Coventry BS and Atom Bank Cut Limited Company BTL Rates: What London Landlords Should Do Now

What Has Changed?

Coventry Building Society has cut its limited company buy-to-let (BTL) mortgage rates by up to 0.2% on two- and five-year fixed deals. Atom Bank has also reduced its prime mortgage rates by up to 0.25% across various loan-to-value (LTV) bands. These adjustments offer more competitive borrowing options for landlords using limited companies, a common structure for portfolio and HMO landlords.

Why Does This Matter for Landlords?

Mortgage costs are a significant ongoing expense for landlords. Even a 0.2% reduction can lead to meaningful savings over the mortgage term, improving cash flow and potentially increasing net returns. For limited company landlords, who typically face higher borrowing costs than individual buy-to-let borrowers, these cuts help narrow the gap.

Impact Across Different Landlord Profiles

  • Portfolio Landlords and HMOs: Those with multiple properties held in limited companies stand to benefit most. Lower rates on two- and five-year fixes support longer-term financial planning and stability.
  • Single-Unit Limited Company Landlords: Even landlords with just one property in a limited company can reduce monthly mortgage costs, easing profit margin pressures.
  • Accidental Landlords: Many accidental landlords do not use limited companies; therefore, these rate changes may not apply directly. However, Atom Bank’s cuts on prime mortgage rates could benefit those with personal buy-to-let mortgages.

Practical Steps to Take Immediately

  1. Review Current Mortgage Deals: Identify when you can remortgage or switch products without penalties.
  2. Contact Your Mortgage Broker or Lender: Discuss the new rates and request tailored quotes based on your portfolio and borrowing needs.
  3. Run Cost-Benefit Analysis: Weigh potential savings against any fees or early repayment charges to decide if switching is worthwhile.
  4. Update Financial Planning: Incorporate the new rates into your cash flow forecasts, rent pricing strategies, and tax planning.
  5. Communicate with Letting Agents: If refinancing affects rent pricing or investment plans, keep agents informed to manage tenant expectations.

Benchmarking and Due Diligence

While these headline rate cuts are promising, actual savings depend on factors like LTV, credit profile, and product availability. If specific product details are unclear, consult brokers or use comparison tools specialising in limited company BTL products.

Looking Ahead

Stay alert to lender announcements as the market remains competitive, with potential for further rate adjustments. Regular mortgage reviews are essential in effective portfolio management.
