I have been asked to look at this for you.
The answer is extremely straightforward.
The garage owner has failed to carry out the job with reasonable care and skill and therefore is in breach of the provisions of the Consumer Rights Act 2015.
You are entitled to compensation/damages that would be the cost of getting the vehicle fixed properly pursuant to the damage which he caused and for the cost of a hire car while it’s being repaired.
You need to get a quotation (not an estimate) for fixing it and then present that to the garage owner telling him that’s what he is required to pay and give him a deadline.
He won’t pay so expect to go to the Small Claims Court.
www.moneyclaim.gov.uk is quick and easy. You can prepare the proceedings now, and save them online ready to issue them whenever a deadline expires.
You may find that once the court proceedings land on his doormat, he becomes more “cooperative” or you may find that he simply buries his head in the sand.

Please note you are not rating whether it’s favourable, because sometimes you may not get the answer you want, but basically my knowledge and way of dealing.
The thread does not close and I am happy to answer any questions you may have arising from this.
