Learn moreFour areas of expertise,
one point of contact
That's what separates an installation that works from one you genuinely enjoy using.
01
Electrical expertise
Ten years on site — from private homes to farm buildings and business premises. Compliance isn't optional, it's the starting point.
02
A sense of design
The position of a switch, the colour temperature of a light, the finish of a distribution board: these are design decisions, not details.
03
Smart home know-how
We set up your scenarios ourselves. A connected home that's hard to operate quickly loses its point.
04
Around 17 people
Big enough to handle a large project, close-knit enough to keep the same point of contact throughout.
How a project unfolds
Four steps, one point of contact, and a quote you can discuss line by line.
STEP 01
First contact
You describe your project by phone or via the form, and we call you back.
STEP 02
Site visit & assessment
We come on site to measure, survey the existing installation and understand how you actually use the space.
STEP 03
Detailed quotation
A line-by-line quotation within five working days, depending on the project.
STEP 04
Delivery & commissioning
Installation, testing, tuning and handover of the compliance documents.
