And that includes London, it lists "excluding London" as £65k.
People overestimate how much senior devs in the UK earn, even after knowing they're not well paid, my usual response to hearing we should be earning £90k+ is, "well give us a job then"!
A friend is making about £180k / yr in London, and they bought a house recently in London. I think that's a lot, and his wife also makes a similar amount, slightly more. That seems to be the minimum, otherwise you're a renter for life. Pretty nuts.
A salary of £180k put you in the 98th percentile of UK salaries in 2024 (99th percentile was only a little higher at £207k) [1]. With a household income approximately doubling that, i'd suggest your friend is in an even smaller minority.
The average house price in London in July 2025 was £565k [pp33 - 2].
There is not being able to afford something and then there is not being able to afford exactly what you want.
Partly depends on what you mean by "London". I don't want to work for FAANG/AI/finance/gambling so our combined salary is well under the 180 figure. Yet we bought a 2-bed terraced house with a garden and driveway in south-west London (technically Surrey, but a London borough) just over five years ago. It's still 20 mins to Waterloo and most of central London is under an hour away. As we pay off the mortgage we should be able to further upsize over the years. It's not ideal, but it works.
That is an extremely high salary, and very far from the minimum required to buy, even on your own. A dual £350k income is truly astonishing. You could buy most houses in London in cash after saving for 5 years.
What? No that will not allow you to buy "most houses in London in cash after saving for 5 years" unless you live far out of town in a tiny place and eat plain rice for 5 years, and even then it'll be long odds.
First, you'll take home slightly over half of that net of various taxes and deductions, but let's be generous and say your take-home is 200k. You live very frugally, don't go out, don't really buy anything and keep your costs at 50k a year, including rent (!). That leaves you with 150k a year, so after 5 years you have 750k. This allows you to buy a modest 2-3 bed row house with a postage stamp sized garden in one of the less desirable areas of the city.
If you want something that doesn't look like a shed, you are looking at 1 million pounds and up, more like 1.5 million. If you want in a nice area and large garden, make it 2 million.
