Buy outright, spread the cost, or pay nothing upfront — plus the Welsh grants worth knowing about.
Residential installs carry 0% VAT until 31 March 2027 — a saving worth locking in.
Spread the cost, or let a funder cover it entirely with Solar-as-a-Service for businesses.
From Green Home Loans to Newport's SME decarbonisation grant — we'll help you find and time it.
It depends on your roof, orientation, energy usage, and whether you add battery storage. A typical well-sited domestic system can cut electricity bills substantially, and any surplus you export can earn you money through the Smart Export Guarantee. We'll give you a realistic, property-specific estimate at survey stage — not a generic sales figure.
Most domestic rooftop solar installations fall under permitted development, so no planning permission is needed. Exceptions include listed buildings, conservation areas, and some flat-roof or ground-mounted systems. We'll flag any planning considerations at survey.
Batteries let you store the solar energy you generate during the day and use it in the evening, rather than exporting it cheaply and buying electricity back at a higher rate. They can also charge on cheap overnight tariffs. For most households with solar, a battery significantly increases self-consumption and savings.
A heat pump extracts heat from the outside air — even in cold weather — and uses it to heat your home and hot water. For every unit of electricity it uses, it typically delivers three or more units of heat, making it far more efficient than a gas boiler or direct electric heating.
Contact us and we'll arrange a survey. You'll receive a written, itemised quote with a system design and realistic performance estimates. We comply with the RECC Consumer Code, so our quotes are transparent, with no pressure selling and clear cancellation rights.
