Ductwork cleaning in Colworth, West Sussex
One call covers ductwork cleaning in Colworth, from survey to sign-off. CHAS and SafeContractor accredited, ISO 9001 and fully insured.
- A grease test showing the duct is overdue
- Duct runs with no cleaning record
- Heavy grease at the base of a riser
What we do, step by step
There are three stages on the day: getting the area ready, doing the work and signing it off. Getting ready means protecting surfaces and switching off what needs to be off, and the sign-off is a written report with photos. The middle part takes longest, which takes from a few hours to more than one visit, depending on duct length and access. The timing of a visit to Colworth is set by you, and the travel is our side of the planning.
- First the duct route is traced and every access point noted.
- 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.
- Post-clean readings and pictures go into the report, with any unreachable section listed.
Before we arrive
- Tell us about site rules, permits or sign-in
- Mention any locked doors, roof access or ceiling voids
- Agree a time when the area can be out of use
Ask for a quote
Some systems can be priced from pictures; others need a survey. Big or complicated sites, and systems that are hard to see in photos, get a survey first. Either way, the quote is fixed before any work is booked.

Ductwork cleaning in Colworth, done properly
Not sure when the ductwork was last cleaned? Tell us about the system when you phone us on 0345 646 2711 or use the quote form, and a fixed price will follow, usually within one working day. The work covers vertical risers, bends and junctions and horizontal duct runs, and the jobs we see most are a grease test showing the duct is overdue and stale grease odours from the duct.
Work in a small place like Colworth starts with a call to agree access and timings, and the clean itself is the same full TR19® job as in any town: canopy, filters, duct, fan and discharge, with a certificate and photo report at the end.
For insurers and inspectors, the record counts. So every job comes with a written report and photos, plus a TR19® certificate through the BESCA VHE portal where the work is a TR19® Grease clean.

What a clean won’t put right
To be straight with you, some problems need a different fix:
- Duct sealed behind fixed ceilings or walls
- A worn-out fan that needs replacing
- A duct that’s too small or badly routed for the kitchen (a design issue)
If in doubt, call us on 0345 646 2711, or send details by email and we will say what we think.

Landlords, agents and facilities managers
We work for landlords, managing agents and facilities managers as well as the people running the site. Where a system serves more than one tenant, such as a shared riser, it helps to agree who arranges the work, and we can quote for the whole system.
Keeping records across a portfolio is half the battle. Each visit produces a dated report with photos, ready to show insurers, fire officers or EHOs.
Grease, kitchens and Colworth
Colworth lies within about 3 miles of the sea. Salt in the air is hard on rooftop fans, discharge cowls and fixings, so we check them for corrosion as well as grease. Look up Colworth on the FSA’s food hygiene register and you’ll find about 6 cafés, restaurants and staff canteens and about 8 takeaways and sandwich shops across Colworth and its immediate surroundings (about a mile and a half). Where they cook under a canopy, grease does not stop at the filters: it settles along the duct and up the riser. Kitchens in Colworth get their food hygiene inspections from Chichester council. An officer looking round a kitchen will see the canopy, and grease there is hard to miss. Keeping each certificate and photo report on file helps show the extract is looked after.
If you look after a school kitchen, at a school such as Bartons Primary School or anywhere near Colworth, the holidays are the usual time for a TR19® clean. Healthcare kitchens, like those at hospitals such as Bognor Regis War Memorial Hospital (about 2.2 miles south-east), often cook for long hours, which puts them in BESA’s heavier-use bands. Goodwood House, about 4 miles north-west, is one of the historic houses near Colworth; if you run event catering at a venue like that, cleans can be booked between functions.
Colworth is about 2 miles north of Bognor Regis, in West Sussex. Whether your site is in the middle of Colworth or further out, ductwork cleaning is available to all kinds of commercial premises, from small sites to large estates. Across West Sussex, we cover 371 places, and Colworth is one of them. Our Portsmouth page covers sites nearby (16 miles or so).

How the job changes from site to site
Attenuators and discharge
Some systems have attenuators to reduce noise, and their linings can soak up grease. We clean what can be reached and note anything that can’t.
Access panels
We can fit new access panels where the duct needs them, making future cleans more complete. We will recommend where they should go.
Between visits
How long the results last depends on use and care. We suggest:
- Keep grease filters clean and fitted whenever you cook
- Don’t switch the extract off early
- Store the certificate with the fire risk assessment
- Have the grease measured if cooking hours go up
File the paperwork in the maintenance log. It’s the evidence an insurer or inspector may ask for, and the photos make the duct’s condition easy to see.
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.
Staff cleaning versus specialist work
Good housekeeping makes our visits easier, not unnecessary. Clean filters and tidy surfaces slow the build-up, but the parts you cannot see still need a specialist at the right interval.
In-house cleaning and specialist cleaning do different jobs. Wiping filters daily and washing them weekly keeps the visible parts in order, but grease that has passed the filters is out of reach. That part needs specialist access and equipment.
What happens if it’s left?
Fire inside a duct is out of sight and out of reach. The duct can carry it to rooms, floors or roof spaces well away from the kitchen, which is why the duct matters as much as the canopy. In a small place like Colworth, a system that fails can take a site out of use.
We don’t list prices on the website, because the cost depends on the site in front of us. For a fixed quote, ring 0345 646 2711 or email us, and we’ll talk you through it.

FAQs for Colworth
Which environmental health team covers Colworth?
That’s Chichester council, whose environmental health officers carry out food hygiene inspections in Colworth. It helps to keep the extract cleaning records with your food safety paperwork, so they’re ready if asked for.
Do you work in villages like Colworth?
Yes, Colworth is part of our area, however small the site. Let us know about access, parking and anything unusual about getting there when you book.
What does TR19 mean?
It’s the industry benchmark for cleaning ventilation and kitchen extract systems, written by BESA. It covers how systems are inspected, cleaned and checked and expects a risk-based approach.
What types of premises do you cover?
Any commercial site with kitchens or ventilation, from a small pub to a hospital. Hotels, schools, care homes, offices, shops and leisure sites are all part of our work.
Can you price the work without visiting?
In many cases, yes. With good pictures, the site type and your last report, we can price many jobs. Larger or hidden systems need a survey on site first.
How long does it take to clean extract ducts?
A short duct can be cleaned in a few hours, but long or complex ducts may take several visits. Visits are planned out of hours.
What do you do to protect the area?
Floors and surfaces near the work are sheeted before any work starts, and anything we remove is contained. At the end, the area is cleaned down.
Do you survey before quoting?
Yes. Photos often do the job, while bigger or harder-to-see systems are surveyed on site.
