Common questions in Thornton Heath
What do you need to know about parking in Thornton Heath?
A loading bay, a visitor permit or off-street space near the site in Thornton Heath makes the visit easier to plan. Where restrictions apply in the day, an evening or overnight visit normally gets round them.
Which council inspects kitchens in Thornton Heath?
Food hygiene inspections in Thornton Heath are carried out by Croydon council. How often a business is inspected depends on the risk rating the council gives it, so it’s worth staying ready all year.
What happens if there are not enough access panels?
Sections out of reach are written down on the report, as TR19 expects. New panels can be fitted to reach them in future.
What’s the cleaning interval for extract ductwork?
BESA guidance sets minimum intervals by daily cooking hours: 3-monthly for heavy use, 6-monthly for moderate and 12-monthly for light use. Measured grease sets the real interval.
What’s involved in cleaning extract ducts?
We open each access panel and clean the section it reaches. Grease is scraped out first, then degreased, with readings taken before and after.
What about areas you cannot get to?
They’re marked on the report. In ductwork, new access panels are often the answer, which we can install.
What accreditations do you have?
We are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. CHAS, SafeContractor and ISO 9001 are in place too, and we carry full insurance.
How long will the duct clean take?
A short duct can be cleaned in a few hours, while long ducts and tall risers can need more than one visit. We plan the work around your kitchen.
Ductwork cleaning in Thornton Heath, done properly
In doctor’s terms, the ductwork is the system’s arteries: diagnose where grease has built up, clear it and confirm the result. Readings taken before and after show the difference, alongside before and after pictures. The work covers attenuators, horizontal duct runs and multi-storey ducts, and people most often call us about sections of duct with no access panels and a grease test showing the duct is overdue.
London kitchens are often tucked into basements or the back of a building, and the duct may run up through several floors before it discharges at the roof. In Thornton Heath, as elsewhere in the capital, a long duct run means more access points to open and more grease to remove.
Every visit ends with a written report and photos, so you have a record of what was done and when. Where the work is a TR19® Grease clean, the certificate is issued through the BESCA Vent Hygiene Elite portal.

Why act early in Thornton Heath
Insurers know the risk of a greasy duct. Many policies require TR19 cleaning, and a claim may be refused or reduced without evidence. A certificate that covers the ductwork is what they want to see. London sites work long hours, and the longer a job is left, the bigger it gets.
The cost depends on the size of the system, what state it’s in and access to every part of it. You get a fixed price before any work starts, so you know where you stand.

What ductwork cleaning looks like in Thornton Heath
The FSA’s food hygiene register includes about 15 pubs, bars and clubs and about 10 hotels and guest houses across Thornton Heath and its immediate surroundings (about a mile and a half). Wherever they cook, the canopy, duct and fan collect grease just as a restaurant’s do. Night work suits London kitchens, and roads and loading bays tend to be quieter too. Kitchens in Thornton Heath get their food hygiene inspections from Croydon council. An officer looking round a kitchen will see the canopy, and grease there is hard to miss. Our report lists what was cleaned and when, which is useful to have ready.
If you cook for passing trade around Thornton Heath station, the extract can be cleaned between your last and first customer. Bursars and site managers at schools such as Winterbourne Junior Girls' School tend to book extract cleaning for when the kitchen is empty. Volunteers running a hall kitchen near Church of St Stephen, or anywhere in Thornton Heath, may not know when the extract was last cleaned, and a grease test settles it.

For landlords and multi-site operators
The Fire Safety Order 2005 puts the duty to manage fire risk on the responsible person, which may be the employer, owner, landlord, FM or managing agent. With shared responsibility, good records help everyone.
Where a tenant occupies the premises but the landlord owns the building, the lease normally sets out who maintains what. We are happy to deal with either side, and the report can go to both.
Honest limits
Before you book, it helps to know what’s not included:

What we do, step by step
Before we leave, we walk the area with whoever is on site. We point out anything that couldn’t be reached or needs a follow-up, and the same goes into the written report. All told, the work takes anything from a few hours to several visits, depending on the length of duct. Most London sites can’t stop for the day, so work in Thornton Heath is typically done overnight, early in the morning or at weekends.
- We start by working out how the duct runs and where it can be opened.
- Set points along the runs are tested for grease.
- Access panels are opened and heavy deposits scraped out by hand.
- Horizontal runs and risers are then degreased by the method that suits the deposit.
- We test again, take photos and note any part that couldn’t be reached.
Getting ready for the visit
- Name a contact who can let us in at the agreed time
- Let us know about parking and loading
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas

Related advice
Between visits
Aftercare is simple, and it helps at the next visit:
- Diarise the next duct clean
- Make sure filters are seated properly
- Get panels fitted where the duct couldn’t be cleaned
- Keep access panels clear of stored items
Every panel we open is refitted when we finish, and the area around them is cleaned down. Waste grease and water are taken away.
Keep to the cleaning interval on the report. A change in cooking hours may change the interval under BESA guidance, and grease thickness testing will show it.

What staff can safely do
Some jobs should never be done in-house: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease call for the right kit, training and safe access. Leave those to us.
Keep a record of what your team does. A simple log of filter washes, wipe-downs and checks helps show that the system is managed between specialist visits, alongside our reports.
How the job changes from site to site
Bends and transitions
Grease tends to pile up at elbows. We clean it back by hand and with degreaser, and readings are taken there before and after.
Vertical risers
A riser takes the duct up through one or more floors. Grease collects on the walls and at the foot of the riser, so the base is one of our test points.
