Additional borrowing – it’s a bit like your mortgage

Additional borrowing is not like a personal loan – it's secured on your property, just like your mortgage. You can spread payments out over your mortgage term, but just like your mortgage, if you can't keep up with the additional payments you risk losing your home. You should always check to see if you can get a better deal before applying.

For starters

Make sure you check these first:

  • The minimum borrowing amount is £5,000.
  • You must have had your West Brom mortgage for more than 3 months.
  • You can’t use additional borrowing to pay off any unsecured debts, such as credit cards and personal loans. It really is for your home.
  • You will have to pay a £99 additional borrowing fee.
  • You must still meet our lending criteria.

*Initial estimated monthly payments are calculated based on the figures entered above on a capital and interest repayment basis.
**For owner occupier mortgages, the actual variable rate applied will be based on the value of your property relative to the outstanding mortgage balance (this is known as the Loan to Value (LTV)). However, this rate will never be higher than the Society’s Standard Variable Rate at that time. For further details about what happens to your interest rate when your mortgage offer period ends, click here.

We’ll instruct a mortgage valuation. This is for our own use only. The cost of the valuation is set out in the product features. Where you feel you need more information about the property including its condition, there are three additional types of survey available to you: Home Survey Level 1 (Previously known as a Condition Report), Level 2 (Previously known as a Home Buyers’ Survey) and Level 3 (Previously known as a Building Survey). You’ll need to decide which level is best for you. For further details please visit rics.org

Representative example

A mortgage of £139,000 payable over 25 years initially on a fixed rate for two years at 3.99% and then on our current standard variable rate of 6.39% (variable) for the remaining 23 years would require an initial payment of £1,203.97, 26 monthly payments of £732.93 and 273 monthly payments of £913.76.

The total amount payable would be £269,868.91 made up of the loan amount plus interest (£130,743.91) and an account management fee (£125 - paid upon redemption).

The overall cost for comparison is 6.1% APRC representative.

This representative example assumes mortgage payments are made on the 1st day of a calendar month.
