In 2026, schemes at this entry price point are predominantly located in vibrant outer London regeneration hubs—such as Barking & Dagenham, Croydon, Bexley, Romford, and Hayes—where major infrastructure investment provides fast, direct connections to central transport terminals.
Every development under £300k in our catalogue is sold chain-free direct from leading UK housebuilders, complete with a 10-year structural warranty (NHBC, Premier Guarantee, or Checkmate). With modern insulation standards delivering EPC ratings of B or higher, these new build schemes offer substantially lower utility bills and maintenance costs compared to older second-hand housing stock.
FAQ: New Build Developments Under £300,000 in London
Yes. Full ownership opportunities under £300k are available in Outer London boroughs (Zones 4 to 6), notably in Barking Riverside, Croydon, Romford, and Bexleyheath. These developments feature high-specification modern homes with landscaped communal gardens and on-site transport connections.
With a 95% mortgage, a 5% deposit requires £15,000, while a 10% deposit requires £30,000. Several developers active in this price band offer deposit contribution packages (such as 5% developer-paid deposits) or participate in the Own New Rate Reducer scheme to lower initial payments.
Yes. Shared Ownership developments enable buyers to purchase an initial equity share (typically between 25% and 50%) of a newly built property, significantly reducing the initial deposit barrier while allowing future staircasing up to 100% ownership.
No. In England, first-time buyers pay 0% Stamp Duty Land Tax (SDLT) on residential purchases up to £425,000, meaning properties in sub-£300k developments are completely exempt from SDLT for eligible purchasers.
