About our grease filter exchange in Fernhurst
Cleaning filters by hand takes staff time and is easy to put off. With a filter exchange, we bring a clean set and take the dirty one away and the canopy is refilled right away. If you have grease building up behind the canopy filters and filters that come out of the sink still dirty, we can help.
Somewhere as small as Fernhurst, commercial kitchens are few: perhaps a pub, a school or care home kitchen, or a hall used for events. Every one of them still needs its extract kept clear of grease.
Duct Doctor has been trading since 2009, and we’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we carry full insurance.

Keeping the system healthy
Here’s the after-treatment advice, in brief:
- Never leave gaps in the filter bank
- Don’t let the full clean slip because filters are changed
- Report damaged filters so they can be replaced
- Make sure we can reach the canopy on exchange day
We tell you if we spot anything in the canopy that needs attention. It can be a sign that a full TR19® clean is due and we can book that in.
If cooking has stepped up, the filter schedule should too. Changing the interval early stops grease building up unseen behind the canopy.

What else we do in Fernhurst
Your questions about grease filter exchange in Fernhurst
Who enforces fire safety at workplaces in Fernhurst?
Surrey Fire and Rescue Service is the fire and rescue service for Fernhurst. If a fire safety officer visits a commercial kitchen, they may ask about the fire risk assessment and how the extract is kept clean.
Can you work in Fernhurst outside opening hours?
Yes, evening, overnight and weekend work is normal for us. The site is handed back ready to open. Let us know the hours you’re closed and we’ll book within them.
Can we skip TR19 cleans if the filters are changed regularly?
No, the two work together. A TR19® clean deals with the whole system, with a certificate and photo report.
Do you cover Fernhurst?
Yes. We cover Fernhurst and the rest of Surrey, within our South East and London area. For a fixed quote, give us a ring on 0345 646 2711, or email photos.
Are you fully insured?
Yes, fully. CHAS and SafeContractor accreditation sit alongside it, for sites that check contractor safety.
Can you come out in an emergency?
Yes, any time. For anything urgent, such as a fan failure or damage after a fire, ring the 24/7 line and we will talk you through the next steps.
Can damaged filters stay in the canopy?
A badly damaged filter should be replaced. We will tell you which ones and why when we find them.
Can you give a price for filter changes?
Pricing depends on the kitchen, so we quote once we know your filters and schedule. We give you a fixed quote before the first visit.
What affects the quote in Fernhurst
The quote reflects the site in front of us. We take into account:
- A single visit or a regular plan
- The condition we find in the survey
- Site rules, permits and inductions
- How big the system is
Working hours, access and the scale of the site can all change the price. Each of those is built into the quote, and the price is fixed before any work starts.
Asking for a quote
The more you tell us, the more accurate the quote. With your enquiry, please include:
- The paperwork from the last visit, if you have it
- A few general shots of the system
- When the site is open and when it’s quiet
- Any symptoms, from odd noises to smells or leaks
Every quote begins with a look at the system, from your pictures and details or, where that is not enough, a survey on site. Then we send a fixed price, before any work starts.
Multi-site and managed buildings
Records are where multi-site compliance often slips. Each visit ends with a dated report and photos, so you can show an insurer or inspector what was done at each site.
We regularly work with managing agents. Send the address, what’s needed and how access works, and we will send a fixed quote.
Different parts, different methods
Busy restaurant and pub kitchens
Kitchens that fry and grill all day load their filters fast. Their exchange schedule is normally the tightest.
School, care home and staff kitchens
Kitchens that cook for set mealtimes still load their filters though normally at a gentler pace.
Fernhurst kitchens: local notes
Food Standards Agency records list about 3 restaurants, cafés and canteens within 1.5 miles or so of the middle of Fernhurst. Swapping filters on a schedule keeps kitchens like these drawing air properly. Food hygiene inspections in Fernhurst are the job of Chichester council’s environmental health team. They look at how clean the premises and equipment are, and the kitchen extract is part of that. Keeping each certificate and photo report on file helps show the extract is looked after. The fire and rescue service for Fernhurst is Surrey 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 catering at a historic house or estate in the area (Cowdray House is about 4.3 miles south), event kitchens in older buildings often have awkward duct runs that need planning. Kitchens that cook twelve hours or more a day, as some healthcare kitchens do, fall into BESA’s three-monthly minimum; Haslemere and District Hospital is the nearest hospital to Fernhurst, about 2.9 miles north.

What happens if it’s left?
Changing filters on schedule costs far less disruption than a blocked extract. It’s one of the simplest parts of looking after the system and few are as easy to forget. In a small place like Fernhurst, a system that fails can take a site out of use.
Combining work into one visit or one programme often makes better use of the time. Tell us about everything you’d like looked at, and you will get one fixed quote.

How it works
There are three stages on the day: getting the area ready, doing the work and signing it off. Getting ready means protecting surfaces and switching off what needs to be off, while signing off means the written report and photos. The middle part takes longest, and that takes a short visit, depending on how many filters the canopies hold. Somewhere as small as Fernhurst, the date and timings are agreed with you well before the day.
- We count and measure the filters in every canopy.
- A change schedule is agreed to match the kitchen’s cooking hours.
- On each visit, the dirty filters come out of the canopy.
- We fit clean filters and check they sit snugly in the housing.
- Anything we notice, such as bent filters or a dirty plenum, is pointed out.
How to prepare
- Dig out any earlier paperwork for the system
- Let us know when the site is closed or quiet
- Plan for cooking equipment or plant to be off before we arrive
Getting a quote
Photos are the quickest way to a quote: wide shots of the system, close-ups of anything that worries you and how we’d get to it. Add the site type and your opening hours, and many jobs can be priced from that alone.
Related advice
Signs you need grease filter exchange in Fernhurst
The type of cooking matters. Frying, grilling and chargrilling produce far more grease than steaming or baking so no single schedule suits every kitchen.
Keep an eye out for any of the following:
- Filters that leave gaps in the canopy
- Staff short of time to wash filters
- Filters so greasy the air can barely pass
- Grease left in baffles after washing
If you run a church or community hall kitchen, near The Parish Church of St Margaret or elsewhere in Fernhurst, its extract still collects grease from every lunch and event.
