Canopy and hood cleaning in Long Marston, Hertfordshire
For canopy cleaning in Long Marston, one call is all it takes, from survey to sign-off. Fully insured, with CHAS, SafeContractor and ISO 9001.
- Filters that clog soon after cleaning
- Fat running down the front of the hood
- A sticky, discoloured canopy
How the visit works
The first job on site is protection: sheeting goes over floors and surfaces close to the work. Then we make the system safe and start. It takes part of a shift for most kitchens, more where there are several canopies or heavy deposits, and the area is cleaned down before we leave. In a small place like Long Marston, the journey is planned ahead and the visit arranged around the site’s hours.
- We look at the canopy first, from pictures or on a visit.
- Equipment below is switched off and left to cool, then sheeted.
- With the filters out, the plenum and housing are cleaned back.
- The canopy is cleaned inside and out, including troughs and seams.
- Clean filters are refitted and before and after photos go into your report.
Getting ready for the visit
- Agree a time when the area can be out of use
- Clear loose items from the work area
- Have your last certificate or report to hand

Advice
How we handle canopy cleaning in Long Marston
Every canopy we clean in Long Marston gets the same treatment: we remove the filters, clean the plenum and housing, then degrease the canopy shell. Before and after photos go into your report. Common call-outs are for filters that clog soon after cleaning and a sticky, discoloured canopy, across plenum chambers, wall canopies and island canopies.
Rural kitchens often have long, low duct runs through a roof space or along an outside wall, and those horizontal sections are where grease settles. We agree access and timings in advance.
Every visit ends with a written report and pictures, so you have a record of what was done and when. Where the work is a TR19® Grease clean, the certificate is issued through the BESCA Vent Hygiene Elite portal.

What affects the cost of canopy cleaning
The price is fixed before any work begins. It’s based on:
- Whether we need access equipment or extra panels
- Whether it’s a one-off visit or part of a schedule
- How many systems or sites are involved
- Working hours and out-of-hours timing
When the work has to happen, how we reach it and how big the site is all affect the cost. We take each of them into account and give you a fixed price before we start.

What staff can safely do
Keep a record of what your team does. A dated log of in-house cleaning and checks shows an inspector that the system is looked after between visits, next to our reports.
Staff cleaning doesn’t replace a specialist visit; it supports it. Clean filters and tidy surfaces slow the build-up, but the parts you can’t see still need a specialist at the right interval.
Keeping the system healthy
Simple habits between visits make a real difference. We recommend:
- Clean the hood’s outer surfaces daily
- Check and empty canopy gutters regularly
- Avoid harsh scourers that scratch the canopy
- Leave the extract running until cooking stops
The report gives a recommended next clean date. That date is based on your cooking hours and what we found, in line with BESA guidance.
A daily wipe of the hood keeps fresh grease from baking on. It does not reach the plenum, but it stops the outside building up.
Canopy cleaning around Long Marston
The FSA’s food hygiene register includes about 3 pubs, bars and clubs in and around Long Marston, up to about a mile and a half out. Any of them serving cooked food has an extract to keep clean, from canopy to discharge. Food hygiene inspections in Long Marston are the job of Dacorum council’s environmental health team. They look at how clean the premises and equipment are, and the kitchen extract is part of that. Our report lists what was cleaned and when, which is useful to have ready. Long Marston is covered by Hertfordshire 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.
If you run catering at a healthcare site, such as a hospital like Tindal Centre about 4.4 miles west, the extract may need cleaning more often than a part-time kitchen. Historic houses near Long Marston, such as Ascott House about 4.3 miles north, are a reminder that older buildings with event kitchens can have long, awkward duct routes.

How the job changes from site to site
Plenums and filter housings
Behind neglected filters, the plenum can be heavily coated. We remove thick grease by hand, then degrease.
Wall canopies
A wall-mounted canopy runs along the back of the range. The joint between canopy and wall is a common grease trap, so we clean along it as well as the inner skin.
Why it’s worth doing now in Long Marston
A greasy canopy is fuel directly above the flame. Flames from the range can ignite it and be pulled further into the system, where a fire is much harder to stop. A clean canopy takes that fuel away. A planned visit to Long Marston is easier to arrange than an emergency callout.
The price reflects the work, not guesswork. That is why every job is surveyed first, and the price is agreed before work begins.

Common questions in Long Marston
Can you get to a site in Long Marston?
Yes. Villages and rural sites across the South East are part of our work, Long Marston included. Just mention lanes, gates or anything else about the site when you book.
Which fire service covers Long Marston?
Long Marston is in the area of Hertfordshire Fire and Rescue Service. TR19® is not law, but it’s the benchmark many fire officers and insurers look to when they ask how often the extract is cleaned.
Which accreditations do you hold?
Our accreditations are CHAS, SafeContractor and ISO 9001, alongside BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease. The Vent Hygiene Elite scheme is run by BESCA and audited independently.
Is TR19 a legal requirement?
No. The law sets the duty, and TR19® is the recognised benchmark for meeting it. Under the Regulatory Reform (Fire Safety) Order 2005, the responsible person has to manage fire risk, and without records, many insurers may refuse or reduce a claim.
What types of premises do you cover?
Restaurants and pubs, hotels, schools and colleges, hospitals and care homes, offices and retail, plus food production and leisure sites.
What about areas you cannot get to?
Anything we can’t reach goes on the report, with a note of where it is, and we explain what access is needed, for example new access panels.
What do you do to protect the area?
With sheeting and covers, before anything else happens. We keep the work contained and leave the area clean.
Can you set up regular visits?
Yes. Regular plans can run on 3, 6 or 12-monthly cycles, to suit the system and how it’s used.
Do you need canopy cleaning in Long Marston?
A canopy in Long Marston picks up grease at much the same rate as one anywhere else with the same cooking: it comes down to how long the kitchen cooks and what’s on the menu. High-heat cooking coats it fastest.
What we’re most often called out for:
- Grease channels that no longer drain
- Greasy streaks across the canopy
- Smoke hanging around the canopy during service
- Condensation running down the canopy
For schools such as Long Marston VA Church of England Primary School, kitchen extract cleaning is normally booked for the holidays, when the canteen is closed.
Questions to ask before you book
- Whether the whole system is included, or only the parts that are easy to reach
- Whether the price is fixed
- How they set the interval to the next visit
- Whether inaccessible sections are listed on the report
