Commercial Electrical Installations from a Certified Electrician
We work with offices, retail units, restaurants, schools, and landlords across North West London.
Commercial electrical work needs careful planning around trading hours and building management. Most projects are completed out of hours or in phases so your business keeps running.
From a single shop refit to a multi-floor office rewire, we manage the job from first fix through to final certification. We liaise directly with building managers, landlords, and local authority building control on your behalf.

Industrial Electrical Work from a Certified Electrician
Warehouses, workshops, and factories have different demands to houses or offices. Higher loads, three-phase machinery, containment systems, and strict compliance requirements mean you need electricians who understand industrial environments.
We have wired production lines, installed motor control panels, and carried out planned shutdowns for preventative maintenance across sites in North West London and beyond. If your facility needs power, we design, install, and certify it.

Since June 2020, landlords in England are legally required to have an Electrical Installation Condition Report (EICR) on their rental properties at least every five years. If your property does not have a valid EICR, you could face fines of up to £30,000 per property.
We inspect hundreds of rental properties every year for private landlords, letting agents, and property management companies across North West London. If remedial work is needed to pass the inspection, we can usually complete it the same week - so you are not left waiting for a separate contractor.

Frequently Asked Questions About Our Certified Electrician Services
How much does a full house rewire cost?
Cost depends on property size, number of circuits, and existing wiring condition. A typical 3-bed semi in North West London is often between £3,500 and £5,500, and we provide a fixed written quote before work starts.
Do I need to be home while you work?
Not necessarily, as many clients provide a key or arrange access through a neighbour, agent, or building manager. We confirm access arrangements with you before the job starts.
How long does an EICR take?
A standard flat or small house usually takes around 2-3 hours, while larger properties and HMOs take longer. We give you an estimated duration when you book.
Are you Part P registered?
Yes, we are registered to self-certify domestic electrical work under Building Regulations Part P. You receive full certification without needing separate local authority inspection.
Can you work outside normal hours?
Yes, especially for commercial clients who need work outside trading hours, and we regularly carry out evening and weekend installations. Emergency call-outs are available 24/7.
What areas do you cover?
We are based in Stanmore and cover Harrow, Wembley, Edgware, Pinner, Ruislip, Hendon, Finchley, and the wider North West London area. For larger commercial or industrial projects, we work further afield across South East England.

EV Charging & Security Lighting by a Certified Electrician
Electric vehicle ownership is growing fast, and so is demand for home and workplace charger installations. We install dedicated EV charging circuits with their own protection, properly rated cabling, and - where applicable - help with OZEV grant paperwork to reduce your costs.
For security, we design and install PIR-triggered floodlighting, dusk-to-dawn perimeter lighting, and CCTV power supplies for both residential and commercial properties. Good lighting is still the single most effective deterrent against break-ins.
