County Londonderry, BT47–BT48
The north west sits slightly lower on annual irradiance than the east coast, so honest modelling matters more here. We use location-specific figures rather than a Northern Ireland average, which typically moves a Derry estimate by 3–5%.
Steep terraced streets in the city side can complicate scaffolding access; we survey access constraints up front so the price does not move later.
Whatever the property, the design process is the same: we model your roof from satellite imagery and location-specific irradiance data before we visit, then survey the structure, shading, consumer unit and earthing arrangement so the quote we give you is fixed.
The short answer
Do you cover Derry~Londonderry?
We size the array from your electricity use and design it around your roof's pitch, orientation and shading. We also handle the NIE Networks paperwork.
A battery keeps the solar you don't use during the day for the evening. On a night-rate tariff it also works without panels, charging cheaply overnight.
A smart charger on your drive or in your garage, at a fixed price after we survey your supply and cable route.
Send us your address and a recent bill. We model your roof from satellite imagery and location-specific irradiance data, and tell you straight away whether it is worth a visit.
An engineer checks roof structure and covering, shading through the day, your consumer unit, earthing arrangement and cable routes. This is what makes a fixed price possible.
A single page with the system, a generation estimate for your specific roof, the price with nothing excluded, and a realistic payback based on your actual consumption.
We finalise the electrical design and submit the NIE Networks G98 notification or G99 application, plus building control notification. You do not fill in a form.
Scaffolding up, system in, tested and commissioned. Most domestic solar installations take one to two days; batteries and EV chargers, half a day to a day.
We set up your monitoring app, walk you through the system, and issue your electrical certificates and warranties. We submit the NIE Networks notification on your behalf.
Yes. Derry~Londonderry and the surrounding BT47–BT48 postcodes are part of our standard coverage. Your survey, installation and aftercare are managed from our base in Larne, and all electrical work is carried out by NICEIC-approved electricians.
The same as anywhere else in Northern Ireland: around £5,000–£6,500 for a 4 kWp system and £7,000–£9,000 for 6 kWp, fully installed with 0% VAT. Local factors that can move the price are scaffolding access, roof covering and whether your consumer unit needs upgrading.
Yes. A 7.4 kW smart chargepoint typically costs £800–£1,200 installed in Derry~Londonderry, including the dedicated circuit, protection and certification. We survey the supply and cable route first so the price is fixed before we start.
We do. Systems up to 3.68 kW per phase are notified under G98 after commissioning; anything larger needs G99 approval before connection. We submit both, plus building control notification.
Send us your postcode and a recent bill. We'll model your roof and tell you whether solar is worth it there. If it is, we survey and give you a fixed written price.
