An energy price cap – a sensible response to a market imperfection?

Following concerns about the market power of the Big Six energy suppliers in the UK and high prices for gas and electricity, the industry regulator, Ofgem, referred the industry to the Competition and Markets Authority (CMA) in June 2014. The CMA published its final report in June 2016. This argued that while there was sufficient potential for competition, consumers nevertheless needed further encouragement to switch suppliers. This would strengthen competition in the market.

To encourage switching, the CMA proposed the creation of a database that would include the details of customers who have been on a supplier’s standard variable tariff (SVT) for three or more years. Competitor energy suppliers would have access to this database to offer better deals for these customers.

There had already been calls for price caps to be imposed on suppliers. For example, in the run-up to the 2015 general election, the then Labour leader, Ed Miliband, proposed imposing a price freeze. This was criticised by the Conservatives for being too anti-market, that it would encourage energy companies to raise prices prior to the freeze and that it would be of no benefit in times of falling wholesale energy prices (which was the position in 2015).

Indeed, in its 2016 report, the CMA recommended price caps only for the 16% of people on prepayment meters and these would be variable caps not freezes. This was followed in February 2017, by Ofgem’s announcement that a temporary price cap for such customers would come into effect in April 2017. The level of the cap would vary by meter type and region. It would also be reviewed every six months to reflect changes in costs and remain in place until 2020. There would be no cap on other customers.

But in the run-up to the 2017 election, the Conservatives announced that they would, after all, introduce a price cap on SVTs – 66% of customers are on such tariffs. Before the details were announced, there was much speculation as to what form such a cap would take? It would not be a simple freeze. But there was debate as to whether caps would vary with wholesale costs or whether they would be relative to the company’s lowest tariffs or to those of its rivals.

As it turned out, the proposal was for a cap on standard variable tariffs. It would be set by Ofgem and reviewed every six months. The cap would be based on the cheapest standard variable tariffs in each part of the UK, taking into account the variable costs for transporting energy there. Ofgem will adjust the cap every six months to reflect changes in the wholesale cost of energy.

Questions

  1. What scope is there for tacit collusion between the Big Six energy suppliers?
  2. What is meant by the RPI–X price cap? How does it differ from proposals being considered by the government?
  3. Why are people often reluctant to switch energy supplier?
  4. How could people be encouraged to switch supplier?
  5. What are the advantages and disadvantages of imposing a price cap for SVTs (a) relative to costs; (b) relative to lower-priced tariffs?
  6. Comment on Centrica’s chief executive officer Iain Conn’s statement that “price regulation will result in reduced competition and choice, and potentially impact customer service”.
  7. Comment on the statement by Lawrence Slade, chief executive officer of Energy UK, that intervention would create “huge uncertainty around government intentions, potentially putting at risk the billions in investment and jobs needed to renew our energy system”.
  8. Would an announcement of the introduction of a price cap in the near future necessarily encourage energy companies to raise their price now?
