We have had five - in 1976!
From the excellent Trevor Harley:
The summer of 1976 was exceptional in containing 5 consecutive days above 35C.

Interesting though that the max was "just" 35.9C...
I think he is mistaken there. In his page for 1976 he says that there were five 35C+ days in the whole heatwave, but they weren't consecutive.
And looking at the date records from Torro for June:
23 |
32.2 |
90.0 |
Maldon (Essex) 1976 |
24 |
32.4 |
90.3 |
Gillingham (Kent) 1976 |
25 |
33.5 |
92.3 |
East Bergholt (Suffolk) 1976 |
26 |
35.4 |
95.7 |
North Heath (W Sussex), East Dereham (Norfolk) 1976 |
27 |
35.5 |
95.9 |
Southampton-Mayflower Park 1976 |
28 |
35.6 |
96.1 |
Southampton-Mayflower Park 1976 |

Camden Square (London)1957 |
|
35.0 |
95 |
Northolt (London) 1957 |
30 |
33.3 |
92.0 |
East Malling and Swanley (both Kent) 1957 |
The 25th certainly wasn't. 26th to 28th were 35C+, but then the 29th isn't mentioned (you'd think if it did reach 35.0C it would be mentioned as the tied for second place below the dubious Camden Square one.
And the 30th clearly wasn't either, so there can't have been more than four in a row even if the 29th was.
I need to find the official Met report for 1976.
The Monthly Weather Report for June 1976 says: "In London temperatures exceeded 32C on every day from the 25th to the 28th, the first time that this value has been reached in London on four consecutive days for at least 135 years".
I'm pretty sure that a mere 32C has been reached on more than four consecutive days at least once since then!
