Friendly and professional service from Alan the electrical engineer. Replaced under cabinet lights in kitchen and replaced outdated PIR outside light. Clean, tidy workmanship and respectful of my property. Also spotted an issue with current fuse box which is now outdated and sent a comprehensive quote for replacement at later date. I was very happy with the care and quality of work today. Plus I was impressed with the customer service from Jordan with great communications from start to finish. Thank you!

I was quoted over £200 for a small job that ultimately cost me £80 using another electrician, but that's not what my 1 star review is for - if MJP Electrical Services want to extort customers that's up to them and I'm sure their customer base will respond accordingly. The 1 star is because I've subsequently received a reminder by both email and SMS every single day for last week badgering me to accept their quote!!

Great service from MJP in the Withywood area. They provided all the information via email and worked with me to determine the best options for what I needed. I had a new fuse board installed, 2 new sockets and all other sockets brought up to safety standard for a reasonable price. They also performed an EICR inspection and booked me in within a few days. Our electrician Daniel was very friendly and completed everything in one day and cleaned up afterward. Fantastic job all round. I would use their service again and recommend them. Edit: I returned to MJP after one of my light bulbs ripped off leaving exposed wires. They came out on the same day as an emergency to fix it. Once again, great work I would recommend
