Why Choose Rudi Electrics for Shed & Outbuilding Electrics Enfield?
Your concerns answered — here’s why Enfield 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 Enfield EN1, EN2, EN3
Enfield is one of our most active areas — we cover all postcodes from EN1 through EN3 — garden offices, sheds, and outbuilding electrics are increasingly common across Enfield 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 Enfield 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 Enfield as part of our wider shed & outbuilding electrics service across North London. For general electrical work in Enfield, see our electrician Enfield page.

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 Enfield EN1, EN2, EN3.
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.

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 Enfield — Across All Property Types
From large Edwardian properties with substantial outbuildings to Enfield Highway semis with garages — we install shed and outbuilding electrics across Enfield EN1, EN2, and EN3.
Victorian & Edwardian Properties
📍 Enfield Town, Chase Side, The Ridgeway, Baker Street, Windmill Hill
Enfield Town's larger Victorian and Edwardian properties often have substantial outbuildings — detached garages, stable blocks, and garden buildings that were originally serviced by gas lighting or early electrical supplies. These are now completely inadequate and often dangerous.
New dedicated circuit from consumer unit to each outbuilding — sized correctly for the load. SWA armoured cable buried at the correct depth. Sub-board in each building with individual MCB protection. Large Enfield properties may have multiple outbuildings requiring a planned multi-run installation.
1930s–1960s Suburban Semis
📍 Grange Park, Bush Hill Park, Enfield Highway, Ponders End, Forty Hill
Enfield's interwar semis typically have detached garages at the end of the garden — often wired informally with a cable from the house on extension leads or 2.5mm² cable with no RCD protection. Grange Park and Bush Hill Park properties often have large gardens with multiple outbuildings.
Proper RCBO-protected circuit from the consumer unit — spare ways added if needed. Armoured cable buried to garage or outbuilding. Distribution board with sockets, lighting, and RCD protection installed inside. Most Enfield semi garage installations complete in one day.
Purpose-Built Flats with Communal Gardens
📍 Enfield Town centre, Southbury Road, Alma Road, Lancaster Road
Flats with garden storage or communal outbuilding access need careful management of the supply route through communal areas. Leaseholders need managing agent approval and the cable route needs to avoid shared infrastructure. Individual flat supplies to garden structures are uncommon but achievable.
Feasibility check before quoting — we confirm flat supply capacity, agree the cable route with the managing agent, and produce a clear plan before any work starts. We coordinate with freeholders throughout and provide full certification on completion.
Garden Offices & Extended Properties
📍 Throughout Enfield EN1, EN2 — garden rooms, home offices, extended properties
Enfield's larger properties are increasingly having garden offices and studios installed. These need a properly specified electrical installation — not a basic shed circuit. Multiple sockets, data, heating, and good lighting require a sub-board and a correctly sized supply from the main consumer unit.
Full garden office electrical installation — dedicated supply, sub-board with RCD, ring circuit for sockets, LED lighting, CAT6 data, and heating circuit. Everything in one day with full certification. EV charger preparation circuit included at the same time if required.

Shed & Outbuilding Electrics Enfield — Frequently Asked Questions
Honest answers to the questions Enfield 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 Enfield? ▼
Outbuilding electrical installation in Enfield 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.
