Certifying documents in Switzerland
UK lenders may ask for copies to be certified, for example by a Swiss notary. German, French or Italian documents may need certified translation. Requirements vary, so confirm the acceptable certifier, wording and validity period before arranging certification.
Timing and next steps
Payslips, statements and address evidence can expire during an application, so gather them close to the application date. A complete overseas case commonly takes around six to ten weeks (indicative only). See our UK mortgages for Switzerland expats page, the expat mortgages hub, the non-resident stamp duty guide and our currency hub for moving CHF to GBP.
