Grease, kitchens and Chells
The FSA’s food hygiene register includes about 9 pubs and bars within 1.5 miles or so of the middle of Chells. A pub or hotel kitchen that cooks every day builds up grease in its extract like any other. Environmental health officers from Stevenage council inspect food businesses in Chells. They look at how clean the premises and equipment are, and the kitchen extract is part of that. Our report lists what was cleaned and when, which is useful to have ready. Chells is covered by Hertfordshire Fire and Rescue Service. In most workplaces, including commercial kitchens, it’s the fire and rescue authority that enforces the Fire Safety Order.
Term dates shape school work: for a school like The Nobel School, an extract clean fits neatly into a half-term or summer break. If you run catering at a healthcare site, such as a hospital like Lister Hospital about 2.1 miles north-west, the extract may need cleaning more often than a part-time kitchen.
Chells is about 1 mile east of Stevenage, in Hertfordshire. Across the SG2 area, we can carry out canopy cleaning at your premises. Chells is one of 381 towns, villages and districts in Hertfordshire we cover for canopy cleaning. For sites nearby, see our Milton Keynes page, about 27 miles away.
Every address in SG2 and SG1 is covered for canopy cleaning, from busy streets to back roads. We cover sites on Scott Road, Eliot Road and Newton Road and the roads around them. Other places close to Chells include Stevenage (1 mile west), St Nicholas (1 mile north-west), Pin Green (1 mile west), Aston End (1 mile south-east) and Bedwell (1 mile south-west).

Landmarks near Chells
We work in commercial kitchens and buildings around Lodge Farm Primary School. For rail, the closest station is Stevenage station, about 1.8 miles south-west of the centre.

Canopy cleaning for kitchens and businesses in Chells
Every canopy we clean in Chells gets the same treatment: we remove the filters, clean the plenum and housing, then degrease the canopy shell. You get photos of the canopy before and after. Common call-outs are for smoke hanging around the canopy during service and fat running down the front of the hood, on canopy light fittings, island canopies and wall canopies.
Kitchens around a place like Chells are often in older buildings or single-storey extensions, where the duct may cross a roof void or climb an outside wall. Long horizontal runs like that hold grease and need access panels to reach.
Duct Doctor has 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’re fully insured.

Signs you need canopy cleaning in Chells
Air straight off the range hits the canopy first. Grease from the vapour lands on the canopy’s inner surfaces, its joints and its filters, and the plenum behind them collects the rest.
If you notice any of these, it’s worth a diagnosis:
- Heavy deposits behind the grease filters
- A hood coated in old grease
- Filters that clog soon after cleaning
- Fat running down the front of the hood
A hall kitchen that only cooks for events, whether near St Hugh & St John or elsewhere in Chells, still needs its extract cleaned, just less often.
Questions to ask before you book
- Proof of insurance
- Whether they recommend a next date
- Exactly which parts of the system are covered

Your questions about canopy cleaning in Chells
Can you come to Chells after we close?
Yes. We work evenings, overnight and at weekends. It means the site in Chells keeps running as normal. Your opening times are the first thing we ask for.
Can school kitchens in Chells be cleaned in the holidays?
Yes. The holidays are the usual time for school work. There are about 26 schools, colleges and universities on the FSA’s food hygiene register within about 1.5 miles of Chells. Just phone us on 0345 646 2711 or use the quote form with your term dates and we will plan around them.
What kinds of canopies do you clean?
Wall and island canopies, long cooking-line hoods and small single hoods. Each one is cleaned inside and out, with the plenum behind the filters.
Do you have insurance?
Yes, we’re fully insured. CHAS and SafeContractor accreditation sit alongside it, for sites that check contractor safety.
What causes grease to drip from the hood?
A full trough, gaps around the filters or a coated plenum. We clean all three and point out anything that’s causing it.
Can I just have the canopy cleaned instead of the whole system?
On its own, a canopy clean is a useful extra rather than a full TR19 clean. We will make clear on the report which parts were cleaned so nobody mistakes it for a full system clean.
What information do you need?
Only a few details: where it is, what kind of site, when it’s open and the access. Photos and any previous paperwork make it quicker. After that, simply phone us on 0345 646 2711, or send details by email.
Does the law say we must follow TR19?
Not in itself. TR19® is the benchmark insurers, fire officers and EHOs check against, and many insurers ask for proof of cleaning to it. The legal duty sits in the Regulatory Reform (Fire Safety) Order 2005, which applies in England and Wales.
Leave it or put it right?
Leaving the canopy until the next full clean can mean months of build-up. In a busy kitchen, the canopy and plenum can need attention between TR19 cleans, and readings or a look behind the filters will show it. Booking now means the visit to Chells is planned around you, not forced by a breakdown.
No two sites are the same, so we price each one individually. The size of the job, how we reach it, its condition and the working hours all play a part.

How the visit works
Every visit runs to the same pattern: sheeting and protection first, isolate whatever needs isolating, carry out the canopy cleaning, clear away and leave you the report. On site, the work takes an hour or two for one small canopy, longer where there are several. Evenings, weekends or a closed day all work for a site in a place like Chells.
- We look at the canopy, filters and troughs first.
- Out of hours, the range is switched off, cooled and covered.
- With the filters removed, the plenum and filter channels are cleaned.
- Inside and out, the hood and its troughs are cleaned.
- Filters are refitted, the area cleaned down and the photo report put together.
Preparing for the visit
- Make sure equipment near the work can be switched off and left to cool
- Let us know about permits to work or site inductions
- Move anything stored near the system

Staff cleaning versus specialist work
Some jobs should never be done in-house: entering ducts, working on fans, testing dampers and taking grease readings need training, the right equipment and safe access. That’s our job.
Day-to-day cleaning is something your team can do: wiping canopies, washing grease filters and recording it in a log. Inside the ducts, risers and fan is specialist work, and that is where we come in.
Looking after it afterwards
After the visit, a few habits help the work last:
- Clean the baffle filters often
- Give the canopy a wipe after service
- Use non-abrasive cloths on the hood
- Keep grease cups and drawers emptied
We point out anything we noticed while the canopy was apart: bent or poorly fitting filters, a light cover that is cracked, or troughs that fill too quickly. It’s a short list of what to watch, not a sales pitch.
Keep the fan running throughout service and for a short while after. Air that keeps moving carries less grease onto the canopy.
Landlords, agents and facilities managers
Under the Regulatory Reform (Fire Safety) Order 2005, the responsible person must assess and reduce fire risk, which may be the employer, owner, landlord, FM or managing agent. Where responsibility is shared, records matter even more.
Keeping records across a portfolio is half the battle. Each visit produces a dated report with pictures, ready to show insurers, fire officers or EHOs.
Honest limits
Not every problem is solved by canopy cleaning, and we’ll tell you before work begins. It does not solve:
- Grease filters too damaged to refit (they need replacing)
- A canopy too small for the cooking under it (that’s a design question)
- A light fitting that doesn’t work
If you are not sure, just call us on 0345 646 2711 or send us an email and we will give you a straight answer before booking.
