Seven new planning applications hit Blackpool Council’s desk this week, flats, extensions, and solar panels among them. One number stands out: 7. In a town with 150,000 residents, that is barely a ripple. But the fact that solar panels even appear on a planning list should make every UK homeowner pause.
As reported by the Blackpool Gazette, the applications include solar installations alongside new flats. For most homeowners, that is the wrong headline. The real question is: why does rooftop solar need planning permission at all?
Permitted development, the rule most homeowners miss
In England, solar panels on a single-family home are classified as permitted development. That means no planning application is required, provided the panels do not project more than 200 mm from the roof surface and are not on a listed building or in a conservation area. The Blackpool applications likely involve flats, commercial buildings, or properties where the standard exemption does not apply. For the typical 3-bed semi in Manchester or Milton Keynes, the council never needs to see your solar plans.
The catch is that many homeowners do not know this. A 2023 survey by the Energy Saving Trust found 38% of respondents believed they needed planning permission for rooftop solar, a misconception that stalls installations by weeks or months. The real barrier is not the council. It is the distribution network operator (DNO).
What it costs a typical 3-bed semi
A 4 kW solar array, about 10 panels on a south-facing roof, costs typically £5,000 to £7,000 installed in the UK. The average household saves £300 to £500 a year on electricity bills, according to Ofgem data. Payback periods range from 10 to 15 years, depending on orientation, shading, and whether you add a battery. The EPC uplift is real: a D-rated home can jump to a C, adding value if you sell.
But the planning permission confusion is not the only thing slowing adoption. Grid connection delays are now the bigger problem. Some DNOs take 12 weeks or more to approve a simple connection. The government’s Smart Export Guarantee pays you for excess power at rates of 5p to 15p per kWh, but only if the grid can take it. In areas like Blackpool, where local infrastructure is ageing, that can be a harder hurdle than any planning officer.
Who qualifies, and who doesn’t
If you own a standard semi or terrace, not listed, not in a conservation area: you do not need planning permission. If you live in a flat, a listed building, or a designated area, or if your roof is flat and you plan to tilt panels, you may need an application. The Blackpool applications are a reminder that the rules differ by property type. Homeowners in conservation areas should check with their local planning authority before ordering panels.
For most, the bigger decision is whether to install now or wait for the next government scheme. The Boiler Upgrade Scheme currently offers £7,500 off a heat pump, but nothing directly for solar. The Smart Export Guarantee is not a grant, it is a payment for power you sell. No major new solar grant is expected before the next Spending Review in 2025.
What to do by when
Check your property’s listed status and conservation area designation on your local council’s website. If you are clear, get three quotes from MCS-certified installers, the industry standard. Apply for a grid connection as soon as you choose an installer; the DNO process can run in parallel with installation. If you are in a flat or listed building, speak to the council before you buy panels. The Blackpool applications show that solar is coming to more property types, but the paperwork still matters for some.
Frequently Asked Questions
For most single-family homes in England, solar panels are permitted development and do not require planning permission, provided they do not project more than 200 mm from the roof and the property is not listed or in a conservation area. Always check with your local council if you are unsure.
A typical 4 kW system costs between £5,000 and £7,000 installed. Savings on electricity bills average £300 to £500 per year, with payback periods of 10 to 15 years. EPC improvements can add 5-10 points, which helps when selling a home.
