Meet the Fredericks: A Growing Family in Putney

The Fredericks (name changed for privacy) had lived in their three-bedroom Putney home for five years. With two young children and nursery fees climbing, their household budget was under pressure. Their mortgage deal, a five-year fixed rate taken in 2020 was about to end. They were worried about:

  1. Rising interest rates
  2. Moving onto their lender’s Standard Variable Rate (SVR)
  3. Monthly payments jumping by several hundred pounds

The Challenge

Their existing lender’s renewal offer would have increased their repayments by almost £400 per month. The family wanted a more affordable option but also needed:

  • Certainty: A fixed rate for the next few years
  • Flexibility: The ability to make overpayments when their income allowed
  • Speed: Their current deal expired in just six weeks.

Our Approach

As independent mortgage advisers in Putney with 30 years experience, we took these steps:

Full Mortgage Review: We analysed the Fredericks’ current loan, outstanding balance and future plans.

Market Research: We compared deals from dozens of lenders, looking for competitive fixed-rate options with reasonable fees.

Negotiation & Application: We liaised with the chosen lender to secure a decision in principle quickly, ensuring there was no break between their old and new deal.

The Result: £300 Saved Every Month

Within two weeks we had secured a new five-year fixed rate at a significantly lower interest rate than their lender’s SVR.

This meant that the Fredericks were paying £300 less in monthly repayments, an annual saving of £3,600. It also meant that they had peace of mind knowing their rate is fixed until 2030. The mortgage product that we helped them to secure allows up to 10% overpayments each year without penalty, meaning that they had flexibility to overpay their mortgage if they chose to.

“We were dreading the jump in payments,” Mrs Fredericks told us. “But Oliver and the team at Oportfolio handled everything and kept us informed at every step. Now we can plan our finances with confidence.”

Key Takeaways for Putney Homeowners

  • Don’t wait for your deal to expire. Start exploring remortgage options at least six months before your current rate ends.
  • Independent advice matters. Whole-of-market brokers can access deals you might not find directly.
  • Check the fine print. Features such as overpayment allowances can make a big difference long-term.
