Reasonable Cost Contribution
Domestic Development – Reasonable Cost Contribution
Connection costs are specified by our Scheme of Charges. If you’re building a development with assets to be vested, check out our information on reasonable cost contribution below.
'Reasonable Cost Contribution' in relation to new development connections to the public infrastructure
Financial contributions are defined within legislation, in accordance with the Water Industry (Scotland) Act 2002. Scottish Water is required to meet the costs of providing strategic capacity required for new developments (Part 4 infrastructure). Customers are required to meet the costs of providing additional local capacity (Part 2 and 3 infrastructure), subject to a reasonable cost contribution from Scottish Water.
Current maximum values of contribution per house
These values are reviewed on an annual basis through our Regulator, The Water Industry Commissions (WICS).
The maximum value of contribution for new domestic adoptable sewerage infrastructure is up to *£1922.04 per house.
The maximum value of contribution for new domestic adoptable water infrastructure is up to *£1655.33 per house.
(*Figures current as of 1st April, 2019)
Please note: Each development project will have a reasonable cost figure calculated at the design technical audit stage. The figure agreed can vary at any level up to the maximum contribution figure stated, depending on the calculation outcome. When assessing development budgets, do not assume that your development will be eligible for the maximum contribution per property.
Cost contribution - How it is determined
The Provision of Water and Sewerage Services (Reasonable Cost) (Scotland) Regulations 2006, determine what that reasonable cost contribution should be, by specifying what matters will, and will not, be taken into account in calculating the contribution and also by specifying the method of calculation.
The Regulations clarify how the costs of different elements of each new connection are shared between customers and Scottish Water.
The costs associated with all new Part 1 infrastructure are the sole responsibility of the customer.
Extensions or upgrades to the Part 2 or Part 3 elements of the existing water and waste water networks will be funded by the customer. This is subject to a contribution from us, to take account of the future income that will be received from the new connection. This information will directly contribute to the calculation used to confirm the level of contribution from Scottish Water for all related Part 2 or Part 3 costs.
A contribution is available for all new connections whether a new development or a first time connection to an existing property. However, it is not available for the adoption of existing private assets or for the upgrading of existing private infrastructure to adoptable standards.
Definition of Connection Parts
Part 1: The connection from individual premises to a water main or sewer.
Part 2: The water mains and sewers that connect developments e.g. a street of houses to trunk mains and trunk sewers and some sustainable urban drainage systems (SUDS).
Part 3: The local bulk infrastructure, such as trunk mains and trunk sewers, water service reservoirs, waste water pumping systems and some SUDS.
Part 4: The strategic assets such as raw water intakes, water impounding reservoirs, raw water pumping stations and aqueducts, and water and waste water treatment works.
Advising the RCC agreement for your development site
Once we have reviewed your design submissions and supporting materials, and have completed our audit, two copies of a Financial Reimbursement Agreement (FRA) will be issued to you.
This clearly outlines the contributions for your site and what is eligible. It is expected that the Developer/Applicant will review this document, and will sign and retain a copy, and sign a copy to return to our office.
