The Nature Restoration Levy Regulations 2026 were made on 10 September 2026 and came into force on 11 September 2026. According to the statutory instrument, they provide the payment, liability and enforcement framework for the levy created under Part 3 of the Planning and Infrastructure Act 2025. For developers, land promoters and SME housebuilders, this is not just a planning technicality. It changes when cash may have to leave a project, who can be pursued if it does not, and how far Natural England can go when payment delays start to affect delivery.

The first point for the market is what the regulations do not do. They do not set a single national tariff. Instead, Natural England will use charging schedules within environmental delivery plans, or EDPs, to set rates or other criteria, taking account of conservation, monitoring and administrative costs, with scope for different charges by zone, use, scale or environmental effect. The explanatory note says payment of the levy can discharge certain environmental obligations, with the proceeds then funding conservation measures set out in the relevant EDP. For business readers, that means the real cost question will often be site specific. A scheme's exposure will depend on which EDP applies, how the charging schedule measures development and whether Natural England offers any instalment structure at all.

The cash-flow pressure is clearest at commencement. The regulations require a condition preventing development from starting until the levy is paid in full or, where Natural England agrees to instalments, the first instalment is paid. For projects relying on tight sequencing between planning, debt drawdown and site mobilisation, that pulls the levy into the early funding stack rather than leaving it as a later compliance item. That matters most where margins are already thin. If a developer has assumed the levy can be settled further down the line, the new rules point the other way. Natural England must also notify the relevant authority once the payment condition has been met, giving the process a formal trigger rather than a looser administrative understanding.

The liability rules are also firmer than many landowners may expect. A developer can assume liability, and an existing liable person can transfer it, but if no one does so Natural England must in many cases move to the owners of the land once the statutory conditions are met. Where sums fall overdue and recovery efforts fail, landowners can again be brought into the frame. In practice, that makes title structure and contract drafting more important. Freeholders and longer leaseholders can find themselves exposed, and multiple liable persons may be jointly and severally responsible unless Natural England apportions liability between material interests. Anyone buying into a consented site or funding one will want clear evidence of who has taken on the levy and whether that exposure can shift later.

The amount itself is not fixed once first calculated. The regulations say the levy amount is based on the charging schedule in force when Natural England accepted the request to pay, then indexed using the RICS CIL Index, with CPI including owner occupiers' housing costs as a fallback if that index is unavailable. Payments are also adjusted for inflation, so delay can increase the cash needed to clear an outstanding balance. There is a second pricing risk around scheme changes. Liable persons must notify Natural England of a material change in the development details used to calculate the levy. If a project grows, phases move or unit numbers change and that is not reported, Natural England can recalculate the charge and add a surcharge where the increase is large enough. For developers used to redesign between consent and delivery, that is a compliance point worth treating seriously.

Natural England has discretion on instalments, but the regulations do not make staged payment a right. It can decide whether instalments are allowed, how many there are and the amount due on each date, and later changes require the consent of every liable person. That makes it sensible to deal with levy timing in option agreements, promotion agreements and development finance documents before the liability notice arrives. There is, however, one practical release valve for overlapping schemes. Payments made for one development can, in certain cases, be moved across to another development on the same land where the first project is not proceeding further. For masterplans that are reworked midstream, that could reduce some stranded cost, although Natural England is allowed to deduct its reasonable administrative costs first.

The enforcement side is where the regulations become genuinely sharp. Failure to assume liability can trigger a surcharge of 2% of the levy amount or £300, whichever is higher, provided the levy is at least £1,000. Late payment can trigger further surcharges at 30 days, six months and 12 months, each set at 5% of the outstanding amount or £300, whichever is higher. Interest also runs on overdue sums at 2.5 percentage points above the Bank of England base rate. If the debt still sits unpaid, Natural England can issue a warning notice and then, after a warning period that can be as short as three days, a stop notice preventing specified activity on the site. The levy is recoverable as a debt, it becomes a local land charge affecting the relevant land, and Natural England can ask the county court for consent to enforce that charge where the outstanding levy amount is at least £2,000. For developers, that reaches well beyond admin risk and into refinancing, sales progression and lender appetite.

There is some procedural balance. Developers and landowners can ask Natural England to review levy calculations or apportionment, and appeals can then go to the Secretary of State. While a review or appeal is outstanding, the disputed amount is not payable, which gives firms a route to challenge figures without immediately falling into default. Still, the commercial message is straightforward. According to the explanatory note, no separate impact assessment was produced for this instrument because one was not required for regulations of this kind, with the wider assessment sitting under the Planning and Infrastructure Act 2025 instead. That leaves businesses to do more of the modelling themselves. The immediate priority is less the legal theory of the levy and more the hard project questions: which EDP applies, what the charging schedule says, who carries the liability, and whether cash flow can absorb payment before works begin.
