What is the average Bank of England base rate since 1975?

The time-weighted average Bank Rate between January 1975 and July 2026 is 6.11%. By decade the averages run 10.77% for 1975 to 1979, 11.70% across the 1980s, 7.85% in the 1990s, 4.33% in the 2000s, 0.50% through the 2010s and 2.74% in the 2020s so far.

That single figure does more work than the whole chart. A borrower comparing a quote today against the rate they paid in 2021 is comparing it against the most abnormal decade in the entire record. Compared against the 51-year average, the current level is below it, not above it.

The decade averages also show why the 2010s distort every intuition formed in them. At 0.50%, the 2010s average is roughly one twenty-third of the 1980s average. Nobody who took their first mortgage between 2009 and 2021 has any lived experience of what the series calls normal, and lenders' affordability stress tests exist precisely because the Bank knows that.

What is the highest the Bank of England base rate has been?

Bank Rate peaked at 17% on 15 November 1979, a single three percentage point rise from 14% on the day, and that remains the largest one-day increase in the series. The floor came 41 years later at 0.10% on 19 March 2020. The full range across five decades is 16.9 percentage points.

The 1979 peak was less a policy failure than the price of ending a decade in which inflation had run out of hand. It is the useful read for a borrower, because it shows what the Bank is willing to do when its inflation target is genuinely threatened. The base rate is an instrument for one job, holding consumer price inflation at target, and the level required to do that job has varied enormously across the historical interest rates the UK has actually lived through.

The largest cuts in the series are smaller than the largest rise. Bank Rate came down two full percentage points twice, on 25 November 1980 and again on 11 March 1981, and by one and a half points on 6 November 2008 as the financial crisis broke. Rates go up in bigger single steps than they come down in. The 2021 to 2023 sequence was the modern illustration.

The near-zero decade, 2009 to 2021, was the outlier

Bank Rate fell to 0.50% on 5 March 2009 and did not rise above 0.75% until December 2021, twelve years and nine months later. It sat unchanged at 0.50% for 2,709 consecutive days, the longest hold in the series, and there was no change at all in the six calendar years from 2010 to 2015.

The path through that window is worth setting out, because it is the period almost every current borrower formed their expectations in. Bank Rate was 0.50% from March 2009, 0.25% from August 2016, back to 0.50% in November 2017, 0.75% in August 2018, then down to 0.25% and 0.10% within eight days in March 2020. Across twelve and three quarter years the highest it ever reached was 0.75%. Nothing else in the history of the Bank of England base rate looks remotely like it.

What followed was fast rather than extreme. Fourteen consecutive increases between December 2021 and August 2023 took the rate from 0.10% to 5.25%, where it stayed for a full year before the first cut in August 2024. Borrowers experienced that as a shock because they measured it against the preceding decade. Measured against the chart's full range, 5.25% was unremarkable, and it sat below the 51-year average throughout. The shock was the speed, not the destination. Anyone who came off a cheap fix mid-sequence and did not start remortgaging early enough felt it twice.

How often does the Bank of England base rate change?

There is no fixed rhythm. The Monetary Policy Committee meets eight times a year and most meetings end in a hold, but before the MPC existed in 1997 the rate moved far more freely. Bank Rate changed 36 times in 1982 alone. It changed six times across the whole of 2016 to 2021 combined.

A change takes effect on the day it is announced, which is why the line steps rather than slopes. Between decisions the rate is fixed, whatever inflation data or market pricing does in the meantime. The 1982 figure is not a data error: under the pre-MPC regime the rate tracked money market conditions and was reset repeatedly, eight times in August of that year alone.

Clustering matters more than frequency. Once the Committee starts moving in one direction it rarely stops after a single step, because it is responding to an inflation picture that takes months to turn. Fourteen rises in a row on the way up, then a measured sequence of quarter-point cuts on the way down. If you hold a tracker mortgage, the question that matters is not whether one meeting delivers a change but whether a run has begun, which makes the date of the next Bank of England meeting the first thing to check.

What does base rate history tell you about fixing now?

The record cannot tell you where the rate goes next. It does tell you the range is wide and that moves arrive in runs, so the decision that matters is the length of your fix and the early repayment charge attached to it, not an attempt to time a single Monetary Policy Committee meeting.

Three product types respond to the base rate differently, and the history argues differently for each. Tracker rates move with Bank Rate directly, so the run pattern in the chart is a live description of your payment risk. Fixed-rate mortgages are priced off sterling swap rates, which reflect expectations rather than the current level, so a fix can reprice in a month when Bank Rate has not moved at all. The standard variable rate is set at each lender's discretion, influenced by the base rate but not tied to it.

For where the market currently expects Bank Rate to head, our market-implied base rate projection sets out the SONIA-derived path in detail. For what lenders are charging today rather than what the Bank has done historically, the current UK mortgage rates page carries the fixed averages, and the UK mortgage rates chart tracks them by loan-to-value band. Comparing total cost across the whole lender panel rather than one balance sheet is the job of a whole of market mortgage broker. History sets the context. Your horizon, your deposit and your tolerance for payment change set the answer.

FAQs

1. What is the Bank of England base rate history?

Bank Rate is the Bank of England's official policy rate, and the Bank's published record of it runs back to 1694. The chart and table on this page cover January 1975 onwards, a span of 258 separate changes. Across that period the rate has ranged from a 17% peak in November 1979 to a 0.10% low in March 2020.

2. What is the average Bank of England base rate?

The time-weighted average between January 1975 and July 2026 is 6.11%. By decade it runs 10.77% for 1975 to 1979, 11.70% in the 1980s, 7.85% in the 1990s, 4.33% in the 2000s, 0.50% in the 2010s and 2.74% in the 2020s so far. The 2010s figure is the outlier, not the benchmark.

3. What is the highest the UK base rate has ever been?

17%, effective 15 November 1979. It arrived as a single three percentage point rise from 14%, the largest one-day increase anywhere in the series, and it was the Bank's response to double-digit inflation. Double-digit Bank Rate was routine through the late 1970s and much of the 1980s rather than a one-off emergency setting.

4. What is the lowest the UK base rate has ever been?

0.10%, effective 19 March 2020, at the start of the pandemic. It had been cut from 0.75% to 0.25% only eight days earlier, so the rate more than halved twice inside a fortnight. That 0.10% level held for 637 days until the first rise in December 2021.

5. How many times has the Bank of England base rate changed?

258 times between 20 January 1975 and 18 December 2025. Of those, 85 were increases and 172 were reductions. The pace is wildly uneven: 36 changes in 1982 alone, against no change at all in the six calendar years from 2010 to 2015.

6. What has the base rate done over the last 20 years?

Set the chart to 20Y to see it. The window opens shortly before the 2008 financial crisis, covers the fall to 0.50% in March 2009 and the long stretch below 0.75%, then the fourteen consecutive rises to 5.25% between December 2021 and August 2023, and the cuts that followed from August 2024.

7. Will mortgage rates ever go to 3% again?

Nobody can know, and any answer is an expectation rather than a fact. What the record shows is that the sub-1% base rate era ran from 2009 to 2021 and was unlike anything in the preceding three centuries. Mortgage pricing follows swap rates rather than Bank Rate directly, so fixed pricing depends on where markets expect rates to settle across the term, not on any single decision.

8. Does a mortgage broker help when the rate outlook is uncertain?

Yes. The value is not in predicting Bank Rate, which nobody does reliably. It is in comparing total cost across lenders and terms for your actual case, checking the revert rate you would fall onto, and timing the application so an offer is in place before your current deal ends. Mortgage One does that across the whole intermediary-accessible lending market.
