What AHU cleaning looks like in Kingswood
Food Standards Agency records list about 3 schools, colleges and universities and about 9 hospitals, care homes and childcare premises registered as food businesses in and around Kingswood, up to about a mile and a half out. Where buildings like these have air handling units, filters, coils and drain trays need regular attention. At about 15 miles from central London, Kingswood sits well inside the area we cover. Evening, overnight and weekend visits are all possible. Kingswood’s nearest hospital, Headley Court, is about 2.9 miles west. Hospitals show how much a building can rely on its ventilation, and smaller healthcare sites rely on theirs too.
Healthcare buildings such as Headley Court, about 2.9 miles west, depend on their ventilation; if you manage a surgery, clinic or care home near Kingswood, yours matters too. Wherever a school like Tadworth Primary School has ducted ventilation, a half-term visit keeps the work out of lesson time. If you manage offices or shops near Kingswood station, their ventilation can be inspected and cleaned out of hours.

What affects the cost of AHU cleaning
Your quote is based on your site. We consider:
- The scale of the work
- Whether several sites go on one quote
- Site requirements such as sign-in and permits
- Whether we need access equipment or extra panels
No two sites are the same, so we price each one individually. Size, access, the condition of the system and when we can work all make a difference.
Helping us quote
A few details help us quote accurately. With your enquiry, please include:
- Where the site is and what kind of site it is
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
- The paperwork from the last visit, if you have it
- Any access panels or hatches you can see

How the visit works
There’s very little for your team to do on the day. A contact on site lets us in at the agreed time and points us to the system, and we take it from there. Before we leave, the area is tidied and the paperwork follows. For a place like Kingswood, we load the van from the survey notes so the work can be done in one visit where possible.
- We start with a survey of the unit and a fixed quote for the work.
- We arrange the shutdown with your staff and sheet the area.
- Filters, coils, fan section and casing are cleaned in turn.
- We clean out the drain tray and make sure it drains.
- You get a TR19® certificate and a photo report.
How to prepare
- Let us know about parking and loading
- Let us know about permits to work or site inductions
- Find the previous report, if there is one

Other services in Kingswood
What your team can do, and what needs us
Day-to-day cleaning is something your team can do: wiping canopies, washing grease filters and recording it in a log. Inside the ducts, risers and fan is specialist work, which is where we come in.
For ventilation and air handling systems, in-house care is mostly about checks: keeping grilles clear, noting unusual noise or smells and logging filter changes. The inside of ducts and units needs a specialist.
Managing agents and facilities teams in Kingswood
Under the Regulatory Reform (Fire Safety) Order 2005, the responsible person must assess and reduce fire risk, and that can be the employer, the owner, a landlord, a facilities manager or a managing agent. With shared responsibility, good records help everyone.
We also work for facilities teams across offices, schools and healthcare in Kingswood and across Surrey. Work can be phased by floor, building or site to keep disruption down.
FAQs for Kingswood
Can ventilation in schools around Kingswood be cleaned out of term?
Yes, out-of-term visits are normal for schools. Around Kingswood, the Food Standards Agency lists about 3 schools and colleges with registered kitchens within a mile and a half or so. Booking early in the term gives the best choice of holiday dates.
Do you cover smaller places like Kingswood?
Yes, smaller places are covered as well as towns. A survey first, from pictures or a visit, means we arrive with the right kit.
What happens if you can’t reach some of it?
We record them on the report, with a note of where it is, and we tell you what would make it reachable, such as extra access panels in ductwork.
What’s included in an AHU clean?
Everything inside the unit that air passes over, from intake to discharge, including coils, fan and drain trays. The photo report shows each section before and after.
Are you insured?
Yes. Duct Doctor is fully insured, and we can share the details when you need them.
Does the AHU have to be shut down for cleaning?
Yes. The fan must be stopped and the unit isolated, and we time the work to suit the site.
Do you give a certificate after the clean?
Yes, a TR19® certificate and a photo report. It includes a recommended date for the next check.
Do you clean the ductwork as well?
Yes, supply and extract ducts, grilles and diffusers. The survey shows whether the ducts need cleaning now.
Between visits
To keep the system working properly between visits:
- Book the next check in line with the report
- Report water on the plant room floor
- Make sure condensate is draining away
- Store the TR19 paperwork where auditors can find it
The report suggests a date for the next inspection or clean, based on what we found. TR19® Air is risk-based, so the interval depends on the unit and how the building is used.
Keep the area around the intake clear. Anything around the intake is likely to be drawn in.
How the job changes from site to site
Heating and cooling coils
Coil fins are close together and catch the dust the filters miss. We clean them with care so the fins aren’t damaged.
Internal casing and panels
Access doors and panels are opened in turn and closed properly afterwards, and check every one is shut.
What AHU cleaning can’t fix
Some problems need a different service or another trade:
- Coils that are corroded or leaking and need replacing
- Dirty ducts beyond the unit itself
- Building management system faults
If in doubt, give us a ring on 0345 646 2711, or send details by email and we will say what we think.
