The average salary across IT jobs is now £36,092 (US$54,859), according to IT recruitment firm CV Screen. It analysed 60,000 job advertisements in the first quarter of this year.
But CV Screen said there was "high demand" for developers of Microsoft SharePoint, .Net, and PHP scripting. Those developers earned average salaries of £42,357, £34,881 and £29,577 respectively.
Oracle developers earned an average of £39,517, while developers for the web earned £30,958. C# developers earned £35,125 and C++ developers £38,724, and Java developers £35,752. Graduates entering software development had an average salary of £24,016.
In networking, Cisco network support staff earned £32,933 and network managers had an average £40,692 salary. For open source staff, Linux systems administrators had an average salary of £36,198.
SAP consultants earned £52,684 on average, while Oracle DBAs earned £43,912.
First line support staff earned £19,523 and desktop support staff had an average pay of £26,554.
Matthew Iveson, one of the authors of the report, said: "It is clear that demand for IT professionals has fallen dramatically, and with unemployment rising we have found that candidates are now being more realistic with their salary expectations."
"There are some bright spots where demand remains strong especially for candidates with strong .Net, SharePoint, Java or PHP skills."
He expected salaries to stay low for the next 12 to 18 months, until "confidence returns to the industry".
IT jobs were again in the firing line today, as for this year, and insurer Legal & General said it was cutting 560 processing staff.
