Difficult one but I think you will find that the supply into your meter box is the responsibility of the company that supplies your electricity eg Endesa or Iberdrola, whoever sends you a bill each month; there should be a customer service contact number on your bill. You need to stress to the supply company that the overhead cable is a severe health hazard. If you cant get any joy from them you should report the matter to your local Town Hall.
Just a point for the future; the builders supply that you currently have is, by law, a three year maximum contract and at the end of that period the contract will expire and unless your landlady sets up a new contract as a vivienda your supply could be cut off at some point during your tenancy.
This is exactly the situation we are currently trying to sort out; our builder (A Brit) walked off the job when we refused to pay him. He had quoted a price which we agreed and had paid in full; he then requested more cash to complete the job. Since not one room in the house was liveable we had little option but to pay up. The money we paid him was diverted onto another job and no further work was carried out on our property. He then came back to us and asked for yet more cash and when we refused he simply walked away, leaving us high and dry to complete the work ourselves.
Apart from the reform work, the original contract included obtaining the electricity bolletin and a certificate of first occupation. We were left on builders supply until a month ago when we had a call from Endesa advising that the obras contract for out electricity would expire at the end of November and that immediate action was required to set up a normal vivienda contract. We contacted an electrician who is licenced to issue a Bolletin, and he and a rep from Endesa visited the house to see what, if anything, was required before the bolletin could be issued.
The Bolletin is a prerequisite for setting up the new contract as is the Licence of First Occupation.
I contacted our local Town Hall re the licence and was advised that a) the original Planning Document authorising the planned work had not been paid for by our runaway builder and that b) an independent survey would be required before the Licence of First Occupation could be granted. The original bill was for 100 Euros but because it hadn't been paid it was subject to a 100% surcharge so I had to pay 200 euros into the local town hall account. The independent survey cost me another 250 Euros. I presented the survey report to the town hall this morning and was advised that the Licence would be sent to me in about a week.
The investigation by my electrician and Endesa revealed that since the original installation was carried out in 2006, additional work was required to comply with the latest laws concerning the supply of electricity. This additional work has cost me another 950 Euros... and we still run the risk of having our electricity cut off because of the delay in issuing the Licence.
The way things stand at the moment our chosen electrician is setting up the new contract with Endesa on our behalf and has been pretty much on the ball; he has a good reputation in our area.
Clearly at this time of year the last thing we need is for our Electricity to be cut off but it could still happen...
