Solar on a rental — the landlord economics

Solar on a BTL doesn't work the same way as on your own home. The tenant gets the electricity savings, you bear the capital cost — but you also get capital allowances, an EPC uplift, and a more lettable property.

The two questions landlords ask us most: 'can I claim the capital cost against tax' (usually yes via the Annual Investment Allowance) and 'will it actually move my EPC band' (almost always yes, often a full band).

We're writing a proper landlord guide covering: capital allowances vs. wear-and-tear, EPC modelling (SAP vs RdSAP), MEES regulations and the 2030 EPC C floor, and worked numbers for typical 2-bed and 3-bed BTLs.
