The oven in a Chelsea mansion flat tends to get ignored until the smoke alarm goes off mid-roast. By then the door glass has browned over, the base is black, and the smell has filled a galley kitchen that already had one small window and not much air. That is the call we turn up for.
Last updated April 2026. Monster Cleaning Ltd, trading since 2014.
We clean ovens across Kensington and Chelsea from £77, using a non-caustic dip-tank so the appliance is safe to cook the same day.
What an oven clean costs here
The numbers first, because that is what you came for. A single oven is £77. A double oven is £110. A 90cm range cooker is £114. A two-oven AGA is £143. A hob is £23 to £28, an extractor is £28, and a microwave is £22. No call-out fee, no surprise once we are through the door.
Those prices do not change with the postcode. A single oven is £77 in a one-bed off Fulham Road and £77 in a six-storey house on Cheyne Walk. We do not run a Chelsea surcharge, whatever the address does to everything else around here.
Want more than one thing done while we are there? Say so when you book and the prices simply add together. A single oven, a hob and an extractor is one cleaner, one visit, and one total we read out to you on the phone before we set off, so you decide with the figure in front of you rather than after.
How the non-caustic dip-tank clean works
What people dread is the smell. The supermarket oven gels are caustic, they reek for days, and the label tells you to run the empty oven hot before you cook anything, which nobody actually does. We work the other way round.
The cleaner carries a heated dip-tank in the van. The shelves, the side runners, the fan guard and any panels that come out of your oven go into that tank to soak, well away from your kitchen. While they soak in a warm, water-based degreaser, the cleaner scrubs the cavity, the door glass and the rubber seals by hand. Nothing in the process is caustic, so the baked-on carbon lifts without fumes and without stripping the enamel off the inside.
Then it all goes back together. We dry the parts, refit them, wipe down the front and the controls, and check the door still shuts square. Because nothing harsh has touched the cavity, there is no waiting around. Dinner can go in that evening.
The shelves, the side runners, the fan guard and any panels that come out of your oven go into that tank to soak, well away from your kitchen.
There is a second reason it suits the flats around here. The mess stays in the van. In a top-floor mansion flat with one window over the sink, the last thing you want is a tray of caustic gel and an extractor fan roaring to clear it. The dip-tank keeps the worst of the job outside the room.
Kensington and Chelsea kitchens, and their awkward ovens
This borough is mostly flats, and the flats are mostly old. Behind the white stucco fronts off the King’s Road and the red-brick mansion blocks around Cadogan Square sit kitchens that were never drawn for a modern cooker. London’s first purpose-built mansion block, Albert Hall Mansions by Norman Shaw, went up near the Royal Albert Hall in 1879, and a lot of the borough followed that template through the 1880s and 1890s. The legacy is small kitchens with the oven wedged into a tight run.
Mansion-block kitchens are usually galley-shaped, carved out of what was once a back room or a maid’s pantry. The oven sits in a line of units with barely a finger’s width either side, and pulling a freestanding cooker out to clean behind it is a careful two-person job. We expect that and we plan for it.
The stucco terraces are a different shape again. A Chelsea townhouse off Tite Street or Royal Hospital Road might run five or six floors, with the kitchen down in a converted basement and a proper range or an AGA in it. Lovely to cook in. Less lovely to lug a dip-tank down to, which is why we send a cleaner who has done these stairs before.
Then there are the mews. Tucked behind the big streets, the old stable lanes off Cadogan Lane and around Kynance Mews have been flats and little houses for a century, and their kitchens are tiny, with a compact built-in oven at chest height. Different again from the porters’ blocks going up near High Street Kensington, where the ovens are new but the grease is just as stubborn after a winter of being ignored.
One thread runs through all of it. A lot of these homes are second homes, company lets or pieds-a-terre, so an oven gets left for months and then hammered hard over a fortnight when someone is in town. That stop-start pattern bakes on exactly the kind of carbon a dip-tank was built to shift.
Parking and access in SW3 and SW7
Parking is the hard part here.
The Royal Borough controls its bays and single yellow lines from 8:30am to 6:30pm on weekdays, with Saturday mornings caught too in many streets, and the permits went virtual a while back, so they hang off the vehicle registration rather than a paper disc in the windscreen. For a tradesperson with a van full of kit, that is the local tax on every job.
It works out one of two ways for us. Either you arrange a visitor or daily trade permit through the council so the cleaner can park near your door, or we use a paid bay and fold the cost into the price. Tell us which when you book. A resident bay you cannot lend us is no help; a trade permit code is worth its weight.
Access inside is its own thing. Half the mansion blocks have a porter, a lift that needs a fob, and a managing agent who would rather kit was not dragged across the marble in the hall. We keep the gear covered, wipe up behind ourselves in shared parts, and we are well used to signing in at a front desk. None of that is new to us in SW3 or SW7.
If you are close to Sloane Square or South Kensington station, the cleaner can come in by tube and trolley the gear the last few hundred yards. On a bad traffic day that beats the van.
Hobs, extractors, AGAs and range cookers
The oven is rarely the only greasy thing in the room. Booked together, these are one trip and a lot less faff.
A hob is £23 to £28. Gas hobs come apart, so the burners, caps and pan supports soak in the tank with the oven shelves; ceramic and induction tops get the burnt rings shifted without a scratch on the glass. An extractor is £28, with the filters degreased and the visible duct mouth wiped, which is the bit that genuinely catches fire if it is left long enough. A microwave is £22, inside and out, turntable included.
Range cookers and AGAs are their own job. A 90cm range is £114 and a two-oven AGA is £143. An AGA sits hot all day, so the enamel and the heavy cast-iron lids want treating with care rather than attacked. We have cleaned a good few in the big houses near Cheyne Walk, and we never rush them, because a chipped AGA lid is an expensive thing to apologise for.
- Dip-tank
- A heated soak tank carried in the van. Removable oven parts clean inside it, off-site from your kitchen, so no caustic mess ends up in the room.
- Non-caustic
- A water-based cleaning solution with no sodium hydroxide. It lifts baked carbon without the fumes or the curing time, so the oven is safe to use straight away.
- Trade permit
- A daily parking permit the borough issues for work vehicles inside a controlled parking zone. Simpler and cheaper than feeding a paid bay all day.
Booking, and our re-clean guarantee
Booking is a phone call. Ring 0333 555 2076 or email [email protected] with your postcode, the kind of oven you have, and any extras. We confirm the price and a fixed time slot, usually for the same working day. We are Monster Cleaning Ltd, Companies House 9919639, run from 255 Upper Richmond Road West, SW14 8QS.
We are straight about our reviews. Our Trustpilot sits at 3.1 out of 5 across 128 reviews, and we read the unhappy ones. Most of the knocks were about timing on bigger jobs, which is why an oven clean now comes with a set slot rather than a morning-or-afternoon shrug.
And there is the guarantee. If you look the oven over after we have left and something is not right, we come back and redo it, no charge and no quibble. We would sooner re-clean than lose a customer. A firm that has cleaned in London since 2014 does not last by walking off from a streaky door.
If you are moving home, an oven clean drops neatly alongside our end of tenancy cleaning in Kensington and Chelsea, and a lot of tenants book the two together to keep the inventory clerk happy. For the rest of the flat, our carpet cleaning in Kensington and Chelsea and regular domestic cleaning in Kensington and Chelsea cover the carpets and the upkeep. You can also read our wider oven cleaning service for how the dip-tank method works across every appliance.
Oven cleaning in Kensington and Chelsea: your questions answered
How much does oven cleaning cost in Kensington and Chelsea?
A single oven is £77. A double oven is £110. A 90cm range cooker is £114, and a two-oven AGA is £143. Add a hob for £23 to £28, an extractor for £28, or a microwave for £22. The price is the same whether you are off the King’s Road or up in a Holland Park mansion flat.
Do you use caustic oven chemicals inside my flat?
No. We bring a heated, non-caustic dip-tank to soak the racks and panels in the van, and the cleaner works the cavity by hand with a water-based degreaser. There is no caustic stink left in the kitchen, and nothing that tells you to wait days before cooking.
Can I use the oven the same day you clean it?
Yes. Because none of it is caustic, there is no curing time and no harsh residue to burn off first. We dry and refit every part before we leave, so you can cook that same evening.
How long will the oven clean take?
A single oven is usually 60 to 90 minutes. A double, or a range with a separate grill, takes a bit longer. An AGA is a half-day because the cast-iron parts have to be handled slowly, not blasted.
Will you clean an oven in a Chelsea mansion block or a mews house?
Yes, and we do most weeks. The dip-tank stays in the van, so a tight galley kitchen on the third floor of a mansion block is no trouble. For a mews house off Cadogan Lane we just plan the parking first, because the lanes are narrow.
Do you clean the hob and extractor at the same time?
We do, and it saves a second visit. A hob is £23 to £28 depending on whether it is gas, ceramic or induction. An extractor is £28, filters degreased and the duct mouth wiped, which is the part that actually catches light if it is left.
Can you park in the Kensington and Chelsea controlled parking zone?
Usually, with a little notice. The borough controls bays and single yellow lines from 8:30am to 6:30pm on weekdays, and permits are virtual now, tied to the registration. If you can sort a visitor or trade permit we will use it; otherwise we price in a paid bay.
My flat is in a conservation area. Does that change the clean?
Not the oven itself. The borough has more conservation areas than almost anywhere in the country, but those rules govern the outside of the building, not an appliance in your kitchen. Indoors we just stay tidy in the communal hall and lift, which the porter cares about.
Do you clean AGA and range cookers?
Yes. A two-oven AGA is £143 and a 90cm range cooker is £114. You see plenty of both in the bigger houses around Tite Street and Cheyne Walk. AGAs need the enamel treated gently, so we never rush a cast-iron lid.
Is there a guarantee if the oven is not right?
There is. Look at it after we have gone, and if anything is not clean we come back and redo it, no charge and no argument. We would rather re-clean than lose you. Monster Cleaning has run since 2014 and plans to be here next year too.
How do I book an oven clean in Chelsea or Kensington?
Call 0333 555 2076 or email [email protected] with your postcode, the type of oven and any extras like a hob or extractor. We confirm the price and a fixed time slot, usually for the same working day.
Do you clean ovens in rented flats when a tenancy ends?
Often. A clean oven is one of the first things an inventory clerk checks. If you are moving out, an oven clean sits neatly alongside our wider move-out service, and a lot of Chelsea tenants book the two in one go.
