Landlords, agents and facilities managers
Running several sites is easier with one contractor. We work across London and the South East, so visits at different addresses can be planned together and kept on a regular cycle.
Under the Regulatory Reform (Fire Safety) Order 2005, the responsible person must assess and reduce fire risk, which may be the employer, owner, landlord, FM or managing agent. Where responsibility is shared, records matter even more.
Common questions in Bernards Heath
Can a school’s ventilation in Bernards Heath be done out of term time?
Yes, holiday work suits schools best. The FSA’s register shows about 15 schools and colleges with food registrations within roughly a mile and a half of Bernards Heath. Booking early in the term gives the best choice of holiday dates.
Do you work in villages like Bernards Heath?
Yes, we work in villages as well as towns, and Bernards Heath is covered. Let us know about access, parking and anything unusual about getting there when you book.
Are you insured?
Yes. Duct Doctor is fully insured, and the details are available on request.
When should our ventilation next be cleaned?
TR19® Air is risk-based, so cleaning follows inspection rather than a fixed calendar. We suggest a next inspection date after each visit.
Are you accredited?
Our accreditations are CHAS, SafeContractor and ISO 9001, alongside BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease. The Vent Hygiene Elite scheme is run by BESCA and audited independently.
Do you offer maintenance contracts?
Yes. Plans on a 3, 6 or 12-monthly cycle are available, depending on what the system needs.
How long does ventilation cleaning take?
As a guide, it takes from one overnight visit to a phased programme over several weeks. Large buildings can be phased, often out of hours, and we will confirm the plan when we quote.
Can you clean ventilation out of hours?
Yes. We fit the work around when the building is in use. Holidays suit schools, and evenings or weekends suit offices.
What happens on the day
Each visit runs to the same pattern: sheeting and protection first, isolate whatever needs isolating, carry out the ventilation duct cleaning, clear away and leave you the report. The visit itself takes anything from a single shift for a small office to a planned programme of nights for a large building. Getting to the system matters more than parking in a place like Bernards Heath, so let us know how to reach it.
- First we plan when the work can happen, often out of hours.
- Access panels are opened along each run.
- Before pictures are taken and the ducts cleaned section by section.
- Grilles and diffusers are cleaned and refitted.
- After photos are taken and the certificate and report issued.
Preparing for the visit
- Let us know how we reach the system, including roofs, risers and plant rooms
- Find the previous report, if there is one
- Mention any parking or loading restrictions

What the work covers
- Grilles and diffusers
- Offices and schools
- Toilet extract systems
- Hospitals and care homes
- Supply ductwork
- General extract ductwork
Between visits
No system stays clean for ever, but care slows the build-up. Our tips:
- Don’t run the ventilation while builders are sanding or cutting
- Keep vents and grilles clear of shelving and stock
- File each ventilation report with the building records
- Keep to the inspection interval in your report
The report includes a recommended date for the next inspection, in line with the risk-based approach of TR19® Air. Put it in the diary now so it is not missed.
Good filter maintenance protects the ductwork. Overdue or badly fitted filters let dust into the supply ducts.

Staff cleaning versus specialist work
Away from the kitchen, the in-house job is mainly checking: keeping grilles clear, noting unusual noise or smells and logging filter changes. Cleaning inside ducts and units is specialist work.
When your team notices a problem between visits, like drips, unusual noise, smells or damaged filters, they should report it rather than try to fix it. We can diagnose it and quote.
