The UK property market is currently undergoing a significant shift toward energy efficiency, making it vital for property owners to understand their funding options. For many in the rental sector, the Warm Homes Plan offers a pathway to upgrading inefficient buildings and protecting future rental income.

TL;DR: Landlords can use the Warm Homes Plan (WHP) to access grants and support for insulation and low-carbon heating, helping properties reach a minimum EPC rating of C. While some upgrades are subsidised, any additional financing carries risks, and your property may be at risk if repayments are not made.

I’m a Landlord; how do I use the WHP to improve my EPC rating?

As the UK government moves toward more stringent environmental standards, landlords are increasingly looking for ways to future-proof their investments. The Warm Homes Plan (WHP) is a central pillar of the current strategy to decarbonise UK housing. By understanding how to navigate this scheme, you may be able to significantly improve your property’s Energy Performance Certificate (EPC) rating while potentially reducing the long-term maintenance costs associated with damp and inefficient heating.

What is the Warm Homes Plan?

The Warm Homes Plan is a comprehensive government initiative designed to upgrade millions of homes across the UK. It focuses on a “fabric first” approach, which means prioritising the external and internal structure of a building—such as insulation and windows—before moving on to high-tech heating systems like heat pumps. For a landlord, the WHP is a gateway to several different funding streams, including the Home Upgrade Grant (HUG) and the Boiler Upgrade Scheme.

The plan aims to ensure that as many homes as possible reach an EPC rating of C or above by 2030. For the private rented sector, this is particularly relevant, as high-energy-efficiency homes are often more attractive to tenants who are struggling with rising utility bills. A better EPC rating can also enhance the capital value of your property and make it easier to secure competitive mortgage rates in the future.

Understanding the Importance of EPC Ratings

An Energy Performance Certificate (EPC) provides a detailed breakdown of a property’s energy efficiency, rated from A (most efficient) to G (least efficient). Currently, most private rented properties in the UK must have a minimum rating of E to be legally let. However, policy trends suggest that a move to a minimum rating of C is likely in the coming years. If you are asking “I’m a landlord; how do I use the WHP to improve my EPC rating?”, you are already taking a proactive step toward regulatory compliance.

Improving an EPC rating is not just about ticking a box; it involves a series of calculated upgrades. The WHP provides the framework to identify which measures—such as solid wall insulation, loft insulation, or floor insulation—will provide the biggest jump in your rating for the lowest relative cost.

How to Access Support Under the WHP

To use the Warm Homes Plan effectively, you first need to determine your eligibility. While many grants are focused on low-income homeowners, several branches of the plan are accessible to landlords, especially if your tenants meet certain income criteria or if the property is located in a specific “deprived” postcode. Here is a typical process for a landlord looking to engage with the scheme:

• Check Local Authority Participation: Many components of the WHP are delivered through local councils. You should contact your local authority to see if they are currently running a Home Upgrade Grant (HUG) phase.
• Verify Tenant Eligibility: Some grants require the tenant to be receiving certain benefits. In these cases, you may need to work closely with your tenants to complete the application.
• Professional Assessment: Most schemes will provide a free or subsidised energy assessment. A qualified assessor will visit the property and produce a report detailing which measures will most effectively improve the EPC rating.
• Approved Installers: To receive funding, you must typically use TrustMark-registered installers. The WHP ensures that the work meets high standards, protecting your investment.

Common Upgrades Funded by the WHP

The WHP generally covers a range of measures that can move a property from a D or E rating up to a C. These measures are often categorised into “insulation” and “clean heat.”

Insulation and Draught Proofing

This is usually the first step. Cavity wall insulation, loft insulation (up to the recommended 270mm thickness), and underfloor insulation can significantly reduce heat loss. For older properties with solid walls, internal or external wall insulation may be available, though these are more invasive and expensive. Draught-proofing windows and doors is a low-cost measure that frequently appears in WHP recommendations.

Low-Carbon Heating

Once the property is well-insulated, the WHP encourages the transition from gas boilers to air source or ground source heat pumps. The Boiler Upgrade Scheme, often linked with the wider Warm Homes Plan goals, may provide a substantial grant toward the cost of a heat pump, making it much more affordable for landlords to swap out aging, inefficient boilers.

Financing the Gap: Bridging and Other Options

While the WHP provides significant support, it may not cover 100% of the costs for every property, especially if you own a large portfolio or a complex older building. In these instances, landlords often look to private financing to bridge the gap between the grant and the total cost of works.

Many landlords utilise bridging loans to fund property improvements quickly. Bridging loans are short-term financial products designed to “bridge” a gap until long-term financing or a property sale is arranged. There are two main types: open and closed.

• Closed Bridging Loans: These have a fixed repayment date, usually based on a specific event, such as the completion of a property sale.
• Open Bridging Loans: These have no fixed repayment date but are typically expected to be repaid within 12 to 18 months.

It is important to note that most bridging loans use “rolled-up” interest. This means you do not usually make monthly payments; instead, the interest accumulates and is paid in one lump sum at the end of the term. This can help with cash flow during the renovation period, but it means the total debt grows over time.

Your property may be at risk if repayments are not made. Failing to repay a loan secured against your property could lead to legal action, repossession, increased interest rates, and additional charges. Always ensure you have a clear “exit strategy”—a plan for how you will repay the loan—before proceeding.

The Benefits of a “C” Rated Property

Using the WHP to hit a C rating offers several practical advantages beyond simple legal compliance. Properties with higher EPC ratings generally experience fewer issues with condensation and mould, which are common causes of tenant complaints and property damage. Furthermore, many “green” mortgage products are only available for properties with a rating of C or better, offering lower interest rates that could save you thousands over the lifetime of a loan.

People also asked

What is the minimum EPC for landlords in 2025?

Currently, the legal minimum EPC rating for private rented properties in England and Wales is E. While there have been proposals to raise this to C by 2025, the government has adjusted timelines, though a target of 2030 remains a major focus for future policy.

Can I get a grant for a heat pump as a landlord?

Yes, the Boiler Upgrade Scheme (BUS) is available to many landlords. It typically provides a grant of £7,500 toward the cost of an air source or ground source heat pump, provided the property meets certain insulation standards.

Does the Warm Homes Plan cover double glazing?

The WHP may cover double glazing or window repairs, but it is often prioritised lower than loft or wall insulation. Funding for windows is usually only granted if the current glazing is exceptionally poor and other “fabric” measures have already been addressed.

Is the Warm Homes Plan the same as ECO4?

The Warm Homes Plan is a broader strategy that encompasses various schemes, whereas ECO4 is a specific obligation placed on energy companies to provide efficiency measures to low-income and vulnerable households.

How much does it cost to move from EPC D to C?

The cost varies significantly based on the property type, but many landlords spend between £5,000 and £15,000. Using grants from the Warm Homes Plan can often reduce this out-of-pocket expense significantly.

Final Considerations for Landlords

Improving the energy efficiency of your rental portfolio is a complex but necessary task. By asking “I’m a landlord; how do I use the WHP to improve my EPC rating?”, you are engaging with the tools available to make this transition more affordable. While the initial process of applying for grants and managing contractors can be time-consuming, the long-term benefits—increased property value, lower maintenance, and happier tenants—are often worth the effort.

Always conduct thorough research into any financial product you use to supplement grant funding. Ensure that the measures you choose are the ones recommended by a professional assessor to guarantee the best possible improvement to your EPC rating. By taking a strategic approach, you can ensure your properties remain compliant, efficient, and profitable for years to come.
