## Overview of New EPC Rules for Landlords

The government has announced a streamlined approach to energy efficiency requirements for private rented properties in England and Wales. From 1 October 2030, all such properties must have an EPC rating of at least C. This replaces previous phased deadlines and applies equally to new and existing tenancies. Landlords may need to invest up to £10,000 per property to meet this standard, with substantial penalties for non-compliance.

## Single 2030 Deadline Simplifies Compliance

The most significant change is the introduction of a single compliance date. Earlier proposals suggested a 2028 start for new tenancies, but now all properties must comply by 1 October 2030. While this provides landlords with more time to plan, it also signals a likely surge in demand for energy efficiency upgrades as the deadline approaches.

## Investment Cap and Financial Implications

The government has capped the maximum required investment at £10,000 per property, including VAT. However, the average expected spend is estimated at around £5,400, as many properties will not require extensive retrofits. Landlords can utilise grants such as the Warm Homes: Local Grant or ECO4 to offset costs within this cap. Notably, the Boiler Upgrade Scheme voucher of £7,500 cannot be counted towards the £10,000 limit but can be used alongside it for installing heat pumps.

Additionally, a zero rate of VAT on energy-saving materials is guaranteed until March 2027, and certain upgrades may qualify as tax-deductible repairs if they replace existing systems. Importantly, any relevant expenditure from 1 October 2025 will count towards the £10,000 cap, encouraging landlords to begin improvements early.

## Dual-Metric Standard for Compliance

The new EPC framework requires properties to meet two metrics:

– **Primary standard (fabric performance):** Landlords must first improve the building’s fabric, including insulation (cavity wall, loft, underfloor), draught-proofing, and double glazing.

– **Secondary standard (landlord’s choice):** After meeting fabric requirements or registering an exemption, landlords can choose between upgrading the heating system to low-carbon options (like heat pumps) or focusing on smart technology improvements such as solar panels, battery storage, or smart meters.

The government has clarified that landlords will not be forced to replace functioning gas boilers if the property cannot meet the smart readiness standard after reasonable efforts.

## The “Grandparent” Clause Rewards Early Action

Properties with an EPC rating of C or above under the current Energy Efficiency Rating (EER) system before 1 October 2029 will be considered compliant until the EPC expires, even if they do not meet the new dual-metric standards. Since EPCs last ten years, this could mean compliance until as late as 2038 for some landlords. However, once the EPC expires, a new-style EPC must be obtained, and the property must meet the updated standards if it falls below the required rating.

Landlords with properties rated D or below must obtain a new reformed EPC before commencing any upgrade works to ensure investments are guided by current recommendations.

## Updated Exemptions to Support Landlords

Recognising that some properties cannot feasibly achieve EPC C, the government has introduced several exemptions:

– **Affordability exemption:** For properties valued under £100,000, the investment cap is limited to 10% of the property’s value.

– **Solid wall insulation exemption:** Landlords may opt out of installing solid wall insulation if it is the only remaining fabric measure.

– **Extended validity:** Cost cap and affordability exemptions now last ten years instead of five.

– **Negative impacts exemption:** Landlords can avoid measures that would damage the building or reduce its value by more than 5%.

– **Landlord grace period:** New landlords taking over tenanted properties can register a six-month temporary exemption to arrange upgrades or gather evidence for longer exemptions.

## Increased Penalties and Enforcement

Enforcement will intensify with fines up to £30,000 per property for breaches such as letting non-compliant homes or submitting false exemption information. From late 2026, the Private Rented Sector (PRS) Database will require landlords to register themselves and their properties, enabling local authorities to cross-check compliance automatically.

Local authorities will also have expanded powers to issue compliance notices demanding up-to-date EPCs, tenancy agreements, and proof of energy improvements, prioritising properties most at risk of fuel poverty.

## What This Means for Landlords

Landlords should begin assessing their properties now to avoid costly last-minute upgrades and penalties. Early investment counts towards the £10,000 cap starting October 2025, allowing costs to be spread over time. Checking property values is also crucial, as the 10% cap for lower-value homes may significantly reduce required expenditure.

Planning ahead will help landlords meet the new dual-metric standards and navigate exemptions effectively, ensuring compliance with the 2030 deadline.
