Grease filter exchange in Coleman Green
Baffle filters and mesh filters both fill with grease. Once they’re clogged, airflow drops and the fan has to work harder. Regular exchange keeps the air moving. The work covers mesh filters, wall canopies and baffle filters, and common reasons people get in touch are a greasy plenum behind the filters and missing filters in the filter bank.
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. Access, parking and timings are agreed before the day.
Think of the report as the 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 and sits alongside the report.

Multi-site and managed buildings
Facilities teams in offices, schools and healthcare sites book us too in Coleman Green and across Hertfordshire. Larger estates can be phased building by building to keep disruption down.
Running several sites is easier with one contractor. We cover South East England and London, so a run of sites can go into one programme and kept to a regular schedule.
The process
The first job on site is protection: sheeting goes over floors and surfaces close to the work. After that, the system is made safe and the work begins. It takes a short visit, depending on how many filters the canopies hold, and we clear up before we go. Somewhere like Coleman Green, lanes, gates and parking are worth mentioning in advance.
- First, we check the canopies and the filters in them.
- We note any filters that are bent, damaged or missing.
- We exchange the dirty filters for a clean set.
- We check the filters are seated and the canopy is ready to use.
- Anything that needs attention, such as a greasy plenum, is pointed out.
How to prepare
- Clear loose items from the work area
- Dig out any earlier paperwork for the system
- Mention any parking or loading restrictions
Ask for a quote
Quoting starts with a diagnosis, from your pictures and details or, where that is not enough, a survey on site. After that, you get a fixed price for the work, before we start.

When something else is needed
In fairness, some problems need a different fix:
- A heavily greased plenum or canopy, which needs cleaning to TR19
- An extract that was undersized from the start
- A fan that’s failing or too weak for the system
Not sure which it is? You can give us a ring on 0345 646 2711, or send details by email and we will tell you honestly before booking.

Canopy filter housings
We check that filters sit snugly in the housing at each visit since a gap is a route for grease.
Mesh filters
Layers of mesh catch grease droplets. In a busy kitchen, mesh soon blocks, so they need changing often.
What affects the cost of grease filter exchange
The quote reflects the site in front of us. We take into account:
- Site rules, permits and inductions
- Whether it’s a one-off visit or part of a schedule
- The scale of the work
- The condition of the system
One small site or a whole estate, the quote is built the same way: the work involved, the access and the timing. You’ll have a fixed price before we start.
Asking for a quote
We can often survey from photos. Try to include:
- Problems your staff have spotted
- Any previous report or certificate
- Your opening hours and when the area is out of use
- Photos showing the whole system and its surroundings
Photos are enough for some jobs, while others need a look on site. Larger sites, and anything hidden behind walls, ceilings or floors, are normally surveyed first. Either way, the quote is fixed before any work is booked.
In-house cleaning or a specialist?
If your staff spot something between visits, like drips, unusual noise, smells or damaged filters, it’s best reported rather than tackled in-house. We’ll take a look and give you a fixed quote.
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. That is our job.
Why act early in Coleman Green
Leaving filters too long pushes more grease into the plenum and ducts. The ductwork then loads up faster and grease readings can rise between cleans. Planning a trip to Coleman Green ahead is easier for everyone than a rushed one.
Putting the work off seldom saves money. Build-up, wear and faults tend to get worse, not better, and a neglected system can mean more work. If you’re unsure, phone us on 0345 646 2711 or send us an email and we’ll give you an honest view and a fixed quote.
Why book with us
- A written report with pictures after each visit
- Fixed quotes from a survey or pictures
- Ventilation hygiene specialists since 2009
- CHAS, SafeContractor and ISO 9001

Grease filter exchange around Coleman Green
Food Standards Agency records include about 4 pubs and bars within roughly a mile and a half of the centre of Coleman Green. Where they serve hot food, their kitchen extracts need cleaning to TR19® like any restaurant’s. Fire safety in Coleman Green falls to Hertfordshire 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. Kitchens in Coleman Green get their food hygiene inspections from St Albans City council. A greasy canopy or dripping filters are the sort of thing an inspection can pick up. Keeping each certificate and photo report on file helps show the extract is looked after.
If you run catering at a healthcare site, such as a hospital like Hill End Hospital about 3.6 miles south, the extract may need cleaning more often than a part-time kitchen. Term dates shape school work: for a school like Beech Hyde Primary School and Nursery, an extract clean fits neatly into a half-term or summer break. Historic houses near Coleman Green, such as Shaw's Corner about 2.5 miles north, are a reminder that older buildings with event kitchens can have long, awkward duct routes.

Your questions about grease filter exchange in Coleman Green
Do you cover smaller places like Coleman Green?
Yes. Coleman Green is within the area we cover across London and the South East. The journey is planned ahead, so a few details about the route help.
Do you work at weekends in Coleman Green?
Yes, we can come after you close and finish before you open. Your customers, staff or residents in Coleman Green needn’t be disturbed. Tell us your opening hours when you ask for a quote.
How much notice should we give?
The more notice, the better, especially for out-of-hours work. Quotes normally come back within one working day, and there’s a 24/7 line for emergencies.
Does the law say we must follow TR19?
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.
Can we skip TR19 cleans if the filters are changed regularly?
No. Clean filters help keep grease down, but the ducts and plenum still need cleaning at the right interval.
Can damaged filters stay in the canopy?
Each filter is looked at when we exchange. Any that are bent or damaged are flagged since a poor fit lets grease past.
Do you offer maintenance contracts?
Yes. Regular plans can run on 3, 6 or 12-monthly cycles, depending on what the system needs.
How long will you be on site?
We’ll confirm the time with your quote. For a typical site, it takes less than an hour in most kitchens.
