Birmingham's Solar Gap: High Bills, Low Solar

As the energy price cap rises again on 1 July 2026, new analysis of government data shows Birmingham has one of the lowest rates of solar adoption in the country, despite being one of the English cities hit hardest by fuel poverty.

Birmingham sits in an uncomfortable position. According to the latest government figures, 82,964 of its households (19.3%) are in fuel poverty. That's the second-highest rate of any city in England after Stoke-on-Trent, and nearly double the England average of 11.4%. Yet only around 2.9% of homes in the city have solar panels installed, one of the few permanent ways a household can cut its energy bills.

With the Ofgem price cap pushing the electricity unit rate up by around 13% from 1 July, that gap is about to cost Birmingham households more than ever.

Key findings

• 82,964 Birmingham households (19.3%) are in fuel poverty. That's second only to Stoke-on-Trent among English cities, and nearly double the England average of 11.4%.

• Only around 2.9% of Birmingham homes have solar, covering roughly 12,366 domestic installations across 429,715 households.

• From July, a typical home with solar could save around £537 a year, based on a standard 3.5kW system and the new price cap rate.

• Birmingham's low uptake comes during a national solar boom. UK rooftop installations in 2025 reached their highest level since 2011.

Why this matters now

The 1 July price cap rise lands hardest on the households least able to absorb it. Birmingham's fuel poverty rate means nearly one in five homes already struggles to afford adequate energy. For these households, every increase in the unit rate widens the gap between what they pay and what they can afford.

Solar doesn't solve fuel poverty on its own. The upfront cost puts it out of reach for the households that need bill relief most, which is exactly why awareness, access and funding routes matter. But the city-wide picture is the more striking story: across Birmingham as a whole, including homeowners who can readily afford it, adoption has stalled at under 3%. The city that feels the energy squeeze hardest is the one turning least to the technology that eases it.

What a Birmingham home actually saves

The saving comes from two places: the electricity you generate and use yourself (avoiding the grid unit rate), and the surplus you export back to the grid through the Smart Export Guarantee.

Using a standard 3.5kW system generating roughly 2,975 kWh a year, with around half used in the home and half exported:

Over the lifetime of a system, that adds up to thousands of pounds kept in the household rather than paid to an energy supplier, and it grows as grid prices do.

The "it doesn't work here" myth

A lot of Birmingham homeowners cite the weather as the reason they haven't gone solar. It doesn't hold up. Solar panels generate from daylight, not direct sunshine, and homes across the UK, including in cloudier regions than the West Midlands, are already generating effectively. The barrier in Birmingham isn't sunlight. It's awareness of what's now possible and access to installers homeowners can trust.

Methodology

All figures are drawn from primary government sources and are reproducible. Assumptions are stated in full.

Fuel poverty: Sub-Regional Fuel Poverty Statistics 2025 (2023 data), Table 2. Birmingham: 82,964 households in fuel poverty, 19.31% of all households (Low Income Low Energy Efficiency measure). England average: 11.4%. This is the most recent sub-regional release; figures reflect 2023 data.

Solar adoption: Solar Photovoltaics Deployment, April 2026, domestic installations by parliamentary constituency. Birmingham total (12,366) is the sum of the nine Birmingham-named constituencies. Adoption rate calculated against the DESNZ household base for Birmingham (429,715), giving 2.88%, expressed as "around 2.9%."

Saving estimate: Illustrative, for a standard 3.5kW system generating ~2,975 kWh/year (85% performance ratio), with 50% self-consumption. Self-consumed electricity valued at the Ofgem price cap electricity unit rate effective 1 July 2026 (26.11p/kWh); exported electricity valued at a typical Smart Export Guarantee rate of ~10p/kWh. Individual savings vary with system size, roof orientation, household usage and tariff.

Price cap: Ofgem, announced 27 May 2026, effective 1 July to 30 September 2026.

The bottom line

Birmingham doesn't have a sunlight problem or a suitability problem. It has an awareness and access problem. As bills climb again this July, the homes that close the gap will be the ones that keep more of their money, and the city as a whole has a long way to go.

If you're a Birmingham homeowner weighing up solar, the first step is understanding what your roof could realistically generate and save. Solar Panels Birmingham will connect you with a vetted local installer for a free, no-obligation quote.
