New EPC Rental Benchmarks “Unlikely to Succeed”, Says NRLA

Why It Matters

The shortfall in qualified assessors threatens compliance timelines, potentially delaying the private rented sector’s contribution to the UK’s carbon‑reduction agenda and increasing costs for landlords.

Key Takeaways

• New EPC C rating required by 2030 for rentals
• NRLA warns assessor shortage could stall compliance
• Training gap may create bottleneck for retrofitting professionals
• Government support needed to upskill assessors quickly
• Failure could delay energy‑efficiency improvements in private sector

Pulse Analysis

The Energy Performance Certificate (EPC) system has become a cornerstone of the UK’s climate strategy, linking property standards directly to carbon‑reduction targets. By 2030, every rental dwelling in England and Wales must reach at least a C rating, a move intended to push landlords toward deeper energy‑efficiency upgrades. While the policy aligns with national net‑zero ambitions, its success hinges on a functional supply chain of qualified assessors who can certify improvements and verify compliance.

The National Residential Landlords Association (NRLA) has sounded the alarm that the market lacks sufficient trained EPC assessors and retrofitting specialists to meet the accelerated timeline. According to NRLA, the current pool of professionals is already stretched thin, and the mandatory retraining required for the new C‑rating methodology could create a severe bottleneck. This shortage risks delaying assessments, inflating costs for landlords, and ultimately undermining the intended environmental benefits. The association urges the government to fund accelerated training programs and streamline certification pathways before the October 2030 deadline.

If the skills gap remains unaddressed, the private rented sector may fall short of the EPC targets, eroding confidence in the regulatory framework and slowing progress toward the UK’s broader energy‑efficiency agenda. Proactive government intervention—such as subsidies for assessor training, partnerships with trade schools, and clear guidance on retrofitting standards—could mitigate supply‑chain pressures and ensure a smoother rollout. Successfully navigating these challenges would not only protect landlords from unexpected compliance costs but also accelerate the decarbonisation of millions of homes, delivering both economic and environmental dividends.
