The UK continues to be a global leader in cutting greenhouse gas emissions, according to Ofgem’s annual State of the Market report, but progress is slowing.
Greenhouse gas emissions have fallen by 42% since 1990, more than any other large advanced economy, due largely to the decarbonisation of electricity generation. This has been driven by Government policies, such as the carbon price which penalises coal plants in particular, and the huge growth in wind and solar power. In fact, renewables generated a record 33% of our electricity last year.
Progress is slowing however, with last year seeing the smallest reduction in emissions since 2012 (2.5% this year, down from a 3% fall the previous year).
Transport continued to be the largest single source of carbon emissions, although emissions fell slightly last year (3%), partly down to an increase in the number of alternative fuel vehicles, which now account for 2% of the licenced cars on the road in GB.
In June, the Government passed legislation requiring the UK to reduce carbon emissions to net zero by 2050 following calls from the Committee on Climate Change (CCC). To meet this target, significant investment is required, particularly in renewables, as well as policies aiding the roll-out of new low carbon technologies and supporting innovation to decarbonise how we heat our homes and businesses.
A priority of Ofgem’s new corporate strategy is helping decarbonise the economy at the lowest cost to consumers. Ofgem will set out more details on this early next year.
Separately, competition in Great Britain’s retail energy market continued to develop in 2018-19. Medium suppliers benefitted the most from record switching rates (just over 20% in June 2019, up from 19% the previous year), which swelled their market share by 7 percentage points in electricity and 5 percentage points in gas to over 20% of consumers overall.
They also gained customers who were transferred to them under Ofgem’s safety net after a number of smaller suppliers failed and exited the market.
At the same time, the market dominance of the six larger suppliers continued to weaken as they lost 1.3 million customers and saw market share fall to around 70% of consumers, compared to around 75% the year before. Small suppliers for the first time saw their market share fall to 9% of consumers, down from 10% the year before.
During this period, when shopping around for new deals, more consumers turned to price comparison websites (49%), ‘auto-scanning’ notifications (8%) and auto-switching (2%).
Meanwhile, the number of consumers who said they’d never switched fell to 29% - down from 34% in 2018.
In January Ofgem implemented a cap on the price of default tariffs to protect consumers from overpaying for their energy.
The majority of customers on these deals are with the six larger suppliers who charged at the upper limit of the cap. In contrast, medium and small suppliers priced at £43 and £78 below the cap (January – June 2019).
Price transparency has improved in general for business customers. However microbusinesses still lose out and pay on average twice as much for gas and 30% more for electricity than the average across all business customer segments, often because they are on expensive default tariffs.
