There are several ways that you can deal with this.
If you are happy to deal with it yourself, you can do so and you can apply to court either for the cost of the materials to do the job offer in order for what is called specific performance to make them give you the materials.
You could apply to court for an order for specific performance of rectifying the job to compel them to do it.
You could get the work done by a professional Tiler and take the developer to court for whatever its cost you to have it done professionally.
If you are issuing court proceedings, you have to tell the developer in writing that unless they do whatever it is you want to your remedy, and do it by a particular date (say 15 days hence) you will take them to court without further notice.
The reason I would suggest that you either bought the materials yourself and pursued them for the cost you got a professional to do it and then pursue them for the costs is because this could easily take 10-12 months to get to court and meanwhile, you are left with the unsatisfactory tiling.
If you are buying the materials, I would just buy them from a recognised supplier but do get a receipt. If you are going to get a professional tiler to do the job, get three quotations. Please note, quotations not estimates, because court judges do not like estimates.
Incidentally, the statutory provision is a breach of the Sale of Goods Act if the house completed before 1 October 20150 the Consumer Rights Act thereafter. The goods (the house) are not of satisfactory quality and that applies to both statutory provisions.
Can I clarify anything for you?
