For sure you will get much better sound over the wireless speaker with 1,5k£ 3.1 package.
What size of room you have and do you have tv at the middle of wall? Just making sure you don`t have some massive open plan room or corner tv etc. which makes things more difficult.
There is some good deals for speakers, but sadly the av-receivers costs are very high and we have to look something bit cheaper to fit in your 1,5k£ budget unless you willing up it slightly. Typically you do get some discount when you purchase speakers + amp etc. together so make sure you don`t go ordering anything blind, always negotiate. It´s a shame PT doesn`t have cheap stands so you need to buy them elsewhere.
You probably want to see some gear so let`s put popular option which most folks would enjoy in this price range.
The Monitor Audio Bronze 50 bookshelf loudspeaker is the most compact model in the series and delivers a size-defying audio performance.

Subwoofer you want to order from company that specializes in woofers to get best bang for buck, no matching requirements with speakers. With your tight budget BK Electronics would be the way to go. They have new grade-b models cheaper on their 2nd ebay site called Colosussxb, members for years haven´t found any marks on these and there is few models/finishes to look at depending how tight your 1500£ is and also how much you get discount from the speaker/receiver package. The subs comes with 2year warranty, spikes, cables etc. You can also order them for bit more on their main site which has more finishes if you looking something specific to suit your room decor.
If you require something narrow (~28cm) then look BK Double Gem. You can change the black grille to white too in the 2nd one. It looks quite large due to two drivers, but in reality it´s quite compact. I can show more pictures in room if this model intrests. There is few more and better ones though..

PR model:

For speaker wire you want some OFC and 2,5mm/AWG14. Hifi shops are going to rob you with the cable pricing and they always try to sell some big name stuff. You won`t hear any difference so spend your money wisely, this is long time favourite for many. 15meter roll easy to cut and cheap.
Amazon product ASIN B01C79XV5W
As you are newbie to this you could order the tool which has the AWG14 so with this it´s easy to cut and strip the wires, for 4£ only. Or you can use scissors with rounding movement (stripping the outer part away), youtube comes handy if you haven´t done this earlier.

Keep in mind you can go to local Richer Sounds listen any similar priced speakers i linked, they will surely have Bronze 50s there. Demoing is free and you don`t have to buy anything right away, you can ask package price for 3 speakers and X2700H. They typically let you compare 1-4 different models side by side, some require that you book demo time, but you can try your luck by going there if you live at neighbour..
