N-New Build

@Dunc Self builders wouldn't need a New Home Warranty (the link you have posted) a Self Build Warranty should not have a 2 year defect period, Protek do provide Stage Release Certificates upon requests, it is not automatic as the stages change from lender to lender.

Have you tried Protek?

That's great if you do not require a warranty now, or feel it is not necessary, but what if you re-mortgage later on or decide to sell the property and the new purchasers lender requires a warranty?

A Professional Consultant Certificate is backed by Professional Indemnity Insurance Policy, Professional Indemnity Insurance claims can only be made as a result of proving negligence, which is very difficult to prove and often result in expensive legal fees, this is why so many lenders do not accept a PCC, on the basis that they give neither the mortgage or the mortgagee real protection, my understanding is also that PCC's are also not FCA regulated. @MJamesW is correct, there are companies dressing up a PCC as a 10 Year Warranty, which it is not and this shouldn't be allowed. There are lots of companies that can provide a Structural Warranty quotation, such as Self Build Zone, Protek, Build Warranty, backed by "A Rated Insurers" that are regulated and have lender approval, maybe also take a look at the reviews online to get a good idea of who you are dealing with before committing the ££s

They are probably just establishing the risk, for instance, has the site been inactive for a long period of time? Is the property water tight? Etc It’s a fair question, if you want the right policy.
