About our ductwork cleaning in Shephall
We treat ductwork like a doctor treats arteries: find the blockages, clear them, then check the flow is right. Grease readings before and after give you the evidence, alongside before and after pictures. The work covers bends and junctions, access panels and multi-storey ducts, and the jobs we see most are grease pooling at the foot of the riser and readings above 200 microns from a grease thickness test.
For a smaller kitchen near Shephall, a TR19® clean is the same job as anywhere: canopy, filters, plenum, duct, fan and discharge. The visit is booked around your opening hours, and the journey is planned ahead.
The paperwork matters as much as the work. You get a written report with pictures after each visit, listing what was done, anything we couldn’t reach and when the next visit is due. File it in your maintenance log so it’s ready for an insurer, fire officer or EHO.

Grease, kitchens and Shephall
The FSA’s food hygiene register includes about 21 pubs and bars and about 4 hotels and B&Bs in Shephall and the streets around it, up to about 1.5 miles out. A pub or hotel kitchen that cooks every day builds up grease in its extract like any other. Shephall sits within the area of Hertfordshire Fire and Rescue Service. Fire and rescue authorities enforce the Fire Safety Order in most non-domestic premises, and in a kitchen that fire risk includes the grease in the extract. Food hygiene inspections in Shephall are the job of Stevenage council’s environmental health team. The cleanliness of the kitchen and its equipment, extraction included, is part of what they check. Keeping each certificate and photo report on file helps show the extract is looked after.
If you run a church or community hall kitchen, near Church of Saint Mary or elsewhere in Shephall, its extract still collects grease from every lunch and event. If you run catering at a healthcare site, such as a hospital like Lister Hospital about 2.7 miles north-west, the extract may need cleaning more often than a part-time kitchen. Bursars and site managers at schools such as Peartree Spring Primary School tend to book extract cleaning for when the kitchen is empty.
Shephall is about 1 mile south of Stevenage, in Hertfordshire. Shephall gets the same approach as every site we work on: a survey first, a fixed quote, work timed around your hours and a report with pictures. Shephall is one of 381 towns, villages and districts in Hertfordshire we cover for commercial clients. We also work in London, around 27 miles away.

The process
Each visit runs to the same pattern: sheeting and protection first, isolate whatever needs isolating, do the work, clear away and leave you the report. On site, the work takes anything from a few hours to several visits, depending on the length of duct. In a smaller place like Shephall, parking is rarely the issue, but tell us about gates, roof access and opening hours.
- First we diagnose: the route, the access and the grease levels.
- You get a fixed price before work starts.
- We clean section by section, working from panel to panel.
- Bends, risers and the base of each riser get extra attention.
- Readings, pictures and a recommended next clean date complete the job.
Getting ready for the visit
- Arrange a key holder or contact on site
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
- Tell us the best time to work, such as after service or at a weekend

What else we do in Shephall
What the work involves, part by part
Attenuators and discharge
Some systems have attenuators to reduce noise, but they can hold grease in their linings. They’re cleaned where possible and recorded if not.
Access panels
Every section of duct is cleaned through an access panel. Where there are none, those sections can’t be cleaned and the report has to say so.
Fixed quotes for ductwork cleaning in Shephall
A fixed price needs a few facts first. We check:
- How many systems or sites are involved
- The scale of the work
- Access, including roofs, risers and ceiling voids
- The condition of the system
Working hours, access and the scale of the site all affect the cost. We take each of them into account and give you a fixed price before any work starts.
Helping us quote
We can often survey from pictures. The most useful are:
- The paperwork from the last visit, if you have it
- Problems your staff have spotted
- Your opening hours and when the area is out of use
- The site address and the type of premises
Here’s what helps us quote: the address, the type of site and when it’s open, a few pictures and the last certificate or report, if there is one. Once you have those, phone us on 0345 646 2711 or send us an email.
Shephall questions
Which fire authority looks after Shephall?
It’s Hertfordshire Fire and Rescue Service, which covers Shephall. TR19® is not law, but it’s the benchmark many fire officers and insurers look to when they ask how often the extract is cleaned.
Who inspects food businesses in Shephall?
Kitchens in Shephall are inspected by Stevenage council’s environmental health officers. It helps to keep the extract cleaning records with your food safety paperwork, so they’re ready if asked for.
How do you know if the ductwork needs cleaning?
We measure it. Using a Wet Film Thickness Test or Deposit Thickness Test, we check the grease at set points. A mean above 200 microns, or 500 microns at any point, means it’s due.
Can you set up regular visits?
Yes. Regular plans can run on 3, 6 or 12-monthly cycles, to suit the system and how it’s used.
How long does it take to clean extract ducts?
Allow a few hours for a short run, longer for long runs and tall risers. We will confirm the time when we quote.
Can you quote from photos?
Yes, for many jobs. Send a few wide photos plus close-ups of panels, filters or grilles, and a fixed quote usually follows within one working day. If photos aren’t enough, we will survey first.
Will I get a report after the ducts are cleaned?
A full system clean comes with a TR19 certificate and a photo report. The report shows readings, pictures and any sections we couldn’t reach.
Is Shephall in your area?
Yes. Shephall is part of the area we cover, as part of our area across London and the South East.
Landlords, agents and facilities managers
Multi-site operators often want one contractor and one number. We work across London and the South East, so visits at different addresses can be planned together and kept on a regular cycle.
Facilities teams in offices, schools and healthcare sites book us too across Hertfordshire. Work can be phased by floor, building or site around the people who use them.
What your team can do, and what needs us
A few tasks are always specialist work: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease need training, the right equipment and safe access. Leave those to us.
Staff cleaning and specialist work are not the same thing. A daily filter wipe and a weekly filter wash keep grease down at the front of the system, but they don’t reach the grease that builds up further in. Reaching it takes a specialist with the right equipment.
Leave it or put it right?
Insurers know the risk of a greasy duct. Many policies require TR19 cleaning, and a claim may be refused or reduced without evidence. Your certificate and photo report show the ducts were cleaned. It’s easy to lose track of when the work was last done on a quieter site.
Combining work into one visit or one programme can make for a more efficient booking. Mention every system or site you need covered, and you will get one fixed quote.

Between visits
Once we’ve finished, these simple steps help:
- Flag drips from the duct right away
- Run the extract fan throughout service
- Book the next clean before the recommended date
- Check readings when the menu changes
Grease readings are taken again at the same set points, so the report shows the before and after figures. Photos of each section go alongside them.
The less grease gets past the canopy, the cleaner the duct stays. Keep the filters clean, well fitted and in place whenever you cook.
