The reliable way to hire a tradesperson

Noticed one of the dry verge caps is sticking out slightly from the lower side, are they able to be pushed in easy enough, do they clip in to the joining verge cap, its the 5th one up from the start

I’ve recently had my garage converted which involved new lights and sockets throughout the existing garage and also having a new consumer unit fitted for all the new and existing electrical connections in the house. I’ve received my electrical certificate and under description of installation it states ‘garage conversion socket/lights’ and under extent of the installation it states ‘sockets/lights’. There’s no mention of the new consumer unit anywhere on any page of the certificate. Please could somebody confirm if the consumer unit install should be listed as well as the sockets and lights install? Any help very much appreciated

Is it possible to install a staircase for a loft conversion (bungalow) before the work upstairs starts? Reason is i want the stairs in to finish off the downstairs part before moving onto the loft next year. Obviously I won't be able to use them without the dormer above for head height etc and I have a separate loft hatch for access, but would like to fit them if only temporarily. Thanks
