Use a reference, then price your own roof
Energy Saving Trust lists around £7,600 for a typical 4.5 kWp domestic solar installation, checked on 8 September 2026. This is a national reference, not a Ware average, a battery package or an offer from this website. The installed specification and access arrangements determine your quotation.
A simple roof with straightforward scaffolding is a different project from a converted building with shared access or several small roof slopes. Ask each installer to quote the same scope so a cheaper total does not conceal excluded work. Photographs help prepare an assessment, but cannot settle the structural and electrical design.
Separate equipment from the work needed to fit it
An itemised quote should identify panel model and quantity, array capacity in kWp, inverter, mounting, monitoring, scaffolding and electrical work. Check whether roof repairs, a consumer-unit upgrade, trenching to an outbuilding or removal of old equipment are included.
For Ware properties with shared roofs, clarify who can authorise the work and who pays for future access. If an installer needs a survey before fixing the price, ask which items remain provisional. Keep any planning, building-control and network responsibilities in the written scope.
Compare a battery as an additional purchase
Request a solar-only price and a separate installed battery price. Usable capacity in kWh describes stored energy; discharge power in kW limits how quickly it can be supplied. A large capacity figure does not tell you whether the battery can support several high-demand appliances at once.
Ask for estimated direct solar use, battery-supplied energy and exports separately. A unit cannot be both consumed by the household and sold to the grid. Include storage losses and the battery warranty assumptions when comparing the additional cost with the expected benefit.
Read the savings assumptions before the payback figure
A useful forecast names its annual generation estimate, shading assumptions, import and export rates, household use and any maintenance allowance. Compare a more cautious scenario too. Future tariffs, occupancy and equipment performance can change the result.
Ask how VAT has been applied to the actual installation. Qualifying domestic energy-saving work has specific rules; commercial premises and product-only purchases require their own treatment. Check payment stages, cancellation terms and the responsibility for warranties before accepting a quote.
Prepare your enquiry
Have a recent annual electricity-use figure, your full postcode and a description of the roof ready. Mention an EV, heat pump, planned roof repairs or interest in storage. Ware Solar introduces enquiries to partner installers; the installer confirms the survey, price and contract directly. A partner can arrange a booking within 24 hours of receiving the enquiry, with the appointment date agreed separately.
