The government’s drive toward net zero by 2050 is changing how properties are assessed for energy efficiency - and landlords need to prepare. The minimum EPC rating to let a property is set to rise from E to C by 2028 for new tenancies, and by 2030 for existing tenancies.
At Rocket Property Management, we’re already reviewing the proposed changes so our landlords stay ahead without overspending.
Here’s what you need to know.
The EPC System Is Changing - And It’s Bigger Than You Think
Until now, the EPC rating was mainly based on the cost of energy use. But that’s about to change.
The latest government consultation (which closed in May 2025) confirms a shift to a more holistic model that focuses on:
- Building fabric and insulation
- Energy usage and efficiency
- Carbon emissions
- Smart readiness
This means the energy performance of your property won’t just be about double glazing or bills - it’ll be about whether your home can help stabilise the UK’s national grid.
New EPC Minimum Ratings from 2028
The government’s direction of travel is now clear:
- New Tenancies: Must have an EPC of C or above from 2028
- Existing Tenancies: Must comply by 2030
If your property is currently rated D or below, action will be required.
“Smart Readiness” Will Be a Big Factor
One of the most surprising updates is the focus on smart energy usage.
Between 4pm-7pm, UK energy usage peaks - and the government wants to encourage landlords to help spread energy demand. That means:
- Installing smart meters and thermostats
- Potentially using home batteries to store off-peak energy
- Considering electric heating alternatives where heat pumps aren’t viable
These upgrades will influence your EPC rating - even if they don’t affect your insulation.
Do You Need to Upgrade Now?
Not necessarily.
Rocket is closely monitoring the government’s implementation plan. We don’t recommend spending thousands on upgrades today - because the methodology for the new EPC system is still being finalised.
Instead, we’re planning ahead:
- Reviewing government updates and consultation responses
- Liaising with EPC assessors and compliance experts
- Creating individual upgrade plans for Rocket landlords across 2026-2027
Our goal is to integrate EPC improvements into your existing property maintenance schedules - avoiding major one-off costs where possible.
What Rocket Clients Can Expect
If you’re a Rocket landlord, here’s what you need to know:
- We’ll alert you when changes directly impact your property
- We’ll help plan upgrades around other scheduled work (like gas certs or EICRs)
- We’ll ensure compliance deadlines are met without last-minute panic
- We’ll avoid unnecessary spend - and keep your property market-ready
Final Word
This isn’t just another compliance task - it’s a shift in how rental homes are valued, managed, and let. The good news? You’ve still got time and making energy improvements will help with a refinance because most mortgage lenders now offer better rates for higher EPC ratings.
Even better: you’ve got Rocket.
We’ll help you navigate the changes, protect your investment, and make the transition as smooth (and cost-effective) as possible.
