Rate context and outlook
The Bank of England held Bank Rate at 3.75% on 17 September 2026, its sixth consecutive hold, but three of nine MPC members voted to raise it to 4.0%. The Committee warned policy may have to tighten if the Middle East conflict persists.
Fixed rates are priced from swap rates, and the 2-year swap rose from 4.26% on 3 September to above 4.70% by mid-month, so most major lenders repriced fixed rates upward two or three times in September. The next decision is on 5 November. If your deal ends in the next six months, securing a rate now and reviewing it before completion is the lower-risk approach.

Frequently asked questions
Is let to buy harder to get?
Lenders check both affordability tests together, so it takes longer.
Do I pay the SDLT surcharge?
On the new home, yes, if you keep the old one — unless it is a replacement main residence situation; take advice.
Can I release equity from my current home for the new deposit?
Yes — the BTL remortgage can raise the deposit, subject to rental cover.
What rental cover do lenders use?
Commonly 125% for basic-rate taxpayers and 145% for higher-rate taxpayers, at a stress rate.
Is let to buy a regulated mortgage?
The residential purchase is; most BTL remortgages are not.
How much can I borrow?
Usually 4 to 4.5 times income, with some lenders going to 5 or 5.5 times for higher earners and certain professions, subject to affordability.
How long does a mortgage take?
A mortgage in principle takes minutes to a day; a full offer usually takes 2–4 weeks from application.
Is a lower rate with a high fee better than a no-fee deal?
It depends on the loan size. On smaller loans the no-fee deal often wins; we compare the total cost over the fixed period.
How early can I remortgage?
You can secure a new deal up to six months before your current one ends.
What documents will I need?
ID, proof of address, 3 months' payslips and bank statements, or 2 years' accounts or tax calculations if self-employed.
