Exagen Group

Exagen Group 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).

MCS certification is the industry standard for UK solar installers. Check the live MCS register at mcscertified.com — search by company name. If Exagen Group is currently MCS Certified, their name and certificate number will appear. If not listed, ask why.

RECC (Renewable Energy Consumer Code) and HIES (Home Insulation & Energy Systems) are the two main consumer protection codes for UK renewables installers. Check the RECC register at recc.org.uk or HIES register at hies.co.uk by company name. Membership of either gives you escalation routes and deposit protection.

Most reputable UK installers — including most London-area firms — offer a free desktop survey followed by a paid or no-cost roof inspection. Exagen Group's specific policy isn't published on EnergyRanked; ask when you make initial contact (their website exagen.co.uk is a useful starting point). A red flag would be any installer quoting without ever physically seeing the roof or property.

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.
