Comparisons & scenarios
Last checked UK · illustrative onlyNot a lender or brokerAboutDisclaimer
Narrative UK remortgage comparisons that pair with our calculators — not stale rate tips. Use this Rodway Labs hub to decide which scenario page you need, what soft factors belong beside the numbers, and when a product transfer, a full remortgage, or a shorter versus longer fix is the question you are actually asking. Illustrative only — not personalised advice and not an FCA-regulated recommendation.
Why comparisons sit beside calculators
A calculator answers “what happens if these inputs are true?” A comparison page answers “which inputs matter, and which soft factors the spreadsheet will not show?” Remortgage Lab keeps those jobs separate on purpose. The remortgage vs product transfer calculator and the true cost calculator take editable figures. The child pages under this hub supply factor tables, re-fix risk framing, and EXAMPLE cues so you do not paste a rate gap into a decision without fees, early repayment charges (ERCs), underwriting friction and timing.
Fees and ERCs still come before rate-hunting here, same as on the costs hub. A retention deal that completes with low fees can beat a cheaper advertised remortgage you cannot obtain, or one that arrives after weeks of valuation and conveyancing. Independent context from MoneyHelper is a useful non-commercial starting point; your own offers and Key Facts Illustration remain the source of truth.
Remortgage versus product transfer
A product transfer (retention deal) moves you onto a new rate product with your existing lender. Underwriting is often lighter; fees are often low or nil; ERC usually does not apply if you time the switch at deal end. Rate choice is limited to that lender’s retention range. A full remortgage replaces the loan, usually with a different lender, and typically brings valuation, legal work and fuller affordability checks — with wider market access via broker or direct, and ERC if you leave the current deal early.
Open remortgage vs product transfer for the side-by-side factor table and short EXAMPLE cues. For definitions and process, use product transfer explained. For full two-column sterling maths on the shared EXAMPLE house, use product transfer vs remortgage EXAMPLE. If credit or income may be tight, ask whether a transfer that completes may beat a remortgage that stalls — that soft factor belongs next to any rate gap.
2-year versus 5-year fixed scenarios
Shorter fixes can look cheaper on day one but reprice sooner. Longer fixes buy payment certainty for longer — with a longer ERC window if you need to leave early (sale without porting, large overpay beyond allowance, and similar). Neither path is automatically better. A lower 2-year rate can still lose if each remortgage carries a four-figure fee stack, or if you drift onto a standard variable rate between deals. A 5-year fix can look expensive if you move home and face a long ERC, depending on portability and offer wording.
Open 2-year vs 5-year fixed for horizon framing and EXAMPLE cues. Sense-check monthly payments with the repayment calculator; fold fees and ERC into true cost. Timing around an ending fix is covered in fixed rate ending and rolling onto SVR. This hub does not predict Bank Rate or future mortgage pricing — paste your own quotes.
Soft factors the numbers understate
- Certainty and speed near deal end — retention often completes faster when the lender already knows the case; remortgage depends on valuation and conveyancing diaries. See how long a remortgage takes.
- Underwriting friction — self-employed income, recent credit events or complex ownership can favour staying put if a transfer is available. Framing only: credit and affordability when switching.
- LTV band moves — equity growth or a lower balance can open a better band on a remortgage that a retention menu may not match. Concepts: LTV bands explained.
- Overpaying versus switching — sometimes the better comparison is not lender A vs lender B but overpaying the current loan versus paying fees to move. See overpaying vs remortgaging and the overpay vs remortgage calculator.
How to choose a comparison page
- Fixed deal ending soon; retention letter in hand? Start with remortgage vs product transfer, then the matching calculator with your figures.
- Choosing deal length on a new product? Open 2-year vs 5-year fixed; count fee rounds and ERC exposure over a five-year mental horizon, not only month one.
- Need fee and ERC detail first? Switch to the costs hub — comparisons assume you already know those swing factors.
- Want editable maths only? Go straight to calculators; come back here when you need the narrative factor list.
Work a fair comparison in practice
Hold the horizon constant. Comparing two years of interest on a 2-year fix with five years of interest on a 5-year fix without adjusting for fee rounds or the second remortgage is a common trap. Likewise, comparing a retention pay-rate with a new-lender pay-rate without putting product, legal, valuation and broker fees on the same page understates remortgage cost. Put ERC on the page only when it still applies — if you complete after the charge end date, the line should be zero, not a ghost figure from an earlier quote.
Use the same balance, remaining term and cashback assumptions on both sides unless you have a documented reason to change them. The shared EXAMPLE house exists so articles and tools do not invent conflicting starter figures; replace every field with your offer before you treat an output as personal. If a broker or lender illustration uses different fee packaging (fee added to loan versus paid up front), mirror that choice in the calculator assumptions so the interest total stays honest. When two paths look close, soft factors — speed, underwriting certainty, portability — often decide, not a few pounds of monthly payment.
After you pick a narrative page, run the matching tool once with EXAMPLE figures to learn the layout, then again with your numbers. Keep a short written note of ERC end date, fee total, cashback clawback window and the comparison horizon you chose. That note travels better than a screenshot of a rate alone when you speak to an FCA-authorised adviser or revisit the decision a fortnight later.
EXAMPLE house cues used on comparison pages
Child pages reuse the shared labelled EXAMPLE case so sterling cues stay consistent: £185,000 balance, 22 years remaining, current EXAMPLE 4.19% with 4 months left, transfer EXAMPLE 4.39%, new-lender EXAMPLE 4.14%, fees to switch £1,499, cashback £250, EXAMPLE ERC 2% = £3,700 if you leave early, 24-month horizon. Scenario rates, not a market quote. Edit every input in the tools. Last checked: 2 November 2026.
