I · Installation
Installation
Mounting, wiring, commissioning, handover paperwork.
Battery install and backup circuits
Battery location and ventilation
Where a domestic storage battery can be installed, including fire separation, ventilation, impact and environmental limits.
Off-grid switchover and circuit grouping
How to choose maintained circuits, transfer behaviour and load shedding for battery backup.
Retrofit battery storage
Adding storage to existing PV, meters and DNO approvals.
Whole-home backup changeover
The isolation, neutral, earthing and protection design behind safe whole-home battery backup.
EV charger installation
Charger cable routes and parking
How parking, accessibility, fixed wiring and charging-lead reach shape a safe home-chargepoint location.
EV chargepoint commissioning
The electrical, protective, control and handover checks that turn a fitted wallbox into a commissioned chargepoint.
EV charger PEN fault detection
Why an outdoor charger on PME needs an open-PEN protective measure, and how the options are selected and verified.
RCD protection for EV chargers
How AC and DC residual-current protection is selected for a home EV chargepoint.
Electrical readiness
Air-conditioning installation
Heat pump retrofit
Commissioning flow rates
How a heat-pump water circuit is purged, balanced and proved against its design flow, temperature difference and manufacturer limits.
Condensate drainage
How an air-source heat pump's rain and defrost water is collected and discharged without ice, damp or unsafe drainage routes.
Electrical supply for heat pumps
How the circuits, protective devices, supply capacity, DNO process and certification are designed for a heat-pump system.
Outdoor unit siting
How to position an air-source heat-pump outdoor unit for airflow, noise, drainage, refrigerant safety, access and structure.
Planning constraints for ASHP
The domestic permitted-development tests for air-source heat pumps across the UK and when an application or heritage consent is needed.
Radiator emitter upgrades
How existing and replacement emitters are checked room by room for a heat pump's design temperatures and hydraulic flow.
Replacing an old boiler
How to plan the change from a boiler to a heat pump across heat loss, emitters, hot water, services, removal and handover.
Solar PV installation
AC isolator placement
How inverter AC circuits are isolated for maintenance, including systems with storage and backup.
DC isolator placement
How PV DC switch-disconnectors are selected, configured and positioned without adding avoidable fire risk.
Firefighter PV isolation
What remains energised during a PV emergency, and how design, labels and the building fire strategy support responders.
Solar roof and electrical install
Flat roof ballast systems
How a non-penetrating flat-roof PV mounting system is designed for wind, sliding, roof load and membrane protection.
In-roof solar mounting
How roof-integrated PV replaces part of the weather covering, including kit compatibility, fire performance and weathering evidence.
PV commissioning pack
The handover bundle after a solar install: commissioning test results, certificates, warranties, monitoring and system documentation, and how to tell a complete pack from a thin one.
Roof hook and rail mounting
How an above-roof PV mounting system transfers load into a pitched roof without damaging its covering or weather performance.
Roof loading survey
What a pre-installation roof assessment must establish about structure, condition and solar PV loads.
Scaffold and roof access
How safe roof access and edge protection are planned for a solar installation, including when scaffold or another system is suitable.
