Managing agents and facilities teams in Oxshott
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 Oxshott and across Surrey. Work can be phased by floor, building or site around the people who use them.
AHU cleaning for kitchens and businesses in Oxshott
A cooling coil drips condensate into a tray that should drain away. If the outlet blocks, standing water and slime build up, right in the path of the air going into the building. Cleaning and clearing it is a key part of the job. We’re often asked to deal with dust built up on fan impellers and odours coming through the supply air, on supply and extract fans, drain trays and internal panels.
Visits to a place like Oxshott are fitted around opening hours. The work is the same as in any town: inspect, clean, record.
Every visit ends with a written report and pictures, so there’s a dated record of the work. Kitchen extract cleaning to TR19® Grease is certificated through the BESCA Vent Hygiene Elite portal.

Common questions in Oxshott
Can you come to Oxshott after we close?
Yes, out-of-hours work is a big part of what we do. It means the site in Oxshott keeps running as normal. Tell us your opening hours when you ask for a quote.
Do you do school ventilation cleaning in Oxshott in the summer holidays?
Yes. The holidays are the usual time for school work. There are about 3 schools, colleges and universities on the FSA’s food hygiene register within about 1.5 miles of Oxshott. Send us your term dates when you ring 0345 646 2711, or send details by email, and we will fit the work in.
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.
Can one contract cover all our sites?
Yes. Send the list of sites and the work at each and we will quote them together.
Can you fix a faulty AHU?
Mechanical repairs to the unit are for your HVAC maintenance contractor. We clean the unit and report anything we see that needs attention.
When should our AHU next be cleaned?
That’s set by inspection, in line with TR19® Air. A hard-working unit, or one serving a hospital or care home, may need cleaning more often.
Will we get paperwork for the AHU clean?
Yes. You get a TR19® certificate plus before and after photos. Keep them in the maintenance log.
Do you offer emergency callouts?
Yes, any time. 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.
Looking after it afterwards
After the visit, a few habits help the work last:
- Plan the next inspection before the last report gets filed away
- Check the drain tray is emptying during routine visits
- Keep inspection doors on the unit in good order
- Flag stale or damp smells in the supply air
The ducts served by the unit may need attention too. Cleaning the unit and ducts together gives the best result, and we can quote for both.
Have the unit inspected regularly, in line with the risk-based approach of TR19® Air, rather than waiting for a problem.
How the visit works
At the end of the visit, someone from your team can look over the work with us. We point out anything that couldn’t be reached or needs a follow-up, and it goes on the report too. The visit takes one overnight shift for many single units, with bigger plant phased. Evenings, weekends or a closed day all work for a site in a place like Oxshott.
- First the unit is surveyed, from photos or a visit, and the scope agreed.
- The unit is shut down with your site team and the area protected.
- Filters, coils, fan section and casing are cleaned in turn.
- Standing water and slime come out of the tray and the drain is checked.
- You get a TR19® certificate and a photo report.
How to prepare
- Mention any sign-in, permit or induction we need
- Allow time for equipment near the work to be turned off and cool down
- Clear loose items from the work area

Ventilation in Oxshott buildings
The FSA’s food hygiene register lists about 3 schools, colleges and universities and about 3 care, childcare and hospital premises with registered kitchens or food service within roughly a mile and a half of the centre of Oxshott. Where buildings like these have air handling units, filters, coils and drain trays need regular attention. At about 16 miles from central London, Oxshott sits well inside the area we cover. Evening, overnight and weekend visits are all possible. For Oxshott, the closest hospital is Epsom Cottage Hospital, roughly 2.5 miles east. Healthcare ventilation is a good example of why supply ducts need inspecting: the air goes straight to patients.
If you manage shops or offices close to Oxshott station, a TR19® Air inspection shows whether the ductwork needs cleaning. Wherever a school like The Royal Kent CofE Primary School has ducted ventilation, a half-term visit keeps the work out of lesson time. Healthcare buildings such as Epsom Cottage Hospital, about 2.5 miles east, depend on their ventilation; if you manage a surgery, clinic or care home near Oxshott, yours matters too.

Landmarks near Oxshott
We work in commercial kitchens and buildings around Therfield School, Danes Hill School and Claygate Common and the streets around them. There’s a railway station in Oxshott itself: Oxshott station. Other landmarks nearby include Elmbridge Museum (2.6 miles north) and The Ashley Centre (3.8 miles east). For a walk, there’s Jubilee Wood and Claremont Lake.
What staff can safely do
Away from the kitchen, the in-house job is mainly checking: clear grilles, a log of filter changes and reporting anything odd. The inside of ducts and units needs a specialist.
Staff cleaning and specialist work aren’t the same thing. Wiping filters daily and washing them weekly keeps the visible parts in order, but they don’t reach the grease that builds up further in. That part needs specialist access and equipment.

What happens if it’s left?
Leave an AHU uncleaned and the dirt doesn’t stay put. It moves on into the ductwork and out into the rooms, so cleaning the ducts without the unit only goes so far. It’s easy to lose track of when the work was last done on a quieter site.
Leaving it longer rarely makes the work cheaper. Build-up, wear and faults tend to get worse, not better, which can make the next visit longer. If you’re not sure what’s needed, call 0345 646 2711 or send us an email and we will give you an honest view and a fixed quote.
