Landlords, agents and facilities managers
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. With shared responsibility, good records help everyone.
We also work for facilities teams across offices, schools and healthcare across Hertfordshire. Larger estates can be phased building by building around the people who use them.
Grease filter exchange in Blackmore End, done properly
Across Blackmore End, our filter exchange suits restaurants, pubs, cafés, schools, care homes and other kitchens, whether there’s one canopy or many. We can come before or after service, so cooking is not interrupted. We’re often asked to deal with weak extraction at the canopy and a canopy that drips grease, across island canopies, restaurants and pubs and mesh filters.
Rural kitchens often have long, low duct runs through a roof space or along an outside wall, where grease settles in the flat sections. We agree access and timings in advance.
Our accreditations include CHAS, SafeContractor and ISO 9001, and we’re fully insured. We’re also a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we’ve been trading since 2009.

Keeping the system healthy
Once we’ve finished, these simple steps help:
- Look out for drips from the canopy
- Always run the extract while cooking
- Book full TR19 cleans alongside filter changes
- Let us know if your cooking hours increase
We tell you if we spot anything in the canopy that needs attention. That might mean bringing a TR19® clean forward, and we can arrange it.
Filter exchange and TR19 cleaning work best together. A maintenance plan that covers both keeps everything on track.
Fixed quotes for grease filter exchange in Blackmore End
We quote each job individually. These are the things that affect it:
- Travel, parking and unloading
- The times the site is available
- Site requirements such as sign-in and permits
- Access, including roofs, risers and ceiling voids
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.
Helping us quote
A few details help us quote accurately. With your enquiry, please include:
- Any symptoms, from odd noises to smells or leaks
- Detail shots of panels, filters and grilles
- Wide pictures of the system and the area around it
- The times we could work without disrupting the site
We don’t publish a price list, because no two systems are the same. Instead, we look at your site first, from photos or a survey, and then give you a fixed quote. To start, call us on 0345 646 2711, or email photos.

Blackmore End questions
Who enforces fire safety at workplaces in Blackmore End?
Blackmore End is in the area of Hertfordshire Fire and Rescue Service. Records of extract cleaning are a sensible thing to have ready if a fire safety officer carries out an audit.
Do you cover smaller places like Blackmore End?
Yes, Blackmore End is part of our area, however small the site. Let us know about access, parking and anything unusual about getting there when you book.
What does TR19 mean?
TR19® is the BESA specification for keeping ventilation systems clean. Since 2019, TR19® Grease has been a standalone specification for grease in kitchen extract systems, while TR19® Air covers other supply and extract ductwork.
Do you survey before quoting?
Yes. For many sites, photos and a few details are enough, while bigger or harder-to-see systems are surveyed on site.
Are you accredited?
Our accreditations are CHAS, SafeContractor and ISO 9001, and we are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. The Vent Hygiene Elite scheme is run by BESCA and audited independently.
How much notice should we give?
For planned work, earlier is better, especially if the next clean or test is due soon. For emergencies, we take calls 24/7.
Can you look after several sites?
Yes. One number covers all your sites in our area, with visits on a regular schedule.
Do you clean filters as well as exchanging them?
Yes, filter cleaning is available. We will check your filters first, as damaged ones may be better replaced.
Grease, kitchens and Blackmore End
Look up Blackmore End on the FSA’s food hygiene register and you will find about 4 restaurants, cafés and works canteens within roughly a mile and a half of the centre of Blackmore End. Each canopy among them has filters that load with grease and need swapping or cleaning. Hertfordshire Fire and Rescue Service covers Blackmore End. Its fire safety officers can audit commercial kitchens, and grease in the extract is part of a kitchen’s fire risk. It’s St Albans City council that sends environmental health officers to food businesses in Blackmore End. An officer looking round a kitchen will see the canopy, and grease there is hard to miss. A TR19® certificate and photo report after each clean gives you a record to show an inspector.
If you run catering at a healthcare site, such as a hospital like St Albans City Hospital about 5.6 miles south, the extract may need cleaning more often than a part-time kitchen. If you look after a school kitchen, at a school such as Kimpton Primary School or anywhere near Blackmore End, the holidays are the usual time for a TR19® clean. If you run a church or community hall kitchen, near St Peter or elsewhere in Blackmore End, its extract still collects grease from every lunch and event.

Leave it or put it right?
Filters full of grease are fuel sitting right above the cooking. Flames from the range can be drawn up into the canopy and grease in the duct can carry a fire further. Keeping filters clean takes some of that fuel away. In a small place like Blackmore End, a system that fails can take a site out of use.
We do not list prices on the website, because the cost depends on the site in front of us. Call for a fixed quote, and we will explain what it covers.

What a clean will not put right
We’d rather tell you now than book work that won’t help, so these are the things it will not cover:
- A canopy too small for the cooking beneath it
- A noisy or failed extract fan
- Greasy ducts and risers that a filter change won’t reach
If you’re not sure, just ring 0345 646 2711 or email us and we will give you a straight answer.

How it works
There’s very little for your team to do on the day. A contact on site lets us in at the agreed time and points us to the system, and the rest is down to us. Before we leave, the area is tidied and the paperwork follows. If you can send pictures, we can arrive in Blackmore End knowing what to expect.
- We count and measure the filters in every canopy.
- Together we set how often the filters should be changed.
- On each visit, the dirty filters come out of the canopy.
- Clean, dry filters are fitted in their place, with no gaps left between them.
- We flag any damaged filters or anything wrong with the canopy.
Getting ready for the visit
- Tell us about site rules, permits or sign-in
- Agree a time when the area can be out of use
- Dig out any earlier paperwork for the system
