IAS members have the option to join the National Allotment Society (NAS) through our affiliation.

NAS is the national organisation representing allotment holders across the UK. It provides additional benefits, services, and support beyond IAS membership.

NAS membership is administered separately from IAS and follows the IAS/NAS membership cycle.
If you are already a current NAS member (2025–2026) and pay online now, your payment will be applied to the 2026–2027 NAS membership year. You do not need to take any further action.
If you are a new NAS member, you may choose either:
— to join for the current NAS year, which is valid until 31 May 2026 (and receive benefits this year, such as Kings Seeds seeds scheme, see below) or
— to join for the 2026–2027 NAS year from June 2026.
You will be provided with a choice on the form.
Please note that NAS membership and access to NAS benefits, including the Kings Seeds scheme, do not begin immediately after online payment. IAS must manually update the NAS database first. We will let you know once your NAS membership has been processed and activated.
If you want to maximise the length of your membership and do not need NAS benefits immediately, you may prefer to wait until June 2026 before joining as a new NAS member.

IAS members can join NAS for £3.50 per year as affiliated members.

For comparison, individual NAS membership outside an affiliated society costs £25 per year.

NAS membership is available only to current IAS members when joining through the Society.

NAS membership provides additional benefits, including:

• Discounted seeds through the Kings Seeds scheme
• Access to the ‘Allotment Gardener’ magazine (digital and printed)
• Expert horticultural advice and support
• Initial legal advice and access to discounted legal services
• Retail discounts on a range of gardening products
• National representation for allotment holders
