Wales will shortly undergo the switchover to Digital TV and with it the possibility that some will try to take advantage of any confusion of householders about their individual needs.

The Digital TV booklet distributed to households contains helpful information and a section on the most frequently asked questions relating to the equipment requirements, and a guide to finding reputable installers of aerials etc.

In particular, the Switchover Help Scheme is available to those who are:

Aged 75 or over; get or could get disability living allowance, attendance allowance, constant attendance allowance or mobility supplement; have lived in a care home for six months or more; are registered blind or partially-sighted

Chief Inspector Nigel George said: "Dyfed Powys Police wish to emphasise there should be no cold-calling by people purporting to be installers, and anyone facing such callers can telephone the police for further help or guidance on 101. I would also wish to ask the public in general, and in particular neighbours, friends or families of the elderly and vulnerable to be vigilant and report any suspicious people and/or their vehicles to the police again on 101."

If you have not received the booklet or need further information on the switchover - contact Digital UK on 08456 505050.
