Additional borrowing

We offer additional loans up to 90% LTV (up to 85% LTV for debt consolidation* and part and part mortgages). However, additional loans can’t be done via a broker and clients must apply directly online or by phone.

*Debt consolidation can only be considered for informal loans, defined as monies lent from a person(s) where the loan has no repayment schedule e.g. loans from a parent to a child for the purchase of their first home.

All additional loan applications are subject to a full affordability assessment and proof of income.

We can offer additional loans on an advised or non-advised basis.

Please note we don’t offer additional loans if the client has a Buy to Let or consent to let mortgage.

If your client doesn't want advice and they have access to Santander Online Banking, they can get an instant decision in principle and apply for an additional loan online.

Your client can register for Santander Online Banking on our Santander website.

If your client wishes to take out an additional loan but they don't want to apply online, they can call us on 0800 092 3881.

Opening hours are Monday to Friday 9am to 6pm and Saturday 9am to 2pm.

Flexible Offset mortgages

For existing Flexible Offset mortgage clients, we agreed a credit limit when the mortgage was set up.

If your client has available funds on their Flexible Offset mortgage, they'll be able to drawdown these funds up to their agreed limit. 

If your client wants to increase their credit limit, they may be able to do so. The maximum LTV is 75%, subject to lending criteria. They'll need to phone 0800 092 3881.

Interest only mortgages and additional loans

We can consider additional borrowing for existing clients that have an interest only loan part on their current mortgage where:

  • the total lending doesn't exceed 85% LTV
  • the interest only part of the loan doesn't exceed 50% LTV
  • sale of property is the repayment vehicle. A £300,000 buffer is needed.

The whole loan is subject to standard new business lending criteria.
