Add Battery Storage to Your Feed-in Tariff Solar — Without Losing Your Payments
Keep Your Feed-in Tariff. Cut Your Energy Bills. Add Battery Storage Safely.
If your solar panels were installed under the UK Feed-in Tariff, you can add battery storage — when it’s done correctly.
Mr Solar specialises in FiT-safe battery upgrades that protect your income and maximise your solar use.
The Problem
Many homeowners on the Feed-in Tariff: 
-
Export valuable solar energy for very little return
-
Buy expensive electricity back in the evening
-
Are told adding a battery will cancel their FiTs payments
That fear stops thousands of people upgrading — unnecessarily.
The Truth About Batteries & Feed-in Tariffs
✔ Ofgem allows battery storage to be added to Feed-in Tariff systems
✔ Your FiT payments remain unchanged
✔ The system must be designed so only solar generation is measured
When installed correctly, battery storage:
-
Stores your excess solar
-
Reduces grid imports
-
Keeps your Feed-in Tariff fully intact
Why Experience Matters 
Most installers today:
-
Focus on new solar installs
-
Don’t understand FiT-era metering
-
Risk invalidating your tariff through poor design
Mr Solar specialises in older systems.
We design battery upgrades that work with your existing FiT installation — not against it.
