Hello my name is ***** ***** I am happy to help you today. Did they give you a timeframe when you made the order to have the kitchen done?
Ok so there is no issue that they accept responsibility for the flooring?
Ok you need to send them a letter before action to say that if the repairs are not complete within a certain timeframe (say 14 days) you will be left with no alternative but to have the work done else where and pursue them for your losses in connection with putting the work good in the County Court. Under the Supply of Goods and Services Act you have the right to expect that the work is of a reasonable quality and is fit for purpose. If it is not then you can bring a claim. Obviously they do not dispute that they need to do the work but should not keep you hanging on for ever and a day. You can also contact trading standards and get a reference number.
Hopefully taking such steps will encourage them to put matters right without you needing to do this.
If you have any further questions please do ask. lf I have answered your question I would be grateful if you would take the time to rate my answer. Thank you and all the best.
