Most people do not think about remortgaging until their fixed rate is about to end — and by then they are often already too late to do it calmly. I have watched friends fall onto their lender's standard variable rate for months while they got organised, paying hundreds of pounds more per month than they needed to. The process is not complicated, but the timing matters enormously, and the 2 vs 5 year fix question genuinely requires some thought in the current environment.
This is the guide I wish I had had when I first remortgaged — what to do, when to do it, and how to think through the decisions. The caveat throughout is that this is not financial advice. Mortgage decisions are significant enough that speaking to a whole-of-market broker — especially now, when the rate environment is genuinely uncertain — is worth the time even if you end up making the same choice you would have made anyway.
When your fixed rate ends, your lender automatically moves you onto their Standard Variable Rate. SVRs are currently running at around 7-8% for most lenders. On a £200,000 mortgage, the difference between a 4.5% fix and an 8% SVR is roughly £450 per month. Six months on the SVR while you get organised is £2,700 wasted.
The solution is simple but requires discipline: start the remortgage process 3-6 months before your deal ends. Most mortgage offers are valid for 3-6 months from the date of issue. This means you can secure a new rate now and complete the switch when your current deal finishes — without paying an early repayment charge or rushing.
Most people remortgage when their deal ends. But sometimes it makes sense to exit a fix early, even paying the early repayment charge to do so.
The maths: if you are on a 4.9% fix with two years remaining and your ERC is 2% on a £200,000 balance — that is a £4,000 exit cost. If the best new 5-year fix is 4.2%, you would save approximately 0.7% per year on £200,000, which is £1,400 in year one. After fees you are ahead in around three years and significantly ahead by the end of the new deal.
Whether this makes sense depends on the size of your ERC, the rate differential, and how long you plan to keep the new deal. In the current environment where rates have moved significantly compared to deals taken out in 2021-2023, this calculation is worth running if you are more than a year away from your deal's natural end and rates have moved substantially in your favour since you fixed.
This is the question I get asked most often about remortgaging and I want to give a direct answer, with the appropriate caveat that it is a personal perspective rather than financial advice and depends heavily on your circumstances.
Before the Middle East conflict escalated in early 2026, I would have leaned toward a 2-year fix for most people — the expectation of rate cuts made the shorter deal attractive. The calculation has changed. With the Bank of England holding at 3.75% in April 2026, one MPC member voting for a hike, and inflation ticking back up to 3.3%, the near-term rate cut story has been pushed back significantly.
My current thinking — not a recommendation — is that a 5-year fix at around 4.35% (best available for lower LTV borrowers as of May 2026) offers certainty for long enough to be genuinely restful, at a rate that is historically not unreasonable. If rates fall significantly in the next two years, you will pay slightly more than you would have on a 2-year fix. But if rates stay flat or rise, you will look very sensible. The insurance value of certainty, particularly for people with tight monthly budgets or young families, is real.
The 2-year fix at around 4.45-4.64% costs slightly more now and gives you the option to remortgage again in 2028 at whatever the prevailing rate is. If you believe rates will fall materially in the next two years — which is no longer the consensus view — this is the better bet.
I would not recommend a tracker in the current environment for anyone who cannot comfortably absorb a 1-1.5% rate rise in their monthly budget. The BoE's own scenarios include a hike, and Huw Pill's dissenting vote signals the direction of risk. See our full fixed vs tracker analysis for more detail on this.
Here is the practical process, broken into stages:
My honest answer is: use a broker, particularly in the current market. Whole-of-market brokers have access to deals that are only available through intermediaries and not direct from lenders. They also handle the paperwork, chase solicitors when needed, and give you someone to call if something goes wrong. They are paid by the lender, not you — so fee-free brokers genuinely cost you nothing.
The one scenario where going direct makes sense is if you are doing a product transfer with your existing lender — staying with the same lender and simply switching to a new deal. Product transfers are simpler, often faster, and your lender will offer these directly. They may not always be the most competitive rate, but they require no new affordability assessment and are worth getting as a benchmark before comparing elsewhere.
A mortgage application does leave a hard search on your credit file, which can temporarily lower your score by a small amount. This is normal and expected — lenders understand this. The impact is minimal if you are only applying to one or two lenders and typically recovers within a few months.
Using a broker for a soft search first — which does not leave a mark on your file — lets you see likely eligibility before committing to a full application. Most reputable brokers offer this.
