The UK Government is aware of the challenges Sri Lanka faces around water management and quality, and the unique challenges faced by communities in the Northern Province. Officials from the British High Commission Colombo regularly visit the Northern Province to meet a range of stakeholders to hear their experiences and issues. A number of public bodies in Sri Lanka, including the National Water Supply and Drainage Board, have conducted tests into the water quality. The Chunnakam Power plant has offered compensation to those affected by water pollution. The UK Government supports the International Water Management Institute, an international water management research organisation, to provide solutions to increasing water scarcity in Puttalam and Kilinochchi.

Projections of future supply of oil and gas from the UK, as used by BEIS and the Climate Change Committee, factor in assumed production from fields that have been licensed to date (including Cambo).

All development proposals for oil and gas fields with existing licences are subject to a robust regulatory process before a decision on approval is made by the Oil and Gas Authority.

The prices charged by energy providers are set by the market and are largely determined by the cost of internationally-traded electricity and gas. For default tariffs, where competition has less of an effect on price, Ofgem sets a price cap on suppliers, based on the efficient costs of supply. During its first year the default tariff price cap was estimated to have saved households £1 billion and continues to save consumers £75- £100 a year on average.

The Government sees competition as the best way of securing value and quality service for consumers. The number of domestic gas and electricity suppliers has increased from 10 in 2010 to around 50 now, and customers who switch can save up to £150 a year.
