Frequently Asked Questions
Please contact us at enquiries@aisolar.co.uk if you cannot find an answer to your question.
A standard 4kW domestic solar PV system in the UK typically costs £5,500 to £7,500 fully installed in 2026, including panels, inverter, mounting, electrical work, and DNO notification. VAT is 0% on residential installations until at least March 2027. Prices have fallen roughly 30% since 2021 and are still trending down.
Adding battery storage typically increases the upfront cost by £3,000 to £5,000.
The length of time it takes to install solar panels depends on the size of the system and the complexity of the installation. Typically, residential installations take 3-5 days while commercial installations can take several weeks.
In most cases, no. All four technologies are covered by permitted development rights in England, and the rules have been progressively relaxed through 2024 and 2025 to make installation easier. You'll only need planning permission if your property is a listed building, in a conservation area, AONB, National Park or World Heritage Site, or your installation exceeds the size limits currently permitted without specific planning permission.
The Smart Export Guarantee is a UK government scheme that requires large electricity suppliers — those with more than 150,000 customers — to pay you for surplus renewable electricity you export to the National Grid.
SEG rates in 2026 range from around 1p/kWh at the worst end to 25p/kWh at the best, depending on supplier and tariff type. For a typical 4kW solar system without a battery — generating roughly 3,400 kWh per year and exporting around 1,500–2,000 kWh — you could earn anywhere from £60 to £400 per year.
In most cases, yes — but with caveats. Modern panels are far more capable than they were a decade ago, and many roofs once dismissed as unsuitable are now viable. North-facing roofs typically produce 50–60% of what an equivalent south-facing roof would generate, and partial shading can usually be managed with the right inverter and panel placement. The honest answer for any specific property is "it depends" — which is why we always do a free site survey before quoting.
Shading reduces output more than poor orientation does — and shading even a single panel can affect a whole string of panels if the wrong inverter is used. The good news is modern technology handles partial shading much better than older systems:
- String inverters (the cheapest option): a shaded panel pulls down output across its whole string. Avoid if your roof has significant shading.
- Power optimisers (Tigo, SolarEdge): each panel reports independently, so shading on one panel doesn't drag the others down. Adds around £400–£800 to a typical install.
- Microinverters (Enphase): each panel has its own inverter on the roof. Best for complex roofs with multiple orientations or shading patterns. Adds around £800–£1,500 to a typical install.
For any roof with chimney shadows, neighbouring trees, dormers, or buildings nearby, optimisers or microinverters are usually well worth the extra cost.
The Boiler Upgrade Scheme is a UK government grant programme run by Ofgem on behalf of the Department for Energy Security and Net Zero (DESNZ). It pays a one-off contribution towards the cost of installing a low-carbon heating system — a heat pump, heat battery, or in some cases a biomass boiler — to replace an existing fossil fuel or non-heat-pump electric heating system. The scheme launched in May 2022 and has been extended to 2030.
The grant is paid upfront — as MCS installers, we apply on your behalf and deduct the grant from your invoice before you pay. You never have to wait for reimbursement.
The current grant amount is £7,500 for an air source heat pump (air-to-water).
Temporary uplift for oil and LPG households: From July 2026 to March 2027, the air source heat pump grant is expected to increase from £7,500 to £9,000 for homes and small businesses in England and Wales that currently rely on heating oil or LPG. This is a limited-time uplift — worth acting on if you're in that group.
The core eligibility rules are straightforward:
- You own your property (homeowner or small business owner)
- The property is in England or Wales
- Your current heating is a fossil fuel boiler (gas, oil, LPG) or an electric heating system without a heat pump (storage heaters, panel heaters, direct electric)
- The new system has a maximum capacity of 45kW (single) or 300kW (shared ground loop)
- The installation is carried out by an MCS-certified installer
You contact us first — not the manufacturer. As your installer, we handle the entire warranty claim process on your behalf: diagnosing the fault, liaising with the manufacturer, sourcing the replacement, and reinstalling it. You shouldn't have to deal with paperwork or international phone calls. We aim to have any in-warranty replacement installed within 2–4 weeks of fault diagnosis, and any out-of-warranty repair quoted within 5 working days.
Every quote we provide includes panels, inverter, mounting hardware, all electrical work, DNO notification, MCS certification, scaffolding, and commissioning — with no hidden extras. We provide a written system specification with expected annual generation in kWh and full warranty details so you can compare us against any other installer like-for-like.
