular cycle.
Why deal with it now?
If a kitchen in Colnbrook has been cleaned on the same calendar for years, there’s no way to know if that interval is right without measuring. Measured readings let a competent person set the interval. Equipment tucked in a roof space or outbuilding near Colnbrook rarely gets looked at unless someone books it.
Working hours, access and the scale of the site all affect the cost. Each of those is built into the quote, and the price is fixed before we start.
