hmm.. may be UK spec is different with 2 special screws. Mine had just one phillips head screw in the coin box and the whole panel was held just by plastic clips.
I cant say for sure, but after you take off those screws, you should be good to unclip the panel under the steering column. I believe you have haynes manual, I hope you have the one for UK spec, because the screws may be different.
I do not see why would they put alarm in a different place than under steering column.

I just ordered a replacement remote for the alarm off ebay, because I bought it used and my car didnt come with the remote. I had purchased remote before and it didnt work with my car, I hope this one works. Once I get it I have to get under the dash and change it from auto to manual lock as well.

Good luck.

PS: may be the screws are torx screws. Just check the internet for the types of screws, you should get an idea what its called and buy the corresponding screw driver. I bought a tool box with different kind of screwdriver heads, wrenches, spark plug puller and everything. I would say you buy one as well, it comes in handy if you are a DIY person. It will cost you less a lot less in a long run than to buy individual screw drivers one at a time. Just my thought though.

 

It looks like the UK Accord uses what is called a cassette box stopper, UK Honda part number PFKL1014423 (U.S. Honda part number 91637-SD4-000). They may be Torx screws. If they are Torx screws, then you need a Torx driver. In the U.S, it is easy to get Torx drivers; I'm not sure about U.K.

Once the screws (er, cassette box stoppers; lol), it should only be held in with clips and/or hooks. Just do it slowly, if the plastic panel has hooks, that area of the panel needs to be lifted.
