When you buy a new-build home with solar panels, you almost always own them outright as part of the property — this is the usual model on new homes built for sale. But ownership of the panels and the right to the export payments are two different things, and the second one trips up a surprising number of new-build buyers.
Do you own the solar panels on a new build?
In the overwhelming majority of private-sale new builds, yes. The panels are part of the building fabric, conveyed to you with the freehold or leasehold like the roof itself. A small number of social-housing and Build-to-Rent schemes use a third-party PPA (Power Purchase Agreement) model where an operator owns the array and sells you the electricity — but for a private-sale new build you own the system.
Who gets the Smart Export Guarantee (SEG) payments?
This is the question to nail before completion. The SEG pays you for surplus electricity exported to the grid (typically 4-15p/kWh). To claim it you need the system registered to you with a valid MCS certificate in your name and an export meter. The trap: some developer installs are registered to the developer or left unregistered, which can block or delay the buyer's SEG claim. Our new-build solar incentives guide explains the MCS-SEG link in detail.
What to confirm with your housebuilder
Before exchange, get written confirmation of four things: (1) you own the PV system outright; (2) the MCS certificate will be issued in your name at handover; (3) you receive the SEG export payments; and (4) the panel and inverter warranties transfer to you. These cost the developer nothing to confirm but materially affect the value you get from the system over 25 years.
Does owning the panels add value when you sell?
Yes — owned solar (versus a PPA-encumbered system) is cleaner at resale and contributes to the EPC A/B rating that FHS-compliant new builds achieve, which increasingly unlocks green-mortgage products for your buyer. A PPA arrangement, by contrast, transfers with conditions and can complicate conveyancing. For the full financial picture see our new-build solar finance guide and ROI calculator.
