Grease filter exchange in Appspond
Think of filter exchange as routine care for the extract. It keeps airflow up and grease down between full cleans and takes a messy task off your team. The full TR19 clean then gives the system its clean bill of health. Common call-outs are for filters left unwashed on busy weeks and smoke and heat lingering under the hood, on baffle filters, restaurants and pubs and island canopies.
In a small place like Appspond, kitchens are often in older or extended buildings, with long single-storey duct runs, and those horizontal sections are where grease settles. Access, parking and timings are agreed before the day.
Our accreditations include CHAS, SafeContractor and ISO 9001, and we’re fully insured. We are also a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, trading since 2009.

The process
Protection comes first: floors, worktops and anything near the work are covered. Then we make the system safe and start. The work on site takes well under an hour for most canopies, and the area is cleaned down before we leave. Photos of the system and how to reach it help us plan a visit to Appspond.
- We count and measure the filters in every canopy.
- We agree a schedule that suits how much the kitchen cooks.
- On each visit, the dirty filters come out of the canopy.
- We fit clean filters and check they sit snugly in the housing.
- If a filter is damaged or the plenum needs attention, we tell you.
Getting ready for the visit
- Have your last certificate or report to hand
- Clear loose items from the work area
- Make sure someone can let us in and lock up afterwards
Ask for a quote
We do not publish a price list, because no two systems are the same. Instead, we look at your site first, from photos or a survey, then send a fixed quote. To start, call 0345 646 2711 or drop us a line.
Related advice
Leave it or put it right?
Some kitchens in Appspond wash filters themselves to save the cost of a service, and that can work if it’s done thoroughly and on time. Where it slips, an exchange service takes the job off staff. Systems in rural buildings are often out of sight and out of mind.
Whatever the type of site, the quote works the same way: the size of the job, access, condition and working hours. Call for a fixed quote and we will explain each part.
Why us?
- Ventilation hygiene specialists since 2009
- CHAS and SafeContractor accredited, with ISO 9001

What affects the quote in Appspond
The diagnosis comes before the price. The main factors are:
- The size of the system
- The condition we find in the survey
- Site requirements such as sign-in and permits
- Whether it’s a one-off visit or part of a schedule
No two sites are the same, so we price each one individually. The size of the job, how we reach it, its condition and the working hours all play a part.
What we need to know
We can often survey from photos. The most useful are:
- Photos showing the whole system and its surroundings
- The postcode and the type of business
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
- How we’d reach plant on a roof or in a plant room
Photos are the quickest way to a quote: wide shots of the system, close-ups of anything that worries you and how we’d get to it. Tell us what kind of site it is and when it’s open, and we can price many jobs without a visit.
Between visits
How long the results last depends on use and care. Here’s what we suggest:
- Book full TR19 cleans alongside filter changes
- Clear anything stored on or near the canopy
- Mention it if the kitchen gets busier
- Keep the extract on whenever the range is in use
Your team carries on as normal, without the filter washing. Make sure we can reach the canopy on exchange day and let us know of any changes to opening hours.
Damaged filters leave gaps in the defence. Replacing them early protects the plenum and ductwork.
Kitchen extracts in Appspond
The Food Standards Agency lists about 5 bars, pubs and nightclubs as registered food businesses in Appspond 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. The fire and rescue service for Appspond is 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. Environmental health officers from St Albans City council inspect food businesses in Appspond. 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.
Healthcare kitchens, like those at hospitals such as Leavesden Hospital (about 2.5 miles south), often cook for long hours, which puts them in BESA’s heavier-use bands. If your kitchen is in a listed or historic building, like the houses around Appspond (High Elms Manor is about 2.5 miles south), fitting access panels needs care. If you look after a school kitchen, at a school such as Marlborough Science Academy or anywhere near Appspond, the holidays are the usual time for a TR19® clean.

How the job changes from site to site
Baffle filters
Baffle filters use overlapping metal blades that force the air to change direction. Grease drops out as it does.
Busy restaurant and pub kitchens
In a busy kitchen, filter washing is easy to skip. An exchange service takes it off the rota.
Common questions in Appspond
Who carries out food hygiene inspections in Appspond?
Food hygiene inspections in Appspond 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.
Do you work at weekends in Appspond?
Yes, we can come after you close and finish before you open. The work in Appspond can fit around your hours. Your opening times are the first thing we ask for.
Who is responsible for fire safety on the premises?
The law calls them the responsible person. That’s generally the employer or the person in control of the premises, and where several people have control, each can have duties. Your lease and fire risk assessment should make it clear.
What’s the right interval for changing filters?
It varies with the type and amount of cooking. If filters clog early, the interval needs shortening and we will adjust it.
Do you survey before quoting?
Yes, every time. We diagnose before we treat: the survey shows what needs doing and what access we need, and the quote is based on that.
Do you provide a certificate or report?
Yes, always. The report is dated and includes pictures, and TR19® Grease cleans come with a certificate through the BESCA VHE portal. Keep it in your maintenance log.
Do you have insurance?
Yes. We carry full insurance and have been trading since 2009.
What happens to the waste?
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
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.
For ventilation and air handling systems, in-house care is mostly about checks: clear grilles, a log of filter changes and reporting anything odd. Cleaning inside ducts and units is specialist work.

For landlords and multi-site operators
When the building owner and the occupier are different, it’s worth checking the lease for who maintains the systems. We’re happy to deal with either side, and the report can go to both.
Records are where multi-site compliance often slips. Each visit ends with a dated report and pictures, ready to show insurers, fire officers or EHOs.
