Common questions in Colney Street
Is Colney Street within the area you cover?
Yes. Villages and rural sites across the South East are part of our work, Colney Street included. Just mention lanes, gates or anything else about the site when you book.
Which council inspects kitchens in Colney Street?
That’s St Albans City council, whose environmental health officers carry out food hygiene inspections in Colney Street. It helps to keep the extract cleaning records with your food safety paperwork, so they’re ready if asked for.
What should I send you?
A short description and a few photos plus the address and your hours. If we need more, we will ask.
How far ahead should we book?
It depends on the time you need and how big the job is. Mention your preferred dates with your enquiry, and for anything urgent, ring our 24/7 emergency line.
Can you look after several sites?
Yes. One number covers all your sites across London and the South East, and visits can be set on a regular cycle.
Who has the legal duty for fire safety?
Under the Regulatory Reform (Fire Safety) Order 2005, it’s the responsible person: often the employer, owner or occupier. Landlords, facilities managers and managing agents can also hold responsibility.
Do you look at the system first?
Yes. Every job is surveyed first, either from pictures and details you send or on a site visit. A fixed quote follows.
Can we book visits on a schedule?
Yes. Plans on a 3, 6 or 12-monthly cycle are available, to suit the system and how it’s used.
How we handle extract fan cleaning in Colney Street
In Colney Street, as everywhere we work, the fan follows a set routine: isolated first, then opened, scraped and degreased. The result is photographed for your records. If you have a noisy fan that has got louder over time and a fan coated in grease inside its housing, we can help, from in-line fans, roof-mounted fans and centrifugal fans onwards.
Somewhere as small as Colney Street, 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.
A written report with pictures follows each visit, so you have a record of what was done and when. Where the work is a TR19® Grease clean, the certificate is issued through the BESCA Vent Hygiene Elite portal.

What affects the quote in Colney Street
Your quote is based on your site. We take into account:
- Whether it’s a one-off visit or part of a schedule
- What state the system is in
- The size of the system
- Whether we need access equipment or extra panels
The cost depends on the size of the system, the condition it’s in and how easy it is to reach. You get a fixed price before work begins, so you know where you stand.
What to send for a quote
To help us quote quickly, send us:
- Photos showing the whole system and its surroundings
- The times we could work without disrupting the site
- Where the site is and what kind of site it is
- How we’d reach plant on a roof or in a plant room
Photos are enough for some jobs, while others need a look on site. Larger sites, and anything hidden behind walls, ceilings or floors, are normally surveyed first. Either way, the quote is fixed before any work is booked.
Multi-site and managed buildings
Running several sites is easier with one contractor. We work across London and the South East, so visits at different addresses can be planned together and kept to a regular schedule.
Records are where multi-site compliance often slips. Each visit produces a dated report with pictures, so you can show an insurer or inspector what was done at each site.
Looking after it afterwards
Once we have finished, these simple steps help:
- Note any drop in extraction at the canopy
- Report grease escaping from the fan
- Do not store items in front of the fan’s access point
- Do not turn the fan off mid-service
When we have finished, the fan is reassembled and run. If anything seems wrong, from vibration to wear, we note it, so you can plan any repair.
Keep the whole system on its cleaning cycle. A fan cleaned with the rest of the system on time rarely gets badly coated, in line with BESA guidance.
What we do, step by step
Our technicians bring everything the work needs, from protective sheeting to tools and access equipment. All we need from you is clear access and the right equipment switched off. The visit takes an hour or two for one fan, longer when it’s hard to reach. Photos of the system and how to reach it help us plan a visit to Colney Street.
- We start by checking where the fan sits and how to isolate it.
- The fan is isolated so it cannot start while we work.
- We remove the grease from the blades, impeller and casing.
- The fan and its surrounds are degreased, keeping clear of the motor’s electrics.
- It’s closed up, run and checked, and photos go into your report.
Getting ready for the visit
- Dig out any earlier paperwork for the system
- Move anything stored near the system
- Arrange a key holder or contact on site

Colney Street kitchens: local notes
Food Standards Agency records list about 17 restaurants, cafés and works canteens and about 7 takeaways within about 1.5 miles of central Colney Street. Where they cook under a canopy, an extract fan is pulling grease-laden air through its blades every service. Kitchens in Colney Street get their food hygiene inspections from St Albans City council. An officer looking round a kitchen will see the canopy, and grease there is hard to miss. Keeping each certificate and photo report on file helps show the extract is looked after. Fire safety in Colney Street falls to Hertfordshire Fire and Rescue Service. The Fire Safety Order puts the duty on whoever runs a kitchen to control its fire risk, and a greasy duct is fuel.
Healthcare kitchens, like those at hospitals such as Kingsley Green (about 1 mile east), often cook for long hours, which puts them in BESA’s heavier-use bands. Older buildings often hide long, awkward duct runs, and if you run a kitchen at a historic venue in the area (High Elms Manor is about 2.9 miles west), access may need planning. Term dates shape school work: for a school like Park Street Church of England Voluntary Aided Primary School, an extract clean fits neatly into a half-term or summer break.

What staff can safely do
Staff cleaning does not replace a specialist visit; it supports it. Regular in-house cleaning slows the build-up, but the parts you cannot see still need a specialist at the right interval.
Away from the kitchen, the in-house job is mainly checking: keeping grilles clear, noting unusual noise or smells and logging filter changes. The inside of ducts and units needs a specialist.

What the work involves, part by part
Roof-mounted fans
Roof fans sit at the top of the riser. We clean them where they can be safely reached, with any limits noted.
Impellers and blades
Grease on the leading edges of the blades cuts the fan’s efficiency. Scraping and degreasing them restores their shape, so the fan can run as intended.
Why deal with it now?
Grease on a roof fan can also escape outside. It marks the area around the outlet and leaves more fuel outside, which is one more reason to keep it clean. Our emergency line runs 24/7, but a planned visit to Colney Street is calmer for everyone.
We do not list prices on the website, because each job is priced on what it involves. For a fixed quote, call us on 0345 646 2711 or drop us a line, and we’ll explain what it covers.
