Let the oven go cold overnight, take out anything stored in it, clear the hob and a stretch of worktop, and sort out parking close to your door. Those few things keep the visit on time. Afterwards, a wipe with hot soapy water once the oven has cooled after each cook does more than any product, and three surfaces (catalytic panels, the door glass and the door seal) need gentler handling than the rest.
The night-before checklist
- Last cook finished early, so the oven is cool by the morning. A grill used at breakfast can still be hot mid-morning, so skip it on the day.
- Pizza stones, roasting tins, baking sheets and anything else you keep in the oven or its drawer taken out.
- Pans and the kettle off the hob, and one stretch of worktop clear.
- Parking arranged: a space on the drive, a visitor permit, or the nearest bay noted.
- A working socket within reach of the oven.
- An AGA switched off the night before.
- Pets in another room, since the front door opens and closes through the visit.
Why the oven has to be cold
The cavity, the fan cover and the door glass are degreased by hand, so the metal has to be cool enough to work on. Manufacturers ask the same of owners: Bosch's UK cleaning advice starts with making sure the oven is switched off and cool, and its manual for the HBG6764 oven warns that oven cleaner used in a warm cavity can damage the enamel. We need the appliance cool on arrival; a warm one adds waiting time.
An AGA is the extreme case. It is a cast-iron, heat-storage cooker, and AGA's user guides for its gas and oil models ask owners to switch it off the night before a service so that it has cooled by the morning. A clean needs the same night off. The AGA care guide covers the cooker in more detail.
Preparation by oven type
| Oven | Cool by | Also worth doing | Time on site |
|---|---|---|---|
| Built-in single | Morning, after a last cook the evening before | Empty the cavity and any storage drawer | About 90 minutes |
| Double oven | Morning, both cavities and the grill | Empty the top oven too | About 2 hours |
| 90cm range cooker | Morning, every cavity and any griddle | Clear the floor in front of it | 2 to 3 hours |
| Two-oven AGA | Switched off the night before | Nothing left on the top plate or in the ovens | About half a day |
The price is set by the type of oven and fixed on the phone before the visit: a single is £77, a double £110, a 90cm range £143 and a two-oven AGA £143. Every appliance is on the price list.
Parking close to the door
The team needs somewhere to park, and some teams have a heated tank on the van that they use when they can park close; otherwise everything is done in your kitchen. The price is the same either way, and you can ask which applies when you call. If your street is in a controlled parking zone, a visitor permit or the location of the nearest pay-by-phone bay saves time on the day; mention it when you book on 020 8077 5225. If access changes after booking, a call the day before helps.
What happens on the day
- Dust sheets go down in front of the oven.
- Racks, trays and side runners come out and are soaked and cleaned separately.
- The door is split where its design allows, so the glass can be cleaned on its inner faces.
- The cavity, fan cover and door glass are degreased by hand.
- Everything goes back together, the oven is heated, and you look inside before we pack up.
If a corner is not right when you inspect the lit oven, we put it right before we leave. The professional oven cleaning page has more on the method.
Keeping the oven clean afterwards
The habit that matters is small and frequent. Bosch's HBG6764 manual says to clean the cavity after each use so that dirt cannot bake on, and to remove splashes of grease, starch and egg white straight away. Once the oven has cooled, a cloth wrung out in hot soapy water over the floor and the inner glass is enough. The same manual warns that fruit juice dripping from a baking tray leaves stains that cannot be removed, so a deep tray under a juicy pie protects the enamel.
Do not line the oven floor with foil. Bosch says not to cover the floor with any sort of foil or greaseproof paper: heat builds up under it, cooking times go wrong and the enamel is damaged. Foil touching the door glass can discolour it permanently.
- Catalytic panels
- The self-cleaning coating on the back or side walls of many ovens. Which? says it absorbs grease while the oven is hot and breaks it down so it is easier to wipe away. Bosch and NEFF manuals say never to use oven cleaner on it, and Which? advises no cleaning products on catalytic walls at all.
- Door glass
- Bosch's advice is to work on a cold oven, lay a removed door on towels on a flat surface, and use a degreaser left for 5 to 10 minutes. No glass scraper and no glass cleaner.
- Door seal
- Keep it clean: Bosch says a very dirty seal stops the door closing properly. Its manual also says not to scrub the seal or take it off.
- AGA enamel
- AGA's guides say no oven cleaner and no abrasive pads; a daily rub with a damp soapy cloth, then a dry one.
When to book the next clean
That depends on how much you roast and how well the daily wipe holds up. Our guide to how often to clean an oven works through the signs to watch for. Rebooking is the same phone call, with the price fixed before anyone comes out.
Questions before the visit
What if the oven is still warm when you arrive?
A hot cavity adds waiting time, so the visit takes longer. Skipping the breakfast grill avoids it.
Do I need to clean the oven first?
No. Leave it as it is; just empty it and let it cool.
Do I need to stay in for the whole visit?
Someone needs to let us in, and someone needs to look inside the lit oven at the end. In between, carry on with your day. For an empty rental, landlords and letting agents can arrange a key pick-up.
Can I cook in it the same evening?
Yes. The oven has been heated with you looking in before we leave.
