It is possible. It may be simple though, maybe when the tech was there he went to your settings on speedtest.net and changed your preferred server to something that gave a more favorable result.
So everyone can see your results before you signed up >> https://testmy.net/compID/179936226875
You should definitely run some multithread speed tests like Sean suggested and test against the UK test server to get a full picture.
Welcome aboard
I would suggest trying a multi-threaded download test to see what speed you get: https://testmy.net/multithread
Place a tick mark next to your nearest server and leave the rest unchecked, e.g. if you're in the UK, tick 'London' only and then click 'Test my Internet'
If you get a faster download result, then it is quite likely your ISP is either only able to handle about 1Mbps per connection or is limiting individual connections to this rate. Speedtest.net performs a multi-threaded test. TestMy does not have multi-threaded uplink test, at least not at this time.
