Need a new mortgage? Staying with your existing lender may now be cheaper than switching to a different one

If you need a new mortgage you might now be much better off sticking with your existing lender than switching to a new one. We look at the difference between 'sticking or twisting', and why the balance between the two has shifted.

When your mortgage deal expires and you're in need of a new one, you have two options: switching to a new deal with a different lender – known as remortgaging – or getting a new deal with your existing lender – known as a 'product transfer'.

For many years, finding the cheapest deal has usually been done by scouring the wider mortgage market and remortgaging with a new lender. Yet in recent months, with interest rates having climbed substantially, the gap between product transfer and remortgage deals has narrowed – and in many cases it's actually reversed. In addition to improved rates, product transfers also offer other advantages, such as ease of acceptance.

If you need to find a mortgage deal soon, see our Getting ready to remortgage guide for top tips.

The difference between a 'remortgage' and a 'product transfer'

The key differences between a remortgage and a product transfer are as follows:

  • With product transfers you stick with your current lender, but with remortgages you move elsewhere. For example, if you switch from Barclays to Nationwide, you'd be remortgaging. If you simply got a new deal with Barclays, you'd be getting a product transfer.
  • Fees are often lower with product transfers. You'll normally have to pay an arrangement fee, but that's often it. Legal fees are uncommon and you're unlikely to be charged a valuation fee (though this can be the case with remortgages too – so do check).

  • There's not normally an affordability assessment with product transfers, which makes the process quicker. So if you're not borrowing more money, this means you could be accepted for a new rate almost instantly. With remortgaging, as affordability assessments form a key part of the switching process, you might struggle to be accepted with a new lender, particularly if you're on the border of affordability, and the process will normally take longer.

Why you should consider sticking with your existing mortgage lender

If you're a homeowner with a mortgage deal that's expiring, there is increasing reason to consider switching to a new deal with your existing lender – though it's always best to check the deals you could get elsewhere before deciding.

That's because the difference in interest rates between product transfers and remortgages has narrowed considerably in recent months. In many cases, lenders now often offer a better rate to their existing customers than they do to new customers, as this table shows:

Mortgage rates for existing customers vs new customers (1)

If you're considering a product transfer but need to borrow more money on top of your existing mortgage amount, this is known as a 'further advance'. Interest rates on further advances can be worse than like-for-like product transfers, but this isn't always the case – again, it's worth comparing the rate your existing lender offers against what you could get on the wider market.

  4. If you've savings, use them to bag a cheaper deal. If you still owe more than 60% of your home's value on a mortgage, the more you can do to drop an LTV band, the cheaper your remortgage will be.
