Solar & Renewables web development in London: FAQs

How much does a solar & renewables website cost in London?+

In London, a business website typically costs £5,000 – £20,000, while a custom web app runs £20,000 – £120,000. Agency day rates of £600-£1,500/day are the main driver, followed by integrations and how much custom functionality you need. Tecklogist quotes solar & renewables projects from from £799 at a fixed price.

How long does it take to build a solar & renewables website?+

A business website usually takes 3–6 weeks; a custom web app takes 8–20 weeks. Delays almost always come from late content, unclear scope or third-party integrations, so agree those before work starts.

Which platform is best for solar & renewables websites?+

The usual options are WordPress with custom ROI calculator and Next.js for enterprise solar companies. The right one depends on how often your team edits content, which systems the site must connect to and your budget, so be wary of any London agency that recommends the same platform for every client.

What should I ask a solar & renewables web developer in London before hiring?+

Ask about rOI/savings calculator; accreditation badges with verification links; case study pages with before/after bills, system size, installation timeline, and verified Google review. Then ask for two or three live solar & renewables websites they built, who will actually work on yours, and what support looks like after launch.

Why is Tecklogist ranked first on this list?+

This list is published by Tecklogist, and we rank ourselves first because solar & renewables websites are core work for us: fixed prices, fixed timelines and code you own. The other London agencies are ordered by the solar & renewables evidence in their public profiles, and none of them pay to appear.
