Why this matters now for Kingston Upon Thames landlords

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

EPC Assessor Kingston Upon Thames

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 Kingston Upon Thames, where the average poor-rated rental property SAP scores just 57.3, 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, 91 rental properties in Kingston Upon Thames are below that threshold. That's 32.85% of all rental stock in the Kingston Upon Thames 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 Kingston Upon Thames, 72 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 Kingston Upon Thames landlords don’t realise the goal posts are changing before the deadline arrives.

Uncover the hidden defaults affecting your Kingston Upon Thames EPC rating

Most EPC certificates rely on "worst-case" assumptions when information is missing - and in Kingston Upon Thames, those hidden defaults are likely dragging ratings down across 364 Kingston Upon Thames 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 Kingston Upon Thames, assumed wall defaults are the most common culprit - affecting properties across Kingston upon Thames 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 flats typical of Kingston Upon Thames, 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 57.3 across the area, many properties are closer to EPC C than their certificate suggests.
