Energy performance is now a commercial risk, not a box-tick.
If your building sits at D / E / F / G, you’re exposed: leasing constraints, compressed capex windows, and weaker positions in transactions and reporting. The direction of travel is clear — and the sites that act early control cost, disruption, and outcomes.
Where we are now (UK)
Partial government response published
Confirmed elements including what reformed EPCs will measure and when EPCs will be required.
Further response expected
Scheduled to cover DEC validity periods, EPC & DEC data, EPC quality management, AC inspection reports, and additional consultation questions.
Under review (no confirmed dates)
Proposed minimum standards often referenced in industry planning (e.g. EPC C / EPC B scenarios) remain subject to review. Plan for direction — treat dates as unconfirmed unless formally announced.
From exposure to improvement
Use the sliders or drag the markers to model a shift in EPC band. This is illustrative — every site needs assessment, but the commercial exposure is real.
Compliance pressure points
Further government update expected
Following the partial response on 21 Jan 2026, a fuller update is scheduled later in 2026 (details subject to publication).
ESOS pressure
Audit and evidence requirements become more central to upgrade planning and operational performance narratives.
Planning risk if left late
Market commentary often models an EPC C scenario — but timelines remain under review. Late action compresses capex windows.
Data bottleneck
As reporting streams converge, weak baselines and missing metering slow compliance and dilute improvement claims.
Higher uplift scenarios
EPC B is frequently referenced in planning — but remains unconfirmed. Earlier action reduces cost, disruption and retrofit complexity.
What this puts at risk
Letting restrictions
As thresholds tighten, low ratings can delay renewals, block lettings and trigger reactive spend under time pressure.
Capex compression
Leaving improvements late reduces options: higher cost, less control, more disruption — and weaker outcomes.
Asset value & liquidity
Lower-rated buildings face more scrutiny in transactions, refinancing discussions and ESG reporting.
Operational waste
DECs and operational evidence expose avoidable kWh/m² — and the cost shows up every month.
EPC vs DEC
Asset Rating
EPCs are the compliance trigger for many letting decisions. They reflect the asset model and specification assumptions.
- Required: sale, letting, renewal, construction
- Valid: typically 10 years
- Commercial link: MEES thresholds apply to many non-domestic rentals
Operational Rating
DECs reflect actual energy consumption. Reform direction points toward stronger data, clearer metrics and digital records.
- Commonly applies: qualifying public buildings
- Valid: typically 1 year
- Value: highlights operational inefficiency and improvement opportunity
Risk flags to track
How EMC improves outcomes
Baseline & exposure mapping
Assess current position, constraints and performance levers across the estate.
Operational optimisation first
Reduce waste and stabilise systems before capex-heavy upgrades.
Targeted engineered interventions
Deploy the right measures to shift measurable performance drivers.
Evidence-ready reporting
Documentation aligned to compliance cycles and audit defensibility.
ACIR / TM44 (Cooling inspections)
Important — but secondary to EPC/DEC in terms of minimum thresholds. Track TM44 as part of the wider compliance ecosystem and integrate findings into upgrade planning.
