Windows Plus were better by miles!

I spoke to Anglian Windows, Everest and Windows Plus UK (last!) and I am very pleased I took the advice I read online to go with a local company. I don’t have enough time to describe the whole process (which took several months), but long story short – Windows Plus were better by miles! The sales process was honest, informed and short (Everest’s salesperson was in my house for 4 hours!). I told Adrian what I was looking to achieve and he nailed it within 20 mins. The windows were ready to install a week later. The quality is great and the fitters were polite, tidy and quick. Not only this, but Windows Plus was literally half the price of Anglian and Everest. I’ll be asking Windows Plus back in due course for some follow up work. Thanks!
