New electric cooker has to be installed, but before then the safety switch set on the wall (tiles section) should be moved to one side around 30 cm away from the cooker (see reconstructed photo). In addition fit blank plate on the existing box. The cooker will be delivered on Saturday 10 November afternoon. The house is in Canada Water (15 mins. from Westminster on Jubilee Line). No parking costs. I need a fully qualified electrician to ensure there is no problem with the work or the cooker’s warrantee. In addition I will need for the work a certified bill. Could you please give me a quotation broken down by tasks? The cooker’s supplier will pay to move the switch and I will pay for the installation. Many thanks, G Vera
