For a summary of all the EPC changes, including the 2030 rules for landlords and a key-dates table, see our guide to EPC changes explained.

The government is introducing a new system called the Home Energy Model (HEM), which will eventually replace the current RdSAP methodology used for domestic EPCs.

So what does this actually mean for you as a homeowner or landlord? Will EPC ratings change? What about MEES rules? And will electric-heated homes finally be treated more fairly?

Here’s a plain-English breakdown from a domestic EPC assessor’s perspective.

What Is the Home Energy Model (HEM)?

The Home Energy Model (HEM) is the government’s new way of calculating EPCs for domestic dwellings in England and Wales.

It will eventually replace RdSAP, which has been used for years but is widely considered outdated.

Why the change?

The current EPC system:

• Uses simplified assumptions
• Heavily favours gas heating
• Struggles to fairly assess modern low-carbon homes

HEM is designed to:

• Be more accurate
• Better reflect real-world energy performance
• Support the UK’s move towards low-carbon heating

How EPCs Will Change Under HEM

No longer just one A–G rating

Under the new system, EPCs won’t rely on a single overall score alone. Instead, homes will be assessed using multiple headline metrics, likely including:

• Fabric efficiency – how well insulated the building is
• Heating system performance – efficiency and carbon impact
• Energy costs – predicted running costs
• Smart readiness – ability to use smart controls, storage, EV charging etc.

This gives a clearer and fairer picture of how a home actually performs.

For example:

A well-insulated home with electric heating may score strongly on fabric, even if the heating system itself needs improvement.

Will This Affect Existing EPCs?

Not immediately.

• Current EPCs remain valid until they expire (10 years)
• HEM-based EPCs are expected to roll out from late 2027
• There will likely be a transition period where both systems exist

If you need an EPC now for:

• Selling a property
• Renting a property
• MEES compliance

The current EPC system still applies

What Does This Mean for MEES (Minimum Energy Efficiency Standards)?

At present:

• Rental properties must meet EPC E or above
• There are proposals to raise this to C in future

Under HEM:

• MEES may no longer rely on a single EPC letter
• Compliance could depend on specific metrics, such as fabric efficiency or heating system performance

This could mean:

• A landlord might pass on insulation but fail on heating
• Targeted upgrades rather than “chasing a letter”

⚠️ Important:
The exact MEES rules under HEM are not final yet, but change is coming.

Will Electric-Heated Homes Be Rated More Fairly?

This is one of the biggest changes.

Under the current EPC system:

• Electric heating often scores poorly
• Gas boilers are heavily favoured
• Even efficient electric systems can look bad on paper

Under HEM:

• Low-carbon heating (like heat pumps) is expected to score better
• Heating systems will be judged more on carbon impact, not just fuel cost
• Fossil fuel systems may be capped in how high they can score

This means:
✅ Heat pumps should rate more fairly
✅ Well-insulated electric homes won’t be automatically penalised
⚠️ Old direct electric heating without controls or storage may still score lower

So yes — the model is deliberately shifting away from gas-favouritism.

How Will This Affect EPC Assessments in Canterbury?

For homeowners and landlords in Canterbury, Whitstable, Herne Bay, Faversham and nearby towns, this means:

• EPCs will become more informative
• Upgrade advice will be more specific
• Fabric improvements (insulation, glazing, airtightness) will matter more
• Heating choices will have long-term EPC implications

From an assessor’s point of view, EPCs will:

• Use better data
• Rely less on blanket assumptions
• Provide clearer upgrade pathways

What Should Homeowners & Landlords Do Now?

You don’t need to panic — but it is smart to plan ahead.

Good future-proof upgrades include:

• Loft and wall insulation
• Draught-proofing
• Efficient heating controls
• Preparing for low-carbon heating
• Improving overall fabric before changing heating

These improvements will benefit EPCs both now and under HEM.

This guide focuses on how landlords in Kent can realistically plan their route to EPC C.

Why EPC C isn’t the same for every property

Kent’s rental housing stock is varied. We regularly assess:

• Victorian terraces in Canterbury and Ramsgate
• 1930s semis in Whitstable and Herne Bay
• Flats and HMOs in Dover and Folkestone
• Newer rental homes around Ashford and Thanet

Because EPC ratings are based on modelled energy costs, not just insulation thickness or boiler age, the same upgrade can have very different results depending on the property.

This is why there’s no single checklist that guarantees an EPC C.

The mistake many landlords make

A common approach we see is landlords being told to:

• “Just change the boiler”
• “Add solar panels”
• “Install a heat pump”

Without checking whether those upgrades will actually move the EPC rating.

In some cases, expensive improvements result in little or no EPC gain, because the measures weren’t prioritised correctly.

Our approach: draft EPCs and tailored guidance

Instead of guessing, our approach is to model the outcome first.

We do this by producing a draft EPC, which allows us to:

• Test different improvement combinations
• See which measures genuinely raise the EPC score
• Identify the most cost-effective route to EPC C

Draft EPCs for landlords in Kent

This approach is especially useful for:

• Properties currently rated D or E
• Older or harder-to-treat homes
• Landlords with multiple properties
• Planning upgrades over several years before 2030

Typical improvements that help reach EPC C (Kent properties)

While every property is different, the following measures commonly improve EPC ratings when correctly applied:

1. Heating system efficiency

Older boilers are still common in Kent rentals. Upgrading to a modern, efficient system can help — but only when combined with appropriate controls.

2. Insulation upgrades

• Loft insulation
• Cavity wall insulation (where suitable)
• Floor insulation in some ground-floor properties

Insulation often provides some of the most reliable EPC gains, especially in older homes.

3. Heating controls

Simple improvements like:

• Programmable thermostats
• TRVs
• Smart controls

can make a measurable difference to EPC scoring at relatively low cost.

4. Lighting

Upgrading to low-energy lighting throughout the property is usually straightforward and contributes incremental EPC improvements.

5. Solar panels (where appropriate)

Solar PV can significantly improve EPC ratings in the right circumstances — particularly for electrically heated properties — but roof suitability and orientation matter.

Why timing matters for landlords

Although the EPC C deadline is 2030, waiting carries risks:

• Installer demand may increase closer to the deadline
• Costs may rise
• Some upgrades require tenant cooperation
• Non-compliant properties may become harder to let

From our experience across Kent, landlords who plan early have more options and better outcomes.

Start with clarity, not guesswork

If you’re a landlord in Kent, the most effective first step isn’t installing anything — it’s understanding your starting point.

A current EPC, combined with a draft EPC model, gives you:

• A clear picture of where the property stands
• A realistic pathway to EPC C
• Confidence that any upgrades will actually count

Final word

Improving an EPC rating to C doesn’t need to be rushed or expensive — but it does need to be planned properly.

From our perspective as a local Kent EPC assessor, the landlords who get the best results are those who take a measured, informed approach based on real data, not assumptions.

That’s exactly what EPCs — and draft EPCs in particular — are designed to support.

From 2030, landlords will need to ensure their rental properties meet a minimum EPC rating of C, replacing the current EPC E requirement under MEES regulations.

Although 2030 may sound distant, many landlords across Canterbury, Deal, Dover, Margate and Ashford are already asking what this means in practice.

What is changing?

At the moment:

• Rental properties must meet EPC E or above

From 2030:

• Minimum standard increases to EPC C

This applies to most privately rented homes and will affect both new and existing tenancies.

What this means for landlords in Kent

Much of Kent’s rental stock is older housing. In our EPC assessments, we commonly see rental properties sitting at:

• EPC D
• EPC E

Often due to:

• Older boilers
• Limited insulation
• Electric heating without solar
• Single glazing

Moving from E or D to C usually requires planned improvements, not just a single upgrade.

EPC ratings and heating upgrades

One important point landlords should understand is how EPCs are currently calculated.

EPCs are based on modelled running costs, not just energy efficiency. This means some low-carbon upgrades — such as heat pumps — don’t always increase EPC ratings as much as expected under the current system.

Because of this, the most reliable ways to improve EPC ratings often include:

• Insulation upgrades
• Efficient heating systems
• Modern heating controls
• Low-energy lighting

A professional landlord EPC assessment in Kent will show which measures actually move the rating.

Why acting early makes sense

Leaving EPC upgrades until closer to 2030 carries risks:

• Installer availability may tighten
• Upgrade costs could rise
• Some work requires tenant coordination
• Non-compliant properties may become harder to let

From a business point of view, EPC C properties are more resilient to future regulation and more attractive to tenants concerned about energy bills.

Our advice as a local EPC assessor

If you’re a landlord in Kent, the smartest step right now is understanding where your property stands.

A current EPC gives you:

• Your actual rating
• A list of recommended improvements
• A realistic pathway towards EPC C

Most people aren’t asking about politics — they’re asking simple, practical things:
Will this actually help reduce my bills?
Do I qualify?
Does my house even suit a heat pump or solar panels?

As a local EPC assessor working in Kent, this article explains what the new funding means in real terms for everyday homes, and where Energy Performance Certificates fit into the picture.

What is the Warm Homes Plan?

The Warm Homes Plan is a long-term government programme that will provide funding for home energy upgrades over the next five years. The focus is on:

• Air source heat pumps
• Solar panels
• Home battery storage

Funding will be delivered through a mix of grants and low-interest loans, with additional support for lower-income households.

One key element is the extension of the Boiler Upgrade Scheme, which continues to offer grants of up to £7,500 towards an air source heat pump.

For many households, this doesn’t cover the full cost — but it does make upgrades more achievable than they were a few years ago.

What we’re seeing in Kent homes

Kent has a wide mix of property types, and that matters.

We regularly assess:

• Older terraces in Canterbury and Ramsgate
• 1930s semis in Whitstable, Herne Bay and Dover
• Newer estates around Ashford and Thanet

Some homes are well suited to solar panels straight away. Others need insulation or heating improvements first before a heat pump makes sense.

This is why a proper EPC assessment in Kent is important. An EPC doesn’t just give a rating — it shows:

• Where energy is being lost
• Which upgrades will improve efficiency
• How changes may affect running costs and EPC score

Will heat pumps and solar panels reduce bills?

They can — but it depends on the property.

A heat pump on its own doesn’t guarantee lower bills, especially with current electricity prices. Where we’ve seen the best outcomes locally is when:

• Solar panels help offset electricity use
• The home has decent insulation
• Heating systems are properly sized and controlled

This is why the Warm Homes Plan encourages a combination of technologies rather than a single upgrade.

Why EPCs matter for grants and upgrades

Many energy efficiency grants already require a valid EPC, and future schemes are likely to rely on EPC data even more.

If you’re considering:

• Heat pump grants in Kent
• Solar panel funding
• Energy efficiency improvements

Having an up-to-date EPC puts you in a much better position.

A local, practical takeaway

Not every home needs a heat pump right now. Not every roof suits solar panels. The sensible first step is understanding your property.

From our experience across Kent, homeowners who start with an EPC avoid costly mistakes and plan upgrades that actually work.
