Saving for a House Deposit Faster

A deposit is usually the single biggest hurdle to buying a first home. The good news is that with a clear target, the right account, and a few smart habits, most savers can move faster than they think.

Start with a target, not a vibe

Decide on a realistic price range for your first home and the deposit percentage you're aiming for (5%, 10% or 15% are the common bands). Multiply those together and you've got a number to aim at.

Our house deposit calculator turns that target into a monthly savings figure based on how soon you want to buy.

Use a Lifetime ISA if you qualify

If you're 18–39 and buying your first home in the UK (up to £450,000), a Lifetime ISA pays a 25% government bonus on up to £4,000 a year — that's up to £1,000 free per year.

It's one of the most generous savings boosts available, and it works alongside a standard cash or stocks & shares ISA.

Park the money where it earns

Cash sitting in a current account is losing value to inflation. A regular saver, easy-access account paying competitive interest, or a fixed-rate bond (if you're sure you won't need the money) will all do better.

If your timeline is short (under 3–5 years), stick to cash. Stocks can fall right when you need them.

Tighten the leaks

You don't need to live on rice and beans. Cancel subscriptions you've forgotten, switch energy and broadband when contracts end, and automate a fixed transfer to savings on payday so you don't see it.

Small, repeatable wins beat one heroic month of cutbacks every time.
