Water Supply and Housing Targets: West Kent

Debate between Tom Tugendhat and Jim Shannon

Tuesday 24th March 2026 Westminster Hall

[Tom Tugendhat (Tonbridge) (Con)]

I beg to move,

That this House has considered water supply and housing targets in west Kent.

It is a pleasure to serve under your chairmanship, Sir John—not for the first time or, I certainly hope, the last. What is less pleasurable is having no water coming out of your taps. Sadly, that could be the reality for more than 13,000 new homes in Tonbridge and Malling if the Government get their way. Planning decisions in the community are, I think we would all agree, best left to local councillors. After all, it is right that those elected at the most local level have responsibility for shaping the place they live in and represent. However, this Government’s planning policies are taking us away from that principle.

Since the general election, we have seen mandatory housing targets reintroduced and increased enormously. They are up by 34% in Tonbridge and Malling and by 63% in Sevenoaks district. Then, of course, there is the grey-belt policy. I have been getting used to Green party and Labour MPs going through the voting Lobbies and making things easier for development to merge towns and villages and create one single, homogeneous, blended whole and for development on previously protected grey-belt land. However, water seems not to have been considered. There are many aspects of water locally that I could focus on, including the excellent work done in Edenbridge on water quality by NEDRA—the New Edenbridge District Residents’ Association—but in the interests of time, I will focus my comments today on water supply only.

This is now a very salient issue for those of us in west Kent. Although Tunbridge Wells has been the worst affected, towns and villages such as Tonbridge, Edenbridge and across the north downs have lost water supply this winter and last winter. Why is that? It is because there is not enough water in the system to supply houses in our area. I am aware that the Water Industry Act 1991 in effect places a legal requirement on water suppliers to ensure that running water appears when the tap is turned on. Although South East Water is not very good at doing that right now, we also need to focus on the future. That means asking fundamental questions. Where is the water—now and in the future? Do housing targets accurately reflect the water infrastructure in west Kent?

I will focus on two authorities in the area that I represent: Tonbridge and Malling borough council and Sevenoaks district council. I emphasise to the Minister that they are two of the very best run councils in the whole country and have been for a number of years. We are very lucky to have brilliant people at both councils, and both are trying to do the right thing for future development and adopt a local plan. In both cases, however, that has been delayed from 2024 because of the Government changing planning policy. It is not the fault of either council that they do not have an adopted local plan; that is because of tinkering and meddling by the Government and, historically, the Planning Inspectorate.

[Jim Shannon (Strangford) (DUP)]

I commend the right hon. Gentleman for bringing forward this issue; he is absolutely right. He outlines a case in his own constituency, which is very pertinent to him. Unfortunately, what he describes is the case across the whole of the United Kingdom. In Northern Ireland, I have the very same problem. Northern Ireland Water seems to be discouraging planned housing, as it cannot meet the need. Does the right hon. Gentleman agree that the Government must step in with direct action and fund the deficit while enforcing the obligations on water companies to hold up their end of the deal?

[Tom Tugendhat]

It is no surprise to me that this issue applies across the whole of the United Kingdom. I very much welcome the hon. Gentleman’s intervention.

One thing that the Government have not changed, but ought to change, is the position of water companies in planning. Somewhat strangely, water companies are statutory consultees on the local plan process, but not on planning applications. I invite the Minister in her response to explain whether she agrees that this is peculiar.

There are four water supply companies across Sevenoaks district. Two cover the area that I am privileged to represent: SES Water in and around Edenbridge, and South East Water elsewhere. In advance of this debate, I asked the new leader of Sevenoaks district council, Kevin Maskell, to outline what engagement on local plan and infrastructure delivery matters the council has received from water companies. The answer was that only two of the four water companies had even replied, and the replies received were very limited. Indeed, the experience from Sevenoaks is that water companies see their role as not being a priority.

There is no detailed modelling for housing projections against water resources management plans, especially for site allocations. All infrastructure planning is deferred to the planning application stage, where the water companies are not even a statutory consultee. That makes it impossible to plan for the cumulative impact of developments on the water network. How is that good for planning? Well, it isn’t.

If the situation with water suppliers is a problem in Sevenoaks district, however, it is critically urgent and potentially disastrous in Tonbridge and Malling. For the benefit of the Minister, I will explain what has happened in recent months. Tonbridge and Malling borough council agreed to its regulation 18 local plan consultation in the autumn. It received unanimous cross-party support, which was a huge vote of confidence in the leadership of Matt Boughton and the work of Mike Taylor, the cabinet member for planning. Both of them have contributed enormously to the life of our community.

The TMBC cabinet member for infrastructure, Adem Mehmet, approached infrastructure providers for consultation responses, including South East Water, which is the drinking water supplier for almost all of the borough—and the whole of the part that I am lucky enough to represent. I have a copy of the response here, dated 17 December 2025. In it, South East Water tells Tonbridge and Malling borough council that the maximum number of additional homes it can supply between now and 2042 is 6,318. The Government housing target for the council is 19,620.

What is Tonbridge and Malling borough council expected to do? Is it supposed to allocate sites for 13,302 new homes, despite having been told that there is no infrastructure for water to be supplied to those properties? I am sure that the Minister agrees that this would not be appropriate or wise. Having received the response, and being the excellent councillor he is, Adem Mehmet wrote to South East Water on 15 January this year, which happened to be in the middle of the water outages we were facing. South East Water responded on 3 February.

Three simple questions were put to South East Water. First, does South East Water agree that it cannot provide sufficient water to cope with a significant increase in housing targets? South East Water agrees that it cannot. Secondly, do the current targets mean that there will be more water shortages? Again, South East Water agrees that the probability of water outages is higher. Thirdly, would the planned increases identified in the water resources management plan allow South East Water to cope with the Government housing targets for Tonbridge and Malling? South East Water says that the increases will not be sufficient to meet the Government housing targets.
