BoE Base Rate vs Mortgage Pricing

The base rate is the number every headline leads with, but it is not the number your fixed mortgage is priced from. The chart on this page tracks it against average two and five year fixed pricing at 75% loan-to-value, so the gap where the real decision sits is visible. Mortgage One is a whole of market mortgage adviser that reads the margin between base rate and fixed pricing when timing a client's deal.

How much above the base rate do mortgage rates sit?

Fixed mortgage rates sit above the base rate by a margin the lender sets, not by a fixed or published amount. At 75% loan-to-value, the chart on this page plots that gap month by month, and it has widened and narrowed repeatedly in periods when the base rate itself did not move at all.

There is no separate mortgage base rate. The Bank of England sets Bank Rate, and every lender then prices its own products off it with a margin reflecting funding costs, risk and how hard it wants to compete that week. Two borrowers sitting behind the same base rate can be quoted rates a full percentage point apart on the same morning.

That is why the gap matters more than the level. The same base rate can sit underneath a cheap market or an expensive one, depending entirely on what lenders are adding on top of it. Watching the two lines on the chart converge or separate tells you whether lenders are absorbing risk into their margins or passing better pricing through to borrowers.

The 75% loan-to-value band shown here is a deliberate reference point. It is where most remortgaging homeowners actually sit, and it attracts mainstream lender pricing without the sharpest headline rates reserved for the lowest loan-to-value tiers. Rates in other bands move in the same direction but rarely by the same amount, and our UK mortgage rates chart plots each band separately.

Why fixed rates price off swap markets, not Bank Rate

A two year fix is priced from the two year sterling swap rate plus a lender margin, and a five year fix from the five year swap. Swaps reflect where markets expect Bank Rate to average across that whole term, so fixed pricing moves on expectations rather than on the decision itself.

Sterling swaps are the instruments lenders use to convert variable funding into a fixed cost for a set number of years. When a lender writes a five year fix it commits to a rate for sixty months while its own funding costs float, and the swap market is where it buys the certainty to do that. The swap rate is the raw material of a fixed mortgage in a way the base rate never is.

This is why fixed rates routinely move in months when the Monetary Policy Committee does nothing at all. A softer inflation print, a shift of tone in a speech, or a move in gilt markets can reprice the swap curve within hours, and lender repricing follows within days. It explains the opposite case too: a cut that markets had fully expected is already sitting in the swap curve before the announcement, so fixed pricing barely twitches when it lands.

The forward path of that curve, rather than the base rate as it stands today, is what our base rate outlook tracks.

Which mortgages actually move when the base rate changes

Only trackers move contractually with Bank Rate, applying a margin fixed for the deal term. Standard variable rates move at the lender's discretion and need not follow a cut at all. Discount deals sit a set amount below an SVR the lender still controls, so they inherit that discretion rather than escaping it.

A tracker is the only product where the link is written into the contract. If Bank Rate falls a quarter point, a tracker falls a quarter point with it and the lender has no say in the matter. Some trackers carry a collar, a floor below which the rate will not fall however far Bank Rate goes, and that clause is worth finding before you sign rather than after. Our tracker mortgage guide sets out the mechanics.

The standard variable rate is the opposite arrangement. It is a rate the lender sets and can change at any time, for any reason, whether or not Bank Rate has moved. Rises tend to be passed on quickly and cuts slowly, and nothing obliges a lender to do otherwise. Our standard variable rate guide covers why it is almost always the most expensive place a mortgage can sit.

A discount mortgage takes a set reduction off that same SVR, so it looks like a variable product but carries the lender's discretion inside it. Our discount mortgage guide explains how that differs from a tracker, and the distinction matters most in exactly the months when the base rate is on the move.

A fix, meanwhile, does nothing at all. Once the rate is set it is set, and Bank Rate can go wherever it likes for the length of the term.

What else moves your rate beyond the base rate itself

Your loan-to-value band, the product fee attached to the deal, the lender's funding position and its appetite for new business all sit between the swap curve and the rate you are quoted. Two lenders reading identical swap markets routinely produce different offers on the same case in the same week.

Loan-to-value is the largest single lever a borrower controls. Lender pricing steps down in bands, so moving from just above a threshold to just below it can be worth more than several months of market movement. If a valuation or a modest capital repayment would take you under the next band, that is the first thing to test. Our loan-to-value calculator gives you the figure before you apply.

Product fees distort headline comparisons badly. A fee-free deal at a slightly higher rate frequently beats a market-leading rate carrying a four figure fee, and where the crossover falls depends entirely on the loan size. On smaller balances the fee dominates the maths. On larger ones the rate does. Comparing the two on total cost across the fixed term is the only version of the comparison that means anything.

Then there is the lender itself. Funding mix, capital position, service capacity and whether it is chasing volume or protecting margin all feed into what it adds over the swap. A lender running hot on applications will widen its margin to slow the flow, regardless of what Bank Rate did that month. Our current two and five year fixed rates page shows how far apparently identical products can diverge.

Does a base rate cut mean a cheaper mortgage for you?

Not automatically. A cut passes straight through to a tracker, is applied at the lender's discretion on a standard variable rate, and does nothing to a fix already in force. On new fixed pricing, a cut that markets had already expected is usually in the swap curve well before it is announced.

The disappointment borrowers feel after a cut nearly always comes from the same misunderstanding. They watch the announcement, expect fixed rates to fall the following morning, and find that nothing has changed. Nothing has changed because the market moved weeks earlier, when the expectation formed rather than when the decision confirmed it.

The corollary is the more useful half. Fixed rates can fall meaningfully in a month when Bank Rate is held, if the data arriving during that month shifts expectations for the year ahead. Anyone waiting for a decision before acting is watching the wrong signal.

If you are already on a fix, a cut changes nothing until your deal ends. What it may change is the pricing available when it does, which is why the renewal window matters more than the announcement calendar. Our remortgaging guide covers how to weigh a product transfer against switching lender once that window opens.

Reading the base rate gap when you time your next deal

The useful signal is the margin over the base rate, not the base rate level. A wide gap means fixed pricing has room to fall without any decision from the Bank of England. A thin gap means further falls need Bank Rate itself to move, which is a slower and less certain bet.

In practice that becomes two questions rather than one. Is the base rate expected to fall, and is the margin over it wide or thin by recent standards? A wide margin alongside a stable base rate is the more forgiving position to wait in, because lender competition alone can close it. A thin margin with no cuts priced in is the position where waiting costs you.

None of that removes the case-specific work. The rate you are offered depends on your loan-to-value, income structure, credit profile and the fee you are willing to carry, and a whole of market mortgage broker looks at the products genuinely available to your case rather than at an average. The chart tells you what the market is doing. It does not tell you what you can get.

The discipline that works is to start the renewal review early and keep it under review, rather than trying to time an announcement. Settling the shape of the deal first, then watching pricing inside your own window, leaves you able to act when the market moves instead of reacting once it has.

To have the whole of market checked against your loan-to-value, fee tolerance and renewal date rather than against a market average, call 01202 155992 or contact Mortgage One.

FAQs

1. What is the mortgage base rate?

There is no separate mortgage base rate. The term usually refers to the Bank of England base rate, officially Bank Rate, which sets the cost of overnight borrowing between the Bank and commercial lenders. Every lender then prices its own mortgage products off it by adding a margin of its own choosing.

2. How much above the base rate are mortgages?

There is no fixed amount. The margin between the base rate and average fixed mortgage pricing changes constantly, and the chart on this page plots that gap at 75% loan-to-value so you can see where it sits and how it has moved. Individual quotes sit above or below the average depending on loan-to-value, fee and lender.

3. Do mortgage rates follow the Bank of England base rate?

Tracker mortgages follow it contractually, by a margin fixed for the deal term. Standard variable rates move at the lender's discretion and need not follow at all. Fixed rates do not follow the base rate directly, because they are priced from sterling swap rates that reflect where markets expect the base rate to average over the term.

4. What is the current mortgage base rate?

The current Bank of England base rate, alongside the current average two and five year fixed rates at 75% loan-to-value, is shown in the tiles beneath the chart on this page. Those figures update as new data is published, which is why they sit with the chart rather than in the body of this guide.

5. Who sets mortgage interest rates?

The Bank of England's Monetary Policy Committee sets Bank Rate. Individual lenders set mortgage rates. A lender's pricing decision starts from the relevant swap rate, then adds a margin reflecting its funding costs, capital position, risk appetite and how much new business it wants, so a mortgage rate is a lender decision rather than a Bank of England one.

6. What affects mortgage interest rates?

Swap rates do most of the work on fixed pricing, and they move on inflation data, growth data and market expectations for future policy. On top of that sit lender-specific factors and case-specific ones: loan-to-value band, product fee, income structure, credit profile and property type. The base rate is one input among several rather than the deciding one.

7. Will my mortgage payment fall if the base rate is cut?

If you are on a tracker, yes, by the amount of the cut. If you are on a standard variable rate, only if your lender chooses to pass it on. If you are on a fixed rate, your payment does not change until the fixed term ends. What a cut may change is the pricing available to you at renewal.

8. Can a broker tell me whether my rate is competitive against the current gap?

Yes. A whole of market broker compares the products genuinely available to your case, at your loan-to-value and with your income structure, against the market rather than against an average. That includes weighing a product transfer with your existing lender against switching, and comparing rate-plus-fee combinations on total cost over the fixed term.
