Kitchen extract cleaning in Bishopsgate, Surrey
Kitchen extract cleaning for Bishopsgate, from a team that has been trading since 2009. Out-of-hours visits and 24/7 emergency callout.
- Ductwork thick with old, hardened grease
- Fat running down the canopy edge
- Stale cooking odours from the system
Why deal with it now?
Grease that’s left only gets thicker. BESA guidance says the mean should not go above 200 microns between cleans, and 500 microns or more at any point needs immediate spot cleaning. The longer it’s left, the bigger the job becomes. It’s simpler to plan the work at Bishopsgate now than to arrange it in a hurry later.
You will not find a price list here, because the cost depends on the site in front of us. Call for a fixed quote, and we’ll talk you through it.

Kitchen extract cleaning for kitchens and businesses in Bishopsgate
Any kitchen we clean in Bishopsgate gets exactly the same specification as everywhere else we work. The job starts with a survey and grease readings, then works through canopy, plenum, filters, ductwork, fan and discharge. At the finish there’s a TR19 certificate and a before and after photo report. If you have a system with no record of a TR19 clean and a new tenancy or takeover with no cleaning history, we can put it right, from plenums and filters, horizontal duct runs and canopies and hoods onwards. If you need a kitchen extract clean in Bishopsgate, one call covers the survey, the clean and the paperwork.
Each job starts with a look at where grease has built up: grease readings at set points tell us where the heaviest deposits are, and the same readings after the clean show the result.
In a village or hamlet like Bishopsgate, the kitchens that need extract cleaning are typically a pub, a school, a care home or a hall kitchen, wherever there is one. Each still has a canopy and duct that collect grease, whatever the size of the place.
We have been trading since 2009, as a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we are fully insured.

Bishopsgate: your questions answered
Can you get to a site in Bishopsgate?
Yes, we work in villages as well as towns, and Bishopsgate is covered. A survey first, from pictures or a visit, means we arrive with the right kit.
Do you work at weekends in Bishopsgate?
Yes, nights and weekends are routine for us. The site is handed back ready to open. Your opening times are the first thing we ask for.
What paperwork comes with a kitchen extract clean?
A TR19 certificate and a photo report. Certificates are issued through the BESCA Vent Hygiene Elite portal, and the report shows before and after photos, readings, any areas not reached and the next clean date.
How much does kitchen extract cleaning cost?
We don’t publish prices, because the cost depends on the job: the size of the system, its condition, access and when we can work. We fix the price before any work starts.
Is TR19 a legal requirement?
TR19 is not written into law, but the responsible person still has a legal duty under the Fire Safety Order 2005. TR19 is the standard insurers and fire officers expect, and many policies require it.
Will my insurer ask for a TR19 certificate?
Grease-filled ducts can carry fire well beyond the kitchen. Many policies say the extract must be cleaned to TR19, and a claim may be reduced without proof, so keep every certificate.
What’s the right cleaning interval for a kitchen extract?
BESA guidance gives minimum intervals of 3, 6 or 12 months, depending on daily cooking hours. Kitchens that fry or grill a lot may need cleaning sooner, which grease thickness testing will show.
Are you accredited for kitchen extract cleaning?
We’re members of Vent Hygiene Elite, the scheme run by BESCA, and we clean to BESA TR19® Grease. We hold CHAS, SafeContractor and ISO 9001 too, and we are fully insured.

When something else is needed
A few issues sit outside what this work can do:
- A fan motor or bearings that have failed (that needs a fan repair or replacement)
- Ductwork that’s corroded, split or leaking (that is for a ductwork contractor)
- Extraction that can’t cope with the cooking because of its design
Not sure which it is? You can ring 0345 646 2711, or email photos and we will tell you honestly before booking.
Where we work
- Plenums and filters
- Vertical risers
- Discharge points

What we do, step by step
When we arrive, we check the system against the survey or the pictures you sent. Anything unexpected is raised with you before we go further. From there, it takes one visit for most kitchens, while large or complex systems may need more than one. If the van will struggle with a lane or gateway near Bishopsgate, let us know and we will plan around it.
- We survey the system, from your photos or on site, canopy to discharge.
- We take grease readings at set points and give you a fixed quote.
- On the night, the equipment is off and cool and the kitchen is sheeted.
- Filters, canopy and plenum are cleaned, then the ducts, risers, fan and discharge.
- Readings are repeated, pictures taken, and your TR19 certificate and photo report issued.
Before we arrive
- Make sure equipment near the work can be switched off and left to cool
- Make sure someone can let us in and lock up afterwards
- Agree a time when the area can be out of use

Advice
Grease, kitchens and Bishopsgate
Food Standards Agency data counts about 48 cafés, restaurants and staff canteens and about 8 takeaways and sandwich shops within 1.5 miles or so of the middle of Bishopsgate. Those that fry, grill or roast under a canopy need their extracts cleaned at intervals set by how long they cook. Food hygiene inspections in Bishopsgate are the job of Runnymede council’s environmental health team. They look at how clean the premises and equipment are, and the kitchen extract is part of that. Before-and-after photos from each clean are a simple way to show the extract is in hand. Bishopsgate is covered by Surrey Fire and Rescue Service. The Fire Safety Order puts the duty on whoever runs a kitchen to control its fire risk, and a greasy duct is fuel.
If you run catering at a healthcare site, such as a hospital like King Edward VII Hospital about 2.7 miles north-west, the extract may need cleaning more often than a part-time kitchen. For schools such as St John's Beaumont School, kitchen extract cleaning is usually booked for the holidays, when the canteen is closed.
Bishopsgate is about 2 miles north-west of Egham, in Surrey. From the centre of Bishopsgate to the outskirts, kitchen extract cleaning is available to all kinds of commercial premises, from small sites to large estates.

How the job changes from site to site
Restaurant and pub kitchens
Restaurants and pubs tend to cook long hours with plenty of frying and grilling, which can put them in BESA’s 3 or 6-monthly bands. We clean after close or before opening.
Ductwork and risers
Long flat runs of duct are where grease collects. Each run is cleaned through its access panels, recording any that can’t be reached.
Managing agents and facilities teams in Bishopsgate
The Fire Safety Order 2005 puts the duty to manage fire risk on the responsible person, and that can be the employer, the owner, a landlord, a facilities manager or a managing agent. Where responsibility is shared, records matter even more.
Where a tenant occupies the premises but the landlord owns the building, the lease normally sets out who maintains what. We’re happy to deal with either side, and the report can go to both.
Staff cleaning versus specialist work
Some jobs should never be done in-house: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease need training, the right equipment and safe access. Leave those to us.
When your team notices a problem between visits, such as dripping grease, a noisy fan, a smell or a filter that won’t come clean, it’s best reported rather than tackled in-house. We will take a look and give you a fixed quote.
What we’re called out for in Bishopsgate
Hours of cooking are the biggest factor. Under BESA guidance, heavy use of 12 to 16 hours a day means a clean at least every 3 months, moderate use every 6 months and light use every 12. They are minimums: measured grease levels set the real interval.
Common reasons sites call us include:
- A TR19 certificate needed for the insurer
- Heavy grease build-up inside the duct runs
- Rancid smells from grease in the duct
- A smoky, hot kitchen with weak extraction
A hall kitchen that only cooks for events, whether near Royal Chapel of All Saints or elsewhere in Bishopsgate, still needs its extract cleaned, just less often.
