Deposit Unlock scheme explained

Deposit Unlock was designed to help buyers purchase selected new-build homes with a smaller deposit. Instead of needing a larger deposit for a newly built property, eligible buyers could use the scheme to buy with a deposit from 5%, subject to lender and developer criteria.

However, Deposit Unlock has now closed to new completions. Outstanding mortgage offers issued before closure should continue to be honoured by the relevant lender. Existing customers who already secured loans with Deposit Unlock should remain supported, and their mortgages are not expected to be affected.

That means the scheme may still matter if you already have an offer in progress or are speaking to a developer, but buyers should be careful about relying on it without checking timescales first.

How Deposit Unlock works

Deposit Unlock was designed to make low-deposit new-build mortgages more available.

New-build homes can sometimes be harder to access with a small deposit because some lenders are more cautious at higher loan-to-value levels. Deposit Unlock helped by giving participating lenders extra reassurance when offering mortgages on selected new-build properties.

In simple terms, the buyer provided a smaller deposit, the lender assessed the application, and the property had to be part of the scheme through a participating developer. The buyer still needed to pass normal mortgage checks.

Deposit Unlock did not mean every new-build home was eligible. It only applied where the builder, lender, property and buyer met the relevant criteria.

Because the scheme has now closed to new completions, buyers should treat this as background information rather than an ongoing route. If you already have a mortgage offer linked to Deposit Unlock, the relevant lender should continue to honour it.

How Deposit Unlock could have affected your mortgage

Deposit Unlock was aimed at buyers with smaller deposits purchasing selected new-build homes. The example below shows how the numbers could have worked.

The buyer is borrowing 95% of the property value, which means the mortgage has a 95% loan-to-value, or LTV. LTV can affect the mortgage options, rates and lender criteria available. Learn more: Loan-to-value explained.

This is only a simplified example. Your actual position would have depended on the property, developer, lender criteria, income, credit profile and whether a valid mortgage offer was already in place before the scheme closed.

Because Deposit Unlock is no longer open to new completions, this section should be treated as background information rather than a current buying route.

Who Deposit Unlock was designed for

Deposit Unlock was aimed at buyers who wanted to purchase a selected new-build home but had a smaller deposit.

It was not limited only to first-time buyers. Some home movers were also able to use it, depending on the lender, property and developer criteria. However, the property usually needed to be a new-build home from a participating builder.

Because the scheme has now closed to new completions, most new buyers will need to compare other low-deposit or new-build mortgage options. If you already had a Deposit Unlock mortgage offer in place before closure, the key point is whether the lender will continue to honour it and whether the purchase can still proceed under that offer.

What properties are eligible

Deposit Unlock was designed for selected new-build homes from participating builders.

Availability depended on the developer, the specific development and the property itself. Some homes may have been eligible, while others on the same wider site may not have been. The lender also needed to accept the property and be comfortable with the valuation, warranty, build stage and completion timing.

Because Deposit Unlock has closed to new completions, most new buyers will now need to compare other low-deposit or new-build mortgage options. If you already had a Deposit Unlock mortgage offer in place before closure, check with the lender and developer whether the purchase can still proceed under that offer.

Benefits and things to consider

Deposit Unlock was designed to make selected new-build purchases more accessible with a smaller deposit. However, the scheme has now closed to new completions, so it is mainly relevant if you already have an outstanding mortgage offer or previously bought through the scheme.

Deposit Unlock vs 5% deposit mortgages

Deposit Unlock was one way to access a mortgage with a smaller deposit on a selected new-build home. However, it was not the only possible low-deposit route.

A standard 5% deposit mortgage usually means buying with a 95% loan-to-value mortgage, subject to lender criteria. It may be available on a wider range of properties, depending on the lender, although new-build rules can vary.

The key difference is that Deposit Unlock was tied to participating developers and selected new-build homes. A standard 5% deposit mortgage may offer more flexibility, but not every lender will offer the same terms on new-build houses or flats.

Deposit Unlock vs other new build incentives

Some new-build homes come with developer incentives, such as contributions towards costs, upgraded fittings, deposit support or access to a specific mortgage scheme.

Deposit Unlock was different because it focused on helping buyers access a low-deposit mortgage on selected new-build homes. Other incentives may reduce upfront costs, but they may not reduce the deposit requirement in the same way.

Lenders may treat incentives differently. Some incentives need to be disclosed and could affect the valuation, mortgage offer or maximum borrowing. That is why it is important to check how any incentive works before you reserve the property.

What to check before relying on Deposit Unlock

Because Deposit Unlock has now closed to new completions, most new buyers will need to compare other low-deposit or new-build mortgage options.

However, if you already had a Deposit Unlock mortgage offer in place before closure, it is important to check the practical details before assuming the purchase can still proceed as planned.

That includes:

• whether your mortgage offer is still valid
• whether the lender will continue to honour the offer
• whether the property still meets the lender’s criteria
• whether the developer is still progressing the sale under Deposit Unlock
• whether the property can complete within the required timescale
• what happens if completion is delayed
• what alternative mortgage options are available if the route no longer works

If the timescale is tight, it is sensible to compare other mortgage routes at the same time rather than relying on one option. This can help you avoid losing time if the property, lender or completion date no longer fits the original Deposit Unlock arrangement.

How Muttuo Mortgages can help

Deposit Unlock helped some buyers access selected new-build homes with a smaller deposit. However, it has now closed to new completions, so it is no longer a standard route for most new buyers.

If you already had a Deposit Unlock mortgage offer in place before closure, the key question is whether the lender will continue to honour it and whether the purchase can still proceed under that offer.

If Deposit Unlock is no longer available for your purchase, you may need to compare other low-deposit or new-build mortgage options.

Treat Deposit Unlock as time-sensitive

Muttuo Mortgages can help you understand what low-deposit new-build mortgage options may still be available.

That might include reviewing the property, checking lender criteria, comparing 5% deposit mortgages and looking at other new-build mortgage routes before you commit to a purchase.

As a whole-of-market mortgage broker, Muttuo can also help you compare alternatives such as gifted deposits, family-assisted options or standard new-build mortgage products.

The aim is to help you move from a developer conversation to a clearer mortgage plan, so you understand what is realistic before you reserve or commit to a new-build property.
