Commercial Oven Cleaning: A Complete Guide for Restaurants, Pubs & Cafés
For restaurants, pubs, and cafés, a clean kitchen isn't just about appearances — it's a legal requirement. Here's everything hospitality businesses need to know about commercial oven cleaning.

Why Commercial Oven Cleaning Matters
In a commercial kitchen, cleanliness isn't optional — it's a legal requirement. Environmental Health Officers (EHOs) inspect commercial kitchens regularly, and grease build-up in ovens, extractors, and ducting is one of the most common reasons businesses receive poor ratings or face enforcement action.
Beyond compliance, regular commercial oven cleaning:
- Reduces fire risk (grease is highly flammable)
- Improves equipment efficiency and lifespan
- Prevents cross-contamination and food safety issues
- Creates a better working environment for staff
- Reduces energy costs (clean equipment heats faster)
What EHO Inspectors Look For
When an Environmental Health Officer inspects your kitchen, they'll check:
- Oven and range cleanliness — Interior surfaces, door glass, and seals free from carbon and grease
- Extractor hoods and filters — No excessive grease build-up; filters clean and functional
- Ductwork — Accessible and free from grease accumulation (a major fire risk)
- Refrigeration — Clean, defrosted, and free from mould or odours
- Microwaves and combi ovens — Interior, door seal, and exterior clean
- Documentation — Cleaning schedules, COSHH records, and maintenance logs
A failure in any of these areas can result in a Food Hygiene Rating of 1 or 2, which can seriously damage your reputation and custom.
How Often Should Commercial Kitchens Be Cleaned?
The frequency of commercial oven cleaning depends on your kitchen's volume:
- High-volume kitchens (busy restaurants, pubs, takeaways) — Deep clean every 4–6 weeks
- Medium-volume kitchens (cafés, small restaurants) — Deep clean every 8–12 weeks
- Low-volume kitchens (care homes, schools, offices) — Deep clean every 3–4 months
Extractor hood filters typically need degreasing every 2–4 weeks in high-volume kitchens, as they collect grease rapidly during service.
What's Included in a Commercial Oven Clean?

Scheduling Around Your Business
We understand that commercial kitchens can't simply shut down for a day. That's why we offer:
- Flexible scheduling — Early morning, evening, or overnight cleans to minimise disruption
- Weekend availability — For kitchens that operate Monday to Friday
- Phased cleaning — We can clean different sections on different days
- Recurring contracts — Scheduled cleans at regular intervals so you never have to think about booking
Fire Safety and Insurance
Grease build-up in commercial kitchen extractors is one of the leading causes of kitchen fires. Many insurance policies require evidence of regular professional cleaning as a condition of cover. Without it, a claim following a fire could be denied.
Our cleaning service includes:
- Before and after photos (for your compliance records)
- Detailed cleaning reports
- Certificates of completion (for insurance and EHO purposes)
Commercial Cleaning Pricing
Unlike residential cleaning, commercial work is priced individually based on:
- The number and type of appliances
- Kitchen size and accessibility
- Condition and level of soiling
- Frequency of cleaning (one-off vs contract)
All commercial work is quoted following a site inspection to ensure fair and accurate pricing. Contact us to arrange a free site survey and quote.
