Bryant's Bottom questions
Can you clean school ventilation in Bryant's Bottom during the holidays?
Yes. Half-terms and the summer break are the natural time for school work. Around Bryant's Bottom, the Food Standards Agency lists about 4 schools and colleges with registered kitchens within a mile and a half or so. You can phone us on 0345 646 2711 or drop us a line with the dates the site is empty.
Can you get to a site in Bryant's Bottom?
Yes. Bryant's Bottom is within the area we cover across London and the South East. A survey first, from pictures or a visit, means we arrive with the right kit.
What happens to the waste?
Anything we remove is contained as we work and taken away with us, including grease, debris and dirty water. We do not leave it behind.
Do you survey before quoting?
Yes, always. Diagnosis comes before treatment: the survey shows what needs doing and what access we need and the fixed quote is built on it.
How do you protect the area?
Floors and surfaces near the work are sheeted before any work starts, and waste is contained as we go. At the end, the area is cleaned down.
What do you clean inside the unit?
Every section that collects dirt: filters, coils, tray, fan and panels. We confirm the scope after looking at the unit.
Do you offer maintenance contracts?
Yes, of course. Tell us what you have and how it’s used, and we will suggest a schedule and quote for it.
Will the ventilation be off while you clean?
Yes, while the clean is under way. Out-of-hours work is available so the building isn’t left without ventilation when it’s busy.
AHU cleaning for kitchens and businesses in Bryant's Bottom
Heating and cooling coils trap dust that gets past the filters. Dirt on the fins holds back air and makes the unit work harder to do the same job. We clean coils with methods suited to their condition, taking care not to damage the fins. The work covers heating and cooling coils, supply and extract fans and filter sections, and the jobs we see most are dust-coated heating and cooling coils and plant that needs cleaning after a refit.
In a village or hamlet like Bryant's Bottom, few buildings have mechanical ventilation, but those that do need it inspected and cleaned like any other.
We are CHAS and SafeContractor accredited, we hold ISO 9001 and we are fully insured. On top of that, we are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, trading since 2009.

What your team can do, and what needs us
Staff cleaning doesn’t replace a specialist visit; it supports it. Clean filters and tidy surfaces slow the build-up, but the parts you cannot see still need a specialist at the right interval.
Staff cleaning and specialist work are not the same thing. 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.

What a clean will not put right
We’d rather tell you now than book work that won’t help, so these are the things it won’t cover:
- Ductwork downstream of the unit, which is a separate clean
- Faulty motors, drives or bearings
- Leaking heating or cooling coils
If you are not sure, just call us on 0345 646 2711 or send us an email and we’ll give you a straight answer.

When the unit is clean, less dirt reaches the ducts, so the ducts and grilles stay cleaner between cleans. That makes the next inspection of a building in Bryant's Bottom simpler. A planned visit to Bryant's Bottom is easier to arrange than an emergency callout.

Landlords, agents and facilities managers
From a single site to a large estate, the standard is the same: diagnosis, a fixed price, work booked around your hours and a written report with pictures.
Running several sites is easier with one contractor. We cover South East England and London, so visits at different addresses can be planned together and kept to a regular schedule.
How the visit works
There are three stages on the day: getting the area ready, doing the work and signing it off. Set-up means sheeting and making equipment safe, while signing off means the written report and pictures. The middle part takes longest, which takes half a day to a full day per unit, with large plant planned over several shifts. Rural roads and tight entrances are worth telling us about before a visit to Bryant's Bottom.
- 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 are dealt with as agreed, and the coils, fan and casing cleaned.
- Drain trays are cleared and cleaned and the outlet checked.
- You get a TR19® certificate and a photo report.
Preparing for the visit
- Tell us the best time to work, such as after service or at a weekend
- Allow time for equipment near the work to be turned off and cool down
- Mention any sign-in, permit or induction we need
