Shareholder Information

Shareholder Information

Managing your shares

Please contact our Registrar, Equiniti, to manage your shareholding. Further information is also available through the Shareholder Centre on our website, including frequently asked questions and forms available to download to assist in:

  • transferring your shares;
  • changing your registered name or address;
  • registering a lost share certificate and obtaining a replacement;
  • consolidating your share certificates;
  • managing your dividend payments;
  • buying, selling or transferring shares through Centrica FlexiShare;
  • notifying the death of a shareholder; and
  • registering for electronic communications.

You can also manage your shareholding online by registering for Shareview via the electronic communications section of the Shareholder Centre.

When calling Equiniti or registering online, you should have your shareholder reference number at hand. This can be found on your share certificate or dividend tax voucher. You should also include this on any correspondence.

If you hold less than 2,500 shares, you will be able to change your registered address or set up a dividend mandate instruction over the phone. For security, if you hold more than 2,500 shares, you will need to put this in writing.

You should note that if you receive more than one copy of documents that we send you, it is likely that you have more than one account on the share register, perhaps with a slightly different name or address. If you write to Equiniti and give them the shareholder reference numbers, they will be able to combine your accounts into one.

We are currently working with a specialist tracing agency, ProSearch, to identify shareholders whose details are not up to date and who have outstanding cash entitlements. Please notify Equiniti when you move house to ensure you continue to receive all our communications.

Centrica FlexiShare

FlexiShare is a convenient way to hold Centrica shares without a share certificate. Your shares would be held in a nominee company, Equiniti Corporate Nominees Limited, however your rights to attend and vote at general meetings are the same as if the shares were held in your own name. Holding your shares in this way is a free service and comes with a number of benefits:

  • low cost share-dealing facilities, provided by three independent providers, full details of which are available on the Shareholder Centre together with dealing charges;
  • quicker settlement periods for buying and selling shares; and
  • the opportunity to elect for the Dividend Reinvestment Plan.


Dividends on Centrica shares are usually paid in June and November. Details of the interim and final dividends for the year ended 31 December 2011 can be found in note 10 to the Financial Statements.

You are encouraged to receive your dividends directly to your bank or building society account. This means that you will receive the money on the day it is paid and avoids any risk of missing cheques. If you do choose to receive your dividends in this way, a consolidated tax voucher will be sent to you in March each year.

If you do not have a UK bank or building society account to receive dividend payments, Equiniti are able to pay dividends in local currencies in over 30 countries. For a small fee, you could have your dividends converted from sterling and paid into your designated bank account, usually within five days of the dividend being paid.

Shareholder communication

Due to changes in legislation, it is now possible for us to communicate to a greater extent with shareholders using our website. We strongly encourage our shareholders to receive communications electronically as it allows us to make considerable savings, both environmentally and financially, and allows you to:

  • view the Annual Report and Annual Review on the day they are published;
  • receive an email alert when shareholder communications are available;
  • cast your AGM vote; and
  • manage your shareholding quickly and securely.

Our website contains a wealth of other information, including:

  • regular updates about our business;
  • comprehensive share price information;
  • financial results; and
  • dividend payment dates and amounts.

Buying and selling shares with a share certificate

If you wish to buy or sell Centrica shares and hold a share certificate, you can do this:

  • by using the services of a stockbroker or high street bank; or
  • through telephone or online services.

In order to sell your shares in this way, you will need to present your share certificate at the time of sale.

American Depository Receipts (ADR)

We have an ADR programme, trading under the symbol CPYYY. Centrica's ratio is one ADR being equivalent to four UK shares. Further information is available from the Shareholder Centre or please contact:

It may be that you have a small number of shares and that it would cost you more to sell these than they are worth. It is possible to donate these to ShareGift, a registered charity, who provide a free service to enable you to dispose charitably of such shares. More information on this service can be obtained from www.sharegift.org or call +44 (0) 207 930 3737.

Scams and frauds

You should be wary of any unsolicited communications, such as:

  • offers to buy or sell shares at a discount;
  • opportunities to receive free company reports;
  • free financial advice; and
  • chances to invest in carbon credit trading schemes.

These approaches may be part of financial scams and can be very persistent, using hard sell tactics to persuade you to buy or sell shares or invest in carbon credit schemes.

The FSA provide comprehensive advice in relation to scams and frauds. Detailed information can be found on their website www.fsa.gov.uk/pages/consumerinformation.

Any share-dealing facilities endorsed by the Company will be included in our mailings.
