Dishonest web site and disinterested staff. Claim to offer free delivery to mainland England, it's a lie, they don't. They also manage to stuff review sites with fantastic reviews, but for doing their job, nothing exceptional. Their prices aren't exceptional, many other on-line stores match price anyway so it's only their service which would make them worth dealing with and their service is disinterest. I wouldn't trust Trust Pilot review percentages, click on the 1 star ratings to see how they really treat customers. I highly recommend not using Marks Electrical.
