It depends on what you have done, The standard Kit bumper bonnet wing ends wing mirrors and Bumper IS £450 retail plus Vat BEFORE club Discount if done here in Grantham. The full coverage frontal kits are more but we are covering the whole of the car forward of the A Pillar
You could just have the Bumper done for instance (however still leaves you with potential damage to the other areas) also as it is designed to be there for four years it will work out cheaper than having smart repairs every year (and a lot cheaper than a respray every year).
Smart repairs typical costs for example usually end up about £120 in my experience for most multiple repairs and they will never look perfect and need re-done every year.
Hope that helps
