Self Build

Providing individual mortgage advice; unique to you

Self build mortgages differ from regular mortgages by releasing money in stages as the build progresses, as opposed to paying out a lump sum in order to purchase the property.

They will offer the usual choices of fixed, variable, offset or discount mortgages and an option to remortgage your existing property might also be available. 

If you are going for an alternative build method or a green eco home then understandably lenders will be cautious. There are a few out there, including Ecology Building Society, who could be willing to take you on.

Staged Release of Funds

There are two formats for releasing stage payments:


Payments are made at the beginning of a stage. This improves cash flow and makes funds available for payments when you need them. They are usually a bit more expensive and charge an additional fee, as there is more risk for the lender. 


Payments are released after a stage is completed and a surveyor has made an interim valuation. This can cause cash flow problems and you may need to retain a cash buffer or set up some form of bridging loan to make payments when you need to. There will also be additional fees to pay for the stage inspections.

The Stages


Borrowing Limits

Income multiples are generally the same as regular mortgages but you should consult individual mortgage providers for details.

Most lenders offer loan to value ratios of around 75% but some offer up to 80%.

The usual income multiples apply and the amount you will be able to borrow is based on an assessment of your ability to pay it back and the size of deposit you’ll make.


Lenders will want to see the following:

  • Planning permission: At least outline permission for the land purchase and detailed for build costs.
  • Building regulation approval.
  • Plans and specification.
  • A full set of build costs.
  • Evidence of your registration with a warranty scheme.
  • Details of your builder and their qualifications.
  • Insurance documents.
  • Other supporting information.

As always, be sure to read and compare the small print carefully. Make sure you know exactly what you are being offered and what criteria actually trigger the release of stage payments. Check each policy's requirements, conditions and restrictions.

If you need a self build mortgage then get in touch, so we can research and compare for you what is out there before deciding which one will work best for you. 

Your home may be repossessed if you do not keep up repayments on your mortgage.
