Frequently Asked Questions
What does a motorhome electrical installation include?
A motorhome electrical installation includes the installation, wiring, configuration, testing, and commissioning of a complete off-grid electrical system. This typically covers leisure batteries, inverters, solar charging, alternator charging, shore power integration, AC and DC distribution, protection devices, and system monitoring.
As every motorhome and usage profile is different, installations usually begin with a system design consultation to ensure your off-grid requirements are properly understood and catered for.
Are you a Victron certified installer?
Yes. Tiny Build Electrics are a Victron Energy Certified Installer. All motorhome electrical installations are upgraded using Victron systems, as well as other high quality components which are installed, configured, and tested correctly to provide safe, reliable, and well-supported off-grid power.
Why do you only install Victron systems?
Victron Energy systems are proven, well-documented, and designed for complex off-grid electrical installations. By specialising exclusively in Victron systems, we can ensure motorhome electrics are installed correctly, configured accurately, and supported long-term without compromising safety, performance, or reliability.
Are motorhome electrical installations tested and compliant?
Yes. Every motorhome electrical installation is fully tested with electrical safety and compliance as the priority. Installations follow best practice and relevant UK electrical standards, including applicable elements of BS7671, providing confidence for insurance, resale, and long-term use.
Where are motorhome electrical installations carried out?
All motorhome electrical installations are carried out at our Cumbria workshop. Working in a controlled environment allows us to maintain consistent installation quality, carry out thorough testing, and ensure systems are fully operational before handover.
Are your electrical installations certified and compliant?
All systems are designed and installed with safety and BS7671 compliance as the priority. Installations are thoroughly tested and documented, providing peace of mind for insurance, resale, and long-term reliability.
How much does a motorhome electrical installation cost?
Motorhome electrical installation costs vary depending on system size, components, and existing vehicle infrastructure. Pricing is influenced by battery capacity, solar setup, inverter size, charging methods, as well as if the work is a full installation or an upgrade to an existing system. Final costs are confirmed once the system design is agreed.
Do I need a system design consultation before booking an installation?
In most cases, yes. A system design consultation ensures the system is correctly specified before installation begins. This helps avoid incorrect or incompatible components, delays, or changes once the motorhome is in the workshop and ensures the system matches your real-world power needs.
Can you work on older or pre-owned motorhomes?
Yes. We regularly work on older and pre-owned motorhomes, assessing existing electrical systems and upgrading them where appropriate. This can include leisure battery upgrades, inverter upgrades, and replacing or adding additional solar panels, with all work carried out safely and in line with current electrical standards.
Can you install solar panels, lithium batteries, and inverters in a motorhome?
Yes. We can install additional motorhome solar panels, upgrade lithium batteries, inverters, and charging systems as part of a complete electrical installation. All components are integrated and configured to work together efficiently and safely as a single system.
Can you upgrade or modify an existing motorhome electrical system?
Yes. We can assess and upgrade existing motorhome electrical systems where appropriate, including leisure battery upgrades, inverter upgrades, and improvements to charging performance. All upgrades are carried out with safety, compatibility, and system integrity in mind.
Do you provide support after installation?
Yes. We provide ongoing support after installation, helping with system operation, future upgrades, and general off-grid electrical questions once your motorhome is in use.
