In their own words
. * Our overall emissions have decreased by 7% from 2024 with a reduction across Scopes 1, 2 and 3.. The largest fall has been reported on our company vehicles, as we are now changing over to electric only vehicles. We hope to reduce this further as current contracts end. We have decreased our electricity usage further by setting automatic switch offs on our lighting within the office to a shorter period. By holding meetings on Teams instead of travelling out of the office, we have also seen a decrease in land travel. Staff are encouraged to cycle, walk or take public transport and we offer the Cyclescheme to all employees. Due to the increase in international project work, we are having difficulty in reducing business travel by air and hotel accommodation. We promote train travel to Europe instead of taking flights where possible.

Renewable transition options· 219 MWh annual load · 100% renewable today

What it would realistically take to move 0 MWh of remaining electricity to renewable sources, given typical SME options + market-specific costs in this country. Numbers are indicative — a real proposal needs a quote from a local installer or supplier.

Switch to certified renewable tariff
Not feasible
Most cost-efficient route for this load.

Sign with a green-energy supplier (Guarantees of Origin / REGOs backing). No capex; pricing is tied to a small premium over your current standard tariff. Best when paired with on-site reductions to keep total bill manageable.

Annual cost
£0–£0
Effort
low
Already on 100% renewable.
On-site rooftop solar (~231 kW)
Not feasible
Capex investment that covers ~100% of current consumption.

Install a 231 kW rooftop PV system (sized to match annual consumption). Yields ~219 MWh/year in GB — close to total annual use. Net-metering / export tariff supports the payback. Real proposal needs a roof survey + planning check.

Annual saving

Payback

Effort
high
231 kW exceeds typical SME rooftop area; consider a ground-mount or PPA route.
Aggregated / community PPA
Possible
Pool with other small users to access wholesale renewable generation.

Several brokers (e.g. SmartestEnergy, Statkraft, Centrica) now offer aggregator " + "PPAs that pool SMEs to reach the ~5 GWh/year minimum. Typical contract length 5–10 years. Pricing usually below standard tariff; protects against grid-tariff inflation.

Annual cost
£0–£0
Effort
medium
Volume just about supports aggregator pooling.
Direct corporate PPA
Not feasible
Not feasible at this consumption volume.

Direct PPAs require a buyer to commit to ~5–50 GWh/year over 10+ years. Any SME at <100 MWh annual consumption can't access this market directly. Out of scope for this firm.

Direct PPAs require ≥1 GWh/year; this firm uses ~219 MWh.

Cost ranges are 2025-ish published market data. Premiums + capex move with energy prices and policy. Best approach for most SMEs: certified renewable tariff first (cheap, fast), then on-site solar if roof + capital allow. PPAs need ≥1 GWh/year volume to access directly — aggregators are starting to bridge this for smaller users.

Sector net-zero pathway· construction

Industry-level decarbonisation context — not this firm's own commitment. Shows how the wider sector needs to evolve for individual SME targets to be achievable.

Construction emissions are dominated by upstream cement + steel; building operational emissions follow the buildings pathway.
