What Solstice Energy does

Solstice Energy Ltd. is a UK-based solar photovoltaic (PV) installation contractor founded in 2003 and headquartered in Alton, Hampshire. The company designs, supplies, installs, and commissions PV systems for three customer segments: domestic (1–4 kWp), community (5–18 kWp, including churches and public buildings), and commercial buildings (up to 30+ kWp). It also supplies grid-connected battery storage packages and a proprietary mounting solution — the Lead Roll Clamp — designed for historic and listed buildings and released under an open GNU licence. Solstice holds MCS, NICEIC, RECC, SafeContractor, and QANW accreditations, enabling self-certification under Part P and access to government incentive schemes.

The business operates a sales-led, direct-installation model with a free no-obligation design and quotation process followed by a site survey. Revenue is generated through one-time professional services and hardware sales (PV modules, inverters, mounting equipment, and battery storage), with the company remaining supplier-agnostic across tier-1 brands. Domestic systems are priced at £4,000–£10,000 and battery packages at £2,000–£7,000. The company is privately held, founder-operated, and reports approximately 90% of current work is repeat business from construction and M&E companies, with documented customers including Willmott Dixon, Midcounties Co-operative, and Alphega Design. Solstice is currently restricting new work to commercial clients, ground-mount systems, and domestic new-builds due to capacity constraints relative to demand.

Expansion highlights4 records

Broad incumbents

• EDF Renewables UK: Subsidiary of EDF operating utility-scale and distributed solar plus battery storage across the UK. Overlaps Solstice in commercial/rooftop solar but operates at vastly larger scale and with utility backing.
• Solarcentury (Statkraft): One of the UK's largest and most established solar EPC firms, now owned by Statkraft, operating across utility-scale, commercial and residential segments. Comparable solar installation offering but at materially larger scale than Solstice.
• Statkraft UK (Solar Development): Norwegian state-owned renewable energy developer with growing UK solar and battery portfolio. Comparable underlying technology and project delivery but operates as a large developer rather than regional installer.

Direct peers

• Joju Solar: UK solar PV and battery storage installer serving community buildings, schools, churches and commercial clients with funding application support. Directly comparable mission and customer segments to Solstice Energy's community/listed-building focus.
• Cotswold Energy Group: Mid-sized UK solar and battery storage installer covering domestic, commercial and community projects with funding assistance. Directly comparable offering and customer mix.
• Eco2Solar: UK-based solar PV installer offering design, supply and installation of rooftop and ground-mount systems for residential, commercial and new-build housing developers. Closely comparable business model to Solstice Energy with similar B2B/developer focus.
• RE:GEN Group: UK solar and renewables installer active in domestic, commercial and community installations including faith and heritage buildings. Comparable service mix and target customers to Solstice Energy.

Others

• Good Energy: UK renewable electricity supplier already partnered with Solstice on community PV installations; adjacent ecosystem participant that buys export from small-scale generators and competes indirectly in domestic renewables.

Regional players

• 1st Light Energy: UK solar PV installer focused on commercial rooftops, ground-mount and battery storage for SMEs. Comparable offering and customer base to Solstice Energy in commercial and ground-mount segments.

Emerging players

• Octopus Energy (Solar & Heat): UK energy retailer that has expanded into solar PV and battery installation for residential and SME customers, leveraging its customer base. Comparable residential offering but with structural advantages Solstice lacks.
