After-Hours Kitchen Extraction Cleaning in London
Quick answer: Yes. Duct Clean London cleans commercial kitchen extraction after hours, including evenings, overnight and weekends, across North West, West and Central London. We start once cooking equipment is off and cool, clean the canopy, filters, ductwork and fan, and leave the kitchen ready for the next service, with photos and a report.
Why clean extraction after hours?
- No lost trading: the kitchen stays open for every service.
- Safer working: appliances are off and cool, and there are no staff or customers in the work area.
- Better access: worktops, ceilings and roof areas can be cleared without getting in anyone’s way.
- Building rules: many London offices, shopping centres and residential blocks only allow noisy or roof work at set times.
Typical after-hours time slots
| Premises | Usual window |
|---|---|
| Restaurants and takeaways | After the last service, often from 11pm or midnight |
| Hotels and 24-hour kitchens | Quietest overnight period, cleaned in sections |
| Office canteens | Evenings and weekends. See office kitchen cleaning. |
| Schools and colleges | Holidays, half-terms or weekends. See school kitchen extraction cleaning. |
What happens during an after-hours clean
- Arrival: we confirm the agreed scope and check appliances are off, isolated and cool.
- Protection: we cover cooking equipment and floors.
- Measure: pre-clean grease readings and photographs.
- Clean: canopy, filters, plenum, accessible ductwork, fan and discharge.
- Measure again: post-clean readings and photographs from the same positions.
- Handover: filters refitted, area tidied, and the kitchen ready for morning prep.
The report records what was cleaned, any areas we could not reach and when the next clean is due. See TR19 cleaning and reporting.

Frequently asked questions
Can kitchen extraction be cleaned overnight?
Yes. Duct Clean London cleans kitchen extraction in the evening, overnight and at weekends so restaurants, hotels and canteens do not lose trading time.
How long does an after-hours extraction clean take?
Most single-canopy restaurant systems take one night. Larger or multi-canopy systems may be split across several visits.
Does after-hours cleaning cost more?
It can, depending on timing, access and building rules. We agree the price and working window before booking.
Will the kitchen be ready for the next morning?
Yes. Filters are refitted and the work area is cleaned and handed back ready for prep, unless we agree otherwise in advance.
