My house is identical to my neighbour's who had windows supplied and fitted before April 2002. The same supplier fitted the same windows to our house, incorporating the April 2002 changes in glass legislation, but said that they would have to charge me 20% above my neighbour's price because of the higher costs they incur following the new April 2002 legislation.

My neighbours glass is flat. The glass in my house has roller marks. I have rejected the windows and now have laminated glass because they could not supply toughened float glass without the roller marks. It has taken 4 months and a week off work for myself to reach this point. Do you think the supplier is justified in charging the extra 20%? The laminated glass is 'smooth' looking but is a different colour to the float glass windows. I am aware of the benefits of laminated glass. My primary reason for having double glazing was to improve the appearance of my house for selling. I'm now starting to find other defects like a draft blowing under the front door frame, and bubbles bursting through where seallant has been used with cold air flowing through from the outside.

Allowing a little for inflation and the higher spec now required since April
2002 its possible you would be paying 20% more than your neighbour. We have
known of some suppliers claiming they have had to increase their prices by
as much as 25% - but would say that 10 - 20% is an average increase.

By the way Laminated glass is generally more expensive than toughened glass. Not sure I understand what you mean by "roller marks" on toughened glass? Can't see why your supplier could not supply you with toughened glass of an acceptable standard.
