How to choose the best option for you
There's a romantic version of buying an older home. You get the keys, you've got a vision, a Pinterest board and a willing partner with a paint roller. Eighteen months later you're living off a microwave in the spare room, the small structural job has found friends, and you've learned that “characterful” is estate-agent for “the windows are original and so is the heat loss.”
There's a romantic version of new build too. Everything works, nothing is your problem, and the hardest decision you face is which tiles to pick for the ensuite.
Both are caricatures, and the truth sits somewhere in between. The honest answer to “new or old?” isn't a fact you can look up — it depends on your money, your time, your skills and how you feel about risk. This piece lays out the real numbers and the real trade-offs so you can decide for yourself. No spin about which is “better.” There isn't a universal better. There's only what's better for you.
How people are actually buying
Start with what's happening in the market, because it shapes everything that follows. According to Nationwide's Housing Affordability Report (January 2026), first-time buyer numbers are up — running about 20% above 2024 — as wages have edged ahead of house prices for several years running. More people are getting on the ladder.
The interesting part is how. Separate Nationwide research found that two thirds of first-time buyers chose a cheaper home precisely because it needed work. The catch is what happened next: three quarters of them ended up doing more than they'd planned, a quarter did much more, and nearly one in five took on major structural jobs they hadn't budgeted for. The spending told the same story — six in ten spent over £2,500 putting things right, and almost a third spent more than £5,000.
That doesn't make buying an older home a mistake. For plenty of people it's exactly right. But it does mean “cheaper” deserves a closer look, because a lower price on the window card is not the same as a lower cost over the years you live there.
What an older home gives you
Resale has real advantages, and it's worth getting them clear in our minds.
The biggest is location. Established homes sit in established places — near the centre, near the good schools, near the station. New developments go where the land is, which is often further out. If a particular postcode matters to you, an older home will often be the only way in, and that's a perfectly good reason to choose one. Older homes also tend to give you more for your money in floor space and garden, and they come with the character a new build can't fake: the fireplaces, the proportions, a front door unlike the forty others on the street.
Then there's the idea of adding value — and here it's worth slowing down, because this is where a lot of buyers fool themselves. Nationwide's research shows a well-judged extension or loft conversion can add up to 24% to the value of a typical three-bed. True, and tempting. But to build it you need the cash, upfront — tens of thousands of it.
The common belief that you can simply “put it on the mortgage” only holds if you have equity to borrow against: either a large deposit with room to increase the loan, or a home you already own that's risen in value enough to remortgage against. A first-time buyer who has just scraped together 5% has neither. No headroom, no spare cash after completion. So for most new buyers the value-adding project isn't a plan — it's a someday-maybe, while the home stays exactly as bought and the bills carry on regardless.
What a new home gives you
New build marketing has a habit of listing features and stopping there — “A-rated EPC,” “high-performance glazing,” “built to current regulations” — as if the words alone mean something. They only matter once you translate them into your actual life.
The energy efficiency is the one that hits your pocket every month. A new build is typically EPC A or B; an older home is very often a D. After your mortgage, energy is the largest cost of running a home, and on a new build that cost is built down into the fabric and fixed from the day you move in — no spending, no disruption. On an older home it's higher and it stays higher unless you pay to change it. And here's the quietly damning bit from that same Nationwide research: when buyers renovated, they spent on what they could see — kitchens, bathrooms, flooring, paint. Energy-efficiency work was the second-least common thing anyone paid for, at just 22%. A new kitchen photographs well; loft insulation doesn't. So the cold, expensive-to-heat house mostly stays cold and expensive to heat. Retrofitting it properly — insulation, full glazing, a modern heating system — is a five-figure job most owners simply never get round to. In a new build it's already done, already paid for in the price, and covered if it fails.
That cover is worth spelling out, because new build protection isn't one thing, it's three. For roughly the first two years the builder itself is on the hook for defects and snags — you report it, they fix it. For ten years a structural warranty (NHBC Buildmark or similar) insures the serious fabric of the building: foundations, walls, roof. And most major builders are signed up to the New Homes Quality Code, an independent standards regime with an ombudsman behind it, which sets out how you must be treated and gives you somewhere neutral to go if they fall short. Buy an older home and you have none of that. No builder standing behind it, no structural cover, no ombudsman. If something's wrong, finding it, fixing it and funding it are all yours.
The rest is the texture of moving in. You choose the kitchen, the tiling and the flooring before completion rather than living through the work afterwards — so the “you can't put your stamp on a new build” line is a myth. And then there's the chain. A first-time buyer of a new build has no chain at all — they're buying from the builder, and the builder isn't waiting on a purchase of their own. A home mover has only their own sale to manage; once that's done, there's nothing above them to collapse, no upward chain to fall apart at the eleventh hour. Compare that with resale, where chains are the norm and both upward (the seller's onward purchase) and downward (your buyer's mortgage, their buyer's mortgage) failure points are real risks every step of the way. The number of resale deals that fall through in the final fortnight, after months of cost and effort, is not small. With a new build, that whole category of pain mostly disappears. And nobody has lived there before you: no inherited quirks, no previous owner's odd DIY, no wondering what's behind the boxed-in corner. Small things on their own, but together they're the difference between a home and a project.
The thing the spreadsheet can't measure: Stress
Before we get to the sums, there's one factor worth naming because no calculation can capture it — and a lot of buyers, in our experience, underweight it until they've lived through the alternative.
Buying a new build is, for the most part, a calmer experience than buying resale. No upward chain. No worrying about whether the seller's seller's purchase will fall through. No survey throwing up an unexpected damp problem the week before exchange. And after completion, no decade of DIY weekends, surprise boiler failures, “while-we-had-the-floor-up” discoveries, or fights with builders you found yourself. The whole journey to completion is quieter, and so are the ten years that follow.
That isn't a small thing. It's months of sleep not lost, weekends spent on things you actually want to do, and a low background hum of no problems to solve right now instead of a perpetual list of jobs. Plenty of people would pay good money for that. In effect, when you choose new build, you are paying for it — and it's a perfectly rational thing to value. Stress minimisation rarely shows up on a comparison table, but it's one of the most genuine reasons to buy new, and we'd be doing you a disservice not to say so plainly.
The thing only new build can offer: Incentives
A quick word on deposits, because there's an old idea floating around that you can't get a low-deposit mortgage on a new build. That used to have real force — for years after the financial crisis many lenders capped new build houses at 85% or 90% loan-to-value while older homes could reach 95%. In 2026 that's largely history. Far more lenders now offer high-LTV mortgages on new build, including 95% deals needing just a 5% deposit; a handful still won't go above 85%, but they're increasingly the exception. There's even a small but growing band of zero-deposit options for first-time buyers — 100% LTV products from the likes of Skipton, Hanley Economic and a few others — available on both resale and new build, though typically with tighter eligibility (a clean rental track record, for instance), higher rates and a real risk of negative equity if prices wobble. They aren't for everyone, but they exist. Unless your financial circumstances are genuinely complex, the deposit you need should be much the same whether you buy new or old. (Knowing which lenders do what on new build, and whether a zero- or low-deposit route is right for you, is precisely our specialism — so this is one to talk through with us rather than assume.) The real financial edge of new build isn't an easier deposit; it's what comes next.
What new genuinely offers, and resale cannot, is a layer of incentives attached to the property — real money, available only because the seller is a builder with stock to move. The main ones:
- Builder deposit contribution. The developer puts a percentage of the price towards your deposit.
- Own New Rate Reducer. The builder's incentive budget is used to cut your mortgage rate for the initial fixed period.
- Gen H New Build Boost. A shared-equity arrangement (5% deposit, an 80% mortgage, and a 15% interest-free equity loan from Gen H) that boosts borrowing power while keeping monthly payments down. Currently only on selected builders' developments.
- Rezide. A private shared-equity scheme funded by Barratt Redrow and Persimmon (with QSix and Ahauz), supported by Barclays and TSB on the main mortgage. You put in 5%, take an 80% mortgage, and a 15% equity loan from Rezide bridges the gap. Currently only on selected Barratt Redrow and Persimmon developments in England.
- Part exchange. The builder buys your existing home, removing the chain entirely.
- Assisted move. The builder helps sell your current home, often covering the estate agent fees.
- Non-financial extras. Upgraded kitchens, flooring, carpets, white goods, sometimes the stamp duty paid.
There are a myriad of different cash and non-cash incentives on offer across the new build market, and working out which combination delivers the most value for your circumstances — your deposit, your income, your lender of choice, the specific plot — can get complicated quickly. Some incentives also affect how a lender views the deal, which matters more than buyers often realise. This is precisely the kind of detail where a specialist new build broker earns their keep: helping you see the wood for the trees, and making sure the package you reserve is genuinely the best one for you. It's a conversation worth having before you reserve, not after.
So what does new build really cost? The honest sums
Enough principle. Let's put pounds on it, using a realistic pairing: an older home at £295,000 against a comparable new build at £360,000. That roughly 22% gap is the well-documented “new build premium” — broadly in line with recent analyses of Land Registry data, though there's no longer an official figure (the ONS suspended its new-build price series because there aren't enough transactions to be reliable). Some of that premium is newness for its own sake; much of it is the efficiency, the warranties and the finished condition described above.
Both buyers are first-time buyers putting in 5% of their own cash, on a 35-year term, fixing for five years and then re-fixing for another five at 4.89% (with a £999 fee). We'll measure every pound that leaves each buyer's account over ten years — deposit, all mortgage payments, stamp duty and energy — and we'll assume both homes rise in value at the same average rate, so future growth cancels out and flatters neither side.
There's one decisive variable: whether the new build comes with a builder deposit contribution. Some form of incentive is the norm rather than the exception — though it's never guaranteed, and what's on offer depends on the builder, the development and the individual plot. We'll do this in two passes, and the order matters. First, we'll stress-test new build against the kindest reading of the resale we can plausibly write. Then we'll show how the same comparison looks for the way most people actually buy.
