£350m Support for Smaller Housebuilders: What the New ENABLE Build Facility Means for UK Housing Supply

The increase, announced on 6 October 2026, adds £200 million to an existing £150 million ENABLE Build guarantee facility.

The scheme is designed to support Shawbrook in providing development finance and bridging lending to smaller housebuilders across the UK.

What is ENABLE Build?

ENABLE Build is a British Business Bank programme designed to encourage additional lending to viable smaller housebuilders.

Rather than simply handing £350 million directly to developers, the programme provides a guarantee facility that supports lending by participating finance providers.

In this case, Shawbrook is the finance provider.

The increased facility therefore gives the bank additional capacity to support smaller developers with development and bridging finance.

Why does smaller-builder finance matter?

The UK housing market has a long-standing challenge around housing supply.

Large housebuilders deliver a substantial proportion of new homes, but smaller and regional developers also play an important role in bringing sites forward.

Smaller developers can face greater difficulty obtaining development finance because lenders must assess construction risk, planning risk, sales risk and the financial strength of the development company.

Access to specialist finance can therefore determine whether a viable development proceeds or remains stalled.

£700m of lending expected over the lifetime of the facility

According to the British Business Bank, around £700 million of lending is expected to be included over the lifetime of the expanded facility.

The bank said that around £240 million of lending between December 2024 and June 2026 had already been included in the existing ENABLE Build transaction, supporting around 1,200 homes.

The wider ENABLE Build programme had supported more than £2 billion of finance to smaller housebuilders by March 2026, helping to deliver more than 10,000 homes, according to the British Business Bank.

The importance of bridging finance

Development projects do not always follow a simple funding timeline.

A developer may need finance to acquire a site, complete planning-related work, begin construction or refinance an existing facility.

Bridging finance can provide short-term funding where there is a clear exit strategy.

For example, a developer may use development finance to construct a scheme and then repay the facility through property sales or longer-term refinancing.

The availability and cost of such funding can significantly influence development viability.

Higher borrowing costs remain a challenge

The new facility arrives against a difficult financing backdrop.

Average UK five-year fixed residential mortgage rates reached 6% on 5 October, illustrating the broader pressure in borrowing markets.

Development finance is not directly equivalent to residential mortgage pricing, but wider funding costs influence the economics of property development.

When financing becomes more expensive, developers must account for higher interest costs within their project budgets.

That can affect land values, construction programmes and the viability of marginal schemes.

Housing supply and smaller developers

The British Business Bank said the expanded facility should allow Shawbrook to support more housebuilders and strengthen the pipeline of housing supply.

That could be particularly significant for developments that are too small to attract the same financing structures as major national housebuilders.

Regional developers can also play an important role in smaller towns and communities where large-scale schemes may not be commercially attractive.

What could the facility mean for developers?

For smaller housebuilders, additional lending capacity could provide greater access to:

• Development finance

• Bridging finance

• Site acquisition funding

• Construction funding

• Refinancing

• Working capital around development projects

However, the facility does not remove normal lending requirements.

Developers still need viable projects, credible financial structures, appropriate planning and an acceptable risk profile.

What does it mean for the wider property market?

If additional finance translates into more developments starting construction, the longer-term effect could be an increase in housing supply.

More supply can help improve choice for buyers and support local housing markets.

However, funding is only one part of the development process.

Planning decisions, construction costs, labour availability, material prices, infrastructure and buyer demand all affect whether a development ultimately reaches completion.

An important signal for the development sector

The expansion of the ENABLE Build facility is significant because it recognises the role smaller housebuilders play in housing delivery.

The £350 million guarantee facility is not itself a £350 million housebuilding grant.

Instead, it is a mechanism intended to encourage additional lending.

The key measure of success will therefore be how much additional development finance reaches viable projects and, ultimately, how many homes are delivered.

For smaller developers operating in a difficult financing environment, the expansion could provide additional room to move projects from planning and acquisition into construction.
