Most reliable oven brands

Our unique reliability ratings, which we compile after surveying thousands of Which? members, reveal how reliable different oven brands are and which brands stay fault-free the longest. 
Jane Darling
We've surveyed oven owners to find out which built-in oven brands are prone to faults, and which will give years of stress-free, reliable service.

We'll also tell you the most common oven faults experienced by owners. Broken oven lights, faulty fans and dodgy door seals are among the top gripes in this year's survey.

You're much less likely to end up with one of these problems if you go for a brand that's scored four or more stars for reliability. We've ranked 13 of the most popular brands, including Bosch, Neff, Siemens and Zanussi, in our brand reliability league table. 

Only logged-in Which? members can view our exclusive reliability ratings in the table below. If you're not yet a member, join Which? to get instant access.

Table notes

Reliability ratings are based on a Which? member survey of 2,373 people conducted in October 2019 and use feedback on members' experiences of the brand that they own. The star rating shows how each brand's reliability score compares to other built-in oven brands. Brands with a rating of less than three stars cannot be awarded Best Buys for individual models. Table correct as of November 2019.

Which oven brand stays fault-free for longest?

You've told us that when you buy an oven you think it should last 13 years, on average, before developing a fault. But our graphic below shows this is often not the case. Compare how long the top oven brand stays fault-free compared to the worst brand and the overall average.

How long will my built-in oven last?

On average, a built-in oven will last between 13 and 14 years. This is based on the experiences of Which? members who told us how long they kept their previous appliance from this brand, before they replaced it, either due to a fault, or because it wasn't working as well as when they first bought it. 

Although the graph below doesn't show a big difference between brands in terms of lifespan, we do know that people often live with a sub-standard appliance for longer than they'd like to because of the expense of buying a new one. We did find there was a significant difference in brand satisfaction - with the top brand scoring 83% and the bottom brand scoring just 59%.

How built-in oven brands compare

Built-in ovens are generally reliable, with an average reliability score of 82% across all brands. But that doesn't mean any oven brand is a safe bet. The best oven brand scored an impressive 92%, while the poorest scored 71%.

If you're looking for an oven that gives you a decade or so of trouble-free cooking, you'll want to pick from the brand that tops our table. With an oven from this brand, there's only a one in 10 chance that it will break down within the first eight years. This brand also has several Best Buys among our listings.

We work out reliability scores based on the proportion of faulty ovens per brand in our customer survey. Faults are weighted, so if a brand has more serious faults it will be given a lower score than a brand that experiences minor (repairable) faults. We also adjust scores according to the age of the oven. Newer ovens that develop faults early on will be more heavily penalised than models that develop a fault further down the line.

Common built-in oven problems

In our survey, we asked Which? members what faults they had experienced with their built-in ovens. Of those that had experienced problems, the most common oven faults are:

  • Oven light broken: 33%
  • Fan not working: 8%
  • Door not closing properly: 8%

Built-in oven repairs

We've investigated what to do about some of the trickier problems you might encounter with your built-in oven, surveying 106 appliance repairers about what advice they'd give for fixing common faults with built-in ovens and other home appliances. 

A broken door seal

  • Repairers’ advice: opinions among repairers were split, with slightly more advising customers to carry out the repair themselves than to get it done professionally or replace the oven.
  • Cost of professional repair: around £60
  • Our advice: It’s worth trying to repair it yourself – you can buy replacement door seals online, typically for between £10 and £30.

A grill element not heating up

  • Repairers’ advice: repairers were most likely to say that you should pay a professional to fix this.
  • Cost of professional repair: around £60
  • Our advice: Call in a professional appliance repairer. 

A fan that isn’t turning due to an electrical fault

  • Repairers’ advice: there wasn’t a clear consensus among the repairers we asked, but they were most likely to advise getting it fixed by a professional. Around three in 10 said that they would advise replacing the oven
  • Cost of professional repair: around £50
  • Our advice: Call a repairer, and be prepared for the possibility of replacing the oven if it turns out to be a serious fault.  

Oven reviews you can trust

You can't tell which ovens will cut the mustard in the kitchen based on looks alone. When we test ovens, we time how quickly each one heats up, and measure how good it is at spreading heat evenly and maintaining the correct temperature. We bake cakes and shortbread to see if good stats equate to great bakes. We also check out oven capacity, to see how much you can really fit in, as well as assessing how easy each model is to use and whether it's easy or a nightmare to clean.

On top of this, any oven brand must achieve a three-star reliability rating, as a minimum, in our yearly reliability survey  for it to have any Best Buys. We think that if owners suffer regular breakdowns with their oven, then we can't recommend that brand.

Which? is independent - we work for you, the consumer, so you can be sure that our product recommendations are influenced only by our test results. We don’t take advertising and we buy all the products that we test ourselves, so our advice helps you to make the right choice first time and avoid costly mistakes.
