AHU cleaning for kitchens and businesses in Lidsing
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. The work covers internal panels, dampers and louvres and filter sections, and the jobs we see most are units needing a clean before a new tenant or handover and odours coming through the supply air.
Rural buildings with mechanical ventilation, such as care homes and country hotels, often keep their units in roof spaces or outbuildings, which makes them easy to overlook.
Think of the report as the system’s health record: dated, with photos, and showing what was done. For TR19® Grease cleans, the certificate comes through the BESCA Vent Hygiene Elite portal, ready for your insurer.

FAQs for Lidsing
Do you do school ventilation cleaning in Lidsing in the summer holidays?
Yes. The holidays are the usual time for school work. Around Lidsing, the Food Standards Agency lists about 6 schools and colleges with registered kitchens within a mile and a half or so. Just ring 0345 646 2711, or send details by email with your term dates and we will plan around them.
Will you come out to Lidsing?
Yes, we work in villages as well as towns, and Lidsing is covered. Let us know about access, parking and anything unusual about getting there when you book.
How much does AHU cleaning cost in Lidsing?
Every site is different, so each gets its own fixed quote. To get one, give us a ring on 0345 646 2711, or email photos and tell us about the site and its opening hours.
What happens if you cannot reach some of it?
Anything we cannot reach goes on the report, with photos where possible, and we explain what access is needed, such as extra access panels in ductwork.
Do you survey before quoting?
Yes, every time. Diagnosis comes before treatment: the survey shows what needs doing and what access we need, and the quote is based on that.
How often should an air handling unit be cleaned?
There’s no single answer; it comes down to the building and the unit. Inspection tells you when cleaning is needed, and we’ll suggest an interval after the first clean.
Can you quote from photos?
Normally, yes. Send wide shots, close-ups of any access panels and anything that worries you, and a fixed quote usually follows within one working day. If pictures are not enough, we’ll survey first.
How do you keep the site clean during the work?
We start with protection: sheeting over floors, worktops and anything close to the work. We tidy up and take our waste away before we leave.
Looking after it afterwards
After the visit, a few habits help the work last:
- Don’t ignore odours coming through the grilles
- Report stiff or damaged access doors
- File each AHU report in the maintenance log
- Make sure condensate is draining away
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.
Have the unit inspected regularly, in line with the risk-based approach of TR19® Air, rather than waiting for a problem.
What we do, step by step
There are three stages on the day: set-up, the treatment itself and the sign-off. Getting ready means protecting surfaces and switching off what needs to be off, while signing off means the written report and photos. Most of the time goes on the work itself, which takes a single shift for a typical unit, longer for large or heavily soiled ones. Somewhere like Lidsing, lanes, gates and parking are worth mentioning in advance.
- 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.
- Standing water and slime come out of the tray and the drain is checked.
- A TR19® certificate and photo report follow the clean.
How to prepare
- Move anything stored near the system
- Arrange a key holder or contact on site
- Let us know about parking and loading
How to get a quote
Every quote begins with a look at the system, either from pictures and details you send or from a site visit. Then we send a fixed price, before we start.
Advice
Common problems we fix in Lidsing
It matters for two reasons: air quality, since the unit feeds occupied rooms, and performance, since dirt makes it strain. For the people using the building every day, that’s the air they breathe for hours on end.
It’s time to book a visit if you see:
- Intake sections clogged with outdoor debris
- Plant that has been serviced but not cleaned
- Filters that are clogged or overdue
- Condensate trays that will not empty
School buildings such as Swingate Primary School are typically done in the holidays, so classrooms aren’t disturbed.
Questions to ask before you book
- Which accreditations they hold, and whether you can check them
- Whether the quote is based on a survey or pictures
- What insurance they carry
- When they can work, and whether that’s outside your opening hours
How we price AHU cleaning
The price is fixed before any work begins. It’s based on:
- Parking and loading at the site
- The scale of the work
- What state the system is in
- When the work can happen, such as evenings, overnight or weekends
Whatever the type of site, the quote works the same way: how much there is, how we reach it, what state it’s in and when we can work. Ask for a fixed quote and we will explain each part.
What to send for a quote
When you call or email, it’s useful to have:
- Where the plant sits or the system leaves the building, such as a roof or outside wall
- A few general shots of the system
- Problems your staff have spotted
- The times we could work without disrupting the site
We do not publish a price list, because every site is different. Instead, we look at your site first, from photos or a survey, then send a fixed quote. To start, phone us on 0345 646 2711 or drop us a line.
Lidsing buildings and their air
There are about 6 schools, colleges and universities and about 9 caring premises (care homes, nurseries and hospitals) on the FSA’s food hygiene register within 1.5 miles or so of the middle of Lidsing. Many buildings of this kind have supply and extract ductwork that gathers dust and needs inspecting. Lidsing’s nearest hospital, KIMS hospital, is about 3 miles south. Clean air matters most where people are unwell, and that is as true in a care home as in a hospital. Lidsing, about 31 miles from central London, is within our usual area. A survey and a fixed quote come first, then the visit at a time that suits you.
KIMS hospital, about 3 miles south, is the nearest hospital to Lidsing, and healthcare sites of every size need their supply air kept clean.
Lidsing is about 2 miles south-east of Chatham, in Medway. Whatever kind of site you run in Lidsing, we can take on AHU cleaning. Visits can be booked for evenings, overnight or weekends so the site keeps running. Across Medway, we cover 68 places, and Lidsing is one of them.
Our technicians cover all of ME7 for AHU cleaning and the roads nearby. We also cover Dunn Street (1 mile south-east), Bredhurst (1 mile east), Lordswood (1 mile north-west), Kemsley Street (1 mile east) and Scragged Oak (1 mile south-east).

Local landmarks in Lidsing
We work in commercial kitchens and buildings around South Wood, The Harrow pub and Greenacre Academy and the streets around them. For rail, the closest station is Rainham (Kent) station, roughly 3.3 miles north-east. Other landmarks nearby include Allington Castle (3.3 miles south-west) and Medway megaliths (2.8 miles west). Open spaces near Lidsing include Boxley Hills and Burham Down.
What happens if it’s left?
Standing water in a drain tray doesn’t clear itself. 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. If the system at a site near Lidsing fails, there may be nowhere nearby to move to.
No two sites are the same, so each one gets its own fixed quote. Size, access, the condition of the system and when we can work all play a part.

Other services in Lidsing
Different parts, different methods
Heating and cooling coils
Because cooling coils run wet, the dirt on them tends to cling. The coil and its drain tray are cleaned as one job.
Filters
Dirty filters cut airflow and let dirt slip past their frames. The filter section is cleaned so new or cleaned filters sit properly.
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.
Your own staff can handle the daily basics: wiping canopies, washing grease filters and recording it in a log. Inside the ducts, risers and fan is specialist work, and that’s where we come in.
