    Electric Sockets

    Posted 2 days ago

    fitting new power sockets in two bedrooms and a hallway

    the engineers were great, did a really good job and explained everything clearly. there had been some miscommunication between them and their office team which meant they originally arrived without the right equipment but this was quickly resolved and they completed the full job as originally required.

    Great service beginning to end.

    Great service. From Tina within the Checkatrade chat helping me to organise the job, through to Nick coming on site and fixing my battery fitting in a matter of minutes and taking extra care to make sure the fit was good. He even reused part of the old fitting to make sure everything matched and looked good afterwards. Highly impressed.

    Installing 2 bathroom mirrors with lights

    Prompt, and completed the job. Left some mess and tissue blocking the sink but the pair worked efficiently and completed to a good standard. They were also friendly.

    Bathroom & Kitchen Plumbing

    Highly recommend!

    GEM 24/7 was honestly a life saver when my boiler broke late in the evening. It was such a nightmare and I was really panicking until I called and within a very short time, help was on the way! The engineer who came to help was ever so nice and managed to get everything up and running within no time at all. I was so grateful and wouldn't hesitate to call them again (although fingers crossed I won't need to). Thank you team! Highly recommend!
