TONBRIDGE, England, April 2, 2026, 14:06 BST
- Tonbridge and Malling has started requiring planning applicants to tackle water capacity issues, with certain proposals already given the nod now under review.
- South East Water informed local lawmakers it can provide for just 6,318 more homes by 2042—well under the nearly 19,700 homes outlined in the borough’s draft plan.
- Ofwat has put forward a £22 million fine tied to earlier supply failures that impacted upwards of 286,000 people, and a different investigation is now looking into the winter outages.
South East Water’s ongoing outages are rippling through West Kent’s housing and property scene. Tonbridge and Malling Borough Council has started requiring planning applicants to demonstrate sufficient water capacity, while the Telegraph noted Thursday that one Kent retiree delayed downsizing after recurring supply breakdowns. This is shifting from a simple supply problem—now it’s determining what councils will greenlight and when movers take the plunge.
Timing is key here: local officials want to ramp up housebuilding, but the utility insists it can’t handle growth beyond its existing water supply plan. Ofwat, for its part, is weighing a £22 million penalty tied to previous supply failures. Ministers, meanwhile, say they’re looking at quick fixes to keep planning applications from stalling.
An April 1 planning report for a proposed 17-home development in Hadlow noted the application was returned to committee after South East Water’s capacity feedback became a material planning factor—meaning councillors are now required to consider it before approving the plans. The borough has clarified that fresh applications, plus certain projects previously cleared in principle, must now demonstrate either sufficient existing water infrastructure or show it can be provided in time.
During a Westminster Hall debate on March 24, Conservative MP Tom Tugendhat revealed that South East Water had informed Tonbridge and Malling it could support just 6,318 new homes up to 2042. That figure sharply contrasts with the roughly 19,700 homes outlined in the borough’s draft local plan, putting a utility shortfall front and center in the government’s housing agenda for Kent.
South East Water hasn’t ruled out connecting the extra homes entirely, but says its current Water Resources Management Plan—a five-year strategy—was based on older housing estimates. Nick Price, head of water resources at the utility, says the plan doesn’t allow for enough “water supply headroom” to cover the higher growth now on the table. Updated projections will feed into the next plan, which the company expects to draft for 2029. The Independent
The impact isn’t limited to developers. According to The Telegraph on Thursday, Kent retiree Gill Knox said she’s been unable to sell or downsize her home due to repeated outages, rejecting a £325 compensation offer from South East Water. Meanwhile, ITV reported Tuesday that Skinners’ Kent Academy in Tunbridge Wells claims it’s still owed around £30,000. Sixteen schools have already turned to Kent County Council for help chasing compensation.
Back in March, Ofwat proposed a £22 million penalty—now out for consultation through April 13—over supply failures from 2020 to 2023 that affected upwards of 286,000 people. Interim chief executive Chris Walters pointed to “significant failings” at South East Water that led to “major disruption”. Meanwhile, the regulator is also probing outages from December 2025 and January 2026. South East Water admitted that, at one point, 30,000 customers were left either without water or dealing with low pressure. Ofwat
The debate has turned sharply political. Mike Martin, Liberal Democrat MP for Tunbridge Wells, wants Ofwat to drop the penalty and instead force a mandatory investment plan, targeting upgrades at the Pembury treatment works. He described the site as a “single point of failure” in the area’s water network. ITVX
South East Water has kicked off a six-month resilience effort, it said in a March 18 update. Engineering projects and operational tweaks—backed by shareholders—are now in progress, aiming to lower outage risks across Tunbridge Wells, Maidstone, Canterbury, Whitstable, East Grinstead, and Crowborough. The company also noted that an independent investigation into the Pembury incident is expected to deliver its findings in April. “We are urgently reducing our risk of supply interruptions,” chief executive David Hinton said.

Yet timing remains a problem—if the repair plan drags, it could miss the current planning cycle. Officials told Parliament they’re looking at quick fixes to push planning applications and local plan work along. The government’s water delivery taskforce claims it’s already managed to unlock 10,000 homes in places like Oxford, Cambridgeshire, and north Sussex. Still, South East Water’s next comprehensive planning cycle doesn’t land until 2029, so for now, councils and developers are left hashing out water supply adequacy one project at a time.
For both West Kent households and local builders, the South East Water dispute is now split between two fronts: immediate worries over service and compensation, and a slower-burning debate about whether the network can handle future housing growth. Until the regulators, ministers, and the company come to an agreement, water stays a drag on new builds—and even routine moves.
