Washing Machines: New Energy Ratings Explained – What Do A, B and C Really Mean?

If you’ve been shopping for a new washing machine recently, you may have noticed something surprising — very few models are rated A.

Instead, most machines now fall into the B, C or even D categories. At first glance, that can feel like a step backwards. But in reality, it’s the opposite.

Here’s what’s really going on.

Why did energy ratings change?

The EU introduced a new energy labelling system in 2021 to make ratings clearer and more meaningful.

Previously, most appliances were rated A+, A++ or A+++. Over time, this became confusing — nearly every machine looked “efficient,” making it difficult to compare products properly.

The new system resets everything back to a simple A–G scale:

  • A = most efficient
  • G = least efficient

However, the key detail is this: the new scale is much stricter.

Why are so many washing machines rated C or D?

Because the bar has been raised significantly.

A washing machine that would have been rated A+++ under the old system may now fall into a B, C or even D category under the new one.

So while it might look like machines are less efficient, they’re not — the standards have simply changed.

Is a C-rated washing machine still good?

Absolutely, yes — and this is where many people get caught out.

C-rated washing machines today are still considered energy efficient. In fact, for most households, they represents an excellent balance between performance, price and running costs.

Only a small number of machines currently achieve an A rating, and they tend to come at a higher price point.

What actually affects the energy rating?

Energy ratings are based on several factors, including:

  • Electricity usage per cycle
  • Water consumption
  • Programme efficiency (especially eco modes)
  • Load capacity

Most ratings are calculated using the Eco 40-60 programme, which is designed to minimise energy use — even if it takes longer to run.

Should you only buy A-rated?

Not necessarily.

While A-rated machines are the most efficient, they are often more expensive upfront. For many households, a B or C-rated model offers better overall value.

Instead of focusing only on the letter, it’s worth considering:

  • How often you use your machine
  • Your typical load size
  • The features you actually need

The bottom line

The new energy labels haven’t made washing machines worse — they’ve made the ratings more honest.

So if you’re seeing more C-rated machines than you expected, don’t worry. You’re still looking at modern, efficient appliances — just measured on a much tougher scale.
