Affordable window cleaner required

[immyp]

Looking for a window cleaner who doesn't overcharge. I've had a great window cleaner who charged a reasonable £40 to do all the outside windows, but sadly he's now retired. The quotes I've had recently have been around the £70+ mark which seems pretty steep for 30-40 minutes! I checked Checkatrade who say the average cost should be £35-£45 for up to an hour of window cleaning, so if anyone can recommend one, I'd really appreciate it. Thanks.
