Leaving a recommendation for HomeCert. Extremely knowledgeable, friendly and professional electricians who have now done substantial and fiddly work throughout our home, including installing new downlights, sockets, moving light switches, replacing the PCU, a full test and certification, fault-finding and tidying of work carried out by previous electricians! They have worked very neatly with the minimum of disruption and have been adaptable when I changed my mind about fittings at various points. A very happy customer of HomeCert.
