C Limited Company Mortgage
Ltd company BTL

Limited company buy-to-let mortgages.

Specialist BTL mortgages for UK SPVs and trading limited companies. Typical rates, deposit requirements, deal structuring.

In brief

UK limited company BTL mortgages are widely available via specialist lenders. Typical deposit 25%, rates 0.5-1% above personal BTL. Most lenders prefer SPVs (single-purpose property companies). Mortgage interest is fully deductible at the company level - no Section 24 restriction. Personal guarantees almost always required.

SPV vs trading Ltd - which one for BTL

Most BTL lenders prefer Special Purpose Vehicles - limited companies set up specifically to hold property, with SIC codes 68100, 68209, or 68320.

For a single property, the cost of incorporating an SPV (~£12 + £80-£150 to set up properly) is dwarfed by the rate savings over the life of the mortgage. A specialist accountant typically recommends SPV for BTL.

Typical Ltd BTL mortgage terms

ElementTypical range
Deposit25-40% (75-60% LTV)
Rate (5-yr fixed)5.5-6.5% (2025/26)
Arrangement fee1-2% of loan
Stress rate (rental cover)5.5-7.5% notional
Rental cover ratio125-145% of stress rate
Personal guaranteeAlmost always required
Stress rate is the rate your rent must cover - even if your actual mortgage rate is lower. So a £200K loan at 5.5% actual but 7% stress requires rent of ~£1,600/month minimum. A specialist broker calculates this upfront.

What you'll need to apply

FAQ

Frequently asked questions

How quickly can a Ltd BTL mortgage complete?+

Decision-in-principle usually within 1-2 weeks. Full offer 4-6 weeks after that. Completion 2-4 weeks after offer (subject to conveyancing). So 6-12 weeks end-to-end is typical.

Do I need a personal guarantee?+

Yes - almost always. Lenders want recourse to the directors personally because the company has no other assets. Specialist brokers know which lenders limit the guarantee scope (e.g. capped at the loan amount).

Can two directors apply jointly?+

Yes - very common. Both directors usually personally guarantee. Some lenders allow joint guarantees with each director liable for half; others require joint and several (each liable for the full).
