AHU cleaning in Seven Kings

About our AHU cleaning in Seven Kings

A cooling coil drips condensate into a tray that should drain away. When the drain blocks, water sits there and the tray turns slimy, in the airstream that feeds the building. Clearing and cleaning the tray is central to every AHU clean. If you have stale or musty smells from the ventilation and dirty coils holding back the airflow, we can help.

Across London, offices, hotels, schools and healthcare buildings rely on mechanical ventilation, much of it supplied through air handling units on roofs or in basements. In a building in Seven Kings, dust and debris build up in the units and ductwork over time.

Nothing is signed off by word of mouth: a dated report with pictures of the work, plus a certificate through the BESCA Vent Hygiene Elite portal when the work is a TR19® Grease clean. It shows what was done and what, if anything, couldn’t be reached.

Managing agents and facilities teams in Seven Kings

Multi-site operators often want one contractor and one number. We cover South East England and London, so a run of sites can go into one programme and kept to a regular schedule.

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 can quote for the whole system.

Why deal with it now?

A clean unit feeds cleaner air into the ductwork, so the ducts and grilles stay cleaner between cleans. That makes the next inspection of a building in Seven Kings simpler. Every month a London system goes without attention adds to what has to be done later.

Leaving it longer rarely makes the work cheaper. Problems in a system tend to grow, and a neglected system can mean more work. If you are unsure, phone us on 0345 646 2711 or drop us a line for straight advice and a fixed quote.

What you get with us

  • Every job surveyed first
  • Photo reports with every job
  • Fixed quotes from a survey or pictures
  • A single point of contact for sites across the South East and London

Keeping the system healthy

Looking after the system between visits is straightforward, and it makes the next visit easier:

  • Keep the area around the fresh air intake clear
  • Report stiff or damaged access doors
  • Book the next check in line with the report
  • Don’t ignore odours coming through the grilles

Restart the unit with your site team or maintenance contractor once we have finished. Check the drain tray is emptying over the first few days to make sure it stays clear.

Keep the area around the intake clear. Anything around the intake is likely to be drawn in.

How it works

Our technicians bring everything the work needs, from protective sheeting to tools and access equipment. You only need to give us clear access and switch off what needs to be off. On site, the work takes from a few hours for a compact unit to a day or more for a large one. Before any visit in Seven Kings, we agree where the van can stop and how equipment reaches the system.

  1. We survey the unit from photos or on site and agree what’s included.
  2. The unit is shut down with your site team and the area protected.
  3. We clean or change the filters as agreed, then clean the coils, fan and internal panels.
  4. Drain trays are cleared and cleaned and the outlet checked.
  5. A TR19® certificate and photo report follow the clean.

Getting ready for the visit

  • Let us know about permits to work or site inductions
  • Make sure someone can let us in and lock up afterwards
  • Move anything stored near the system

How the job changes from site to site

Fans and fan sections

Dust on a fan impeller adds weight and wear. A clean fan runs more smoothly.

Internal casing and panels

Damaged internal linings or loose panels can shed material into the air. We note any we find in the report.

What staff can safely do

Staff cleaning doesn’t replace a specialist visit; it supports it. Regular in-house cleaning slows the build-up, but hidden parts of the system still need specialist attention.

For ventilation and air handling systems, in-house care is mostly about checks: clear grilles, a log of filter changes and reporting anything odd. The inside of ducts and units needs a specialist.

Seven Kings questions

Can parking be tricky for a job in Seven Kings?

A loading bay, a visitor permit or off-street space near the site in Seven Kings makes the visit easier to plan. Where restrictions apply in the day, an evening or overnight visit usually gets round them.

Do you clean school ventilation in Seven Kings in the holidays?

Yes, and it’s the easiest time to do it. The FSA’s register shows about 49 schools and colleges with food registrations within roughly a mile and a half of Seven Kings. Tell us your holiday dates and we’ll book the visit for when the site is empty.

Do you have a 24/7 line?

Yes. There’s a 24/7 emergency line for anything that can’t wait until a planned visit. Ring any time and tell us what’s happened.

Is there a report after cleaning?

Yes. A TR19® certificate and photo report are sent after the clean, with any faults we noticed.

Can you look after several sites?

Yes. Send the list of sites and the work at each and we will quote them together.

What do you do to protect the area?

We cover floors and nearby surfaces with sheeting before any work starts, and waste is contained as we go. Before we leave, we tidy up and clean down.

How long does an AHU clean take?

Expect it to take anything from half a day for one small unit to several shifts for a plant room full of them. The unit’s size and condition make the biggest difference, and we’ll confirm the time when we quote.

Do you survey before quoting?

Yes, always. We diagnose before we treat: the survey shows what needs doing and what access we need, and the quote is based on that.

What affects the cost of AHU cleaning

The diagnosis comes before the price. We look at:

  • Whether it’s a one-off visit or part of a schedule
  • How easy every part is to reach
  • The scale of the work
  • Working hours and out-of-hours timing

We don’t list prices on the website, because each job is priced on what it involves. For a fixed quote, call 0345 646 2711 or email us, and we will talk you through it.

Asking for a quote

There’s no need for technical detail. It helps if you can send:

  • The times we could work without disrupting the site
  • Any previous report or certificate
  • The postcode and the type of business
  • Any access panels or hatches you can see

We do not publish a price list, because no two systems are the same. We look at your system first, from pictures or on a visit, then send a fixed quote. To start, ring 0345 646 2711 or drop us a line.
