Because it is usual for Genies to be the first to attend, they may only have commonly used parts to repair the problem straight away making sure you are safe.  Additional parts will be needed and a return to fit to get a more permanent fix.  The Genie should advise you what type of fix they are able to provide at the time.  A charge will still apply for their attendance, even if you choose not to accept their fix or advice.  For example there are many types of boilers all with their own differing parts, so one would need to be ordered once the Genie knows what is needed.  If you need more information about this, please do contact us.
