What are energy-efficient windows and doors?
They’re modern uPVC or composite products designed to reduce heat transfer, enhance security, and comply with the latest building regulations. Double or triple glazed, they form a critical part of your home’s energy envelope.

Why upgrade your windows and doors?
Replacing old windows and doors can dramatically improve your home’s thermal performance and comfort.
Old windows leak heat and let in draughts.
Secure doors reduce the risk of break-ins.
Upgrades can increase property resale value.
Ageing frames and seals no longer close, lock or seal properly.
Modern glazing cuts condensation and noise.
Key Benefits

Northern Retrofit put in high-quality cavity wall insulation for me as a private customer. Their survey was very thorough and the quote was very competitive. The install went perfectly, even though there was some tricky areas on my house, and the team answered all my questions.
