Customer profiles and applications

The company adapts its designs to different environments. For residential homes it offers custom engineering and aesthetic integration. In the commercial and industrial sector it develops large-scale rooftop solar installations for businesses. For new builds and developers it offers turnkey solutions that comply with Part L for housing schemes. It also serves the public and school sector with carbon-reduction infrastructure, and the agricultural and rural sector with barn-roof arrays and multi-building systems for farms.

Funding and payment options

REST UK offers several funding routes for its installations. The company acts as a credit broker, not a lender, and financing is arranged through authorised, FCA-regulated entities such as Tandem Bank, thisbank and Propensio Finance. Options include 12-24 month 0% interest finance, 36-60 month terms with a representative APR of 8.9%, and extended terms of up to 240 months with the same representative APR. There is also a solar subscription option with no upfront cost and a fixed monthly fee, and lease-to-buy options of up to 300 months with no upfront payment, with ownership transferring at the end of the contract subject to the provider's terms. The company states that financed purchases may benefit from UK consumer legal protections, including Section 75 where applicable. As a representative example, it mentions an £8,000 loan over 60 months with a representative APR of 8.9%, a monthly payment of £165.68 and a total amount repayable of £9,940.73.

Accreditations and customer protection

REST UK holds MCS, HIES, EPVS, RECC and FCA accreditations, which the company describes as independently verifiable. The company highlights two protection mechanisms: HIES, focused on customer protection and dispute support, and EPVS, which validates performance estimates before signing. These checks apply at three points: before signing, during the project (with deposit protection and staged payments) and after installation (certification, workmanship warranty and mediation routes).

Installation process

REST UK's process consists of nine steps: a free postcode check to confirm the property's solar potential; a roof assessment by an MCS-certified surveyor analysing structure, orientation, shading, cable routes and electrical setup; CAD system design with calculation of predicted annual generation; a bespoke proposal with specifications and projected performance; finance arranged according to the available options; confirmation of the installation date; MCS-certified installation with safety checks; commissioning and connection to the monitoring platform; and handover of documentation, warranties and ongoing support. The company states that most projects go from first survey to a switched-on system in around 14 days on average.

Referral programme

REST UK offers a referral programme through which a customer can receive £250 when someone they introduce contracts an installation.
