Thanks for the source. I was indeed going by the OPs experience and hadn't looked into the actual cost myself.
Here's the US link as well:

The battery replacement costs are about halfway down the page. It says $199 for a battery replacement on a 13" or 15" Retina MacBook Pro. It also says "The final service fee we charge will be determined during testing. Pricing and terms vary for service through an Apple Authorized Service Provider."
It sounds like the OP might have better luck going through Apple directly (if there are no Apple stores nearby, perhaps he can ship them the computer). It also leads me to believe that there may be an issue with something in addition to the battery that the OP isn't aware of.
OP, did you receive any info regarding diagnostics / tests that were performed on the MacBook Pro? While you only brought the computer in for a battery replacement, perhaps they found some other problem and the price quote you were given included some additional repair costs.
Anyway, if I'm not missing anything and those prices are indeed accurate, $199 (while still higher than it should be) is a bit more reasonable.
The MBP has not actually been seen by anyone either from Apple or an authorised service centre. I have merely told them that the trackpad is FUBAR'd and needs replacing.
I know full well there is nothing else wrong with the MBP. The battery has less than 100 cycles and the keyboard and top chassis is immaculate.
As I already said, I contacted the authorised service centres where I got the quotes from (all in the 400-450 GBP range) and said could I not just submit the MBP for a battery replacement @ 159 GBP. As expected, they said no as the battery has to fail diagnostics in order to be allowed to be replaced under the battery service program.
I would just like to make clear to those who are arguing against what my issue is with all of this. I fully understand why Apple build the new laptops like this, and I am sure that other manufacturers do or will do the same. I get that they design these obscure batteries and glue them to a million other components to extend battery life and save weight and space etc. Plus as others have said, I get that there are 'environment' benefits to how they do it.
I get it.
What I also get is that Apple is in the business to make money, and as others have said, there are certain situations where once any Applecare warranty has expired, if a component fails and it is going to cost nearly as much to replace the part as it would to replace the computer, then win win for Apple.
But if this is the future of how laptops are built, where does it end? Will it come to a point where they make them in such a way that if your trackpad fails, you have to replace practically everything in the machine except the screen?
And to those who keep going on about buying Applecare. Applecare does not cover accidental damage. Yes my original fault was something that would have been covered by Applecare, I get that too. I thought I was not covered by any kind of warranty anymore, with the MBP being 15 months old (now I realise the UK has some additional statuatory rights that I was not aware of). Anyway - if we imagine that the fault had been caused by myself in the first place, accidentally or caused by misuse, the fact still remains that I damaged ONE component, and yet I am expected to pay for PERFECTLY WORKING COMPONENTS THAT ARE NOT DAMAGED.
I have no issue paying for the damaged component + labour. But replacing the entire top case and other components that are not related to the trackpad damage and expecting the individual... the individual who maybe saved up for months to buy the laptop in the first place and cannot **** money for fun to pay for 1/3 of a new MBP... it is just not right. Sledge hammer to kill an ant is the phrase that springs to mind.
I will end by saying this:
1. I didn't realise that even though I was outside the 12 months Applecare period, I still had rights in the UK and could have probably got the faulty trackpad for free.
2. I didn't realise that the trackpad was not a component that could be replaced without replacing a whole segment of the laptop. Had I known this, I wouldn't have tried to fix it myself and therefore accidentally causing the glass coating on the pad to crack.
3. My lack of understanding of these 2 facts have landed me in a situation where I am more than likely going to have to find a way to pay the obscene repair costs. But I don't agree with it and if one person reads this and avoids the same traps I have landed in then good for them.
I am going to the Apple store on Tuesday to see if I can get a cheaper deal direct through them. Fingers crossed.
