In accordance with national guidance published by the Department for Communities and Local Government, Three Rivers District Council has created a list of local requirements for the validation of planning applications. This has been incorporated into a validation checklist which encompasses national requirements (including the application form, the correct fee, ownership certificates and other specific details) as well as local validation requirements.
Please note a planning application cannot be processed until all the necessary supporting information and the appropriate fee is received.

Following changes to the National Planning Practice Guidance, with effect from 23 May 2016, financial contributions towards affordable housing will no longer be sought from developments of 10-units or fewer with a maximum combined gross floorspace of no more than 1,000sqm.
For sites above these thresholds, if viability is an issue a Viability Assessment / Financial Appraisal must be submitted. This viability information will be assessed by an independent financial advisor, the cost of which shall be borne by the applicant/developer. These costs are:
9 units or less: £1500 plus VAT
10 or more units: £2000 plus VAT
Large schemes: Fee to be negotiated on an individual basis
Please note that the relevant fee (payable to Three Rivers District Council for inward transmission) must be paid up-front at the time of validation, and must be a separate payment to the planning application fee.
Please note that the Council may be obliged to disclose documents under the Freedom of Information Act and the Environmental Information Regulations and cannot agree to accept documents in confidence or on any basis that restricts its disclosure obligations as a public authority.
Energy Statement Requirement:
Policy CP1 of the adopted Core Strategy requires all applications for new residential development of one unit and above and all new commercial development to be accompanied by a CPLAN Energy Statement and Sustainability Checklist to demonstrate the extent to which sustainability principles have been incorporated into the location, design, construction and future use of proposals, and the expected carbon emissions.
The CPLAN Energy Statement and Sustainability Checklist will not be available from 21 March 2016. From this date, applicants will not be able to submit a CPLAN Energy and Sustainability Statement but should submit an Energy Statement demonstrating the extent to which relevant proposals meet the requirements of Policy DM4 of the Development Management Policies document which sets out that developments must produce at least 5% less carbon dioxide emissions than Building Regulations Part L (2013) requirements having regard to feasibility and viability. For building conversions, development proposals must still demonstrate that there would be an overall improvement in the energy performance of the building. Guidance on producing an Energy Statement is available at Guidance on producing an Energy Statement (pdf)
Drainage Strategy Requirement:
The Government has introduced a requirement for all major development proposals to include Sustainable Drainage Systems (SuDS) and details of drainage would be required as a Drainage Strategy. Guidance on requirements and providing Drainage Strategies is available from Hertfordshire County Council as the Lead Local Flood Authority at
