Mortgage Rates in 2026:
Why Now Is the Time to Improve, Not Move
The financial case for making the most of the home you already have
Posted 6 March 2026
If you've been thinking about moving to a bigger house for more space, the mortgage market in early 2026 is giving you a very good reason to pause and reconsider.
You're not alone in that feeling. Wanting more space but feeling priced out of the next rung. Worrying about locking into a higher mortgage when rates might fall — or might not. Sensing that moving should feel exciting, but right now it mostly feels risky.
Between stubborn interest rates, a stamp duty system that just got more expensive, and genuine uncertainty about where rates are heading next, the financial case for improving your current home rather than upsizing has never been stronger.
Let's look at the numbers — because this isn't about opinion or sales tactics. It's about what the figures actually say. We install verandas, yes — but the numbers speak for themselves. Even if you never buy from us, we want you to make a financially sound decision.
Where Mortgage Rates Stand Right Now
The Bank of England held its base rate at 3.75% in February 2026. While that's down from the 5.25% peak in late 2023, it's still significantly higher than the near-zero rates many homeowners locked in during 2020–2021.
Here's what typical mortgage deals look like in March 2026:
Best-buy deals sit lower — around 3.55% for a two-year fix if you have significant equity — but most homeowners looking to upsize won't be in that bracket. They'll be borrowing more on a higher loan-to-value ratio, which means higher rates. The real-world cost for most upsizers is closer to 4.2–4.6%, not the headline deals.
The uncertainty factor: In early March, the conflict in the Middle East pushed oil and gas prices higher, causing several major lenders including HSBC and Coventry Building Society to hike their fixed rates. Markets that had priced in two base rate cuts for 2026 are now expecting just one — and some economists predict rates could actually rise this year. The Bank of England's next decision is on 19 March.
What this means in practice: if you're considering upsizing, the mortgage you take on could be more expensive than you planned — and there's a real chance it gets more expensive still.
The Real Cost of Moving Up the Property Ladder
Let's say you currently own a home worth £300,000 with a £150,000 mortgage. You're thinking about moving to a £400,000 property for an extra bedroom or more garden space. Here's what that actually costs:
Your new mortgage
Selling at £300k, you clear your £150k mortgage and have £150k equity (minus selling costs). On the £400k house, you'd need a mortgage of around £270,000 after fees and costs.
| Scenario | Monthly Payment | Total Interest |
|---|---|---|
| Current mortgage (£150,000 at 4.24%, 25 years) | £812/mo | £93,530 |
| Upsized mortgage (£270,000 at 4.24%, 25 years) | £1,461/mo | £168,354 |
That's an extra £649 per month — £7,793 more per year. That's before we even get to the transaction costs.
Transaction costs of moving (spring 2026)
| Cost | Amount |
|---|---|
| Stamp Duty / LTT / LBTT on £400k purchase | £10,000–£13,350 |
| Estate agent fees (1.5% of £300k) | £4,500 |
| Solicitor fees (both sides) | £2,500–£4,000 |
| Surveys and searches | £1,000–£2,000 |
| Removal costs | £800–£2,000 |
| Mortgage arrangement & exit fees | £1,000–£2,000 |
| Minimum total to walk through the door | £19,800–£27,850 |
This is money you never see again. This is the cost just to stand in the new house — before you've even unpacked a single box.
A note on stamp duty: Since April 2025, the nil-rate threshold dropped back to £125,000 (from £250,000). On a £400,000 purchase, you're now paying £10,000 in stamp duty — that's £2,500 more than you would have paid under the old temporary rates.
Property tax across the UK
The tax you pay on a property purchase depends on where you're buying. England, Scotland and Wales each have their own system:
| Nation | Tax Name | Tax on £400k | Nil-Rate Threshold |
|---|---|---|---|
| England & N. Ireland | SDLT | £10,000 | £125,000 |
| Wales | LTT | £10,500 | £225,000 |
| Scotland | LBTT | £13,350 | £145,000 |
Wales has the most generous nil-rate threshold at £225,000, but its 6% rate above that means the bills end up similar to England. Scotland's 10% band above £325,000 makes it the most expensive nation for a £400,000 purchase. First-time buyers get relief in England (0% up to £300k) and Scotland (0% up to £175k), but Wales has no dedicated first-time buyer relief — all buyers pay the same standard rates.
What £20,000 Could Do to Your Current Home Instead
Instead of spending £20,000–£28,000 just on the costs of moving (before the increased mortgage payments even start), imagine putting that same money into the home you already love:
The framing is simple: moving = recurring cost + recurring stress. Improving = one-off cost + recurring benefit.
A well-designed veranda provides sheltered outdoor space you can use year-round for dining, entertaining, relaxing, or watching the world go by. While it doesn't add to your official internal square footage on a surveyor's report, estate agents consistently tell us that quality outdoor living spaces are one of the first things buyers look for — making your home more desirable and easier to sell at a strong price. With side options like sliding glass doors or aluminium walls, it can become a fully enclosed garden room.
Our verandas start from around £2,600 for a compact polycarbonate system (the entry-level Bolthole) and go up to £20,000+ for a large premium glass-roofed installation with all the extras (such as the Vista or Pavilion). That's a fraction of what moving costs — and you keep the home you already know and love. Get an instant price for any size or specification using our Online Quoter.
The Mortgage Maths That Nobody Talks About
Here's something most people don't think about when they're browsing Rightmove: the total cost of that bigger mortgage over its lifetime.
The extra £120,000 mortgage at 4.24% over 25 years
That's £120,000 borrowed plus £74,824 in interest — more than the average UK salary just in interest alone.
So the £100,000 "upgrade" to a bigger house actually costs you over £200,000 when you factor in the additional mortgage interest, property tax, agent fees, and moving costs.
Meanwhile, a £15,000 veranda with glass roof, integrated lighting, and heaters costs you £15,000. Full stop. No interest. No fees. No property tax.
What About Waiting for Rates to Fall?
This is the question on everyone's mind. The honest answer: nobody knows.
Just weeks ago, markets were expecting two base rate cuts in 2026 and mortgage rates were drifting lower. Then the situation in the Middle East escalated, oil prices jumped, and the outlook changed overnight. Some economists now predict rates could rise rather than fall.
The forecasting problem: End-of-2026 predictions currently range from 3.25% (optimistic) all the way to above 4% (pessimistic). On a £270,000 mortgage, that's the difference of roughly £130 per month. Waiting for "the right time" to move is essentially a gamble.
Waiting for the "perfect" mortgage rate is a bit like waiting for a sunny weekend in March — you could be standing there a very long time. Improving your home is the only way to guarantee a result you can actually enjoy this summer.
Improving your home doesn't require you to gamble on interest rate movements, refinance your mortgage, or lock yourself into 25 years of higher monthly payments. You pay once, you enjoy it immediately, and you add value to your property regardless of what rates do next.
Real-World Examples
Instead of moving from a three-bed to a four-bed (cost: £40,000+ in property tax, fees, and higher mortgage payments in year one alone), they added a 6m × 4m glass-roofed Haven veranda (~£11,250 for the structure) with sliding glass doors and heaters — around £18,000 all-in. They gained a year-round outdoor living room, kept their children in the same school, and significantly enhanced their home's desirability to future buyers.
With their mortgage nearly paid off, taking on a new £200,000+ mortgage for a bigger house with a nicer garden made no financial sense. A premium 8m × 4m Haven glass veranda (~£14,200 for the structure) transformed their existing patio into a space they use every day — morning coffee, reading, hosting grandchildren — without a single additional monthly payment.
They needed a separate space to work from home. Rather than moving to a house with a dedicated office (and the associated upsizing costs), they added a 6m × 3m Haven glass veranda (~£6,100 for the structure) with aluminium wall panels on one side, creating a light-filled, semi-enclosed workspace overlooking the garden. Total cost around £10,000 including the side options.
What Should You Do?
We're not going to pretend that a veranda is the answer for everyone. If you genuinely need to relocate for work, or your family has outgrown your home in ways that no outdoor space can solve, then moving might be the right call.
But if what you really want is more usable space, a better connection between your home and garden, or a reason to love your house again — then the numbers in 2026 overwhelmingly favour improving over moving.
Our suggestion: before you call an estate agent, explore what's possible with your existing home. Get a sense of what a veranda, garden room or carport would cost and what it would look like. Compare that honestly against the true cost of moving — not just the house price, but the property tax, the fees, the higher mortgage, and the disruption.
We're always happy to have an honest conversation about whether a veranda genuinely solves your needs. If it doesn't, we'll tell you. We'd rather you make the best decision for your family than push a sale.
Frequently Asked Questions
Should I move house in 2026?
It depends on your reasons. If you need to relocate for work or genuinely need more bedrooms, moving may be right. But if you primarily want more usable living space, the financial case in 2026 — with mortgage rates at 4–4.5%, higher stamp duty thresholds, and £20,000–£28,000 in transaction costs — strongly favours improving your current home. Our Improve Don't Move Calculator can help you compare the numbers for your specific situation.
Will mortgage rates fall in 2026?
The honest answer is that nobody knows. Markets were expecting two base rate cuts, but recent geopolitical events have pushed forecasts toward just one cut — or possibly none. End-of-year predictions range from 3.25% to above 4%. Making major financial decisions based on rate predictions is inherently risky.
How much does it cost to move house in the UK in 2026?
For a typical move from a £300,000 to a £400,000 property, transaction costs alone (stamp duty, agent fees, solicitors, surveys, removals) total £19,800–£27,850. That's before the increased monthly mortgage payments of roughly £649 extra per month. The full financial impact over the mortgage term can exceed £200,000.
Is a veranda cheaper than an extension?
Significantly. A professionally installed glass veranda typically costs £6,000–£20,000 depending on size and specification. A traditional brick extension of comparable area costs £24,000–£36,000, takes 3–6 months, and almost always requires planning permission. Our pricing guide covers costs in detail.
Will a veranda add value to my home?
Estate agents increasingly report that quality outdoor living spaces enhance buyer appeal and can contribute to higher valuations. While a veranda doesn't add to your official internal floor space, it provides functional living space that modern buyers actively seek. Our Property Value guide covers the evidence in detail.
