@GrandOldTeam we paid just over £11,000 two years ago for ours to be replaced for a fairly large semi-detached house: all new PVC acoustic double-glazed.*
Some companies wanted closer to £15K, so you will get some variation, so I would get multiple quotes and read up on their reviews before choosing.
I looked a triple glazing, and if your priority is acoustics then double with the right glass is better. If you have under floor heating in some rooms, it's a solid option.
You can actually get a mixture across the house, so maybe have a look at that depending on your circumstances. In Liverpool, Allerton Glass are a good option.
