How we handle AHU cleaning in Seething Wells
Units vary a lot in size, age and layout, whether it’s a compact unit in a ceiling void or a big unit on the roof. We look at the unit first, from photos or a site visit, and give you a fixed quote before any cleaning starts. The work covers filter sections, internal panels and supply and extract fans, and the jobs we see most are intake sections clogged with outdoor debris and condensate trays that won’t empty.
London offices and flats often have ductwork added through successive refits, leaving sections that are hard to reach and seldom cleaned. In Seething Wells, as elsewhere, cleaning starts with an inspection of what’s there.
Nothing is signed off by word of mouth: a dated report with photos of the work, and for TR19® Grease cleans, a certificate issued through the BESCA VHE portal. It shows what was done and what, if anything, couldn’t be reached.

For landlords and multi-site operators
Multi-site operators often want one contractor and one number. We work across London and the South East, so a run of sites can go into one programme and kept on a regular cycle.
Managing agents often deal with us directly. Tell us the site, the work and the access arrangements and we’ll come back with a fixed quote.
Fixed quotes for AHU cleaning in Seething Wells
Some jobs are bigger than they look, and some smaller. What affects the quote:
- A single visit or a regular plan
- Any permits to work or inductions
- Access, including roofs, risers and ceiling voids
- How many systems or sites are involved
You will not find a price list here, because the cost depends on the site in front of us. For a fixed quote, ring 0345 646 2711, or send details by email, and we will talk you through it.
What we need to know
When you call or email, these details help:
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
- Photos showing the whole system and its surroundings
- The times we could work without disrupting the site
- Where the plant sits or the system leaves the building, such as a roof or outside wall
For a fixed quote, phone us on 0345 646 2711 or drop us a line and tell us the type of site, your opening hours and roughly what the system looks like. Photos and the last report, if you have one, make the quote quicker. You’ll typically have a quote within one working day.
How the job changes from site to site
Internal casing and panels
Damaged internal linings or loose panels can shed material into the air. We note any we find in the report.
Fans and fan sections
Dust on a fan impeller adds weight and wear. A clean fan runs more smoothly.
Leave it or put it right?
A clogged coil or dirty fan makes the unit work harder for the same airflow. The result is extra wear and a building that does not feel as comfortable, and a planned clean is far less disruptive than a breakdown. It’s better booked as a planned job in Seething Wells than handled as an emergency.
The cost depends on how big the system is, the condition it’s in and how easy it is to reach. We give you a fixed price before we start, so you know where you stand.
What you get with us
- One number for every site across the South East and London
- Accredited under CHAS and SafeContractor, with ISO 9001
- Trading since 2009
- We diagnose before we treat

Questions from Seething Wells
Can you work in Seething Wells outside opening hours?
Yes, nights and weekends are routine for us. The site is handed back ready to open. When you give us a ring on 0345 646 2711, or send details by email, mention when the site is quiet.
How do you handle parking and loading in Seething Wells?
London parking can be tight, so details of loading bays and permits help. If the building has a loading slot system, we’ll book into it.
Are you fully insured?
Yes. We’re fully insured, and the details are available on request.
How much notice do you need?
That depends on the slot you want and the size of the job. Tell us your preferred dates when you ask for a quote, and if it’s an emergency, call us any time.
Do you work with multi-site operators?
Yes. Our area covers London and the South East, so we can schedule a run of sites as one programme. Each site gets its own report and photos.
Is a quote from pictures possible?
Often, yes. Photos of the system and the access, plus your opening hours and last report, are often enough. Larger or hidden systems need a survey on site first.
Do you survey before quoting?
Yes. For many sites, photos and a few details are enough, while bigger or harder-to-see systems are surveyed on site.
Can you set up regular visits?
Yes. We run scheduled maintenance contracts, set at the interval the system needs. Each report recommends when the next visit should be.

What AHU cleaning looks like in Seething Wells

Classrooms, bedrooms and care spaces are often served by ducted air, and that ductwork collects dust over time. About 1.4 miles south-east of Seething Wells is Tolworth Hospital, the nearest hospital. Clean air matters most where people are unwell, and that’s as true in a care home as in a hospital. Getting kit to a London plant room normally means lifts, stairs and an agreed loading slot.
Healthcare buildings such as Tolworth Hospital, about 1.4 miles south-east, depend on their ventilation; if you manage a surgery, clinic or care home near Seething Wells, yours matters too. For workplaces around Surbiton station with mechanical ventilation, cleaning can be done in the evening or at weekends. Classrooms and halls at schools such as Maple Infants' School are easiest to work in when pupils are away.

Staff cleaning versus specialist work
In-house cleaning and specialist cleaning do different jobs. Wiping filters daily and washing them weekly keeps the visible parts in order, but grease that has passed the filters is out of reach. Reaching it takes a specialist with the right equipment.
Good housekeeping makes our visits easier, not unnecessary. Regular in-house cleaning slows the build-up, but hidden parts of the system still need specialist attention.
Keeping the system healthy
Results last longer with the right care. We suggest:
- Do not ignore odours coming through the grilles
- Clear leaves and litter away from the intake
- Watch for drips or damp patches near the plant
- Report stiff or damaged access doors
The report shows each section of the unit before and after, and note any part we couldn’t get to. It also notes faults we spotted, such as damaged panels or a blocked drain.
Don’t let leaves, litter or stored materials build up near the fresh air intake. Anything around the intake is likely to be drawn in.
How the visit works
At the end of the visit, someone from your team can look over the work with us. Anything we couldn’t reach or that needs attention is pointed out there and then, and the same goes into the written report. All told, the work takes a single shift for a typical unit, longer for large or heavily soiled ones. A name and number for whoever controls access to the building in Seething Wells saves time on the night.
- We start with a survey of the unit and a fixed quote for the work.
- With your site team, the unit is switched off and isolated, then the area around it protected.
- Filters, coils, fan section and casing are cleaned in turn.
- We clean out the drain tray and make sure it drains.
- A TR19® certificate and photo report follow the clean.
Getting ready for the visit
- Dig out any earlier paperwork for the system
- Move anything stored near the system
- Allow time for equipment near the work to be turned off and cool down
