FAQs for Prestwood
Will you come out to Prestwood?
Yes, smaller places are covered as well as towns. Photos of the system and directions to the site help us plan the visit.
Do you work overnight in Prestwood?
Yes, out-of-hours work is a big part of what we do. Your customers, staff or residents in Prestwood needn’t be disturbed. Just phone us on 0345 646 2711, or email photos with your opening times and we will plan around them.
Is TR19 cleaning required by law?
No. The law sets the duty, and TR19® is the recognised benchmark for meeting it. Under the Fire Safety Order 2005, the responsible person must reduce fire risk, and without records, many insurers may refuse or reduce a claim.
What happens if you can’t reach some of it?
We never leave them off the paperwork. You’ll know exactly which parts weren’t reached and why, and we can quote to improve the access.
Do we lose a day’s trading?
Not normally. The area we are working in has to be out of use while we are there, so we book a time when it would be closed anyway.
Are the filters cleaned too?
We take them out, clean them and put them back. Between cleans, a filter exchange service can keep them in good order.
What do you need from me for a quote?
Where the site is, what it is and when it’s open, along with a few pictures and any previous report.
Which kinds of sites do you work on?
Restaurants and pubs, hotels, schools and colleges, hospitals and care homes, offices and retail, plus food production and leisure sites.

Multi-site and managed buildings
Running several sites is easier with one contractor. We cover South East England and London, so visits at different addresses can be planned together and kept to a regular schedule.
We also work for facilities teams across offices, schools and healthcare in Prestwood and across Buckinghamshire. Work can be phased by floor, building or site to keep disruption down.
How the visit works
At the end of the visit, someone from your team can look over the work with us. Anything we couldn’t reach or that needs attention is pointed out there and then, and the same goes into the written report. The visit takes a few hours, depending on the size of the canopy and how much grease has built up. Your opening hours decide when we come to Prestwood, not ours.
- We start by checking the canopy, filters and plenum.
- The range is turned off and allowed to cool before we cover it.
- We remove the grease filters and clean the plenum and filter housing.
- We degrease the canopy shell, its seams and the grease troughs.
- Clean filters are refitted and before and after photos go into your report.
How to prepare
- Make sure equipment near the work can be switched off and left to cool
- Tell us about site rules, permits or sign-in
- Let us know how we reach the system, including roofs, risers and plant rooms

Advice
Keeping the system healthy
Here’s the after-treatment advice, in brief:
- Use non-abrasive cloths on the hood
- Wipe the canopy down at close every day
- Never run the range with a filter out
- Clean the baffle filters often
We recommend when the canopy, or the whole system, should next be cleaned. It reflects how long the kitchen cooks and how much grease we removed, in line with BESA guidance.
Keep the fan running throughout service and for a short while after. Turning the fan off early lets vapour settle on the hood.
Honest limits
An honest diagnosis matters more to us than a booking, so here’s what this work can’t put right:
- Ductwork and fans beyond the canopy (those need a full TR19 clean)
- Filters that no longer seal in the housing
- A hood that does not cover the cooking line
If in doubt, ring 0345 646 2711 or use the quote form and we’ll say what we think before you book.
What we work on in Prestwood
- Canopy light fittings
- Baffle filters
- Island canopies
- Wall canopies
- Plenum chambers
- Grease gutters
What the work involves, part by part
School and staff canteen kitchens
Lighter cooking still leaves grease on the canopy. BESA guidance still sets a minimum interval for the whole system, and the canopy is part of it.
Grease troughs and gutters
Where a trough drains into a grease cup, we empty and clean that as well, and we’ll show staff where it is.
Canopy cleaning in Prestwood: the local picture
Food Standards Agency data counts about 15 restaurants, cafés and works canteens and about 3 takeaways and sandwich shops in Prestwood and the streets around it, up to about 1.5 miles out. Any of those kitchens with a canopy has a hood that needs cleaning inside and out. Prestwood is covered by Buckinghamshire Fire and Rescue Service. Fire and rescue authorities enforce the Fire Safety Order in most non-domestic premises, and in a kitchen that fire risk includes the grease in the extract. Environmental health officers from Buckinghamshire council inspect food businesses in Prestwood. Extraction counts as kitchen equipment, so its condition can come up on the day. A TR19® certificate and photo report after each clean gives you a record to show an inspector.
If you look after a school kitchen, at a school such as Prestwood Junior School or anywhere near Prestwood, the holidays are the usual time for a TR19® clean. Volunteers running a hall kitchen near Holy Trinity Church, or anywhere in Prestwood, may not know when the extract was last cleaned, and a grease test settles it.

When to call us in Prestwood
Grease does not build up any differently in Prestwood: the hours and the type of cooking decide how fast. Frying and grilling load a canopy far faster than steaming or boiling.
Clients typically contact us when they notice something like this:
- A sticky, discoloured canopy
- A filter housing caked in grease
- Fat running down the front of the hood
- Condensation and grease dripping together
Historic houses near Prestwood, such as Hughenden Manor about 3.4 miles south, are a reminder that older buildings with event kitchens can have long, awkward duct routes.
