Grease Filter Exchange in St Nicholas
Grease filter exchange for St Nicholas and the surrounding area: diagnosis first, then a fixed quote, the work and a report with photos. Ask us for a fixed quote.
- Filters that come out of the sink still dirty
- Damaged filters letting grease past
- A canopy running with filters missing
Looking after it afterwards
A little care between visits keeps the system in better shape. Our advice:
- Clear anything stored on or near the canopy
- Tell us if a filter is bent or damaged
- Never leave gaps in the filter bank
- Don’t let the full clean slip because filters are changed
Nothing changes for your staff, except one less greasy job. Make sure we can reach the canopy on exchange day and let us know of any changes to opening hours.
Dripping filters are a clear sign they’re full. Changing them now reduces the fuel above the cooking and the plenum may need a clean as well.
Grease filter exchange in St Nicholas, done properly
A filter service works alongside TR19® cleaning, not instead of it. Fresh filters help limit what gets into the ductwork though vapour still carries some grease past them. So the canopy, plenum and ducts still need their full TR19 clean. The work covers school and hospital kitchens, restaurants and pubs and island canopies, and people most often call us about weak extraction at the canopy and filters so greasy the air can barely pass.
Size does not change the work: a kitchen in a place like St Nicholas gets the whole system cleaned, canopy to discharge. We plan the visit around your hours, with the journey sorted in advance.
The paperwork matters as much as the work. Each visit is written up with photos, listing what was done, anything we couldn’t reach and when the next visit is due. File it in your maintenance log so it’s to hand when an insurer or inspector asks.

What we do, step by step
Your staff don’t need to do much on the day. A contact on site lets us in at the agreed time and points us to the system, and we take it from there. Afterwards, the area is left tidy and the written report follows. Everything the job in St Nicholas needs is worked out beforehand, from the survey.
- First, we check the canopies and the filters in them.
- Any damaged or missing filters are noted.
- We exchange the dirty filters for a clean set.
- We check the filters are seated and the canopy is ready to use.
- We tell you if the plenum or canopy needs a clean.
How to prepare
- Tell us where we can park and unload
- Find the previous report, if there is one
- Arrange a key holder or contact on site
Getting a quote
Quoting starts with a diagnosis, from your photos and details or, where that isn’t enough, a survey on site. After that, you get a fixed price for the work so you know the cost before we start.

What we’re called out for in St Nicholas
Wherever you are, St Nicholas included, filter washing is the job that gets skipped when the kitchen is busy. It only takes a couple of missed weeks for filters to fill with grease.
It’s time to book a visit if you see:
- Filters so greasy the air can barely pass
- Hand-washed filters that still look greasy
- Drips falling from the filters onto equipment
- Weak extraction at the canopy
If your kitchen is in a listed or historic building, like the houses around St Nicholas (Aston Bury is about 3.3 miles south), fitting access panels needs care.
Questions to ask before you book
- When the next visit should be, and why
- If the quote is a fixed price or an estimate
- Whether a written report and photos are included
- Proof of accreditation you can verify
When something else is needed
Grease filter exchange can’t fix everything, and we’ll tell you before we start. It will not put right:
- An extract that was undersized from the start
- Greasy ducts and risers that a filter change won’t reach
- A canopy that needs a proper clean
Not sure which it is? You can give us a ring on 0345 646 2711 or send us an email and we’ll tell you honestly before booking.
What the work covers
- Wall canopies
- School and hospital kitchens
- Mesh filters

Common questions in St Nicholas
Can school kitchens in St Nicholas be cleaned in the holidays?
Yes. The holidays are the usual time for school work. With about 20 schools and colleges on the FSA’s register within roughly a mile and a half of St Nicholas, it pays to plan holiday dates ahead. Send us your term dates when you call 0345 646 2711 or use the quote form, and we will fit the work in.
Can the work in St Nicholas be done at night or at weekends?
Yes. We work evenings, overnight and at weekends. It means the site in St Nicholas keeps running as normal. Let us know the hours you’re closed and we’ll book within them.
What does grease filter exchange cost?
Pricing depends on the kitchen, so we need to know the filters and interval first. You get a fixed price before the first visit.
Is filter exchange enough instead of a full extract clean?
No. Some grease passes the filters as vapour and settles in the ducts, so the full system still needs cleaning to TR19.
Who has the legal duty for fire safety?
That depends on who controls the premises. The Fire Safety Order 2005 puts the duty on the responsible person, which may be the employer, owner, landlord, facilities manager or managing agent.
Do you offer emergency callouts?
Yes. Our emergency line runs 24/7 for anything that cannot wait until a planned visit. Ring any time and tell us what’s happened.
Do you offer maintenance contracts?
Yes, of course. Send details of the systems and how they’re used, and we’ll suggest a schedule and quote for it.
What do you do with what you remove?
It’s contained and taken away. Grease, debris and waste water are collected as the work goes on rather than letting it spread.
Staff cleaning versus specialist work
Keep a record of what your team does. A simple log of filter washes, wipe-downs and checks helps show that the system is managed between specialist visits, next to our reports.
Away from the kitchen, the in-house job is mainly checking: clear grilles, a log of filter changes and reporting anything odd. Cleaning inside ducts and units is specialist work.
St Nicholas kitchens: local notes
According to Food Standards Agency records, there are about 9 pubs and bars in St Nicholas and the streets around it, up to about 1.5 miles out. A pub or hotel kitchen that cooks every day builds up grease in its extract like any other. St Nicholas sits within the area of Hertfordshire Fire and Rescue Service. Grease in a kitchen extract is a recognised fire risk, and the fire authority enforces the law on managing it in most commercial premises. Food hygiene inspections in St Nicholas are the job of Stevenage council’s environmental health team. A greasy canopy or dripping filters are the sort of thing an inspection can pick up. A TR19® certificate and photo report after each clean gives you a record to show an inspector.
A hall kitchen that only cooks for events, whether near All Saints Church or elsewhere in St Nicholas, still needs its extract cleaned, just less often. For schools such as The Leys Primary and Nursery School, kitchen extract cleaning is usually booked for the holidays, when the canteen is closed.

Managing agents and facilities teams in St Nicholas
From a single site to a large estate, the standard is the same: the system surveyed, the price fixed, the visit fitted around trading and everything written up afterwards.
Under the Regulatory Reform (Fire Safety) Order 2005, the responsible person must assess and reduce fire risk, and that can be the employer, the owner, a landlord, a facilities manager or a managing agent. Where responsibility is shared, records matter even more.
Why deal with it now?
Once filters are saturated, more grease gets past them. That makes the next full clean a bigger job, and grease may build up faster than the cleaning interval allows. A quieter site near St Nicholas still needs its system looked after.
