Building Society Low Deposit Mortgage Guide UK

A low-deposit mortgage can mean a standard 95% LTV mortgage with a 5% deposit, a 98% or 99% mortgage requiring only a small cash deposit, or in a few cases a 100% mortgage where another form of eligibility or security replaces a normal deposit.

UK building societies currently offer several different routes. The important question is not simply which lender asks for the smallest deposit. You also need to check affordability, interest rate, product fee, property restrictions, income rules, mortgage term and the risk of having very little equity after completion.

Low Deposit Mortgage Quick Answers

Typical low deposit Many mainstream low-deposit mortgages start at a 5% deposit, giving a 95% LTV mortgage.
10% deposit A 10% deposit normally means 90% LTV and can open a wider choice of mortgages than borrowing at 95% LTV.
Very small deposit Some building societies currently offer specialist products around 98% or 99% LTV for qualifying first-time buyers.
No deposit 100% mortgages exist, but eligibility is narrow and the risk of negative equity is higher.
First-time buyers Many specialist low-deposit products are restricted to first-time buyers, though the definition differs between lenders.
New builds High-LTV limits can be lower for new-build flats or houses, so never assume a 95% product applies to every property.
Deposit is not the only test Income, expenditure, credit history, property type, mortgage term and lender affordability checks still apply.
Do not spend every pound You still need money for legal work, survey costs, moving, furnishings and an emergency buffer after completion.
Fast answer: if you have 5% saved, start by comparing 95% LTV mortgages. If you have less than 5%, look specifically at specialist £5,000-deposit, 98%, 99% or rent-history products rather than assuming every building society can lend at that level.

What Is a Low Deposit Mortgage in the UK?

A low-deposit mortgage lets you borrow a high percentage of the property’s value. The percentage you borrow is your loan-to-value ratio, usually shortened to LTV.

MoneyHelper says buyers usually need at least 5% to 10% of the purchase price as a deposit. Some specialist mortgages require less, while certain 100% mortgages can work without a traditional borrower deposit.

90% LTV 10% deposit
95% LTV 5% deposit
98% LTV 2% deposit
99% LTV About 1% deposit
100% LTV No conventional deposit
Why LTV matters: a larger deposit lowers the percentage you need to borrow. Lower-LTV mortgages generally have a wider choice of deals and can have lower interest rates than very high-LTV borrowing.

After opening this link:

  1. Read the section explaining how much deposit you normally need.
  2. Compare the deposit percentage with the property price you are considering.
  3. Read the warning about higher interest costs and negative equity on very high-LTV mortgages.
  4. Check the home-buying schemes section if saving the full deposit is the main barrier.

How Much Deposit Do You Need?

The same deposit percentage can mean very different cash amounts depending on where you buy. Use these examples as planning figures rather than mortgage quotations.

Property price
10% deposit / 90% LTV
5% deposit / 95% LTV
£150,000
£15,000 deposit
£135,000 mortgage
£7,500 deposit
£142,500 mortgage
£200,000
£20,000 deposit
£180,000 mortgage
£10,000 deposit
£190,000 mortgage
£250,000
£25,000 deposit
£225,000 mortgage
£12,500 deposit
£237,500 mortgage
£300,000
£30,000 deposit
£270,000 mortgage
£15,000 deposit
£285,000 mortgage
£400,000
£40,000 deposit
£360,000 mortgage
£20,000 deposit
£380,000 mortgage
A useful breakpoint: if you are only a small amount short of the next LTV band, saving a little longer can sometimes open a wider range of products. For example, £19,000 is a 9.5% deposit on a £200,000 property, while £20,000 gives a full 10% deposit and 90% LTV.

Building Society Low Deposit Mortgage Routes in 2026

These examples show how different building societies approach small deposits. They are not rankings and the products are not interchangeable. Availability, rates and criteria can change quickly.

Yorkshire Building Society

Up to 99% LTV £5,000 minimum deposit

YBS currently offers its £5k Deposit Mortgage exclusively to qualifying first-time buyers. It allows a minimum £5,000 deposit on eligible properties with a maximum property value of £500,000.

Important restriction: YBS states that this product is not available on new-build flats or houses and is not available in Northern Ireland.

Leeds Building Society

95% standard FTB range Start up to 98% LTV

Leeds Building Society’s current first-time buyer range includes 95% LTV mortgages. Its specialist Start range can currently go to 98% LTV, with a minimum deposit of 2% or £5,000, whichever is greater.

Current Start mortgages are not available on new-build properties and are subject to income, affordability and maximum-loan criteria.

Check Leeds first-time buyer and Start mortgages

Skipton Building Society

Up to 100% LTV Rent-history route

Skipton’s Track Record Mortgage is aimed at eligible renters and can allow borrowing with less than a 5% deposit or no deposit at all.

Skipton currently states that applicants must meet its rent-history and affordability requirements. The product is available in England, Scotland and Wales, but not Northern Ireland or the Isle of Man.

Check Skipton Track Record criteria

Nationwide Building Society

Up to 95% LTV Helping Hand

Nationwide offers 95% mortgage options and its Helping Hand range is designed for eligible first-time buyers who may need to borrow more relative to income.

Helping Hand currently allows up to 95% LTV on an eligible five-year fixed mortgage, subject to Nationwide’s affordability and product conditions.

Check Nationwide Helping Hand

Principality Building Society

Up to 95% LTV FTB England & Wales lending

Principality currently states that it can lend up to 95% LTV to qualifying first-time buyers.

Property type matters: its current lending criteria distinguish between standard property, new-build houses and new-build flats, so the maximum LTV can change with the property.

Check Principality first-time buyer mortgages

Coventry Building Society

95% LTV examples FTB products

Coventry’s current first-time buyer range includes products with a maximum 95% LTV, subject to the individual product’s maximum loan, property and borrower criteria.

Product fees, cashback, fixed periods and Early Repayment Charges vary, so compare the full product rather than choosing on the headline rate.

Current-product warning: a lender can withdraw a high-LTV product even while its general mortgage information remains online. Always reach the current product table or speak to the lender before assuming an advertised LTV is still available for new applications.

Is a 5% Deposit Enough for a Mortgage?

It can be. A 5% deposit means you need a 95% LTV mortgage, and several UK building societies currently support qualifying first-time buyers at this level.

Why 5% can help you buy sooner

  • You need to save less cash before buying.
  • You may reach home ownership sooner than waiting for a 10% deposit.
  • Several mainstream building societies operate at 95% LTV.
  • Some first-time buyer ranges include fee or cashback choices.

Why 5% can cost more

  • You borrow more of the purchase price.
  • High-LTV rates can be higher than lower-LTV equivalents.
  • You start with only a small equity cushion.
  • A fall in property value can make remortgaging harder.
Do not empty your savings account just to reach 5%. A deposit is only one part of the cash you need. Keep separate money for legal fees, searches, survey costs, removals, initial repairs and an emergency fund where possible.

Can You Buy With Less Than a 5% Deposit?

Yes, but this is a specialist part of the mortgage market. Current building-society examples include Yorkshire Building Society’s £5,000 deposit route and Leeds Building Society’s Start mortgage.

Route
Deposit
Important restriction
YBS £5k Deposit Mortgage
At least £5,000
First-time buyer only; maximum property value currently £500,000; no new builds.
Leeds Start Mortgage
2% or £5,000, whichever is greater
Current Start range is first-time-buyer focused and excludes new builds.
Skipton Track Record
Less than 5%, potentially zero
Eligibility uses rent history and other specific criteria; location restrictions apply.
Useful distinction: “small deposit” does not necessarily mean “easy approval”. Specialist products can have tighter rules around property type, income, rent history, first-time buyer status or affordability.

What About a 100% Mortgage?

A 100% mortgage means borrowing the full eligible value of the property, so there is no normal borrower deposit. These products are much less common than 90% or 95% LTV mortgages.

Skipton’s Track Record Mortgage is a current example designed around an applicant’s record of paying rent. Other family-assisted products may use family savings or property as additional security instead of requiring the buyer to provide the full deposit themselves.

100% does not mean zero cash needed. You can still need money for solicitors, searches, a survey, removals and other home-buying expenses. You also start with no deposit-created equity cushion.

Official SkiptonSkipton Track Record Mortgage

After opening this link:

  1. Read the homeownership, age, credit and location criteria first.
  2. Check the maximum loan currently permitted.
  3. Read how Skipton uses your recent rental payments when assessing the mortgage.
  4. Check whether your rent arrangement can be evidenced in the required way.
  5. Read the negative-equity and repayment risks before requesting a Decision in Principle.

What Building Societies Check Besides Your Deposit

Having the required deposit gets you into the correct LTV band. It does not mean the mortgage is affordable under the lender’s rules.

Gross annual income and type of employment.
Self-employed income history where applicable.
Loans, credit cards, car finance and overdrafts.
Childcare, maintenance and regular commitments.
Credit history and recent missed payments.
Source of the deposit.
Gifted-deposit evidence where family is helping.
Property type and valuation.
Mortgage term and age at the end of the term.
Residency and visa status where relevant.
Expected retirement income for later-life terms.
Whether the application meets product-specific criteria.
Affordability and deposit solve different problems. A £25,000 deposit will not make a £475,000 mortgage affordable if your income and commitments do not support the repayments. Likewise, strong income does not remove a product’s minimum-deposit rule.

Gifted Deposits: What to Prepare

Family help is common for first-time buyers. Most lenders will want to understand whether the money is a genuine gift, who is providing it and whether the donor expects repayment or an ownership interest.

Donor identity The lender or conveyancer may need identity and address evidence from the person giving the money.
Source of funds Bank statements or other evidence can be requested to show where the deposit money came from.
Gift declaration The donor may need to confirm that the money is not a loan and that they will not own part of the property.
Tell the lender early Do not describe borrowed money as savings. The source of your deposit forms part of the mortgage and legal checks.

Low Deposit Mortgages for New-Build Homes

New builds need extra attention because the maximum LTV can be different from an older property. A lender may accept 95% LTV on an established house but set a lower maximum for a new-build flat.

Leeds Building Society Its mainstream first-time buyer range currently includes up to 95% LTV on new-build houses, while the specialist Start mortgage excludes new builds.
Principality Current criteria state up to 95% LTV for residential new-build houses and up to 90% LTV for new-build flats.
Yorkshire Building Society The current £5k Deposit Mortgage is not available for new-build houses or flats.
Do not reserve a new build based only on a general mortgage calculator. Check that the lender accepts the exact property type, construction, tenure, purchase incentive and LTV before relying on the mortgage route.

Compare the Whole Mortgage Cost, Not Just the Initial Rate

Low-deposit mortgages can be expensive to compare badly. A deal with the lowest headline interest rate can still cost more once product fees and the mortgage amount are included.

Check the mortgage itself

  • Initial interest rate.
  • Length of the fixed or tracker period.
  • APRC.
  • Product fee.
  • Maximum LTV.
  • Maximum loan.
  • Early Repayment Charges.
  • Overpayment allowance.

Check buying costs separately

  • Conveyancing and searches.
  • Survey.
  • Mortgage valuation if chargeable.
  • Broker fee if applicable.
  • Removal costs.
  • Stamp Duty Land Tax or the equivalent property tax where applicable.
  • Insurance.
  • Immediate repairs and furnishings.
Fee example: a £999 product fee is proportionally much more significant on a £120,000 mortgage than on a £450,000 mortgage. Compare the total cost over the period you expect to keep the deal.

Why Negative Equity Matters More With a Tiny Deposit

Negative equity means your mortgage balance is greater than the value of your home. Starting with only 1%, 2% or 5% equity gives you less protection against a fall in property prices.

£250,000 Purchase price
£12,500 5% deposit
£237,500 95% mortgage
£230,000 Illustrative later property value after a fall

In that simplified example, the property value has fallen below the original mortgage amount. Actual equity will also depend on how much capital you have repaid by that point.

Negative equity can make selling or remortgaging harder. This is one reason a larger deposit can be valuable even when a lender is willing to offer a higher LTV.

How to Prepare for a Low Deposit Mortgage Application

Do the affordability work before you start viewing properties at the top of your budget. A Decision in Principle can help establish a realistic range, but it is not a final mortgage offer.

  1. Choose a realistic property-price range.
  2. Work out the exact cash deposit you can use without spending your emergency money.
  3. Calculate the resulting LTV.
  4. Check whether you need a standard 90%/95% mortgage or a specialist sub-5% route.
  5. Review your credit reports and correct genuine errors before applying.
  6. Prepare evidence of income and regular outgoings.
  7. Document where the deposit came from.
  8. Get a Decision in Principle where appropriate.
  9. Once you find a property, verify that the exact property type fits the lender’s criteria.
  10. Compare the rate, fee, APRC and ERC before submitting the full application.

Documents commonly worth preparing

Recent payslips.
Recent bank statements.
Proof of deposit savings.
Gifted-deposit evidence where applicable.
Identification.
Proof of current address.
Details of loans and credit commitments.
Self-employed accounts or tax evidence where required.
Rental-payment evidence for rent-history products.

Should You Save Longer for a 10% Deposit?

There is no universal answer. A 5% mortgage can let you buy sooner, while reaching 10% can reduce LTV to 90% and may provide more product choice or lower pricing.

Buying sooner may make sense when

  • You already have a proper emergency buffer.
  • The repayments remain comfortable after stress-testing your budget.
  • You expect to stay in the property for a reasonable period.
  • The available high-LTV deal is affordable after fees.
  • Waiting materially affects your circumstances.

Saving longer may be useful when

  • You are very close to the next LTV band.
  • A 95% mortgage leaves your monthly budget too tight.
  • You would otherwise have no emergency savings.
  • Your chosen property is difficult to finance at high LTV.
  • Your credit or income position is likely to improve soon.

First-Time Buyer Schemes and Savings Support

A low-deposit mortgage is not the only route. Depending on where you live and your circumstances, Shared Ownership, First Homes, Right to Buy or other local and national schemes may affect how much cash or borrowing you need.

A Lifetime ISA can also help eligible first-time buyers build a deposit, subject to the account’s age, contribution, withdrawal and qualifying-property rules.

Common Low Deposit Mortgage Mistakes

Using every penny for the deposit Completion is not the end of your costs. Keep room for legal bills, moving, repairs and unexpected household expenses.
Comparing rate only A lower rate with a large product fee can cost more than a fee-free alternative depending on the mortgage size and deal period.
Ignoring the property rules High-LTV criteria for flats, new builds and unusual construction can differ from standard houses.
Assuming a DIP guarantees approval A Decision in Principle is an indication. The full application still involves underwriting and property checks.
Borrowing the deposit secretly A loan used for the deposit affects affordability and must be disclosed where relevant. Do not describe borrowed money as savings.
Ignoring future remortgage risk If you begin at 98%, 99% or 100% LTV, a fall in property value can leave fewer remortgage choices later.
Choosing the longest term automatically A longer term can lower the monthly payment but can increase total interest substantially.
Changing finances before completion Taking new credit, increasing card balances or changing employment can affect affordability before the mortgage completes.

How to Compare Building Society Low Deposit Mortgages Properly

  1. Calculate your actual deposit and LTV.
  2. Separate mainstream 90%/95% options from specialist 98%/99%/100% products.
  3. Remove lenders that do not accept your property type or location.
  4. Check maximum loan and income rules.
  5. Compare initial rate and product fee together.
  6. Read the Early Repayment Charge schedule.
  7. Check whether the lender offers advice or an execution-only route.
  8. Consider how much cash remains after deposit and completion costs.
  9. Stress-test repayments against other household bills.
  10. Re-check the live product immediately before applying.
Better comparison question: instead of asking “who lends with the smallest deposit?”, ask “which available mortgage fits my deposit, income, property and monthly budget at an acceptable total cost?”

Building Society Low Deposit Mortgage FAQs

1. What is a low deposit mortgage?

A low-deposit mortgage lets you borrow a high proportion of the property’s value. A common example is a 95% LTV mortgage, where you provide a 5% deposit and borrow the remaining 95%, subject to affordability and lender criteria.

2. Can I get a building society mortgage with a 5% deposit?

Yes. Several UK building societies currently lend up to 95% LTV to qualifying borrowers, particularly first-time buyers. The exact rate, property rules, income requirements and maximum loan differ between lenders.

3. Can I get a mortgage with less than a 5% deposit?

Possibly. Yorkshire Building Society currently offers a £5k Deposit Mortgage with up to 99% LTV for qualifying first-time buyers, while Leeds Building Society’s Start range currently allows up to 98% LTV subject to its criteria.

4. Can I get a 100% mortgage from a building society?

Some specialist routes exist. Skipton Building Society’s Track Record Mortgage can currently allow eligible renters to borrow with little or no deposit. Eligibility rules are stricter than simply having sufficient income.

5. Is a 10% deposit better than a 5% deposit?

A 10% deposit reduces your mortgage to 90% LTV and can provide access to a wider range of products or different pricing than 95% LTV. Whether waiting to save more is appropriate depends on your budget, property plans and available mortgage terms.

6. Can I use a gifted deposit?

Many lenders accept qualifying gifted deposits, but the donor and source of money normally need to be documented. The lender and conveyancer may require confirmation that the money is a genuine gift rather than a repayable loan.

7. Are low deposit mortgages available on new-build homes?

Sometimes, but restrictions vary. Some 95% products accept qualifying new-build houses, while specialist very-high-LTV products can exclude new builds. New-build flats can also have lower maximum LTV limits than houses.

8. Why are high-LTV mortgages riskier?

You begin with less equity and borrow more of the property’s value. If house prices fall, you can be at greater risk of negative equity, which may make selling or remortgaging more difficult.

9. Does a Decision in Principle guarantee a mortgage?

No. A Decision in Principle is an initial indication based on the information available at that point. A full mortgage application still involves underwriting, affordability checks, credit assessment and valuation of the property.

10. Which building society should I use for a low deposit mortgage?

The relevant lender depends on your deposit, income, property, location and eligibility. Compare the mortgages you actually qualify for by LTV, interest rate, APRC, product fee, Early Repayment Charges and property criteria rather than choosing by lender name alone.
