Mortgages explained.
Money understood.

The Budget lands on Wednesday 28 October. It's the first from Chancellor John Healey, and the speculation has already started doing what speculation always does: filling newspapers, spooking sellers, and giving everyone a vague sense of dread without telling them anything useful.

So here's the honest version. What's confirmed, what's still guesswork, and what any of it might do to the rate you pay.

What we actually know

Not much, which is the first thing worth saying out loud. A handful of measures have already been confirmed: VAT comes off domestic electricity bills from October, a £2 bus fare cap arrives in January, and business rates are being cut by 20% for pubs, clubs and live music venues.

Beyond that, the Prime Minister has said people may need to pay "a little more" in tax. Everything else you're reading is informed guesswork. Some of it from very well-informed people, but guesswork all the same.

The stamp duty rumour, and why it mattered anyway

For months the big story was that stamp duty might be scrapped and replaced with some form of land or property tax. Andy Burnham has now shut that down directly. Asked by Sky News whether it would happen in this Budget, he said: "That won't happen in the next Budget."

The frustrating part is that the rumour did damage regardless. When buyers think a tax on buying might vanish in ten weeks' time, some of them simply wait. Deals stall, chains wobble, and sellers drop asking prices to get attention. That isn't hypothetical. It's been visible in the market all summer.

It's a decent lesson in how this stuff actually works: the speculation often moves the market more than the policy does.

What's still floating around for property

Council tax reform keeps resurfacing, everything from percentage-based charges on higher-value homes to finally revaluing the bands, which are still based on what your house was worth in 1991. There's also longer-term talk of a land value tax, and the PM has said before that land is "under-taxed".

None of it has been published as an actual proposal. Treat it as weather, not forecast.

Interest rates: the bit most people have backwards

Most people assume the next move in rates is downwards. At the moment, the committee that decides isn't so sure.

The base rate has sat at 3.75% since the end of July. At that meeting the Monetary Policy Committee voted 6–3 to hold, and all three of the dissenters wanted rates to go up to 4%, not down, on the back of stubborn energy-driven inflation.

Most economists still expect 3.75% at Christmas. A few expect a rise before then. Cuts, if they come, are largely being discussed as a 2027 story rather than a 2026 one.

How a Budget reaches your mortgage

This is the bit nobody explains, and it's simple once someone does.

The Government borrows money by selling bonds, which in the UK are called gilts. If a Budget makes lenders nervous about how much the Government intends to borrow, they demand a higher return for lending it money, and gilt yields rise.

Gilt yields feed into swap rates, which are essentially what banks pay to lock in a fixed cost of money for a set number of years. And swap rates are what fixed mortgage rates get built on top of.

So the chain is: Budget → gilts → swaps → your fixed rate. It usually moves within days, and often before the Chancellor has even stood up, because markets price in what they expect to hear.

That's how a Budget can move your mortgage without the Chancellor mentioning mortgages once.

What the housing market's doing

Two numbers that look like they contradict each other, and don't.

Nationwide has the average house price at £275,465, up 1.6% on last year. Rightmove has average asking prices down 1.0% annually, and down £7,360 in a single month.

They're measuring different things. Nationwide tracks what buyers actually agreed to pay. Rightmove tracks what sellers hoped to get. With the number of homes on the market at a twelve-year high, sellers are pricing far more cautiously, while completed sale prices have stayed relatively stable.

Falling asking prices aren't the market telling you your home is worth less. They're the market telling you what it will bother turning up for.

So what should you do?

Nothing dramatic, and nothing based on a headline.

If your fixed rate ends within the next six months or so, it's worth having it looked at now rather than in November. Most lenders will let you secure a rate several months ahead and still switch if something better appears, which means you're covered either way, whatever 28 October brings.

If you're buying, don't try to time the Budget. Stamp duty isn't changing in it, and the transactions that go wrong tend to be the ones that hesitated rather than the ones that moved.

And if you're reading something stuffed with words like "gilt", "swap" or "fiscal headroom" and you can't tell whether it matters to you, just ask us. That's rather the point of the education side of what we do.

We'll do a proper plain-English breakdown of what's in it the week after the 28th.

Figures: Bank of England, Nationwide House Price Index (1 September 2026), Rightmove (17 August 2026), Moneyfacts. Everything above is general information rather than advice. Your situation is your own, and worth a proper conversation.

Between us, we've spent decades advising on mortgages, including years working with corporate clients who needed more than a generic lender questionnaire could give them. We kept running into the same thing: good clients getting squeezed into generic advice because their situation didn't fit the standard model. Freelancers, agency owners, people paid in dividends or day rates, portfolio landlords, even ultra-high-net-worth clients with more moving parts than a standard form allows for. They all needed someone willing to dig into their situation, not just run it through a calculator.

That's what The Mortgage Collab is for. We're independent, we're fully regulated as an appointed representative of Altura Mortgage Finance Limited, and we work through the Paradigm Mortgage Club for access to some of the leading rates in the market. It's built to be collaborative rather than transactional. Hence the name.

We'll be using this space for genuine updates: rate changes worth knowing about, things we're seeing in the market, and the odd bit of plain-English explanation for whatever's confusing people that month. Get in touch if there's something specific you'd like us to cover.
