Your London First Home: More Than Just a Dream in 2026
By John Williamson · Published · Updated
The short answer: first-time buyers in London usually find their best chance in the outer boroughs, places like Barking and Dagenham, Bexley, Croydon, Sutton, Havering and Hillingdon, where average prices sit well below the London average. Pick the commute you can live with first, then look along that line.
Before you trust any list, including this one, look up your own area. The UK House Price Index gives the latest average price for every London borough, and HM Land Registry's sold prices search shows what flats on a particular street actually went for.
Which London boroughs are cheapest for first-time buyers?
The outer east and south of London are consistently the most affordable. Buyers who've managed it usually started here:
- Barking and Dagenham: often the lowest average price in London. Barking Riverside now has its own Overground station.
- Bexley and Havering: quieter, more suburban, with fast trains into central London.
- Croydon: East Croydon has quick trains to London Bridge and Victoria.
- Sutton: suburban, with direct trains to Victoria and London Bridge.
- Hillingdon: Hayes & Harlington is on the Elizabeth line, and the borough has a lot of green space.
- Waltham Forest: Leyton and Leytonstone on the Central line. Prices have risen, but flats can still be found.
Prices change street by street, so check the sold prices before you book a viewing.
How much Stamp Duty will I pay as a first-time buyer in London?
Since 1 April 2025, first-time buyers in England pay no Stamp Duty on the first £300,000, then 5% on the part from £300,001 to £500,000. Above £500,000 the relief doesn't apply at all and you pay the normal rates. The full rules are on gov.uk, and our Stamp Duty calculator works out your figure in seconds.
If you're saving in a Lifetime ISA, the home must cost £450,000 or less to use the bonus. Details are on gov.uk.
What else do I need to budget for?
On top of your deposit, allow for a solicitor, a survey, mortgage fees and the move itself. Put your own numbers into the moving cost calculator so nothing catches you out on the day.
How do I know what I can borrow?
Start with the mortgage calculator for a rough idea, then get a mortgage in principle from a broker. Sellers take you much more seriously when you have one. MoneyHelper has a clear, free guide to how lenders decide.
How do I check an area before I commit?
Do the commute at rush hour, walk the street at night, and check the flat's energy rating on the EPC register. If it's a leasehold flat, ask how many years are left on the lease and what the service charge is. Take our viewing checklist with you.
What I'd do next
Pick two or three boroughs on a line that works for you, and tell homeowners there what you're looking for. With a free buyer profile on Pineapple Nest, owners in those streets can find you and message you directly, sometimes before their home ever goes on the market.
