2-minute estimate

Start with a clear view of your solar potential.

Choose home or business. We will show what the available information can support and be clear about what still needs checking.

Choose your route

What kind of site is this?

The questions and calculation are different for a home and a high-energy-use business.

IF YOU PREFER YOU CAN PICK A HOME SIZE FROM THE LIST AND YOUR PROPOSAL WILL BE INDICATIVE BASED ON AVERAGE ROOF SIZES AND RETROFIT ON RAIL SYSTEM WITH 480 WATT PV PANELS

This quicker route skips the detailed questions. Choose the closest average home size to see the corresponding indicative package.

Average home size Every preset is an early guide only and remains subject to survey, roof condition, electrical checks and final design.

The estimated costs reflect current average installation costs across the UK and are a realistic guide, but remain subject to a site survey for final design and quotation.

Or tailor the estimate

Answer the questions below when you want the calculator to reflect the actual building, roof and energy information available.

Building and roof

The building stage suggests a mounting route; you can confirm another option or choose “not sure”. Listed and conservation status changes what permission is needed before anything can be fitted.

Building stage

Listed or conservation status Outbuildings within the grounds of a listed building normally count as listed too.

Provisional mounting preference

Roof covering

Main roof direction

Approximate roof pitch

Approximate daytime shading

Approx. clear roof width (metres, if known) Leave blank if unknown. The planning estimate applies provisional edge and fitting margins.

Approx. clear pitch or rafter length (metres, if known) Both clear dimensions are needed for a panel-count indication.

Energy use

Use annual kWh or an average monthly bill when known. For a new build or extension without energy history, choose an indicative home size instead.

Annual electricity usage (kWh, if known)

Or average monthly electricity bill (£, if known)

Day unit rate (p/kWh)

Postcode area

Electricity supply

Hybrid inverter

Battery storage

Number of battery modulesIgnored when “No battery” is selected.

Gateway / backup management

EV charger

Home energy managementAdvanced option integrates EV charging, heat pump, hot water and whole-house backup.

Building width for scaffolding (metres)Example: 10 m wide.

Building height for scaffolding (metres)Example: 5 m high.

Scaffold elevationsChoose two elevations when panels are planned on opposing east/west or south/north roof faces. Indicative rate: £25 per m².

Business energy profile

These inputs reveal whether the site deserves a commercial energy review. They do not create a technical design.

Type of site

Listed or conservation status Converted barns, farm buildings and high-street premises are frequently listed or protected.

Annual electricity usage (kWh)

Approx. total roof area (m², if known) Leave blank if unknown. The screening model provisionally treats 65% as usable.

What the indicative package includes
Modern all-black 440 W solar panels, a compatible high-efficiency inverter, roof-specific mounting, system monitoring, standard installation, commissioning and handover. If selected, the battery illustration adds an approximately 8.3 kWh home battery with a 5 kW hybrid inverter for solar storage and off-peak tariff shifting. Exact manufacturers and warranties will be confirmed in the formal proposal.

What you will get

A transparent planning indication based on the details you enter.
A clear separation between home and commercial use cases.
The provisional on-roof or in-roof route for a home project.
The consent route when the building is listed or in a conservation area.
A sensible next step when important information is still missing.
A local Cotswold company with retained fitters, roofers and electricians—not unknown subcontractors.
Outstanding customer and technical support that national companies simply cannot offer.
Real testimonials from customers you can speak to. Don’t take our word for it.

What you will not get

A structural assessment, final layout, DNO approval or binding quote.
A binding quotation before product, roof and electrical checks.
A household battery assumption applied to an industrial site.
We don’t do cheap. We leave that to the “smash it in” teams. No—we deliver quality, support and integrity.

Paying for it

A minimum 25% deposit is required, with full payment due on practical completion of the installation. This excludes DNO final-approval certification lead times, which are outside our control.

RETURN ON INVESTMENT (ROI)

Using our entire installation portfolio to date, the average return on investment across our customer portfolio is just 7.4 years. The average annual saving on customers’ electricity bills is £1,474, representing an approximate annual saving of 67%.
