How we handle ventilation duct cleaning in Nether Street
When the work is finished, you get a TR19® certificate and before and after photos. The report lists what we cleaned, any sections not reached and a recommended next inspection, so you have it all on record. The work covers general extract ductwork, offices and schools and grilles and diffusers, and the jobs we see most are dust marks around grilles and ceiling diffusers and ducts that need a clean before handover.
For a building in or near Nether Street, access is agreed in advance and the visit is planned around the journey.
For insurers and inspectors, the record counts. So every job comes with a written report and pictures, plus a TR19® certificate through the BESCA VHE portal where the work is a TR19® Grease clean.

Staff cleaning versus specialist work
Good housekeeping makes our visits easier, not unnecessary. Clean filters and tidy surfaces slow the build-up, but hidden parts of the system still need specialist attention.
In-house cleaning and specialist cleaning do different jobs. Wiping filters daily and washing them weekly keeps the visible parts in order, but they do not reach the grease that builds up further in. Reaching it takes a specialist with the right equipment.
Why deal with it now?
Where a building in Nether Street serves patients, residents or children, putting off ventilation cleaning is hard to justify. Clean ducts are part of providing good air for the people inside. Planning a trip to Nether Street ahead is easier for everyone than a rushed one.
You will not find a price list here, because each job is priced on what it involves. For a fixed quote, call 0345 646 2711, or send details by email, and we’ll explain what it covers.

When to call us in Nether Street
Planned maintenance tends to focus on fans and filters, not the ducts. Plant can be well serviced while the ductwork goes untouched for years.
These are the problems we see most often:
- Ductwork never cleaned since it was installed
- Blocked general extract ductwork
- Systems with no record of inspection or cleaning
- Ductwork with too few access panels to clean
For schools like Widford School, the holidays are the usual time to inspect and clean ventilation.

Advice
Nether Street: your questions answered
Can you work in Nether Street outside opening hours?
Yes, out-of-hours work is a big part of what we do. The site is handed back ready to open. Your opening times are the first thing we ask for.
Can ventilation in schools around Nether Street be cleaned out of term?
Yes, out-of-term visits are normal for schools. Around Nether Street, the Food Standards Agency lists about 2 schools and colleges with registered kitchens within a mile and a half or so. Booking early in the term gives the best choice of holiday dates.
How does TR19 Air differ from TR19 Grease?
It covers ventilation hygiene for supply and extract systems in offices, schools, hospitals and other buildings. Kitchen extract systems fall under TR19® Grease instead.
Can you come out in an emergency?
Yes, 24/7. Our office is open from 8am to 6pm on weekdays, and the emergency line covers the rest.
Do you survey before quoting?
Yes. Every job is surveyed first, from your pictures and details, or with a visit where necessary. A fixed quote follows.
Will we have paperwork to show the system was cleaned?
Yes. Every clean comes with a TR19® certificate and a photo report. BESA advises keeping certificates in the maintenance log.
Is a quote from photos possible?
Yes, if we can see what we need. Otherwise, we book a survey at a time that suits the site, then a fixed quote.
Which kinds of sites do you work on?
Commercial premises of every kind: kitchens, offices, schools, healthcare, retail, leisure and food production. Work is timed around how each site runs.
Landlords, agents and facilities managers
For anyone managing more than one site, we can plan visits across the whole estate and price them together. Every building has its own written report, so each one has its own record.
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.
What affects the quote in Nether Street
Sites vary more than people expect. What affects the quote:
- Working hours and out-of-hours timing
- Travel, parking and unloading
- The size of the system
- One-off work versus a regular cycle
Leaving it longer rarely makes the work cheaper. Problems in a system tend to grow, which can make the next visit longer. If you’re not sure what’s needed, call us on 0345 646 2711, or send details by email for straight advice and a fixed quote.
What we need to know
We can often survey from pictures. Try to include:
- The postcode and the type of business
- Close-ups of filters, grilles, hatches or access panels
- The roof, plant room or outside wall the system runs to
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
The quickest way to a quote is to send photos: 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.
