Why This Matters

Energy Costs Are Now a Major Factor in Property Value

Following the energy crisis of 2021–22, buyers and tenants have become acutely aware of running costs. A property rated G can cost over £3,500 more per year to run than an equivalent A-rated property. Over a 10-year ownership period, that difference exceeds £35,000 - more than the cost of a comprehensive retrofit.

EPC ratings are also becoming a hard commercial constraint. Since April 2020, landlords cannot legally let residential properties rated F or G. Proposed legislation to raise the minimum to C for new tenancies (and eventually all tenancies) represents a significant financial liability for landlords with poorly rated stock.

For buyers considering a purchase with mortgage finance, a poor EPC rating can affect lending decisions, insurance costs, and - if the property is leasehold - whether service charge disputes about communal energy improvements may arise in future.

What HouseDossier Checks

Full EPC Data Plus Grant Eligibility

We query the MHCLG national EPC register for the current and historical certificates, then layer on grant eligibility and improvement cost analysis.

Current EPC Rating & Score

The current SAP score (1–100) and letter rating (A–G), plus the potential rating if all recommended improvements are made. Includes the lodgement date and the expiry date of the certificate.

Estimated Energy Running Costs

Annual estimated costs for space heating, water heating and lighting based on the EPC assessment - split by fuel type. A clear picture of what the property will cost to run at current energy prices.

Improvement Recommendations

All improvement measures listed on the EPC with estimated cost ranges and projected savings. Ranked by cost-effectiveness. Helps you prioritise what to negotiate on, or what to budget for post-purchase.

Grant Eligibility Check

Based on the EPC rating and local authority, we flag applicable government grant schemes: Great British Insulation Scheme, Boiler Upgrade Scheme, ECO4, and local authority flex funds. Thousands of pounds may be available.

Also included in the Full Dossier

  • Historical EPC certificates (all previous lodgements)
  • Comparison to neighbouring properties' ratings
  • Solar PV potential (PVGIS data for the roof location)
  • Heat pump suitability assessment
  • Wall type, roof type and insulation specification
  • CO₂ emissions figure (kg/m² per year)

How It Works

Your EPC Report in Three Steps

01

Enter the property address or postcode

We identify the property by UPRN and search the MHCLG EPC register for all certificates lodged for that address - including any expired certificates from previous lodgements.

02

We retrieve the full EPC data

The complete EPC record is retrieved: SAP score, letter rating, all improvement recommendations with costs and savings, energy cost estimates, wall/roof/window specifications, and heating system details.

03

Grant eligibility is assessed automatically

We cross-reference the EPC rating with the local authority and deprivation indices to flag any grant schemes the property is likely to qualify for. No separate application needed to see what you might be entitled to.

Important for Landlords

Since April 2020, landlords cannot create new tenancies (or renew existing ones) for properties with an EPC rating of F or G in England and Wales. From April 2023, this applies to all continuing tenancies. Properties rated E or above are currently compliant. The government has proposed raising the minimum to EPC C for new tenancies - check our Buy-to-Let Property Report for landlord-specific analysis.

FAQ

EPC Ratings - Frequently Asked Questions

How long is an EPC certificate valid for?
An Energy Performance Certificate is valid for 10 years. Once a certificate has been lodged on the national EPC register, it can be used for any subsequent sale or letting within that period. A new EPC is only required if the existing one has expired or if significant energy efficiency improvements have been made and you want to record the improved rating.
Is an EPC required when selling or renting a property?
Yes. An EPC is a legal requirement when marketing a property for sale or to let in England and Wales. For rental properties, since April 2020 all new tenancies must have an EPC rating of E or above - landlords cannot let properties rated F or G without a valid exemption. The government has consulted on raising the minimum to C for new tenancies by 2025, though the precise timescale continues to be reviewed.
What is the difference between the current and potential EPC rating?
The current rating reflects the property's energy performance as assessed, taking into account insulation levels, heating system type, windows, and other factors. The potential rating is what the property could achieve if all the recommended improvements listed on the certificate were implemented. A large gap between current and potential represents an opportunity - but also an investment cost.
Can a bad EPC rating affect my mortgage offer?
Increasingly, yes. Some lenders have begun tiering mortgage rates based on EPC ratings, offering better rates for properties rated A or B. From a valuation perspective, a poor EPC rating can affect a surveyor's assessment of maintenance costs and running costs, which can feed into valuation decisions. For buy-to-let mortgages, an EPC below E may result in a lender declining the application altogether.
What grants are available to improve an EPC rating?
Several government schemes exist. The Great British Insulation Scheme offers free or subsidised loft and cavity wall insulation for homes rated D or below, targeting fuel-poor households. The Boiler Upgrade Scheme provides £7,500 towards a heat pump. ECO4 (Energy Company Obligation) provides upgrades to low-income households. Our Full Dossier flags specific grants the property is likely to qualify for based on current EPC rating, council tax band, and deprivation data.
My property does not have an EPC - is that normal?
Properties built before 2008 may not have an EPC if they have not been sold or let since the EPC regulations came into force. Listed buildings are generally exempt from requiring an EPC (as energy efficiency improvements may conflict with conservation requirements). Some very recent new builds may have a certificate pending. Our report clearly notes where no EPC exists and explains why.
How is the EPC rating calculated?
EPC assessors use a government-approved methodology called the Standard Assessment Procedure (SAP). This rates a property on a scale of 1 to 100 (100 being the most efficient) and assigns an A to G letter rating. The assessment considers wall insulation, loft insulation, window glazing, heating system efficiency, water heating, and lighting. The assessment is carried out by an accredited Domestic Energy Assessor (DEA) and the results are lodged on the MHCLG national EPC register.
