This is Ofwat’s business plan for 2016-17 to 2020-21. This plan sets out our overall approach for delivering our strategy, ‘Trust in water’, over the next five years. We continually review what we do to make sure we are delivering the right things in an efficient way. And we update our business plan every year so that we always look five years ahead. Our plan may change significantly from year to year, as circumstances change and our priorities evolve. So our work in 2017-18 to 2020-21 should be used as an indication only. It is based our current best estimates and assumptions.
