Energy efficiency is at the forefront of most home owners these days, but it turns out that a newer home doesn’t always come with the certainty of a better energy rating. New research reveals that, shockingly, some newly built flats in the UK have an energy rating far below the average energy efficiency performance expected for dwellings of that type, meaning higher energy bills. A study by heating experts Boiler Central has found that the highest median Energy Performance Certificate (EPC) score for new flats is just 59.5 in North Lincolnshire, and 60 in North East Lincolnshire, which gives them both a D rating. The overall picture of energy ratings across Great Britain was much more encouraging. Out of 330 areas in England and Wales that were included in the analysis of the latest ONS figures, 261 have a highest median EPC score of 81 or above for new build flats – good enough for a B rating.

With government’s saying that gas boilers are to be phased out in order for the UK to achieve its carbon targets why does an EPC rarely recommend one? What is energy efficiency? The first point to consider is “What is energy efficiency?” When EPCs were first devised, the thought was that consumers would perceive energy efficiency as the amount of money they spent on fuel, and demonstrating savings would motivate home owners to make improvements. That is why the EPC is based on a cost-based metric, the cost of fuel (for heat, light and water) for each square meter of floor area of the home. The problem with this assumption is twofold: Research has shown that for many people saving money, either because they don’t have the money to invest or because the payback periods are not attractive, is not enough on its own. A cost metric will not help reduce carbon emissions when the cheaper fuels have higher carbon emissions. Elmhurst proposes that EPCs are restructured to give equal prominence to the property’s carbon emissions (CO2), energy consumption (kWh) and energy cost (£s) and that the methodology is updated at least every three years to reflect improvements in technology and changes in the way in which energy is produced.
