Why this matters now for North Norfolk landlords

Two changes are coming — and together, they make timing critical.

The rules are getting harder

The current EPC system (RdSAP 10) is being replaced by the Home Energy Model (HEM), rolling out late 2026. The same property is likely to score lower under HEM — making EPC C harder and much more expensive to achieve. In North Norfolk, where the average poor-rated rental property SAP scores just 55.7, that gap will be even harder to close under the new methodology.

The law arrives in 2030

From 2030, rental properties below EPC C may not be legally let - putting rental income at risk. Right now, 358 rental properties in North Norfolk are below that threshold. That's 54.99% of all rental stock in the North Norfolk area that could become unlettable without action.

Act now and secure your grandfather rights

Achieve EPC C under today's rules and your rating is typically valid for 10 years - meaning you lock in compliance before the methodology changes. In North Norfolk, 223 properties are rated EPC D and are just a few points away. Many could get there through evidence alone, without major retrofit work.

Lock In Now

Get to EPC C now before it gets harder → keep that rating for 10 years → avoid stricter future requirements.

Most North Norfolk landlords don’t realise the goal posts are changing before the deadline arrives.

Lock in your EPC rating under today’s rules

Energy Performance Certificates (EPCs) are currently assessed using the RdSAP 10 methodology. If your property achieves an EPC C rating today, that certificate is valid for 10 years from the date of issue.

During this period, your property may continue to be assessed against the standards in place at the time the certificate was issued — even if future methodologies change. This is often referred to as “Grandfather Rights”.

What is changing?

The UK government is developing a new assessment framework called the Home Energy Model (HEM), which is expected to replace RdSAP from around 2027.

HEM is designed to be more detailed and data-driven, using additional property inputs and more advanced modelling. While this should improve accuracy, it may also make achieving certain EPC ratings — including EPC C — more technically demanding.

Early indications suggest that some properties could require more comprehensive upgrades, improved evidence, or higher-performing systems to achieve the same rating under HEM.

Why timing matters

Achieving EPC C under current rules may require fewer or lower-cost improvements
Your EPC certificate is valid for 10 years once issued
Future methodology changes may increase the level of detail and evidence required
Some upgrade pathways may become more complex or expensive over time

What this means for landlords

If your property can reach EPC C today, securing that rating now could help you plan ahead with greater certainty. It may also reduce the likelihood of needing more extensive upgrades in the near future if assessment standards become stricter.

While future policy and enforcement may evolve, acting earlier gives you more flexibility and control over how and when improvements are made.

In simple terms:
Reach EPC C under today’s rules → keep that rating for up to 10 years → reduce the risk of stricter and more costly requirements later.

Uncover the hidden defaults affecting your North Norfolk EPC rating

Most EPC certificates rely on "worst-case" assumptions when information is missing - and in North Norfolk, those hidden defaults are likely dragging ratings down across 911 North Norfolk rental properties right now

Defaults penalise your score

When an assessor cannot verify insulation or specific heating controls, the software defaults to the lowest possible performance. In North Norfolk, assumed floor defaults are the most common culprit - affecting properties across North Norfolk and silently pulling scores below the EPC C threshold. We identify exactly where these assumptions are reducing your rating.

Evidence can help your rating

For houses typical of North Norfolk, proving what's already there - loft insulation, glazing records, heating controls - can significantly improve your EPC score without spending anything on physical upgrades. With an average poor EPC score of 55.7 across the area, many properties are closer to EPC C than their certificate suggests.

For houses typical of North Norfolk, the cheapest route is usually to address assumed defaults first — 911 properties in North Norfolk are affected by assumed floor defaults. Providing evidence of existing insulation or heating controls costs little and can improve the EPC score without physical work.

Most EPC certificates use worst-case assumptions when an assessor cannot verify insulation or heating controls. In North Norfolk, assumed floor defaults are the most common cause of artificially low ratings. These assumed defaults can significantly reduce your score even if your property is well insulated. Providing evidence to the assessor — such as installer certificates or photos — can improve the rating without any physical upgrades.

They are one of the most common reasons EPC ratings are lower than they should be. In North Norfolk, 911 rental properties are currently affected by assumed defaults — meaning their true performance may be better than their certificate suggests.
