Fit-outs
Spaces ready to move into
Whether it's a new office, a refit or a unit between tenants, the electrical installation is planned around how the space will be used and the date it needs to be ready. We work direct for building owners and occupiers, and as a subcontractor for main contractors. Every installation is tested and certified on completion.

From shell to working office
Full fit-outs and refits
From a bare shell to a working office, we can take care of the whole electrical side:
- Small power: sockets, floor boxes and dado or perimeter trunking positioned to suit the furniture layout
- Lighting, including LED panels, controls and emergency lighting
- New or upgraded distribution boards and sub-mains to feed the space
- Containment for power and data: trunking, cable tray, basket and conduit, in steel or PVC
- Data cabling and comms cabinets, installed and terminated
- Supplies for kitchens, comms cabinets, heating and air-con units
- Smart switching and controls, such as contactors, timers, remote control and linked sensors
- Fire alarm installation, with the design and commissioning carried out by our specialist fire alarm partner
Installations are planned around how the space will be used.

Layouts and tenants
Layout changes and tenant changeovers
Teams grow, desks move and rooms are split or opened up. Landlords need units turned round between tenants with as little void time as possible.
We strip out redundant installations, make the existing installation safe and install what the new layout needs, with certification on completion.


Containment
Containment
Cabling that's protected and easy to add to later. We install trunking, cable tray, cable basket and conduit, in steel, galvanised steel or PVC to suit the space. For full office installs that includes dado and perimeter trunking for power and data.
Routes are set out straight, supported correctly and sized with spare capacity for future changes. We can install it ready for your data or other installers to cable, or do the cabling ourselves.

Period buildings
Older, period and listed buildings
Modern electrics that work with an older building, not against it. In period and listed buildings, cable routes, board positions and containment are planned around the building's character.
On a recent city-centre refurbishment in Leicester we installed the new distribution boards and steel cable tray in the building's vaulted cellar. You can read more about that job below.
Data
Data cabling and comms cabinets
A network that's ready when your team moves in. We install data cabling as part of the fit-out, including full comms cabinet installs with every cable terminated at both ends. We can supply network switches and install Ubiquiti UniFi wireless access points.
For simple setups we can get you up and running. For larger offices that need more network setup and management, we install and terminate everything, then hand over to your IT team or provider for the network configuration.
Controls
Smart switching and controls
Some spaces need more than a light switch. Where heavy loads need to come on together, we wire them through contactors, so one button, a timer or a remote app switches the lot safely. We can add a last-man-out switch so everything goes off when the last person leaves.
We can also link sensors to equipment, for example a CO2 detector that starts an extract fan when levels rise. See the Hot Pod Yoga case study below for an example.
Supplies
External and equipment supplies
Power where your equipment needs it, inside or outside the building. We install dedicated supplies, for example external power for InPost parcel lockers, signage and other kit. Each one is run safely, protected properly and certified.

Case study
Hot Pod Yoga, Leicester
An empty industrial unit in Leicester turned into the new Hot Pod Yoga studio. We carried out the full electrical installation and managed the fit-out, including a new distribution board, showers and changing rooms, and CCTV.
The pod sockets switch on together from one button or an app, through contactors, with a last-man-out switch to turn everything off. CO2 detectors are linked to an acoustic extract fan and ducting, which we supplied and installed.

Case study
Period building refurbishment, Leicester city centre
A period building in Leicester city centre given modern electrics while keeping its character. New distribution boards, sub-mains, a main isolator and metering were installed in the vaulted brick cellar, which became the plant room.

Case study
Strong Pilates, Leicester
A studio with lighting that can be dimmed from several points around the room. Our full electrical fit-out for Strong Pilates in Leicester included a new distribution board, fire alarm wiring and dimmable LED lighting on Zano controls.


Case study
Industrial unit to offices, showroom and warehousing, Kibworth
One open warehouse unit in Kibworth made into a working warehouse, offices and showroom for a point-of-sale display supplier.
Warehouse: round LED high bays, emergency lighting, and three phase and outdoor sockets. Offices and showroom: a new sub-main, the full electrical fit-out, data cabling and cabinet, CCTV wiring, and electrical supplies and rotary isolators for the air conditioning.
