Question 1

How much does energy marketing cost in the UK?

Accepted Answer

Cost varies sharply by sub-sector. Retainers for a specialist B2B energy or renewables agency typically sit between £3,000 and £15,000 per month for ongoing brand, content, PR, and digital support, with mid-market integrated programmes commonly £5,000 to £10,000 monthly. Installer lead generation (solar, heat pump) tends to run on a performance basis once volumes are proven, with cost per qualified lead ranging from £40 to £150 depending on tech, region, and MCS-directory routing. A national supplier-acquisition push is a different order of magnitude: Octopus more than doubled its marketing spend to £88m in 2024 to support a market-leading 24% retail share. Agency fees for a network-led supplier campaign with creative, paid media, and CRM commonly land in the £500,000 to several-million range for a major push, and most of the spend goes to paid media rather than agency time.

Question 2

What rules apply to green energy claims in UK marketing?

Accepted Answer

Two regulators sit on top of green energy claims. The ASA enforces Section 11 of the CAP Code, which requires absolute claims like 'green', 'eco-friendly', 'carbon neutral', or '100% renewable' to be substantiated against the full product lifecycle and qualified where the basis is anything narrower than the company's total activity. ASA guidance is aligned with the Competition and Markets Authority's Green Claims Code, and the ASA has run a sustained enforcement programme on energy majors since 2022, with upheld rulings against Shell, Repsol, Petronas, and TotalEnergies, plus 2025 bans on British Gas and Hive heat pump and solar adverts for inadequate savings substantiation. The well-known loophole on 'green tariffs' (suppliers buying REGOs to match brown power with renewable certificates) is now explicitly in the ASA's sights, with the 2023 Shell ruling holding that consumers would interpret a '100% renewable electricity' claim as referring to the supplier's whole activity, not just the certificate-matched portion. Any energy advertiser needs a substantiation file ready before launch.

Question 3

How long does energy marketing take to show results?

Accepted Answer

Three timelines run in parallel. Performance-led installer lead generation (solar, heat pump) can show CPL and conversion signal inside 4 to 8 weeks once tracking is in place, though BUS voucher-to-installed conversion takes 3 to 6 months because the installer-led application and installation window runs up to 3 months from voucher issue (6 months for ground-source). Supplier acquisition and retention work moves faster on paid channels (switching peaks around price-cap announcement weeks every quarter) but brand-led trust rebuild after the 2021-2022 supplier failures is a 12 to 24-month effort measured through tracker work (Kantar, YouGov BrandIndex, Trustpilot, Which? rankings). B2B energy-services and corporate-PPA sales cycles are the slowest of all, with typical 6 to 18-month sales cycles for industrial and commercial buyers, where consistent presence in trade press (Utility Week, Current News, Energy Live News) and analyst coverage matters more than short-term paid response.

Question 4

Should I hire an energy specialist or a generalist agency?

Accepted Answer

It depends on where the regulatory and credibility risk sits. If the brief is a licensed-supplier campaign, a green-tariff launch, a retrofit-installer programme that needs to clear MCS, or anything where ASA pre-vet matters, a specialist with named energy work on the case study page is the right call. Specialists like Aspectus, Wildtribe, Motion Marketing, EKC, and a handful of others have lived inside Section 11 of the CAP Code, the Boiler Upgrade Scheme rules, and the Ofgem Standards of Conduct, and the cost of getting these wrong (an upheld ASA complaint, an Ofgem investigation, a withdrawn campaign at peak switching season) is high. If the brief is a non-licensed adjacency (sustainability consultancy, B2B SaaS for the energy sector, fleet-electrification services without direct EV charging operation), a strong B2B or sustainability generalist with credible energy clients can be the more economical choice. The diagnostic question in any pitch is whether the team can name MCS, TrustMark, the Boiler Upgrade Scheme grant amount, and the ASA's 2025 line on 'save up to' heat pump claims without prompting.

Question 5

How does MCS or TrustMark certification affect installer marketing?

Accepted Answer

MCS certification is the gate to most consumer-renewables marketing in the UK. Any installer that wants to fit solar PV, heat pumps, biomass, or small wind under government grant schemes (Boiler Upgrade Scheme, Smart Export Guarantee) must be MCS-certified, and the Boiler Upgrade Scheme application is installer-led, meaning the installer applies for the £7,500 grant on the homeowner's behalf. MCS members are listed in the public installer directory and most consumer comparison platforms (Which? Trusted Traders, Checkatrade, TrustMark) filter on MCS status, so the certification is itself a marketing channel. MCS membership is conditional on registration with a Trading Standards Institute-approved consumer code: RECC (Renewable Energy Consumer Code), HIES (Home Insulation and Energy Systems Contractors Scheme), or GGF, and these codes start with a marketing rule: no misleading claims, no high-pressure selling, no inducement to force quick buying decisions. TrustMark registration sits on top as the government-endorsed quality mark, and the combination is what gives an installer brand the credibility to convert a high-consideration, £8,000 to £15,000 ticket size.
