AHU cleaning for kitchens and businesses in Littleton
Where a building in Littleton has had little more than filter changes, the coils, fan and casing can be carrying far more dirt than anyone has seen. A full clean deals with all of it. The work covers filter sections, drain trays and heating and cooling coils, and common reasons people get in touch are odours coming through the supply air and dust-coated heating and cooling coils.
For a building in or near Littleton, access is agreed in advance and the visit is planned around the journey, and the ventilation is inspected, cleaned and recorded the same as anywhere.
For insurers and inspectors, the record counts. That is why every job is written up in a report with pictures, and grease extract cleans come with a TR19® certificate issued through the BESCA Vent Hygiene Elite portal.

Multi-site and managed buildings
We also work for facilities teams across offices, schools and healthcare in Littleton and across Surrey. Work can be phased by floor, building or site around the people who use them.
Landlords, managing agents and facilities managers book us, not only the businesses that use the systems. Where a system serves more than one tenant, such as a shared riser, it helps to agree who arranges the work, and we are happy to quote for all of it.
Aftercare tips
Here’s the after-treatment advice, short and simple:
- Don’t ignore odours coming through the grilles
- Stick to the filter change plan
- Check the drain tray is emptying during routine visits
- Watch for drips or damp patches near the plant
The ducts served by the unit may need attention too. A clean unit feeding dirty ducts only solves half the problem, and we can survey both.
Keep the unit’s doors and panels in working order. Sections that are awkward to open are the ones that get skipped.
When something else is needed
We’ll always give you a straight diagnosis, so here’s what this work can’t put right:
- Breakdowns that need a mechanical engineer
- A system that is undersized for the building
- Leaking heating or cooling coils
If in doubt, give us a ring on 0345 646 2711 or email us and we’ll say what we think before you book.
What the work covers
- Drain trays
- Dampers and louvres
- Internal panels
- Filter sections
- Heating and cooling coils
- Supply and extract fans
Fixed quotes for AHU cleaning in Littleton
We do not publish a price list, because no two systems are the same. What we look at:
- Any permits to work or inductions
- The size of the system
- One-off work versus a regular cycle
- Travel, parking and unloading
When the work has to happen, how we reach it and how big the site is can all change the price. We take each of them into account and give you a fixed price before we start.
What to send for a quote
We can often survey from photos. Try to include:
- Your opening hours and when the area is out of use
- Any symptoms, from odd noises to smells or leaks
- A few general shots of the system
- Where the site is and what kind of site it is
Getting a quote doesn’t take long. Send a few details and photos, and we typically reply with a fixed quote within one working day. If we need to see the system first, we book a survey around your hours.
How the job changes from site to site
Fans and fan sections
Build-up on fan blades can upset the balance and add 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.

Ventilation in Littleton buildings
Food Standards Agency data includes about 9 schools, colleges and universities and about 6 hospitals, care homes and childcare premises within 1.5 miles or so of the middle of Littleton. Busy, occupied buildings like these are where clean supply air matters most. Littleton, about 29 miles from central London, is within our usual area. The visit is fixed around your opening hours, not ours. For Littleton, the closest hospital is Farnham Road Hospital, roughly 1.5 miles north-east. Clean air matters most where people are unwell, and that’s as true in a care home as in a hospital.
Hospitals such as Farnham Road Hospital (about 1.5 miles north-east) show how much a building can rely on clean ventilation, and smaller healthcare sites near Littleton are no different. If you manage a school such as Loseley Fields Primary School, ventilation cleaning is best booked for the holidays.
Littleton is about 1 mile north of Farncombe, in Surrey. We provide AHU cleaning for commercial premises of every kind in Littleton and the rest of Surrey. Littleton is one of 395 towns, villages and districts in Surrey we cover for AHU cleaning.
Work in GU3 is surveyed, quoted and booked the same way as anywhere else. Neighbouring places we cover for AHU cleaning include Binscombe (1 mile south-west), Onslow Village (1 mile north), Compton (1 mile west), Hurtmore (2 miles south-west) and Wood Street Village (3 miles north-west). Larger places within reach include Woking (7 miles north), Camberley (10 miles north-west), Farnham (8 miles west), Egham (15 miles north), Walton-on-Thames (14 miles north-east) and Dorking (12 miles east).
Around Littleton
We work in commercial kitchens and buildings around Farncombe Wood, The Withies Inn and Broadwater School and the streets around them. For rail, the closest station is Farncombe station, roughly 1.3 miles south of the centre. Well-known places in the area include Surrey Police Museum (0.7 miles north-east) and Farnham Road Hospital (1.5 miles north-east). For a walk, there’s Lower Lake and St Catherine's Hill.
How it 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. The visit takes a single shift for a typical unit, longer for large or heavily soiled ones. Rural roads and tight entrances are worth telling us about before a visit to Littleton.
- We agree a shutdown window that suits the building.
- We take before photos of each section of the unit.
- We work through the unit from the intake to the outlet.
- The fan and drain tray are cleaned and the drain checked.
- After pictures are taken and the certificate issued.
Getting ready for the visit
- Clear the space around the work
- Let us know about permits to work or site inductions
- Make sure equipment near the work can be switched off and left to cool

Advice
Questions from Littleton
Can a school’s ventilation in Littleton be done out of term time?
Yes, holiday work suits schools best. There are about 9 schools, colleges and universities on the FSA’s food hygiene register within about 1.5 miles of Littleton. Just call us on 0345 646 2711 or send us an email with your term dates and we will plan around them.
Do you cover smaller places like Littleton?
Yes, Littleton is part of our area, however small the site. Photos of the system and directions to the site help us plan the visit.
Which accreditations do you hold?
We hold CHAS, SafeContractor and ISO 9001, alongside BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease. Vent Hygiene Elite is run by BESCA and independently audited.
How long will the unit be out of action?
Cleaning takes from a few hours for a compact unit to a day or more for a large one. Bigger units can be phased, and you can give us a ring on 0345 646 2711 or drop us a line to plan it.
Will we get paperwork for the AHU clean?
Yes, both a certificate and a report with photos. It includes a recommended date for the next check.
Do you offer emergency callouts?
Yes. For anything urgent, such as a fan failure or damage after a fire, ring the 24/7 line, and we’ll advise on what to do next.
How do you keep the site clean during the work?
By covering it before any work starts. We keep the work contained and leave the area clean.
Can you clean the AHU out of hours?
Yes. Evening, overnight and weekend work is all possible, so offices, schools and shops can carry on.
Why deal with it now?
A slimy drain tray only gets worse. Left alone, it can overflow, leak into the plant area or ceiling below and spread smells through the system. Dealing with it early keeps the clean straightforward. A fault that closes a site in a village like Littleton affects everyone who depends on it.
What you pay depends on how big the system is, what state it’s in and access to every part of it. You get a fixed price before we start, so there are no surprises.
