Pull the bottom drawer out of your oven in a Harrow kitchen and you will usually find the same thing: a layer of carbonised fat that no supermarket spray will shift. We take that off properly, by hand, in dip-tank chemistry that does not stink the house out.
Last updated April 2026. Written by the team at Monster Cleaning Ltd, trading across north-west London since 2014.
Monster Cleaning does oven cleaning in Harrow from £77 for a single oven, with same-day use because our dip tank is non-caustic.
That is the short version. Below is how the job actually runs, what each appliance costs, and a few honest notes about cleaning ovens in this particular corner of HA1, HA2 and HA3.
What oven cleaning costs in Harrow
Flat prices. No survey, no quote, no surprise on the doorstep. You tell us the appliance, we tell you the number, and that is what you pay.
A single oven is £77. A double oven is £110, which covers the main cavity and the second cavity or grill together. A 90cm range cooker is £114, and a traditional two-oven AGA is £143 because it is a slower, heavier job that we never rush. Add-ons are priced the same whether you book them on their own or alongside the oven: a hob is £23 to £28 depending on whether it is gas, ceramic or induction, an extractor is £28, and a microwave is £22.
The reason we can hold a fixed price is that an oven is a known quantity. A four-bedroom end of tenancy is not, but a double oven is a double oven whether it sits in a flat off Roxborough Road or a 1930s semi out towards Rayners Lane. So we do not pad the figure to cover ourselves. If your hob is filthy and your extractor has not been touched in five years, the price is still the price.

How the dip-tank method works
Here is the part most people have not seen. We carry a heated dip tank in the van. The removable bits of your oven, which means the shelves, the side runners, the racks and the fan covers, come out and go into the tank. The solution lifts off baked-on grease while we hand-clean the parts that cannot be removed. Wire shelves are the worst offenders, because the grease bakes into the joints where no sponge reaches, and the soak is the only thing that gets them properly clean rather than just smeared about.
Our tank chemistry is non-caustic. That matters for two reasons. The first is the fumes, or rather the lack of them: a caustic soda bath gives off a sharp smell that lingers, and in a small Harrow flat with the windows shut against the cold that is genuinely unpleasant. The second is the same-day use. Because the chemistry is gentler, you can switch the oven back on as soon as we leave and cook your tea that evening. No 24-hour wait, no airing the kitchen out.
The glass gets done too. We separate the inner door panels where the model allows it and clear the brown film that builds up between the layers, the bit you can see but never reach. Then the cavity, the seals, the trim, and a wipe-down of the front so it looks right from the outside as well as clean within.
Harrow kitchens, honestly
We clean a lot of ovens up the hill and across the town centre, so a few patterns repeat. The Victorian and Edwardian terraces south and west of Harrow-on-the-Hill tend to have narrow galley kitchens where the cooker is wedged tight against a wall, which is fine, we work around it. The inter-war semis out through Kenton and the Harrow Garden Village streets near Rayners Lane more often have a freestanding range or a double oven in a fitted run.
Then there is the water. Harrow sits in a hard-water zone supplied by Affinity Water, and limescale is a fact of life round here. It does not attack the oven cavity the way it furs up a kettle, but it shows on the hob, on the splashback and on any glass near the sink, so when we clean a hob we are often clearing scale as much as grease.
Parking is the other real-world bit. Around the St Ann’s Road and St George’s centre end of town the controlled bays fill fast, and a chunk of the streets off Lowlands Road and Greenhill are permit-only during the day. Tell us when you book and we will sort the logistics; if there is genuinely nowhere to stop, the dip tank is portable enough that we adapt. Most of central Harrow is a short hop from Harrow-on-the-Hill station anyway, which is how half our team gets about.
The newer flat blocks behind the station are their own small puzzle. Compact fitted kitchens, often a single built-in oven at chest height, and a lift to factor in when we carry the kit up. None of it slows the clean down; it just means we plan the access before the van leaves.
One more thing worth saying plainly.
Landlords near the station book us constantly between tenancies, because a clean oven is one of the line items that decides a deposit, and the oven is the appliance check-out inventories single out more than any other.

What we clean, and what we do not
We clean domestic ovens of every common type. Built-in single and double ovens, freestanding cookers, range cookers up to 90cm, two-oven AGAs and Range-style cast-iron ovens, plus the appliances that sit around them. The list of add-ons is short on purpose:
- Hobs, gas or ceramic or induction, £23 to £28.
- Extractor hoods and the metal filters inside them, £28.
- Microwaves, including the turntable and the roof plate, £22.
What we do not do is pretend a dead oven is a dirty one. If your element has gone or your fan has packed up, cleaning it will not bring it back, and we will say so rather than take the money. We are cleaners, not an appliance repair firm, and we would rather you knew the difference before we start. The same goes for self-cleaning liner panels inside some ovens: we clean around them by hand rather than scrub the coating off, because once it is gone it does not come back.
Booking, timing and where we cover
Booking is a phone call or an email, not a form that takes a week. Ring 0333 555 2076 or email [email protected] with your postcode and what needs doing, and we will give you a slot and the exact price in the same conversation. Most single ovens take between ninety minutes and two hours; a neglected double or an AGA takes longer, and we book the time for it rather than clock-watching.
We cover Harrow town centre and the wider HA postcodes around it, from Harrow-on-the-Hill and Greenhill through Kenton, North Harrow, Rayners Lane, Wealdstone and Harrow Weald. If you are on the edge of the borough and not sure, just ask.
If you are moving out, the oven is usually part of a bigger job. We also handle end of tenancy cleaning in Harrow, and if the carpets or the rest of the home need attention we run Harrow carpet cleaning and regular domestic cleaning in Harrow as well.

Frequently asked questions
How much does oven cleaning cost in Harrow?
A single oven is £77 and a double oven is £110. A 90cm range cooker is £114 and a traditional two-oven AGA is £143. Add-ons: a hob is £23 to £28, an extractor is £28 and a microwave is £22.
Can I use the oven the same day you clean it?
Yes. Our dip tank is non-caustic, so there is no waiting period and no lingering smell. You can switch the oven back on and cook the evening we finish.
Are the cleaning products safe and low-odour?
They are. We use a non-caustic dip-tank solution rather than harsh caustic soda, so there is no sharp chemical smell left in the kitchen, which matters in a small flat with the windows shut.
How long does an oven clean take?
Most single ovens take ninety minutes to two hours. A neglected double oven or a two-oven AGA takes longer, and we book the extra time rather than rushing the job to fit a schedule.
Do you clean the oven door glass?
Yes, including between the panels where the model allows the inner door to be separated. That brown film you can see but never reach gets cleared along with the cavity, seals and trim.
Do you clean hobs, extractors and microwaves too?
We do. A hob is £23 to £28 depending on whether it is gas, ceramic or induction, an extractor hood is £28, and a microwave is £22. The price is the same booked alone or with the oven.
Which parts of Harrow do you cover?
Harrow town centre and the surrounding HA postcodes: Harrow-on-the-Hill, Greenhill, Kenton, North Harrow, Rayners Lane, Wealdstone and Harrow Weald. If you are on the borough edge, just ask when you ring.
Can you clean a range cooker or an AGA?
Yes. A 90cm range cooker is £114 and a two-oven AGA is £143. Cast-iron ovens are a slower job and we price and time them accordingly rather than treating them like a standard built-in.
Do I need to do anything before you arrive?
Nothing beyond switching the oven off so it is cool to work on, and clearing a little space around it. We bring the dip tank, the solution and all the kit. We tidy up after ourselves before we leave.
What if I am not happy with the clean?
We put it right. Every oven clean is backed by our re-clean guarantee, so if something is not up to scratch we come back and sort it. A fixed price is no use to you if the result is not right.
Is there a parking charge added to the price?
No. The price you are quoted is the price you pay. Some central Harrow streets near St Ann’s Road are permit-only by day, so we sort the parking logistics ourselves when you book.
