Harrow: your questions answered
Who is the fire and rescue service for Harrow?
London Fire Brigade is the fire and rescue service for Harrow. It’s worth keeping your fire risk assessment, TR19® certificates and photo reports together, ready to show.
Can school kitchens in Harrow be cleaned in the holidays?
Yes, holiday work suits schools best. With about 10 schools and colleges on the FSA’s register within roughly a mile and a half of Harrow, it pays to plan holiday dates ahead. You can call 0345 646 2711 or drop us a line with the dates the site is empty.
Do you recommend a next date?
Yes. Every report includes a recommended date for the next visit, based on what we found and how the system is used.
Do I get a report after the visit?
Yes. Every visit ends with a written report and pictures, showing what was done, anything we couldn’t reach and when the next visit is due. Kitchen extract cleans to TR19® Grease also get a certificate through the BESCA Vent Hygiene Elite portal.
How much notice do you need?
Earlier is better, particularly for night and weekend visits. We typically quote within one working day, and emergencies are covered by our 24/7 line.
Is there a survey before the work?
Yes. We always survey first, either from photos and details you send or on a site visit. A fixed quote follows.
How often should grease filters be changed?
It varies with the type and amount of cooking. If filters clog early, the interval needs shortening and we’ll adjust it.
How much does a filter exchange service cost?
Filters, canopies and how often you need visits all affect the price. Send us details or pictures and we’ll quote quickly.
About our grease filter exchange in Harrow
A filter that does not sit right lets grease straight past. Bent, damaged or missing filters leave gaps and every filter is checked when we swap them. Damaged filters are flagged so they can be replaced. Common call-outs are for a greasy plenum behind the filters and grease left in baffles after washing, across mesh filters, school and hospital kitchens and baffle filters.
In London, few kitchens can spare a day to close, so extract cleaning in Harrow is usually done overnight, after the last service. Parking, loading and access to the roof are agreed with the building before the night of the clean.
Insurers, fire officers and environmental health officers all look at records. That is why every job is written up in a report with photos, and grease extract cleans come with a TR19® certificate issued through the BESCA Vent Hygiene Elite portal.

Grease filter exchange in Harrow: the local picture
The FSA’s food hygiene register includes about 26 bars, pubs and nightclubs and about 3 hotels, B&Bs and guest houses within about 1.5 miles of central Harrow. Wherever they cook, the canopy, duct and fan collect grease just as a restaurant’s do. Environmental health officers from Harrow council inspect food businesses in Harrow. A greasy canopy or dripping filters are the sort of thing an inspection can pick up. Before-and-after photos from each clean are a simple way to show the extract is in hand. Harrow sits within the area of London Fire Brigade. In most workplaces, including commercial kitchens, it’s the fire and rescue authority that enforces the Fire Safety Order.
If you run catering at a healthcare site, such as a hospital like Clementine Churchill Hospital about 1 mile south-east, the extract may need cleaning more often than a part-time kitchen. If you run a café or takeaway near Harrow-on-the-Hill station, early starts and late finishes leave little time to clean, so overnight extract cleaning suits.

What staff can safely do
Keep a record of what your team does. A dated log of in-house cleaning and checks helps show that the system is managed between specialist visits, next to our reports.
When your team notices a problem between visits, like drips, unusual noise, smells or damaged filters, it’s best reported rather than tackled in-house. We will take a look and give you a fixed quote.
How the job changes from site to site
School, care home and staff kitchens
Kitchens that cook for set mealtimes still load their filters though usually at a gentler pace.
The plenum
Behind the filters sits the plenum, where air gathers before the duct. Grease that gets past the filters settles there.
The process
Our technicians bring everything the work needs, from protective sheeting to tools and access equipment. You only need to give us clear access and switch off what needs to be off. The visit takes a few minutes per canopy, longer for a large kitchen with several canopies. Before any visit in Harrow, we agree where the van can stop and how equipment reaches the system.
- First, we record the size, type and number of filters in each canopy.
- A change schedule is agreed to match the kitchen’s cooking hours.
- 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.
- Anything we notice, such as bent filters or a dirty plenum, is pointed out.
Getting ready for the visit
- Agree a time when the area can be out of use
- Dig out any earlier paperwork for the system
- Let us know how we reach the system, including roofs, risers and plant rooms
How to get a quote
Some systems can be priced from pictures; others need a survey. Larger sites, and anything hidden behind walls, ceilings or floors, are normally surveyed first. Either way, the quote is fixed before any work is booked.

Managing agents and facilities teams in Harrow
Facilities teams in offices, schools and healthcare sites book us too across Greater London. Larger estates can be phased building by building to keep disruption down.
Managing agents often deal with us directly. Send the address, what’s needed and how access works, and we will send a fixed quote.
Leave it or put it right?
When filters block, extraction suffers. The kitchen gets hotter and smokier while the fan strains. A regular exchange keeps the airflow where it should be. A building in Harrow may have flats or offices above and alongside, and a fault in the system can affect them too.
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 any work starts.

Aftercare tips
How long the results last depends on use and care. We suggest:
- Never cook with the extract switched off
- Keep canopy surfaces wiped down
- Watch for grease drips between visits
- Let us know if your cooking hours increase
We tell you if we spot anything in the canopy that needs attention. It can be a sign that a full TR19® clean is due, and we can arrange it.
Filter exchange and TR19 cleaning work best together. Setting both up on a schedule keeps everything on track.
What we’re called out for in Harrow
Kitchens in Harrow, as everywhere, find filter washing slips down the list on busy weeks. It only takes a couple of missed weeks for filters to fill with grease.
If you notice any of these, it’s worth a diagnosis:
- A greasy plenum behind the filters
- A canopy running with filters missing
- A canopy that drips grease
- Filters that leave gaps in the canopy
Volunteers running a hall kitchen near Church of St Peter, or anywhere in Harrow, may not know when the extract was last cleaned, and a grease test settles it.
