Box Hill: your questions answered
Who carries out food hygiene inspections in Box Hill?
In Box Hill, it’s Mole Valley council that carries out food hygiene inspections. Ratings are published by the Food Standards Agency, so a clean extract and good records are worth keeping up.
Can you clean school kitchen extracts in Box Hill during the holidays?
Yes, out-of-term visits are normal for schools. There are about 2 schools, colleges and universities on the FSA’s food hygiene register within about 1.5 miles of Box Hill. Just ring 0345 646 2711 or send us an email with your term dates and we will plan around them.
What paperwork do you give after a duct clean?
A photo report, with readings and before and after pictures, plus a TR19 certificate for a full system clean. The report says when the next clean is due.
What if part of the duct cannot be reached?
We clean everything we can reach and record what we can’t. Fitting extra access panels is the usual answer, and we can do that for you.
Do you work with multi-site operators?
Yes. Send the list of sites and the work at each and we will quote them together.
What’s the cleaning interval for extract ductwork?
The duct is cleaned as part of the whole system, at intervals set by BESA guidance, ranging from 3-monthly to 12-monthly. Grease thickness testing shows whether that is often enough.
Do you look at the system first?
Yes, always. We diagnose before we treat: the survey tells us what the system needs and how to reach it and the fixed quote is built on it.
What happens to the waste?
Waste is contained during the work and removed when we leave, from grease and debris to used cleaning water. We do not leave it behind.
Ductwork cleaning for kitchens and businesses in Box Hill
Once air leaves the canopy, it travels through ductwork that most people never see. Grease settles along every metre of it and a fire in the duct can spread through the building. We clean it from the inside, through access panels, to BESA TR19® Grease. We are often asked to deal with grease seeping out of the duct seams and sections of duct with no access panels, across bends and junctions, horizontal duct runs and attenuators.
In a village or hamlet like Box Hill, the kitchens that need extract cleaning are usually a pub, a school, a care home or a hall kitchen, wherever there is one. Every one of them still needs its extract kept clear of grease.
Good records are part of the job. 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.

Aftercare tips
How long the results last depends on use and care. Here’s what we suggest:
- Book the next clean before the recommended date
- Ask us about extra access panels where sections can’t be reached
- Make sure filters are seated properly
- Report any grease dripping from duct joints
The report names every part of the duct that couldn’t be reached, with the reason. You can then decide whether to have access panels fitted.
Run the extract the whole time the kitchen is cooking. Moving air carries vapour through rather than letting it settle, so switching off early adds to the build-up.
What ductwork cleaning cannot fix
It’s worth knowing the limits before booking:
- A duct that is too small or badly routed for the kitchen (a design issue)
- A damper stuck open in the duct
- Ductwork that’s corroded, split or holed (that needs a ductwork contractor)
Not sure which it is? You can ring 0345 646 2711 or send us an email and we will tell you honestly before you book.

Other services in Box Hill
Different parts, different methods
Attenuators and discharge
Attenuators, where fitted, quieten the extract, but they can hold grease in their linings. We clean what can be reached and note anything that cannot.
Horizontal duct runs
A long flat run cannot be cleaned from one end. Where the gaps between panels are too long, we record what couldn’t be reached and can fit extra panels.
When to call us in Box Hill
A duct with too few access doors can’t be fully cleaned. Stretches with no way in may never have been touched, and grease there keeps thickening unseen.
The symptoms we are asked about most are:
- An insurer asking for TR19 evidence
- Thick deposits at the bottom of a vertical duct
- Stale grease odours from the duct
- Readings above 200 microns from a grease thickness test
If you cook for passing trade around Betchworth station, the extract can be cleaned between your last and first customer.

How we price ductwork cleaning
There’s no set price list, because sites vary so much. The quote depends on:
- How big the system is
- The times the site is available
- Access, including roofs, risers and ceiling voids
- A single visit or a regular plan
Putting the work off seldom saves money. Problems in a system tend to grow, which can make the next visit longer. If you’re not sure what’s needed, ring 0345 646 2711, or send details by email for straight advice and a fixed quote.
Helping us quote
What to send for a quote:
- The paperwork from the last visit, if you have it
- Problems your staff have spotted
- Wide pictures of the system and the area around it
- The roof, plant room or outside wall the system runs to
Quoting starts with a diagnosis, either from photos and details you send or from a site visit. Then we send a fixed price so you know the cost before we start.
The process
Protection comes first: sheeting goes over floors and surfaces close to the work. Then we make the system safe and start. The work on site takes anything from a few hours to several visits, depending on the length of duct, and we clear up before we go. If you can send photos, we can arrive in Box Hill knowing what to expect.
- We start by working out how the duct runs and where it can be opened.
- Grease readings are taken at set points along the duct.
- Access panels are opened and heavy deposits scraped out by hand.
- Next the ducts and risers are degreased, using whatever suits the deposit.
- Readings and pictures are repeated and any section we couldn’t reach is recorded.
How to prepare
- Dig out any earlier paperwork for the system
- Let us know how we reach the system, including roofs, risers and plant rooms
- Tell us where we can park and unload
Ask for a quote
For a fixed quote, call us on 0345 646 2711, or email photos and tell us the type of site, your opening hours and roughly what the system looks like. A few pictures and your last certificate or report help a lot. You’ll normally have a quote within one working day.

What happens if it’s left?
Old grease in a duct for a kitchen in Box Hill doesn’t stay soft. It bakes into a hard layer that takes far longer to remove, so the later the clean, the bigger the job. Systems in rural buildings are often out of sight and out of mind.
Working hours, access and the scale of the site can all change the price. We take each of them into account and give you a fixed price before work begins.

An officer looking round a kitchen will see the canopy, and grease there is hard to miss. Our report lists what was cleaned and when, which is useful to have ready. Surrey Fire and Rescue Service covers Box Hill. Its fire safety officers can audit commercial kitchens, and grease in the extract is part of a kitchen’s fire risk.
