Indicative 2026 tariffs for offices & workplaces range 13–18 p/kWh. The lower end applies to investment-grade off-takers on 25-year contracts with strong daytime self-consumption; the upper end applies to smaller systems or shorter terms. Our PPA calculator models your specific site.
From first call to commissioning typically 6-12 months. Indicative tariff in 2-4 weeks, site survey + heads-of-terms in 4-8 weeks, full contract in 8-12 weeks, build in 6-16 weeks. Larger systems with DNO upgrades take longer.
Typical 2026 systems for offices & workplaces range 50–500kWp. Smaller sites stack with battery storage; larger sites may split across rooftop + ground-mount or multi-site sleeved structures.
For public-sector sites, PSDS often gives a lower lifetime cost — but with lengthy procurement and 100% utilisation requirements. For energy-intensive industry, IETF stacks. For most commercial buyers, PPA wins on cashflow and admin simplicity. See PPA vs grant-funded.
Most providers want investment-grade or strong-unrated covenant. For weaker covenants, parent guarantees, letters of credit, or shorter contracts can bridge. See off-taker covenant deep-dive.
