Frequently asked questions
What UK grants or schemes apply to a solar install with Tethys Energy?
Current UK support includes 0% VAT on residential solar PV and battery installs (HMRC zero-rating until at least 2027), the Smart Export Guarantee paying for exported electricity, and — for heat pumps — the Boiler Upgrade Scheme (England/Wales) or Home Energy Scotland Grant + Loan (Scotland). Eligibility depends on the property and the install. Confirm with Tethys Energy which apply before signing.
Is Tethys Energy MCS Certified for solar PV?
MCS certification is the industry standard for UK solar installers. Check the live MCS register at mcscertified.com — search by company name. If Tethys Energy is currently MCS Certified, their name and certificate number will appear. If not listed, ask why.
Does Tethys Energy cover areas outside Reading?
Many Berkshire-based installers cover a 20–40 mile radius from their base. Tethys Energy's exact catchment isn't published on EnergyRanked — ask directly. Distance affects scheduling and travel charges; an installer 90 minutes from your property may quote more for the same work than one 20 minutes away.
How does Tethys Energy's quote process work?
Tethys Energy typically begins with an initial enquiry via phone or website, followed by a desktop assessment and on-site survey. Ask whether the quote is fixed-price or estimate-only, and confirm what's included (scaffolding, DNO application, commissioning).
When is the best time to book a solar install with Tethys Energy?
Demand peaks April–August across the UK. Booking in autumn or winter often means shorter waits and sometimes pricing flexibility. Installation itself is a year-round activity in most UK weather — the constraint is scheduling, not the season.
