For most first-time buyers, the deposit is the single biggest hurdle between renting and owning. It is also one of the most misunderstood parts of buying a home, because the honest answer to how much you need is more than the headline minimum, and the deposit is only one of several costs you have to save for. This guide explains how much deposit you really need in the UK, why a bigger one helps, and what else to budget for so you are not caught out.

It is written for UK first-time buyers who want a clear, realistic picture of what it takes to get on the ladder.

The Minimum Deposit

In practice, the usual minimum deposit for a first home is five per cent of the property price. Mortgages that lend the other ninety-five per cent do exist, but they are more limited, come with higher interest rates, and lenders look at them more cautiously. So while five per cent is the door, it is rarely the most comfortable way through it.

Why a Bigger Deposit Helps

Putting down more than the minimum makes a real difference, and it is worth understanding why.

As a rough rule, ten per cent is a common target that meaningfully improves your options, and fifteen per cent or more opens up the better rates.

What the Deposit Is a Percentage Of

The deposit is a percentage of the property price you agree, not of the mortgage. On a home priced at two hundred and fifty thousand pounds, a five per cent deposit is twelve and a half thousand pounds, ten per cent is twenty-five thousand, and fifteen per cent is thirty-seven and a half thousand. Working the numbers on the actual price range you are looking at tells you the real target you are saving towards.

The Costs Beyond the Deposit

The deposit is not the only money you need on completion. Budget for the extras, because they catch many buyers out.

Schemes That Can Help

Several routes can make the deposit more achievable. A Lifetime ISA lets eligible savers get a government bonus on money saved towards a first home, within the rules and limits that apply. Shared ownership lets you buy a share of a property and pay rent on the rest, lowering the deposit needed. Other schemes and family support, such as a gifted deposit or a guarantor arrangement, can also bridge the gap. Each has its own conditions, so check what fits your situation before relying on it.

How to Save a Deposit Faster

The Bottom Line

You can buy with a five per cent deposit, but ten to fifteen per cent gives you better rates, more choice and a stronger application, and the deposit is only part of the money you need on completion. Work out the real target for your price range, add the stamp duty, legal and survey costs, use the schemes you qualify for, and you turn a daunting number into a clear, achievable savings plan.
