These regulations allow us to ensure a world-class standard of service for every one of our clients, from the first consultation and installation stage to final commissioning and handover.








Everyone's electrical requirements are different, ranging from small works such as an additional lighting point to consumer unit upgrades and large-scale works such as complete rewires.As part of the NICEIC Approved Contractors we ensure that all our work is installed to the highest standard in compliance with the current edition of the IEE wiring regulations BS7671.

Whatever works we carry out are carried out to the highest standard and with professionalism and tidiness in mind. We can work on both vented and unvented water cylinders carrying out repairs and new installations.

We can also power flush all your pipework and radiators before your boiler change to ensure you pipework is all clean and scale free.
Ventilation is a very important part of any kitchen and bathroom, as this ensures any smells or steam etc are extracted correctly. Without correctly operating ventilation, a build of mould can occur causing health and building issues.
