Existing Santander mortgage customers moving home

If your client already has a Santander mortgage, there are a couple of options available to them when they're moving home.

We pay a procuration fee on the full loan amount, whether your clients are porting an existing product or choosing a new product. Some exclusions may apply.

Porting is when an existing Santander mortgage customer moves home and transfers their mortgage product for the rest of its term. Most of our products are portable.

  • Products can only be ported if it’s to buy a property. You can’t port a product to a property that's owned mortgage free or is being remortgaged.
  • Your clients and their property must meet our current lending policy, and we’ll do a full credit check.
  • If your client wants to borrow less than their current balance, we’ll charge an early repayment charge (ERC) on the amount they don’t port. So, if their current balance is £100,000 and the new mortgage will be £90,000, we’ll charge an ERC on the £10,000 difference. Your client's 10% overpayment allowance can't be used for this.
  • If your client’s borrowing more, top up borrowing can be taken from the new business range.
  • If the product they’re porting has less than 5 years remaining at the time of application, they don't qualify for our 5 year (or greater) fixed rate affordability.

If your client wants to borrow less than their current balance, we’ll charge an early repayment charge (ERC) on the amount they don’t port. So, if their current balance is £100,000 and the new mortgage will be £90,000, we’ll charge an ERC on the £10,000 difference. Your client's 10% overpayment allowance can't be used for this.

If your client’s borrowing more, top up borrowing can be taken from the new business range.

Please see our ERC waiver (choose a new product) tab if your client has 9 months or less left on their current deal at the time of application.

For more information, see our Existing Santander mortgage customers moving home guide.

If the purchase of the new property completes within 3 months (6 months for a new build property) of the redemption date of the existing mortgage, then your client can port the existing product to the new mortgage where they meet our key criteria. 

  • Your client must port the whole amount across to the new property to get a full ERC refund.
  • This doesn't include Flexible Offset mortgages which must redeem and complete on the same day (simultaneous).

Borrowing the same or more
On redemption of the existing mortgage, the ERC is paid in full. We'll automatically send your client any refund due within 4 weeks of completion of the new mortgage.

Borrowing less
On redemption of the existing mortgage, the ERC is paid in full. If the new mortgage is less than the existing mortgage, the ERC refund will be a proportionate amount. This means we’ll only refund an ERC on the amount they have ported. For example, if their current balance is £100,000 and the new mortgage will be £90,000, we’ll refund an ERC on the £90,000. For more information, see our Existing Santander mortgage customers moving home guide.

The Flexible Offset mortgage can be ported.

  • Redemption and completion must be on the same day (simultaneous). Your client must plan to sell the property they currently own as this can’t be retained. They won’t need to pay an ERC, however a benefit package ERC may apply e.g. £250 cashback or residential remortgage legal work.

If your client is porting and topping up, they must top up using their Flexible Offset product. 

If your client is porting and topping up, they must top up using their Flexible Offset product. Your dedicated contact can tell you about the process.

When porting a product, it's possible to make other changes, if the application and the property meet our current lending policy and affordability criteria.

Acceptable changes include: 

  • Amending the mortgage term, LTV or repayment method.
  • Porting an existing Help to Buy or Buy to Let product to a standard residential property.
  • Adding or removing a borrower (as long as one existing borrower remains).

Please note we’ll do a full credit check.

To port your client's mortgage, you'll need to know the:

  • existing loan amount,
  • product code, and
  • start date

To avoid delays, this information needs to be as accurate as possible. 

You and your registered administrator can get these details, including the ERC balance if needed through Live Chat or by calling your Broker Support Team. You’ll need to have your client’s permission and answer some security questions.

Alternatively, your client can get this information by calling us on 0800 917 5630. Lines are open 8am to 6pm Monday to Friday and 8am to 2pm Saturday. When they call, they'll be asked to provide their mortgage account number and confirm their identity. They can find their account number on their annual mortgage statement

Existing Santander and Alliance & Leicester mortgage customers moving home can choose a new business product for their total borrowing where your client has 9 months or less left on their current deal at time of application.

Where they’re currently tied in:

If there’s 9 months or less left on current deal at time of application If there’s more than 9 months left on current deal at time of application
  • If they’re borrowing the same amount or more, we’ll waive the ERC in full, or
  • If they’re borrowing less, we’ll charge an ERC on the amount they are not moving onto the new product, e.g. if their current balance is £100,000 and the new mortgage is £90,000, we’ll charge an ERC on the £10,000 difference. Your client's 10% overpayment allowance can't be used for this.
  • Any ERC must be paid in full.
Redemption and completion on the same day (simultaneous) Redemption and completion on different days (non-simultaneous)
  • You’ll need to ask your client to tell their solicitor to deduct the ERC from the balance on the redemption statement.
  • Your client must complete within 3 months (6 months for a new build property) to get an ERC refund.
  • On redemption of the existing mortgage, the ERC is paid in full. We'll automatically send your client any refund due within 4 weeks of completion of the new mortgage.

For further information on ERC waivers please view our residential lending criteria. All applications are subject to our current lending criteria.

If the maximum loan available on a new application is below what your client needs, our affordability calculator will display their current balance on the results tab.

We may be able to lend the current loan amount if:

  • No change of borrowers: the customers named on the new mortgage application are the same as those on the existing mortgage.
  • Interest only:
    • the interest only loan part isn’t increasing, or
    • the interest only loan part is increasing and meets our current interest only lending policy.
  • Existing mortgage hasn’t been redeemed: the existing mortgage hasn’t been redeemed at the time of application, but the property will be sold on or before completion.
  • Redemption and completion on different days (non-simultaneous): redemption of the existing mortgage must take place no more than 3 months before completion of the new purchase.
  • Property usage: the client is buying for owner occupation only.

Please note this list is not exhaustive. 

The application will be subject to a full review and affordability assessment by our underwriters before we can confirm if it can proceed.

Please speak to your dedicated contact before submitting your application.
