Russell Galley, managing director at Halifax, said: “While upgrading our homes is simply a labour of love for many of us, others invest in renovation to increase value and maximise selling potential.

“Loft conversions and green features can generate attractive potential returns, yet traditional factors including location, local property price, access to schools and transport will continue to have a big influence on house prices. That’s why it’s important to do your research if you’re looking to sell as, you can get a better sense of the most attractive improvements by understanding your local markets.”
