Household savings scenarios (verified, conservative)
Verification-first Savings scenarios are constrained to source-backed claims. We do not publish invented savings figures.
Verified core input: Octopus referral credit is £50 (eligibility and terms apply).
Formula used: Year-1 expected impact = £50 + tariff-cost difference.
If tariff comparison data is missing, the only safe minimum shown is the verified referral-credit component.
Scenario A — Low-use household (1–2 people, flat/small home)
Usage profile: 1,800 kWh electricity + 7,500 kWh gas (Ofgem low).
Baseline annual cost reference: ~£1,189.55 (Ofgem Apr–Jun 2026 average cap rates).
Verified minimum year-1 component: £50 referral credit (if eligible).
Expected impact framing: £50 + tariff-cost difference on like-for-like assumptions.
Scenario B — Medium-use household (2–3 people, typical home)
Usage profile: 2,700 kWh electricity + 11,500 kWh gas (Ofgem medium).
Baseline annual cost reference: ~£1,641.18 (aligned with Ofgem ~£1,641 typical annual benchmark).
Verified minimum year-1 component: £50 referral credit (if eligible).
Expected impact framing: £50 + tariff-cost difference on like-for-like assumptions.
Scenario C — High-use household (4–5 people, larger home)
Usage profile: 4,100 kWh electricity + 17,000 kWh gas (Ofgem high).
Baseline annual cost reference: ~£2,302.26 (Ofgem rate model).
Verified minimum year-1 component: £50 referral credit (if eligible).
Expected impact framing: £50 + tariff-cost difference on like-for-like assumptions.
Assumptions and caveats
- Referral credit depends on Octopus referral eligibility and terms.
- Tariff savings depend on current supplier, region, payment method, meter type, and usage.
- Ofgem cap rates are GB averages for Apr–Jun 2026 and can change quarterly.
- No universal personal-savings claim is made beyond the verified referral-credit component.
Verified gas-saving example 1 — Lower thermostat by 1 C
Safe wording (confidence: Medium-High): If your home still feels comfortable, lowering your thermostat by 1 C can reduce heating energy use noticeably. A UK smart-meter analysis in gas-heated homes found each 1 C lower setting (between 22 C and 18 C) was linked to around £130 less annual energy use for a typical 85m² home, based on the Oct 2022 price cap.
Caveat: This is not a guaranteed saving for every household. Results vary by insulation, home size, weather, heating schedule, and tariff. Keep healthy indoor temperatures (typically 18–21 C).
Verified gas-saving example 2 — Lower combi boiler flow temperature to 60 C or below
Safe wording (confidence: High action relevance / Medium-High £ estimate): If you have a combi boiler, reducing radiator flow temperature to 60 C or below can improve efficiency and cut gas use. UK consumer guidance linked by Ofgem indicates average savings around £65/year (Sept 2023 price basis).
Caveat: Applies to condensing combi boilers; not universally applicable to all systems. If rooms do not heat adequately, raise setting slightly.
What is not claimed
