Some tests for possibly dodgy websites:
TEST 1: Is the name address of the company (or individual) that registered the domain name shown on Nominet's 'Whois' service?
Answer: No. It's been hidden, thus breaking the rules on the registration of .co.uk business domain names.
Result: TEST FAILED
Test 2: Is there a geographical address for the company shown on the firm's website, as required by UK law?
Answer: No. The only means of contact is via a web form.
Result: TEST FAILED.
Test 3: Are the images showing the company at work here
http://kitchenforsale1.co.uk/about.php
actually real photos of their staff going about their business?
Answer: No. The image which appears to show one of their kitchen fitters at work can also be found on a Brazilian website. The other images are clearly 'stock' images too.
Result: TEST FAILED.
Hmmm. When my numbers come up on the National Lottery, so that I can order a nice new kitchen, I think that I'll be looking elsewhere ;-)
