Newbury Building Society has expanded its GoGreen Mortgage range with the launch of two products for its existing buy-to-let (BTL) mortgage customers. 

The products, which have been launched for both individual borrowers and limited companies, are to help existing customers who wish to secure further lending to improve the energy efficiency of their rental properties. 

The mortgages are available for loans of between £2,500 and £39,999, with the requirement that at least 50% of the funds will be used for environmentally-friendly improvements to the property.

The improvements can include cavity wall insulation, solar panel installation, or the fitting of an air source heat pump. 

The society said there are no arrangement or booking fees, while overpayments are permitted on both products. 

Newbury Building Society lending manager Roger Knight comments: “We are keen to help our borrowers improve the energy efficiency of their let properties. Government legislation is in the pipeline that will force landlords to ensure their properties meet minimum energy standards and we are here to help ease this transition.”
