Affordable Housing

Arun experiences high levels of housing need and housing affordability is a major issue locally due to the relationship between house prices and household income. In implementing its Affordable Housing Policy, the Council will seek 30% affordable housing on-site on residential developments of 11+ residential units. Affordable housing is social rented, affordable rented and intermediate housing, provided to eligible households whose needs are not met by the market; eligibility is determined by the Council’s Allocations Policy. Affordable housing should include provisions to remain at an affordable price for future eligible households or for the subsidy to be recycled for alternative affordable housing provision. Affordable housing which does not meet the prescribed definition in the National Planning Policy Framework (NPPF) will not be considered as affordable housing for planning purposes.

The Council’s full Affordable Housing Policy is listed below:

Policy AH SP2

Affordable Housing

For all development s of 11 residential units or more the Council will require a minimum 30% of the total number of units proposed on site to be provided as affordable housing on the same site in the first instance.

Where it can be proven, however, that 30% affordable housing provision is not viable, then a reduction in the amount of affordable housing on a site or off-site provision as part of another development within Arun District  may be considered (as agreed with the local planning authority). The provision of affordable housing on a  site at less than 30% or an alternative site or by way of a commuted sum will only normally be allowed in very exceptional circumstances if supported by robust evidence including, where appropriate, viability evidence.

The council will negotiate the affordable housing tenure mix on development sites from an initial position of 75% rent and 25% intermediate housing.

Affordable housing must be visually indistinguishable from market housing with large groupings of single tenure dwellings or property types avoided. Affordable housing units shall be permitted in small clusters throughout development schemes. The affordable dwelling mix should comprise of the following range of homes unless evidence indicates otherwise.

1 bedroom 35-40%

2 Bedroom 35-40%

3 Bedroom 15-20%

4+ Bedroom 5-10%

Provision of affordable housing can be by either an Arun preferred Register Partner, an Affordable Housing Provider or the Council. Al providers will be required to sign and adhere to the principles of the Council’s Developer and Partner Charter Plus.

Affordable housing will be made available for households on the Council’s housing register or on the Homebuy Zone Agent’s register, with nominations made by the Council from those registers.

All planning applications that include residential development, either in whole or in part, must include an Affordable Housing Statement.

If it is agreed with the Council’s Housing Strategy and Enabling Manager that on-site delivery of affordable housing on developments of 11+ units is neither viable nor practical, the Council will accept a commuted sum payable in lieu of on-site affordable housing of £80,000 for each foregone affordable dwelling. This sum will be included in the S106 agreement and will be payable in full on completion of the development.


Council's retained consultant for assessing developer viability appraisals

Dixon Searle Partnership (DSP) ( are the council’s retained consultant for assessing developer viability appraisals (DVAs). Developers/applicants who provide the council with a DVA as evidence as part of a residential planning application will have their appraisal referred to DSP and must pay the referral cost to DSP at the point of referral by the council. DSP will issue an invoice to the applicant and will proceed with their DVA review on receipt of payment. Please note the Council will publish developer viability appraisals in full on our website if the application fails to meet the Council's affordable housing policy requirements

For more information regarding the referral cost and the information required for the review please see  also include the financial appraisal checklist.
