There has been great anxiety about the possible negative impacts on the environment of this legislation. Lords amendment 40 seeks to restore site specific protections for most cases where they do not involve wider issues, such as nutrient neutrality, but it has been opposed by the Government, as we have heard. Can we trust the Government to have their heart in the right place when it comes to nature versus development? We can pick up a big clue by looking at what has been happening in my constituency in West Sussex.

For the last four years, Horsham district has been contending with the complications of water neutrality, which is often wrongly confused with nutrient neutrality. It is something that applies only to my district and a couple of neighbouring areas. It concerns possible damage to a unique wetlands habitat on the River Arun, which is home to a rare species of snail and many birds. On a precautionary basis, Natural England has required a halt to any new development that would increase demand on the water supply abstracted at nearby Hardham. Natural England was wrong to impose such a draconian limit. The “not one litre more” rule prevented small businesses from building even the smallest project, and that seriously damaged the local economy.

I do not have any confidence either in the abrupt lifting of all restrictions, as happened a fortnight ago. Southern Water promised to reduce its Hardham abstraction licence by a few million litres a day, but that will not make any difference, because it never used the whole allowance anyway—it was just a notional figure set many decades ago.

The immediate crisis for Horsham is how the changes affect planning and housing development. For the past four years, Horsham has been in the ludicrous position of having to obey two totally contradictory laws. One law says that we have to build circa 1,000 houses a year. The other law says that we cannot build any houses at all if they will use extra water. That is clearly quite a challenge. As a result, we have fallen from being an authority that exceeded our housing targets, even though they were very stiff, to being one of the worst performers in the country, with a land supply of less than one year. It is literally against the law for us to obey the law.

As a result, Horsham district council has been forced to accept a series of applications that contradict its local plan and that make complete nonsense of the strategic plan-led development that the Government always profess to support. Complications around water neutrality have prevented a new local plan from being passed, and that has prevented major new environmental provisions from coming into force.

This legal nonsense has done huge damage to Horsham district and is set to do even more. The sudden lifting of water neutrality today leaves us exposed to wholly unconstrained development, which will do major damage to our environmental ambitions. It is impossible to make meaningful plans for new schools, clinics and community services to support the enormous targets that we will be forced to build when speculative developments keep going through that have none of those attributes.

Do I trust the Government to have their heart in the right place when it comes to environmental protections? No, I do not. Do I believe that they are committed to plan-led development? No, I do not. The Government are content to see holes dug all across our beautiful Horsham countryside in the hope that it might dig the Chancellor out of her own personal fiscal black hole.

I therefore urge the Minister to support Lords amendment 40, and to consider how the legislation is affecting my constituency. I invite him to meet me and Horsham district council so that we can explain that what he is doing will not just sacrifice our local environment but make the delivery of affordable housing—my overall key ambition for Horsham—harder, not easier.
