What grease filter exchange looks like in Harpenden
According to Food Standards Agency records, there are about 23 pubs and bars in Harpenden and the streets around it, up to about 1.5 miles out. Wherever they cook, the canopy, duct and fan collect grease just as a restaurant’s do. In Harpenden, food businesses are inspected by environmental health officers from St Albans City council. An officer looking round a kitchen will see the canopy, and grease there is hard to miss. Before-and-after photos from each clean are a simple way to show the extract is in hand. Harpenden sits within the area of Hertfordshire Fire and Rescue Service. Its fire safety officers can audit commercial kitchens, and grease in the extract is part of a kitchen’s fire risk.
A hospital like St Albans City Hospital, about 3.9 miles south, is the kind of site where a kitchen may cook for patients, staff and visitors all day. If you run a church or community hall kitchen, near St Nicholas Church or elsewhere in Harpenden, its extract still collects grease from every lunch and event. For kitchens close to Harpenden station, where the day often starts early and ends late, the extract can be cleaned overnight.

Grease filter exchange in Harpenden
Across Harpenden, our filter exchange suits restaurants, pubs, cafés, schools, care homes and other kitchens, from a single canopy to several. Visits can be timed around your service so nobody has to stop cooking. Typical jobs include gaps where filters have been removed and filters that leave gaps in the canopy, across mesh filters, baffle filters and island canopies.
Most kitchens in a town like Harpenden can’t close for a day, so the work is done after service, overnight or on a closed day. The kitchen is handed back clean and ready to cook.

How the visit works
Your staff do not 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. Sites in a town like Harpenden rarely need to lose trading hours, as the work fits around them.
- First, we record the size, type and number of filters in each canopy.
- A change schedule is agreed to match the kitchen’s cooking hours.
- At each visit, the greasy filters are lifted out.
- We fit clean filters and check they sit snugly in the housing.
- We flag any damaged filters or anything wrong with the canopy.
Preparing for the visit
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
- Move anything stored near the system
- Have your last certificate or report to hand
Getting a quote
Quoting starts with a diagnosis, either from pictures and details you send or from a site visit. Then we send a fixed price so you know the cost before work begins.

Managing agents and facilities teams in Harpenden
Multi-site operators often want one contractor and one number. We cover South East England and London, so visits at different addresses can be planned together and kept to a regular schedule.
Where a tenant occupies the premises but the landlord owns the building, the lease normally sets out who maintains what. We can quote either party, and the report can go to both.
What happens if it’s left?
Grease-loaded filters are a fire risk in their own right. Flames from the range can be drawn up into the canopy, and from there into the duct. Keeping filters clean takes some of that fuel away. Catching it early in Harpenden means you choose the day.
Leaving it longer rarely makes the work cheaper. Problems in a system tend to grow, and a neglected system can mean more work. If you are not sure what’s needed, phone us on 0345 646 2711 or email us and we will give you an honest view and a fixed quote.

What your team can do, and what needs us
Good housekeeping makes our visits easier, not unnecessary. Regular in-house cleaning slows the build-up, but hidden parts of the system still need specialist attention.
Keep a record of what your team does. A dated log of in-house cleaning and checks helps show that the system is managed between specialist visits, alongside our reports.
Questions from Harpenden
Which fire and rescue service is responsible for Harpenden?
Harpenden is in the area of Hertfordshire Fire and Rescue Service. A recent cleaning certificate and a note of the next clean date show that grease in the extract is being managed.
Which environmental health team covers Harpenden?
Food hygiene inspections in Harpenden are carried out by St Albans City council. Ratings are published by the Food Standards Agency, so a clean extract and good records are worth keeping up.
Where do the greasy filters go?
We do. Used filters go with us to be cleaned and the clean set stays in the canopy.
Can damaged filters stay in the canopy?
Each filter is looked at when we exchange. We tell you about any that are damaged since a poor fit lets grease past.
Can you look after several sites?
Yes. Tell us the addresses and what each needs and we’ll quote them together.
What should go in our maintenance log?
The reports and certificates from each visit, plus your own logs. They’re what an insurer, fire officer or EHO may ask for, so keep them where they can be found quickly.
Do I get a report after the visit?
Yes. Every visit ends with a written report and pictures, showing what was done, anything we couldn’t reach and when the next visit is due. Kitchen extract cleans to TR19® Grease also get a certificate through the BESCA Vent Hygiene Elite portal.
How long does the visit take?
It depends on the size of the system, but for many sites it takes less than an hour in most kitchens. We will confirm it with the quote.

How the job changes from site to site
Canopy filter housings
The filter housing holds each filter at an angle in the canopy. A damaged housing leaves gaps.
Mesh filters
Mesh traps grease between its layers, so a quick rinse rarely gets it clean.
What affects the cost of grease filter exchange
The survey tells us what the work involves. The main factors are:
- Whether it’s a one-off visit or part of a schedule
- The number of sites or systems
- What state the system is in
- The size of the system
Whatever the type of site, the quote works the same way: the size of the job, access, condition and working hours. Ask for a fixed quote and we will go through it with you.
What we need to know
Photos let us diagnose from a distance. The most useful are:
- Detail shots of panels, filters and grilles
- How we’d reach plant on a roof or in a plant room
- The times we could work without disrupting the site
- Your last certificate, test record or report
There’s no standard price list, because no two systems are the same. We look at your system first, from pictures or on a visit, then send a fixed quote. To get going, ring 0345 646 2711 or email us.
Honest limits
Grease filter exchange can’t fix everything, and we’d rather say so up front. It does not solve:
- Odours from the discharge that filters will not stop
- An extract that was undersized from the start
- Grease behind the filters that a swap cannot remove
If in doubt, ring 0345 646 2711, or send details by email and we’ll say what we think.
