LONDON (Bloomberg) — Segro Plc, Britain's largest owner of business parks, plans to invest more in the UK this year once commercial property prices stop declining.

For the first time in four years, the company will acquire more real estate in the UK than it sells, chief executive officer Ian Coull said on a conference call yesterday. Segro, with assets including Slough Trading Estate, has £1.1 billion ($2.2 billion) available for acquisitions and developments.

"We are without doubt going to come back into the UK market," Coull said. "But we will withhold our firepower until we are confident the market has settled at the right level."

Owners of British offices, shops and warehouses last year had their biggest losses since 1990 as property values slid because transactions became more difficult and expensive to finance, the Investment Property Databank index showed. The UK accounts for about 79 percent of Segro's investments by value.
