I see they've started responding to the negative reviews...

Yeah Basically they're saying it's been eight years since they've increased their prices.
You know what guys I actually think it's reasonable
I'm not saying I'm happy to pay more.
But don't you think some of us are acting like those customers who aren't happy with a 50p or £1 price increase after 2 years? On a £10 job every 3 years £1 is about £13.00 today. They're increasing by 20p over 8 years on say a £10 job.. the percentage of increase by a window cleaner is higher then what they are increasing. I hope this makes sense what I'm trying to say.
In a nutshell upping prices after 8 years by such a small amount isn't really that much to worry about.
If it does bother you that much just pass the cost on I really think no one's going to complain if you announce a 20 pence increase to a £10 job likewise 40p to a £20.
By the time they want to increase prices again in another 8 years by the looks of things you would have increased probably two or 3 times..
