The north-south pay divide is narrowing for IT professionals after wages grew 29.7% faster in the north than in London in 2007.
Salaries grew by 4.8% in the north of England last year, while growth in the capital was limited to 3.7%. IT workers in the north currently earn 69% of London wages.
Northern IT workers now earn an average of £30,333 a year, compared with £44,200 in London.
The figures from Rethink Recruitment showed IT is bucking the national trend for all occupations, which saw a further widening between northern and London salaries of 2%.
The IT recruitment company said technology-utilising organisations were increasingly moving to the north as London gets more expensive and regeneration projects start to make the north more attractive.
Figures for 2006 showed a similar trend for IT salaries.
Although most highly paid frontline IT roles are still based in London, the north-south divide is expected to narrow further as organisations such as the Bank of New York, the Bank of Scotland and the BBC continue to invest in the region.
Jon Butterfield, managing director, said, "Technology-utilising organisations are asking why they need to be in London. Rising costs in the capital and advances in mobile and wireless technology are making relocation increasingly attractive.
"The IT workforce in London is highly dependent on the health of the financial services industry, but far less so in the north. The credit crunch may afford northern techies the opportunity to close the pay gap still further on their southern peers."
