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

Our expert team is here to help guide you through the buying process, our simplified approach has 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 local mitigation schemes, supporting sustainable development across the Solent region.

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: 1 April 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.

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.

Purchasing temporary, and permanent credits - 10% deposit

This offer is for smaller sites whose total credit value is less then £75k. The SMP would require payment upfront of the temporary credits and a 10% deposit for the permanent credits. This includes an administration fee of £750 + VAT.

The remaining payment must be within 12 months or prior to commencement of development, whichever is the earliest. The SMP will issue an invoice for remaining amount at the end of month 11 if you have not paid in full before that.

A condition will be requested on your planning approval linking the nutrient mitigation scheme directly to the SMP credits and for the condition to be discharged prior to commencement of development (rather than occupation).

The SMP will provide a sales certificate for the temporary credits on initial payment and another sales certificate for the permanent credits once you have paid the remaining in full.

We will only provide a refund if your planning application is withdrawn or refused but this will invite a 10% restocking fee, that would include the amount taken for the 10% deposit as well.

Consequence of not finalising the purchase, the SMP will inform your planning authority that the permanent credits have not been purchased and retain all of the money you have already paid. The credits will no longer be held for your development and resold to another development.

Your planning approval would be at risk if you do not complete the requirement for permanent credits.

This soultion can be completed in about a week.

Mitigation Purchase Agreement

Objective of the agreement – The SMP will offer to developers the sale of temporary nitrogen credits. The SMP will provide these temporary credits as long as the developer commits to purchase their permanent credit requirements as well.

The contract will allow you to pay for the temporary credits and then phase or defer payment for the permanent credits until a specific date(s) or action(s) in the housing development e.g. commencement of development or occupation.

There are areas that are non-negotiable:

  • The price of the mitigation
  • The contract will be linked to the development only
  • A clause will require you to have a condition within your planning permission to the purchase of the permanent credits for that development from the SMP
  • You will transfer the contract to any new owner of the development as a condition of the sale
  • You pay the SMP’s admin and legal fees as well as your own

The areas we are open to discuss are:

  • Payment timeframe for the temporary credits
  • Deposit amount for the permanent credits
  • Planning actions or phased payment schedule for the purchase of permanent credits
  • Returns/Refund policy if planning application withdrawn/rejected
  • Consequences of termination of contract if planning permission agreed but development not taken forward

We expect that the high level negotiations will take about a month and then another month to refine the contract ready for us to sign. If this is of interest to you please contact the SMP via enviromentalmitigation@fareham.gov.uk
