At Mentmore Power Services Limited all of our engineers come from a switchgear manufacturing background, working through the various company tiers from apprenticeships, mechanical fitters, wiremen, commissioning engineers and, in some cases, high level management. This gives us a breadth of engineering knowledge on all areas of switchgear and bespoke panel building.

We have the ability to retrofit obsolete devices in existing switchboards through to managing projects, all carried out to a very high standard.

Our close working relationship with the UK's foremost switchboard manufacturers, allows us to offer up-to-date solutions, designed and optimised to meet ever increasing client requirements, including performance, engineering and project deadlines.

LV Switchboards

We carry out a full range of switchboard services from the installation of a PDU through to a complete LV Switchboard and Package Substation, including a full project management service.

We are currently involved in projects that correlate with the following type of switchgear and panels:

  • Power Distribution Units (PDU'S)
  • LV Switchboards
  • Package Substations
  • Change Over Panels
  • Loadbank Panels

LV Switchboard Retrofits

We carry out retrofits to existing switchboards and the replacing of obsolete devices with the latest up-to-date equivalent.

We can design and build bespoke panels to fit within a certain area or to meet access limitations.

This type of work is normally completed at an agreed time to minimise the impact to the client. With the combined knowledge and experience our engineers have, we meet deadlines and carry out the retrofits to a very high standard.


We carry out annual preventative maintenance to switchboards and transformers to the client’s requirements and at a time best suited to minimise disruption.

Power shut-downs for maintenance are often rare on a critical site. When the annual maintenance is carried out to the switchgear we can integrate it with the fixed cable testing, if required. 

We have the knowledge and infrastructure to carry this work out efficiently and competently issuing full reports on completion.
