What happens when your fixed rate ends?
What happens when your fixed rate ends, what it could do to your payment, and the timeline for securing your next deal.
Quick answer
When your fixed rate ends, your mortgage moves onto your lender’s standard variable rate, or a follow on rate set out in your offer, unless you arrange a new deal. That rate is usually well above today’s fixed deals, so your monthly payment can rise sharply.
You can usually secure a new rate up to six months before the end date. Once your fix has ended there is normally no early repayment charge, so you can switch at any time.

What happens when your fixed rate ends
Your fixed rate ends on the date in your mortgage offer. From the next day your lender charges a different rate, usually its standard variable rate, unless you have arranged a new deal. Some mortgages move to a follow on rate instead, often a tracker set out in your offer. Your monthly payment changes from your next payment date.
Most lenders write to you before your deal ends with the rate you will move to and the deals they can offer you. Your mortgage does not end, and nothing happens to your home: only the rate changes.
What it could cost
Standard variable rates are usually well above the best fixed deals. On a £200,000 repayment mortgage over 25 years, moving from 4.50% to a variable rate of 7.00% would raise the payment from about £1,112 to about £1,414 a month, an extra £302, or over £3,600 a year.

Your options
You can take a new deal with your current lender, known as a product transfer, move to a new lender, or stay on the variable rate. A product transfer is usually the quickest. Moving lender opens up the whole market but takes longer. Staying on the variable rate gives you flexibility, because there is normally no charge to leave, but it usually costs the most each month.

The timeline
| When | What many people do |
|---|---|
| 12 months before | Check the end date, any early repayment charge and your loan to value |
| 6 months before | Compare deals and secure one. Most lenders allow this without a charge |
| 3 months before | Product transfer offers are usually open by now |
| 1 month before | Confirm everything is in place for the start date |
| After it ends | If nothing is arranged, you are on the variable rate and can switch at any time |

If rates are rising or falling
If fixed rates are rising, securing a deal early protects you, because your offer usually holds for around six months. If they are falling, you can often switch to a lower rate before your new deal starts. Theo’s reading of which way rates are moving updates every weekday.
