Electrical Wiring Installation London
Whether you’re adding a new circuit for a home extension, wiring a converted loft, or fitting out a new commercial space, new electrical wiring installation is where a mistake is most costly to fix later, since it’s usually buried in walls, floors or ceilings before anyone finds out something was done wrong. First Strike Electrical Ltd has installed electrical wiring across London homes and businesses since 1999, and as an NICEIC approved contractor, every installation is designed and tested to current wiring regulations, BS 7671.

What’s Involved
New wiring installation starts with understanding what the circuit needs to carry, and working back from there to the right cable size, the right protective device, and the right route through the property. We plan cable runs to avoid obvious damage risks, size circuits correctly for their intended load rather than just matching whatever was there before, and test every new circuit before it’s connected to supply. Because any new circuit is notifiable work under Part P of the Building Regulations, we handle the correct certification and registration as standard, not as an optional extra.
Typical Wiring Installation Projects
- New circuits for extensions and loft conversions
- Additional sockets and circuits for home offices or workshops
- Wiring for kitchen and utility appliances that need a dedicated supply
- New circuits to outbuildings, garages and garden rooms
- Full first-fix wiring for commercial fit-outs and refurbishments
We also install structured cabling for data and network points alongside power circuits where a project needs both.
Working Around Other Trades
New wiring installation rarely happens in isolation. On renovations and fit-outs, we coordinate with builders, plasterers and other trades so first-fix wiring happens at the right point in the programme, and final connections and testing happen once walls are closed up and finishes are going in, not before. Getting this sequencing right avoids costly delays and the need to open up finished walls because a connection was missed.
Planning New Circuits Properly
A common mistake on renovation projects is deciding on socket and light positions too late, after plastering, when moving or adding a circuit means cutting back into finished walls. We’d always recommend involving an electrician at the design stage of a renovation or fit-out, even before builders start, so circuit routes and positions are agreed before anything is closed up, rather than retrofitted awkwardly afterwards.
Why Choose First Strike Electrical
NICEIC approved, meaning our design and installation work is independently assessed against national standards, and trading in London since 1999, we’ve installed wiring in property types ranging from Victorian conversions needing entirely new circuits behind original features, to modern new-build shells with nothing in place at all. We’ll give you a clear quote based on what the job actually needs, not a generic day rate that doesn’t reflect the specifics of your project.
Frequently Asked Questions
Is new wiring installation always notifiable work?
Yes, any new circuit is notifiable under Part P of the Building Regulations, and we handle the certification this requires as standard.
Can you install wiring as part of an extension or loft conversion?
Yes, we regularly work alongside builders on extensions and conversions, timing first-fix wiring and final connections to fit the wider building programme.
Do you install data and network cabling alongside power circuits?
Yes, we can install structured cabling for phone and data points at the same time as power wiring, useful for fit-outs and office moves where both are needed.
How do you decide what size cable and circuit protection a new installation needs?
Based on the specific load the circuit needs to carry and the route it takes through the property, assessed against the requirements of BS 7671, rather than simply matching an existing circuit elsewhere in the building.
When in a renovation project should I involve an electrician?
As early as possible, ideally before builders start, so socket and circuit positions are agreed and cable routes planned before walls are closed up.
