Your 6-month window to insure against mortgage rate rises

If your mortgage's initial rate ends within the next six months, contact your mortgage adviser today. Mortgage offers can last up to six months. Securing one now locks in today's rate as insurance against upward movements.

Iran and US forces exchanged missile and drone strikes in the Gulf again on 13 July. Oil prices climbed. Markets had expected Bank of England rate cuts this year. They now price in possible rate hikes.

Or, if you're a political sceptic. Andy Burnham is unknown and brings uncertainty over his plans or competence.

Gilt yields have surged in response. The 10-year gilt hit 5.13% earlier this year — its highest since 2008 — and remains elevated.

SONIA swap rates set the benchmark for fixed mortgage pricing. The latest figures show the pressure clearly:

• 2-year SONIA swap: 4.18% (4.04% a month ago, 3.49% a year ago)
• 5-year SONIA swap: 4.31% (4.14% a month ago, 3.75% a year ago)

Lenders reprice within days when swaps move. Several have already withdrawn products or raised rates this year.

The practical move is straightforward. Most lenders let you secure a new deal up to six months before your current one ends. The offer stays valid while your existing rate runs. If rates fall before completion, you can often reapply. If rates rise, you are protected. No early repayment charge applies.

About 1.8 million UK mortgage holders face renewal in 2026. That pool is large, and lender capacity at the sharpest rates is not infinite.

Do not wait until your deal ends and you slip onto your lender's standard variable rate. SVRs typically sit two to three percentage points above the cheapest fixed deals.
