Many thanks for your patience, I am pleased to be able to continue assisting with your query now. First of all, I am sorry to hear about the issues you have experienced in your situation.
Your understanding of your consumer rights is correct. Just to recap, when a consumer enters into a contract for services, the Consumer Rights Act 2015 says that such services must be:
- Carried out with reasonable care and skill (to the same standard as any reasonably competent person in that trade or profession)
- Finished within a reasonable time (unless a specific time frame has been agreed)
- Provided at a reasonable cost (unless a specific price has been agreed)
In addition, any information exchanged in communications between the parties, whether written or verbal, is binding if the consumer relies on it to proceed with the services in question. If there are problems and the trader cannot satisfy the above criteria, which are legally expected of them, the consumer will have certain rights
In the event of substandard work, the trader should either redo the parts of the work which are inadequate or perform the whole service again at no extra cost to the customer. This must be done within a reasonable time and without causing significant inconvenience. If this is not possible, the consumer can claim a price reduction, based on the severity of the issues. That is something which should be negotiated between the two parties. However, if the trader refuses to resolve the issues, the consumer can consider getting someone else to do this and either deduct these costs from the balance that is still owed to the original trader, or pursue them for any extra costs that have been incurred as a result.
When it comes to the threats of the builder, he can of course make them and even make a claim in court if he chooses to. That does not mean he will get anywhere though and the courts will look at the above principles when establishing whether you have any further liability, if any at all. In the circumstances you should maintain your position and not be intimidated by his threats, which often can be empty anyway – just a way tot ry and scare you into complying with his demands.
