Grease filter exchange in Norcott Hill
Filter exchange sits between full TR19® cleans. Clean filters reduce the grease reaching the ducts, but some grease still passes through as vapour. That is why the whole system still needs cleaning to TR19 at the right interval. If you are dealing with filter washing that keeps being missed and grease collecting in the filter channels, we can help, from restaurants and pubs, school and hospital kitchens and wall canopies onwards.
Work in a small place like Norcott Hill starts with a call to agree access and timings, and the clean covers the whole system, as it would anywhere: canopy, filters, duct, fan and discharge, with a certificate and photo report at the end.
The paperwork matters as much as the work. Each visit is written up with pictures, listing what was done, anything we couldn’t reach and when the next visit is due. Keep it with your fire safety records so it’s ready for an insurer, fire officer or EHO.

Signs you need grease filter exchange in Norcott Hill
Hand-washed filters often come back still greasy. Grease lodges deep in baffles and mesh, and a quick rinse leaves it there.
It’s time to book a visit if you see:
- Grease building up behind the canopy filters
- Filters left unwashed on busy weeks
- Filters that come out of the sink still dirty
- Filters that leave gaps in the canopy
Kitchens that cook twelve hours or more a day, as some healthcare kitchens do, fall into BESA’s three-monthly minimum; Hemel Hempstead Hospital is the nearest hospital to Norcott Hill, about 5.9 miles south-east.
What to look for in a quote
- When they can work, and whether that’s outside your opening hours
- Whether a written report and pictures are included
- Whether inaccessible sections are listed on the report
- If they look at the system before pricing
When something else is needed
Before booking, it helps to know what’s not included:
- A heavily greased plenum or canopy, which needs cleaning to TR19
- Greasy ducts and risers that a filter change won’t reach
- Extraction problems caused by the fan rather than the filters
Not sure which it is? You can call 0345 646 2711 or drop us a line and we will tell you honestly.

Multi-site and managed buildings
Under the Regulatory Reform (Fire Safety) Order 2005, the responsible person must assess and reduce fire risk, and that can be the employer, the owner, a landlord, a facilities manager or a managing agent. With shared responsibility, good records help everyone.
When the building owner and the occupier are different, the lease normally sets out who maintains what. We’re happy to deal with either side and send the paperwork to whoever needs it.
How the visit works
We work around your opening hours, not the other way round. We book the visit for a time the area is closed, whether that is an evening, overnight or a weekend. Once we are in, the area is sheeted and anything that has to be off is turned off and cooled, and the job takes less than an hour in most kitchens. If you can send pictures, we can arrive in Norcott Hill knowing what to expect.
- We record the number, size and type of your filters.
- An exchange schedule is agreed to suit your cooking.
- On each visit, we remove the greasy filters.
- Clean filters go in and we check they sit snugly.
- The dirty filters leave with us and the next visit is booked.
Before we arrive
- Plan for cooking equipment or plant to be off before we arrive
- Have your last certificate or report to hand
- Clear the space around the work

How the job changes from site to site
Canopy filter housings
Every exchange includes a check of how the filters sit, because gaps let grease through.
School, care home and staff kitchens
Even kitchens with fixed meal times build up grease though normally at a gentler pace.
Why deal with it now?
Clogged filters choke the extract. The kitchen gets hotter and smokier while the fan strains. A regular exchange keeps the airflow where it should be. A planned visit to Norcott Hill is easier to arrange than an emergency callout.
You won’t find a price list here, because each job is priced on what it involves. For a fixed quote, call 0345 646 2711 or drop us a line, and we’ll explain what it covers.

Common questions in Norcott Hill
Can school kitchens in Norcott Hill be cleaned in the holidays?
Yes, holiday work suits schools best. With about 3 schools and colleges on the FSA’s register within roughly a mile and a half of Norcott Hill, it pays to plan holiday dates ahead. You can give us a ring on 0345 646 2711 or send us an email with the dates the site is empty.
Who carries out food hygiene inspections in Norcott Hill?
Food hygiene inspections in Norcott Hill are carried out by Dacorum council. How often a business is inspected depends on the risk rating the council gives it, so it’s worth staying ready all year.
Does the report say when we need you again?
Yes. We put a recommended next date on the report. For kitchen extracts, BESA’s minimum intervals run from every 3 months for heavy use to every 12 months for light use, while fire dampers are tested at least annually.
Do you survey before quoting?
Yes, always. Diagnosis comes before treatment: the survey shows what needs doing and what access we need, and the quote is based on that.
What types of filter do you exchange?
Baffle filters and mesh filters. Tell us what you have when you call 0345 646 2711 or email us, or we will check on the first visit.
Will we have to stop cooking for a filter change?
A filter change is quick and can be timed around service. The canopy shouldn’t be used without filters, so we swap them in one go.
Do you have insurance?
Yes. We are fully insured, and the details are available on request.
Do I get a report after the visit?
Yes, always. It’s a dated, written report with photos, and TR19® Grease cleans come with a certificate through the BESCA VHE portal. Keep it in your maintenance log.
How we price grease filter exchange
You will get a fixed price before work begins. It takes into account:
- Access, including roofs, risers and ceiling voids
- Parking and loading at the site
- What state the system is in
- When the work can happen, such as evenings, overnight or weekends
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.
Helping us quote
The more you tell us, the more accurate the quote. With your enquiry, please include:
- Any access panels or hatches you can see
- Your opening hours and when the area is out of use
- How we’d reach plant on a roof or in a plant room
- Where the site is and what kind of site it is
Quoting starts with a diagnosis, from your photos and details or, where that isn’t enough, a survey on site. Then we send a fixed price so you know the cost before any work starts.
