Do eco programmes save you money?

How Do They Conserve Energy?

Contrary to what you might expect, eco programmes, despite their longer duration, can indeed reduce energy consumption. With dishwashers and washing machines, the secret lies in their ability to clean effectively with less heated water, thanks to prolonged soaking/soaping times. This approach not only conserves energy but also reduces water usage. The trade-off? It simply takes a bit more time.


When to Use Eco Mode

Eco mode is not always the go-to option. Urgent cleaning needs might prompt you to choose faster cycles. However, for regular use, eco programmes offer a cost-effective solution. Be mindful, though, as heavily soiled items might require more intensive cleaning settings.


The Cost-Saving Potential of Eco Programmes

Measuring the exact savings from eco programmes can be tricky, as it varies by appliance and usage. But let’s take the Miele G7460SCVi dishwasher as an example. 

To start, let's look at the energy consumption data:

  • Eco programme: 0.54 kWh
  • Automatic programme: ~0.75 kWh (varies depending on load)
  • Quick programme: 1.10 kWh

Based on 280 annual cycles, the eco programme can slash energy costs by 39% compared to the automatic setting and an impressive 104% versus the quick cycle. Translating these into annual savings, you could save around £18 against the automatic and £47 against the quick programme, assuming an electricity cost of 30p/kWh. These figures underscore the financial advantages of choosing eco-friendly options.

In terms of water consumption, there is very little between them, you'll save about £1 compared to the automatic setting and £2 compared to the quick cycle (annually).



Yes, eco programmes in dishwashers and washing machines do save you money. They achieve this by using less energy and water through longer, more efficient wash cycles, as evidenced by significant annual cost savings compared to standard programmes.
