Solar Finance Options 2026

Yes — 0% APR finance means you pay exactly the same total as if you had paid in cash. The difference is that instead of a single upfront payment, you make equal monthly instalments over the agreed term (typically 12–36 months). There are no hidden fees within the finance product itself, though some lenders require a small arrangement fee (typically £50–£100). We partner with a consumer credit-authorised finance provider to offer 0% APR terms — ask us for the current available terms at your quote stage.

Any credit application involves a credit check, which creates a soft or hard footprint on your credit file depending on the lender. A single application for solar finance with an MCS installer is unlikely to materially affect your credit score. The monthly payments, if made on time, can positively contribute to your credit history. The main risk is applying to multiple lenders simultaneously — multiple hard searches in a short period can reduce your score.

Wiltshire Council participated in the Solar Together collective buying scheme in 2022–2023, which provided group-buying discounts for Wiltshire residents. As of 2026, a new Solar Together round has not been confirmed for Wiltshire, though Bath & North East Somerset and South Gloucestershire have run their own iterations. The most significant current subsidy is the 0% VAT rate on residential solar installations, guaranteed until at least March 2027 — this represents a saving of approximately £600–£1,400 on a typical installation. See our grants guide for a full list of current incentives.

In most cases, yes — and this is one of the compelling aspects of financing solar. A 4kW solar installation costing £7,500 financed over 24 months at 0% APR produces monthly payments of approximately £313. The same system will save approximately £80–£120 per month in avoided electricity costs from day one (at 24–28p/kWh blended rate). The loan repayment exceeds the monthly saving during the finance period, but once the loan is repaid, the full saving flows to your household budget for the remaining 20+ years of the system's life.

Yes. 0% APR finance is available on combined solar and battery packages, not just solar panels alone. A solar-battery combination (4kW solar + 9.5kWh Sigenergy) typically costs £11,000–£13,000 and can be financed over 36 months. The monthly savings from a combined system (higher self-consumption, reduced import) are typically £120–£170/month, partially offsetting the monthly finance payment from day one.
