Boiler & Cooker Registration (GCH cover)

labour216

Hoping someone can help me out with this:

Bought a leasehold flat in early 2008 – four flats within a large house that had been refurbished and sold on. The freehold is still owned by the person who sold the flats. Had a few problems within the flat which have been sorted very slowly such as poorly fitted windows, lighting, and drainage pipe for boiler not being insulated outside which resulted in a frozen pipe and not heating for which I had to make a claim against my own home insurance.
Recently want to get full GCH cover and was told the boiler needs to be registered, and at should have been at that time with CORGI. Found at the cooker and boiler are not registered; All I got when I got the flat was a buildings regulation certificate for completion of work from the council, and this isn’t sufficient to register the boiler. So now I’m chasing the original solicitors and specifically the seller to have this addressed at their cost.

Had a few questions:
- do I need to have the boiler/cooker registered if I want to sell (HIPS report etc), and do I have a legal claim against the original seller (or any other party) for not ensuring th cooker/boiler are registered (and also the fact they didn’t insulate the pipes outside which has affected my GCH indoors every since winter just gone)?

- I am considering taking the original seller to small claims court for not registering the cooker/boiler and also because the drainage pipe for the boiler outside was not insulated, which casused the frozen pipe this winter, for which I made a claim against my own home insurance and went without heating for a few day, does anyone know if this would be viable?

Thanks.
