What should you check before buying?
First, work out whether you can actually install a separate appliance, then compare the load you need to dry with the cycle times. If you can only fit one machine, look at the washer-dryer’s full cycle rather than its washing specifications alone.
Separate tumble dryer
Consider this if: you have a suitable space and regularly dry several loads.
Bear in mind: a second appliance takes up space. If you’re stacking the machines, the kit must be suitable for both models, as specified in the manufacturer’s instructions.
Washer-dryer
Consider this if: there’s room for only one machine in your flat and its drying capacity is enough for your laundry.
Bear in mind: its drying capacity is lower than its washing capacity. UFC-Que Choisir also notes that drying takes longer than with a conventional tumble dryer, and that water use is worth checking.
| Consideration | What to check | Who this matters to |
| Load size and frequency |
Compare drying capacities in kg with the amount of laundry you dry per cycle. With a washer-dryer, don’t confuse its washing capacity with its drying capacity. |
If I do laundry often or have large loads, I want to know how much will be dry after one cycle without splitting every load. Around 34% of shoppers make this a priority. |
| Available space |
Measure the alcove, access routes and depth with the door open. If stacking the machines, check that the kit is compatible with both model numbers. |
If I only have space for one appliance, installing two machines is only an option if a suitable stacked set will fit. This is the top consideration for around 33% of shoppers. |
| Drying time |
Check the duration of the programme for the load you have in mind and, for a washer-dryer, the length of the full wash-and-dry cycle. |
If I need to get through several loads, I want to know when the laundry will actually be dry before choosing a machine. Cycle time is the top consideration for around 20% of shoppers. |
| Energy use and venting |
Compare electricity use and, for a washer-dryer, water use for the full cycle. If you’re considering a vented model, check the vent and the requirements in its instructions. |
I want to keep running costs under control without choosing an appliance that can’t be vented properly in my home. Around 13% of shoppers put these practical requirements first. |
When comparing technologies, UFC-Que Choisir describes heat pump tumble dryers as using less electricity than conventional condenser or vented models, which are generally quicker. These are broad trends, so check the figures and cycle times for the specific model you’re considering. Only consider a vented tumble dryer if your installation and home ventilation meet the requirements in its instructions.

Frequently asked questions
Can a washer-dryer dry the whole load it has just washed?
Not if the wash load is larger than its drying capacity. For example, Electrolux and LG list models with respective wash/dry capacities of 10/6 kg and 11/6 kg. If you have more than 6 kg of laundry to dry, you’ll need to remove some of the load and run another cycle.
How do you compare the energy use of two washer-dryers?
For each model, compare the figures for the full wash-and-dry cycle separately from those for washing alone. The European Commission says the label includes information such as energy use, water use and cycle duration. Make sure you compare figures for the same type of cycle before choosing between appliances.
Can you stack any washing machine and tumble dryer?
No. Compatibility depends on the models and the kit recommended by the manufacturer. Bosch’s instructions for the WTH8300SFR tumble dryer require a suitable stacking kit. Note down both model numbers and check the installation instructions before planning a stacked setup.
Is a vented tumble dryer suitable for a flat?
Only if the model and your home allow it to be vented as described in its instructions, without compromising ventilation. Check the route for the vent and, if changes to your home are needed, confirm they’re possible before you buy.
What maintenance should you plan for after installation?
Follow the instructions for your chosen model. For a condenser or heat pump tumble dryer, check how to manage condensed water and maintain the filters. For a washer-dryer, refer to the manufacturer’s cleaning instructions and any recommended maintenance cycles.
