Wanstead questions
Do you do school ventilation cleaning in Wanstead in the summer holidays?
Yes. Half-terms and the summer break are the natural time for school work. There are about 32 schools, colleges and universities on the FSA’s food hygiene register within about 1.5 miles of Wanstead. Just call 0345 646 2711 or drop us a line with your term dates and we’ll plan around them.
Is parking a problem for work in Wanstead?
We plan it in advance, so let us know about loading bays, permits and access rules at the building. Working overnight, as we often do in London, normally makes it simpler.
Are you insured?
Yes. We carry full insurance, and we’ve been trading since 2009.
Which sectors do you work in?
We work for restaurants, pubs, hotels, schools, colleges, hospitals, care homes, offices and shops, as well as food production and leisure sites.
When should our AHU next be cleaned?
There’s no single answer; it comes down to the building and the unit. Inspection tells you when cleaning is needed, and we will suggest an interval after the first clean.
Can you set up regular visits?
Yes. We run scheduled maintenance contracts, with visits at the interval your system needs. Each report recommends when the next visit should be.
Can you fix a faulty AHU?
Motors, belts, controls and coils that need repair are a job for your maintenance contractor. We will flag anything we notice during the clean.
How much notice should we give?
For planned work, earlier is better, especially if the next clean or test is due soon. For emergencies, we take calls 24/7.
How we handle AHU cleaning in Wanstead
Think of an AHU clean as a full check-up for the ventilation. Every section is opened, cleaned and photographed, so the report shows exactly what was done. The work covers dampers and louvres, heating and cooling coils and supply and extract fans, and common reasons people get in touch are plant that needs cleaning after a refit and air handling units with blocked filters.
Many London buildings have had their ventilation extended and altered through several fit-outs, leaving sections that are hard to reach and seldom cleaned. An inspection first shows where cleaning is needed in a building in Wanstead.
Think of the report as the system’s health record: dated, with photos, and showing what was done. Grease extract cleans are also certificated to TR19® Grease through the BESCA VHE portal, ready for your insurer.

Keeping the system healthy
To keep the system working properly between visits:
- Plan the next inspection before the last report gets filed away
- Keep inspection doors on the unit in good order
- Keep the certificate and photo report with the plant records
- Keep filter changes on time and recorded
If the ductwork hasn’t been cleaned, consider it next. A clean unit feeding dirty ducts only solves half the problem, and we can survey both.
Have the unit inspected regularly, in line with the risk-based approach of TR19® Air instead of leaving it to guesswork.
For landlords and multi-site operators
We work for landlords, managing agents and facilities managers as well as the people running the site. Where a system serves more than one tenant, such as a shared riser, it helps to agree who arranges the work, and we’re happy to quote for all of it.
The Fire Safety Order 2005 puts the duty to manage fire risk on the responsible person, which may be the employer, owner, landlord, FM or managing agent. With shared responsibility, good records help everyone.
Why deal with it now?
Stuffy rooms and stale smells in a building in Wanstead can sometimes be traced back to the AHU. Cleaning it deals with the cause rather than the symptom. In a London building, a problem in a duct, damper or fan rarely stays in one unit.
The price reflects the work, not guesswork. That’s why we survey first, from photos or on site, and the price is agreed before any work starts.

What affects the cost of AHU cleaning
Every site gets its own quote. This is what makes a difference:
- Where the site is and how we reach it
- How many systems or sites are involved
- The scale of the work
- What state the system is in
Leaving it longer rarely makes the work cheaper. Build-up, wear and faults tend to get worse, not better, and a neglected system can mean more work. If you’re not sure what’s needed, call 0345 646 2711, or send details by email and we will give you an honest view and a fixed quote.
What to send for a quote
Many jobs can be priced from pictures and some basics. Useful things to send:
- Any previous report or certificate
- Wide pictures of the system and the area around it
- Where the site is and what kind of site it is
- Any symptoms, from odd noises to smells or leaks
Some systems can be priced from pictures; others need a survey. Big or complicated sites, and systems that are hard to see in photos, get a survey first. Either way, you get a fixed price before work begins.
Do you need AHU cleaning in Wanstead?
Filters that are not changed or cleaned on time clog up, cutting airflow and sometimes letting dirty air bypass them altogether. Then the rest of the unit takes the load.
What we’re most often called out for:
- Filters that are clogged or overdue
- Drain trays holding standing water
- Debris and leaves in the fresh air intake
- Units needing a clean before a new tenant or handover
Hospitals such as Wanstead Hospital (about 0.5 miles north) show how much a building can rely on clean ventilation, and smaller healthcare sites near Wanstead are no different.
What your quote should include
- How they set the interval to the next visit
- If the quote is a fixed price or an estimate
- What hours they’ll be on site
- What records you will receive afterwards
In-house cleaning or a specialist?
Logging matters as much as cleaning. A simple log of filter washes, wipe-downs and checks shows an inspector that the system is looked after between visits, alongside our reports.
Away from the kitchen, the in-house job is mainly checking: keeping grilles clear, noting unusual noise or smells and logging filter changes. The inside of ducts and units needs a specialist.
What happens on the day
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 before we start, and the area around the work is covered and protected. On site, it takes one overnight shift for many single units, with bigger plant phased. For a job in Wanstead, tell us about loading bays, permits, lifts and roof access when you book.
- 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.
- We finish with the fan section and the drain tray.
- We take after pictures and issue the certificate and report.
Getting ready for the visit
- Tell us about site rules, permits or sign-in
- Let us know about parking and loading
- Tell us the best time to work, such as after service or at a weekend
