Kitchen Extract Cleaning in Colney Heath
Our technicians work in Colney Heath on TR19 Grease cleaning of complete kitchen extract systems, from canopy to discharge. Out-of-hours visits, a fixed quote and a written report with pictures as standard.
- Rancid smells from grease in the duct
- Ductwork thick with old, hardened grease
- Missing paperwork after a change of operator
What a clean won’t put right
An honest diagnosis matters more to us than a booking, so here’s what kitchen extract cleaning won’t do:
- An undersized canopy or fan
- Ductwork that’s corroded, split or leaking (that is for a ductwork contractor)
- A fan motor or bearings that have failed (that needs a fan repair or replacement)
Not sure which it is? You can ring 0345 646 2711 or drop us a line and we will tell you honestly.
Parts of the system we cover
- Extract fans
- Canopies and hoods
- Plenums and filters
- Vertical risers
- Discharge points
- Horizontal duct runs
Kitchen extract cleaning in Colney Heath
Duct Doctor has been cleaning kitchen extract systems since 2009. As a BESCA Vent Hygiene Elite member, we clean to BESA TR19® Grease, and we hold CHAS, SafeContractor and ISO 9001 and are fully insured. We’re often asked to deal with a new tenancy or takeover with no cleaning history and grease drips onto cooking equipment, across extract fans, horizontal duct runs and canopies and hoods. Canopy cleaning, extract cleaning and duct cleaning are often used to mean the same thing, but a proper TR19® clean in Colney Heath covers all of it, from the hood to the fan.
Before we clean, we look at where the grease is: wet film or deposit thickness readings show which parts of the duct need the most attention, and the same readings after the clean show the result.
For a kitchen in or near Colney Heath, the visit is planned around opening hours and the journey, and the clean covers the whole system, as it would anywhere: canopy to discharge, then a TR19® certificate and a photo report.
Good records are part of the job. You get a written report with photos after every visit, covering the work done, any areas we couldn’t access and a recommended next date. File it in your maintenance log so it’s to hand when an insurer or inspector asks.

Kitchen extracts in Colney Heath
There are about 37 restaurants, cafés and canteens and about 14 takeaways and sandwich shops within roughly a mile and a half of the centre of Colney Heath, according to the Food Standards Agency’s register. Any of them cooking under a canopy is sending grease into its ductwork every service. The fire and rescue service for Colney Heath is Hertfordshire 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. Kitchens in Colney Heath get their food hygiene inspections from St Albans City council. A greasy canopy or dripping filters are the sort of thing an inspection can pick up. Keeping each certificate and photo report on file helps show the extract is looked after.
Healthcare kitchens can’t easily close, so their extracts are cleaned overnight or between meal services; the nearest hospital to Colney Heath is Hill End Hospital, about 2.3 miles west. If your kitchen is in a listed or historic building, like the houses around Colney Heath (Hatfield House is about 2.3 miles north-east), fitting access panels needs care. Term dates shape school work: for a school like Colney Heath Junior Mixed Infant and Nursery School, an extract clean fits neatly into a half-term or summer break.

Your questions about kitchen extract cleaning in Colney Heath
Will you come out to Colney Heath?
Yes. Villages and rural sites across the South East are part of our work, Colney Heath included. Photos of the system and directions to the site help us plan the visit.
Who inspects food businesses in Colney Heath?
Kitchens in Colney Heath are inspected by St Albans City council’s environmental health officers. Ratings are published by the Food Standards Agency, so a clean extract and good records are worth keeping up.
What information do you need?
Only a few details: the address, the site type, your opening hours and how we reach the system. Photos and the last report help too. Then phone us on 0345 646 2711 or drop us a line.
How much does kitchen extract cleaning cost in Colney Heath?
We don’t publish prices, because the cost depends on the job: how big it is, what state it’s in, how we reach it and the working hours. You get a fixed price before work begins.
Can you set up regular visits?
Yes. Plans on a 3, 6 or 12-monthly cycle are available, to suit the system and how it’s used.
What types of premises do you cover?
Any site with a kitchen or a ventilation system to look after, from a single café to a large school. We work with hotels, schools, care homes, offices, retail and leisure sites.
How often should a kitchen extract be cleaned?
The minimum is set by BESA guidance on daily use, from 3-monthly to 12-monthly. Kitchens that fry or grill a lot may need cleaning sooner, and readings will tell you.
Which parts of the extract do you clean?
We clean every part the grease travels through. Canopy, plenum, filters, ductwork, risers, fan and discharge are all included, reached through access panels where needed.
Why it’s worth doing now in Colney Heath
TR19® is not law, but the Regulatory Reform (Fire Safety) Order 2005 is. It puts a duty on the responsible person to assess and reduce fire risk, and in a kitchen that means keeping extract grease under control. Cleaning to TR19 is the recognised way to show you’ve done it. Our emergency line runs 24/7, but a planned visit to Colney Heath is calmer for everyone.
Putting the work off seldom saves money. Build-up, wear and faults tend to get worse, not better, and a neglected system can mean more work. If you’re unsure, call 0345 646 2711 or drop us a line and we’ll give you an honest view and a fixed quote.

What happens on the day
Our technicians bring everything the work needs, including protection sheets, the right tools and access kit. All we need from you is clear access and the right equipment switched off. On site, the work takes anything from a few hours to a full night, depending on the size of the system. The timing of a visit to Colney Heath is set by you, and the travel is our side of the planning.
- First comes a survey of the whole system, by pictures or a visit.
- Grease readings are taken at set points and you get a fixed quote.
- Once the kitchen has closed and the equipment has cooled, we sheet and protect the area.
- Canopy, plenum, filters, duct runs, risers, fan and discharge are all cleaned to TR19® Grease.
- We test again, photograph the result and issue your TR19 certificate and photo report.
How to prepare
- Mention any locked doors, roof access or ceiling voids
- Move anything stored near the system
- Name a contact who can let us in at the agreed time

What else we do in Colney Heath
Looking after it afterwards
So the system stays in good health:
- Clean grease off the canopy surfaces regularly
- Refit filters properly after cleaning
- Keep the extract on whenever the range is lit
- Keep grease collection points emptied
You leave with a date for the next clean, based on your cooking hours and the grease we measured. A 3, 6 or 12-monthly maintenance plan keeps it on track, so the date is not missed.
Report drips, smells or a noisy fan early. Grease dripping from the canopy, a burning smell or a fan that sounds rough are all signs of build-up, and a grease thickness test can confirm it.
Multi-site and managed buildings
Landlords, managing agents and facilities managers book us, not only the businesses that use the systems. Shared systems, like a riser serving several units, need a clear agreement on who books the work, and we are happy to quote for all of it.
Records are where multi-site compliance often slips. Every visit ends with a dated report and pictures, so you can show an insurer or inspector what was done at each site.
What affects the cost of kitchen extract cleaning
Before we fix a price, we need to know a few things. We check:
- One-off work versus a regular cycle
- How easy every part is to reach
- The condition we find in the survey
- Working hours and out-of-hours timing
The cost depends on the size of the system, the condition it’s in and how easy it is to reach. You get a fixed price before work begins, so you know where you stand.
What we need to know
What to send for a quote:
- Your opening hours and when the area is out of use
- The postcode and the type of business
- Wide photos of the system and the area around it
- Any access panels or hatches you can see
For kitchen extract cleaning in Colney Heath, call 0345 646 2711 or drop us a line. Let us know the site type and the opening hours, and send pictures or your last report if you can. We typically send a fixed quote within one working day.
Staff cleaning versus specialist work
If your staff spot something between visits, such as dripping grease, a noisy fan, a smell or a filter that won’t come clean, they should report it rather than try to fix it. We can diagnose it and quote.
For ventilation and air handling systems, in-house care is mostly about checks: keeping grilles clear, noting unusual noise or smells and logging filter changes. Cleaning inside ducts and units is specialist work.
