Porting Your Mortgage
Porting Your Mortgage: Taking Your Deal to a New Home
Moving home during a fixed rate? Porting lets you take your current mortgage deal with you and can help you avoid early repayment charges. But it is not automatic, and it is not always the cheapest option. Here is how it works.
★★★★★ Helping home movers across Scotland make the right call. Rated 5 stars by 235+ clients on Google.

Your home may be repossessed if you do not keep up repayments on your mortgage.
There may be a fee for mortgage advice. The actual amount you pay will depend upon your circumstances. The fee is up to 1% but a typical fee is 0.3% of the amount borrowed.

How It Works
You Move the Deal, Not Just the House
Porting means keeping your existing rate and moving it to your new property. Your lender still has to approve it.
- ✓Re-approval: your lender checks your income and credit again
- ✓Valuation: the new property is valued like a new purchase
- ✓Extra borrowing: any top up is usually on a different rate
- ✓Timing: buying and selling on the same day usually works best
How We Help

Five things to check before you move.
Check Your Deal
Is it portable? What are the early repayment charges and when do they end?
Work Out the Numbers
Compare porting against paying the charge and moving to a new deal.
Speak to Your Lender Early
Porting needs a new application, so leave time for it.

A bigger home may mean a top up loan with its own rate and term.
Line Up the Dates
Your sale and purchase usually need to happen together to port smoothly.

Porting Questions, Answered
The things home movers ask us most.
What does porting a mortgage mean?
Moving your existing mortgage deal to a new property instead of ending it.
Can I always port my mortgage?
No. Your deal must be portable and your lender has to approve the new application and property.
Can I borrow more when I port?
Usually yes, if you can afford it. The extra is normally on a separate rate.
Do I avoid early repayment charges by porting?
Usually yes on the part you port, but check the rules on timing and downsizing.
Is porting always the best option?
Not always. Sometimes paying the charge and switching to a better rate works out cheaper.
How long does porting take?
Similar to a new mortgage application, so allow a few weeks.
