In most cases, no.

Most domestic solar installations fall under "Permitted Development" in the UK.
However, if you live in a listed building or a conservation area, different rules may apply.

Don't worry, our team will assess this during your initial survey and guide you through any necessary steps.

The efficiency of solar panels has steadily increased over the decades from being able to produce 130kWh in 1980 to 460kWh in 2026.

They continue to produce power even on overcast days. In fact, rain is helpful, as it provides a natural "rinse" to keep your panels clean and performing at their peak efficiency.

Solar panels have no moving parts, making them extremely low maintenance.

Depending on local environment including dust pollution. Manufacture's recommend an inspection once per year.

Standard solar systems are designed to switch off during a power cut for the safety of engineers.

However, GGRS can design your system with a specific battery backup system that allows you to ‘island’ your home, keeping your essential appliances running even when the rest of the street goes dark.

Adding a 5kWh battery typically increases the total cost of a standard solar-only system by 50% to 80% but it can double your annual electricity use*

*Cost and savings estimates are site-specific. Figures are an estimate produced using industry standard modelling software (OpenSolar) and are subject to specific survey and design conditions.

Generate your own power and lock in lower costs. The average system provides an annual output of 4,015kWh. That’s the equivalent of providing the energy for 4,000+ full cycles of a washing machine or 1,600+ hours of cooking time with an electric oven.

The average UK household can see a yearly energy bill reduction. By generating this power yourself, your locking in these lower costs for the 25 – 30 year lifespan of your panels, protecting your household from future grid price spikes.

Make a measurable impact. Switching to solar allows the average home to cut its carbon emissions by 1 to 1.5 tonnes of CO2 every year - the equivalent of planting 75 trees*. Furthermore, solar offsets its own manufacturing footprint in less than 12 months*

Providing a clean, silent, and renewable energy source that offsets its own manufacturing footprint in less than 12 months.

*Carbon saving estimates are based on site-specific production data calculated using OpenSolar, which has been independently validated for accuracy by National Renewable Energy Laboratory (NREL) and (PV Evolution Labs) PVEL .

*Heatable Solar Advice (2024) and NREL PV FAQs, confirming that modern high-efficiency PV modules typically achieve a carbon/energy payback in 4–12 months.

Take advantage of government support. With 0% VAT on installations until 2027 and the Smart Export Guarantee (SEG) that may allow households to receive payments eligible surplus electricity exported to the grid. Financed benefits will vary depending on system size, energy usage, tariff and supplier terms.

Take charge of your energy usage. Solar panels paired with battery storage can help reduce reliance on grid electricity and may help protect against rising energy costs.

Depending on system design, property characteristics, and energy usage, some households may significantly increase their level of energy self-sufficiency.

Levels may increase by storing daytime solar generation for use in the evening. Outcomes vary depending on size, energy usage, and seasonal conditions.
