Superstar components, you can spec QR. Not sure how much they are currently, but they often have voucher code discounts.

looking they start around £240
Unfortunately everything bike related costs more than a year ago. £200 might not actually get you anything lighter or better unless you can find something lightly used. How heavy are they? Try some better lighter tyres?
Perhaps save a bit more and get new wheels for the summer?
Spa should be able to build you something reasonable for under £400 or maybe
@Beespoke can help?
