Is Professional Oven Cleaning Worth It? Before & After the Numbers

It's the job everyone puts off — and the first thing a letting agent checks. Here's an honest look at what professional oven cleaning involves and when it's worth paying for.

Why DIY oven sprays disappoint

Supermarket oven cleaners are caustic sprays that work on light grease but struggle with carbonised, baked-on deposits — the black crust that builds up over months. They also can't reach between the door glass panels, where drips leave permanent-looking brown streaks.

What a professional clean actually involves

• Racks, trays and (where removable) the door soaked in a heated degreasing solution
• Carbonised deposits scraped and dissolved from the interior without damaging the enamel
• The fan and element area degreased
• Door glass dismantled and cleaned between the panels — the step DIY can't do
• Exterior, knobs and handle polished

The result is genuinely like-new — see our before and after photos.

When it's clearly worth it

At the end of a tenancy. Cleaning-related deposit deductions routinely exceed the cost of a professional clean many times over, and the oven is the most common single cause. If you're booking an end of tenancy clean, adding the oven is the highest-value extra on the list.

Before selling or renting out a property. A spotless kitchen photographs better and signals a well-maintained home.

Once a year at home. A heavily used family oven benefits from an annual deep clean — it heats more evenly, smokes less, and stops setting off the smoke alarm every Sunday.

How long does it take?

A single oven takes roughly 1–1.5 hours; add the hob and extractor hood and it's around 2 hours. Everything is food-safe and the oven can be used the same day.
