Mortgage Rates Explained: Fixed vs Variable

Choosing between a fixed and variable rate mortgage is one of the most important decisions you’ll make — and one of the most misunderstood. There’s no universally right answer. The best choice depends on your circumstances, your risk tolerance, and what’s happening in the wider economy.

We help clients across Birmingham, Solihull, and Tamworth make this decision every day. Here’s what you need to know.

Fixed Rate Mortgages

A fixed rate locks in your interest rate for a set period — typically 2, 3, or 5 years, though longer fixes of 7 or 10 years are available.

What you get: Certainty. Your monthly payment stays the same regardless of what happens to interest rates. If rates rise, you’re protected. Your budgeting is simple.

The trade-off: If rates fall, you don’t benefit. You’re locked in. Most fixed rates come with early repayment charges (ERCs) — typically 1-5% of the outstanding balance — meaning you’ll pay a penalty if you want to switch or redeem the mortgage during the fixed period.

When it suits: Fixed rates suit people who value certainty and budget predictability. If you’re stretching to afford payments, a fixed rate removes the risk of rate rises making your mortgage unaffordable. First time buyers often gravitate toward fixes for the peace of mind.

Variable Rate Mortgages

Variable rates move up and down, meaning your monthly payments can change. There are several types.

Tracker mortgages follow the Bank of England base rate at a set margin. If base rate is 4.5% and your tracker is base rate plus 0.75%, your rate is 5.25%. When base rate moves, your rate moves by the same amount. Trackers are transparent — you know exactly why your rate changes and by how much.

Standard Variable Rates (SVR) are the lender’s default rate — what you revert to after a fixed or tracker deal ends. SVRs are almost always more expensive than other products and can change at the lender’s discretion. Staying on SVR is rarely a good idea, which is why we always contact clients before their deal expires.

Discount variable rates offer a discount off the lender’s SVR for a set period. They’re variable because the SVR can change, and your rate moves with it. Less transparent than trackers because SVR changes are at the lender’s discretion.

How to Decide

Consider your budget sensitivity. If a 1-2% rate increase would make your payments uncomfortable, fix. The certainty is worth the potential cost of missing out if rates fall.

Consider the rate environment. When rates are low and expected to rise, fixing locks in the low rate. When rates are high and expected to fall, tracking lets you benefit from reductions. The trouble is nobody knows with certainty what rates will do — economists get it wrong regularly.

Consider your plans. If you move, remortgage, or make overpayments within the next few years, ERCs on fixed rates could be costly. Variable rates typically have fewer restrictions.

Consider the term. A 2-year fix gives you flexibility to reassess soon. A 5-year fix gives you longer certainty but locks you in for longer. We’re seeing more clients choose 5-year fixes recently for the extended stability.

What About Rate Predictions?

We get asked constantly whether rates will go up or down. The honest answer is nobody knows for certain. We can look at market expectations (swap rates price in where the market thinks rates will be), Bank of England guidance, economic indicators, and inflation trends. But these are indicators, not guarantees. We share our view with clients and explain the factors, but we’ll never tell you we know what rates will do — because we don’t. What we can do is structure your mortgage so you’re comfortable regardless of which direction rates move.

When Your Deal Ends

Whatever product you choose, it has an end date. When it expires, you’ll revert to the lender’s SVR unless you remortgage onto a new deal. We contact every client before their deal expires to discuss options. In most cases, switching to a new product — either with the same lender or a different one — saves significant money compared to staying on SVR.

Our Recommendation

We don’t have a blanket recommendation. Fixed rates suit some clients, variable rates suit others, and the right answer changes with market conditions. What we always recommend is making an informed decision based on your specific circumstances — not following what your mate did or what a newspaper article suggested.
