About our canopy cleaning in Longmoor
Think of the canopy as the mouth of the extract. If it’s coated in grease, everything downstream gets more of it. Our diagnosis starts there, and the cure is a thorough clean of the hood, the plenum and the filter housing. If you have heavy deposits behind the grease filters and a hood coated in old grease, we can put it right, from wall canopies, canopy light fittings and island canopies onwards.
Work in a small place like Longmoor starts with a call to agree access and timings, and the clean itself is the same full TR19® job as in any town: canopy to discharge, then a TR19® certificate and a photo report.
The report is your system’s health record: dated, with pictures, and showing what was done. Grease extract cleans are also certificated to TR19® Grease through the BESCA VHE portal, ready for your insurer.

Your questions about canopy cleaning in Longmoor
Will you come out to Longmoor?
Yes. Villages and rural sites across the South East are part of our work, Longmoor included. Let us know about access, parking and anything unusual about getting there when you book.
Can the work in Longmoor be done at night or at weekends?
Yes, evening, overnight and weekend work is normal for us. It means the site in Longmoor keeps running as normal. Your opening times are the first thing we ask for.
Is there a survey before the work?
Yes, every time. Diagnosis comes before treatment: the survey shows what needs doing and what access we need, and the quote is based on that.
Do you offer maintenance contracts?
Yes. Send details of the systems and how they’re used and we’ll propose a schedule with a fixed quote.
What do you do with what you remove?
Anything we remove is contained as we work and taken away with us, from grease and debris to used cleaning water. We don’t leave it behind.
What information do you need?
The site address, the type of premises and your opening hours, along with a few pictures and any previous report.
Who has the legal duty for fire safety?
The law calls them the responsible person. It’s normally the employer, or whoever controls the building, and where several people have control, each can have duties. Your lease and fire risk assessment should make it clear.
How long will it take to clean the canopy?
Allow a few hours, depending on the size of the canopy and how much grease has built up. We will confirm how long when we quote.
Leave it or put it right?
A canopy clean in Longmoor now stops the grease spreading further. The work takes an hour or two for one small canopy, longer where there are several, out of hours so service carries on. Left alone, grease keeps moving into the plenum and duct. Planning a trip to Longmoor ahead is easier for everyone than a rushed one.
When the work has to happen, how we reach it and how big the site is can all change the price. We take each of them into account and give you a fixed price before we start.

Aftercare tips
Results last longer with the right care. We suggest:
- Check and empty canopy gutters regularly
- Give the canopy a wipe after service
- Report new drips or smells from the canopy
- Make sure filters sit tight in the housing
Anything worth knowing goes into the report: damaged filters, gaps around the housing or troughs that need emptying more often. We keep it to what matters.
Wipe the canopy surfaces at the end of each day. It won’t replace a professional clean, but it slows the build-up you can see.
When to call us in Longmoor
Most canopies have troughs or channels that catch running grease. If they’re not emptied, they fill and overflow, and grease ends up dripping from the canopy edge.
If you notice any of these, it’s worth a diagnosis:
- A hood coated in old grease
- Grease dripping from the canopy edge
- Smoke hanging around the canopy during service
- A greasy hood noticed by an inspector
Healthcare kitchens, like those at hospitals such as Chase Community Hospital (about 2.3 miles north), often cook for long hours, which puts them in BESA’s heavier-use bands.
What to look for in a quote
- Whether VAT is included
- Exactly which parts of the system are covered
- Proof of accreditation you can verify
- Whether a survey comes first
Landlords, agents and facilities managers
We work for landlords, managing agents and facilities managers as well as the people running the site. Shared systems, like a riser serving several units, need a clear agreement on who books the work, and we can quote for the whole system.
Records are where multi-site compliance often slips. Every visit ends with a dated report and pictures, so you can show an insurer or inspector what was done at each site.
Honest limits
Canopy cleaning can’t fix everything, and we’d rather say so up front. It will not put right:
- Poor airflow from a fan that needs repair
- Grease filters too damaged to refit (they need replacing)
- A canopy undersized for the equipment
If you’re not sure, just call 0345 646 2711 or email us and we will give you a straight answer.

How the visit works
The visit has three parts: 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 pictures. Most of the time goes on the work itself, which takes a few hours for most canopies. We agree a date with you, plan the drive to Longmoor and turn up when the site is quiet.
- The canopy is checked from photos or on a visit.
- Once the kitchen has closed, the cooking line is cooled and sheeted.
- We lift out the filters and scrape the plenum and housing.
- Inside and out, the hood and its troughs are cleaned.
- Filters are refitted, the area cleaned down and the photo report put together.
Before we arrive
- Mention any parking or loading restrictions
- Arrange a key holder or contact on site
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas

What staff can safely do
Some jobs should never be done in-house: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease call for the right kit, training and safe access. Leave those to us.
Staff cleaning and specialist work are not the same thing. A daily filter wipe and a weekly filter wash keep grease down at the front of the system, but grease that has passed the filters is out of reach. That part needs specialist access and equipment.
