About our grease filter exchange in Heathfield
Baffle filters and mesh filters both fill with grease. Once they’re clogged, airflow drops and the extract struggles. Regular exchange keeps the air moving. The work covers mesh filters, baffle filters and school and hospital kitchens, and people most often call us about grease filters clogged with grease and damaged filters letting grease past.
In a smaller place like Heathfield, many kitchens sit in older buildings or later extensions, with the duct running through a roof space or up an outside wall. Flat runs collect grease and need proper access to clean.
Duct Doctor has been trading since 2009, as a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we are fully insured.

What your team can do, and what needs us
In-house cleaning and specialist cleaning do different jobs. A daily filter wipe and a weekly filter wash keep grease down at the front of the system, but grease that has passed the filters is out of reach. That part needs specialist access and equipment.
Day-to-day cleaning is something your team can do: wiping down canopy surfaces, cleaning filters and keeping a simple log. Inside the ducts, risers and fan is specialist work, which is where we come in.
Landlords, agents and facilities managers
Running several sites is easier with one contractor. We cover South East England and London, so a run of sites can go into one programme and kept on a regular cycle.
Facilities teams in offices, schools and healthcare sites book us too in Heathfield and across Hampshire. Work can be phased by floor, building or site to keep disruption down.
Common questions in Heathfield
Do you clean school canteen extracts around Heathfield out of term?
Yes. The holidays are the usual time for school work. Around Heathfield, the Food Standards Agency lists about 21 schools and colleges with registered kitchens within a mile and a half or so. You can give us a ring on 0345 646 2711 or use the quote form with the dates the site is empty.
Does the sea air around Heathfield make a difference to grease filter exchange?
It can. Salt air reaches Heathfield, which is within about 3 miles of the coast, and it speeds up rust. Rooftop fans, discharge cowls and fixings are checked for corrosion as well as grease.
How much notice do you need?
For planned work, earlier is better, particularly if your next visit is nearly due. Emergencies are different, because our line is open 24/7.
Is filter exchange enough instead of a full extract clean?
No. Filter exchange works between full cleans, not instead of them. A TR19® clean deals with the whole system, with a certificate and photo report.
Do you survey before quoting?
Yes. We always survey first, either from photos and details you send or on a site visit. A fixed quote follows.
Do you have a 24/7 line?
Yes, 24/7. Our office is open from 8am to 6pm on weekdays, and the emergency line covers the rest.
Do you have insurance?
Yes. Full insurance covers our work, and we have been trading since 2009.
What happens to the waste?
We contain it and take it with us. We collect grease, debris and waste water as we go rather than letting it spread.
How it works
We turn up at the time agreed with you, often in the evening, overnight or at the weekend so the site keeps working. Equipment that has to be off is switched off and allowed to cool before work begins, and the area around the work is covered and protected. The work itself takes less than an hour in most kitchens. Everything the job in Heathfield needs is worked out beforehand, from the survey.
- We look at the canopies and the condition of the filters.
- Any damaged or missing filters are noted.
- We exchange the dirty filters for a clean set.
- The filters are checked for fit before we go.
- We tell you if the plenum or canopy needs a clean.
Before we arrive
- Tell us about site rules, permits or sign-in
- Have your last certificate or report to hand
- Make sure equipment near the work can be switched off and left to cool
How to get a quote
Quoting starts with a diagnosis, either from pictures and details you send or from a site visit. Then we send a fixed price, before any work starts.

Grease, kitchens and Heathfield
Sea air reaches Heathfield, which sits within about 3 miles of the coast. Corrosion on the fan housing and cowl is worth a look at every clean, alongside the grease. There are about 72 restaurants, cafés and canteens and about 21 takeaways and sandwich shops in and around Heathfield, up to about a mile and a half out, according to the Food Standards Agency’s register. Each canopy among them has filters that load with grease and need swapping or cleaning. Heathfield sits within the area of Hampshire and Isle of Wight Fire and Rescue Service. Fire and rescue authorities enforce the Fire Safety Order in most non-domestic premises, and in a kitchen that fire risk includes the grease in the extract.
If you run a church or community hall kitchen, near St Columba or elsewhere in Heathfield, its extract still collects grease from every lunch and event. If you run a café or takeaway near Fareham station, early starts and late finishes leave little time to clean, so overnight extract cleaning suits.
Heathfield is about 1 mile west of Fareham, in Hampshire. Every kind of commercial site in Heathfield, we can take on grease filter exchange. Visits can be booked for evenings, overnight or weekends so trading isn’t interrupted. Across Hampshire, we cover 683 places, and Heathfield is one of them. Portsmouth is in our area too, around 7 miles away.
Work in PO15 and PO14 follows the same survey, fixed quote and written report as everywhere else we cover. Grease filter exchange is available to premises on Oak Road, Peak Lane and The Avenue and nearby roads. Nearby, we also carry out grease filter exchange in Catisfield (1 mile west), Titchfield (1 mile west), Funtley (1 mile north), Titchfield Park (2 miles north-west) and Little Posbrook (2 miles south-west).

Near you in Heathfield
Typical jobs here are in premises near Fishermans Arms and The Henry Cort Community College and the streets around them. For rail, the closest station is Fareham station, roughly 0.9 miles east. A little further out are Fareham Shopping Centre (1.6 miles east) and Carron Row Farm Museum (1 mile north-west). For a walk, there’s Portsdown Hill and Swanwick Lakes.
Why deal with it now?
When filters block, extraction suffers. The kitchen gets hotter and smokier, and the fan works harder to pull air through. A regular exchange keeps the airflow where it should be. When a site near Heathfield shuts unexpectedly, the people who rely on it notice at once.
Every site is different, so each one gets its own fixed quote. The size of the job, how we reach it, its condition and the working hours all make a difference.

- Fully insured
- Photo reports with every job
- A BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease
Keeping the system healthy
Once we’ve finished, these simple steps help:
- Tell us if the menu or opening hours change
- Report a dripping canopy early
- Keep filter exchange and TR19 cleaning on the same plan
- Do not refit a filter that is bent
The next exchange is already in the diary. If the kitchen gets busier, the interval can be shortened to match.
Dripping filters are a clear sign they’re full. A clean set straight away cuts the grease in the canopy, and it’s worth checking the plenum too.
Do you need grease filter exchange in Heathfield?
What a kitchen cooks affects how fast filters clog. Frying, grilling and chargrilling produce far more grease than steaming or baking so no single schedule suits every kitchen.
Clients normally contact us when they notice one of these:
- Blocked baffle filters
- Filters left unwashed on busy weeks
- Grease dripping from the canopy
- Poor airflow through the filters
If you run catering at a healthcare site, such as a hospital like Knowle Hospital about 2.1 miles north, the extract may need cleaning more often than a part-time kitchen.

What affects the quote in Heathfield
Sites vary more than people expect. The main factors:
- Access, including roofs, risers and ceiling voids
- The size of the system
- Site requirements such as sign-in and permits
- Parking and loading at the site
Leaving it longer rarely makes the work cheaper. Build-up, wear and faults tend to get worse, not better, and a neglected system can mean more work. If you’re not sure what’s needed, call us on 0345 646 2711 or drop us a line for straight advice and a fixed quote.
