Double glazing prices?

[The Gauge]

Anyone able to indicate if the quote I've had to replace our house front windows with double glazing is reasonable, as I have no knowledge of prices these days. I'm in South Yorkshire. Quote is from a well regarded local company that have been in business for years, I see them doing lots of installs and I've only ever heard good things about them, they are my preferred choice.

The quote is to replicate our existing windows with leaded glass, and coloured glass in the top lights

1 x Downstairs bay - two bottom & two top openers
1 x Upstairs bay - two bottom & two top openers
1 x Upstairs bay (small) - one bottom & one top opener

Scaffolding needed for the upstairs windows
(door not included)

£11k
