Porting with current lender
- Retains existing rate and avoids early repayment charges when conditions are met.
- Lender still reassesses affordability and property suitability.
- Useful when rate remains competitive and timelines are tight.
Home Mover Guide
How should home movers balance porting, switching, and timing?
Written and reviewed by Sophie Harrison · Page last reviewed 8 May 2026
Successful movers manage two transactions at once: redeeming or porting the existing mortgage while securing finance for the new property. 42% of movers switched lender in 2024 when the blended rate or borrowing requirement made it cost effective (UK Finance Mortgage Trends Q4 2024).
How do home movers manage the end-to-end journey?
Plan the process in parallel streams so the sale and purchase remain synchronised.
- Request a redemption statement and confirm porting eligibility at least 60 days before marketing your property.
- Obtain an Agreement in Principle for the onward purchase and share it with estate agents.
- Align completion dates and identify whether you need temporary financing to cover gaps.
- Submit full applications for both ported elements and new borrowing once offers are accepted.
- Coordinate valuations, surveys, and legal work for both properties to avoid fall-throughs.
- Prepare funds for deposit differentials, stamp duty land tax, and moving expenses before exchange.
Where should home movers source their mortgage?
Compare incumbent lender retention deals with external remortgage offers and niche building society criteria.
Switching to new lender
- Unlocks fresh incentives such as cashback or free valuations.
- Creates one coherent mortgage instead of multiple sub-accounts.
- Requires full legal process and careful timing to avoid double payments.
Execution-only and direct options
- Only suitable for simple chains and borrowers confident in product selection.
- Brokers often secure quicker lender escalations when issues arise, which can save chains.
- Consider direct channels only if your circumstances and property types are straightforward.
Which product options do movers compare?
Evaluate products holistically across cost, flexibility, and chain management.
- Ported sub-accounts paired with top-up borrowing on new rates from the same lender.
- Two or five-year fixed rates with fee structures optimised for the expected move frequency.
- Offset mortgages for movers holding significant savings during the transition period.
- Tracker or discounted variable rates when early repayment is likely after selling another asset.
How is affordability tested for movers?
Lenders revisit affordability in full, even for ported borrowing.
- Income reassessment includes basic salary, variable pay, and rental or investment income.
- Existing mortgage conduct is scrutinised; arrears typically push cases to specialist lenders.
- Stress tests assume higher repayment rates, especially when borrowing increases.
- Childcare, commuting, and maintenance commitments are updated to reflect the new property.
How do lenders treat equity and deposits for movers?
Equity released from the sale forms the primary deposit, but lenders still verify provenance.
Sale proceeds
- Provide memorandum of sale, redemption statements, and solicitor confirmations showing net proceeds.
- Maintain funds in a UK solicitor or client account ready for exchange.
Supplementary funds
- Document personal savings or gifts using the same standards as first-time buyers.
- Bridge finance or short-term loans require explicit disclosure to avoid breaching lender policy.
What credit signals matter for home movers?
Strong credit conduct differentiates between porting approvals and manual underwriting.
- Lenders expect clean mortgage payment histories and minimal unsecured arrears.
- High credit utilisation during the moving process can trigger recalculations; keep balances stable.
- Specialist lenders can accept historic blips but often require higher deposits or fees.
- Use soft-search tools for Agreement in Principle checks to avoid multiple hard footprints while comparing options.
What readiness checklist reduces chain risk?
Timeline management
- Create a dual timeline showing sale and purchase milestones with responsibility owners.
- Book surveys and valuations early to avoid chain-wide delays.
- Maintain weekly check-ins with solicitors, agents, and brokers.
Financial preparation
- Retain contingency funds to cover overlapping mortgage payments if completion dates slip.
- Review protection policies to ensure cover aligns with the new mortgage balance.
- Document additional borrowing purposes with quotes or invoices for renovations.
Which data points inform your strategy?
- Average time between instruction and completion for home movers: 14 to 16 weeks (HomeOwners Alliance Home Moving Study 2024).
- Average equity released by movers in 2024: GBP 153,200 outside London and GBP 269,700 in London (Zoopla UK House Price Index 2024).
- 71% of movers ported at least part of their mortgage when early repayment charges exceeded 1.5% of the balance (Intermediary Mortgage Lenders Association 2024).
- Mortgage fall-through rates averaged 23% in 2024, driven primarily by valuation issues and timeline slippage (TwentyEA Homemover Report 2024).
