EPC UPGRADE SERVICE
Energy Performance Certificate (EPC) Upgrade Service
An Energy Performance Certificate (EPC) is a legal requirement for nearly all properties in the UK when they are built, sold, or rented. It rates a building’s energy efficiency from A (most efficient) to G (least). With energy bills rising and regulations tightening, improving your EPC rating is no longer a ‘nice to have’—it’s often essential. For landlords, domestic property owners, and commercial investors alike, an EPC upgrade is now a critical part of staying compliant and maintaining property value.
Whether you need to meet the Minimum Energy Efficiency Standard (MEES) or want to reduce long-term costs, EPC upgrades are a practical investment with both financial and legal benefits.
What is an EPC Upgrade?
An EPC upgrade involves improving a building’s energy efficiency to achieve a better EPC rating. This is usually done by acting on the recommendations listed in the EPC report, such as upgrading insulation, installing an efficient heating system, or improving windows and lighting.
The process starts with an EPC assessment, carried out by a qualified EPC assessor. They’ll examine the condition of the property and use government software to calculate its energy efficiency. After upgrades, an updated assessment should be done to confirm the new EPC rating—especially if the goal is EPC certificate renewal or meeting landlord EPC requirements.
Properties that don’t meet the minimum EPC rating of E cannot legally be let unless an official EPC exemption is in place. Most of these exemptions are temporary and require strong evidence, so they shouldn’t be relied upon as a long-term solution.
Why Energy Retrofit Assessments Matter for Property Owners
The most immediate reason for EPC rating improvement is compliance. Under MEES, landlords must ensure their rental properties in England and Wales meet the minimum energy efficiency standard. Letting a property with an F or G rating is unlawful unless it’s formally exempt. Penalties for non-compliance can reach £5,000.
But compliance isn’t the only concern. Domestic EPC upgrades also support improved tenant satisfaction and lower running costs. A more efficient home is easier to heat, more comfortable to live in, and increasingly in demand. For landlords, this helps with tenant retention and makes void periods shorter.
Upgrading now also helps prepare for future changes in legislation. Government proposals suggest the minimum EPC rating for rental properties will increase to C by 2028. Acting early gives property owners time to plan and spread out EPC upgrade costs, rather than scrambling later when demand for qualified installers increases.
On the financial side, a higher EPC rating can boost property valuation and improve mortgage terms—particularly for buy-to-let investors. Surveyors and lenders are already factoring in energy efficiency when making decisions. From compliance to commercial benefit, upgrading your EPC makes good business sense.

Common Methods Used in EPC Retrofit Improvements
Most EPC upgrades involve a mix of practical changes that reduce heat loss and improve energy usage.
Insulation upgrades are among the most cost-effective. Loft insulation is quick to install and cuts down on heat escaping through the roof. Cavity wall and underfloor insulation are also widely used in domestic and rental properties to meet minimum energy efficiency standards.
Heating system upgrades are another key area. Replacing an old boiler with a modern condensing unit can significantly increase a property’s EPC score. In some cases, heat pumps may be a better option—especially where long-term efficiency is the goal.
Efficient lighting installation is a low-cost improvement that has a direct impact on the EPC rating. Swapping out older bulbs for LED lighting across the property is a simple, effective step.
Double or triple glazing upgrades also contribute to better thermal efficiency. Older windows are often a weak spot, and replacing them can lead to both improved comfort and an uplift in your EPC score.
In some cases, renewable energy options such as solar panels may also be considered, depending on budget and property type. These systems reduce reliance on the grid and support longer-term EPC compliance.
Benefits of Upgrading Your EPC Rating
A better EPC rating brings a range of tangible benefits. First, you’ll likely see a reduction in energy bills. This is true for homeowners, landlords, and tenants alike—efficient homes cost less to run.
Second, an improved EPC rating can increase the property’s market value. Buyers and investors are more conscious of energy performance, especially as legislation tightens and energy prices remain volatile.
For rental properties, better EPC ratings help attract tenants who are looking to save on bills and live in more comfortable homes. Rental property energy efficiency is becoming a key selling point in competitive markets.
Upgrading also helps avoid future disruption. Meeting current standards today can prevent larger costs and legal issues down the line. If the government does raise the minimum rating to C in the coming years, properties already upgraded will avoid the rush and be better placed for resale or re-letting.
Where applicable, some landlords and homeowners can access government grants for EPC improvements. Schemes like the Boiler Upgrade Scheme help reduce the cost of installing low-carbon heating systems. These cost-effective energy improvements make compliance more accessible while improving long-term energy efficiency.

Regulations and Legal Responsibilities
For landlords, EPC regulations are clear: all rental properties must have an EPC rating of E or above to be legally let. This applies to both domestic and commercial premises. Properties that don’t meet this standard must be improved or registered for a valid EPC exemption.
MEES regulations are part of broader UK energy efficiency legislation designed to reduce carbon emissions and make housing stock more sustainable. Non-compliance can result in enforcement action, including fines and restrictions on letting the property.
There are a few scenarios where exemptions may apply, such as listed buildings, properties where improvement costs exceed £3,500 (for domestic rentals), or where consent is refused for upgrade works. But even these must be formally registered and are reviewed regularly.
EPC compliance also matters in commercial settings. Poor ratings can limit rental opportunities, reduce asset value, and complicate lease negotiations. EPC upgrades are therefore becoming part of routine property planning across all sectors.
