In-house cleaning or a specialist?
Some jobs should never be done in-house: entering ducts, working on fans, testing dampers and taking grease readings need training, the right equipment and safe access. That’s our job.
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.
About our ventilation duct cleaning in Bygrave
When the work is finished, you get a TR19® certificate and before and after pictures. It shows what was cleaned, anything we couldn’t reach and when the system should next be inspected, giving the ventilation a clean bill of health on paper. The work covers general extract ductwork, grilles and diffusers and supply ductwork, and the jobs we see most are odours carried round the building by the ducts and ductwork that hasn’t been inspected.
In rural areas, ventilation units are often in roof voids or outbuildings, where filters and drain trays get forgotten.
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.

What else we do in Bygrave
Why it’s worth doing now in Bygrave
Clean ducts let the air move as designed, which takes strain off the fans. Leaving them means the plant works harder for the same result. Systems in rural buildings are often out of sight and out of mind.
A single site or a whole portfolio, the quote is built the same way: the work involved, the access and the timing. The price is fixed before work begins.

Questions from Bygrave
Can you get to a site in Bygrave?
Yes. Bygrave 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.
Is ventilation duct cleaning available in Bygrave?
Yes. Our area runs across London and the South East, Bygrave included. You can ring 0345 646 2711 or drop us a line and tell us what needs doing.
Do we lose a day’s trading?
Not typically. We work when the area is out of use, such as evenings, overnight, early mornings or weekends, so you keep your normal hours.
Do you have a 24/7 line?
Yes, day and night, every day of the year. Our office is open from 8am to 6pm on weekdays, with the emergency line covering every other hour.
How much time does a ventilation clean need?
Typically, the work takes anything from a single shift for a small office to a planned programme of nights for a large building. Large buildings can be phased, often out of hours, to fit around the building.
Which kinds of sites do you work on?
We work for restaurants, pubs, hotels, schools, colleges, hospitals, care homes, offices and shops, plus food production and leisure sites.
What do you do to protect the area?
Floors and surfaces near the work are sheeted before work begins, and anything we remove is contained. Before we leave, we tidy up and clean down.
Do we get a certificate after the clean?
Yes, both a certificate and a photo report. The report lists what was cleaned, anything not reached and the next inspection date.
When something else is needed
We’d rather tell you now than book work that will not help, so these are the things it will not cover:
- Controls and BMS faults that affect the system
- Damp or mould problems coming from the building fabric
- Leaking or broken duct sections
Not sure which it is? You can give us a ring on 0345 646 2711, or send details by email and we’ll tell you honestly.
Parts of the system we cover

How the visit works
We turn up at the time agreed with you, often in the evening, overnight or at the weekend so the site keeps working. Anything that needs to be off for the work is switched off and left to cool before any work starts, and the area around the work is covered and protected. The work itself takes anything from a single shift for a small office to a planned programme of nights for a large building. Somewhere as small as Bygrave, the date and timings are agreed with you well before the day.
- We survey the system from drawings, pictures or a site visit.
- We inspect inside the ductwork at set points and photograph it.
- We protect the rooms beneath and switch the system off.
- We clean the ductwork, grilles and diffusers through access panels.
- We issue a TR19® certificate and a photo report listing what was cleaned.
Before we arrive
- Make sure equipment near the work can be switched off and left to cool
- Clear loose items from the work area
- Mention any sign-in, permit or induction we need
Ask for a quote
Photos are the quickest way to a quote: wide shots of the system, close-ups of anything that worries you and how we’d get to it. Tell us what kind of site it is and when it’s open, and we can price many jobs without a visit.

Different parts, different methods
Supply ductwork
Supply ductwork delivers conditioned air to each room. Fine dust that gets past the filters settles along the runs, and it’s cleaned out through access panels.
Hospitals and care homes
In care settings, keeping dust contained is a priority. The area is protected, and debris contained and removed.
Common problems we fix in Bygrave
Most ductwork is out of sight, so nobody sees the build-up. Grilles may be wiped, but the ducts behind them rarely are.
The symptoms we’re asked about most are:
- Poor airflow from the vents
- Blocked general extract ductwork
- Ductwork with too few access panels to clean
- Ventilation full of debris from building work
For schools like The Knights Templar School, the holidays are the usual time to inspect and clean ventilation.

Landlords, agents and facilities managers
Records are where multi-site compliance often slips. Each visit produces a dated report with photos, ready to show insurers, fire officers or EHOs.
We work for landlords, managing agents and facilities managers as well as the people running the site. Shared systems, like a riser serving several units, need a clear agreement on who books the work, and we can quote for the whole system.
