How It Works

From Enquiry To Installation In Five Steps

  1. 1

    Tell Us About Your Home

    A short enquiry form: your details, postcode and the services you're interested in.

  2. 2

    Talk Through Your Options

    A member of the team explains the payment and funding routes that apply to your property - and for many services, including solar, can give you an estimate on the call. No jargon, no pressure.

  3. 3

    Your Written Quote & Your Decision

    You'll receive a clear, itemised written quote. Happy to go ahead? Pay in full, or apply for finance through Ideal4Finance - always your choice, and never a requirement.

  4. 4

    Survey & Final Design

    Once your order is confirmed, we finalise the details. Depending on the service, this is completed remotely - as with our solar desktop survey - or with a home visit where it's genuinely needed. We'll confirm what applies when we speak.

  5. 5

    Installation, Aftercare & Support

    Work is carried out by our certified, insured installation teams, and we stay on hand afterwards, with support and guarantees explained up front.

How Applying Works

  1. 1

    Get Your Written Quote

    We put together a written, itemised quote for your work - for solar, this follows the estimate from your first call - so your finance application matches the real job.

  2. 2

    Apply Directly

    You complete the Ideal4Finance application yourself. We can guide you through it, but the application must be completed by you.

  3. 3

    Agree Your Terms

    If approved, you'll choose your loan term and payment dates and set up your Direct Debit before work is scheduled.

  4. 4

    Install & Sign Off

    We complete the work, and you sign a satisfaction note when you're happy.

Know The Difference

Finance And Funding Are Not The Same Thing

Paying Monthly (Finance)

A regulated credit agreement arranged through Ideal4Finance, repaid monthly over an agreed term, with 0% finance available on selected agreements. You'll always see the full terms before you commit, and every agreement is subject to status and a credit check at the application stage, not at enquiry.

Funded Routes (Grants & Schemes)

Some energy efficiency measures may be delivered through funded routes such as government-backed schemes. These are not consumer credit. Eligibility depends on your property and circumstances, and our team can check what you may qualify for.

Not sure which applies to you? That's exactly what the first call is for.

FAQs

Common Questions

No. Many customers choose finance because it allows them to spread the cost over affordable monthly payments rather than paying everything in one go. If a deposit is required, we'll make this clear before you proceed.
