Where it lies is no longer an easy one to answer... about 2/3 of the fleet are currently being reconfigured with a MUCH reduced max CE load, and thus the squash happens sooner on some aircraft.
There are currently 3 planes which are not going to be converted. G-TTOA which is going back to the leasing company on 17 April. G-TTIC/D are basically going to stay as they are - mostly operating out of LHR on the AGP route, and the Moroccan nightstop (RAK/CMN).
All of the other aircraft are going to be converted throughout the winter...
New Config G-TTOB – G-TTOJ (A320's)
Club (Max) - 20 (Rows 1 to 4)
Economy with max club - 143
Max Economy - 168
Emergency Exits (Restricted Seats) Rows 11 & 12
Seats with no Recline - Rows 10, 11 & 28
New Config G-TTIA/B/E (A321's)
Club (Max) - 25 (Rows 1 to 5)
Economy with max club - 173
Max Economy - 204
Restricted Seats - 8 BC DE, 9 ABC EF, 22 ABC DE, 23 BC DE, 24 ABC DEF
Seats with no Recline - Rows 8, 22 & 35
So, I make 10A on an A320 a seat with no recline in normal ET seat pitch (if you are on a new converted aircraft)

Or if you are in one yet to be converted then row 10 will be an emergency exit... but am sure you would have said if you blagged one of those ?!
Albeit not for a few months, but bear in mind that there is also this addition to the GB fleet...
Boeing 737-800 x 1 - 1 May to 27 October
The 738 is damp leased from Excel with 189 seats in a two class configuration.
The club cabin is minimum two rows and maximum five rows with two seats each side (not sure about the pitch tho - however, 189 seats on a 737... that's the same number as our A321's pre-conversion!).
The leased 738 will operate the following programme from Gatwick
Day 1 - Faro and Las Palmas
Day 2 - Malta and Funchal
Day 3 - Malta and Heraklion
Day 4 - Paphos and Heraklion
Day 5 - Malta and Tenerife
Day 6 - Funchal and Heraklion
Day 7 - Tenerife and Mahon
