Ordered a 3-Phase Meter - it took more than 3months to be installed. Two initial installation appointments were made, engineers arrived, but were only qualified to install and brought single phase meters. The situation required me to make far in excess of twenty phone calls to try and organise the installation. Always had to go through the main SP phone number - could never speak to the same person, so had to give all the details each and every time. The SP system doesn't allow their operatives to provide a direct phone number, or email address, or confirm the conversation via email, or call you back. Requests for managers to call back were ignored in the beginning as was two emails I sent to SP's CEO. The whole system is set up to run customers around in circles and avoid accountability. Finally after two months of phone calling an installation manager admitted that had no 3-Phase meters in stock. Tried to switch to another provider, but once you have provided SP with your MPAN number they won't release it, so your stuck! Eventually after 4months of effort the required meter was installed by the only engineer qualified to install 3-Phase. He advised he was having to travel as far afield as London and that he'd had numerous 3-Phase meters in his works van for months! I finally received a phone call from SP to enquire if I was satisfied. I advised I was not having taken numerous days off work, paid for electricians to be unnecessarily on hand to connect up the supply, lost time starting the project etc. I was offered £25.00 compensation. To be fair SP did look into and pursue my comment concerning the wasted appointments with my electrical engineer, but frankly I was too busy and felt SP had already cost me sufficient time and money! When I say, SP pursued it, it was only that a supervisor would look into it. Interestingly this is where SP suddenly generated the ability for their operatives to phone, email and snail mail me. SP's ability to pursue customers, despite the current Coronavirus situation and being busy with the welfare of elderly parents, for payment on a site that now cannot be operational and therefore hasn't used any amount of electric, is amazingly efficient as are their notifications to escalate to employ a debt collection agency for which, I'd be charged £27.16 for the pleasure. Needless to say, I paid the outstanding bill and then immediately switched supplier. Hopefully, people will read this and avoid ScottishPower. Don't believe the reviews posted on the Trustpilot website, based on my experience and what some of SP's own operatives divulged, situations similar to mine were common and therefore, Trustpilot seems to contain fictitious information. If you have already signed up with SP as you're reading this, I can only wish you good luck in what you will undoubtably find a very frustrating experience.
