Grease filter exchange for kitchens and businesses in Rooks Nest
Each visit is quick and tidy. We lift out the dirty filters and fit a clean set, and we check they’re seated with no gaps. Anything that needs attention is pointed out. The work covers baffle filters, restaurants and pubs and wall canopies, and the jobs we see most are bent or damaged filters that don’t sit properly and grease building up behind the canopy filters.
For a kitchen in or near Rooks Nest, the visit is planned around opening hours and the journey, and the clean covers the whole system, as it would anywhere: canopy, filters, duct, fan and discharge, with a certificate and photo report at the end.
Each visit ends with a written report and photos, so you have a record of what was done and when. Kitchen extract cleaning to TR19® Grease is certificated through the BESCA Vent Hygiene Elite portal.

How we price grease filter exchange
The quote reflects the site in front of us. We take into account:
- Whether it’s a one-off visit or part of a schedule
- What state the system is in
- Travel, parking and unloading
- The size of the system
What you pay reflects the actual work. That’s why we survey first, from pictures or on site, and why the quote is fixed before we start.
Asking for a quote
When you call or email, it’s useful to have:
- Any previous report or certificate
- How we’d reach plant on a roof or in a plant room
- Any symptoms, from odd noises to smells or leaks
- When the site is open and when it’s quiet

Common problems we fix in Rooks Nest
Hand-washed filters often come back still greasy. Grease lodges deep in baffles and mesh and a sink wash rarely reaches it.
Clients usually contact us when they notice something like this:
- Filters left unwashed on busy weeks
- Damaged filters letting grease past
- Poor airflow through the filters
- Gaps where filters have been removed
Term dates shape school work: for a school like Trotts Hill Primary and Nursery School, an extract clean fits neatly into a half-term or summer break.
What to look for in a quote
- Whether the figure could change on the day
- Whether VAT is included
- Whether a survey comes first
- Proof of accreditation you can verify
Looking after it afterwards
A little care between visits keeps the system in better shape. Our advice:
- Never cook with the extract switched off
- Report a dripping canopy early
- Do not refit a filter that’s bent
- Clear anything stored on or near the canopy
The next exchange is already in the diary. If cooking increases, we can change filters more often to keep up.
Filters that are left too long stop protecting the system. A regular cycle keeps the rest of the system cleaner until the next TR19 clean.
Multi-site and managed buildings
Keeping records across a portfolio is half the battle. Each visit ends with a dated report and photos, so you can show an insurer or inspector what was done at each site.
Under the Regulatory Reform (Fire Safety) Order 2005, the responsible person must assess and reduce fire risk, which may be the employer, owner, landlord, FM or managing agent. Where responsibility is shared, records matter even more.
What staff can safely do
Day-to-day cleaning is something your team can do: wiping canopies, washing grease filters and recording it in a log. Inside the ducts, risers and fan is specialist work, and that is where we come in.
Good housekeeping makes our visits easier, not unnecessary. Regular in-house cleaning slows the build-up, but the parts you can’t see still need a specialist at the right interval.

Why it’s worth doing now in Rooks Nest
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. Clean filters mean less fuel in the canopy. If the system at a site near Rooks Nest fails, there may be nowhere nearby to move to.
When the work has to happen, how we reach it and how big the site is can all change the price. We take each of them into account and give you a fixed price before we start.

Kitchen extracts in Rooks Nest
Food Standards Agency records include about 23 pubs and bars across Rooks Nest and its immediate surroundings (about a mile and a half). Where they serve hot food, their kitchen extracts need cleaning to TR19® like any restaurant’s. It’s Stevenage council that sends environmental health officers to food businesses in Rooks Nest. They look at how clean the premises and equipment are, and the kitchen extract is part of that. Keeping each certificate and photo report on file helps show the extract is looked after. Rooks Nest is covered by Hertfordshire Fire and Rescue Service. Fire and rescue authorities enforce the Fire Safety Order in most non-domestic premises, and in a kitchen that fire risk includes the grease in the extract.

Your questions about grease filter exchange in Rooks Nest
Do you work overnight in Rooks Nest?
Yes. We work evenings, overnight and at weekends. It means the site in Rooks Nest keeps running as normal. Your opening times are the first thing we ask for.
Can school kitchens in Rooks Nest be cleaned in the holidays?
Yes, holiday work suits schools best. The FSA’s register shows about 23 schools and colleges with food registrations within roughly a mile and a half of Rooks Nest. Send us your term dates when you give us a ring on 0345 646 2711 or send us an email, and we will fit the work in.
Do you recommend a next date?
Yes. Every report includes a recommended date for the next visit, based on use and what we found.
What happens to the dirty filters?
The greasy set leaves with us for cleaning, so your staff don’t have to wash them. Clean filters go straight in.
What is TR19?
It’s the industry benchmark for cleaning ventilation and kitchen extract systems, written by BESA. It sets out inspection, cleaning and record keeping, and it takes a risk-based approach.
What about areas you cannot get to?
The report shows them clearly. In ductwork, new access panels are often the answer, and we can fit those.
Can we skip TR19 cleans if the filters are changed regularly?
No, the two work together. TR19® cleaning covers the canopy, plenum, ductwork and fan, with a certificate and photo report.
How much does a filter exchange service cost?
It depends on the number and type of filters and how often they’re changed. Just ring 0345 646 2711 or send us an email for a fixed quote once we know your canopies.
The process
Everything the job needs comes with us, from protective sheeting to tools and access equipment. You only need to give us clear access and switch off what needs to be off. On site, the work takes a short visit, depending on how many filters the canopies hold. If you can send pictures, we can arrive in Rooks Nest knowing what to expect.
- 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.
- We check the filters are seated and the canopy is ready to use.
- We tell you if the plenum or canopy needs a clean.
Getting ready for the visit
- Make sure equipment near the work can be switched off and left to cool
- Arrange a key holder or contact on site
- Let us know about parking and loading
