Large properties generate large energy bills - and exceptional opportunities. We engineer whole-estate solar and battery systems, multi-vehicle EV infrastructure and intelligent electrical upgrades that transform high-consumption homes in Kingston, Teddington, Cobham and across the Surrey borders into self-sufficient, low-running-cost assets built for decades of premium performance.
A five-bedroom detached home in Kingston upon Thames, a riverside estate in Teddington or a country property on the Cobham-Surrey borders carries an electrical infrastructure requirement that simply does not compare to a city terrace. You have a heated pool, a double garage, an annexe, underfloor heating across multiple zones, a wine room and a household that runs four or five vehicles simultaneously. Standard residential electrical thinking does not apply. What applies is a whole-property energy strategy - one that quantifies your peak demand, models your generation potential, right-sizes your storage and future-proofs your supply for the technology your household will adopt over the next fifteen years. That is precisely the service electricalworks by GThink Ltd delivers for premium properties across Southwest London and the Surrey borders.
The homes we work on in Kingston, Teddington and across Surrey are significant assets. Every engineering decision we make is evaluated against two criteria: does it maximise the property's energy performance today, and does it preserve optionality for the upgrades your household will want in ten years? We do not over-specify for margin or under-specify for price. We build a financially and technically coherent roadmap - load-assessed, phased where appropriate, certified to the highest standard - and then we execute it with the precision your investment demands.
Four integrated disciplines, designed to work together as a single energy system. For homes in Kingston, Teddington, Richmond, Cobham and the Surrey borders where the goal is not merely convenience - it is genuine energy independence.

When your home runs a heated pool, underfloor heating across four hundred square metres and multiple EV chargers, a domestic-scale solar system will not move the dial. We design arrays from 10kWp to 30kWp and pair them with battery banks sized for overnight consumption and a full cloudy-weather buffer day. Generation is matched to roof azimuth, pitch and shade - not rule of thumb. Every design is anchored in your smart meter profile so projected savings and export income are credible before you commit, and cabling headroom preserves paths for panels or inverter upgrades as your loads evolve across the next decade.
A four-car garage merits four chargers that stagger load thoughtfully - not a solitary socket chased through with extension cabling. We deliver multi-outlet infrastructure with disciplined shared management across simultaneous vehicles, aligning charge windows with surplus solar when it stacks financially, and we specify commercial-grade protection sized for annexes or coach-house distribution branches. Estates across Cobham, Kingston or Teddington receive armoured feeders routed cleanly through grounds, commissioning packaged as one disciplined programme with annotated drawings left on site so supplementary wall-mounted units draw from retained spare ways instead of forcing a wholesale enclosure retrofit midway through ownership.
Large estates running heated pools, aggregated heat pumps, clustered EV fleets and cinematic AV concurrently will strain a lone single-phase intake long before façade finishes dull. Engineers here script diversity-balanced studies, shepherd DNO applications only when uplift is genuinely warranted and nominate three-phase boards with purposeful spare capacity, disciplined surge tiers and inverter export allowances already harmonised laterally. Works roll through the house in phased zones so life continues upstairs while cabling containment zoning, supplementary bonding and segregation choices leave corridors ready for smart lighting backbones and automation overlays precisely when furniture returns after commissioning - not through emergency remedials.
From sculpted façade washes and arrivals courts to ballroom ceilings and kilometre-long drive borders, illumination is authored as infrastructural cabling and control strategy alongside your primary energy programme rather than pasted in after finishes close. Astronomical dusk logic, biometric entry ties and layered occupancy merge exterior path washers with softened interior palettes in synchronised moods. Commissioning validates colour rendering, glare limits and failover behaviour so gardens, elevations and salons read as a single choreography whether you host summer evenings overlooking the Thames or midwinter arrivals along sweeping Surrey laurel lines.
The estates and large detached homes across Kingston upon Thames, Teddington, Cobham and the Surrey borders represent some of the most complex residential energy engineering projects in the UK. These are the capabilities that allow us to deliver them at the standard they demand.
We do not quote from a price list. Before a single product is specified, we pull twelve months of smart meter data, map your high-load circuits (pool, heat pump, EV, underfloor), model generation potential across every usable roof plane and calculate battery sizing against both overnight demand and grid outage resilience. The output is a financial model with a realistic payback range and a technical specification your independent adviser can scrutinise. Engineering-led decisions. Not sales-led ones.
Large properties in Teddington, Cobham and Kingston frequently include detached garages, pool plant rooms, garden offices and annexes that need integrating into a single electrical and energy strategy. We coordinate armoured sub-main routing through grounds with minimal surface disruption, connect outbuildings to the main distribution system and commission all circuits as a unified installation. One project. One programme. One set of certification documents.

The homes we engineer for in Kingston and Surrey are long-term assets. We specify distribution boards with genuine spare capacity, battery systems with expansion slots, EV infrastructure with sub-board headroom for additional outlets, and solar inverters with headroom for additional strings. The decisions we make today are explicitly designed to accommodate the technology your household will adopt over the next decade - without requiring a complete reinstallation to absorb them.

How much solar generation can your roof realistically support? What battery capacity eliminates your overnight grid dependency? Can your current supply handle three EV chargers, a heat pump and a pool simultaneously - or does it need upgrading first? We answer these questions with data: your consumption history, your roof's solar irradiance profile, your peak demand curves. Accurate answers before any commitment. That is the standard of consultancy we bring to every property in Kingston, Teddington, Cobham and across the Surrey borders.

Every recommendation begins with your actual consumption data, not manufacturer default tables. Your investment is sized to your property's real profile - maximising financial return and avoiding oversizing that inflates cost without improving performance.
The engineer who models your energy system designs the installation and oversees delivery. No translation loss between a sales consultant and a subcontracted crew. Technical continuity from the first site visit to the final commissioning report.
NICEIC-registered for all electrical works, MCS-certified for solar installations, OZEV-compliant for EV charging. Every certificate is publicly verifiable. Your insurer, surveyor and prospective buyer can confirm our credentials independently.
Every system we install includes explicit expansion capacity: spare battery slots, sub-board headroom for additional EV outlets, inverter strings for future panels. The infrastructure you commission today absorbs your household's next upgrade without starting from scratch.
Delivering genuine energy independence across large suburban estates in Kingston, Teddington, Richmond and Surrey demands a different order of technical competence than standard domestic installation. These are the foundations we bring to every project at this scale.
A whole-house rewire in a large property is an opportunity to build the backbone for every system your household will ever deploy. We install structured cabling pathways that support smart lighting, AV distribution, security, HVAC control and future automation from a single riser - cleanly routed, correctly containment-rated and documented in a wiring schedule that future integrators can work from without pulling ceilings down to find out what was installed and where.

A single-phase 100A supply becomes a bottleneck the moment your home adds high-capacity loads simultaneously. We carry out a formal load analysis under BS 7671 diversity factors, calculate whether a three-phase upgrade is genuinely required or whether intelligent load management resolves the issue more cost-effectively, and - where an upgrade is warranted - manage the full process with your Distribution Network Operator from application through to energisation.
At the scale of a 20kWp solar system or a commercial-grade EV infrastructure installation, component quality is not optional - it is the difference between a fifteen-year asset and a five-year liability. We specify Schneider Electric distribution gear, SolarEdge or SMA inverters, Tesla or premium-tier battery storage, and Eaton or ABB protective devices. Every component is sourced through authenticated supply chains and its certificate of conformity is included in your handover documentation as standard.
Georgi Tangarov founded GThink Ltd on a precise observation: the most technically demanding residential properties in and around London were being served by either large utilities who treated them as volume jobs, or small domestic electricians who lacked the engineering depth the projects required. The answer was a practice built entirely around premium large-property work - with the technical rigour of a commercial contractor and the personal accountability of a specialist. Two decades of hands-on experience across complex solar installations, three-phase commercial-grade upgrades and estate-scale smart home commissions have validated that position. Every engineer we field is held to the standard those clients rightly expect.
Picture your Kingston or Cobham property on a clear July afternoon: the pool heater running from solar generation, both EVs charging from excess generation rather than the grid, the underfloor heating pre-warming from stored battery power, and the evening garden lighting sequence running on a schedule your household set once and never thought about again. The grid is connected - but largely irrelevant. Your energy costs are a fraction of your neighbours'. Your home's asset value has increased measurably. And the system managing it all was installed once, certified completely, and requires nothing from you beyond an annual service visit. This is what large-property energy engineering produces when it is done properly.

Heated pool filtration and heating systems can consume 6,000 to 12,000kWh per year - more than a typical household's entire electricity use. Solar arrays sized against this single load alone often produce the fastest payback period of any renewable system on a large property.
Many large properties do not need three-phase supply - they need intelligent single-phase load management. Before committing to a DNO application, a formal diversity analysis often reveals that smart scheduling of high-load circuits achieves the same outcome at a fraction of the cost and disruption.

The most common battery sizing error is specifying against peak panel output rather than overnight consumption. On a large property, this typically means significant underspecification. We size storage against your actual overnight demand profile plus a resilience margin - not the inverter's maximum DC input capacity.
We pull your smart meter consumption data, survey all high-load circuits, map outbuildings and assess every usable roof plane before writing a single line of specification.
Solar sizing, battery architecture, EV infrastructure, supply capacity and distribution upgrades are designed as a single coherent system - with a financial model showing payback range and a phased delivery option if preferred.
Large property works are sequenced to maintain habitation throughout. Outbuildings, garages and grounds works are coordinated within the same programme so your household experiences a single, managed intervention - not a series of repeated visits.
Every system is formally commissioned, performance-verified and certified - NICEIC for electrical works, MCS for solar, OZEV for EV. All documentation is packaged for your insurer, surveyor and any future occupier.
We provide ongoing monitoring configuration, annual service options and a retained as-built record. When your household adds another vehicle, expands the property or increases generation, the infrastructure we built accommodates it.
