Energy Efficiency Ratings: Everything You Need to Know

Understanding the energy efficiency of a domestic or commercial property is one of the most important factors if you want to enjoy lower bills over time and increase the value of your property. This is also critical in terms of protecting the environment and lowering the carbon footprint of a structure. The easiest way to determine if any changes need to be made is to obtain an energy efficiency rating. This comes in the form of an Energy Performance Certificate (EPC). Let’s take a look at how a building will be rated as well as what the process involves. This will help you to make an informed decision when speaking with one of our team members at Installers UK.

What is the Intention of an EPC Certificate?

An energy efficiency rating is essentially designed to highlight any factors that might be contributing to higher carbon footprint, electricity and/or heating costs. An evaluation will look at several variables including:

  • The type of insulation found throughout a structure.
  • The age and efficiency of any appliances.
  • The presence of double-or triple-glazed windows.
  • Heating systems.
  • Lighting fixtures and their associated controls.

By identifying these improvements, it is much easier to take a proactive approach when making the recommended changes.

A Look at EPC Rating Calculations

After one of these EPC surveys has been completed, you will be provided with a summary of the findings. To make it easier to understand how your property has done, the ratings are graded from “A” (extremely efficient) to “G” (major upgrades or replacements required).

An EPC certificate may be needed in a number of circumstances. For instance, landlords who are renting out their property are required to have this evaluation and adhere to the Minimum Energy Efficiency Standards otherwise known as MEES for short. A recently completed construction or renovation project might also mean that an newer, more up-to-date EPC is required. Some listed historic buildings might be exempt due to the fact that major modifications are not possible.

Installing recommended energy saving measures like cavity wall insulation, loft insulation or an upgrade to a newer boiler system can all help to increase the value and desirability of your property.

How to Improve an EPC Rating ?

There are several ways in which you can improve a poor energy efficiency rating. Assuming that a qualified EPC assessor has provided you with specific details, these can normally be addressed on an individual basis. Here are some examples:

  • Installing cavity wall insulation within your home if required.
  • Improving the level of loft insulation within your home.
  • Replacing an outdated or otherwise inefficient boiler.
  • Installing double-glazed windows.
  • Utilising modern and energy-efficient appliances.

It is important to mention that many homeowners may qualify for government grant schemes. This will save you a great deal of money if improvements and services are needed. The first step is to speak with one of our qualified technicians at Installers UK. We will be more than happy to set up a consultation at your convenience. The amount of money that can be saved from a long-term perspective is certainly worth this assessment, so we look forward to hearing from you.
