Mortgage lenders are increasingly offering green buy-to-let deals to reward landlords with energy-efficient properties, as the UK government moves to phase out less energy-efficient homes as part of its commitment to become more environmentally friendly.
In this article, we explain what green buy-to-let mortgages are and what a property needs to be eligible for one, as well as our list of the best deals on the UK market for landlords.
What is a green buy-to-let mortgage?
A green buy-to-let mortgage offers buyers intending to rent out a property favourable terms for choosing one that is more energy-efficient, or making improvements to the property which make it more environmentally friendly. Usually this involves lower interest rates or cashback. They are typically available for new-build properties as these are more likely to be built to modern energy efficiency standards, but green buy-to-let mortgages can also apply to older properties that have been renovated to meet current requirements.
What are the requirements for a green buy-to-let mortgage?
Individual lenders have different requirements for how energy-efficient a property needs to be in order to qualify for a green buy-to-let mortgage. Usually this decision is based on the property’s Energy Performance Certificate (EPC) rating - which is required for any home being built, let, or sold - and should be arranged by the seller or landlord.
An EPC puts a property on a scale from A to G - A being the most energy-efficient - and helps to form a general idea of the estimated energy costs of the property. It can also indicate the potential cost of implementing changes to make the property more energy-efficient. For example, if the property currently has an EPC rating of E, it will probably be quite an expensive task to make renovations to lift it up to an A.
New-build homes tend to have higher EPC ratings, while older properties typically have lower ratings, often around D or E. The average EPC rating for a home in the UK is D.
Most lenders will require that the property achieves an EPC rating of between A to C in order to be eligible for a green buy-to-let mortgage. You will need an accredited assessor to give your property an EPC rating. You can search for an assessor near you using the following links:
Should you get a green buy-to-let mortgage?
Although landlords are not currently legally required to get a green buy-to-let mortgage, the UK government’s Department for Business, Energy and Industrial Strategy is currently consulting on plans to increase the EPC requirement to a C rating for all tenancies by 2028.
If you are letting properties, or you are intending to, you should consider that green mortgages are most likely here to stay and may even become the norm in the future. You may want to consider ways to make energy-efficient improvements to your rental properties, not just so you are eligible for more favourable mortgage rates, but also to protect your properties’ market appeal going forward.
