Self Build mortgages

Specialist mortgages for people dreaming of buying a plot of land and building their own home – now including a range of incentivised Green Self Build products.
We are proud to have been awarded ‘Best Self Build Lender’ in the 2024 Build It Awards. A self build mortgage is designed to fund a range of home building plans, including self and custom build. It’s different to a traditional mortgage as funds are released in stages.
Green Self Build Mortgages
We are committed to making sustainable home ownership more accessible and affordable for all. We’ve taken our award winning Self Build products to create a range of green solutions to reward self builders who focus on energy efficiency, carbon reduction and long term cost savings. Green product incentives include cashback – payable at the first stage advance to assist with the cost and installation of green features – and no product fees.
Additional features of the green mortgage products include enhanced affordability criteria. This recognises the savings customers who achieve high EPC on their build will make on their energy bills each month, potentially increasing the amount they are able to borrow as well as improving the energy efficiency of their homes.
