If you’re weighing up whether to buy a new home or renovate your current one in 2026, the numbers have shifted noticeably. A typical UK home move now costs between £25,000 and £55,000 all in, with stamp duty as the single biggest chunk. Meanwhile, a meaningful renovation runs from £20,000 to £100,000 depending on scope, and typically recovers 50 to 90 percent of its cost in added property value. I’ve been watching this trade-off for years, and what I keep seeing is that the old rule of thumb — “just move, it’s simpler” — no longer holds the way it used to. The question has become more nuanced, and the answer depends on a handful of forces that are pulling in different directions right now.
Here’s what you actually need to know. The decision isn’t just about which option costs less upfront. It’s about timing, trade availability, and what the next few years look like for both mortgage rates and build costs. I’ve seen too many people make a choice based on one number — the monthly payment or the estate agent’s valuation — without factoring in the hidden costs on both sides. This article walks through the real trade-offs so you can make a call that holds up.
The core trade-off: moving versus renovating in 2026
The first thing to understand is that neither option is cheap, but they cost you in very different ways. Moving hits you with a lump of transaction costs upfront — stamp duty, estate agent fees, conveyancing, surveys, removals. Renovation spreads the cost over months and gives you back equity, but it comes with disruption and the risk of cost overruns. The key term here is stamp duty land tax — the single biggest cost in any move.
What I tend to notice is that people underestimate the total cost of moving by a wide margin. They see the estate agent’s fee and the stamp duty calculator, but forget the conveyancer, the survey, the EPC, the mortgage arrangement fee, and the removals van. Add it all up and you’re often looking at £30,000 or more before you’ve spent a penny on the new place. That’s money that could have gone into a new kitchen, a loft conversion, or an extension in your current home. If you’re in a property you mostly like, the maths often leans toward renovating — especially when you factor in what you’d lose on the sale.
Why the timing matters more than ever
Four forces are pulling the decision in different directions right now, and understanding them is the difference between a good call and an expensive regret. Mortgage and finance costs are pulling toward waiting — the Bank of England held Bank Rate at 3.75% in April 2026, and the path to lower rates looks slower than many hoped. But build costs are pulling hard in the opposite direction. The BCIS forecasts tender prices up 15% by 2031, with annual inflation already running at 2.8% in Q1 2026. On top of that, 81% of tradespeople plan price hikes averaging 9.5% this year alone, according to the Checkatrade Trade Index 2026.
Let me give you a concrete example. Take a typical £80,000 single-storey rear extension in the Midlands, funded by a £60,000 further advance on a remortgage. If you wait 12 months and assume build cost inflation of 6% — a blended midpoint of the BCIS general build cost index and trade rate rises — that adds £4,800 to your bill. Meanwhile, if mortgage rates fall by 0.5% on that £60,000 over 25 years, you save roughly £15 a month, or about £180 a year. Over the full loan term that’s around £3,500 in savings. Net position after a 12-month wait: roughly £1,300 worse off, before counting any tax changes, lost use of the space for a year, or the risk of further material shocks. That’s the kind of number that makes the decision clearer.
There are, of course, situations where waiting genuinely makes sense. If you’re inside an Early Repayment Charge window — a 3–5% ERC on £200k of fixed mortgage is £6,000–£10,000 — that changes the maths entirely. Similarly, if you’d be borrowing above 85% loan-to-value, rates jump sharply enough to tip the scales. And if your design isn’t past RIBA Stage 3, starting before plans are properly drawn up is the number one cause of cost overruns. But for most people in a stable property with decent equity, the numbers say go now rather than wait. The case for acting sooner is stronger than it’s been in years.
Where people get the maths wrong
I’ve seen the same mistakes crop up again and again when people run these numbers. Here are the three most common — and what to do instead.
Underestimating the full cost of moving
Most people focus on stamp duty and estate agent fees, but the list is longer than that. Conveyancing on the sale runs £900 to £1,800 plus VAT, and on the purchase another £900 to £2,000. Searches and disbursements add £300 to £700. A HomeBuyer or building survey is £400 to £1,500. An EPC for the property you’re selling is £60 to £120. Mortgage arrangement fees can be £0 to £2,000. Removals run £400 to £3,000. Add it all up and you’re looking at £3,000 to £10,000 in fees alone, on top of stamp duty. That’s money that disappears — it doesn’t go into equity or improvements.

| Cost Category | Typical Range | Notes |
|---|---|---|
| Stamp Duty (SDLT) | £0 – £40,000+ | Single biggest cost; varies by price band |
| Estate Agent Fees (sale) | 0.75% – 1.8% + VAT | On the sale price of your current home |
| Conveyancing (sale + purchase) | £1,800 – £3,800 + VAT | Two separate transactions |
| Surveys, EPC, removals, mortgage fees | £860 – £6,620 | Often forgotten in the initial budget |
Ignoring trade availability and lead times
This is the one that catches people off guard most often. Most FMB members are already fully booked through H1 2026, and around a third are booked into autumn 2026 or beyond. The construction workforce remains roughly 350,000 below pre-Brexit levels. Even a “wait” decision often means booking the trade today — because if you don’t, you won’t get a slot when you’re ready to start. I’ve seen people decide to wait six months, only to find that the builder they wanted is now booked for the next year. The smartest middle path is to design and tender now, lock the trade slot, and start when your numbers say go.
Overestimating how much value a renovation adds
Not every renovation recovers its cost. A premium loft conversion at £65,000 to £90,000 might not add that much to your home’s value if the ceiling height is tight or the staircase eats up too much floor space. A mid-range kitchen at £15,000 to £30,000 typically recovers well, but only if the rest of the house is in reasonable shape. The key is to match the scope of work to the ceiling price in your area. If every house on your street sells for £350,000, spending £80,000 on an extension won’t get you £430,000 — it’ll get you closer to £400,000. That’s still a gain, but it changes the return calculation. A realistic view of what adds value is essential before you commit.

The decision comes down to running your own numbers through a few specific checks. Here’s the process I’d follow if I were in your shoes.
Run the full move cost calculation
Before you do anything else, add up every cost of moving — not just stamp duty. Use the table above as a checklist. If the total is more than 10% of your current property’s value, renovating starts to look much more attractive. That £30,000 to £55,000 you’d spend on moving could instead fund a significant renovation that adds real value to your home. If you’re unsure about any of the legal or tax implications, it’s worth getting advice from a property lawyer who can walk you through the specific costs for your situation.
Check your mortgage position first
This is the single most important step. If you’re inside an Early Repayment Charge window, the penalty alone can wipe out any benefit of moving. A 3–5% ERC on a £200,000 fixed mortgage is £6,000 to £10,000 — that’s a new kitchen or a bathroom renovation right there. Similarly, if you’d need to borrow above 85% LTV to fund a move, the higher rates will eat into your monthly budget for years. If either of these applies, renovating is almost certainly the better option. If you’re not sure where you stand, a financial advisor can help you model the numbers.
Lock your trade slot now, even if you’re not ready to start
With 85% of builders already booked through H1 2026, waiting to find a builder until your plans are finalised is a recipe for delay. The smart move is to get your design to at least RIBA Stage 3 — detailed design — then start talking to builders. Get quotes, check availability, and put a deposit down to hold a slot. If you decide to wait, you’ve lost nothing but a small deposit. If you decide to go ahead, you’ve saved months of lead time. A regional perspective on trade availability can also help you understand what’s realistic in your area.
Plan for a 25% cost overrun buffer
A renovation is a 12-month financial stress test. Don’t start one if you can’t ride out a 25% cost overrun without breaking. That means having a contingency fund — ideally in cash — that covers unexpected structural work, material price spikes, or delays. If that sounds daunting, start with a smaller scope. A kitchen refresh at £8,000 to £15,000 is far less risky than a full two-storey extension at £100,000+. The key is to match the project to your financial resilience, not your wish list. A water leak detector is a small investment that can save you thousands if a pipe bursts during the work — it’s the kind of practical precaution that pays for itself.
