The Solent Mitigation Partnership offers a unique administration process backed by 16 Local Planning Authorities.

This approach has enabled us to provide one of the lowest administration fees on the market. Additionally, our nutrient credit reservation service means we can support developers through their planning application before making a long-term investment to secure mitigation.

We provide a credit reservation service to accommodate the varying requirements of Local Planning Authorities (LPAs). While some LPAs require nutrient mitigation to be secured prior to granting planning permission, others stipulate that it must be in place as a condition of discharge. Our flexible approach ensures developers can meet their LPA expectations with confidence.

Funds generated through the purchase of nutrient credits are reinvested in new mitigation schemes, supporting sustainable development across the Solent region.

Permanent Credits

Nutrient credits can be purchased to fulfil nutrient mitigation requirements once planning permission is granted.

  • Nitrogen Credit: £3,250
  • Phosphorus Credit: £50,000
  • Administration Fee: £750

One nutrient credit equates to 1 kg of total nitrogen (kg/TN) or 1 kg of total phosphorus (kg/TP). Unlike some providers, our credits are sold in fractional units to suit the needs of your development.

Please note: VAT applies to all purchases.

Once payment is received, a Credit Sales Certificate will be issued to confirm that nutrient credits have been purchased for your development. This certificate serves as formal evidence that appropriate nutrient mitigation has been secured and should be submitted to your local planning authority as part of the planning process.

Temporary Credits

This type of temporary (or bridging) mitigation is available to offset the period until the large wastewater treatment works in the Solent complete their upgrade in 2030. Temporary mitigation is only available in certain parts of the Solent catchments where there is ample supply of mitigation to meet demand.

  • Temporary Nitrogen Credit : £325
  • Temporary Phosphorus Credit : Not available
  • Administration Fee: £750
  • End of temporary period: 31 December 2030

One nutrient credit equates to 1 kg of total nitrogen (kg/TN) or 1 kg of total phosphorus (kg/TP). Unlike some providers, our credits are sold in fractional units to suit the needs of your development. Both temporary and permanent credits should be purchased at the same time.

Please note: VAT applies to all purchases.

Reserve Credits

Reserving permanent credits secures them for a development while planning permission is being sought.

  • Reservation Fee: £750 +VAT
  • Reservation Period: 12 months

Once payment is received, a Credit Reservation Letter will be issued to confirm that nutrient credits have been reserved for your development. This letter can be submitted to the local planning authority as evidence that appropriate nutrient mitigation has been secured.

If planning permission is granted during the reservation period, the credits can be purchased. If planning permission is refused, the reservation will lapse with no further obligation.

If a decision has not been made by the end of the reservation period, credits can be re-reserved for another 12 months at a cost of £750 +VAT.
