^^^ That's the bike, eh? They cleaned it up pretty good.
Don't make the mistake of getting all unnecessarily tumescent about 105.
This Tiagra is as good / indistinguishable from 5700 105, it's not 11 speed, but then most people don't really need 11 speeds for the most part
Try actually riding them back to back, then comment. Technically what you said is true, practically speaking, not so much so.This isn't entirely true. 105 levers have a shift action that is the same as Dura Ace and Ultegra with a short throw. whereas the Tiagra has an older system that shifts heavier and has a longer throw. The same comparison can be made with the brakes, 105 has the same symmetrical twin pivot design found on the upper two models, not so with Tiagra that uses an older design that gives the brakes have a lack of feel and feedback through the levers, Tiagra also uses a one piece brake block so you cannot try higher end blocks and are stuck with getting Tiagra, and these blocks flex, plus it's more difficult to swap out the blocks. 105 Chainrings are reinforced for added stiffness over the Tiagra. The front derailleur...well not front mechanical derailleur shifts well, they never have. Rear derailleur wise 105 has a lighter spring balance and the shift is faster and smoother than Tiagra. 105 cassette is considerably lighter than Tiagra at almost 100 grams. the total weight difference between the two is about 350 grams which equates to about 12 ounces, or 3/4ths of a pound. Internally the mechanical bits and pieces of 105 has more in common with Ultegra then with Tiagra.
Now having said all of that, for the casual user Tiagra would be just fine. I have 105 components but I went with Ultegra rear derailleur, but I also went with Dura Ace 9000 cables which really made the 105 act and feel like Dura Ace, thus for a small amount of money it's possible you could improve the response of Tiagra by using DA9000 cables and make them feel like maybe 105.
Here is another option, it does come with disk brakes which I don't really care for, but if you ride in wet climate they are better than rim brakes under those conditions. http://www.wiggle.com/vitus-zenium-vr-disc-105-2017-road-bike/
2016 0 Defy (same bike renamed afaik) with Ultegra parts, £250 less and Shimano brakes (not the Tektros on the Contend)

Or the 1 for nearly £400 less

Looks like can do on C2W, albeit with a surcharge to cover the retailer fees

@roadrash bought the Defy 1 from Paul's iirc, after looking at the Contend
The Decathlon linked wasn't the most suitable for the OP's spec

I ride a slightly higher spec version of these and it's a great bike
