Kitchen deep cleaning in Welwyn Garden City
We clean from the ceiling down. Ceilings and high-level areas come first, followed by walls, equipment and floors so dirt does not land on areas already done. Cooking equipment is switched off and allowed to cool first. Typical jobs include grime in corners that pests could exploit and a clean-up ahead of an inspection, across ranges and ovens, walls and ceilings and fryers and grills.
Around a town like Welwyn Garden City, the kitchens we deep clean tend to be pubs, restaurants, takeaways and school or care home kitchens. Each builds up grease where the daily clean cannot reach.
Insurers, fire officers and environmental health officers all look at records. So every job comes with a written report and photos, and grease extract cleans come with a TR19® certificate issued through the BESCA Vent Hygiene Elite portal.

Welwyn Garden City questions
Can you come to Welwyn Garden City after we close?
Yes, we can come after you close and finish before you open. It means the site in Welwyn Garden City keeps running as normal. Let us know the hours you’re closed and we will book within them.
Can school kitchens in Welwyn Garden City be cleaned in the holidays?
Yes, and it’s the easiest time to do it. There are about 21 schools, colleges and universities on the FSA’s food hygiene register within about 1.5 miles of Welwyn Garden City. Booking early in the term gives the best choice of holiday dates.
Can you clean behind fixed equipment?
We clean behind and under as much equipment as can be safely reached. Where an item is fixed we clean around it as fully as we can.
What accreditations do you have?
Duct Doctor is a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. CHAS, SafeContractor and ISO 9001 are in place too, and we are fully insured.
What does commercial kitchen deep cleaning cost?
Size, equipment and the level of build-up all affect the price. Send us photos or details, or we can visit and give you a fixed price.
Is there anything we have to do beforehand?
Very little. Move food and loose items away from the areas being cleaned, and make sure we can get in at the agreed time.
What do you do with what you remove?
Anything we remove is contained as we work and taken away with us, from grease and debris to used cleaning water. We don’t leave it behind.
Is there a survey before the work?
Yes. We always survey first, from your pictures and details, or with a visit where necessary. A fixed quote follows.
How it works
Your trading hours come first. We book the visit for a time the area is closed, whether that is an evening, overnight or a weekend. When the team arrives, the work area is protected and the relevant equipment is switched off to cool, and the job takes one overnight or weekend visit for many kitchens, longer for large sites. Parking in a town like Welwyn Garden City is normally straightforward, so the main questions are access and timing.
- A pre-clean look round tells us what’s needed.
- Areas are protected and equipment is made safe.
- Grease is removed from ceilings, walls and equipment.
- Behind and under the equipment is cleaned where it can be moved safely.
- The floor is cleaned and the kitchen left ready for service.
Preparing for the visit
- Agree a time when the area can be out of use
- Dig out any earlier paperwork for the system
- Name a contact who can let us in at the agreed time
Get a fixed quote
To get a fixed quote, call 0345 646 2711 or email us and tell us the type of site, your opening hours and roughly what the system looks like. Photos and the last report, if you have one, make the quote quicker. We normally come back within one working day.
Advice
For landlords and multi-site operators
Where a tenant occupies the premises but the landlord owns the building, it’s worth checking the lease for who maintains the systems. We are happy to deal with either side, and the report can go to both.
Whether it’s one building or many, you get the same standard: diagnosis, a fixed price, work booked around your hours and a written report with photos.

What happens if it’s left?
Old grease hardens and bonds to surfaces. Regular deep cleans are easier than rescuing a neglected kitchen, and surfaces last better. A small fault found now is a quick job; the same fault found later can close the site.
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 send us an email, and we will talk you through it.

Walls and ceilings
Ceilings above the cooking line often darken with grease. They’re cleaned as part of the deep clean using methods suited to the surface.

Looking after it afterwards
How long the results last depends on use and care. We suggest:
- Do not let the extract cleaning slip
- Clean spills while they’re fresh, before they bake on
- Keep a cleaning schedule and record it
- Book deep cleans on a regular cycle
Many kitchens book the next deep clean before we leave. Regular deep cleans keep the kitchen consistently clean all year round.
Splashes left on hot surfaces bake on. Regular deep cleans clear them before they harden and protects the surfaces.
What affects the cost of kitchen deep cleaning
We do not publish a price list, because sites vary so much. The quote depends on:
- Access, including roofs, risers and ceiling voids
- Site requirements such as sign-in and permits
- Parking and loading at the site
- The size of the system
No two sites are the same, 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
Before you ask for a quote, gather:
- The site address and the type of premises
- Your opening hours and when the area is out of use
- A few general shots of the system
- How we’d reach plant on a roof or in a plant room
Quotes are quick. Send a few details and pictures, and we typically reply with a fixed quote within one working day. If we need to see the system first, we book a survey around your hours.
