The normal advice applies:
- Always ask for identification before letting anyone you don't know into your house.
- Check credentials, including a permanent business address and landline telephone number. The mobile phone numbers given on business cards are often pay-as-you-go numbers which are virtually impossible to trace.
- Take control by asking the questions. Ask for references from previous customers or to see examples of their work.
- Don’t sign on the spot – shop around. Get at least three written quotes to make sure you’re not being ripped off.
- If in any doubt, ask the person to leave or call Citizens Advice on 03454 04 05 06.
- If you’re suspicious, why not ask the salesman if you can take their photograph – on your mobile phone, for example? If the person is legitimate, they probably won’t mind.
The bottom line is that a genuine salesman has nothing to hide and will always be prepared to call back. And if it sounds too good to be true, it usually is.
