Large estates across Northwood, Moor Park, Radlett, Totteridge, Stanmore and Mill Hill demand energy infrastructure built at their scale. We engineer 30kWp solar and battery systems, fleet-level EV charging and three-phase supply upgrades with full estate rewires - commercial-grade performance in a premium residential specification.
A gated eight-bedroom mansion in Moor Park, a newly developed mega-home on a Totteridge lane or a sprawling detached estate in Radlett carries an electrical load profile that has nothing in common with standard residential installation. You have a 15-metre heated pool, a six-bay garage running a mix of Range Rovers and Porsches, a gym, a home cinema, underfloor heating across 700 square metres and an annexe occupied year-round. Domestic thinking does not scale to this. What scales is a whole-estate energy strategy - one that models your peak concurrent demand, sizes your solar and storage against real consumption data, engineers a three-phase supply where the data justifies it, and delivers every discipline as a single coordinated programme. That is precisely what electricalworks by GThink Ltd builds for premium properties across Northwood, Stanmore, Mill Hill and the Hertfordshire borders.
The estates we work on in Northwood, Moor Park, Radlett and across the Hertfordshire borders are significant capital assets, and every engineering decision we make is evaluated against one criterion: does it perform at the scale this property demands for the next twenty years? We do not propose domestic-grade solutions for commercial-scale loads. We do not underdimension to reduce upfront cost. We build a load-assessed, financially transparent infrastructure roadmap and execute it with the precision, certification and long-term thinking your investment requires.
Four integrated disciplines, built to operate together as a single high-capacity energy system. For gated estates and premium detached homes in Northwood, Moor Park, Radlett, Totteridge, Stanmore, Mill Hill and Hadley Wood where the brief is not comfort - it is total energy command at scale.

When your estate runs a 15-metre heated pool, underfloor heating across 600 square metres, a gym and four EV chargers simultaneously, a 4kWp domestic array is background noise. We design systems from 10kWp to 30kWp and pair them with battery banks of 20kWh to 60kWh, sized against your actual overnight draw and a full cloudy-weather autonomy window. Generation is modelled against every usable roof plane - azimuth, pitch and shading mapped precisely - and anchored in twelve months of your smart meter data so projected savings are credible before any commitment is made. Cabling infrastructure preserves headroom for additional strings and future inverter upgrades as your loads grow.
A six-bay garage running a Porsche Taycan, two Range Rovers, a Tesla and a daily-use runaround requires a fleet-level charging infrastructure - not a pair of domestic wallboxes. We design multi-outlet installations with dynamic load management across four, six or eight simultaneous vehicles, commercial-grade RCBO protection, sub-boards with genuine spare capacity for future additions, and armoured feeders routed cleanly beneath grounds and driveways to detached garages and coach houses. Charge windows are coordinated with surplus solar generation to reduce grid draw. Every installation is commissioned as a unified programme with annotated single-line drawings left on site, so your contractor can add outlets in five years without starting the design from scratch.
A newly developed Moor Park mega-home or a completely redeveloped Radlett estate running pools, heat pumps, a home cinema, a gym, a six-charger EV bay and a whole-home automation system simultaneously is operating at commercial load levels. We carry out a formal BS 7671 diversity analysis, model worst-case concurrent demand and liaise with UK Power Networks on three-phase upgrades precisely when the data justifies the application - not as a default recommendation. Rewires are executed in sequenced zones so the property remains fully habitable throughout. Distribution boards are specified with tier-separated circuits, coordinated surge protection and inverter export allowances already built in - leaving the infrastructure ready for any smart system or automation overlay without emergency remedials.
Sweeping tree-lined driveways, gated arrival courts, large formal gardens and multi-zone interiors on a Totteridge or Stanmore estate are not lit with a handful of spotlights - they are orchestrated as a single, programmed landscape. We design and install full-estate lighting automation alongside the primary electrical programme: Lutron or KNX scene control for interior zones, dusk-triggered path and perimeter lighting, architectural façade washes, pool surround illumination and occupancy-based garden circuits all managed from a single interface. Smart home integration ties lighting to security, access control, HVAC and AV so the entire estate responds as a coherent system. Cabling containment and data routing are resolved at rewire stage - not retrofitted through finished walls two years later.
Gated estates and large-footprint detached properties in Moor Park, Totteridge, Stanmore, Mill Hill and Hadley Wood represent some of the most technically complex residential energy projects available. These are the capabilities that allow us to deliver them at the scale and standard they demand.
We do not issue quotes from a price list. Before any product is named, we pull twelve months of smart meter data, map every high-load circuit across the estate - pool, gym, heat pump, EV fleet, underfloor - model solar generation potential across all usable roof planes and calculate battery sizing against overnight consumption and a defined grid-outage resilience window. The output is a financially transparent model your developer, independent adviser or quantity surveyor can scrutinise. Engineering-led decisions, not sales-led ones.
Estates in Northwood, Radlett and Totteridge routinely include detached six-bay garages, pool plant rooms, garden rooms, annexes and gated gatehouse structures that each require their own distribution feeds. We design and coordinate armoured sub-main routing through grounds with minimal surface disruption, connect every outbuilding to the main distribution system and commission all circuits as a unified installation. One project manager. One programme. One complete set of certification documents at handover.

The estates we engineer in Stanmore, Mill Hill and across the Hertfordshire borders are long-term assets built to evolve. We specify three-phase distribution boards with deliberate tier separation and genuine spare circuit capacity, battery systems with future expansion slots, EV sub-boards with headroom for double the current outlet count, and solar inverter architectures with string capacity for additional panels. Every decision is made with a twenty-year horizon so the infrastructure we commission today absorbs the technology your household adopts next - without reinstallation, without emergency remedials.

How large an array can your roof planes realistically support? What battery capacity covers your overnight draw plus a full resilience margin for your critical loads? Does your current single-phase intake have the headroom for a six-charger EV bay, a pool heater and a 900-square-metre underfloor heating zone running simultaneously - or does the supply need upgrading first? We answer these questions with engineering-grade data: your twelve-month smart meter consumption profile, your roof’s modelled irradiance, your peak concurrent demand curves. Accurate answers before any commitment. That is the standard of consultancy we bring to every estate in Northwood, Moor Park, Radlett, Totteridge, Stanmore, Mill Hill and Hadley Wood.

Every specification begins with your property’s actual consumption data and load profile - not a manufacturer’s default output table. Systems are sized to your estate’s real demand, maximising financial return and avoiding the undersizing that leaves large-property owners drawing from the grid all night.
The engineer who models your estate’s energy system designs the installation and is present at every critical stage of delivery. No translation loss between a sales consultant and a subcontracted crew. One technical thread from the first site survey to the sealed commissioning report.
NICEIC-registered for all electrical works, MCS-certified for solar installations, OZEV-compliant for EV charging infrastructure. Every credential is publicly verifiable by your insurer, surveyor, developer’s QS and any future buyer - without our involvement.
Every system includes deliberate expansion headroom: spare battery expansion slots, EV sub-board capacity for double the current outlet count, solar inverter string headroom for additional roof panels. The infrastructure commissioned today absorbs your estate’s next decade of upgrades without replanning, replastering or starting from scratch.
Delivering genuine high-capacity energy independence across gated estates and large-footprint properties in Northwood, Moor Park, Radlett, Totteridge and Stanmore demands a fundamentally different order of technical competence than standard residential installation. These are the foundations we bring to every project at this scale.
A full estate rewire on a Radlett or Moor Park mega-home is a once-in-a-generation opportunity to build the backbone for every system the property will carry for its lifetime. We install structured cabling pathways - correctly containment-rated, cleanly routed through agreed concealed routes - that support Lutron or KNX lighting control, multi-zone AV distribution, IP-based access and security, HVAC zone management and full smart home automation from a single riser. Every route is documented in a wiring schedule your subsequent integrators and M&E contractors can act from directly.

A large Moor Park or Totteridge estate running pool heating, EV fleet charging, heat pumps and whole-home automation simultaneously is frequently operating at the ceiling of a single-phase 100A intake. We conduct a formal load analysis under BS 7671 diversity factors, determine whether a three-phase upgrade is technically necessary or whether intelligent load management resolves the issue at lower cost, and - where a DNO upgrade is genuinely required - manage the full UK Power Networks application from technical submission through to energisation.
At the scale of a 25kWp solar system, a 40kWh battery bank or a six-outlet commercial-grade EV installation on a Northwood or Hadley Wood estate, component quality determines whether the system is a twenty-year asset or a five-year liability. We specify Schneider Electric distribution gear, SolarEdge or SMA inverters, Tesla or Sigenergy premium battery storage, and Eaton or ABB protective devices - all sourced through authenticated supply chains. Certificates of conformity and product provenance documents are included in your handover pack as standard.
Georgi Tangarov founded GThink Ltd on a precise observation: the large-footprint gated estates and newly developed mega-homes of outer Northwest London and the Hertfordshire borders were being served by contractors whose technical depth, component specifications and delivery standards were designed for ordinary suburban houses - not for properties running at the energy intensity of a small commercial building. The answer was a practice structured entirely around this project type: commercial-grade technical rigour, premium component specification and personal engineering accountability from the first survey to the final handover. Every project in Northwood, Moor Park, Radlett and across the Herts corridor is led by a senior engineer. Not a sales team.
Picture your Moor Park or Totteridge estate on a clear July afternoon: the 15-metre pool running on solar, the six-bay garage completing its overnight EV charge window on surplus stored energy, underfloor heating across 700 square metres pre-conditioned from the battery bank, the driveway and garden lighting sequencing automatically at dusk, and the entire smart home operating precisely as designed - without a single manual input. The grid is connected but largely irrelevant. Your energy running costs are a fraction of a comparable property without this infrastructure. Your asset value has measurably improved. And the system that delivers all of this was commissioned once, certified completely, and requires nothing beyond an annual service visit. This is what estate-scale energy engineering produces when it is done properly and at the right specification level.
The views of homeowners and their project managers across Northwood, Moor Park, Radlett, Totteridge, Stanmore, Mill Hill and Hadley Wood - after system commissioning, months of real performance data and, in most cases, a second project with us.
A heated 15-metre pool with a heat pump and filtration system can consume 8,000 to 14,000kWh per year - more than an entire standard household’s electricity use. On estates in Moor Park or Totteridge, this single load alone typically justifies a 12 - 18kWp array, and sizing solar generation against it produces the shortest payback period of any renewable investment at this property type.
Not every large NW property needs three-phase supply - but many of the largest ones do. The question is never answered by assumption. A formal BS 7671 diversity analysis quantifies your true worst-case concurrent demand. For estates in Northwood and Radlett running six EV chargers, pool heating, heat pumps and AV simultaneously, three-phase is often the only viable engineering answer. For those where it is not, intelligent load management achieves the same outcome at far lower cost and timeline.

The most common battery sizing error at estate scale is specifying against peak inverter output rather than actual overnight consumption. On a Totteridge or Mill Hill property running sustained overnight loads - climate control, security, refrigeration, standby heating - this produces severe underspecification. We size storage against your actual overnight demand profile and add a defined resilience margin, producing a system that genuinely replaces grid dependency rather than supplementing it marginally.
We pull twelve months of smart meter consumption data, survey every high-load circuit across the main house and all outbuildings, map solar generation potential across all usable roof planes and model concurrent peak demand before a single specification item is discussed.
Solar array sizing, battery architecture, fleet EV infrastructure, three-phase supply assessment, full estate rewire and smart lighting strategy are designed as a single coherent programme - with a transparent financial model and a phased delivery schedule your developer or QS can review.
Works are sequenced across the main house, garages, outbuildings and grounds to maintain full habitation throughout. A dedicated programme manager coordinates all trades within a single timeline so your household experiences one managed intervention - not repeated visits over months.
Every system is formally commissioned, performance-benchmarked and certified: NICEIC for all electrical works, MCS for solar, OZEV for EV infrastructure. All documentation is packaged for your insurer, building control, surveyor and any future buyer or occupier.
We provide monitoring configuration, annual service scheduling and a retained as-built record. When the estate adds further vehicles, expands the property or increases generation capacity, the infrastructure we built accommodates it without a fresh design process.
