Shareview service 

The Shareview service from Equiniti allows you to manage your shareholding online. It gives you:

  • Direct access to data held on your behalf on the share register, including recent share movements and dividend details
  • The ability to change your address or dividend payment instructions online.

To visit the Shareview website, go to www.shareview.co.uk. There is no charge to register but you will need the ‘shareholder reference’ printed on your proxy form or dividend stationery.

When you register with the site, you can register your preferred format (post or email) for shareholder communications. If you select email as your mailing preference, you will be notified of various shareholder communications, such as annual results, by email instead of post.


Unsolicited mail

Costain is legally obliged to make its share register available to the general public. Consequently, some shareholders may receive unsolicited mail, including correspondence from unauthorised investment firms. Shareholders who wish to limit the amount of unsolicited mail they receive can contact The Mailing Preference Service at www.mpsonline.org.uk or on 0207 291 3310 or at:

The Mailing Preference Service Freepost 29
London W1E 0ZT

The Orr Macintosh Foundation (ShareGift) operates a charity share donation scheme for shareholders with small parcels of shares whose value makes it uneconomic to sell them. Details of the scheme are available on the ShareGift website at www.sharegift.org

Donating shares to charity in this way gives rise neither to a gain nor a loss for Capital Gains Tax purposes. This service is completely free of charge and Equiniti can provide stock transfer forms on request.
