We are a building society that specialises in mortgages for buy-to-let projects which meet specific energy ratings - whether you are looking for a self-build property to buy-to-let or improving the energy performance of an existing property to buy-to-let, see our buy-to-let mortgage in the UK.
- Our current buy-to-let Variable Rate is 4.90%
- To assess affordability the rental income derived from the property must be at least 35% more than the mortgage repayment due. We also need to evidence you have sufficient personal income to maintain your personal expenditure
- Energy efficient homes are rewarded with discounts, which are called C-Change sustainable homes, C-Change retrofit and C-Change energy improvements, off our Variable Rate – see how C-Change discounts work, below
- You can borrow up to 80% of the property’s value or purchase price (whichever is the lower) on a repayment or interest only basis
- An early repayment charge may be payable if you repay all or part of your mortgage within the first two years
- A non-refundable mortgage application fee of £350 is payable in addition to a mortgage valuation fee
- A maximum mortgage term of 25 years is available, subject to eligibility
- Mortgages are available on a repayment or interest-only basis, subject to eligibility
- Applicants can only have three buy-to-let mortgages, this includes the buy-to-let mortgage they are applying for with Ecology
- Buy-to-lets which need a renovation mortgage need to improve the Energy Performance Certificate by at least two grades
- Our mortgages for buy-to-let are not regulated by the Financial Conduct Authority.
What we lend on
We are experts in providing buy-to-let mortgages for self-build, renovation, conversion projects and where you are extensively improving the energy performance of a property. We don't have a 'tick box' approach to assessing projects –in many instances, we'll welcome projects that standard lenders may not accept. We will consider:
- Energy efficient self-build projects
- Renovations to existing residential properties that improve the energy efficiency
- Barn conversion projects
Our mortgages are available in the UK (England, Scotland, Wales and Northern Ireland).
Our approach to lending for buy-to-let mortgages
- We release stage payments during the project as and when the value of your property increases during the works
- Our buy-to-let Variable Rate applies during the works and our discounts are applied from the date we receive evidence that the works are completed and, if applicable, the Energy Standard rating required has been achieved.
Our standard of service
Where a mortgage is not regulated by the FCA (as shown on the 'Key features' tab), you will be provided with full information about the mortgage products available from the Society so that you can make an informed decision as to which is suitable for your requirements.
Jenny’s story: A simple and light urban Passivhaus

She also wanted to create a low-energy and low-tech build, constructed from sustainable, locally sourced materials. With the support of an Ecology mortgage, Jenny achieved this ...ReadSee all projects

Irene and David’s story: Converting to Passivhaus
Project type: Conversion
After living happily in a Victorian house on the outskirts of Ripon, North Yorkshire, for 20 years, Irene and David were ready for a change. They wanted a home that was less costly to heat and maintain, in a location that would reduce their reliance on car travel. This is exactly what they achieved. Their new house is an energy-efficient converted ...ReadSee all projects
Ecology Building Society was rated as an ethical Best Buy for our mortgages, ISAs and savings accounts by Ethical Consumer magazine in its product guide rankings (May/June 2018 issue).
As a building society with a unique mission to build a greener society, we lend on projects and properties that support our aims through their reduced impact on our environment. Making your home energy efficient is a major way you can support tackling climate change – while saving on your energy bills.
We reward borrowers whose properties are energy efficient (therefore have lower carbon emissions) with our C-Change discounts off our Standard Variable Rate which helps them save money on their mortgage. We call our discounts ‘C-Change discounts’ simply because we’re aiming to make a ‘sea-change’ of difference to our climate with each property or project we fund.
The level of our C-Change sustainable homes or C-Change retrofit discount that applies is based on the Energy Standard rating achieved on the self-build, renovation or conversion when the work is completed. Our C-Change energy improvements discount is based on the qualifying energy measures being installed. The discount is applied from the date we receive evidence that the work has been completed and if applicable the Energy Standard rating required has been achieved.
For us to apply the C-Change sustainable homes or C-Change retrofit, once your work is complete you need to provide an Energy Standard certificate and, if applicable an Architect or Building Control certificate. Or, for us to apply the C-Change energy improvement discount, please send us all invoices for qualifying works.
The discounts are only applied to our Variable Rate from the date we receive evidence that the work has been completed and, if applicable, the Energy Standard rating required has been achieved.
