Full & Partial Rewires
Complete house rewires for period and new-build properties, planned around your life and finished without a trace of disruption.
Part P Compliant — London & Europe
Bespoke high-specification electrical installation for distinguished homes, offices and industrial facilities — smart automation, EV charging, data cabling, full rewires and lighting design, delivered with the precision of fine craft.
The Studio
COS Electrical works on high-specification residential, office and industrial projects — from period townhouses in Kensington to new-build estates across the Home Counties, and the commercial and industrial facilities that demand the same precision. Our electricians are trained to the same standard as the architects and interior designers we collaborate with, because whether it's a luxury home or a working facility, the wiring deserves the same attention as the finish around it.

Our Process
An in-person survey of your property, discussing how you live and what your home needs — no two briefs are the same.
A detailed electrical design — circuit layouts, fittings and a fixed quotation — agreed before a single cable is run.
Clean, considerate site work from vetted, uniformed electricians — dust sheets down, daily clean-up, no exceptions.
Full inspection and testing to BS 7671, certified through our independent accredited testing partner, with documentation handed over for your records — a step we're building in-house as the studio grows.

Based in London, working across the UK and taking on selected residential, office and industrial projects throughout Europe.
Beyond the UK
Our installations are designed and tested to align with both UK and European electrical standards, which means the same high-specification fit-out travels well beyond London. Whether the project is a townhouse in Kensington or a villa on the continent, the design intent, the components and the finish remain the same.
Installations designed and tested in line with the EN 60364 / IEC series used across the EU, alongside UK BS 7671.
The UK and most of mainland Europe share the same voltage and frequency, so smart home, lighting and EV systems transfer seamlessly between properties.
We specify CE-marked fittings, consumer units and smart devices suitable for installation in EU member states.
Our team travels for selected residential, office and industrial projects across mainland Europe, coordinating with local electricians where national regulation requires it.
