More than a third of the UK’s infrastructure – including energy, water and transport – is under foreign ownership, the competition watchdog has said.
But the Office of Fair Trading (OFT) said foreign investment can strengthen competition and help drive down costs.
Foreign ownership varies by sector, the OFT said, with rail being one of the least popular areas. Waste and airport sectors were more highly favoured by overseas companies and investors.
The OFT study aimed to map infrastructure ownership in the UK and provide reassurances to investors over competition.
The Government expects some £200 billion will be invested into the country’s infrastructure over the next five years, the OFT added.
