How we price ventilation duct cleaning
A fixed price needs a few facts first. We look at:
- Site requirements such as sign-in and permits
- How big the system is
- One-off work versus a regular cycle
- What state the system is in
We don’t list prices on the website, because each job is priced on what it involves. For a fixed quote, ring 0345 646 2711 or send us an email, and we will explain what it covers.
What to send for a quote
When you contact us, it’s useful to have:
- Where the site is and what kind of site it is
- Your last certificate, test record or report
- Where the plant sits or the system leaves the building, such as a roof or outside wall
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
There’s no standard price list, because no two systems are the same. Instead, we look at your site first, from photos or a survey, then send a fixed quote. To start, call 0345 646 2711, or send details by email.
Ventilation duct cleaning in Offham, done properly
TR19® Air is the part of BESA’s TR19® that deals with general supply and extract ventilation. It works by inspecting first and cleaning where the risk calls for it, so every job starts with a look inside the ducts. We’re often asked to deal with ductwork never cleaned since it was installed and poor airflow from the vents, across supply ductwork, hospitals and care homes and grilles and diffusers.
Rural buildings with mechanical ventilation, such as care homes and country hotels, often keep their units in roof spaces or outbuildings, which makes them easy to overlook.
Each visit ends with a written report and photos, so there’s a dated record of the work. Where the work is a TR19® Grease clean, the certificate is issued through the BESCA Vent Hygiene Elite portal.

Multi-site and managed buildings
Running several sites is easier with one contractor. We work across London and the South East, so a run of sites can go into one programme and kept to a regular schedule.
Managing agents often deal with us directly. Tell us the site, the work and the access arrangements, and we will send a fixed quote.
Common questions in Offham
Can you do ventilation duct cleaning in Offham?
Yes. Our area runs across London and the South East, Offham included. You can call 0345 646 2711 or email us and let us know what needs doing.
Can you get to a site in Offham?
Yes, Offham is part of our area, however small the site. Just mention lanes, gates or anything else about the site when you book.
How often should ventilation ductwork be cleaned?
Under TR19® Air, the answer comes from inspecting the ducts. Busy or sensitive buildings may need it more often.
Can you quote from pictures?
Yes, for many jobs. Send wide shots, close-ups of any access panels and anything that worries you, and we normally come back within one working day. Some sites still need a visit, and we’ll say so.
Do we need to close while you work?
Not usually. Booking the work out of hours means the site can carry on as normal. Larger jobs can be phased over several visits so parts stay in use.
What is TR19® Air?
The two cover different systems: general ventilation for TR19® Air and kitchen extract for TR19® Grease. TR19® Air takes an inspection-led, risk-based approach.
How do you deal with ducts you cannot get into?
Nothing is hidden: any section we couldn’t get into is listed. Access panels can be added where necessary.
Do you have a 24/7 line?
Yes. There’s a 24/7 emergency line for anything that cannot wait until a planned visit. Call us any time and explain what’s happened.
Offham buildings and their air
The nearest hospital to Offham is Lewes Victoria Hospital, about 1.2 miles south. Healthcare buildings depend on clean supply and extract ventilation, and the same applies to surgeries, clinics and care homes. About 42 miles out from central London, Offham is part of the South East area we work across. A survey and a fixed quote come first, then the visit at a time that suits you.
If you run an office near Cooksbridge station, its supply ductwork can gather dust for years before anyone looks inside. Classrooms and halls at schools such as Wallands Community Primary School are easiest to work in when pupils are away.

Honest limits
An honest diagnosis matters more to us than a booking, so here’s what this work cannot put right:
- Design problems with the ductwork layout
- Controls and BMS faults that affect the system
- Damaged ductwork beyond cleaning

Parts of the system we cover
- Offices and schools
- Toilet extract systems
- Grilles and diffusers
- Supply ductwork
- Hospitals and care homes
- General extract ductwork
What the work involves, part by part
Grilles and diffusers
Dust marks around grilles can point to dirt further back in the system. The grilles are cleaned and the ducts behind inspected.
Supply ductwork
Supply runs are inspected at set points first before deciding what to clean.
How it works
There are three stages on the day: set-up, the treatment itself and the sign-off. Set-up means sheeting and making equipment safe, and the sign-off is a written report with photos. The middle part takes longest, which takes a shift or two for a small system, longer for a whole building. Somewhere like Offham, lanes, gates and parking are worth mentioning in advance.
- We agree timings that suit the building, including evenings and weekends.
- We open the ductwork through its access panels.
- Before pictures are taken and the ducts cleaned section by section.
- Grilles and diffusers are cleaned and refitted.
- We take after pictures and send the certificate and report.
How to prepare
- Move anything stored near the system
- Plan for cooking equipment or plant to be off before we arrive
- Have your last certificate or report to hand
Getting a quote
To help us quote: where the site is, what it is and its opening hours, a few photos and the last certificate or report, if there is one. Once you have those, ring 0345 646 2711, or send details by email.

Common problems we fix in Offham
Filters never catch everything, and that fine dust settles along the supply ducts. Extract ducts pick up dust, fibres and fluff from the rooms they serve.
It’s time to book a visit if you see:
- Musty smells from the ventilation
- Rooms that feel airless when the system runs
- Ventilation that needs a TR19® Air inspection
- Toilet and washroom extracts full of fluff
Healthcare ventilation, from large hospitals like Lewes Victoria Hospital (about 1.2 miles south) to small clinics, depends on clean filters, coils and ducts.
Questions to ask before booking
- If the quote is a fixed price or an estimate
- Proof of insurance
- Whether VAT is included
- What paperwork you get at the end
Aftercare tips
Think of this as the after-treatment advice, in brief:
- Keep vents and grilles clear of shelving and stock
- Book the next inspection on the date the report recommends
- Report dust blowing from grilles straight away
- Keep the TR19 certificate and photo report in the maintenance log
What was cleaned is listed, along with any parts that weren’t accessible, with photos before and after. We’ll suggest where new access panels would help.
Make sure there are enough access panels to inspect and clean the ducts. The worst build-up tends to be where no one can look.
