Buy with 5% deposit in the UK: adviser led Help to Buy alternatives

IMPORTANT: YOUR HOME MAY BE REPOSSESSED IF YOU DO NOT KEEP UP REPAYMENTS ON YOUR MORTGAGE.

First-time buyers looking beyond Help to Buy generally have five practical routes: the Lifetime ISA, Shared Ownership (including the Right to Shared Ownership), First Homes, the Mortgage Guarantee Scheme and, for buyers in Wales, Help to Buy Wales. Savers with time on their side should start with the Lifetime ISA, social housing tenants should check Right to Shared Ownership, and buyers with a small deposit but stable income should compare the Mortgage Guarantee Scheme against Shared Ownership. Eligibility and regional availability vary by nation, so check official guidance or speak to a regulated adviser before committing.

TL;DR:

• The Lifetime ISA is ideal for savers under 40 with a steady savings plan, but it has a strict property price cap of 450,000 pounds and penalties for early withdrawal before age 60.
• Shared Ownership allows buying a percentage of a property with ongoing rent and service charges, and staircasing costs vary with each additional share purchased.
• The Mortgage Guarantee Scheme enables buying outright with a 5% deposit supported by a government guarantee, but not all lenders participate, and rates differ.
• First Homes provide discounts between 30% and 50% on new-builds for eligible buyers with household income caps, but stock is limited and varies by location.
• Regional schemes like Help to Buy Wales still operate in Wales until March 2027, while Scotland and Northern Ireland have their own distinct programs and rules.

Which alternative suits your situation

Each scheme solves a different problem: some help you save faster, others reduce how much you need to borrow, and some simply widen the pool of lenders willing to accept a small deposit. Matching the right scheme to your situation avoids wasted paperwork and missed deadlines.

• Lifetime ISA: best for buyers under 40 who can save steadily; caution is the strict £450,000 property price cap and penalties for early withdrawal.
• Shared Ownership: best for buyers who cannot afford full market value but want a foot on the ladder; caution is ongoing rent and service charges alongside your mortgage.
• Right to Shared Ownership: best for eligible housing association or council tenants; caution is that availability depends on your landlord and tenancy type.
• First Homes: best for buyers who qualify for a new-build discount in their area; caution is limited stock and household income caps.
• Mortgage Guarantee Scheme: best for buyers with a stable income and a 5% deposit who want to buy outright rather than share ownership; caution is that not every lender offers the same terms.
• Help to Buy Wales: best for buyers purchasing a new-build home in Wales; caution is that it does not apply in England or Scotland.

Read the sections below for the detail behind each option, including eligibility rules, costs and the practical steps involved.

Lifetime ISA: mechanics, limits and practical use for first-home purchases

The Lifetime ISA remains one of the more straightforward tools for first-time buyers because it rewards saving with a government top-up rather than requiring you to share ownership of the property. Anyone aged 18 to 39 can open one, and contributions of up to £4,000 a year attract a 25% government bonus, which counts towards the overall £20,000 annual ISA allowance for the 2026/27 tax year.

• You must be a first-time buyer and the property must be your only or main residence.
• The ISA needs to have been open for at least 12 months before you can withdraw the bonus without penalty for a home purchase.
• Your conveyancer applies for the bonus on your behalf as part of the purchase process.

Up to £1,000 a year in government bonus is available on the maximum £4,000 annual contribution, which can meaningfully boost a deposit over several years of saving.

The property price cap is £450,000, and this applies to the full market value of the home, not just the share you are buying. That matters for Shared Ownership purchasers: even if you are only buying a 25% share, conveyancer guidance confirms the cap is assessed against the whole property's value, not your slice of it. Withdrawing funds for anything other than a first home before age 60 triggers a withdrawal charge, so treat the LISA as a dedicated house-buying account rather than general savings. If you already hold a Help to Buy ISA, you can transfer it into a Lifetime ISA, but you cannot use the bonus from both schemes on the same purchase.

Shared Ownership and Right to Shared Ownership explained

Shared Ownership lets you buy a percentage of a property, generally starting from a low share up to about three-quarters, and pay rent to a housing association on the remainder. Homes England guidance sets out affordability assessments and RICS valuations as standard parts of the process, and encourages buyers to purchase the largest share they can comfortably afford. Right to Shared Ownership extends similar terms to eligible housing association and council tenants moving into new-build homes.

1. A registered provider or your existing landlord assesses your income and outgoings to confirm what share you can afford.
2. You arrange a mortgage for your share through a lender that offers shared ownership products, with a deposit typically based on that share's value rather than the full price.
3. Your conveyancer handles the lease, which sets out rent on the unowned share, service charges and any ground rent.
4. You can staircase, buying further shares over time, though each purchase involves a new valuation and legal fees.

Pro Tip: Ask your housing provider for the staircasing cost structure in writing before you exchange, since fees and valuation charges can add up over several purchases.

Service charges and rent are payable alongside your mortgage from day one, so factor both into your monthly budget rather than just the mortgage repayment.

First Homes and the First Homes Fund: discounted new builds

First Homes gives eligible first-time buyers in England a discount, typically between 30% and 50%, off the market price of specific new-build homes, with the discount passed on to future buyers when the home is resold. Household income is capped, commonly at £80,000, rising to £90,000 in London, and you must be able to secure a mortgage or savings covering at least half of the discounted price.

• Discounts and income caps are set locally, so check the specific development's terms before assuming eligibility.
• The discount is fixed as a percentage and stays with the property on resale, keeping it affordable for the next first-time buyer.
• You apply through the developer or local authority marketing the scheme, and stock is limited to specific new-build sites.
• Additional legal and valuation fees apply as with any new-build purchase, on top of the discounted price.

Because First Homes stock is tied to specific developments, availability depends heavily on what is being built in your area at the time you are looking.

Mortgage Guarantee Scheme: high-LTV mortgages for small deposits

The permanent Mortgage Guarantee Scheme, launched in July 2025, supports lenders in offering mortgages at 91% to 95% loan-to-value, meaning a deposit as small as 5% can be enough to buy outright rather than share ownership with a landlord.

• The government guarantee sits behind participating lenders, encouraging them to offer higher LTV products they might otherwise avoid.
• Not every lender takes part, and the exact rates, fees and affordability criteria vary between those that do.
• Standard affordability assessments still apply, so your income, credit history and existing commitments all affect what you can borrow.

For buyers who want full ownership from day one and can meet a lender's affordability test, a high-LTV mortgage under this scheme can be more straightforward than Shared Ownership, since there is no lease, no rent on an unowned share and no future staircasing costs. The trade-off is a larger loan relative to the property's value, which affects your monthly payments and how quickly you build equity.

Regional and legacy schemes across the UK

Scheme availability differs sharply by nation, and relying on a single national summary can lead you to miss options or waste time on ones that no longer apply where you live.

• Help to Buy Wales has been extended to 31 March 2027 and remains open to new-build buyers in Wales, while the equivalent scheme is closed to new applications in England and Scotland.
• Scotland offers its own routes, including New Supply Shared Equity, where the Scottish Government typically retains 20% to 40% of the property while you own the majority share.
• Scotland's First Homes Fund carries tight timing rules: you generally need an accepted offer but cannot yet have concluded missives, so close coordination between your solicitor and adviser matters.
• Northern Ireland runs its own affordable homeownership schemes separately from England, Wales and Scotland, so check the relevant devolved administration's guidance directly.

A practical checklist before you commit to a scheme

Before signing up to any scheme, work through the same set of questions regardless of which option you are leaning towards. This keeps the comparison fair and stops an attractive headline discount from masking a less attractive ongoing cost.

1. Confirm your eligibility against age, income, first-time buyer status and, for Shared Ownership, tenancy requirements.
2. Work out the minimum deposit or stake required and how that compares across the schemes you qualify for.
3. Check whether any price cap applies to the full market value of the property or only to your share.
4. Add up ongoing costs including rent on any unowned share, service charges, ground rent and mortgage interest.
5. Ask what your exit options look like, including staircasing costs and any restrictions on selling.

Pro Tip: Bring three years of accounts or payslips, your deposit source and a copy of any scheme eligibility letter to your first adviser appointment, since this is what most lenders ask for first.

When talking to lenders, ask directly what LTV bands they support and whether affordability is assessed on your share alone or the full property value. When talking to housing providers, ask for the staircasing fee schedule and any restrictions on subletting. When talking to conveyancers, ask how long the lease review typically takes and what it will add to your timeline.

If you can comfortably save over several years and stay under the £450,000 cap, a Lifetime ISA rewards patience with a straightforward bonus. If you need to move sooner and your deposit is thin, a high-LTV mortgage under the Mortgage Guarantee Scheme or a Shared Ownership purchase are the more immediate routes, and which suits you best depends on whether you would rather own outright with a bigger loan or own a smaller share with a smaller one.

Costs and typical timelines you should budget for

Every route to homeownership carries upfront and ongoing costs beyond the price of the property itself, and these vary by scheme.

• Solicitor and conveyancing fees typically apply regardless of scheme, alongside a mortgage valuation fee charged by your lender.
• Shared Ownership and Right to Shared Ownership purchases add a RICS valuation cost each time you staircase, plus ongoing rent and service charges from completion.
• First Homes and new-build purchases under the Mortgage Guarantee Scheme may carry standard new-build warranty and management fees on top of usual conveyancing costs.
• Applications for Shared Ownership and Right to Shared Ownership involve an affordability assessment stage before you can proceed to mortgage application, which adds time to the process.

Timelines depend heavily on the scheme and the property chain involved. A straightforward Mortgage Guarantee Scheme purchase can move at the same pace as any standard mortgage application, while Shared Ownership and First Homes purchases often take longer because of the additional eligibility checks, provider assessments and, for new builds, construction completion dates. Build in extra time for any scheme with a housing association or local authority step, since these assessments do not move at the same speed as a private lender.

Staircasing, resale and remortgaging: what to plan for

How you buy affects how easily you can sell, remortgage or move later, and this is often overlooked in the excitement of getting on the ladder.

• Staircasing to buy further shares in a Shared Ownership property involves a new valuation each time, and rising property values mean later shares can cost more per percentage point than your first purchase.
• Selling a Shared Ownership property usually means the housing provider has a right to find a buyer first, which can affect how quickly you can sell and at what price.
• Lenders assess remortgage applications on shared ownership or equity loan properties differently, since the security they hold is over a share rather than the whole property, and not all lenders offer these products.
• A high-LTV mortgage under the Mortgage Guarantee Scheme carries the standard risk of any small-deposit purchase: if property values fall, you could move into negative equity faster than a buyer with a larger deposit, so stress-test your affordability against a potential rate rise before committing.

When to get regulated mortgage advice

Complex incomes, whether from self-employment, contracting, bonuses or a professional role with variable pay, often need a lender that looks beyond a simple payslip multiple. This is where a specialist, regulated adviser earns their fee, matching your income structure to lenders who will actually accept it rather than leaving you to apply and get declined.

Haven Mark Advisers assigns a single dedicated adviser for the whole process, from initial eligibility checks through to mortgage offer, with transparent fees agreed upfront and proactive case management throughout. It is worth speaking to an adviser before you make an offer, to confirm which schemes you actually qualify for, and again as soon as any offer becomes subject to mortgage, since delays at that stage can put a purchase at risk. Read more about the firm's approach for first-time buyers.

Other government grants and local schemes worth checking

Beyond the headline national schemes, some local authorities and housing associations run their own affordable homeownership grants and discount schemes, often tied to specific developments or key worker status. These are typically smaller in scale and more targeted than national programmes, so they rarely appear in general searches for Help to Buy alternatives.

Local authority-led shared ownership and rent-to-buy schemes sometimes run alongside the national Shared Ownership model, with eligibility rules set by the individual council or housing association rather than a single UK-wide standard. Some regions also offer discounted homes for key workers such as nurses, teachers and police officers, again administered locally rather than nationally. Because these schemes are set and funded locally, availability changes frequently and can disappear or reappear as funding is allocated, so check with your local authority's housing department directly rather than relying on national scheme summaries. If you are buying a new-build home, ask the developer directly whether any local discount scheme applies to that specific site, since this information does not always appear in the standard property listing.

Comparing the main options at a glance

Choosing between these routes comes down to how much deposit you have, whether you are comfortable sharing ownership, and where in the UK you are buying.

Each option suits a different financial starting point rather than one being universally better, which is why matching the scheme to your own deposit, income and location matters more than chasing whichever scheme is best known.

Reducing the cost of a low-deposit mortgage

Buyers putting down less than 25% typically face higher interest rates than those with larger deposits, and some products carry additional fees to reflect the lender's higher risk. There is no direct UK equivalent to the US-style private mortgage insurance premium, but the practical effect, a higher cost for borrowing at a higher loan-to-value, is similar.

A few practical steps can reduce that cost over time. Building your deposit even slightly, from 5% to 10%, often unlocks a meaningfully better rate band, so it is worth checking whether waiting a few months to save more actually costs less overall than the higher rate on a smaller deposit. Some lenders also offer schemes where a family member's savings act as additional security, reducing the rate you pay without you needing a larger deposit yourself, though these products vary significantly between lenders. Overpaying your mortgage once you are on a standard rate, where your mortgage terms allow it, gradually reduces your loan-to-value and can put you in a better position to remortgage onto a lower rate later.

Family support and shared equity partnerships

Beyond the government-backed schemes, some buyers combine a family loan or gift with a standard mortgage to reach a workable deposit. A family member might lend money formally, with a signed agreement setting out repayment terms, or provide a gift that your lender will want documented as non-repayable, since undisclosed loans can affect your mortgage application. Some lenders also offer family-assisted mortgage products where a relative's savings or property act as security rather than being handed over as cash, which can help buyers who have the income to afford repayments but not yet the deposit.

Private shared equity partnerships, where a third party takes a stake in the property in exchange for a share of future value growth, exist outside the government-backed Shared Ownership model, but terms vary considerably between providers and need careful legal review before signing anything. Whatever route you take, be transparent with your lender about the source and structure of any family contribution, since undisclosed arrangements can delay or derail a mortgage application at a late stage.

What can go wrong: risks worth weighing up

Every alternative to Help to Buy carries its own set of risks, and understanding them before you commit matters as much as understanding the benefits.

Shared Ownership and equity loan arrangements can make it harder to sell quickly, since not every buyer wants to take on a lease with rent obligations, and your housing provider's right to find a buyer first can slow a sale down further. High-LTV mortgages under the Mortgage Guarantee Scheme leave you more exposed to negative equity if property values fall, since you have less of a buffer between your loan and the property's value. Lifetime ISA penalties for non-qualifying withdrawals can be significant, so treat the account strictly as a house fund rather than a flexible savings pot. First Homes discounts stay with the property permanently, which protects future affordability but also means you will not benefit from selling at full, undiscounted market value later. Family-backed arrangements, whether loans or informal equity partnerships, can create complications if personal circumstances change, so put agreements in writing from the outset rather than relying on informal understanding.

FAQ

Is Help to Buy still a thing in the UK?

The original Help to Buy equity loan scheme is closed to new applications in England and Scotland. Help to Buy Wales remains open and has been extended to 31 March 2027 for buyers purchasing eligible new-build homes in Wales.

What is the 28/36 rule in the UK?

The 28/36 rule is a US budgeting guideline and is not a standard used by UK mortgage lenders. UK lenders assess affordability individually, based on your income, existing debts and outgoings rather than a fixed ratio, so speak to a regulated adviser about what a specific lender is likely to accept.

What are some affordable alternatives to buying a house in the UK?

Practical alternatives to a standard full-price purchase include Shared Ownership, where you buy a share of the property and pay rent on the rest, and using a Lifetime ISA to build a deposit with a government bonus attached. Renting while saving, or exploring First Homes discounts on eligible new builds, are also common routes for buyers not yet ready for full market value.

What are the new Help to Buy schemes in 2026?

There is no new national Help to Buy scheme in England or Scotland; the main current alternatives are the Lifetime ISA, Shared Ownership, First Homes and the Mortgage Guarantee Scheme, which supports 91% to 95% loan-to-value mortgages. Help to Buy Wales continues to operate for eligible new-build purchases in Wales.

How much does regulated mortgage advice cost?

At Haven Mark Advisers, the purchase mortgage service is charged at £495 payable on completion, with fees agreed transparently before any work begins. The exact service and fee depend on whether you are buying, remortgaging or switching products, so check current terms before proceeding.
