A UK strategy consultant running his practice through a Swiss GmbH from Seefeld, Zurich, was buying a Grade II listed Lakeland cottage in Hawkshead as a holiday let with reserved personal-use weeks. The case ran four narrowing filters at once — holiday let, listed building, overseas limited-company self-employment, and two-currency household income — and the structural answer was a 70% LTV mortgage on the specialist holiday let panel.
Background
The client was a UK-born strategy consultant in his early forties, several years settled in Seefeld, Zurich, operating through a Swiss GmbH on a CHF salary and dividend allocation. His wife ran an independent freelance practice on USD income from US technology clients.
The property had come through an agent the family knew in the area: a four-bedroom Grade II listed Lakeland cottage near Hawkshead at £825,000, freehold, of the kind that sits at the centre of holiday letting demand inside the Lake District National Park. The household had taken the holiday let decision with their accountant, including the post-April-2025 tax position, before the case came to us.
What needed to happen
The brief was a 70% LTV holiday let mortgage: £577,500 of borrowing against an £825,000 freehold purchase, capital and interest, five-year fix, with personal-use weeks reserved within the lender’s product rules.
The complication was the combination of filters running in parallel. Holiday let appetite is a narrow part of the lender market on its own. Listed-building appetite narrows it further. Non-resident self-employment through an overseas limited company narrows it further still. And two-currency household income with a freelance share narrows it again. With all four applied at once, the high-street route was not in the conversation.
How we worked the case
Lender selection was the first piece of work. The specialist holiday let panel narrowed to the lenders comfortable underwriting all four filters together: holiday let with reserved personal-use weeks, listed-building permitted on a Grade II Lakeland cottage, non-resident self-employment through a Swiss GmbH, and two-currency household income with a freelance share.
The income evidence pack was built across both earners before the application went in. On the GmbH side, three years of Swiss GmbH accounts with accountant certification, the salary-and-dividend split documented, and a twelve-month CHF-to-GBP exchange-rate analysis to support sterling-denominated affordability. On the freelance side, two years of US-client invoicing, the underlying tax filings, and forward-pipeline letters from the practice’s principal clients. UK lenders apply a haircut to both currencies, and that haircut was modelled in advance.
The holiday let income projection came from a regulated Lake District holiday letting agent, set out as low, mid, and high week assumptions anchored to comparable cottages in the Hawkshead and Coniston area. The lender’s interest-cover ratio test was run at the applicable stress rate for the product, with personal-income top-slicing held in reserve as a contingency on a subset of the panel. A specialist RICS valuer with listed-building experience was instructed.
Expert Insight: “Holiday let mortgages are underwritten on a regulated agent’s income projection at the lender’s stress rate, not on AST rental cover. Get that projection right, anchored to genuinely comparable properties, and you have the foundation of the application. Get it wrong and the rest of the structuring does not save you.” Justin Whitelock, Founder of Mortgage London
Outcome
The mortgage offer was issued and completion achieved on a five-year fix with a specialist holiday let lender, at 70% LTV with the listed building permitted, Swiss GmbH self-employment recognised, and two-currency household income accepted with the standard haircut applied. The property was let through a Lake District holiday letting agent from completion, with personal-use weeks reserved within the lender’s product rules.
Key takeaways
- Holiday let mortgages are underwritten primarily on holiday let income projection at the lender’s stress rate, not on AST rental cover. The regulated agent’s low, mid, and high week assumptions do the underwriting work, and the projection has to anchor to genuinely comparable properties to stand up.
- Self-employment through an overseas limited company is recognised by part of the specialist panel where the company accounts, accountant certification, and salary-and-dividend split are presented to UK lender standards before the application is submitted.
- Grade II listed buildings narrow the lender list further, and a specialist RICS valuer with listed-building experience is part of the sequencing rather than an afterthought once the application is live.
