Roger,
I haven't been cleaning windows for nearly half as long as you mate; but I don't like telling customers to their faces that their prices are going to increase.
I know, I know - I'm a big fanny. I prefer to use the following letter; and for some houses I almost doubled them. Roger, we work in the same part of the country and I have NO £5.00 houses.
See the letter, mate... (it looks a lot posher in Word format; with a proper header)

Dear Customer,
WINDOW CLEANING – PRICE INCREASE
We have increased our price for the monthly cleaning of your property from
£________ to £ ________. This increase will be effective at our next clean.
It is realised that this is a sharp increase in price, however when I first quoted for your property, I severely underestimated the price (You can just drop this line if it's not applicable). It is hoped that this will not deter you from being one of our valued customers and if you wish to discuss the above, please do not hesitate to phone me. You may (of course) also ask other window cleaners for a quote and I am sure you will find that we are still extremely competitive.
I would also like to remind you that:
We are fully covered by public liability insurance, up to two million pounds, for your safety.
We are as professional as possible. This is our full time occupation and we do not clean windows for extra 'beer/drug money'.
We are not 'fly by nights', who have started window cleaning, then three
months later – pack it all in.
This is the first time we have increased our prices in two years, and it will remain fixed for at least a year. As we have built our business, we have increased our prices for the new cleans we have taken on. This price increase will bring you in-line with which we are charging already and means that we will continue to clean your house, rather than abandoning you for more lucrative business.
We look forward to cleaning your windows in the future.
Ken and Helen
