"Mariusz has performed a number of projects for me and he's my go-to person for any electrical work. Most recently he installed four light fittings and a new dimmer switch in our house. All done very professionally, quickly and tidily. All the fittings were still boxed and it was no trouble for him to assemble them all and install them. If you're looking for a professional and reliable electrician, choose Mariusz!"
