Legally, you can do any work you like on your own gas boiler, provided you are competent to do so. The law doesn't specify any particular qualifications to be "competent".
All this is immaterial now. got local quote for new boiler, fitting etc hopefully fitting in the next couple of day. getting priority because of illness and no real heating. Thanks to all who commented

More specifically it's illegal to install your own gas boiler (or any other gas appliance) as it has to be registered and upto building regs.
DIY gas work is legal provided that you are competent - following regulations, you do not need to be registered to work on your own appliance. You must be registered to work on anyone else's appliance however, and if your work causes damage to anyone else's property, you could be sued. If it causes death (eg. via explosion) then you could be facing manslaughter charges. So typically you wouldn't do it.

Competent does require specific certification depending on the work being done plus being gas safe registered.

Which law says that?
Which law says that DIY work can't be signed off as complying with building regs?
If it breaks, well it wasn't working right anyway.
