Bank of Dave: Money to Burnley

What can we learn from one man's attempts to set up a bank of his own?

9pm on Channel 4 tonight sees the first episode in a two-part documentary called Bank of Dave. It follows Burnley businessman David Fishwick as he attempts to open his own bank to serve the people and businesses of his home town.

The programme will undoubtedly provide more than a few salutatory lessons for British banks. I know this, not because I have been fortunate to witness an early screening but because I have read David's book Bank of Dave: How I Took on the Banks, which chronicles his endeavour.

David’s attempt at setting up a bank and turning a profit in 180 days is fascinating, and makes one wonder whether we need more Banks of Dave. I think we do.

The total start-up costs for Dave’s bank, including premises and equipment, were £9,000 and his weekly overheads came to £396. Some will argue that Dave’s costs are not indicative of what is required, and in some respects they are right. Banks probably need more than one laptop and a couple of notebooks. Even then, Dave shines an unforgiving light on the high overheads, including inflated salaries and cumbersome, out-dated IT systems, that burden many British banks.

Dave also shows that nowadays banks no longer have a monopoly on the services they provide. Dave's bank does almost everything a high-street bank does: it makes loans, takes deposits and even makes investments in property, stocks and shares. But because he wasn’t granted a banking licence by the FSA he can't call his bank a "bank" or say that he takes "deposits".

Increasingly people are choosing to avoid banks when accessing financial services. Dave himself gets advice from Giles Andrews, CEO of peer-to-peer lender Zopa. The government and regulators should not stand in the way of innovation and regulators could do more to ensure that people feel confident using new financial services that meet appropriate standards.

Dave’s most important insight, and this comes on page one of the book, is that "all banks are about people". This is something forgotten by many of Britain's large banks. Dave meets the people he lends money to, and he knows the property he invests in. His decisions are based on more than just credit scores or the value of the security. A bank that adopted Dave’s practices would have lower default rates, higher customer satisfaction, and greater ability to cross-sell products to loyal customers. The recent growth of Metrobank and Handselsbanken in Britain is testament to this.

The Bank of Dave not only casts many of Britain’s banks in a dim light but, perhaps inadvertently, it also demonstrates one of the inherent weaknesses in our banking system. Dave promises to guarantee every deposit in his bank with his own money. He also makes it clear that "we wouldn’t be lending what we hadn’t got", not leveraging the assets of his bank.

In these two respects Dave’s bank is relatively unique, and therein lies the dilemma. People want security but many also want leverage with the risk and reward this entails. Regulators would love it if all deposits in every bank were guaranteed by their owners but this would come at a price. Leverage and debt is now a sin under the government’s austerity drive but one of the commonest criticisms of the banks is that they are not lending.

In preparing to set up his bank, Dave meets David Buik, a market analyst, who tells him: "you’re not going to stop the banking system blowing up from time to time". Dave disagrees; his bank would be 100 per cent guaranteed. As Britain looks to reform its banking system it would do well to learn from Dave, but some of the lessons may be harder to swallow than others.

Inside Big Ben: why the world’s most famous clock will soon lose its bong

Every now and then, even the most famous of clocks need a bit of care.

London is soon going to lose one of its most familiar sounds when the world-famous Big Ben falls silent for repairs. The “bonging” chimes that have marked the passing of time for Londoners since 1859 will fall silent for months beginning in 2017 as part of a three-year £29m conservation project.

Of course, “Big Ben” is the nickname of the Great Bell and the bell itself is not in bad shape – even though it does have a huge crack in it.

The bell weighs nearly 14 tonnes and it cracked in 1859 when it was first bonged with a hammer that was way too heavy.

The crack was never repaired. Instead the bell was rotated one eighth of a turn and a lighter (200kg) hammer was installed. The cracked bell has a characteristic sound which we have all grown to love.

Big Ben strikes. UK Parliament.

Instead, it is the Elizabeth Tower (1859) and the clock mechanism (1854), designed by Denison and Airy, that need attention.

Any building or machine needs regular maintenance – we paint our doors and windows when they need it and we repair or replace our cars quite routinely. It is convenient to choose a day when we’re out of the house to paint the doors, or when we don’t need the car to repair the brakes. But a clock just doesn’t stop – especially not a clock as iconic as the Great Clock at the Palace of Westminster.

Repairs to the tower are long overdue. There is corrosion damage to the cast iron roof and to the belfry structure which keeps the bells in place. There is water damage to the masonry and condensation problems will be addressed, too. There are plumbing and electrical works to be done for a lift to be installed in one of the ventilation shafts, toilet facilities and the fitting of low-energy lighting.

Marvel of engineering

The clock mechanism itself is remarkable. In its 162-year history it has only had one major breakdown. In 1976 the speed regulator for the chimes broke and the mechanism sped up to destruction. The resulting damage took months to repair.

The weights that drive the clock are, like the bells and hammers, unimaginably huge. The “drive train” that keeps the pendulum swinging and that turns the hands is driven by a weight of about 100kg. Two other weights that ring the bells are each over a tonne. If any of these weights falls out of control (as in the 1976 incident), they could do a lot of damage.

The pendulum suspension spring is especially critical because it holds up the huge pendulum bob which weighs 321kg. The swinging pendulum releases the “escapement” every two seconds which then turns the hands on the clock’s four faces. If you look very closely, you will see that the minute hand doesn’t move smoothly but it sits still most of the time, only moving on each tick by 1.5cm.

The pendulum swings back and forth 21,600 times a day. That’s nearly 8m times a year, bending the pendulum spring. Like any metal, it has the potential to suffer from fatigue. The pendulum needs to be lifted out of the clock so that the spring can be closely inspected.

The clock derives its remarkable accuracy in part from the temperature compensation which is built into the construction of the pendulum. This was yet another of John Harrison’s genius ideas (you probably know him from longitude fame). He came up with the solution of using metals of differing temperature expansion coefficient so that the pendulum doesn’t change in length as the temperature changes with the seasons.

In the Westminster clock, the pendulum shaft is made of concentric tubes of steel and zinc. A similar construction is described for the clock in Trinity College Cambridge and near perfect temperature compensation can be achieved. But zinc is a ductile metal and the tube deforms with time under the heavy load of the 321kg pendulum bob. This “creeping” will cause the temperature compensation to jam up and become less effective.

So stopping the clock will also be a good opportunity to dismantle the pendulum completely and to check that the zinc tube is sliding freely. This in itself is a few days' work.

What makes it tick

But the truly clever bit of this clock is the escapement. All clocks have one - it’s what makes the clock tick, quite literally. Denison developed his new gravity escapement especially for the Westminster clock. It decouples the driving force of the falling weight from the periodic force that maintains the motion of the pendulum. To this day, the best tower clocks in England use the gravity escapement leading to remarkable accuracy – better even than that of your quartz crystal wrist watch.

In Denison’s gravity escapement, the “tick” is the impact of the “legs” of the escapement colliding with hardened steel seats. Each collision causes microscopic damage which, accumulated over millions of collisions per year, causes wear and tear affecting the accuracy of the clock. It is impossible to inspect the escapement without stopping the clock. Part of the maintenance proposed during this stoppage is a thorough overhaul of the escapement and the other workings of the clock.

The Westminster clock is a remarkable icon for London and for England. For more than 150 years it has reminded us of each hour, tirelessly. That’s what I love about clocks – they seem to carry on without a fuss. But every now and then even the most famous of clocks need a bit of care. After this period of pampering, “Big Ben” ought to be set for another 100 or so years of trouble-free running.
