The Bank held. Your clients' mortgage rates didn't.

The Bank of England held Bank Rate at 3.75% on Thursday. Anyone who has priced a two-year fix lately could be forgiven for asking what, exactly, was being held.

Bank Rate has not moved since March. The average two-year fixed rate has. Moneyfacts puts it at 5.73% on 15th September, up from 4.84% on 1st March, an increase it calculates at £131 a month on a £250,000 mortgage over 25 years. The Bank's own September minutes put the quoted two-year fixed rate around 95 basis points higher than before the conflict in West Asia began.

So the Monetary Policy Committee held, and the mortgage market tightened anyway. That is how fixed rate pricing works, and it has an awkward implication for how brokers talk to clients over the next six weeks. The decision that matters for most of them is not the one the MPC makes on 5th November. It is the one they make, or fail to make, about securing a rate before then.

The market has already voted

A two-year fix is priced off what lenders expect it to cost to fund and hedge a two-year loan. That means the expected path of Bank Rate over two years, expressed through swap rates, plus the lender's margin, funding mix and appetite for volume.

This month the expectation moved decisively. ONS figures published on 16 September showed CPI inflation rising to 3.1% in August, from 2.9% in July. The MPC's minutes note that Brent crude and UK wholesale gas had risen by 36% and 78% respectively since the run-up to the July Monetary Policy Report, and that inflation could reach slightly above 4% in the first quarter of 2027. Three members, Megan Greene, Catherine Mann and Huw Pill, voted to raise rates to 4%.

Markets took the hint before the committee did. As Financial Reporter reported when the Bank held in a 6-3 vote, pricing already assumed a rise to 4% later this year and two more in 2027. Moneyfacts says swap rates have climbed above 4.70%, and the big lenders duly moved. NatWest, Santander, HSBC, Lloyds and TSB repriced for the second time this month in what our coverage called a second wave of hikes ahead of the rate decision.

Treating the MPC announcement as the moment mortgage prices change is a bit like checking the weather forecast to find out whether it rained yesterday. By the time the Committee votes for a rise, if it does, much of that rise will already be sitting in product rates. A client who says they will "wait and see what the Bank does" is waiting for news that has, in pricing terms, largely been published.

Huw Pill made a version of this point about monetary policy itself earlier this month, arguing that "if you follow a 'wait-and-see' approach and then do not 'see', all you have done is waited." He was talking about the MPC. The line travels rather well.

The pain hasn't reached the statistics yet

There is a lag between this repricing and the data most of us watch, and it matters for how we read the market. The Bank's Money and Credit release for July, published on 1st September, put the effective interest rate on newly drawn mortgages at 4.45%, up from 4.35% in June. That is well below the advertised averages above for two reasons. It measures loans that completed in July, many on offers secured weeks or months earlier. And it is weighted by what borrowers actually took, which tilts towards cheaper, lower-LTV deals. The gap between the two is, in effect, repricing still working its way through.

Activity data tell a similar story in early form. Net approvals for house purchase fell to 56,100 in July from 58,200 in June, while remortgage approvals edged up to 34,500 from 34,100. Approvals are not completions, and one month is not a trend. But the direction fits a market in which purchase demand is softening while refinancing carries on because it has to.

Refinancing is where the timing question is sharpest. FCA Mortgage Charter data, covered in our report on borrowers locking in a new deal up to six months ahead of maturity, show 880,635 did so in the first half of 2026. That suggests early rate-securing has become normal behaviour rather than a specialist tactic. Moneyfacts, meanwhile, estimates that around 750,000 households whose deals expire this year are currently paying less than 3%. Those borrowers were always heading for a payment shock. The question now is how big.

The case for waiting, taken seriously

The strongest counterargument is that the market may be wrong. Core CPI was unchanged at 2.6% in August and services inflation steady at 3.4%, and the MPC majority noted "little evidence so far" of material second-round effects on wages and prices. This is an energy shock with a geopolitical cause. If the conflict eases and oil falls back, swap rates could retreat quickly, and a client who fixed at 5.7% in September might watch cheaper deals appear by Christmas.

Fair enough, and nobody should pretend to know which way this breaks. But it argues for a particular kind of advice, not for inaction. Some lenders let an existing borrower secure a product transfer early, or let a remortgage applicant switch to a cheaper product before completion. Where that's allowed, the early rate works less like a bet and more like an option: protection if rates keep rising, with room to re-select if they fall. The terms vary by lender, and fees, offer validity and re-application requirements all need checking case by case. Where that flexibility exists, though, the asymmetry favours acting. Where it doesn't, the conversation is a genuine judgement about risk and deserves to be recorded as one.

Buyers are a different case. A House Buyer Bureau survey reported by Financial Reporter found almost half of homebuyers were delaying, or considering delaying, until after the Autumn Budget, with mortgage rates the most commonly cited worry. The Budget is due on 28th October, a week before the next MPC decision. Wanting to know about stamp duty first is reasonable. But a buyer who waits to see the Budget and then the Bank Rate outcome is choosing to shop in November at whatever rates the market has settled on by then. That may turn out fine. It should be a deliberate choice, made with the rate risk understood, rather than an accident of calendar-watching.

There is an affordability angle too. Lenders assess affordability at the rate offered, often against a stressed rate as well. So if rates rise between agreement in principle and full application, the maximum loan can shrink. For first-time buyers stretching at higher loan-to-values, that can decide whether a case works at all.

What matters over the next fortnight

With no MPC decision before 5th November and no Budget until 28th October, the coming fortnight is less about events than housekeeping, which is where brokers can do the most good.

The practical priority is to go through the client bank for anyone whose fix ends before the middle of next spring and who has not yet secured a rate, particularly those coming off deals below 3%. For them, the useful question is not what the Bank will do in November. It is whether they can secure something now that protects them if pricing keeps rising, while leaving room to switch if it falls. For buyers, the job is to make sure any decision to wait is made with the numbers in front of them. That includes what a further 0.25 percentage points would do to their payments and their borrowing capacity.

The Bank held on Thursday. The mortgage market, for now, has not. Brokers' advice should follow the market that clients will actually borrow in.
