Why this matters now for Brentwood landlords

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

EPC Assessor Brentwood

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 Brentwood, where the average poor-rated rental property SAP scores just 62.3, 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, 370 rental properties in Brentwood are below that threshold. That's 33.33% of all rental stock in the Brentwood 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 Brentwood, 330 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 Brentwood landlords don’t realise the goal posts are changing before the deadline arrives.

Uncover the hidden defaults affecting your Brentwood EPC rating

Most EPC certificates rely on "worst-case" assumptions when information is missing - and in Brentwood, those hidden defaults are likely dragging ratings down across 1,263 Brentwood 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 Brentwood, assumed floor defaults are the most common culprit - affecting properties across Unknown local authority 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 Brentwood, 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 62.3 across the area, many properties are closer to EPC C than their certificate suggests.

Small fixes can = big gains

330 rental homes in Brentwood are rated EPC D - just a handful of points from compliance. With our real-time interactive EPC analysis, we show you exactly how upgrades or evidence submissions can move your score, with instant results before you spend a penny.

Landlord EPC questions for Brentwood

370 rental properties in Brentwood are currently rated below EPC C (bands D–G), representing 33.33% of the latest EPC records in Unknown local authority.

From 1 October 2030, all privately rented properties in England including those in Brentwood must achieve a minimum EPC rating of C to be legally let. Fines of up to £30,000 per property apply for non-compliance. There is a £10,000 cost cap per property on required improvements.

Currently yes — EPC D properties in Brentwood can still be legally let. However from 1 October 2030 the minimum standard rises to EPC C. In Brentwood, 330 properties are rated EPC D and are only a few points from compliance, meaning many could reach EPC C through low-cost evidence or minor upgrades.

For houses typical of Brentwood, the cheapest route is usually to address assumed defaults first — 1,263 properties in Brentwood 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. Common low-cost wins include loft insulation certificates, glazing records, and heating control verification.

Most EPC certificates use worst-case assumptions when an assessor cannot verify insulation or heating controls. In Brentwood, 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.

Assumed defaults are worst-case values applied by EPC software when an assessor cannot verify a property's insulation, construction, or heating controls. They are one of the most common reasons EPC ratings are lower than they should be. In Brentwood, 1,263 rental properties are currently affected by assumed defaults — meaning their true performance may be better than their certificate suggests.

The Home Energy Model (HEM) is replacing the current RdSAP 10 EPC methodology from late 2026. Properties are likely to score lower under HEM, making EPC C harder and more expensive to achieve. In Brentwood, where the average poor-rated property scores 62.3, the gap will be harder to close under the new methodology. Landlords who achieve EPC C under today's rules will hold that rating for 10 years, protecting them from stricter future requirements.

Yes — EPC exemptions are available to landlords in Brentwood in specific circumstances. These include a cost cap exemption (if you have spent up to £10,000 and still cannot reach EPC C), a third-party consent exemption (where a freeholder or planning authority refuses permission), and a property devaluation exemption (if improvements would reduce the property's value by more than 5%). Exemptions must be registered on the PRS Exemptions Register and are valid for up to 10 years. Read our full EPC exemptions guide →

Based on the latest EPC records, the postcodes in Brentwood with the highest concentration of below-EPC-C rental properties include CM14 4YF, CM14 4UE, CM4 9AJ. Properties in these postcodes are statistically more likely to be affected by assumed defaults or to benefit from targeted low-cost upgrades.

The average EPC efficiency score for poorly rated rental properties in Brentwood is 62.3. EPC C begins at a score of 69, meaning the average below-C property in Brentwood needs to gain approximately 7 points to reach compliance.
