Energy Assessment

Watt-NRG can arrange for a fully qualified Energy Assessor to visit both domestic and commercial properties to carry out an energy assessment in order to produce an Energy Performance Certificate providing you with the information you need to improve the energy efficiency of your property.

This service is free for customers purchasing a Solar PV system!

The Department of Energy & Climate Change (DECC) has put in place a minimum energy efficiency requirement for anyone wanting to install Solar PV panels on their building and claim the full FIT rate. From 1st April 2012, properties will be required to produce an Energy Performance Certificate (EPC) rating of ‘D’ or above to qualify for the full FIT rates. It is estimated that around half of all properties are already eligible for a ‘D’ rating.

Energy Performance Certificates provide the following:

  • Information on your property's energy use and typical energy costs.
  • A recommendation report with suggestions to reduce energy use and save money.
  • Details of the person who carried out the EPC assessment.
  • Who to contact if you want to make a complaint.

EPC's carry ratings that compare the current energy efficiency and estimated costs of energy use with potential figures that your home could achieve. Potential figures are calculated by estimating what the energy efficiency and energy costs could be if energy saving measures were put in place.

The rating measures the energy efficiency of your home using a grade from ‘A’ to ‘G’. An ‘A’ rating is the most efficient, while ‘G’ is the least efficient. The average efficiency grade to date is 'D'. All homes are measured using the same calculations, so you can compare the energy efficiency of different properties.

Energy Performance Report

EPC's also provide a detailed recommendation report showing how you could reduce the amount of energy you use and your carbon dioxide emissions. The report lists:

  • Suggested improvements, like fitting loft insulation.
  • Possible cost savings per year, if the improvements are made.
  • How the recommendations would change the energy efficiency rating of the property.
  • Which improvements may be eligible for funding through the Green Deal.

You don’t have to act on the recommendations in the recommendation report. However, if you decide to do so, it could make your property more attractive for sale or rent by making it more energy efficient.

Watt-NRG did a great job on our installation; they were prompt, tidy and efficient. After a year, the installation is out-performing the generation promises with no problems. Very pleased.
