Understanding the Energy Performance Certificate (EPC) and ‘energy-inefficient buildings’

5 min read

The Energy Performance Certificate (EPC) has become a key factor when buying, selling or renting. Here’s how to interpret it, what it really means and how to turn a constraint into an advantage.

What the Energy Performance Certificate measures

The energy performance certificate classifies a property from A (highly energy-efficient) to G (high energy consumption), based on its energy consumption and greenhouse gas emissions. It is compulsory for all sales and lettings, and its period of validity is regulated.

Properties classified as F and G are commonly referred to as ‘energy-inefficient properties’. Their status changes in line with regulations, particularly when it comes to letting them out: this is something to bear in mind, whether you are buying or selling.

Its impact on value and trading

A good energy performance certificate (EPC) provides reassurance, broadens the pool of potential buyers and helps maintain the price. Conversely, a poor EPC rating often becomes a bargaining chip and can narrow the pool of buyers, particularly investors looking to let the property.

But a poor energy performance certificate is not a foregone conclusion: if it is clearly explained, backed up by figures and accompanied by suggestions for improvements, it may even reveal potential for improvement — and therefore an opportunity for the right buyer.

Improving your manners

Insulating the loft and walls, replacing windows and doors, installing a more efficient heating system, and improving ventilation: a few well-chosen measures can improve energy efficiency by one or more energy efficiency classes. Government grants are available, depending on the work carried out and your circumstances.

Common Questions

Yes, a sale is still possible regardless of the label. It is mainly the letting of property that is gradually being subject to greater regulation. When it comes to a sale, transparency and a strong sales pitch make all the difference.
