The company’s portfolio has been independently valued at £135.6mln as at 30 September, up from £124.6mln at the end of March.
The NAV per share edged up to 278p per share, up a penny from six months earlier. The company is expecting to see most NAV growth in the second half of the current fiscal year.
Contracted rental income growth in the six-month reporting period rose by 7.2% to £8.2mln from £7.6mln, driven by the letting of space in the company's redevelopment and refurbishment pipeline.
Management's work on further refurbishments is on track to commence in the next few months and is expected to deliver an uplift in returns, Circle said.
"During the first six months of this year we have been highly active in creating a pipeline of well-located, income-generating assets to complement our portfolio, which are expected to provide significant upside and deliver strong NAV growth over the full year,” said John Arnold, the chief executive of Circle Property.
“The regional office market remains structurally strong and our active management of our property portfolio, alongside the negotiation of new existing lettings, continues to generate market-leading returns. Having established this momentum, we look forward to the full year ahead with confidence,” he added.
