⚡ Quick Answer
Variable rate mortgages move with the Bank of England base rate (tracker) or your lender's own rate (SVR/discount). With the BoE base rate at 4.23%, the best tracker rates start from 4.37% (base + 0.10%). They suit borrowers who expect rates to fall.
Types of Variable Rate Mortgage
- Tracker mortgage: Moves directly with the Bank of England base rate (e.g. base rate + 0.25%). When the base rate changes, your payment changes the following month.
- Discount mortgage: Set at a discount below your lender's SVR (e.g. SVR – 1.5%). Moves when the lender changes their SVR.
- Standard Variable Rate (SVR): The lender's default rate — set by the lender and can change at any time. Usually the most expensive option. Avoid unless you're planning to sell soon.
When Variable Makes Sense
If the Bank of England is in a rate-cutting cycle (as expected in 2025–26), a tracker mortgage benefits from each cut automatically — without remortgaging. The downside: if rates rise, your payment rises too. Most trackers have no ERCs, giving you freedom to switch to fixed any time. See the BoE base rate history ↗.

Frequently Asked Questions
- Loan-to-value bands (95/90/85/80/75%) drive pricing — check the nearest band boundary
- Start remortgage shopping up to 6 months before your fix ends — you can lock now and switch if rates fall
- Get a soft-search decision in principle first — it costs nothing and reveals problems early
- Whole-of-market brokers see deals comparison sites don't carry, especially for non-standard income
What Actually Moves the Needle
New-build purchases carry extra moving parts: developer deadlines (often 28 days to exchange), incentives that lenders may deduct from the valuation, and the need for extended offer validity. Tell your broker it's new-build on day one.
Product fees deserve as much attention as rates. A £1,499 arrangement fee on a lower rate beats a fee-free deal only on larger loans — roughly £150,000+ for typical gaps. Run both totals over the fixed period before deciding.
Timing your remortgage matters more than most borrowers realise. Most lenders let you secure a new rate up to 6 months before your current deal ends — if rates rise you're protected, and if they fall you can usually re-lock lower before completion.
