Example Solar Installations
Solar designs we've done in Cosby
These are real 3D roof designs from Spectrum quotes in Cosby, for homes and businesses. Every solar quote we send includes one for your own roof, showing where each panel goes.

Commercial Solar Cosby
Cosby's neighbourhood plan counts more than 50 registered businesses in the village, including the firms on Cambridge Road, and the 15th-century Tithe Barn is now a dining venue. Just to the north, the industrial estate on the old Whittle site at Whetstone adds modern commercial and storage buildings.
Workshops, farm buildings and commercial roofs can all take solar. For a firm that runs through the day, most of the output replaces bought-in power, and payback is typically around 4 to 8 years.
We handle the design, the grid application and maintenance afterwards, and businesses can claim capital allowances on the system cost (your accountant can confirm the relief). Read our guide to solar for businesses or see our case studies.
Residential Solar Cosby: Landlords and Developers
Cosby grew in stages: villas around 1900, council housing on Park Road and Lady Leys between the wars, the Settlement in 1938 for out-of-work families from Wales and the North East, and large private estates in the 1960s. Blaby's Local Plan names it one of the district's Medium Central Villages, and solar helps landlords raise an EPC rating and developers meet Part L.
We run portfolio jobs as one project, with phased installs and Part P certification. Read about solar for property portfolios or new-build developments.
Domestic Solar Panels Cosby: Homeowners
A Cosby home with solar imports less electricity, and adding a battery carries the midday output through to the evening. We cover every part of the village, from the older streets along the brook to the 1960s estates, and the villages around it.
If your home is in the conservation area or is one of the 13 listed buildings in the parish, we check the planning position before we design, including the neighbourhood plan's policy on the conservation area.
Domestic solar and battery installs are zero-rated for VAT, currently due to run until 31 March 2027 (the rate is set by when the job is installed and invoiced), and you are paid for exported power through the Smart Export Guarantee. We can add battery storage, EV charging and, if you want it, Home Assistant with Predbat as an optional extra.
What Matters for Solar in Cosby
Planning and Conservation
Blaby District Council decides planning applications in Cosby, and the Cosby Neighbourhood Plan, made after a referendum on 24th November 2022, is part of the development plan. Most home solar is permitted development, but the original heart of the village is a conservation area, covered by the plan's Policy CNDP1, and the parish has 13 listed buildings, including St Michael and All Angels church, the war memorial and the K6 telephone box on The Nook.
Grid Connection
Cosby is on National Grid Electricity Distribution's East Midlands network. Most home systems need only a G98 notification and larger ones G99 approval, and we check the MPAN on your bill before applying.
Homes and Roofs
Cosby's older buildings date from its framework knitting and shoemaking days, when Henry Nixon and Co. and Ward Bros. ran shoe factories in the village and Burleys had a hosiery factory here. The Great Central Railway once ran along the east side of the village, open from 1899 until 1969.

Kit, Warranties and Guarantees
We fit tier-one panels (30-year performance warranty on the models we use most), Solis hybrid inverters supplied with a 10-year warranty, and Fogstar batteries on most homes or Pylontech on larger commercial systems, and we can usually supply another make if you prefer; see our solar technology.
Every installation carries our 5-year workmanship guarantee and a QANW insurance-backed guarantee on top of the manufacturers' warranties, and Spectrum is insured through QBE UK Limited (£10M employers' liability, £5M public and products liability, £1M professional indemnity).
Accredited and Insured
How It Works
We start with a satellite view of your roof and your electricity use, then send an all-inclusive design and quote (subject to site survey), normally within 48 hours. A site survey confirms the details, we handle the grid paperwork, and most homes are installed in 1 to 2 days, around 4 to 6 weeks from first enquiry; our installation guide explains each step.
What Our Customers Say
★★★★★
"Brilliant company to deal with. From the initial chat about my requirements to installation, I can't fault one thing. I found Solar somewhat a minefield with some people trying to bamboozle me with information but Spectrum helped explain it in simple terms. The installation was faultless and they even called me 2 days later just to check everything was running OK. 10/10 team. Would definitely recommend."

Frequently Asked Questions
Does Cosby have a conservation area?
Yes. The original heart of the village is a conservation area, and the Cosby Neighbourhood Plan has a policy on development in and around it. Roof solar is often still permitted development there, but listed buildings need consent, and any application goes to Blaby District Council.
Is Cosby on the NGED network?
Yes, National Grid Electricity Distribution's East Midlands network covers Cosby. We read your MPAN before we apply, in case a newer home is on an independent network.
Which villages around Cosby do you cover?
Littlethorpe, Narborough, Whetstone, Countesthorpe, Blaby, Broughton Astley, Croft, Huncote and Enderby, as well as all of Cosby.
Are solar panels worth it in Cosby?
For most homes and businesses, yes. Payback is typically around 8 to 10 years for homes and 4 to 8 years for businesses, depending on your tariff and how much of the power you use yourself.
How much do solar panels cost in Cosby?
We quote one all-inclusive price for your roof and your usage, covering scaffolding, labour, the grid application and certification, and the quote shows the projected savings and payback before you commit. Some grid connections also carry a network operator fee, typically around £153 plus VAT.
Do you offer finance?
No, we are not a credit broker. We give you a clear written quote to take to your own lender if you want to borrow, and we do take card payments if you want to use a credit card offer.
