Solar panel cost
priced per panel
Panels, inverter, scaffolding and certification, itemised the way our quotations itemise them.
Brands we work with
A five panel system with a string inverter is £3,900 to £5,050 installed. Eleven panels with two batteries is £9,450 to £11,750, and a real quotation at that size came to £9,774.
Panels are £72 to £90 each and fitting them is £100 to £120 each, so the cost per panel falls as the array grows and the fixed costs spread.

Every figure on this site is an estimate based on published UK market ranges and our own installation experience. It is not a quotation. The price you are given after the free survey is the price you pay.
Every line, at our rates
Nobody in this trade publishes this. It is the only way to tell whether a quotation is fair.

What the price includes
Everything below is inside the figure. Nothing here is an extra we add later.
Scaffolding
In the figure. On a London terrace it is almost always needed, and leaving it out of the headline is how a quotation grows after you accept it.
MCS certification
Registration NIC-601634. It is what makes the export tariff claimable and what a mortgage valuer or a buyer's surveyor will ask for.
Flat roofs included
A London flat roof on tilted ballasted frames gets close to a south-facing pitch, and it needs no roof penetration at all. We fit more of these than pitched arrays.
Questions people actually ask
How much does one panel actually generate?
A 460 W panel on a reasonable London roof returns roughly 390 kWh a year, so 5.1 kWp of them is about 4,335 kWh.
What that saves depends entirely on how much of it you use rather than export, which is the argument for a battery.
Is a battery worth it?
A 5 kWh battery adds about £2,040 to £2,335 and lifts self-consumption from roughly half to around three quarters.
It is worth more if you have a heat pump or air conditioning, because both shift load into the evening when the panels have stopped. See battery costs.
Why is there VAT of zero?
Installing energy saving materials in residential property is zero rated until 31 March 2027, after which it is scheduled to return to 5 per cent unless it is extended.
We are VAT registered under GB471566866 and commercial work is treated differently.
The survey is free and the written price is fixed
We measure the property, tell you what it needs and put a price in writing that does not move.
