So much for the idea that the woes of the water sector, and Thames Water in particular, would kill investors’ appetite for all British infrastructure assets. Here comes National Grid, which will probably be the UK’s biggest-spending infrastructure company over the next decade, with a mammoth fundraising that would not be possible if the stink from Thames had infected everything in the vicinity.
National Grid’s near-£7bn rights issue, to back a five-year, £60bn spending programme in the UK and US, is the biggest by a London-listed company since 2009. It is larger than expected and comes before the UK energy regulator, Ofgem, has nailed down the price control regime for the 2026-31 period. Throw in the supposed uncertainties created by Thames, plus a general election, and you might assume the safe option would have been to wait a while.
