301 Redirects Showing As 307 Redirects

[Webpresence]

Hi,

Our clients are adamant that they have set up 301 permanent redirects on their websites, but when we check using Screaming Frog and various online HTTP status code checkers they are showing as 307 temporary redirects.

Examples;
http://www.lifestylelifts.co.uk/home-lifts/ 
http://www.terrylifts.co.uk/

Again, the client says they are seeing 301 redirects. Why are we seeing 307's? Who is right?

Very puzzling, any theories would be very much appreciated

Thanks in advance.

Lee.
