For more than a decade, the Energy Company Obligation (ECO) scheme has supported a significant part of the UK’s domestic energy efficiency sector. Through the programme, millions of homes have received insulation, heating upgrades and other improvements designed to reduce energy bills and tackle fuel poverty.

While the scheme has delivered clear benefits for households, it has also created a substantial supply chain of installers, contractors and specialist service providers. Many of these businesses have relied heavily on ECO-funded projects to generate revenue.

As the current phase of the scheme approaches its conclusion, the outlook for some companies operating in this sector is becoming uncertain. For a number of Eco Suppliers, the loss of ECO-funded work may place serious pressure on cash flow. If new sources of income cannot be secured quickly enough, some businesses may find themselves facing insolvency and potentially liquidation.

At Business Rescue Expert, we regularly advise directors whose businesses are experiencing sudden changes in market conditions or the loss of key revenue streams. Understanding how the end of the ECO scheme could affect the sector is therefore important for suppliers operating within the retrofit and energy efficiency market.

What Is the ECO4 Scheme?

The Energy Company Obligation is a government-backed programme designed to improve the energy efficiency of homes while reducing fuel poverty across Great Britain.

The current phase of the scheme, known as ECO4, began in 2022 and operates across England, Scotland and Wales. It is funded through obligations placed on the UK’s largest energy suppliers, who must finance energy-saving improvements for eligible households.

The scheme focuses primarily on properties with poor energy performance ratings and households that may struggle with energy costs. Typical improvements delivered through ECO programmes include:

  • Loft and cavity wall insulation
  • External wall insulation
  • Replacement boilers and heating systems
  • Other home energy efficiency measures

Since the introduction of ECO in 2013, government data shows that millions of energy efficiency improvements have been installed in more than two million homes across Great Britain. The scale of the programme has supported a large network of contractors and specialist installers.

For many businesses working in this sector, ECO-funded work has become the core of their operations.

Why the End of ECO4 Matters for Eco Suppliers

Unlike traditional construction projects, ECO installations have historically been funded through energy suppliers rather than direct payments from homeowners. This structure has created a relatively reliable pipeline of work for contractors involved in delivering the scheme.

As a result, many Eco Suppliers expanded their businesses in order to meet demand. This often involved significant investment in operational capacity, including:

  • Recruitment of installation teams
  • Vehicles and specialist installation equipment
  • Accreditation and compliance requirements
  • Surveying and retrofit coordination services

While this expansion was justified when the scheme was delivering consistent work, the end of ECO4 will gradually reduce the availability of funded installations. For companies that depend heavily on this work, the change may create a sudden gap in revenue.

Financial Pressures Across the Retrofit Sector

As ECO4 approaches its conclusion, some suppliers are already experiencing a tightening pipeline of projects. Competition for remaining contracts is increasing and future demand is less certain.

Many companies in the sector have fixed costs that cannot easily be reduced in the short term. These may include:

  • wages for trained installation teams
  • vehicle finance and fleet costs
  • warehouse leases and storage facilities
  • ongoing compliance and accreditation fees

If installation volumes fall significantly, these overheads can quickly begin to place strain on cash flow.

In addition, the sector has faced increased scrutiny in recent years following concerns about the quality of some installations delivered under earlier insulation schemes. Investigations have highlighted cases where large numbers of installations required remedial work, creating additional financial pressure for some contractors.

For businesses already operating with tight margins, these challenges can increase the risk of financial distress.

When the Loss of ECO Work Leads to Insolvency

When a company loses a key revenue stream, financial problems can escalate quickly. For Eco Suppliers, early warning signs of financial distress may include:

  • difficulty paying suppliers on time
  • mounting HMRC arrears
  • reliance on short-term borrowing
  • delays in paying staff wages
  • increasing pressure from creditors

If a company is unable to pay its debts as they fall due, it may be considered insolvent.

At this point, directors should seek professional advice as soon as possible. When insolvency becomes likely, directors’ legal duties shift towards protecting the interests of creditors rather than shareholders.

Options for Eco Suppliers Facing Liquidation

The appropriate course of action will depend on the financial position of the business and whether there is a viable future outside of ECO-funded work.

Where a company still has potential to trade successfully, restructuring options may be available.

A Company Voluntary Arrangement (CVA) can allow a business to repay its debts over time while continuing to operate. You can read more about this option here:

If the company requires immediate protection from creditor action while a rescue plan is developed, Administration may be considered. Further information is available here:

However, where the business is no longer viable following the loss of ECO income, directors may need to consider Creditors’ Voluntary Liquidation (CVL). This allows the company to close in a structured and legally compliant way while ensuring creditors are treated fairly. More information can be found here:

Seeking Advice Early Can Make a Significant Difference

The end of the ECO4 scheme is likely to represent a major transition for parts of the UK energy efficiency sector. While many companies will adapt by diversifying into other areas of retrofit or construction work, others may find that the loss of ECO-funded installations leaves their business model unsustainable.

For Eco Suppliers experiencing a sudden reduction in work, obtaining professional advice early can make a significant difference. Understanding the available options can help directors protect their position and avoid financial problems escalating unnecessarily.

At Business Rescue Expert, our licensed insolvency practitioners provide confidential advice to company directors facing financial difficulties. Whether a business can be rescued through restructuring or requires an orderly liquidation, early guidance can help ensure the situation is handled responsibly and in accordance with directors’ legal duties.

Frequently Asked Questions

What happens to Eco Suppliers when the ECO4 scheme ends?

When the ECO4 scheme ends, the amount of funded energy efficiency work available to installers and contractors is likely to reduce significantly. Businesses that rely heavily on ECO-funded projects may experience a sharp decline in revenue.

For some Eco Suppliers this may simply require a shift towards private retrofit work or other construction projects. However, companies that expanded their operations specifically to deliver ECO installations may find it more difficult to replace that income quickly.

If revenue falls below the level required to cover operating costs, the business could face financial distress.

Can Eco Suppliers go into liquidation if work stops?

Yes. If an Eco Supplier loses a large portion of its revenue following the end of the scheme and cannot replace that work, the company may become insolvent.

This could occur if the business is unable to:

  • pay suppliers and subcontractors
  • meet payroll obligations
  • keep up with HMRC tax liabilities
  • service finance agreements or loans

Where a company is no longer financially viable, directors may need to consider Creditors’ Voluntary Liquidation as a way to close the business in a structured and compliant manner.

What should Eco Suppliers do if their business is struggling?

If your business is experiencing financial pressure due to a reduction in ECO-related work, it is important to seek professional advice as early as possible.

Early guidance can help directors understand whether the business can be rescued through restructuring or whether a formal insolvency procedure is required.

Possible options may include:

  • restructuring debts through a Company Voluntary Arrangement
  • entering Administration to protect the business from creditor action
  • placing the company into Creditors’ Voluntary Liquidation if it is no longer viable

Speaking with a licensed insolvency practitioner can help you assess the situation and decide on the most appropriate course of action.

Do directors risk personal liability if their company becomes insolvent?

Directors do not automatically become personally liable if their company becomes insolvent. However, once a company is unable to pay its debts, directors must prioritise the interests of creditors.

Continuing to trade while the company has no realistic prospect of avoiding insolvency can create legal risks. Seeking early professional advice can help directors ensure they comply with their legal duties.
