Access to Standards

NSI helps you obtain the Standards you require, with a choice of three cost-effective options: 1) the NSI Standards Online Subscription service 2) printable electronic copies and/or 3) hard copies of Standards.  

1. NSI Standards Online Subscription Service

NSI offers an online Standards Subscription Service in conjunction with the British Standards Institution (BSI), exclusively available to NSI approved companies and applicants who require only those Standards specific to NSI approval schemes.

Individuals subscribing to NSI’s Online Standards Subscription Service do so for a nominal annual fee, providing significant cost savings.

Once subscribed you are given access to those Standards. Once your payment has been received you will be given access to the Standards from the date your subscription is activated until the end of the coming March. Thereafter you will be billed annually in April for the following 12 months ending in March.

If you are interested in NSI's Standards Online Subscription Service, click on the 'Apply here' button below to take you through to the full Terms and Conditions and Application Form, with pricing details.

Agreement to the Terms & Conditions is required when you apply.

Please note:

  • The fee entitles you to download, view and save the Standards to one designated desktop only within your organisation.
  • Standards are not printable and must not be saved on an internal system (intranet) or external network or website.
  • Standards must not be copied or transferred to any other device via an internal system (intranet) to any colleague/associate within or outside your organisation, without prior permission from BSI.
  • The subscription is for a 12 month duration ending in March annually. During this period standards are refreshed every 3 months ensuring NSI approved companies have access to the latest versions.
  • Companies seeking other standards should see options 2 and 3 below or contact BSI directly.

N.B. NSI is currently unable to offer BS 7671:2018 Requirements for Electrical Installations (IET Wiring Regulations Eighteenth Edition), via this subscription service, due to it being available in paper format and has a shared copyright restriction. To obtain a copy of this Standard, please contact BSI directly.


2. Electronic copies of standards

Purchase a printable electronic version (pdf format) of any Standard offered by the BSI, through NSI at a preferential rate. Each document is covered by a single copy licence, so it cannot be shared amongst colleagues or third parties, but one hard copy may be printed. Standard(s) will be emailed to a single address. If you require a Standard for multiple users, the BSI offers a multi user licence and the cost of the licence will be based on the number of sites and users and is therefore bespoke.

3. Hard copies of standards

Purchase single or multiple hard copies of any Standard offered by the BSI through NSI at a preferential rate.


Ordering electronic and hard copies

To order electronic (pdf) or hard copies of Standards, please email our Accounts Team specifying the Standards you require and the format (pdf or hard copy). You will then be provided with price information (at the NSI preferential rate), once accepted, we can send you a pro-forma invoice or you may pay by BACS or card. Once payment has been received, we will place the order with BSI.
