Canopy filter housings
We check that filters sit snugly in the housing at each visit since a gap is a route for grease.
Busy restaurant and pub kitchens
High-output kitchens clog filters quickly. They often need the shortest exchange interval.
Grease filter exchange for kitchens and businesses in Smallford
In Smallford, our filter exchange runs on a schedule set by how much the kitchen cooks. Busy kitchens need changes more often while a lighter kitchen can go longer. The interval is agreed before the first visit. Common call-outs are for missing filters in the filter bank and grease left in baffles after washing, across restaurants and pubs, baffle filters and school and hospital kitchens.
For a kitchen in or near Smallford, the visit is planned around opening hours and the journey, 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 paperwork matters as much as the work. You get a written report with photos after every visit, covering the work done, any areas we couldn’t access and a recommended next date. Keep it with your fire safety records so it’s ready for an insurer, fire officer or EHO.

What else we do in Smallford
What staff can safely do
For ventilation and air handling systems, in-house care is mostly about checks: keeping grilles clear, noting unusual noise or smells and logging filter changes. Cleaning inside ducts and units is specialist work.
Good housekeeping makes our visits easier, not unnecessary. Clean filters and tidy surfaces slow the build-up, but hidden parts of the system still need specialist attention.
When something else is needed
Before booking, it helps to know what’s not included:
- Grease behind the filters that a swap cannot remove
- Extraction problems caused by the fan rather than the filters
- Cooking smells reaching neighbours, which need odour control
If in doubt, give us a ring on 0345 646 2711 or send us an email and we’ll say what we think before you book.
Parts of the system we cover
- Mesh filters
- Wall canopies
- Island canopies
- School and hospital kitchens
- Restaurants and pubs
- Baffle filters
Smallford kitchens: local notes
Food Standards Agency records include about 12 bars, pubs and nightclubs in Smallford 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. Food hygiene inspections in Smallford are the job of St Albans City council’s environmental health team. Extraction counts as kitchen equipment, so its condition can come up on the day. A TR19® certificate and photo report after each clean gives you a record to show an inspector. Smallford is covered by 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.
Kitchens that cook twelve hours or more a day, as some healthcare kitchens do, fall into BESA’s three-monthly minimum; Hill End Hospital is the nearest hospital to Smallford, about 1.4 miles south-west. Where a hall near Church of St Mark, or anywhere in Smallford, hosts lunch clubs or events, its extract gathers grease just as a café’s does. Bursars and site managers at schools such as Nicholas Breakspear Catholic School tend to book extract cleaning for when the kitchen is empty.

Smallford: your questions answered
Can you work in Smallford outside opening hours?
Yes, out-of-hours work is a big part of what we do. That way a site in Smallford does not have to lose a day’s trading. Just ring 0345 646 2711 or drop us a line with your opening times and we’ll plan around them.
Who carries out food hygiene inspections in Smallford?
That’s St Albans City council, whose environmental health officers carry out food hygiene inspections in Smallford. Ratings are published by the Food Standards Agency, so a clean extract and good records are worth keeping up.
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 Regulatory Reform (Fire Safety) Order 2005, the responsible person has to manage fire risk, and many insurers can refuse or reduce a claim without proof of cleaning.
Does a filter exchange replace TR19 cleaning?
No. Some grease passes the filters as vapour and settles in the ducts, so the full system still needs cleaning to TR19.
Which accreditations do you hold?
CHAS, SafeContractor, ISO 9001 and BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease. We’re fully insured and have been trading since 2009.
What paperwork should we keep on file?
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 together and easy to find.
Do you cover Smallford?
Yes. Our area takes in London and the counties of South East England, and that includes Smallford.
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.
How we price grease filter exchange
The quote reflects the site in front of us. We take into account:
- Site rules, permits and inductions
- When the work can happen, such as evenings, overnight or weekends
- Travel, parking and unloading
- Whether it’s a one-off visit or part of a schedule
Several systems or sites on one quote often makes better use of the time. Mention every system or site you need covered and we’ll price it together.
What we need to know
You don’t need the technical terms. It helps if you can send:
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
- Close-ups of filters, grilles, hatches or access panels
- Wide photos of the system and the area around it
- The site address and the type of premises
Want a quote for grease filter exchange? Please call us on 0345 646 2711, or send details by email and tell us about the site. We will explain what we’d do and send a fixed quote before anything is booked.
Looking after it afterwards
Looking after the system between visits is straightforward, and it helps at the next visit:
- Wipe the outside of the canopy as part of daily cleaning
- Keep filter exchange and TR19 cleaning on the same plan
- Never cook with the extract switched off
- Make sure we can reach the canopy on exchange day
Nothing changes for your staff, except one less greasy job. Just keep the canopy clear for the next visit and let us know of any changes to opening hours.
Filter exchange and TR19 cleaning work best together. A maintenance plan that covers both keeps everything on track.
The process
There’s very little for your team to do on the day. Someone lets us in at the agreed time and shows us where everything is, and the rest is down to us. Afterwards, the area is left tidy and the written report follows. If the van will struggle with a lane or gateway near Smallford, let us know and we’ll plan around it.
- We start by noting how many filters you have and what type they are.
- Together we set how often the filters should be changed.
- Each visit starts with the used filters being removed.
- Clean filters go straight back in, seated properly with no gaps.
- If a filter is damaged or the plenum needs attention, we tell you.
Preparing for the visit
- Mention any sign-in, permit or induction we need
- Find the previous report, if there is one
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas

Landlords, agents and facilities managers
Where a tenant occupies the premises but the landlord owns the building, the lease normally sets out who maintains what. We’re happy to deal with either side and send the paperwork to whoever needs it.
For anyone managing more than one site, we can schedule visits across all of them on one quote. Each site gets its own report and pictures, so each one has its own record.
