Firstly, I am amazed that Storey Homes are not signed up to the New Homes Ombudsman Service I couldn't see then on the register among the 500 housebuilders that are either active or "pending"
https://www.nhqb.org.uk/register-of-developers.htmlYou have been very patient and given them more than enough time to respond.
The NHBC will be another lengthy process, which may or may not be successful.
For anyone reading this post please see what buying a Storey New Home could mean for you!
"We Wont Forget You
We have a dedicated customer care team who are on hand to help once you have moved in. You can get in touch with our customer services team if you have any problems. We will also visit you once you have settled in to make sure you are happy."
The above statement taken from Storey Homes website! beware!
What to do?
Persist with the NHBC. Ultimately they can bring pressure on Storey Homes to fix the defects but I doubt that it will be done either quickly or properly.
Write to your local MP (he/she will want your vote next year!) as the New Homes Ombudsman should have been Statutory and therefore a legal requirement. What we have currently is an industry-led Ombudsman, yet it is still far better than the useless Consumer Code for Home Builders which should be gone by now.
Write to your local paper and the nationals. Defective new homes have gone off the agenda in recent years due to Covid and the goings on at Westminster, but defective new homes have not gone away.
Finally, you could post on social media. Twitter is good.
