London purchase for a China-based investor — source-of-funds clearance on CNY-denominated capital
A Shanghai-based business owner wanted to purchase a London flat as a long-term investment. His deposit — held across ICBC and Bank of China accounts in mainland China — generated extensive source-of-funds queries from both the lender and the UK conveyancer. We managed the documentation process and completed the purchase within the agreed timeline.

The Situation
Our client was the director of a manufacturing and export business in Shanghai, generating CNY-denominated income from domestic Chinese trading activity. He had identified a two-bedroom flat in East London at £490,000 as his first UK property investment. His deposit of approximately 35% of the purchase price was held across two mainland Chinese bank accounts — one with ICBC and one with Bank of China — and had been accumulated over several years from trading income and director's drawings from his company. He had no UK credit history, no UK bank account and had not previously purchased overseas property. His visa was a standard visitor visa.
The Challenge
Source of funds is consistently the most intensive documentation challenge for mainland Chinese buyers. UK anti-money laundering requirements — applied by both the mortgage lender and the UK conveyancer separately — require clear, documented evidence of how the deposit was generated and accumulated. For a CNY deposit held in Chinese domestic banks, this involves: Chinese bank statements (requiring certified translation where the originals are in Mandarin), Chinese tax returns or business accounts demonstrating the income source, documentation of any SAFE-regulated cross-border transfers (China's State Administration of Foreign Exchange controls capital outflows), and a clear audit trail from the Chinese account to the UK conveyancer client account. Each layer of this chain requires documentation, and the process for compiling it correctly — so that it is accepted without delay by both the lender and conveyancer — is not widely understood in the standard UK mortgage market. The visitor visa position also limited the lender panel to those who accept non-resident buyers.
Our Approach
We identified specialist lenders with a documented process for mainland Chinese buyers and source-of-funds documentation in CNY, and whose legal panel was experienced in handling the conveyancing side of the SAFE transfer chain. We worked with the client and his Chinese accountant to compile the full source-of-funds package in advance of the lender submission: three years of company accounts demonstrating the trading income from which the deposit had been accumulated, the client's personal Chinese tax returns for the same period, ICBC and Bank of China statements covering 12 months, certified translations prepared by an accredited translator, and a clear narrative explaining the SAFE framework and the permissible capital export route for the transfer amount. We coordinated directly with the conveyancer on the AML documentary requirements so that the same evidence package satisfied both the lender and the legal team without duplication of requests to the client.
The Outcome
Mortgage offered at 65% LTV through a specialist lender with genuine international capability. The source-of-funds documentation was accepted by both the lender and the conveyancer without further requests once the initial package was submitted correctly. The SAFE-regulated transfer from the Chinese accounts cleared through to the conveyancer client account and the purchase completed on the agreed date. The client is exploring a second UK investment property.
