Website for solar and heat pump installers: cost and what it needs

en 2026-09-29 7 min read

A solar or heat pump installer that wants homeowners in its region to research, compare and request a quote online fits step 03, a business website at EUR 1.500 to 3.500, built in 3 to 6 weeks. Booking a survey visit is part of that; booking that reads your planning software through an API, a calculator fed by another service, or payment taken online is step 04 at EUR 3.500 to 7.500.

How an installer's site wins or loses a request

A homeowner buys a large installation on or in their own house before seeing it work, so they judge what surrounds it. Does this system suit my house? What happens during installation? Will anyone answer once the installer has left? A site that answers those in plain words earns the request.

Suitability is specific to the house. Panels depend on the roof, its orientation and shading. A heat pump depends on how well the house holds heat and how it is heated, and hybrid and all-electric systems suit different houses. A site that skips this and leads with savings invites requests from houses it cannot help, and a form that asks for nothing means the survey visit is spent on basics.

What the site needs to carry

A page for each system you install

Solar panels, batteries, hybrid or all-electric heat pumps, charging points: give each one you install its own page, explaining what makes a house suitable and what the work involves.

Your service area, in words

Name the municipalities and regions you cover, and ask for a postcode early in the form so a request from outside your area gets an honest answer instead of silence. Give a town its own page only where you have installed there and have something specific to say.

Subsidies, in general terms

Subsidy and energy rules for homeowners change, and a page that repeats last year's amounts misleads the reader who trusts it. Say in general terms that support may exist for certain installations, say whether you help with applications, and link to the official government information for current amounts and conditions.

Proof from your own work

Show photographs of your own installations, the brands you install, the warranty terms you give, the certifications you hold and reviews from homeowners who agreed to be quoted. A stock photo of a roof says nothing about your roofers, a point stock photos versus real photography takes further.

The route from request to installation

Set out the steps: request, survey visit, quote, planning, installation day and aftercare. Say what the homeowner should have ready, such as annual energy use or a photograph of the meter cupboard, and what happens in the house on the day.

The text, photographs and project descriptions have to exist before the pages are finished. That part waits on you.

What moves the quote

• Systems and towns with their own page. Step 03 covers 4 to 7 pages and each extra simple page is an add-on at EUR 150 to 250, so keep the list to those with something true to say.
• A project gallery. Installations in the CMS, filtered by system and town, need their own template and someone at your company to add each job.
• Booking. A homeowner picking a survey slot is step 03. Booking that reads live availability from your planning software through an API is step 04, as adding a booking system explains.
• Calculators. A sizing or savings tool that pulls data from another service through an API is step 04. Every figure it shows reads as a promise, so decide first whether you want to make one.
• Your systems and payments. Your CRM's own embeddable form fits step 03. Requests sent into a CRM or planning system through an API, or payment taken online, is step 04.

Which step fits which installer

The full ladder is on the packages page. For an installer it maps like this.

Process and timeline

1. Scoping. Pages, quote form questions, how subsidies are mentioned and where each request lands. A fixed quote follows.
2. Content. System text, the service area and project photographs. This waits on you.
3. Structure and design. The path from first question to request, handled as one job under design and engineering.
4. Build. Templates, a CMS collection for projects, forms and booking.
5. Testing. Every form and booking route tried on phone and desktop, including a postcode outside your area.
6. Launch and handover. CMS access for your team to add projects and edit pages.

Step 03 runs 3 to 6 weeks and step 04 runs 6 to 12 weeks. Where your project lands inside its range depends on when the content arrives.

Ownership, care and search

You own the code, the repository and the database. We can host the site too, agreed per project. Care runs EUR 100 to 300 per month for updates, monitoring, backups and small fixes, not a redesign or new features.

SEO foundation is a one-off EUR 450 to 750 for Search Console, analytics, indexation, technical hygiene, titles, internal links and a 3 to 6 month plan. SEO growth at EUR 500 to 800 per month carries that plan out with technical and on-page work, service and location pages, internal links and authority, and reporting. For an installer, the location pages worth writing are the towns you actually work in.

When to spend less

If your planning is full for months from referrals, the site is where homeowners check you, not where they find you. A step 01 page at EUR 600 to 900 or a step 02 mini-site at EUR 900 to 1.500 does that job, and SEO growth would chase requests you could not schedule.

If you install as a subcontractor for other installers or energy companies, the homeowner meets their brand, not yours, and a single page for partners and vacancies is enough.

In both cases SEO foundation, done once, still sets up indexation and measurement properly. Do not buy a bigger build yet.

Questions installers ask

Should we publish prices?

A system price depends on the house, so a single figure can mislead. If you can stand behind example configurations with a from-price, they help a homeowner decide whether to ask. Either way, explain what goes into your quote.

Should subsidy amounts be on our site?

Mention support in general terms and link to the official source for amounts and conditions. Figures copied onto your own page go out of date, and a homeowner who planned around them may hold you to them.

Can homeowners book a survey visit online?

Yes. Booking a visit is part of step 03 at EUR 1.500 to 3.500. If the slots should come from your planning software through an API, or the visit is paid for at booking, that is step 04 at EUR 3.500 to 7.500.

Who adds new projects to the site?

Your team, in the CMS, without a developer: photographs, the system, the town and a short description. Care keeps the site updated, monitored and backed up, but adding projects is something you do yourself.

Tell us the systems you install, the area you cover and where requests should land, and we will scope it and quote a fixed price. Start here.
