Got to go with your own gut feeling on this as you'll get loads of differing advice all of which is probably right in it's own way. I was like Dazmond, in the middle of putting them up when lockdown started so paused it. I've now informed the remainder it's going up and in about 2 and half weeks will have finished cleaning everyone at the new price. I only lost one custy (so far) and found most were half expecting it as everythings going up. So relieved I did but my personal gut feeling is that I've done it just in time. If you start informing customers now then we're into october/November before your cleaning at the new price, not a great time for wc even without covid about. Clocks will have gone back, weather should be worse, Xmas round the corner, etc Throw covid into the mix, and anyone furloughed who's on a monthly contract who's about to be finished will be getting their notice in about a weeks time, another 4 weeks and those on a weekly notice wi get theirs all whilst your telling them the price is going up at a time of year when traditionally having your windows cleaned isn't at the forefront of people's priorities Personally I think you've left it too late but the flip side of that is for all we know, things could be even worse in April when alot of windys put their prices up. You could end up with prices on hold for a long time. It's a tricky one, there's rights and wrongs with both, go with your gut.
