Electrical design that respects the build
Support before the drawings become expensive to change
JDH helps developers and architects plan electrical and renewable energy infrastructure at the right stage. The aim is to protect the programme, reduce rework and make sure the finished property is safe, serviceable and ready for modern demand.
Advice on electrical layouts, consumer unit positions, service routes, external supplies, EV charging and renewable-ready infrastructure.
Works planned around trades, build stages, access, inspection points and the practical realities of live construction sites.
Testing, certification, commissioning records and clear documentation for homeowners, managers and building control routes.
What JDH supports
Electrical and renewable systems across the whole development
From a single bespoke home to a phased development, JDH can support the core electrical installation and the technologies that now sit around it.
New build homes
Electrical installations for individual plots, extensions, refurbishments and bespoke residential projects.
Developments and phases
Consistent electrical delivery across plots, phases and site programmes with clear communication.
Architect support
Practical input on layouts, equipment positions, plant space, cable routes and future serviceability.
Solar PV readiness
Roof space, cable routes, inverter positions and consumer unit capacity considered early.
EV charging infrastructure
Charge point routes, supply capacity and parking arrangements considered in line with project requirements.
External and communal areas
Lighting, power, outbuildings, gates, paths, parking areas and shared infrastructure planned properly.
Design and compliance considerations
Modern homes need more than sockets and switches
New homes now carry heavier electrical expectations: EV charging, solar PV, battery storage, garden rooms, heat pumps, smart controls and more connected living. JDH helps bring those requirements into the electrical design without losing sight of safety, budget or buildability.
Key planning questions
Early electrical input helps the design team make better decisions before walls close, routes disappear or service positions become awkward.
- Where should consumer units, isolators, inverters and controls sit?
- How will cable routes work across plots, garages, outbuildings and plant areas?
- What future demand should be allowed for from EV charging, solar PV and storage?
- What documentation will be needed at handover and for building control routes?
Regulation-aware support
JDH can support electrical work that needs to sit alongside Building Regulations, BS 7671 requirements, Part P considerations for dwellings and EV charging infrastructure requirements where they apply.
- Electrical installation, inspection, testing and certification.
- EV charging and cable route planning for new homes and parking areas.
- Solar PV and battery storage infrastructure considered before final finishes.
- Clear records that help the project move cleanly from site work to occupation.
Site infrastructure
Keep the electrical work aligned with the programme
Electrical installation has to land cleanly around other trades. JDH works with the build sequence, identifying what needs to happen early, what can wait, and what must be protected for inspection, testing and final handover.
Practical planning for cable routes, containment, boxes, equipment positions and future access.
Final equipment, testing, fault resolution and certification handled with the end user in mind.
Lighting, power, EV charging, garages, outbuildings and shared areas planned as part of the wider installation.
Project route
From design conversation to handover pack
Review
Plans, site requirements, plot types and future technologies are reviewed before the electrical route is fixed.
Design
Layouts, capacity, service routes and renewable-ready details are shaped around the build.
Coordinate
JDH works around build stages, other trades, access and agreed inspection or completion points.
Install
Electrical and renewable infrastructure is installed with disciplined workmanship and clear communication.
Handover
Testing, certification, commissioning notes and any future recommendations are provided clearly.
Renewable-ready homes
Build in capacity for how people actually live now
Solar PV, battery storage and EV charging are easier to support when the electrical design allows for them early. JDH can help avoid the common problem of treating renewables as an afterthought once the property is already finished.
Plan cable paths, inverter locations and consumer unit capacity before finishes restrict access.
Consider parking positions, cable runs, load requirements and future charger installation from the outset.
Leave installations understandable, accessible and easier to maintain after occupation.
