Ductwork cleaning in Ayot St Peter, Hertfordshire
Need ductwork cleaning in Ayot St Peter? We diagnose first, fix the price and book the work around your hours, finishing with a written report and photos.
- Gaps where access panels were never fitted
- Heavy grease at the base of a riser
- Readings above 200 microns from a grease thickness test
Looking after it afterwards
After the visit, a few habits help the work last:
- Make sure filters are seated properly
- Book the next clean before the recommended date
- Get panels fitted where the duct couldn’t be cleaned
- Don’t block access panels with shelving or stock
Every panel we open is refitted when we finish, and the surrounding area is left clean. Waste grease and water are taken away.
Book the next duct clean before the date passes. A change in cooking hours may change the interval under BESA guidance, and grease thickness testing will show it.
About our ductwork cleaning in Ayot St Peter
Duct Doctor has cleaned kitchen extract ductwork since 2009, working across London and the South East. We’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, with each certificate issued through the BESCA portal. We’re often asked to deal with grease leaking from duct joints and grease pooling at the foot of the riser, on multi-storey ducts, attenuators and bends and junctions.
In a small place like Ayot St Peter, kitchens are often in older or extended buildings, with long single-storey duct runs, where grease settles in the flat sections. Access, parking and timings are agreed before the day.
We are CHAS and SafeContractor accredited, we hold ISO 9001 and we’re fully insured. On top of that, we’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, trading since 2009.

Kitchen extracts in Ayot St Peter
The FSA’s food hygiene register shows about 10 restaurants, cafés and canteens within roughly a mile and a half of the centre of Ayot St Peter. Where they cook under a canopy, grease doesn’t stop at the filters: it settles along the duct and up the riser. Ayot St Peter sits within the area of Hertfordshire Fire and Rescue Service. Its fire safety officers can audit commercial kitchens, and grease in the extract is part of a kitchen’s fire risk. In Ayot St Peter, food businesses are inspected by environmental health officers from Welwyn Hatfield council. They look at how clean the premises and equipment are, and the kitchen extract is part of that. Keeping each certificate and photo report on file helps show the extract is looked after.
If you run catering at a historic house or estate in the area (Shaw's Corner is about 1.4 miles north-west), event kitchens in older buildings often have awkward duct runs that need planning. Healthcare kitchens cannot easily close, so their extracts are cleaned overnight or between meal services; the nearest hospital to Ayot St Peter is Queen Elizabeth II Hospital, about 3.6 miles south-east.

Multi-site and managed buildings
Under the Regulatory Reform (Fire Safety) Order 2005, the responsible person must assess and reduce fire risk, and that can be the employer, the owner, a landlord, a facilities manager or a managing agent. With shared responsibility, good records help everyone.
For anyone managing more than one site, we can plan visits across the whole estate and price them together. Each site gets its own report and photos, so each one has its own record.
How the visit works
Your staff don’t need to do much on the day. A contact on site lets us in at the agreed time and points us to the system, and the rest is down to us. Before we leave, the area is tidied and the paperwork follows. Photos of the system and how to reach it help us plan a visit to Ayot St Peter.
- First the duct route is traced and every access point noted.
- We measure grease thickness at set points before cleaning.
- Through the access panels, thick grease is removed by hand first.
- Horizontal runs and risers are then degreased by the method that suits the deposit.
- Post-clean readings and pictures go into the report, with any unreachable section listed.
Preparing for the visit
- Mention any locked doors, roof access or ceiling voids
- Clear the space around the work
- Tell us about site rules, permits or sign-in

Related advice
Common problems we fix in Ayot St Peter
The further the air travels from the cooking, the cooler it gets. Cooling air drops its grease onto the inside of the duct, so duct runs keep collecting grease long after the canopy.
What we’re most often called out for:
- A duct clean needed for an insurer
- Grease pooling at the foot of the riser
- Stale grease odours from the duct
- A grease test showing the duct is overdue
Bursars and site managers at schools such as Monk's Walk School tend to book extract cleaning for when the kitchen is empty.
Questions to ask before booking
- Whether a written report and photos are included
- If they look at the system before pricing
- What insurance they carry
- If the quote is a fixed price or an estimate
How the job changes from site to site
Access panels
Extra panels can be installed where there are gaps, making future cleans more complete. The survey shows where they’re needed.
Bends and transitions
A bend can hold far more grease than a straight run of the same length. We clean it back by hand and with degreaser, and readings are taken there before and after.
What affects the quote in Ayot St Peter
Some jobs are bigger than they look, and some smaller. What affects the quote:
- What state the system is in
- The scale of the work
- Site requirements such as sign-in and permits
- One-off work versus a regular cycle
You won’t find a price list here, because the cost depends on the site in front of us. For a fixed quote, call us on 0345 646 2711 or use the quote form, and we will explain what it covers.
What to send for a quote
Photos let us diagnose from a distance. The most useful are:
- Your last certificate, test record or report
- A few general shots of the system
- Close-ups of filters, grilles, hatches or access panels
- The site address and the type of premises
Getting a quote does not take long. Send a few details and photos, and we normally reply with a fixed quote within one working day. Where a survey is needed, we arrange a time that suits the site.
In-house cleaning or a specialist?
When your team notices a problem between visits, such as dripping grease, a noisy fan, a smell or a filter that will not come clean, it’s best reported rather than tackled in-house. We can diagnose it and quote.
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.
Ayot St Peter: your questions answered
Can a school canteen extract in Ayot St Peter be done out of term time?
Yes. The holidays are the usual time for school work. The FSA’s register shows about 6 schools and colleges with food registrations within roughly a mile and a half of Ayot St Peter. You can give us a ring on 0345 646 2711 or drop us a line with the dates the site is empty.
Do you cover smaller places like Ayot St Peter?
Yes. Villages and rural sites across the South East are part of our work, Ayot St Peter included. A survey first, from pictures or a visit, means we arrive with the right kit.
Which accreditations do you hold?
We hold CHAS, SafeContractor and ISO 9001, alongside BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease. Vent Hygiene Elite is run by BESCA and independently audited.
What if part of the duct can’t be reached?
Every reachable section is cleaned and the rest recorded. Fitting extra access panels is the usual answer, and we can do that for you.
Will the duct clean disrupt the kitchen?
The duct is cleaned out of hours, evenings, overnight or at weekends. The extract and cooking equipment need to be off.
Are you fully insured?
Yes, fully. We also hold CHAS and SafeContractor, for sites that check contractor safety.
Can one contract cover all our sites?
Yes. One number covers all your sites in our area, and visits can be set on a regular cycle.
What is TR19?
