- A canopy running with filters missing
- A canopy that drips grease
- Smoke and heat lingering under the hood
What we do, step by step
When we arrive, we check the system against the survey or the photos you sent. If anything is different, we talk it through with the person on site before carrying on. After that, the work takes less than an hour in most kitchens. We plan the journey to Northam and bring what the job is likely to need.
- We record the number, size and type of your filters.
- We set the interval with you.
- On each visit, we remove the greasy filters.
- Clean filters go in and we check they sit snugly.
- We take the greasy set away and confirm the next date.
Getting ready for the visit
- Tell us where we can park and unload
- Allow time for equipment near the work to be turned off and cool down
- Let us know how we reach the system, including roofs, risers and plant rooms
Ask for a quote
Photos are enough for some jobs, while others need a look on site. Big or complicated sites, and systems that are hard to see in pictures, get a survey first. Either way, the quote is fixed before any work is booked.

About our grease filter exchange in Northam
A clean set of filters is a simple, regular dose of prevention. Between full cleans, it keeps the airflow healthy and takes a messy task off your team. The full TR19 clean then gives the system its clean bill of health. The work covers island canopies, baffle filters and wall canopies, and common reasons people get in touch are filters that come out of the sink still dirty and filters left unwashed on busy weeks.
In a smaller place like Northam, the kitchens with extract systems are more likely to be a pub, a café, a takeaway or a school or care home kitchen than a big restaurant. Quieter kitchens still collect grease in the duct, just more slowly, so cleaning is planned around how much it cooks and what the readings show.
The report is your system’s health record: a dated account with pictures of everything we did. For TR19® Grease cleans, the certificate comes through the BESCA Vent Hygiene Elite portal and sits alongside the report.

Why act early in Northam
Dripping canopies and greasy smells often start with the filters. Drips land on surfaces and equipment below, which an EHO may well notice. You choose the date of a planned visit, and a breakdown never asks.
We do not list prices on the website, because each job is priced on what it involves. Call for a fixed quote, and we’ll explain what it covers.

Between visits
How long the results last depends on use and care. We suggest:
- Clean the canopy surfaces regularly
- Clear anything stored on or near the canopy
- Don’t refit a filter that is bent
- Report a dripping canopy early
The canopy looks cleaner and the air moves better from the moment they’re fitted. Always run the extract during cooking so the filters do their job.
If filters are already dripping, they’re overdue. A clean set right away cuts the grease in the canopy, and it’s worth checking the plenum too.
Do you need grease filter exchange in Northam?
Kitchens in Northam, as everywhere, find filter washing slips down the list on busy weeks. It only takes a couple of missed weeks for filters to fill with grease.
Look out for these warning signs:
- Gaps where filters have been removed
- Poor airflow through the filters
- Grease collecting in the filter channels
- Staff short of time to wash filters
If you look after a school kitchen, at a school such as Bitterne Manor Primary School or anywhere near Northam, the holidays are the usual time for a TR19® clean.

What affects the cost of grease filter exchange
You will get a fixed price before work begins. It’s based on:
- One-off work versus a regular cycle
- The condition we find in the survey
- When the work can happen, such as evenings, overnight or weekends
- Whether several sites go on one quote
Several systems or sites on one quote often makes better use of the time. Mention every system or site you need covered, and you’ll get one fixed quote.
Helping us quote
Photos let us diagnose from a distance. Try to include:
- Where the plant sits or the system leaves the building, such as a roof or outside wall
- Problems your staff have spotted
- Close-ups of filters, grilles, hatches or access panels
- When the site is open and when it’s quiet
Getting a quote does not take long. Call or email with a few details and you will usually have a fixed price within one working day. Where a survey is needed, we arrange a time that suits the site.
Questions from Northam
Will you come out to Northam?
Yes, Northam is part of our area, however small the site. Photos of the system and directions to the site help us plan the visit.
Which fire service covers Northam?
Fire safety enforcement in Northam is handled by Hampshire and Isle of Wight Fire and Rescue Service. TR19® is not law, but it’s the benchmark many fire officers and insurers look to when they ask how often the extract is cleaned.
Which records should we keep?
Anything that proves the system is maintained: our reports and pictures, any certificates and your in-house logs. A single log for each site works best.
How do you protect the area?
By covering it before any work starts. The work is kept contained and leave the area clean.
What happens to the dirty filters?
They leave with us. That’s how an exchange works: you always have a clean set fitted, with no washing for your team.
What types of filter do you exchange?
We work with both baffle and mesh filters. The first step is recording what you have and set up the service around them.
Do you offer maintenance contracts?
Yes. We run scheduled maintenance contracts, with visits at the interval your system needs. Each report recommends when the next visit should be.
Which sectors do you work in?
Any site with a kitchen or a ventilation system to look after, from a small pub to a hospital. Hotels, schools, care homes, offices, shops and leisure sites are all part of our work.
Multi-site and managed buildings
Whether it’s one building or many, the standard is the same: diagnosis, a fixed price, work booked around your hours and a written report with pictures.
If you look after several sites, we can plan visits across the whole estate and price them together. Each site gets its own report and pictures, so each one has its own record.
Grease filter exchange around Northam
At about 2 miles from the coast, Northam is close enough for sea air to matter. Corrosion on the fan housing and cowl is worth a look at every clean, alongside the grease. There are about 310 restaurants, cafés and canteens and about 109 takeaways across Northam and its immediate surroundings (about a mile and a half), according to the Food Standards Agency’s register. Clogged filters slow the airflow, and busy kitchens like these clog them fast. Fire safety in Northam falls to Hampshire and Isle of Wight Fire and Rescue Service. Grease in a kitchen extract is a recognised fire risk, and the fire authority enforces the law on managing it in most commercial premises.
Healthcare kitchens cannot easily close, so their extracts are cleaned overnight or between meal services; the nearest hospital to Northam is Royal South Hants Hospital, about 0.8 miles west. Volunteers running a hall kitchen near Church of St Augustine, or anywhere in Northam, may not know when the extract was last cleaned, and a grease test settles it.

What a clean will not put right
In fairness, some problems need a different fix:
- Greasy ducts and risers that a filter change won’t reach
- A heavily greased plenum or canopy, which needs cleaning to TR19
- Cooking smells reaching neighbours, which need odour control
