How Much Deposit Do You Need for a UK Mortgage in 2026
A clear breakdown of how much deposit you actually need for a UK mortgage in 2026, including low deposit schemes, what affects the number, and how to set a realistic savings target.
Saving up for a house deposit in the UK often feels like the hardest part of buying a home, especially with prices where they are in 2026. The good news is that the amount you actually need depends heavily on the type of mortgage you go for, and a few newer low deposit schemes have made getting on the property ladder more realistic than most people assume. This guide breaks down exactly how much deposit you need, what affects the number, and how to work out a realistic target for your own situation.
How much deposit do you actually need
Most UK mortgages are described by their loan to value ratio, or LTV, which is the percentage of the property price the lender covers. Your deposit makes up the rest. A 90 percent LTV mortgage means a 10 percent deposit, while a 95 percent LTV mortgage means only a 5 percent deposit.
In practical terms, that means on a 250,000 pound property, a 10 percent deposit is 25,000 pounds, while a 5 percent deposit is only 12,500 pounds. The lower your deposit percentage, the higher your mortgage amount and usually the higher your interest rate, since lenders see low deposit borrowers as slightly higher risk.
Low deposit schemes worth knowing about
Several schemes exist specifically to help buyers with smaller deposits, and it is worth checking whether you qualify before assuming you need the traditional 10 to 20 percent.
- 5 percent deposit mortgages are widely available again from most major lenders, making a much smaller upfront amount possible for first time buyers with a stable income.
- 2 percent deposit mortgages have become more common through newer lending schemes aimed specifically at first time buyers who can afford monthly repayments but struggle to save a large lump sum. These come with their own eligibility rules and usually a higher interest rate to offset the lender's risk.
- Guarantor and family assisted mortgages let a family member offer savings or property as security, which can reduce or even remove the deposit requirement in some cases.
If you are exploring one of the very low deposit routes, our UK 2 percent deposit mortgage calculator shows what your repayments and total mortgage amount would actually look like before you commit to anything.
What affects how much deposit you will need
A few factors decide where you actually land within these ranges.
- Your credit history. A stronger credit score generally opens up better rates and sometimes lower deposit requirements, while a patchy credit history can push lenders toward requiring a bigger deposit.
- Property type and value. Some lenders restrict their lowest deposit products to certain property types or price brackets, so a very high value property may not qualify for the smallest deposit schemes.
- Your income and existing debt. Lenders assess affordability alongside deposit size, so your income relative to your existing commitments matters just as much as the deposit itself.
Do not forget the other upfront costs
The deposit is usually the biggest number, but it is not the only one. Buyers also need to budget for stamp duty, which varies depending on the property price and whether you are a first time buyer, along with solicitor fees, survey costs, and mortgage arrangement fees. Underestimating these extra costs is one of the most common mistakes first time buyers make when planning their savings target.
Our UK stamp duty calculator gives you an accurate figure for that cost specifically, so you can build a complete picture of what you need saved rather than just the deposit alone.
Working out a realistic savings target
A practical way to plan is to decide which deposit percentage you are aiming for based on your timeline and savings ability, then check what mortgage amount and monthly repayment that would actually leave you with. A smaller deposit gets you into a home sooner but usually means higher monthly payments and more interest paid over the life of the loan. A larger deposit takes longer to save but can unlock better rates and lower monthly costs.
Running the numbers both ways with our mortgage calculator and the home affordability calculator makes this comparison much clearer than trying to estimate it in your head.
Frequently asked questions
What is the minimum deposit for a UK mortgage in 2026?
Some lenders offer mortgages with deposits as low as 2 to 5 percent, though eligibility depends on your income, credit history, and the specific lender's criteria.
Is a smaller deposit always a bad idea?
Not necessarily. It can get you on the property ladder sooner, but it usually means a higher interest rate and higher monthly repayments, so it is worth comparing the real numbers before deciding.
Do first time buyers get any deposit advantages?
Many low deposit schemes and stamp duty relief are specifically aimed at first time buyers, so it is worth checking your eligibility for both before assuming the standard rules apply to you.
What other costs should I budget for besides the deposit?
Stamp duty, solicitor and conveyancing fees, survey costs, and mortgage arrangement fees all add up on top of the deposit itself.
How do I know what deposit I can realistically afford?
Comparing a few deposit percentages against your savings timeline and the resulting monthly repayment is the clearest way to see what fits your situation.
Final word
The deposit you need depends far more on the type of mortgage and scheme you choose than on a single fixed number. Before assuming you need to save 10 or 20 percent, check the low deposit options available and run the actual numbers for your situation. A clear target makes the whole savings process far less overwhelming.
