What we lend on

We are experts in providing mortgages for unique renovation projects and 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:

  • Thatched properties
  • Historic or listed buildings
  • Fire damaged buildings
  • Non-standard construction types, such as timber framed
  • Buildings in a poor state of repair.

Our mortgages are available in the UK (England, Scotland, Wales and Northern Ireland).

Our approach to lending during your renovation project
  • We release additional funds when valuations show your property has increased in value
  • Our Standard Variable Rate applies during the renovation works and our discounts are applied from the date we receive evidence that the renovation work has been completed and the energy rating required has been achieved.
Our standard of service

The Financial Conduct Authority (FCA) has laid down detailed rules about the service we must offer on regulated residential mortgages. Under these rules, we will provide you with advice and a recommendation on which of the Society's products is most suitable for you, based on your needs, preferences and affordability.

C-Change discounts explained

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.

When your renovation is complete

Our Standard Variable Rate applies until we receive evidence that the Energy Standard rating required has been achieved and, if applicable, work has been completed. Once your renovation is complete, you need to provide a copy of the final Energy Performance Certificate (EPC).
A discount between 0.25% and 1.50% will apply to our Standard Variable Rate for every grade improvement in your home’s EPC rating and the discount will be applied to all your mortgage balance.

How we work out your Variable Mortgage Rate:
Standard Variable Rate (SVR) minus C-Change retrofit discount = Variable Mortgage Rate
For homes needing extensive renovations / energy efficiency improvements: C-Change retrofit discount

The C-Change retrofit scheme offers a discount of 0.25% from our Standard Variable Rate for each rating improvement in your home’s Energy Performance Certificate (EPC). This could be either its Energy Efficiency or Environmental Impact rating – whichever is the highest.

For example, if either EPC rating improves from E to C after the works to the property are completed, a discount of 0.50% will be available on the whole of the mortgage, for the duration of the loan. The discounts are deducted from our Standard Variable Rate (currently 4.15% – the overall cost for comparison is 4.30% APRC).

To apply the discount, we need to receive an EPC before you undertake works to your home and another EPC once works are completed. We will compare the revised EPC with the original rating, and apply the discount based on the grade improvement achieved. Until we have received your revised EPC, we will charge interest at our Standard Variable Rate. You can find out more by downloading Our C-Change discount leaflet.

Renovation FAQs

Do I need to provide planning permission for my renovation?

Planning permission is required from your Local Authority if you are extending or altering the property and this requires formal planning permission.

What information do I need to progress my renovation mortgage application?

You’ll need to have a specific property renovation in mind and provide details of material and labour costs, the current Energy Performance Certificate (EPC) of the property and the projected EPC rating when you complete your renovation.

What deposit do I need for my renovation?

You need a 10% minimum deposit to purchase the property and a further 15% – 20% of total build costs to start your renovation.

Do I still need a deposit for my renovation if I already own the property?

No, you don’t always need a deposit; we can lend based on the value of your property to start the renovation, providing you already own the property and it’s mortgage-free. Also, we can help you repay any outstanding finance on the property if you need it.

Do borrowers who are planning to renovate need to show how they plan to improve the property’s energy efficiency?

Any project we support needs to show details of the proposed renovation with an indication of the Energy Standards you are renovating to, and how the renovation costs are expected to be funded with savings and mortgage finance. We don’t just lend on the property purchase.

How long do I have to complete the renovation?

We allow a maximum of 2 years for you to complete the renovation, although we encourage you to complete earlier to benefit from our C-Change retrofit discount which is applied to our Standard Variable Rate from the date we receive evidence that both the work has been completed and the Energy Standard rating required has been achieved.

Do you offer stage payments for a renovation?

Yes, we release funds as and when the renovation progresses and release up to a percentage of the increased value of the property.

Can I have interest-only mortgage during the renovation phase?

We offer an interest-only mortgage only when you have a qualifying repayment vehicle to support this for example an established ISA, endowment policies or Pension Plan.

Does the renovation property have to be my main residence?

Yes, although we do offer a buy-to-let mortgage. Please bear in mind that we don’t offer mortgages for second homes, holiday homes or homes classed as mobile planning.
