First-time buyers in London often misjudge the amount they need for a deposit by a long shot. The nationwide feeling is that a deposit should be around £30,000 – and you can double it in London. But, the reality is closer to £140,000 being a requirement in London, and that comes with a hefty mortgage at a time of high interest rates along with stamp duty. The alternative for some is to look towards elsewhere, and Barcelona is one on many buyers’ minds.
Two housing markets moving in opposite directions
London’s average house price stood at £554,022 in mid 2026, which is around double England’s overall average of £293,000. But remember, London’s housing stock has a much higher share of apartments than the rest of the country.
While national prices are up 1.8%, London is down 2.5% YoY, which could be a concern for some buyers because it fell 10 consecutive months in a row.
If we look at Catalonia’s own housing price index, it tells the opposite story, where over the same timeframe it’s up 10% YoY. Barcelona’s average property price is closer to£330,000. This is much more promising when protecting against the risk of falling into negative equity.
Why the local market rewards specialist guidance
For many thousands flocking to Barcelona to grab up property, it raises the question of where in Barcelona that money would actually go. Real Estate Barcelona – where if we take BCN Advisors’ own listings, built on fifteen years operating across Eixample, the Zona Alta neighbourhoods, the waterfront apartments of Diagonal Mar, and so on – covers a portfolio of hundreds of properties priced between €450,000 and €6 million.
In other words, this is the luxury market. Yet in London, a semi-detached house typically costs over £710,000 – and that’s an ordinary home. For the same money (€826,000) you’re getting a detached villa in a residential district or a modern apartment in a prime district like Eixample.
What that same money actually reaches per square metre
The averages, converted into one currency, makes this even clearer to see. Second-hand housing across the Barcelonès area sold at an average of €3,827.76 per square metre in 2024, or €2,882.05 per square metre in the wider provinces.
London, by contrast, averages £7,000 per square metre for houses and £7,300 per square metre for flats, which is roughly around €8,175 to €8,525. That’s roughly double the Barcelonès figure for the same money.
So, a deposit for a one bed flat in London becomes, easily, a deposit for a two bedroom flat in Barcelona – and likely in a more desirable district on top. This opens up more choice, not just in terms of properties, but neighbourhoods, along with an upwardly trending price index.
For those already with a London home, cashing out can mean upsizing. For the first-time buyers, Barcelona is around half as expensive per square meter. And while the costs of moving (taxes, legal fees, notary) is higher in Barcelona, you may not have to move many times if you can one-shot a suitable family home rather than climbing the ladder.
