Ventilation duct cleaning for kitchens and businesses in Goff's Oak
We always start by inspecting. The ducts are opened at access points and the condition recorded, then recommend cleaning where it’s needed. That way the work matches the real condition. Common call-outs are for ductwork with too few access panels to clean and damp or stale smells from grilles, across general extract ductwork, supply ductwork and offices and schools.
Visits to a place like Goff's Oak are fitted around opening hours. The method does not change: inspect first, clean, then record what was done.
For insurers and inspectors, the record counts. That is why every job is written up in a report with photos, and grease extract cleans come with a TR19® certificate issued through the BESCA Vent Hygiene Elite portal.

The process
A visit follows the same order every time: sheeting and protection first, make the system safe, do the work, clear away and leave you the report. On site, the work takes from one overnight visit to a phased programme over several weeks. For a place like Goff's Oak, we load the van from the survey notes so the work can be done in one visit where possible.
- We look at the system and any earlier reports.
- Inspection points are chosen and the ducts examined.
- The work area is protected and the system switched off.
- Ducts, grilles and diffusers are cleaned and the debris taken away.
- The report records what was cleaned, anything not reached and a next inspection date.
Before we arrive
- Clear loose items from the work area
- Mention any sign-in, permit or induction we need
- Agree a time when the area can be out of use
Ask for a quote
Quotes are quick. Call or email with a few details and you’ll normally have a fixed price within one working day. If we need to see the system first, we book a survey around your hours.
Related advice
Part by part
Grilles and diffusers
Dark streaks round a ceiling diffuser can be a sign of dirty supply air. The grilles are cleaned and the ducts behind inspected.
Hospitals and care homes
People in hospitals and care homes can be more vulnerable to poor air. Inspection-led cleaning under TR19® Air helps keep systems in good condition.
Aftercare tips
Here’s the after-treatment advice, in brief:
- Watch for water stains around grilles
- Include grilles in the cleaning rota
- Switch the ventilation off or cover grilles during dusty building work
- Tell your facilities team about dirty diffusers
We recommend when the system should next be inspected, based on what we found. Put it in the diary now so it isn’t missed.
Fit access panels where the ductwork cannot be reached. The worst build-up tends to be where no one can look.
Fixed quotes for ventilation duct cleaning in Goff's Oak
There’s no set price list, because sites vary so much. What we look at:
- Whether it’s a one-off visit or part of a schedule
- Travel, parking and unloading
- When the work can happen, such as evenings, overnight or weekends
- Any permits to work or inductions
When the work has to happen, how we reach it and how big the site is all affect the cost. We take each of them into account and give you a fixed price before we start.
Asking for a quote
To speed up the quote, send us:
- Wide photos of the system and the area around it
- The paperwork from the last visit, if you have it
- The times we could work without disrupting the site
- Where the plant sits or the system leaves the building, such as a roof or outside wall
Photos are the quickest way to a quote: the system from a couple of angles, plus any access panels or hatches. Tell us what kind of site it is and when it’s open, and many jobs can be priced from that alone.

Leave it or put it right?
Leave dust in the ductwork and it keeps building. The longer it’s left, the more there is to remove, and the more gets blown back into the rooms. Booking now means the visit to Goff's Oak is planned around you, not forced by a breakdown.
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 not sure what’s needed, ring 0345 646 2711, or send details by email and we will give you an honest view and a fixed quote.

Common problems we fix in Goff's Oak
Building work is one of the biggest sources of debris in ducts, especially when the system runs during the work. That dust can stay in the ducts long after the builders leave.
Any of these means the system needs a check-up:
- Construction dust left in ducts after a refit
- Dusty supply ductwork that hasn’t been cleaned in years
- Odours carried round the building by the ducts
- Rooms that feel airless when the system runs
For schools like Woodside Primary School, the holidays are the usual time to inspect and clean ventilation.

FAQs for Goff's Oak
Will you come out to Goff's Oak?
Yes. Goff's Oak is within the area we cover across London and the South East. Photos of the system and directions to the site help us plan the visit.
Do you work at weekends in Goff's Oak?
Yes, we can come after you close and finish before you open. It means the site in Goff's Oak keeps running as normal. When you call 0345 646 2711 or use the quote form, mention when the site is quiet.
How much time does a ventilation clean need?
As a guide, it takes from one overnight visit to a phased programme over several weeks. Bigger sites are split into stages, and we’ll confirm the plan when we quote.
Which sectors do you work in?
Any commercial site with kitchens or ventilation, from a single café to a large school. Hotels, schools, care homes, offices, shops and leisure sites are all part of our work.
How does TR19 Air differ from TR19 Grease?
TR19® Air applies to the general ventilation in buildings like offices, schools and hospitals. Kitchen extract is covered separately, by TR19® Grease.
Does the law say we must follow TR19?
No. TR19® is BESA’s specification, not legislation. The legal duty comes from the Regulatory Reform (Fire Safety) Order 2005: the responsible person must assess and reduce fire risk, and TR19® is the benchmark for showing that grease in the extract is under control.
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 happens to the waste?
Waste is contained during the work and removed when we leave, from grease and debris to used cleaning water. None of it is left on site.
