About our AHU cleaning in Lake End
Our AHU cleans for sites in Lake End cover the parts that collect dirt: the filter section, heating and cooling coils, drain trays, fan and casing. You get a TR19® certificate and a photo report showing the unit before and after. If you are dealing with units needing a clean before a new tenant or handover and intake sections clogged with outdoor debris, we can help, from drain trays, internal panels and filter sections onwards.
Somewhere as small as Lake End, ducted ventilation is typically limited to a school, a care home, a surgery or a converted business building, wherever there is one, but those that do need it inspected and cleaned like any other.
Duct Doctor has been trading since 2009, as a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. CHAS, SafeContractor and ISO 9001 are in place too, and we’re fully insured.

What happens on the day
On the day, we arrive at the time agreed with you, which is often after service, overnight or at a weekend. Anything that needs to be off for the work is switched off and left to cool first, and floors and nearby surfaces are sheeted. On site, it takes half a day to a full day per unit, with large plant planned over several shifts. If you can send photos, we can arrive in Lake End knowing what to expect.
- First we agree when the unit can be switched off, including evenings or weekends.
- Before cleaning, each section is photographed.
- We work through the unit from the intake to the outlet.
- The fan and drain tray are cleaned and the drain checked.
- We take after photos and issue the certificate and report.
Before we arrive
- Let us know when the site is closed or quiet
- Tell us where we can park and unload
- Let us know how we reach the system, including roofs, risers and plant rooms

Aftercare tips
Looking after the system between visits is straightforward, and it helps at the next visit:
- Note any water around the unit or leaks below it
- Do not ignore odours coming through the grilles
- Keep filter changes on time and recorded
- Make sure condensate is draining away
The report shows each section of the unit before and after, along with anything we couldn’t reach. Any defects we noticed, like a leaking tray or damaged lining, are listed.
Make sure access doors and panels on the unit open easily. Sections that are awkward to open are the ones that get skipped.

Rooftop and plant room units
Units on roofs and in plant rooms can be awkward to reach. Access is planned during the survey so the quote reflects it.
Heating and cooling coils
Heating and cooling coils have tightly packed fins that trap fine dust. They’re cleaned using methods that won’t bend or flatten the fins.
AHU cleaning around Lake End
Food Standards Agency records list about 7 schools, colleges and universities, about 14 care, childcare and hospital premises and about 3 hotels, B&Bs and guest houses registered as food businesses in Lake End and the streets around it, up to about 1.5 miles out. Classrooms, bedrooms and care spaces are often served by ducted air, and that ductwork collects dust over time. Lake End’s nearest hospital, Upton Hospital, is about 3 miles east. Healthcare ventilation is a good example of why supply ducts need inspecting: the air goes straight to patients. Lake End is about 24 miles from central London, well within the area we cover across London and the South East. Evening, overnight and weekend visits are all possible.
Hospitals such as Upton Hospital (about 3 miles east) show how much a building can rely on clean ventilation, and smaller healthcare sites near Lake End are no different.

Lake End: your questions answered
Do you work in villages like Lake End?
Yes, we work in villages as well as towns, and Lake End is covered. Just mention lanes, gates or anything else about the site when you book.
Can a school’s ventilation in Lake End be done out of term time?
Yes. Half-terms and the summer break are the natural time for school work. With about 7 schools and colleges on the FSA’s register within roughly a mile and a half of Lake End, it pays to plan holiday dates ahead. Just call 0345 646 2711 or drop us a line with your term dates and we’ll plan around them.
Is there a report after cleaning?
Yes. Every clean comes with a TR19® certificate and a photo report. Keep them in the maintenance log.
How far ahead should we book?
That depends on the slot you want and the size of the job. Mention your preferred dates with your enquiry, and if it’s an emergency, call us any time.
What is TR19?
A BESA specification, with two parts that matter most here: TR19® Grease for kitchen extract systems and TR19® Air for general ventilation. It is not legislation, but it’s the standard people check against.
When should our AHU next be cleaned?
TR19® Air takes a risk-based approach, so it depends on inspection rather than a fixed interval. Each report suggests when the unit should next be looked at.
How do you keep the site clean during the work?
By covering it before any work starts. We keep the work contained and clean down when we finish.
Where does the waste go?
We take it away when we go. During the work, it’s contained to keep the area clean.
Multi-site and managed buildings
Running several sites is easier with one contractor. We cover South East England and London, so visits at different addresses can be planned together and kept on a regular cycle.
Records are where multi-site compliance often slips. Each visit produces a dated report with pictures, ready to show insurers, fire officers or EHOs.
Why act early in Lake End
A light clean now is simpler than a heavy one later. Leave it for years and dirt bakes onto coils and casings, especially where there’s been moisture. In a small place like Lake End, a system that fails can take a site out of use.
Several systems or sites on one quote can make for a more efficient booking. Tell us about everything you’d like looked at and we’ll price it together.

What affects the cost of AHU cleaning
There’s no set price list, because sites vary so much. What we look at:
- The times the site is available
- Whether several sites go on one quote
- Where the site is and how we reach it
- The condition we find in the survey
No two sites are the same, so each one gets its own fixed quote. Size, access, the condition of the system and when we can work all play a part.
Helping us quote
We can often survey from pictures. The most useful are:
- How we’d reach plant on a roof or in a plant room
- The site address and the type of premises
- A few general shots of the system
- The paperwork from the last visit, if you have it
Quoting starts with a diagnosis, from your photos and details or, where that isn’t enough, a survey on site. After that, you get a fixed price for the work, before we start.
Signs you need AHU cleaning in Lake End
Filters that are not changed or cleaned on time clog up, which cuts the airflow and can let air slip round the filter. After that, the coils and fan collect what the filter should have caught.
Look out for these warning signs:
- Dust-coated heating and cooling coils
- Plant that has been serviced but not cleaned
- Units needing a clean before a new tenant or handover
- Stale or musty smells from the ventilation
If you manage a school such as Cippenham Infant School, ventilation cleaning is best booked for the holidays.
Questions to ask before booking
- Whether the quote is based on a survey or photos
- What records you will receive afterwards
- Which accreditations they hold, and whether you can check them
- Whether they’re fully insured
