Westminster Hall is an alternative Chamber for MPs to hold debates, named after the adjoining Westminster Hall.

Each debate is chaired by an MP from the Panel of Chairs, rather than the Speaker or Deputy Speaker. A Government Minister will give the final speech, and no votes may be called on the debate topic.

Hawkhurst parish council and Southern Water recently came to see me to complain about a number of developers in my constituency who have mixed surface run-off with foul water, which is illegal. Does my hon. Friend agree that, although we of course need big housing developments, if developers are proven to have illegally mixed surface run-off and foul water when building them, they should have to make good what they did?

Unquestionably, and a slightly more sympathetic approach should be taken to historical instances in which householders’ surface water drains have been connected to foul water systems, which they may not even realise. For developments that have been built since that law, it is absolutely unquestionable that developers should do that.

Finally, we must consider seriously the impact of man-made climate change on flooding. When we place responsibilities on developers, we must make sure that new developments do not deal just with the floods of the past or those of today, but with the worst floods that are yet to come. Henry Cator is chair of the Norfolk Strategic Flooding Alliance, which my constituency neighbour, the hon. Member for Mid Norfolk, mentioned. His voice is given deserved reverence in Norfolk when speaking about these issues, and he has said that climate change will create a new level of extremes that we must be ready for. Simply planning for the current levels will be wasted in years to come.

I look forward to working with hon. Members on both sides of the House on this issue. It needs proper cross-functional work from the Government if we are to ensure that the much-needed homes of tomorrow are built sustainably and that the circumstances of the communities that those houses will serve and join are protected and improved.
