Energy Efficiency

Domestic Energy Performance Certificates (EPCs) can be a useful source of information on the energy efficiency of homes. Around 9,000 assessments are lodged annually in the district as houses are sold, re-let or improvement grants and Feed-in Tariffs are applied for. An A rating is the most efficient rating and a G rating is the least. The Government’s target is that all domestic properties will have a C rating or better by 2035. There has been an increase in the most efficient ratings over the last few years (see chart below), driven by growth in housebuilding and the standards now required by building regulations. The proportion of ratings reaching only E,F or G are falling, although 2016 saw an increase in response to a spurt of home-improvement activity through Energy Company Obligation schemes. These schemes have targeted the hardest-to-treat properties and homes in low income areas and on benefits. Just under 12,600 measures were delivered between 2013 and September 2018.

A broader analysis of the local private housing stock showed that the average SimpleSAP (another energy efficiency measure) rating for all private sector dwellings in Wakefield is 58, which is better than both England and Yorkshire and The Humber. Despite this relatively good performance, however, the analysis shows that still only 23% of private housing stock has levels of loft insulation that would meet the latest recommendations (at least 25cm of rock wool).

Renewable Energy Generation

To date, the rate of domestic photovoltaic (PV – solar panel) installations in Wakefield has been higher than the West Yorkshire and England averages. At the end of 2018 there were 5,434 domestic PV installations on the Feed-in Tariff Register, giving a combined capacity of 17.9 MW. Non-domestic installations account for a further 3.8 MW.

In 2017, a total of 123,200 MWh of electricity was generated in Wakefield district from renewable sources (excluding energy from incinerating municipal solid waste). Around 17% of this renewable generation was from solar, while the largest contribution was from burning plant biomass (see chart opposite). The capacity for generation rose threefold as the new Ferrybridge Multifuel 1 plant became fully operational in July 2015. A second Multifuel plant at Ferrybridge is under construction. A 500 kW hydro scheme started generation at Kirkthorpe, near Wakefield, in November 2016 and second 500 kW hydro project on the River Aire near Knottingley started generation in September 2017.
