Key Takeaways

• Proposed timeline: New tenancies will require EPC C from 2025, all tenancies from 2028. The government is consulting on exact dates, but preparation should start now.
• Cost cap increased to £10,000 – Landlords will need to spend up to this amount per property to reach C; if impossible, an exemption may be available.
• Property value impact – Homes rated C or above are already selling for 3–5% more than D‑rated equivalents and attract better tenants.
• Action plan: 1) Check current EPC, 2) Get a retrofit assessment, 3) Prioritise cost‑effective improvements, 4) Budget for upgrades before 2025.
• Exemptions remain – If reaching C would cost more than £10,000 or cause devaluation, you can register an exemption (valid for 5 years).

Introduction – The Clock Is Ticking

A landlord in Manchester recently sold a Victorian terrace for £15,000 less than identical properties on the same street. The reason? His EPC was a D, while the others were C. The buyer factored in the £8,000 upgrade cost and negotiated accordingly.

The EPC C 2025 deadline isn’t just another regulation – it’s a financial reality that will affect your property’s value, rentability, and running costs.

Originally proposed in the 2021 Energy White Paper, the government’s plan is clear: all new tenancies from 2025 must have an EPC rating of C or above. By 2028, that applies to all existing tenancies.

This article cuts through the confusion. I’ll explain the latest proposed timelines, what you should do right now, and how to avoid being caught out when the rules change.

1. The Proposed Timeline – From E to C

The current minimum is an E rating. The next step is C. Here’s the expected phased introduction:

| Date | Requirement |

|——|————-|

| 2025 (proposed) | All new tenancies must have an EPC rating of C or above. |

| 2028 (proposed) | All tenancies (including existing) must have an EPC rating of C or above. |

| 2030 (under discussion) | Potential increase to EPC B for new tenancies. |

Important: These dates are still subject to consultation. The government has delayed the original 2025 deadline for existing tenancies to 2028, but new tenancies from 2025 are still expected to need a C.

Why the Delay?

In 2023, the government acknowledged that many landlords needed more time and clarity. The 2028 deadline for existing tenancies gives a longer runway, but the 2025 deadline for new tenancies remains a firm target.

What this means for you: If you plan to re‑let a property in 2025 or later, it must be at least a C. If you have a sitting tenant, you have until 2028 to upgrade.

2. What Does “EPC C” Actually Mean?

An EPC C rating corresponds to a SAP score of 69–80. SAP (Standard Assessment Procedure) is the methodology used to calculate energy efficiency.

Typical properties that achieve C:

• Modern homes (built after 2000) with good insulation and efficient heating.
• Older properties that have been retrofitted with double glazing, loft insulation, cavity‑wall insulation, and a condensing boiler.
• Well‑maintained mid‑terrace houses with some energy‑saving features.

Properties likely to struggle:

• Victorian/Edwardian solid‑wall homes with single glazing.
• Flats in older blocks with no cavity walls.
• Properties with electric storage heaters or old non‑condensing boilers.

How to Check Your Current Rating

1. Find your EPC at [www.gov.uk/find-energy-certificate](https://www.gov.uk/find-energy-certificate).

2. Look at the SAP score – it’s on page 2 of the certificate.

3. See the recommendations – the EPC will list improvements needed to reach a higher band.

If your property is already D or above, reaching C may be relatively straightforward. If it’s E or below, you’ll need more extensive work.

3. The £10,000 Cost Cap – What You’ll Need to Spend

Under the proposed regulations, landlords will be required to spend up to £10,000 per property (including VAT) to improve it to a C rating.

How the Cap Works

• You must implement all “relevant improvements” that can be installed within the £10,000 budget.
• Improvements are considered in order of cost‑effectiveness (cheapest first).
• If after spending £10,000 the property still isn’t a C, you can register a “high‑cost” exemption.

Example: A 3‑bed semi‑detached house currently rated D. Recommended improvements:

• Loft insulation to 300mm (£400)
• Cavity‑wall insulation (£600)
• Upgrade boiler to A‑rated condensing (£2,500)
• Double glazing (if single‑glazed) (£4,000)
• Solar panels (optional) (£5,000)

Total cost without solar: £7,500 – within the cap. With solar: £12,500 – exceeds cap, so solar could be omitted if not required to reach C.

What Counts Towards the Cap?

• Materials and labour for energy‑efficiency improvements.
• VAT.
• Costs of any necessary surveys or reports.
• Not included: Cosmetic works, repairs unrelated to energy efficiency, furniture, appliances.

4. Impact on Property Value – The C Premium

Homes with a better EPC rating are already commanding a price premium. According to research by Rightmove (2023):

• Properties rated C sell for 3.5% more than equivalent D‑rated homes.
• Rental properties rated C achieve 2–4% higher rents and have lower void periods.
• Mortgage lenders are increasingly offering better rates for energy‑efficient homes (green mortgages).

Why? Tenants and buyers are more energy‑cost conscious. A C‑rated home typically has lower utility bills, better comfort, and future‑proofs against regulatory changes.

Case study: A landlord in Birmingham upgraded a 2‑bed flat from D to C for £3,200 (new boiler, loft insulation, LED lighting). The property’s value increased by £8,000, and she was able to raise the rent by £50 per month. The investment paid for itself in under 5 years.

5. What Landlords Should Do Now – A 4‑Step Action Plan

Don’t wait until 2025. Follow this plan to stay ahead:

Step 1: Assess Your Current Position

• Check the EPC for every property in your portfolio.
• Note the current rating and SAP score.
• Identify which properties are D or below – these are your priority.

Step 2: Get a Retrofit Assessment

For properties rated D or below, consider a retrofit assessment (cost: £200–£400). This is more detailed than a standard EPC and provides a tailored roadmap to reach C, including:

• Which improvements give the biggest SAP point gain.
• Precise cost estimates.
• Phasing recommendations (what to do now vs later).

Step 3: Prioritise Cost‑Effective Improvements

Focus on “quick wins” that deliver the most SAP points per pound:

1. LED lighting – Replace all bulbs (cost: £50–£150, SAP gain: 1–3 points).

2. Draught‑proofing – Seal windows, doors, loft hatch (cost: £100–£300, SAP gain: 2–5 points).

3. Loft insulation – Top up to 300mm (cost: £300–£500, SAP gain: 5–10 points).

4. Heating controls – Install smart thermostat (cost: £150–£300, SAP gain: 3–6 points).

5. Cavity‑wall insulation – If suitable (cost: £500–£800, SAP gain: 10–15 points).

Step 4: Budget and Schedule

• Create a upgrade budget for each property.
• Schedule works during void periods or tenant turnover.
• Consider financing options (green mortgages, landlord energy grants, etc.).

6. Exemptions – When You Can’t Reach C

Even with the £10,000 cap, some properties may not be able to reach C due to:

• Technical constraints – solid walls, listed‑building restrictions, lack of space for insulation.
• High cost – improvements would exceed £10,000.
• Devaluation – works would reduce property value by 5% or more (requires RICS report).
• Consent refused – tenant, freeholder, or planning authority refuses permission.

If you believe you qualify, you must register an exemption on the PRS Exemptions Register. Exemptions last 5 years, after which you must re‑assess.

Warning: Don’t assume you’re exempt without evidence. The burden of proof is on you, and failing to register correctly can lead to fines.
