A 5% deposit can make the difference between continuing to save and having enough cash to consider buying now. For buyers researching 95% mortgage UK options, the headline is straightforward: the mortgage can cover up to 95% of the property value, while the buyer provides the remaining 5%. The harder question is whether the borrowing, property and monthly payments all fit the lender’s criteria.
For a first-time buyer, the deposit is only one part of the calculation. Income, committed spending, credit history and the property itself still matter, which is why our first-time buyer mortgage guide looks beyond the headline percentage and into the wider application.
95% mortgage UK: how does a 5% deposit work?
A 95% loan-to-value mortgage means the lender provides 95% of the value used for the mortgage calculation and you provide 5% as your deposit. On a £300,000 purchase, a 5% deposit is £15,000 and the mortgage required would be £285,000, assuming the lender accepts the property value and the full loan passes affordability and underwriting.
For comparison, increasing the deposit changes the amount being borrowed quite quickly. The figures below use the same hypothetical £300,000 property purely to show the arithmetic.
| Mortgage LTV | Deposit | Mortgage | Deposit % |
|---|---|---|---|
| 95% LTV | £15,000 | £285,000 | 5% |
| 90% LTV | £30,000 | £270,000 | 10% |
| 85% LTV | £45,000 | £255,000 | 15% |
95% mortgage UK: what does affordability change?
A 5% deposit does not mean a lender will automatically provide the other 95%. Mortgage affordability still considers verified income, existing financial commitments and normal household expenditure, with lenders also required to consider the effect of future interest-rate changes.
For a buyer whose deposit works but whose required mortgage is close to the limit of what their income supports, the problem may therefore be affordability rather than the deposit. Our article on what an online mortgage calculator cannot confirm explains why two applicants with similar salaries can receive different borrowing figures.
Is the government guarantee the same as a 95% mortgage?
No. A high loan-to-value mortgage is the product the buyer takes out, while the permanent Mortgage Guarantee Scheme is an arrangement between participating lenders and the government. The present scheme has operated since July 2025 and supports eligible lending above 90% and up to 95% LTV.
Importantly, the guarantee protects the participating lender against part of a qualifying loss; it does not remove the borrower’s responsibility for the mortgage. The scheme can support eligible first-time buyers and home movers throughout the UK, but participating lenders still apply their own underwriting and product criteria.
One useful distinction from the previous scheme is that the permanent scheme itself does not retain the old £600,000 property-value ceiling. That does not mean every lender will lend at 95% on a property of any value. Individual product limits, loan sizes and property rules can still be considerably narrower.
95% mortgage UK: when can lender criteria differ?
Lender criteria can differ even when two mortgages carry the same 95% LTV label. Property type, maximum loan size, income structure, credit history and whether the case is a purchase or remortgage can all affect which products remain available.
For that reason, we would not treat the deposit percentage as the whole case. A salaried buyer purchasing a conventional house can present differently from a company director buying a flat, even where both have exactly 5% available in cash. The lender still has to be comfortable with the borrower and the security.
What are the financial trade-offs of a smaller deposit?
Higher LTV borrowing can cost more because the lender is advancing a larger proportion of the property’s value. Moneyfacts’ UK averages on 1 September 2026 put two-year fixed rates at 6.09% for 95% LTV compared with 5.64% at 85% LTV, while five-year averages were 6.00% and 5.60% respectively.
Those are market averages rather than rates an individual applicant can expect. They do, however, show why the decision is not simply between buying now and waiting. A larger deposit may reduce the amount borrowed and open different pricing, while waiting to build that deposit has its own cost in time, rent and changing property prices.
A smaller starting equity position also leaves less room if the property falls in value. Negative equity occurs when the outstanding mortgage becomes greater than the property’s value, which can make selling or changing mortgage arrangements more difficult.
What alternatives can be considered if a 5% deposit is not enough?
For some buyers, moving to a lower LTV by saving more is one route. For others, the constraint is borrowing capacity rather than cash. A Joint Borrower Sole Proprietor mortgage can be relevant where another person’s income may support the application without that person becoming an owner, subject to the lender’s criteria and the legal implications being properly understood.
Family support can also take different forms. Some cases involve a gifted deposit, while others consider a guarantor structure; our guide to guarantor mortgages explains how that type of support differs from simply contributing cash. These are alternatives to compare, not automatic substitutes for a 95% mortgage.
What costs sit outside the 5% deposit?
The deposit is not the complete cash requirement for buying a home. Legal work, surveys or valuations, moving costs, mortgage-related fees and any applicable property tax can sit outside it, so keeping every available pound inside the deposit can leave little room for the transaction itself.
For buyers trying to establish the wider purchase budget, our explanation of Stamp Duty bands and who pays what covers one of the costs that may need to be considered separately. A solicitor or other appropriately qualified professional can confirm the legal and tax position for a particular purchase.
In Summary
A 95% mortgage UK buyer is considering more than a small deposit. The 5% figure determines the starting LTV, but affordability, the property, lender criteria, product pricing and the amount of cash left for other costs all affect how the case works in practice.
For some buyers, using 95% LTV may bring a purchase within reach sooner. For others, a larger deposit or a different family-support structure may alter the numbers enough to produce a different set of options. The useful comparison is the complete cost and structure rather than the deposit percentage on its own.
Frequently Asked Questions
The questions below cover the points we most often need to separate when looking at a low-deposit mortgage: the deposit itself, affordability, the government guarantee and what happens when circumstances differ from the standard case.
Is a 95% mortgage UK option only for first-time buyers?
No. A 95% mortgage UK option can also be available to home movers, depending on the lender and product. The permanent Mortgage Guarantee Scheme also supports eligible first-time buyers and home movers rather than being restricted only to people buying their first home.
Does having a 5% deposit guarantee mortgage approval?
No. The deposit establishes the proposed LTV, but the lender still assesses affordability, income evidence, expenditure, credit profile and the property being offered as security. A sufficient deposit can therefore coexist with an application that does not meet a particular lender’s criteria.
How much is a 5% deposit on a £300,000 property?
A 5% deposit on £300,000 is £15,000. A buyer borrowing the remaining £285,000 would be seeking a 95% LTV mortgage, before allowing for any separate purchase costs.
Does the government Mortgage Guarantee Scheme protect the borrower?
No. The guarantee is provided to participating lenders against part of their potential loss on eligible mortgages. The borrower remains responsible for making the mortgage payments under the terms of their loan.
Are 95% mortgages normally more expensive than lower-LTV mortgages?
Higher-LTV products often carry higher pricing because the lender is providing a greater proportion of the property’s value. Current market averages show that difference, although the actual product available to an individual borrower depends on their circumstances and lender criteria.
Can I remortgage at 95% LTV?
Some lenders may permit high-LTV remortgaging, but it is not universal. The permanent government scheme allows participating lenders to determine whether their participation covers certain remortgage lending, so individual product criteria need to be checked.
What happens if the lender values the property below my agreed purchase price?
A lower valuation can change the effective LTV because the lender bases its decision on the value it accepts for mortgage purposes. That may mean the available loan is lower than expected, leaving the buyer to reconsider the deposit, borrowing amount or purchase terms.
Does the 5% deposit include legal fees and other buying costs?
No. The deposit is the buyer’s contribution towards the property price, while legal fees, surveys, moving costs, product fees and any applicable tax can arise separately. The overall cash requirement can therefore be greater than 5% of the purchase price.
A low-deposit mortgage can solve one problem without automatically solving affordability or overall cost. We can compare the deposit, borrowing requirement and lender criteria together so the numbers are considered as one case rather than as separate headlines.
