We’re firmly committed to environmental sustainability. So we recycle all the old uPVC windows that we take out of customers’ properties. We’ve partnered with Eurocell Recycle to do this – the UK’s biggest recycling operator, which in 2021 stopped the equivalent of three million window frames from going straight to landfill. Specifically, it’s also one of Britain’s leading recyclers of uPVC windows. The company gives us recycling certification, and we don’t charge people a penny for this service.
