Headley Down TR19 inspection
TR19 inspection in Headley Down from ventilation hygiene specialists trading since 2009. Evenings, overnight and weekends, plus a 24/7 emergency line.

What happens on the day
There are three stages on the day: getting the area ready, doing the work and signing it off. Getting ready means protecting surfaces and switching off what needs to be off, and the sign-off is a written report with photos. Most of the time goes on the work itself, which takes around an hour or two per canopy and duct system. Visits to a place like Headley Down are planned ahead, so we arrive with what the survey says the job needs.
- We agree a time when the kitchen is closed or quiet.
- We look over the canopy, plenum, ducts, fan and discharge.
- Grease thickness is measured at set points by WFTT or DTT.
- We photograph the test points and record any sections we can’t reach.
- The findings go into a report with readings, pictures and a recommended next clean.
Preparing for the visit
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
- Clear the space around the work
- Name a contact who can let us in at the agreed time

The quickest way to a quote is to send pictures: 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 many jobs can be priced from that alone.
Advice
TR19 inspection in Headley Down
Before any clean in Headley Down, we survey the canopy, plenum, filters, ducts, fan and discharge. We check where the access panels are and whether every section can be reached, and grease readings are taken at set points. Typical jobs include heavy grease suspected in the plenum or ducts and pre-clean surveys before a first TR19 clean, on access surveys, insurer audits and post-clean checks.
Around a smaller place like Headley Down, kitchen extracts tend to belong to pubs, cafés, takeaways and school or care home kitchens. A kitchen that cooks fewer hours still builds up grease, so the interval is set by hours of use and grease readings.
We’re CHAS and SafeContractor accredited, we hold ISO 9001 and we’re fully insured. We are also a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, trading since 2009.

What affects the quote in Headley Down
Some jobs are bigger than they look, and some smaller. What affects the quote:
- How many systems or sites are involved
- The size of the system
- The condition we find in the survey
- When the work can happen, such as evenings, overnight or weekends
Kitchens, offices, schools and hospitals are all priced 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.
What we need to know
There’s no need for technical detail. It helps if you can send:
- Where the plant sits or the system leaves the building, such as a roof or outside wall
- Your last certificate, test record or report
- Any access panels or hatches you can see
- Your opening hours and when the area is out of use

What the work involves, part by part
Schools, hospitals and care homes
Education kitchens need TR19 inspections like any other. Testing shows whether the interval suits.
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.
Managing agents and facilities teams in Headley Down
Records are where multi-site compliance often slips. Each visit produces a dated report with pictures, so you can show an insurer or inspector what was done at each site.
Running several sites is easier with one contractor. We work across London and the South East, so visits at different addresses can be planned together and kept on a regular cycle.
Why act early in Headley Down
Without readings, you are guessing when to clean. Any reading of 500 microns or more needs immediate spot cleaning under TR19® Grease, and you can only act on that if you’ve measured it. A planned visit to Headley Down fits your hours; an emergency does not.
Putting the work off seldom saves money. Build-up, wear and faults tend to get worse, not better, which can make the next visit longer. If you are not sure what’s needed, give us a ring on 0345 646 2711, or send details by email and we will give you an honest view and a fixed quote.

Questions from Headley Down
Which fire authority looks after Headley Down?
Hampshire and Isle of Wight Fire and Rescue Service is the fire and rescue service for Headley Down. If a fire safety officer visits a commercial kitchen, they may ask about the fire risk assessment and how the extract is kept clean.
Can you come to Headley Down after we close?
Yes. We work evenings, overnight and at weekends. Your customers, staff or residents in Headley Down needn’t be disturbed. Your opening times are the first thing we ask for.
What is post-clean verification?
Verification means repeat readings and pictures once the clean is done. The report flags anything missed.
Can you price the work without visiting?
In many cases, yes. With good photos, the site type and your last report, we can price many jobs. Where we cannot see enough, we arrange a survey.
What do the grease readings need to be?
Under TR19® Grease, the mean thickness should not exceed 200 microns between cleans. Any reading of 500 microns or more needs immediate spot cleaning.
Do you work with multi-site operators?
Yes. You deal with one contact for every site in our area, with visits on a regular schedule.
Can you inspect our extract for our insurance company?
Yes. Insurers often want evidence the extract is managed to TR19®, and our audit gives a clear record of the system’s condition, with recommendations where something needs doing.
Can you come out in an emergency?
Yes. There’s a 24/7 emergency line, for problems that cannot wait. Call us any time and explain what’s happened.
What we are called out for in Headley Down

- Systems cleaned on a calendar with no measurements
- Systems that need surveying before cleaning

A hospital like Chase Community Hospital, about 2.8 miles west, is the kind of site where a kitchen may cook for patients, staff and visitors all day.

- Whether VAT is included
- Whether the whole system is included, or only the parts that are easy to reach
- Proof of insurance

- Fire safety duties beyond the extract system
- Removing the grease, which is a separate clean
- Ductwork that was designed or installed badly
