Send us your term dates when you give us a ring on 0345 646 2711 or send us an email, and we’ll fit the work in.
Who enforces fire safety at workplaces in North Watford?
That’s 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 grease filters does the service cover?
We exchange baffle and mesh filters. We record the sizes and number of filters at the start so every set we bring fits.
How long does grease filter exchange take?
That depends on how much there is to do, but for many sites it takes anything from a few minutes to an hour or so, depending on the number of filters. We’ll confirm it with the quote.
What happens to the waste?
It leaves the site with us when we go. During the work, it’s contained to keep the area clean.
What accreditations do you have?
BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease, plus CHAS, SafeContractor and ISO 9001. We have been trading since 2009 and we’re fully insured.
Can you come out in an emergency?
Yes, day and night, every day of the year. Our office is open from 8am to 6pm on weekdays, with the emergency line covering every other hour.
What do you do to protect the area?
With sheeting and covers, before anything else happens. We keep the work contained and leave the area clean.
Grease filter exchange in North Watford
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. Typical jobs include grease dripping from the canopy and filter washing that keeps being missed, on wall canopies, island canopies and restaurants and pubs.
Around a smaller place like North Watford, kitchen extracts tend to belong to pubs, cafés, takeaways and school or care home kitchens. A kitchen that cooks fewer hours still builds up grease, so the interval is set by hours of use and grease readings.
Good records are part of the job. Each visit is written up with pictures, covering the work done, any areas we couldn’t access and a recommended next date. File it in your maintenance log so it’s to hand when an insurer or inspector asks.

Grease filter exchange in North Watford: the local picture
Food Standards Agency records include about 35 pubs, bars and clubs and about 7 hotels, B&Bs and guest houses in and around North Watford, up to about a mile and a half out. Wherever they cook, the canopy, duct and fan collect grease just as a restaurant’s do. The fire and rescue service for North Watford 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. Kitchens in North Watford get their food hygiene inspections from Watford council. A greasy canopy or dripping filters are the sort of thing an inspection can pick up. A dated certificate in the maintenance file answers the question before it’s asked.
Term dates shape school work: for a school like Knutsford Primary Academy, an extract clean fits neatly into a half-term or summer break. Kitchens that cook twelve hours or more a day, as some healthcare kitchens do, fall into BESA’s three-monthly minimum; Watford General Hospital is the nearest hospital to North Watford, about 1.8 miles south.

What the work involves, part by part
Baffle filters
In a baffle filter, the air zigzags through metal baffles. Grease drops out as it does.
School, care home and staff kitchens
For kitchens closed in the holidays, visits can be timed around term or rota, keeping the filters ready for the busy weeks.
What affects the quote in North Watford
Before we fix a price, we need to know a few things. We look at:
- Whether several sites go on one quote
- One-off work versus a regular cycle
- When the work can happen, such as evenings, overnight or weekends
- Where the site is and how we reach it
Working hours, access and the scale of the site can all change the price. We take each of them into account and give you a fixed price before work begins.
Asking for a quote
To help us quote quickly, send us:
- Your opening hours and when the area is out of use
- A few general shots of the system
- How we’d reach plant on a roof or in a plant room
- The postcode and the type of business
There’s no standard price list, because no two systems are the same. We look at your system first, from photos or on a visit, then send a fixed quote. To start, give us a ring on 0345 646 2711 or send us an email.
Keeping the system healthy
No system stays clean for ever, but care slows the build-up. A few tips:
- Never cook with the extract switched off
- Clean the canopy surfaces regularly
- Book full TR19 cleans alongside filter changes
- Tell us if a filter is bent or damaged
If the plenum behind the filters looks greasy, we say so. That might mean bringing a TR19® clean forward and we can book that in.
Dripping filters are a clear sign they’re full. A clean set straight away cuts the grease in the canopy and the plenum may need a clean as well.
What happens on the day
Your staff do not need to do much on the day. Someone lets us in at the agreed time and shows us where everything is, and we take it from there. Before we leave, the area is tidied and the paperwork follows. Around North Watford, access is usually simpler than in a town centre, though gates and roof access are worth mentioning.
- 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.
- The filters are checked for fit before we go.
- Anything that needs attention, such as a greasy plenum, is pointed out.
Before we arrive
- Let us know when the site is closed or quiet
- Let us know about permits to work or site inductions
- Dig out any earlier paperwork for the system

Related advice
Do you need grease filter exchange in North Watford?
However long the kitchen cooks each day, the filters see every minute of it. Heavy daily use means fast build-up so changes need to come round sooner.
If you notice any of these, it’s worth a diagnosis:
- Grease building up behind the canopy filters
- A canopy running with filters missing
- Weak extraction at the canopy
- Filters that leave gaps in the canopy
Church and community hall kitchens, near St Peter's Church or anywhere around North Watford, are easy to forget, but their extracts collect grease like any other.
What to look for in a quote
- What paperwork you get at the end
- Whether the quote is based on a survey or photos
- Their accreditations, such as BESCA Vent Hygiene Elite, CHAS or SafeContractor
- If the quote is a fixed price or an estimate
What staff can safely do
Staff cleaning and specialist work aren’t the same thing. Wiping filters daily and washing them weekly keeps the visible parts in order, but they do not reach the grease that builds up further in. Reaching it takes a specialist with the right equipment.
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.
