Energy Performance Certificates: What They Are and Why They Matter

Energy Performance Certificates (EPCs) are an essential part of property ownership in the UK. As energy costs continue to rise, understanding the importance of your property's energy efficiency has never been more crucial. Let's explore everything you need to know about EPCs.

What is an Energy Performance Certificate?

An EPC is an official document that rates a property's energy efficiency on a scale from A (most efficient) to G (least efficient). The certificate provides detailed information about a property's energy use, typical energy costs, and recommendations for improvements. Valid for 10 years from the date of issue, an EPC gives potential buyers or tenants a clear picture of how energy efficient a property is.

Legal Requirements for EPCs

Since 2008, it's been a legal requirement to have a valid EPC when:

  • Selling a property
  • Renting out a property
  • Building a new property

You must order an EPC for potential buyers and tenants before marketing your property for sale or rent. Failure to provide an EPC when required can result in a fixed penalty charge of £200 – an unnecessary expense that property owners can easily avoid.

For landlords, it's worth noting that it's now illegal to rent a property with an EPC rating below E, ensuring tenants aren't living in properties that are excessively expensive to heat.

What Information Does an EPC Contain?

A typical EPC includes:

1. Energy Efficiency Rating

Your property's current rating (A-G) and potential rating if recommendations are implemented.

2. Estimated Energy Costs

A breakdown of the estimated energy costs for lighting, heating, and hot water over a three-year period.

3. Top Recommendations

Cost-effective improvements that could enhance your property's energy efficiency.

4. Heat Demand

Information about your home's heat demand – particularly relevant in the cooler northern climate.

5. Property Details

Basic information about the property assessed, including its type, size, and construction.

Why EPCs Matter for Homeowners

Increased Property Value

Properties with higher EPC ratings typically command better prices in the property market. With energy efficiency becoming increasingly important to buyers, a good EPC rating can be a significant selling point.

Substantial Cost Savings

Implementing recommendations from your EPC can lead to significant savings on energy bills.

Environmental Benefits

By improving your home's energy efficiency, you're reducing carbon emissions and contributing to a greener future.

Future-Proofing Your Property

As environmental regulations tighten, properties with poor energy efficiency ratings may face increasing restrictions. Improving your EPC rating now helps future-proof your investment.

How to Get an EPC

Only accredited domestic energy assessors can produce valid EPCs. The assessment typically takes between 45 minutes and an hour, depending on the size of your property. The assessor will examine key elements including:

  • Windows and glazing
  • Insulation levels in lofts, walls, and floors
  • Heating systems and controls
  • Ventilation systems
  • Lighting fixtures

At Heatwiser, our 15 years of experience in the heating and electrical industry gives us a unique understanding of how these systems contribute to a property's overall energy efficiency. While we don't provide EPCs directly, our Gas Safe registered engineers and NICEIC certified team can help implement the recommendations made in your EPC.

Cost of an EPC

The cost of obtaining an EPC typically ranges from £60 to £120, depending on:

  • Your property type and size
  • Number of bedrooms
  • Location
  • The assessor's individual fees

It's worth getting multiple quotes from accredited assessors to find the best deal. Remember, the cost of an EPC is significantly less than the potential £200 penalty for not having one when required.

Improving Your EPC Rating

Common recommendations for improving EPC ratings include:

Heating System Upgrades

Replacing an old, inefficient boiler with a new A-rated system can significantly improve your energy efficiency. As Worcester Bosch accredited and Baxi approved installers, Heatwiser can advise on the most efficient heating systems for your home.

Insulation Improvements

  • Loft insulation
  • Cavity wall insulation
  • Solid wall insulation
  • Floor insulation

Renewable Energy Solutions

Installing renewable technologies like heat pumps or solar panels can dramatically improve your EPC rating. Heatwiser specialises in heat pump installations throughout the North of England.

Draught-Proofing

Sealing gaps around windows, doors, and other areas where heat can escape.

Lighting Upgrades

Switching to energy-efficient LED bulbs throughout your property.

EPCs for Landlords

If you're a landlord, it's particularly important to understand EPC requirements:

  • Since April 2018, rental properties must have a minimum EPC rating of E
  • Tenants can request consent for energy efficiency improvements
  • Penalties for non-compliance can be substantial

Our team at Heatwiser can help landlords ensure their rental properties meet or exceed the minimum standards, potentially increasing rental value while reducing tenant energy costs.
