New research from Paragon Bank reveals that over half (57%) of landlords who have improved the energy efficiency of their properties have not commissioned a new EPC assessment afterward—potentially missing out on access to lower green mortgage rates.

Paragon’s survey of 500+ landlords shows that only 28% had properties reassessed post-upgrade, with most seeing improvements to their EPC rating. However, with 60% of landlords still owning a property rated EPC D and a quarter with even lower ratings (E, F or G), nearly half of the average landlord’s portfolio fails to meet the proposed minimum EPC C standard.

Louisa Sedgwick, managing director of mortgages at Paragon, urges landlords to reassess upgraded properties to take advantage of preferential green mortgage rates for EPC A-C homes. She also voiced concerns that the Government’s proposed 2030 EPC C target for all rented homes is unrealistic and may worsen the rental housing shortage. Paragon is calling for a phased approach to implementation between 2030 and 2035.
