Measurable Campaign Delivery for Clean Energy Contractors
Target the right properties, not just the postcode
A solar or heat pump campaign works best when it reaches properties that fit the offer. We can help refine your mailing data using criteria such as suitable roof space, grid connection requirements and lower EPC ratings. This gives your campaign a clearer focus and helps you reach households and businesses more likely to switch.
Give your print campaign a stronger environmental story
For businesses promoting solar, heat pumps and other low-carbon technologies, the environmental credentials of their marketing materials matter too.
Through our partnership with the World Land Trust, eligible print campaigns can benefit from Carbon Balanced print, with the associated carbon footprint measured and balanced through conservation projects. It gives you a credible way to explain the environmental considerations behind your printed marketing and the products and services you're promoting.
Reaching your Market: B2B Commercial Contracts vs Domestic Retrofits
Every renewable campaign requires a customised approach. We tailor our services to match your exact target market:
B2B data matched to suitable commercial properties
Commercial energy campaigns work best when they reach businesses with the right premises and the potential to invest. We help you target relevant organisations using business data filtered by factors such as industry sector, property type, site size and ownership where reliable data is available. This helps you focus your outreach on businesses that are a better fit for your solar, HVAC, or energy-efficiency solutions, rather than spending your budget contacting companies unlikely to need them.
Door drops targeted to the right housing stock
Not every property is suitable for solar panels or a heat pump, so targeting the right areas matters. We help you plan door drop campaigns around residential postcode sectors that are more likely to contain suitable homes, from off-grid properties that may benefit from heat pumps to homes with suitable roof space for solar panels. Where relevant, EPC ratings can also help inform targeting for energy efficiency schemes, although eligibility for funding such as ECO4 depends on the scheme's specific criteria. This helps you focus your campaign on the households most likely to benefit from your offer.


Responsible Production: Certified Carbon Balanced via World Land Trust
Physical marketing must be backed by credible, auditable environmental action rather than broad environmental claims:
Audited Carbon Balancing: Working through our Greener Mail initiative, the unavoidable carbon footprint of your campaign’s paper and production is measured and balanced through the World Land Trust.
Permanent Habitat Preservation: Every campaign funds the preservation of high-conservation-value forests, directly protecting endangered ecosystems and wildlife habitats.
Chain-of-Custody Paper Stocks: We print exclusively on FSC-certified, responsibly managed virgin or recycled pulp.
Compliant Evidence: We supply campaign-specific Carbon Balanced certificates and registered logos for inclusion in your creative artwork, giving your prospects clear, third-party verified proof.
Don't waste budget guessing. Tell us the tech you're installing and the areas you cover, and we’ll run a free counts report showing eligible domestic rooftops or commercial sites ready to mail.

FAQ
Carbon Balanced Print calculates the carbon impact of the paper substrate and production processes, then offsets those emissions by funding the protection of threatened forests through the World Land Trust.
Yes. You can filter commercial direct mail data using criteria such as premises type, ownership status, building size, and geographic location to identify facilities suited for commercial solar or biomass heating.
Domestic retrofit leaflets can be distributed through unaddressed door-drop campaigns using services such as Royal Mail’s door-to-door network
Campaigns can focus on selected postcode sectors, helping you reach households in areas where the housing stock and local characteristics match your offer. The coverage and targeting options will depend on the distribution service you choose.
