As Bob Hoskins said in the BT advert, a long time ago, "it’s good to talk"
It was good to talk to you.
It was my pleasure to assist you. Please come back if anything else crops up and needs clarification.
Thank you for trusting us with your legal problem.
As I said, you need to write to the landlady (email is fine) telling her that you have now taken legal advice and you have been advised that she is negligent for not having the wiring checked on a regular basis and accordingly she has until X date to pay up as per the quotations failing which you will issue Small Claims Court proceedings without further notice.
The new Moneyclaim beta system is easy to use: https://www.gov.uk/make-money-claim
the new system is much better than the old government Gateway system.
You can prepare the proceedings now, at your leisure, save them, and then just pay the fee and press the button when the deadline in your letter before action, expires.
It's then just a case of following the court process and responding to any emails that you receive.
Court fee is based upon the value of the claim:
The full list of court fees are here:

there is very little legal aid available now except in very few categories but if you are on benefits or low-income, you may get help with or not have to pay the fees. Details are here:

Thank you for letting me assist you with your legal question. I am glad that I was able to help.
I am not certain whether that answers the question for you or not, but I am happy to answer any specific points arising from this.
It will be my pleasure to help you again either further with this or any future questions you have
Kind regards
Stuart
