Why deal with it now?
If a building in Longlands has just been refitted, now is the time to clean the ductwork. Otherwise the dust from the works comes out of the grilles once it’s switched back on. Every month a London system goes without attention adds to what has to be done later.
The cost depends on how big the system is, the condition it’s in and how easy it is to reach. We give you a fixed price before we start, so there are no surprises.

How we handle ventilation duct cleaning in Longlands
In a building in Longlands, the people inside spend hours breathing what the ventilation delivers. Clean ducts are part of a healthy building, as much as clean filters and a well-kept AHU. If you’re dealing with stuffy rooms and stale air and ventilation full of debris from building work, we can help, from supply ductwork, offices and schools and toilet extract systems onwards.
Many London buildings have had their ventilation extended and altered through several fit-outs, leaving sections that are hard to reach and seldom cleaned. An inspection first shows where cleaning is needed in a building in Longlands.
Nothing is signed off by word of mouth: a dated report with photos of the work, and for TR19® Grease cleans, a certificate issued through the BESCA VHE portal. It shows what was done and what, if anything, couldn’t be reached.

Fixed quotes for ventilation duct cleaning in Longlands
The survey tells us what the work involves. We look at:
- Whether we need access equipment or extra panels
- The times the site is available
- The condition of the system
- How many systems or sites are involved
Putting the work off seldom saves money. Build-up, wear and faults tend to get worse, not better, which can make the next visit longer. If you are unsure, ring 0345 646 2711, or send details by email and we’ll give you an honest view and a fixed quote.
Helping us quote
Before you ask for a quote, gather:
- The postcode and the type of business
- The times we could work without disrupting the site
- A few general shots of the system
- Any previous report or certificate
There’s no standard price list, because every site is different. Instead, we look at your site first, from pictures or a survey, and then send you a fixed quote. To get going, give us a ring on 0345 646 2711 or send us an email.
Between visits
Aftercare is simple, and it helps at the next visit:
- Store cleaning certificates where auditors can find them
- Report dust blowing from grilles straight away
- Keep filters changed on time
- Wipe grilles and diffusers during routine cleaning
Pass the paperwork to your facilities or maintenance team, so it’s all in one place. Year on year, it shows how fast dust builds up.
Fit access panels where the ductwork can’t be reached. Hidden sections are the ones that get worst.
How the visit works
When we arrive, we check the system against the survey or the pictures you sent. If anything is different, we talk it through with the person on site before carrying on. After that, the work takes anything from a single shift for a small office to a planned programme of nights for a large building. In Longlands, as across London, we usually work overnight or at weekends and hand the site back ready to open.
- First we check the layout and any past paperwork.
- Inspection points are chosen and the ducts examined.
- The work area is protected and the system switched off.
- We clean the system and remove the debris from site.
- The report records what was cleaned, anything not reached and a next inspection date.
Getting ready for the visit
- Make sure equipment near the work can be switched off and left to cool
- Name a contact who can let us in at the agreed time
- Dig out any earlier paperwork for the system

Questions from Longlands
Is parking a problem for work in Longlands?
Tell us where a van can stop near your site in Longlands, and about any building rules on loading. Working overnight, as we often do in London, typically makes it simpler.
Can you work in Longlands outside opening hours?
Yes, evening, overnight and weekend work is normal for us. It means the site in Longlands keeps running as normal. Let us know the hours you are closed and we will book within them.
Are you accredited?
We hold CHAS, SafeContractor and ISO 9001, and we are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. Vent Hygiene Elite is run by BESCA and independently audited.
What types of premises do you cover?
We work for restaurants, pubs, hotels, schools, colleges, hospitals, care homes, offices and shops, plus food production and leisure sites.

Will we have paperwork to show the system was cleaned?
Yes, a TR19® certificate and photos. It also notes unreached sections and a recommended next inspection.
How long does ventilation cleaning take?
Work on site takes a weekend for a modest system, with large buildings phased floor by floor. We will know more after the survey, and you can give us a ring on 0345 646 2711, or send details by email to arrange it.
How much does ventilation duct cleaning cost?
We don’t publish prices, because the cost depends on the job: how big it is, what state it’s in, how we reach it and the working hours. We fix the price before any work starts.
Staff cleaning versus specialist work
In-house cleaning and specialist cleaning do different jobs. 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.
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, which is where we come in.
