The pubwiki site lists the pubs which have existed over the past two hundred years, or so. The site only lists pubs which can actually be referenced, and proven as having existed, rather than random claims like these.

Which is the oldest inn in England?
Claim is made for the Chandos Arms, Edgware, just closed after an existence of over 800 years. But that is likely to be disputed, on behalf of a number of other taverns - notably the Popes Head, Norwich. The Saracens Head, Newark. The Old Green Man, Erdington, and the Bell, Finedon, the records of which date from the eleventh century. The strongest of all the claimants to the honours would seem to be the Fighting Cocks, St Alabns, which claims to be not only the oldest inn but the oldest inhabited house in England.
It is a curious structure of octagonal design, and is believed to have been originally built as a boat house of the monastery founded at St Albans by KIng Offa in 795 - "Liverpool Post".

The "Chandos" and "Masons Arms"
The 900 year old "Chandos Arms" at Edgware, which had been associated with Dick Turpin, the Duke of Chandos, and the old coaching days, is to go and it will reappear as a modern house at Colindale. Its neighbour the "Masons Arms" is to be pulled down and rebuilt when the corner of Whitchurch lane is widened. At the annual licensing meeting for the Gore Division of Middlesex were heard.

The Old and the New.
The oldest tavern in England, with the exception of one at Chester, has been turned into a booking office for motor coach travellers. It is the Chandos Arms, Edgware, one of the old coaching houses, which, it is said, dates back to the days of William the Conqueror. Tradition has it that a back room was used by Dick Turpin.
In the next room is an imposing marble fireplace, which used to have a home at Canons, a large house at Edgware, built by the first Duke of Chandos. Handel, who lived for two years at Canons, was a frequent visitor at the old tavern.
There was a time when the Watneys and Truman pubs were being sucked into the empire of the Grand Metropolitan
Watneys (Red Barrel, which was later an appalling beer) and Trumans (slightly better beer) were purchased by the Grand Metropolitan chain. Apparently, Grand Metropolitan closed down the good breweries and sold even more appalling beer to the detriment of the brands.
The wiki states that Grand metropolitan bought the Truman, Hanbury & Buxton chain in 1972, and next Watney Manns; plus a host of other drinks related businesses including J & B Whiskey. The problem was in 1989, Lord Young decided to cut the brewers monopoly, by reducing their size to 2,000 but in essence to sell off half of all pubs over the number of 2,000 by the year of 1992. The wiki covers most of this detail, and I will not repeat it here, but this is a list of about 500 Grand Met pubs in 1991 just prior to selling off to Charringtons - these are in London and also the South East (Hertfordshire, Kent & Essex).
You can research the 1939 electoral register at findmypast by address only, which is excellent. This register does not give masses of detail, but it does have a date of birth for a person, which is invaluable for proper searching of other records. Their services, are available, at a monthly or annual charge; or for free at a local library.
Stepping back in time again, we step back about 30 years to the 1940s and the World War, when great swathes of London and the South East were harangued by the war time bombing, and masses of London was demolished by the V1 and V2 rockets. About the same time, streets were being renamed to remove the repetition of road names. I list each and every pub and beer house in 1944, and this is a very useful guide in researching back further. This pub history site largely covers pubs and beer houses in 1944 and the two hundred years earlier - including their street name changes along the way.
One point I always make is NOT to exclude the beer retailers. many of these were, and continued to be off licences. Other beer retailers are now the well known pubs that we have known forever (apparently).
My article on research of a pub will start to
explain the differences between the different areas of London and the South
East, and why some areas had lots of pubs, and some had none. I know that modern
press is always going on about the numbers of pubs that have closed, as many are
sold off for housing, and often in very desirable areas. The modern pub is
getting bigger, e.g. the Wetherspoons, and relies on food to make a decent
living. This is also matched by a change in where pubs proliferate, and you will
also see find that many newer pubs were previously banks, or other commercial
buildings, which have been re-invented as the modern pub; whilst the older, and
smaller pubs close.
