Aftercare tips
Simple habits between visits make a real difference. Our advice:
- Stick to the filter change schedule
- Keep the TR19 certificate and photo report in the maintenance log
- Diary the next TR19® Air inspection
- Make sure nothing is stacked against extract grilles
Keep up with filter changes to protect the ducts. Overdue filters let dust straight back in.
Regular inspection is the core of TR19® Air. Inspecting on a schedule catches build-up before it becomes a big clean.
How we handle ventilation duct cleaning in Bishopsgate
Ventilation duct cleaning is something we carry out for buildings in Bishopsgate and right across Surrey, from offices and schools to hospitals, care homes and shops. Each building gets a survey first and a fixed quote. Common call-outs are for odours carried round the building by the ducts and dirty diffusers dropping dust into rooms, on hospitals and care homes, toilet extract systems and offices and schools.
Rural buildings with mechanical ventilation, such as care homes and country hotels, often keep their units in roof spaces or outbuildings, where filters and drain trays get forgotten.
Insurers, fire officers and environmental health officers all look at records. That’s why every job is written up in a report with photos, plus a TR19® certificate through the BESCA VHE portal where the work is a TR19® Grease clean.

Bishopsgate: your questions answered
Can ventilation in schools around Bishopsgate be cleaned out of term?
Yes. The holidays are the usual time for school work. With about 17 schools and colleges on the FSA’s register within roughly a mile and a half of Bishopsgate, it pays to plan holiday dates ahead. Just ring 0345 646 2711 or use the quote form with your term dates and we’ll plan around them.
Do you work in villages like Bishopsgate?
Yes, we work in villages as well as towns, and Bishopsgate is covered. A survey first, from photos or a visit, means we arrive with the right kit.
How much time does a ventilation clean need?
It takes a weekend for a modest system, with large buildings phased floor by floor. How much ductwork there is and how easily it’s reached decide the rest.
Do you offer maintenance contracts?
Yes. Plans on a 3, 6 or 12-monthly cycle are available, to suit the system and how it’s used.
What information do you need?
Just the basics: the address, the site type, your opening hours and how we reach the system. Photos and the last report help too. Then call us on 0345 646 2711, or email photos.
Can one contract cover all our sites?
Yes. You deal with one contact for every site across London and the South East, with visits on a regular schedule.
Is there a survey before the work?
Yes, always. We diagnose before we treat: the survey shows what needs doing and what access we need and the fixed quote is built on it.
Which accreditations do you hold?
Duct Doctor is a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we’re fully insured.
How it works
On the day, we arrive at the time agreed with you, often in the evening, overnight or at the weekend so the site keeps working. Equipment that has to be off is switched off and allowed to cool first, and the area around the work is covered and protected. The work itself takes a day or less for a small system and a series of visits for a large one. For a village or hamlet like Bishopsgate, tell us about narrow lanes, gates and parking when you book.
- 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.
- We report on the work, listing any inaccessible sections and the next inspection date.
Before we arrive
- Find the previous report, if there is one
- Mention any sign-in, permit or induction we need
- Agree a time when the area can be out of use
Get a fixed quote
Some systems can be priced from pictures; others need a survey. Larger sites, and anything hidden behind walls, ceilings or floors, are normally surveyed first. Either way, the quote is fixed before any work is booked.

Why act early in Bishopsgate
Landlords, tenants and auditors may want proof the ventilation is looked after. Having a recent certificate and photo report for a building in Bishopsgate answers the question. Somewhere as small as Bishopsgate, losing a kitchen or building to a fault is felt by everyone who uses it.
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 the price is fixed before we start.

What ventilation duct cleaning looks like in Bishopsgate
Food Standards Agency data includes about 17 schools, colleges and universities and about 6 hospitals, care homes and childcare premises in Bishopsgate and the streets around it, up to about 1.5 miles out. Busy, occupied buildings like these are where clean supply air matters most. King Edward VII Hospital is the nearest hospital, about 2.7 miles north-west of Bishopsgate. Healthcare ventilation is a good example of why supply ducts need inspecting: the air goes straight to patients. We cover Bishopsgate, about 22 miles from central London, as part of our work across London and the South East. The visit is fixed around your opening hours, not ours.
Hospitals such as King Edward VII Hospital (about 2.7 miles north-west) show how much a building can rely on clean ventilation, and smaller healthcare sites near Bishopsgate are no different. Wherever a school like St John's Beaumont School has ducted ventilation, a half-term visit keeps the work out of lesson time.

For landlords and multi-site operators
Landlords, managing agents and facilities managers book us, not only the businesses that use the systems. Shared systems, like a riser serving several units, need a clear agreement on who books the work, and we are happy to quote for all of it.
Running several sites is easier with one contractor. We cover South East England and London, so a run of sites can go into one programme and kept on a regular cycle.
Honest limits
Not every problem is solved by ventilation duct cleaning, and we will tell you before we start. It won’t put right:
- Design problems with the ductwork layout
- Building management settings that run the plant
- Damp or mould problems coming from the building fabric
Not sure which it is? You can call 0345 646 2711, or email photos and we’ll tell you honestly before you book.

What affects the quote in Bishopsgate
Sites vary more than people expect. What affects the quote:
- Whether several sites go on one quote
- The condition of the system
- Access, including roofs, risers and ceiling voids
- Travel, parking and unloading
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 we start.
What to send for a quote
What to send for a quote:
- Your opening hours and when the area is out of use
- Wide pictures of the system and the area around it
- The postcode and the type of business
- Detail shots of panels, filters and grilles
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.
What staff can safely do
A few tasks are always specialist work: entering ducts, working on fans, testing dampers and taking grease readings call for the right kit, training and safe access. Leave those to us.
Staff cleaning and specialist work are not the same thing. A daily filter wipe and a weekly filter wash keep grease down at the front of the system, but they do not reach the grease that builds up further in. Reaching it takes a specialist with the right equipment.
