What your team can do, and what needs us
Some jobs should never be done in-house: entering ducts, working on fans, testing dampers and taking grease readings need training, the right equipment and safe access. That’s our job.
If your staff spot something between visits, such as dripping grease, a noisy fan, a smell or a filter that will not come clean, it’s best reported rather than tackled in-house. We will take a look and give you a fixed quote.
TR19 inspection in Preston, done properly
After a clean, post-clean verification checks the result, with new readings and pictures of the cleaned areas. It gives you evidence of how the system was actually left. Typical jobs include heavy grease suspected in the plenum or ducts and an insurer’s request for a TR19 audit, on wet film thickness tests, access surveys and deposit thickness tests.
Rural kitchens often have long, low duct runs through a roof space or along an outside wall, where grease settles in the flat sections. Access, parking and timings are agreed before the day.
The paperwork matters as much as the work. Each visit is written up with photos, covering the work done, any areas we couldn’t access and a recommended next date. File it in your maintenance log so it’s ready for an insurer, fire officer or EHO.

Preston: your questions answered
Can a school canteen extract in Preston be done out of term time?
Yes, and it’s the easiest time to do it. There are about 2 schools, colleges and universities on the FSA’s food hygiene register within about 1.5 miles of Preston. You can ring 0345 646 2711, or send details by email with the dates the site is empty.
Do you work overnight in Preston?
Yes, out-of-hours work is a big part of what we do. The work in Preston can fit around your hours. Tell us your opening hours when you ask for a quote.
How do you protect the area?
Floors and surfaces near the work are sheeted before we start, and waste is contained as we go. At the end, the area is cleaned down.
How much notice should we give?
For planned work, earlier is better, particularly if your next visit is nearly due. Emergencies are different, because our line is open 24/7.
What types of premises do you cover?
Any site with a kitchen or a ventilation system to look after, from a small pub to a hospital. Hotels, schools, care homes, offices, shops and leisure sites are all part of our work.
Can we book visits on a schedule?
Yes. Scheduled maintenance plans are part of what we do, with visits at the interval your system needs. Each report recommends when the next visit should be.
What should I send you?
The site address, the type of premises and your opening hours, plus photos of the system and your last certificate or report if you have one.
Is a quote from pictures possible?
In many cases, yes. With good photos, the site type and your last report, we can price many jobs. Larger or hidden systems need a survey on site first.
How the job changes from site to site
Horizontal duct runs
Grease settles on the floor of horizontal ducts as the air cools. 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 affects the cost of TR19 inspection
The diagnosis comes before the price. The main factors are:
- The times the site is available
- One-off work versus a regular cycle
- How many systems or sites are involved
- 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. Call for a fixed quote and we’ll go through it with you.
Helping us quote
When you contact us, it’s useful to have:
- Any previous report or certificate
- Detail shots of panels, filters and grilles
- Your opening hours and when the area is out of use
- The roof, plant room or outside wall the system runs to
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. Add the site type and your opening hours, and we can price many jobs without a visit.
When something else is needed
An honest diagnosis matters more to us than a booking, so here’s what TR19 inspection won’t do:
- The grease itself, which needs a full or spot clean
- Hidden runs that need access panels first
- The legal duty, which stays with the responsible person
Not sure which it is? You can give us a ring on 0345 646 2711 or use the quote form and we will tell you honestly.
Parts of the system we cover
- Insurer audits
- Deposit thickness tests
- Wet film thickness tests
- Post-clean checks

Other services in Preston
Preston kitchens: local notes
The FSA’s data shows about 4 pubs and bars registered in Preston and the streets around it, up to about 1.5 miles out. A pub or hotel kitchen that cooks every day builds up grease in its extract like any other. The fire and rescue service for Preston is Hertfordshire Fire and Rescue Service. The Fire Safety Order puts the duty on whoever runs a kitchen to control its fire risk, and a greasy duct is fuel. It’s North Hertfordshire council that sends environmental health officers to food businesses in Preston. They look at how clean the premises and equipment are, and the kitchen extract is part of that. Before-and-after photos from each clean are a simple way to show the extract is in hand.
Healthcare kitchens can’t easily close, so their extracts are cleaned overnight or between meal services; the nearest hospital to Preston is Lister Hospital, about 3.3 miles east. A hall kitchen that only cooks for events, whether near Church of St Martin or elsewhere in Preston, still needs its extract cleaned, just less often. If your kitchen is in a listed or historic building, like the houses around Preston (Knebworth House is about 3.9 miles south-east), fitting access panels needs care.
Preston is about 3 miles south of Hitchin, in Hertfordshire. For TR19 inspection in and around Preston, please phone us on 0345 646 2711, or email photos for a fixed quote. We work across South East England and London, including Preston. Our area takes in 381 places across Hertfordshire, large and small. There’s also a page for Milton Keynes, about 22 miles away.
Work in SG4 follows the same survey, fixed quote and written report as everywhere else we cover. We cover sites on The Green, Church Lane and School Lane and nearby roads. Nearby, we also carry out TR19 inspection in Temple Dinsley (1 mile east), Poynders End (1 mile east), Langley End (1 mile south-east), Little Almshoe (1 mile north-east) and St Ibbs (1 mile north-east). We also work in nearby towns such as Hemel Hempstead (13 miles south-west), Stevenage (4 miles east), St Albans (11 miles south), Welwyn Garden City (9 miles south-east), Harpenden (7 miles south-west) and Hitchin (3 miles north).
Landmarks near Preston
Typical jobs here are in premises near The Red Lion Public House. Preston’s nearest station is Hitchin station, roughly 3.2 miles north of the centre. A little further out are North Hertfordshire Museum (2.8 miles north) and Lister Hospital (3.3 miles east). Open spaces near Preston include Purwell Ninesprings and Markham's Hill.
Why act early in Preston
Sites in Preston that have never measured grease can’t tell whether their cleaning interval suits the kitchen. Measured readings let a competent person set the interval. A planned visit to Preston is easier to arrange than an emergency callout.
The cost depends on the size of the system, what state it’s in and access to every part of it. You get a fixed price before work begins, so there are no surprises.

Multi-site and managed buildings
Keeping records across a portfolio is half the battle. Each visit produces a dated report with pictures, so you can show an insurer or inspector what was done at each site.
From a single site to a large estate, the standard is the same: diagnosis, a fixed price, work booked around your hours and a written report with photos.
What happens on the day
We’re 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. The visit itself takes a couple of hours for a typical kitchen extract system. Visits to a village like Preston 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.
Preparing for the visit
- Agree a time when the area can be out of use
- Tell us where we can park and unload
- Arrange a key holder or contact on site
