Honestly, nobody can give you a guaranteed number here. House prices move on all sorts of things and solar is only one of them. What we can say is that a properly installed system tends to be treated as an asset rather than a quirk, and that's been changing fast as energy prices stayed high.
Buyers understand that a solar system means lower running costs from day one, and a system that comes with full paperwork reassures them it was done right.
What makes the difference — An MCS-certified installation with proper documentation adds the most value. This includes your MCS certificate, your Smart Export Guarantee registration, and evidence of system performance. We provide all of this as standard.
EPC rating boost — Solar panels typically improve your Energy Performance Certificate rating by one or two bands. A better EPC rating is increasingly important for property sales in Scotland and can influence mortgage lending decisions.
The system also continues earning through the Smart Export Guarantee, paying you 5-15p per kWh for electricity exported to the grid. That ongoing income is transferable to the new owner.
