A deposit is usually talked about as a percentage — 5%, 10%, 15% of the purchase price. But most buyers are saving a fixed amount of cash, not a percentage, and the same pot of savings buys a very different mortgage deal depending on where the front door is. On 2025 sale prices from HM Land Registry, a £30,000 deposit is enough to clear a 90% mortgage on the typical home in Manchester, Leeds or Birmingham — but in Kensington and Chelsea, the same £30,000 doesn't even reach the 5% most mainstream lenders ask for as a minimum.
This is the inverse of the usual way deposit coverage gets reported, which fixes the percentage and lets the cash figure move with the city (the deposit gap between the UK's cheapest and dearest cities). Fixing the cash instead shows what a saver's actual pot is worth once it meets a real mortgage market.
What £30,000 buys, city by city
Lenders set products in loan-to-value (LTV) bands, and the deposit percentage needed to unlock each one is the mirror image of the LTV: a 5% deposit buys a 95% mortgage, a 10% deposit buys a 90% mortgage, a 25% deposit buys a 75% mortgage or better, and so on. Measuring a fixed £30,000 against each city's 2025 median sale price shows which band it reaches:
| City | 2025 median price | £30,000 as % of price | Deposit tier reached |
|---|---|---|---|
| Kingston upon Hull | £143,000 | 21.0% | 80% LTV |
| Sunderland | £160,000 | 18.8% | 85% LTV |
| Liverpool | £182,000 | 16.5% | 85% LTV |
| Bradford | £187,348 | 16.0% | 85% LTV |
| Nottingham | £200,000 | 15.0% | 85% LTV |
| Newcastle upon Tyne | £209,075 | 14.3% | 90% LTV |
| Sheffield | £220,000 | 13.6% | 90% LTV |
| Birmingham | £239,000 | 12.6% | 90% LTV |
| Leeds | £250,000 | 12.0% | 90% LTV |
| Manchester | £253,000 | 11.9% | 90% LTV |
| England (median) | £300,000 | 10.0% | 90% LTV |
| Bristol | £350,000 | 8.6% | 95% LTV |
| Wandsworth | £650,000 | 4.6% | below the usual 5% minimum |
| Hammersmith and Fulham | £706,000 | 4.2% | below the usual 5% minimum |
| Camden | £780,000 | 3.8% | below the usual 5% minimum |
| Westminster | £890,000 | 3.4% | below the usual 5% minimum |
| Kensington and Chelsea | £1,192,250 | 2.5% | below the usual 5% minimum |
Figures are 2025 median sale prices for houses and flats (HM Land Registry Price Paid Data, category A transactions). No city in this list turns £30,000 into the best 75%-LTV-or-better tier — Hull comes closest at 80% LTV — while five of England's most expensive boroughs don't clear even the baseline 5% deposit most mainstream lenders require.
A smaller pot: £15,000
Halve the pot and the picture shifts down a tier almost everywhere. £15,000 is enough for a 90% mortgage only in Hull; every other city on the cheaper half of the ladder needs the full 95% LTV band, and the England median sits exactly on the 5% line.
| City | 2025 median price | £15,000 as % of price | Deposit tier reached |
|---|---|---|---|
| Kingston upon Hull | £143,000 | 10.5% | 90% LTV |
| Sunderland | £160,000 | 9.4% | 95% LTV |
| Manchester | £253,000 | 5.9% | 95% LTV |
| England (median) | £300,000 | 5.0% | 95% LTV |
| Bristol | £350,000 | 4.3% | below the usual 5% minimum |
| Wandsworth | £650,000 | 2.3% | below the usual 5% minimum |
| Kensington and Chelsea | £1,192,250 | 1.3% | below the usual 5% minimum |
At this level, Bristol and every London borough in the table fall short of the minimum deposit a mainstream mortgage usually asks for, before a buyer even gets to comparing rates.
A bigger pot: £50,000
At £50,000, the cheapest five cities move into the best tier on offer, while most of inner London only reaches what £15,000 bought in the North.
| City | 2025 median price | £50,000 as % of price | Deposit tier reached |
|---|---|---|---|
| Kingston upon Hull | £143,000 | 35.0% | 75% LTV or better |
| Nottingham | £200,000 | 25.0% | 75% LTV or better |
| Manchester | £253,000 | 19.8% | 85% LTV |
| England (median) | £300,000 | 16.7% | 85% LTV |
| Bristol | £350,000 | 14.3% | 90% LTV |
| Wandsworth | £650,000 | 7.7% | 95% LTV |
| Kensington and Chelsea | £1,192,250 | 4.2% | below the usual 5% minimum |
A £50,000 deposit in Hull leaves a £93,000 mortgage. At the Bank of England's latest quoted rate for a five-year fix at 75% LTV — 4.32%, unchanged since April 2026 — a 25-year repayment loan of that size works out at roughly £507 a month. The same £50,000 against Kensington and Chelsea's £1,192,250 median still doesn't reach a mainstream deposit at all; the quoted 4.32% rate applies to 75% LTV lending specifically, and lenders typically price higher-LTV products at a premium to it, so the gap between these two buyers is wider than the deposit figures alone suggest.
Why the tier matters, not just the cash
A £30,000 or £50,000 pot sounds like meaningful progress wherever it's saved. What it actually buys — a comfortable, better-priced mortgage band, or barely the minimum a lender will accept — depends entirely on the price of the home it's measured against. The same cash target that comfortably clears the best LTV tier in the North of England can fail to meet even the lowest-tier minimum in parts of London, without the saver doing anything differently. None of this changes what any individual buyer should do with their own savings; it only changes how far a fixed amount actually goes once it meets a specific local market. Try a postcode in the Homecost tool to see current sale prices and mortgage estimates for a specific street, and read how much deposit lenders typically expect in the deposit size guide or how far a fixed 5% deposit stretches nationally in where a 5% deposit buys the average home.
