Kitchen extract cleaning in Blackwater, Hampshire
We cover Blackwater for TR19 Grease cleaning of complete kitchen extract systems, from canopy to discharge. Fixed quotes, work around your opening hours and photo reports on every job.
- An overdue clean flagged by an EHO or fire officer
- Years of baked-on grease in the ducts
- Poor airflow at the canopy
What happens on the day
We turn up at the time agreed with you, often in the evening, overnight or at the weekend so the site keeps working. Anything that needs to be off for the work is switched off and left to cool first, and floors and nearby surfaces are sheeted. The work itself takes a single shift for most kitchens, with long duct runs and tall risers needing more time. Tell us when your site near Blackwater is quiet and the visit will be booked for then.
- You send pictures or we visit, and the system is surveyed from canopy to discharge.
- We take grease readings at set points and send you a fixed quote.
- On the night, the equipment is off and cool and the kitchen is sheeted.
- We work through the system from the canopy to the fan and discharge.
- Readings are repeated, photos taken, and your TR19 certificate and photo report issued.
How to prepare
- Make sure equipment near the work can be switched off and left to cool
- Mention any parking or loading restrictions
- Arrange a key holder or contact on site
How to get a quote
For a fixed quote, call 0345 646 2711, or email photos and tell us the type of site, your opening hours and roughly what the system looks like. Photos and the last report, if you have one, make the quote quicker. We typically come back within one working day.

About our kitchen extract cleaning in Blackwater
Few kitchens can stop cooking for a day so the extract can be cleaned. Cleans are booked for evenings, overnight or weekends, or during holidays where a site closes for them. With the equipment off and cool and the area sheeted, we clean and hand the kitchen back ready for the next service. If you’re dealing with a new tenancy or takeover with no cleaning history and years of baked-on grease in the ducts, we can put it right. Canopy cleaning, extract cleaning and duct cleaning are often used to mean the same thing, but in Blackwater, as everywhere, the insurer wants the full system cleaned, not just the hood.
Kitchens that fry and grill hardest need the most frequent cleans, so we look at the menu as well as the opening hours when we suggest the next date.
Size does not change the work: a kitchen in a place like Blackwater gets the whole system cleaned, canopy to discharge. The visit is booked around your opening hours, and the journey is planned ahead.
The paperwork matters as much as the work. Each visit is written up with photos, listing what was done, anything we couldn’t reach and when the next visit is due. File it in your maintenance log so it’s ready for an insurer, fire officer or EHO.

Landlords, agents and facilities managers
We work for landlords, managing agents and facilities managers as well as the people running the site. Shared systems, like a riser serving several units, need a clear agreement on who books the work, and we can quote for the whole system.
When the building owner and the occupier are different, the lease normally sets out who maintains what. We are happy to deal with either side and send the paperwork to whoever needs it.
Different parts, different methods
Schools, hospitals and care homes
Even a kitchen that cooks only a few hours a day needs cleaning at least every 12 months under BESA guidance. Holidays make it simple to schedule.
Restaurant and pub kitchens
Losing a service isn’t an option for most restaurants and pubs. We work overnight and at weekends where that suits, and hand back a clean kitchen ready to cook.
Kitchen extracts in Blackwater
Look up Blackwater on the FSA’s food hygiene register and you will find about 37 restaurants, cafés and works canteens and about 31 takeaways in Blackwater and the streets around it, up to about 1.5 miles out. Any of them cooking under a canopy is sending grease into its ductwork every service. Blackwater is covered by Hampshire and Isle of Wight 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. In Blackwater, food businesses are inspected by environmental health officers from Hart 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.
If you run a church or community hall kitchen, near St Barnabas Church or elsewhere in Blackwater, its extract still collects grease from every lunch and event. A kitchen near Blackwater station that serves breakfast and dinner can run its extract twelve hours or more, which shortens the cleaning interval.

Blackwater questions
Is Blackwater within the area you cover?
Yes, we work in villages as well as towns, and Blackwater is covered. The journey is planned ahead, so a few details about the route help.
Do you do school kitchen extract cleaning in Blackwater in the summer holidays?
Yes, and it’s the easiest time to do it. There are about 7 schools, colleges and universities on the FSA’s food hygiene register within about 1.5 miles of Blackwater. Booking early in the term gives the best choice of holiday dates.
Do you have a 24/7 line?
Yes, day and night, every day of the year. Office hours are Monday to Friday, 8am to 6pm, with the emergency line covering every other hour.
What happens if you cannot reach some of it?
We never leave them off the paperwork. The report says which parts couldn’t be reached and why, and we can quote to improve the access.
What should I send you?
A short description and a few pictures, with the address and opening hours. If we need more, we’ll ask.
How often should a kitchen extract be cleaned?
Under BESA guidance, the minimum depends on how long you cook each day: every 3 months for 12 to 16 hours, 6 months for 6 to 12 hours and 12 months for 2 to 6 hours. Measured grease levels set the real interval.
Can you quote from pictures?
Yes, for many jobs. Send a few wide pictures plus close-ups of panels, filters or grilles, and a fixed quote normally follows within one working day. Some sites still need a visit, and we’ll say so.
Do insurers need proof of extract cleaning?
Extract grease is fuel for a kitchen fire, which is why many insurers require TR19 cleaning. Our certificate and photo report give you that evidence.
When to call us in Blackwater
Grease in an extract starts as vapour. As the air cools on its way through the duct, the fat condenses and sticks, and the layer grows a little with every meal cooked. Filters catch some of it, but never all.
If you notice any of these, it’s worth a diagnosis:
- Poor airflow at the canopy
- Fat running down the canopy edge
- Heavy grease build-up inside the duct runs
- A kitchen taken over without any extract records
For schools such as Frogmore Infant School, kitchen extract cleaning is usually booked for the holidays, when the canteen is closed.

Leave it or put it right?
TR19® is not law, but the Regulatory Reform (Fire Safety) Order 2005 is. The responsible person must assess and reduce fire risk, which in a kitchen includes the grease in the extract. TR19 is the benchmark insurers, fire officers and EHOs look to. When a site near Blackwater shuts unexpectedly, the people who rely on it notice at once.
Several systems or sites on one quote can make for a more efficient booking. Tell us about everything you’d like looked at and we’ll price it together.

Between visits
Looking after the system between visits is straightforward, and it helps at the next visit:
- Diarise the next clean as soon as you get the certificate
- Don’t let the canopy gutters overflow
- Wash or exchange the filters often
- Never cook with filters missing or out of place
The report gives a recommended date for the next clean, set from your daily cooking hours and the readings we took. A 3, 6 or 12-monthly maintenance plan keeps it on track, so the date isn’t missed.
Book the next clean before the last one runs out. If the kitchen starts cooking longer hours, the interval should be looked at again, and grease readings will show it.
