Solar panel prices in Warrington, by system size

Prices by system size

DESNZ solar PV cost data 2025/26: North West means (some non-domestic installs included) and UK medians, including VAT where it applied. Output: PVGIS 5.3 for central Warrington. Checked 3 November 2026.

Read the two price columns as a range rather than a target. The mean is pulled up by complicated or high-specification jobs; the median is the price half of installs came in under. A straightforward job on a two-storey Warrington semi will often sit near or below the median; a tall Victorian house with a slate roof may sit above the mean.

Batteries are not included in these figures. They are priced separately and add considerably to the total; see adding a battery.

Comparing a quote with the averages like for like

The North West figures rest on a large sample: 14,142 certified jobs up to 4 kW and 7,673 between 4 and 10 kW in 2025/26. To compare your own price with them fairly, three adjustments matter.

• Divide by the panels, not the inverter. DESNZ works out cost per kW from the total capacity of the panels. It notes that costs worked out this way are typically 6 to 12% lower than the same jobs measured per kW of declared net capacity. So multiply the number of panels by their wattage and divide the price by that.
• Take the battery out first. Battery storage is left out of the averages, so a quote that includes one needs the battery's share removed before the sum means anything.
• Leave out extended warranties too. The averages exclude them. If a quote bundles a longer cover at extra cost, compare the price without it, then judge the warranty on its own terms.

An illustration with made-up numbers: a quote of £6,800 for 10 panels of 400 W on a 3.6 kW inverter. Divided by the 4 kW of panels, that is £1,700 per kW, below the North West mean of £1,800. Divided wrongly by the inverter's 3.6 kW, it would look like £1,889 and seem dearer than average when it is not.

Try it yourself

If you already have a quote, the quote checker does the comparison for you: it takes the price and size, works out the price per kW, and sets it against the right North West average and against what PVGIS says your roof should make.

What moves a Warrington quote up or down

Usually up

• Scaffolding on a tall or awkward house. Three-storey Victorian and Edwardian houses need more scaffold, and so do houses where the scaffold has to cross a conservatory or a neighbour's drive.
• A roof that needs work. Slipped slates or tired battens should be fixed before panels go on. That work is charged at the standard VAT rate and should be shown separately.
• Premium equipment. Higher-efficiency panels, all-black panels or optimisers on every panel cost more; they can be worth it on a small or partly shaded roof.
• A battery-ready (hybrid) inverter. Usually a little dearer now, cheaper than adding a second inverter later.
• A bigger connection job. Systems needing G99 approval from the network operator take more paperwork and sometimes an export limit.

Usually down

• A simple gable roof on a two-storey house, which describes a great many of the homes built in Warrington's new town estates.
• A larger system. The cost per kW falls as the system grows, because the fixed costs are shared.
• Group buying. A Switch Together round, when one is running, gathers households so installers bid on price; see Switch Together.

VAT: 0% until 31 March 2027

Installing solar panels and batteries in a home in Great Britain is zero-rated for VAT until 31 March 2027. From 1 April 2027 the rate becomes 5%: on a £7,200 system that would add about £360. The relief depends on when the work is done, not when you sign, so if planning consent, a roof repair or a busy installer could push the work past March 2027, allow for it.

How Warrington households pay

• From savings, judging the system by what it saves and earns each year; see are panels worth it.
• The Warm Homes Loan Scheme, through approved lenders, which lets you spread the cost; some loans are interest-free and others carry reduced interest, and the work must be MCS certified. It is a loan, not a grant. This site does not arrange loans or name lenders; GOV.UK lists them.
• The Warm Homes: Local Grant, for lower-income households in homes rated EPC D to G, which can include solar panels fitted by the scheme's own installers; see grants and funding.
• Installer payment plans, where offered; ask for the total amount payable and compare it with paying outright.

What you get for the money

Electricity you use from your own panels saves the full unit price you would otherwise pay, while electricity you export earns an export tariff under the Smart Export Guarantee, typically around half as much per unit at the better rates. That is why the most useful question about price is not "how soon will it pay back" but "what is it worth to my household each year". The worth-it page works that out for a Warrington roof with every assumption stated.
