About our extract fan cleaning in Porter's End
In Porter's End, as everywhere we work, the fan follows a set routine: isolated first, then opened, scraped and degreased. The result is photographed for your records. The work covers axial fans, centrifugal fans and discharge points, and people most often call us about rough running from the extract fan and a fan that no longer moves enough air.
For a kitchen in or near Porter's End, the visit is planned around opening hours and the journey, and the clean covers the whole system, as it would anywhere: canopy to discharge, then a TR19® certificate and a photo report.
Each visit ends with a written report and pictures, so there’s a dated record of the work. Where the work is a TR19® Grease clean, the certificate is issued through the BESCA Vent Hygiene Elite portal.

Kitchen extracts in Porter's End
Food Standards Agency records include about 3 pubs and bars across Porter's End and its immediate surroundings (about a mile and a half). Breakfasts, bar meals and functions all put grease into the extract wherever they’re cooked. Kitchens in Porter's End get their food hygiene inspections from North Hertfordshire council. A greasy canopy or dripping filters are the sort of thing an inspection can pick up. Our report lists what was cleaned and when, which is useful to have ready. Porter's End is covered by Hertfordshire Fire and Rescue Service. In most workplaces, including commercial kitchens, it’s the fire and rescue authority that enforces the Fire Safety Order.
If you run catering at a healthcare site, such as a hospital like St Albans City Hospital about 5.7 miles south, the extract may need cleaning more often than a part-time kitchen. If your kitchen is in a listed or historic building, like the houses around Porter's End (Shaw's Corner is about 2 miles east), fitting access panels needs care.
Porter's End is about 2 miles north-east of Harpenden, in Hertfordshire.

Leave it or put it right?
Cleaning the fan in Porter's End now is a short job: the work takes a couple of hours per fan, depending on its size and the build-up. Waiting adds vibration, wear and a harder clean. A fault that closes a site in a village like Porter's End affects everyone who depends on it.
Whatever the type of site, the quote works the same way: the size of the job, access, condition and working hours. Ask for a fixed quote and we’ll explain each part.
Why us?
- Survey first, then a fixed quote
- One number for every site across the South East and London

What affects the quote in Porter's End
We quote each job individually. This is what makes a difference:
- How easy every part is to reach
- The scale of the work
- When the work can happen, such as evenings, overnight or weekends
- The number of sites or systems
Working hours, access and the scale of the site all affect the cost. Each of those is built into the quote and give you a fixed price before any work starts.
What to send for a quote
We can often survey from pictures. The most useful are:
- When the site is open and when it’s quiet
- A few general shots of the system
- Close-ups of filters, grilles, hatches or access panels
- The paperwork from the last visit, if you have it
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.
What a clean won’t put right
Extract fan cleaning cannot fix everything, and we will tell you before work begins. It will not put right:
- Grease in the canopy and ductwork
- Electrical faults in the fan’s supply or controls (an electrician’s job)
- An impeller that is bent or split
If in doubt, call us on 0345 646 2711, or send details by email and we will say what we think.
What we work on in Porter's End
- Roof-mounted fans
- Discharge points
- Fan housings
- In-line fans
- Centrifugal fans
- Axial fans
How the job changes from site to site
Impellers and blades
Coated blades move less air. Scraping and degreasing them restores their shape, so the fan can run as intended.
Inline duct fans
Hidden in a ceiling void, an inline fan is easily missed. The survey makes sure it’s part of the clean.
How it works
A visit follows the same order every time: protect the area, isolate whatever needs isolating, do the work, tidy up and leave you the report. On site, the work takes a few hours where there are several fans or heavy deposits. In a small place like Porter's End, the journey is planned ahead and the visit arranged around the site’s hours.
- First we locate the fan and agree how it’s safely isolated.
- Power to the fan is isolated before anyone touches it.
- Grease is scraped from the impeller blades and the inside of the housing.
- Blades, housing and the area around the motor are degreased with care.
- It’s closed up, run and checked, and pictures go into your report.
How to prepare
- Clear loose items from the work area
- Let us know when the site is closed or quiet
- Make sure equipment near the work can be switched off and left to cool
How to get a quote
Some systems can be priced from photos; others need a survey. Larger sites, and anything hidden behind walls, ceilings or floors, are normally surveyed first. Either way, you get a fixed price before work begins.

Your questions about extract fan cleaning in Porter's End
Which fire and rescue service is responsible for Porter's End?
It’s Hertfordshire Fire and Rescue Service, which covers Porter's End. 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.
Do you work at weekends in Porter's End?
Yes, out-of-hours work is a big part of what we do. Your customers, staff or residents in Porter's End needn’t be disturbed. Your opening times are the first thing we ask for.
Can one contract cover all our sites?
Yes. Our area covers London and the South East, so we can schedule a run of sites as one programme. Each site gets its own report and photos.
Can you fix a fan that’s worn out?
We also repair and replace extract fans. If cleaning shows a worn motor, bearings or impeller, we will tell you and quote for the repair.
Do you have a 24/7 line?
Yes, any time. For anything urgent, such as a fan failure or damage after a fire, ring the 24/7 line, and we will advise on what to do next.
How long is a fan clean?
It takes an hour or two for most single fans. Your quote will give an idea.
How often does the fan need cleaning?
At least as often as the rest of the extract, which BESA guidance sets by daily cooking hours: from 3-monthly for heavy use to 12-monthly for light use. Some fans need attention sooner.
Are you insured?
Yes. We’re fully insured, and the details are available on request.
What we are called out for in Porter's End
How fast a fan gets greasy in Porter's End depends on the cooking: how many hours a day the kitchen runs and what it cooks. BESA guidance sets minimum intervals of 3, 6 or 12 months for the whole system by daily use.
Common reasons sites call us include:
- Vibration from an unbalanced impeller
- A smell of hot grease from the extract
- Less air being pulled from the kitchen
- A fan motor running hot under a coat of grease
Volunteers running a hall kitchen near St Peter, or anywhere in Porter's End, may not know when the extract was last cleaned, and a grease test settles it.
