Why Choose Rudi Electrics for Shed & Outbuilding Electrics Wood Green?
Your concerns answered — here’s why Wood Green homeowners trust us to wire their sheds, garden offices, and outbuildings.
“Can I just run an extension lead from the house to my shed? Surely that’s fine?”
It’s one of the most common causes of shed fires and garden fatalities. Extension leads aren’t designed for permanent outdoor use — they degrade, flood with moisture, and aren’t protected against faults. A proper SWA armoured cable installation costs far less than the risk. We’ll get it done safely and certified.
“I want sockets and lights out there — but I’m worried about it tripping my whole house.”
We install a dedicated circuit from your main consumer unit installation with its own RCBO protection, so a fault in the shed cannot affect your house circuits. The outbuilding gets its own small consumer unit too — completely independent, properly earthed, and designed to handle whatever you plug in out there.
“The cable has to cross the garden — I don’t want it dug up or looking a mess.”
We either bury the SWA cable at the correct depth with warning tape above it, or clip it neatly along fences and walls using galvanised clips. Both methods are permanent, weatherproof, and tidy. We’ll discuss both options during the free site visit and work around your garden however you need.
“Do I need to notify anyone? I don’t want problems when I sell the house.”
Yes — any new circuit requires Part P notification. As NICEIC registered electricians, we self-certify the work and notify Building Control on your behalf. You receive an Electrical Installation Certificate on completion, which your solicitor will ask for when you sell. We handle the paperwork, you keep the peace of mind.
Shed & Outbuilding Electrics in Wood Green N22
Wood Green has a dense mix of Victorian terraces and 1930s semis — garden offices, sheds, and outbuilding electrics are increasingly common across Wood Green as homeowners convert outbuildings for home working. We carry armoured cable and all fittings on every van. We can also combine with a CCTV installation visit on the same day.
Most Wood Green outbuilding jobs involve a new dedicated circuit from the main consumer unit, SWA armoured cable run to the outbuilding, and a small consumer unit or fused spur inside. Typical installation takes a full day. We cover Wood Green as part of our wider shed & outbuilding electrics service across North London.

Shed & Outbuilding Electrics — Our Work
Real garden offices, sheds and outbuildings wired across North London — fully certified.
What Can We Install in Your Shed or Outbuilding?
From a basic light and socket to a fully wired garden office with heating and data points — here's what's possible with a professional outbuilding electrical installation across Wood Green N22.
Power & Sockets
Double sockets positioned where you actually need them — not just one on the back wall. We size the circuit for your intended use, whether that's a lawnmower and a workbench or a full garden office setup with monitors, standing desk, and a printer. Correct cable sizing for distance and load every time.
Lighting
LED batten lights for workshops and utility sheds, downlights for garden offices, and switched circuits so you can control zones independently. We fit the light fittings, run the wiring, and install the switches — leaving you with a properly lit space that's practical to use day and night.
Small Consumer Unit
Every outbuilding installation gets its own small consumer unit installation with RCD or RCBO protection — completely independent from your house circuits. A fault in the shed cannot trip your home. We install a TT earthing system (earth rod) where required and size the unit for any future circuits you might want to add.
Armoured Cable Supply
We run SWA (steel wire armoured) cable from your main house consumer unit to the outbuilding — either buried underground at the correct depth with warning tape, or clipped neatly along fences and walls. Never twin-and-earth or extension leads, which deteriorate outdoors and create serious safety risks.
Garden Office Fit-Out
Working from your garden office means you need it properly equipped — multiple double sockets, USB charging points, a dedicated circuit for a heater or air conditioning unit, data points for a wired internet connection, and appropriate lighting installation for a working environment. We design and install the full electrical fit-out in one visit.
Security & External Lighting
PIR floodlights covering the approach to the outbuilding, an external socket for power tools or a pressure washer, and a doorbell or intercom if needed. All outdoor fittings are IP65-rated for permanent external use. We can also tie the outbuilding into your existing CCTV installation system or add a new camera covering the area.
Not sure what your shed or outbuilding needs? We carry out a free site visit and advise on the right setup for your intended use — before any work is quoted or agreed.
How We Complete Your
Shed or Outbuilding Installation
From the initial site visit to final certification — every outbuilding installation is planned, installed, and certified to BS 7671 with Part P notification handled on your behalf.
Free Site Visit
We visit to assess the cable route from your main consumer unit to the outbuilding, measure the distance, check what's already in place, and understand how you intend to use the space. We advise on the right setup — basic shed supply or full garden office fit-out — before any commitment is made.
Fixed Quote
You receive a written fixed-price quote covering armoured cable, consumer unit, earthing system, sockets, lighting, and all certification. We calculate the correct cable size for your run distance and load — and we tell you exactly what you're getting before you agree to anything.
Materials & Cable
We source the correct SWA armoured cable sized for your distance and load, the consumer unit, earth rod and clamp, IP-rated sockets and fittings for outdoor use, and all accessories. Everything is specified correctly — no undersized cable, no shortcuts on the earthing system.
Installation
Cable routed from the house consumer unit — buried underground with warning tape or clipped along fences. Earth rod driven, outbuilding consumer unit fitted and wired, sockets and lighting installed inside. New circuit added to your main board with its own RCBO protection. Typically completed in a single day.
Testing & Sign-Off
Full electrical testing to BS 7671 — insulation resistance, earth loop impedance, continuity, and RCD operation tests on the complete installation. Both the house circuit and the outbuilding consumer unit are tested and verified before we sign off. Nothing is left live until it passes.
Certification & Handover
You receive an Electrical Installation Certificate covering the full installation — essential for your insurance and required by your solicitor when you sell. As NICEIC registered electricians we notify Building Control on your behalf. We walk you through everything before we leave.

Shed & Outbuilding Electrics Wood Green — Across All Property Types
From Victorian terraces on Lordship Lane to HMO properties throughout N22 — we install shed and outbuilding electrics across Wood Green N22.
Victorian & Edwardian Terraces
📍 Lordship Lane, Wolves Lane, Marlborough Road, Truro Road
Wood Green's dense terrace streets have rear gardens accessed through the house or side entry — cable routing to sheds and outbuildings requires careful planning. Long cable runs across narrow gardens, plus the need for buried armoured cable to avoid the lawnmower hazard.
Buried SWA armoured cable at 500mm depth from consumer unit to outbuilding. Dedicated RCBO-protected circuit — no more extension leads across the garden. Sub-board in shed with sockets and lighting. Most Wood Green terrace shed installations complete in half a day.
1930s–1950s Semis & Council Properties
📍 Noel Park Estate, White Hart Lane, Penshurst Road, Coburg Road
Wood Green semis and council properties often have outbuildings or lockup garages with no proper electrical supply — or informal wiring that hasn't been assessed for decades. Solid concrete paths and drives make armoured cable burial more complex but still achievable.
Armoured cable to outbuilding — we plan the route to minimise disruption to concrete paths where possible, or use a lance to pull cable under paths without cutting. Distribution board, sockets, and lighting installed inside. Part P certified.
Flats & HMO Properties
📍 Wood Green Central, Heartlands development, Turnpike Lane, The Mall N22
HMO properties and flats in Wood Green sometimes have communal storage buildings that landlords want to improve. Supplying communal outbuildings requires agreement with all relevant parties and careful documentation of the supply and protection arrangements.
Communal outbuilding supply — we assess the supply source, agree the route and protection arrangements, and install correctly. All documentation provided including certification suitable for Haringey Council HMO licensing purposes.
Garden Offices & Extended Properties
📍 Throughout Wood Green N22 — garden offices, workshops, home studios
Garden offices have become increasingly popular across Wood Green N22. For full-time working you need more than a basic shed supply — multiple sockets, data connection, heating, and good lighting all require a properly planned installation.
Full garden office electrical installation — dedicated circuit, sub-board, ring circuit for power, LED lighting, armoured CAT6 for data, and heating circuit. Completed in one day. We also add EV charger preparation at the same time if required.

Shed & Outbuilding Electrics Wood Green — Frequently Asked Questions
Honest answers to the questions Wood Green homeowners ask us most before booking a shed or outbuilding electrical installation.
For official electrical safety guidance, visit Electrical Safety First.
How much does shed or outbuilding electrical installation cost in Wood Green? ▼
Outbuilding electrical installation in Wood Green typically costs £400–£900 for a standard shed or garage — covering armoured cable from the consumer unit, a sub-board with RCD protection, sockets, and lighting. Garden offices with multiple circuits and data points are typically £600–£1,200. We provide a written fixed price after a free survey. Call 07932 772 050 or use the contact form.
Do I need permission or certification for shed electrics? ▼
Yes. Any new circuit — including a supply to a shed or outbuilding — is notifiable work under Part P of the Building Regulations. As NICEIC registered electricians we self-certify the work and notify Building Control on your behalf. You receive an Electrical Installation Certificate on completion. This is essential for your home insurance and will be requested by your solicitor when you sell the property.
What cable do you use to run power to a shed? ▼
We use SWA (steel wire armoured) cable — the correct cable for all permanent outdoor and underground installations. It's mechanically protected, weatherproof, and designed for long-term use in all conditions. We never use standard twin-and-earth or flex cable outdoors — these are not rated for underground use or permanent external exposure and deteriorate rapidly. The cable size is calculated based on your run distance, load, and voltage drop requirements.
Will it trip my house if something goes wrong in the shed? ▼
No — not if it's installed correctly. We connect the outbuilding on a dedicated circuit with its own RCBO at your main consumer unit. A fault in the shed will trip only that circuit, leaving the rest of your house unaffected. The outbuilding also gets its own small consumer unit with independent RCD protection, so faults inside the shed are dealt with locally before they can even get back to the house board.
Does the cable have to be buried underground? ▼
Not necessarily. We offer two routes — underground (buried at the correct depth of at least 500mm under paths and 600mm under unprotected areas, with warning tape above) or surface-clipped along fences, walls, and soffits using galvanised clips. Both methods are safe and permanent. We discuss both options during the free site visit and work around your garden layout, existing paths, and planting. The best route depends on your specific garden.
What earthing system does an outbuilding need? ▼
Outbuildings require a TT earthing system — a separate earth rod driven into the ground at the outbuilding, independent from your house earthing arrangement. This is because the SWA cable's armour is not suitable as the sole protective conductor for a remote building. The earth rod provides a reliable fault path to earth for the outbuilding's consumer unit. We install the earth rod and clamp as standard on every outbuilding installation and test the earth loop impedance to confirm it meets BS 7671 requirements.
How many sockets and what size supply do I need? ▼
It depends entirely on how you intend to use the space. A basic garden shed for tools and a lawnmower needs a simple supply — a couple of sockets and a light on a 2.5mm² circuit is usually sufficient. A garden office running computers, monitors, a standing desk, and a heater needs a larger supply — potentially a 6mm² cable and multiple circuits on its own consumer unit. We calculate this during the free site visit based on everything you plan to run simultaneously.
Can you wire a garden office for broadband and data too? ▼
Yes. We can run a Cat6 data cable alongside the electrical supply from your house to the outbuilding — giving you a wired broadband connection that's far more reliable than home network & WiFi across a garden. The data cable can be run in the same trench as the SWA or clipped alongside it on the surface route. We terminate it with a proper data socket inside the garden office. Much better than a WiFi extender for video calls and remote working.
How much does shed or outbuilding electrics cost in North London? ▼
Our starting package — armoured cable supply, small consumer unit, a couple of sockets and a light — starts from £750. This covers a typical garden shed or small outbuilding with a straightforward cable run. Garden office fit-outs with multiple circuits, data points, and additional sockets typically range from £900–£1,400 depending on scope. All prices are fixed and confirmed after a free site visit — no extras on the day.
My shed already has power from years ago — can you check if it's safe? ▼
Yes, and we strongly recommend it. Older outbuilding supplies are frequently found on undersized cable, without RCD protection, with no earth rod, or on cable that has deteriorated over time. We carry out a full inspection of the existing installation — checking the cable type and size, the earthing arrangement, the protection devices, and the condition of any existing fittings. We then tell you honestly what's safe to keep, what needs upgrading, and the cost before any work is agreed.
How long does a shed electrical installation take? ▼
Most shed and outbuilding electrical installations are completed in a single day. A basic supply with a couple of sockets and a light typically takes 4–6 hours. A full garden office fit-out with multiple circuits, data cabling, and a sub-consumer unit may take a full day or occasionally two. We agree the scope and timescale in advance — you'll always know what to expect before we arrive.
