A quick and easy share dealing service to either sell or buy more shares is provided by Link Group.

An online and telephone facility is available providing Harbour Energy plc shareholders with an easy-to-access and simple-to-use service.

There is no need to pre-register and there are no complicated forms to fill in. The online and telephone dealing service allows you to trade "real time" at a known price which will be given to you at the time you give your instruction.

To deal online or by telephone all you need is your surname, postcode, date of birth and Investor Code (IVC), which can be found on a recent share certificate, statement or tax voucher produced by Link Group*. Please have the appropriate documents to hand when you log on or call, as this information will be needed before you can buy or sell shares.
