HOU3 - Affordable Housing
Thresholds and Percentage
1) The council will seek an overall provision of at least 40% of all new
housing as affordable housing (by net additional unit), incorporating a mix
of tenures. All new development resulting in a net gain of one or more
dwellings will be expected to contribute to the provision of affordable
housing. On specialist housing schemes for older people, these thresholds
will apply except in the case of development falling within a C2 use class.
Split
2) 70% of affordable housing should be for rent and 30% for affordable home
ownership and have regard to the following:
a) Affordable housing for rent includes Social Rent and affordable
rent (and can include affordable private rent). As a guide 70% of
affordable housing for rent provision should be Social Rent and
30% should be for affordable rent.
b) Affordable home ownership includes First Homes and shared
ownership. First Homes and shared ownership products are
preferred; however, other types of affordable home ownership
products will be considered on a case- by-case basis. As a guide
50% of affordable home ownership provision should be First
Homes and 50% should be shared ownership.
3) In calculating the percentage of affordable units to be provided as part of a
development scheme, the affordable housing requirement will normally be
‘rounded up’ to the nearest whole number.
4) Where development would affect existing affordable dwellings, permission
will only be granted where this would not result in a net loss of affordable
housing, and where the proposed tenure mix would meet affordable
housing needs of the community.
Green Belt
5) All major development involving the provision of housing in the Green Belt
(i.e. sites for 10 or more homes; or with a site area of 0.5 hectares or
more) should provide at least 50% of the total housing provision as
affordable housing. Any development in the Green Belt resulting in a net
gain of 1-9 dwellings should provide at least 40% of the total housing
provision as affordable housing, as set out in paragraph 1 of this policy. An
affordable housing split in line with policy criterion 2 is expected.
Rural Exception Sites
6) Small-scale proposals delivering 100% affordable housing in perpetuity
within and immediately adjacent to the village core areas of Bedmond and
Sarratt may be supported within the Green Belt where these are
evidenced to provide affordable housing to meet identified local community
needs. Such proposals must accommodate households which contain
current residents or have an existing family or employment connection (to
the respective village) in perpetuity. A minor degree of market housing
may be acceptable where it is required to support the delivery of affordable
housing on the site. If market housing is proposed to support the delivery
of affordable housing on the site, a viability assessment must be submitted
as part of the application to justify this.
7) Affordable housing should reflect the mix of sizes and types required in the
district as identified within the Housing Mix and Type Policy, the most up-
to-date Local Housing Need Assessment (LHNA) and subsequent
updates, the council’s Housing Register and any relevant Neighbourhood
Development Plan.
Mode of Affordable Housing Provision
8) In most cases, affordable housing provision should be made on site,
however, on small sites delivering between one and nine dwellings,
contribution to affordable housing may be made through commuted
payments. Such payments will be broadly equivalent in value to on-site
provision of affordable housing for rent, but may vary depending on site
circumstances and viability. Payments will fund the development of
affordable housing on other sites within the district.
9) To ensure community cohesion and good design, affordable homes must
be fully integrated in the design of the overall scheme, being physically
and visually indistinguishable from market units and dispersed across the
site in clusters appropriate to the size and scale of the development.
Designs resulting in high maintenance or service charges should be
avoided.
Delivery
10) Affordable housing requirements that have been determined on the basis
of viability and site-specific viability information seeking to justify an
alternative level or mix of affordable housing will therefore only be
accepted in exceptional cases. Viability assessments should be
undertaken in accordance with the recommended approach set out in
national planning guidance, including standardised inputs, and will be
made publicly available.
11) Where a reduction in affordable housing is justified, the council will seek to
secure the preferred tenure split as a priority over a potentially higher total
percentage of affordable housing which would not be consistent with
meeting priority needs. Such proposals will also be subject to detailed
review mechanisms throughout the period up to full completion of the
development, including an advanced stage review mechanism.
12) Where developments would trigger affordable housing requirements,
application of the Vacant Building Credit will only be appropriate in
demonstrated exceptional circumstances, and where a proposal would
meet all of the following criteria:
a) It is clearly demonstrated that the site would otherwise not come
forward for any form of redevelopment at any point over the
medium to long-term;
b) All buildings within the site boundary are vacant at the time the
application is submitted;
c) There are no extant or recently expired permissions on the site for
any proposed use class;
d) The proposal does not involve the loss of any capacity to meet
other development needs from a site allocated for non-housing
development; and
e) The building has not been made vacant for the sole purpose of
redevelopment, evidenced by provision of marketing and vacancy
evidence for a continuous period of five years (up to the point of
submission of an application).
Local Connection Criteria
13) All forms of affordable housing (except homes for social and affordable
rent) should be allocated in accordance with the Council’s ‘Local
Connection Criteria’, set out below or by any subsequent detailed
guidance. This will be secured by planning obligation.
First Homes
14) First Homes are required to be sold at a minimum discount of at least 30%
of the market value of homes available for sale locally which are of the
same size and type as those proposed. The minimum discount will be
secured in perpetuity.
Reasoned Justification:
5.38 The NPPF advises that affordable housing should not be sought for residential
developments that are not major developments, other than in designated rural areas
where policies may set a lower threshold of five units or fewer. However, the local
circumstances in Three Rivers are considered to justify an alternative approach to
require all developments resulting in a net gain of housing to contribute to affordable
housing provision. This is on the basis of the acute need for affordable housing in the
district demonstrated by the LHNA, the council’s “Evidence Relating to the Application
of the Affordable Housing Threshold in Core Strategy Policy CP4: Affordable
Housing” documents12, and the crucial role that smaller sites delivering fewer than 10
dwellings has played in delivering housing historically which is expected to continue
in future. These factors are considered to outweigh the guidance within the NPPF
and justify the approa ch within the Affordable Housing Policy to require all sites
resulting in a net gain of dwellings to contribute to affordable housing provision in the
district, and this approach has been supported in recent appeal decisions in the
district.
5.39 The LHNA demonstrates that the median house price in Three Rivers during in the
year to September 2022 was £560,000. This is significantly above the Hertfordshire
average of £512,940 and the East of England average of £328,000 during the same
period. Month ly rents across all sizes of accommodation are similarly above
Hertfordshire and England averages within Three Rivers.
5.40 Affordability ratios in Three Rivers and across the South -West Hertfordshire area
have deteriorated significantly since 1997 and lower quartile house prices in the
district were 12.24 times higher than lower quartile incomes in 2024. The affordability
of housing therefore remains a critical issue in Three Rivers and will continue to be
so for the foreseeable future.
5.41 The LHNA considered needs for affordable housing within the district and identified
an annual net need for affordable housing in Three Rivers over the period 2024-2040
of 527 affordable homes per year. When split between rented affordable need and
affordable home ownership need, this overall identified need of 527 affordable homes
a year equates to a need of 364 rented affordable homes (including Social Rent and
12 https://www.threerivers.gov.uk/services/planning/planning-applications/latest-appeals-cp4
affordable rent) and 163 affordable home ownership dwellings (including First
Homes, shared ownership etc).
5.42 Given the substantial need for affordable housing in the district, it is also essential
that development does not lead to a reduction in the overall supply of affordable
housing, or to changes to the tenure of affordable housing which is provided so that
it is less well suited to meet demonstrated local needs. Such proposals would
undermine the overall approach to the supply of affordable housing in the district and
will be resisted
Rented Affordable Need
5.43 The LHNA sets out that “there are therefore policy choices to be made by individual
authorities around how policies are crafted … the analysis is however clear that there
is need for both social and affordable rented homes”. The LHNA further adds that
“decisions should be influenced by individual authorities’ priorities, the results of
viability evidence and funding availability”. With regard to the tenure of affordable
housing for rent, local evidence suggests that the greatest need in the district is for
Social Rented housing, followed by Affordable Rent.
5.44 However, when benefits are taken into account, the LHNA notes that for households
claiming Household Benefit, an affordable rent may be appropriate as long as the
Housing Benefit is able to cover all of the rent, whilst for households with an income
that would allow them to afford an affordable rent it is arguable that a social rent would
be more appropriate as the housing costs would be less of a strain on household
finances.
5.45 Affordable rent should be genuinely affordable, with rents at around 60% of median
market values (including service charges).
5.46 The council acknowledges that requiring a higher proportion of affordable homes for
rent, will impact on the overall level of affordable housing that may be delivered.
However, these are the most urgent and pressing needs for housing in the district
and th e council will therefore prioritise the delivery of a greater proportion of
affordable housing for rent rather than a higher total level of affordable housing
delivery through, for example, a higher proportion of affordable home ownership. A
tenure mix in accordance with Policy X (Housing Mix and Type) will therefore be
sought.
Affordable Home Ownership Need:
5.47 The LHNA also indicates that in addition to the requirement for affordable housing for
rent, that there is a case for setting out policies in Local Plans which support provision
of a range of affordable home ownership products. Such products include First
Homes, shared ownership and rent to buy.
5.48 First Homes are a specific type of discounted market sale housing and meets the
definition of ‘affordable housing’ for planning purposes. First Homes are discounted
market sale units which:
a) must be discounted by a minimum of 30% against the market value;
b) are sold to a person or persons meeting the First Homes eligibility criteria
c) on their first sale, will have a restriction registered on the title at HM Land Registry
to ensure this discount (as a percentage of current market value) and certain other
restrictions are passed on at each subsequent title transfer; and,
d) after the discount has been applied, the first sale must be at a price no higher than
£250,000
5.49 National standard criteria apply to First Homes eligibility and will be considered at the
time of the planning application.
5.50 The council can exercise flexibility to lower the price cap; increase the discount level
and/or reduce the income cap, provided there is local evidence to justify doing so.
The LHNA suggests the possibility of raising the discount levels to 40% in Three
Rivers, but the case for higher discounts needs to be balanced against scheme
viability and the potential knock-on effect on other tenure types in the scheme. As
such, higher discounts can be considered, where this can be viably achieved.
Local Connection Criteria
5.51 To demonstrate a local connection, applicants for Affordable Housing (except social
and affordable rent) that are built in Three Rivers will need to provide evidence for
one of the following:
• Have current residence (by choice) in the district and have lived in the
district for at least five out of the last six years; or
• Work in Three Rivers in employment other than of a casual nature as
defined by Local Government Association Guidelines. For the purposes of
this policy this will be defined as having had permanent work with a
minimum of a 16 hour contract per week for the previous 12 months, and
without a break in the period of employment for more than 3 months; or
• Have family connections in Three Rivers with a member of their household,
parents, adult children or adult siblings who have been residents in the
district for at least the last 10 years.
• Have caring responsibilities to a family member within the district or are
cared for by a family member within the district
• Are a Keyworker within the district or nearby (further details will be provided
by guidance)
5.52 Other exceptional circumstances not listed above may be considered on a case -by-
case basis.
5.53 In recognition of the unique nature of their circumstances, all Armed Forces veterans,
irrespective the length of Service or when this Service ended are exempt from any
local connection testing restrictions. This includes:
• Current serving members of the Armed Forces;
• Former members of the Armed Forces;
• Bereaved spouses or civil partners of Armed Forces members where (i) the
bereaved spouse or civil partner has recently ceased, or will cease, to be
entitled to reside in Ministry of Defence accommodation following the death
of their Service spouse or civil partner, and (ii) the death was wholly or partly
attributable to their Service;
• Adult children of serving Armed Forces members who need to move out of
family accommodation;
• Serving or former members of the Reserve Armed Forces who are suffering
from a serious injury, illness or disability which is wholly or partly attributable
to their Service;
• A divorced or separated spouse or civil partner of a Regular Armed Forces
member who needs to move out of accommodation provided by the Ministry
of Defence due to a relationship breakdown
5.54 The above list is not exhaustive and the council may grant an exception to the local
connection criteria on the grounds of exceptional circumstances, to an Armed Forces
veteran or family member who may not wholly fulfil one of the above.
5.55 Applicants with a local connection will be expected to be prioritised for the first three
months of marketing. Council officers will monitor compliance with requirements set
out in a s106 and other planning obligations.
5.56 It must be noted that future detailed guidance will supersede the above criteria.
Rural Exception Sites
5.57 There are fewer opportunities to build new homes in the district’s smaller villages
surrounded by, or designated as Green Belt due to more restrictive policies on
housing in countryside and particularly in the Green Belt. However, an element of
new development can help to support these communities. The NPPF recognises this
and enables the provision of limited affordable housing for local community needs
under policies set out in the development plan, including policies for rural exception
sites. Proposals for rural exception sites delivering 100% affordable housing within
and immediately adjacent to the village core may be supported (including in the
Green Belt) where these are evidenced to provide affordable housing which would
meet identified local communi ty needs. The type and size of affordable housing
provided on such sites must address identified needs in the individual village or the
area it serves which is defined as the village or parish in which it is located.
Specialist Housing
5.58 In relation to specialist housing (such as extra care housing), it is recognised that
provision of affordable housing may be particularly difficult to achieve from both a
viability and practical perspective), as highlighted within the LHNA. As such,
affordable housing provision will not apply in the case of development falling within a
C2 use class. In other cases (i.e. where development falls within a C3 use class), a
viability assessment will be required to demonstrate if an affordable housing
contribution is not viable.
Provision for Gypsies, Travellers and Travelling Showpeople
5.59 Gypsies, Travellers and Travelling Showpeople have particular accommodation
needs that require additional consideration. To ensure that members of these
communities are able to access decent and appropriate housing wit
