What Does SAP Ratings Mean For You?

SAP Ratings The energy used in homes today are responsible for 18% of the carbon dioxide emitted into the air in the UK with an additional 15% of emissions coming from electricity used in buildings. With such a large impact, caution and efficient improvements have become a priority for many property owners due to government implemented regulations, such as the Standard Assessment Procedure (SAP) and Energy Performance Certificate (EPC). As heating and water tend to use the most amount of energy in a property, it should be a priority for an owner to choose the most efficient and cost-effective option.

SAP has been adopted by the government as part of the UK national methodology for energy performance of buildings. It has a fundamental role in driving energy savings in households as it underpins regulations that drive carbon savings and bill reductions. SAP calculates the environmental impact rating, the dwelling emission rate, and the target emission rate.

Below is a summary comparing electric heating with associated costs and ratings in an efficient home versus a non-efficient home:

For new homes, the main requirement is to meet a carbon emissions target for the building as a whole to stay compliant (reducing emissions from the household sector by 3.7% every year from 2008). A property’s SAP rating is calculated in units of kg CO2/m2/year which cannot exceed the target emission rate corresponding to the shape and size of the house. Factors such as insulation and window glazing, can have a significant impact on your overall heating efficiency and costs, which in turn effects your SAP rating. So, minimising your CO2 emissions through household changes will have a noticeable impact on your yearly costs, as well as, compliancy.

These requirements support the efficiency of electric radiators. They are environmentally friendly as no energy is wasted due to 100% of the energy used being converted to heat. Also, no fuel is burnt during use, boosting safety, making it impossible to produce dangerous emissions such as carbon monoxide.

Year on year, choosing to use electric radiators can produce many advantages, not only for yearly costs but also when trying to stay compliant. Haverland has a wide variety of radiators to choose from for any room. Discover what will be the best choice for you – Find Your Electric Radiator
