What we are called out for in New Denham
As hot, greasy air travels up the duct, it cools and leaves a film behind. The thickest layers can sit out of sight in the plenum, at bends and along flat runs.
Common reasons sites call us are:
- Insurers asking for TR19 evidence
- Sites with gaps in their extract records
- Surveys needed before quoting a full clean
- Extracts that have never been grease tested
Older buildings often hide long, awkward duct runs, and if you run a kitchen at a historic venue in the area (Ickenham Hall is about 2.1 miles east), access may need planning.
What your quote should include
- Their accreditations, such as BESCA Vent Hygiene Elite, CHAS or SafeContractor
- If the quote is a fixed price or an estimate
- Whether they’re fully insured
- How areas they cannot reach will be recorded
About our TR19 inspection in New Denham
Under TR19® Grease, the mean grease thickness should stay at or below 200 microns between cleans, while a reading of 500 microns or more anywhere calls for immediate spot cleaning. Grease testing shows which side of those lines you are on. The work covers post-clean checks, insurer audits and access surveys, and people most often call us about an insurer’s request for a TR19 audit and sections of duct that can’t be reached.
Work in a small place like New Denham starts with a call to agree access and timings, and the clean covers the whole system, as it would anywhere: canopy to discharge, then a TR19® certificate and a photo report.
Nothing is signed off by word of mouth: a dated report with photos of the work, plus a certificate through the BESCA Vent Hygiene Elite portal when the work is a TR19® Grease clean. Any parts we couldn’t reach are recorded on it too.

How the job changes from site to site
Restaurants, pubs and hotels
A kitchen running from breakfast to late service builds grease quickly. Readings show if the cleans are frequent enough.
Horizontal duct runs
Bends and long runs can hold heavy deposits, well away from where anyone looks.
Why deal with it now?
A pre-clean survey avoids surprises on the night. Access problems are spotted in advance rather than on the night, and the quote reflects the real job. With notice, the visit to New Denham can be fitted around your bookings and events.
One small site or a whole estate, we price it on the same basis: the work involved, the access and the timing. The price is fixed before work begins.

Multi-site and managed buildings
Multi-site operators often want one contractor and one number. We cover South East England and London, so visits at different addresses can be planned together and kept on a regular cycle.
The Fire Safety Order 2005 puts the duty to manage fire risk on the responsible person, which may be the employer, owner, landlord, FM or managing agent. Where responsibility is shared, records matter even more.
Kitchen extracts in New Denham
The FSA’s data shows about 24 pubs, bars and clubs registered within about 1.5 miles of central New Denham. Wherever they cook, the canopy, duct and fan collect grease just as a restaurant’s do. The fire and rescue service for New Denham is Buckinghamshire 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. In New Denham, food businesses are inspected by environmental health officers from Hillingdon council. An officer looking round a kitchen will see the canopy, and grease there is hard to miss. Before-and-after pictures from each clean are a simple way to show the extract is in hand.
Term dates shape school work: for a school like Hermitage Primary School, an extract clean fits neatly into a half-term or summer break. Healthcare kitchens can’t easily close, so their extracts are cleaned overnight or between meal services; the nearest hospital to New Denham is Hillingdon Hospital, about 2.2 miles south-east.

When something else is needed
We’d rather tell you now than book work that will not help, so here are the limits:
- Fan breakdowns, which need a repair visit
- The responsible person’s own fire risk assessment
- Hidden runs that need access panels first
Not sure which it is? You can call 0345 646 2711 or email us and we’ll tell you honestly before you book.
Where we work
- Deposit thickness tests
- Post-clean checks
- Wet film thickness tests
- Insurer audits
- Pre-clean surveys
- Access surveys
What your team can do, and what needs us
Staff cleaning does not replace a specialist visit; it supports it. Regular in-house cleaning slows the build-up, but hidden parts of the system still need specialist attention.
If your staff spot something between visits, such as dripping grease, a noisy fan, a smell or a filter that won’t come clean, it’s best reported rather than tackled in-house. We will take a look and give you a fixed quote.
New Denham questions
Which environmental health team covers New Denham?
That is Hillingdon council, whose environmental health officers carry out food hygiene inspections in New Denham. Ratings are published by the Food Standards Agency, so a clean extract and good records are worth keeping up.
Can you work in New Denham outside opening hours?
Yes, we can come after you close and finish before you open. The site is handed back ready to open. Your opening times are the first thing we ask for.
What do you need from me for a quote?
Just the basics: where it is, what kind of site, when it’s open and the access. Photos and the last report help too. Then call 0345 646 2711 or send us an email.
Do you look at the system first?
Yes. Photos often do the job, and larger or hidden systems get a visit.
Do we have to follow TR19 by law?
No, TR19® isn’t legislation. The Fire Safety Order 2005 still requires the responsible person to manage fire risk, which in a kitchen includes grease in the extract. Many insurers also expect TR19 cleaning.
Do you cover New Denham?
Yes. We work across Greater London, Surrey, Kent, Sussex, Hampshire, the Isle of Wight, Berkshire, Buckinghamshire, Oxfordshire, Hertfordshire and Essex, and that includes New Denham.
Where does the waste go?
It leaves the site with us at the end of the visit. During the work, it’s contained so the area stays clean.
What does TR19 inspection cost?
The cost depends on the size of the system, its condition, access and timing. Ask us for a fixed quote, usually ready within one working day.
The process
Your trading hours come first. We book the visit for a time the area is closed, whether that is an evening, overnight or a weekend. Once we’re in, the area is sheeted and anything that has to be off is turned off and cooled, and the work takes a couple of hours for a typical kitchen extract system. We agree a date with you, plan the drive to New Denham and turn up when the site is quiet.
- First we look at the system’s cleaning history, if there is one.
- The layout is traced from the canopy to the discharge.
- Access panels are located and any missing ones noted.
- Grease readings are taken and photos recorded.
- You get a report and a fixed quote for the clean.
Preparing for the visit
- Mention any locked doors, roof access or ceiling voids
- Let us know about permits to work or site inductions
- Name a contact who can let us in at the agreed time
Getting a quote
Photos are the quickest way to a quote: 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.
