Government Making Solar Panels Mandatory in Manchester?

Manchester doesn't sit still. The city that sparked the Industrial Revolution has spent the last decade reshaping its skyline, and from 2027, every new home rising across Greater Manchester will arrive with solar panels as standard. The government has made it law, and for Manchester's busy development pipeline, that change carries real weight.

Quick take: Solar panels are not yet mandatory on new homes under current building regulations. That changes on 24 March 2027, when the Future Homes Standard comes into force and makes on-site solar PV a mandatory requirement for most new dwellings across England, Manchester included. Existing homes are unaffected. Exemptions apply for shaded roofs, tall buildings, and certain design constraints. Here's everything you need to know.

What Is the Current Rule on Solar Panels for New Homes in the UK?

As of mid-2026, there's no government requirement for solar panels on new homes. Part L of the Building Regulations covers the energy and carbon performance standards that new buildings must meet, but it doesn't specify which technologies builders need to use to get there. Hitting the carbon targets is the requirement. How builders achieve that is left to them.

Across Manchester, plenty of new-build developers already fit solar PV as a voluntary measure. It helps meet carbon targets and appeals to buyers who want lower running costs from the outset. But official guidance has been consistent: solar panels are not currently mandatory under UK building regulations, and the government's approach has been technology-neutral throughout, leaving builders free to cut carbon without being pushed towards any particular solution.

That position is about to change.

What Is the Future Homes Standard?

The Future Homes Standard (FHS) is the government's new energy performance framework for homes built in England. It's the most far-reaching overhaul of building regulations in a generation, and it changes almost everything about how new homes are designed, heated, and powered.

Under the FHS, new homes must use low-carbon heating systems, primarily heat pumps rather than gas boilers, paired with very high levels of insulation and airtightness. The government's reasoning is straightforward: build homes right from the start and avoid expensive retrofits down the line. According to a Parliament statement from March 2026, new homes built under the FHS will emit on average at least 75% less carbon than homes built to 2013 standards.

The FHS was confirmed through 2026 building regulation changes. Every new home built under it will come with no fossil-fuel heating, strong insulation, and clean on-site energy from day one. For Manchester, a city with one of the most active new-build pipelines outside London, from regeneration schemes in Ancoats and Salford Quays to large residential developments in Wythenshawe and Stretford, this is a genuine step-change in how new housing gets built and delivered.

Are Solar Panels Becoming Mandatory on New Homes in Manchester?

Yes. Under the Future Homes Standard, the government is introducing a legal requirement for on-site renewable electricity on most new homes in England. In practice, that means solar PV as the default on the vast majority of new builds.

The amended Building Regulations include a functional requirement, subject to certain limits, that a renewable generation system must be installed when a new home is built. Approved Document L sets out that this is met when solar panels covering the equivalent of 40% of each dwelling's ground floor area are installed, though other compliant methods remain available.

For Manchester, the mandatory requirement applies across the city's entire new-build pipeline. Areas with active development, including north Manchester, east Manchester, south Manchester, and west Manchester, will all fall under the new mandatory rules once they come into force. Any new home whose building notice is submitted after spring 2027 must comply.

Solar moves from being a developer's option to a government-mandated standard.

Will Every New Build Home Need Solar Panels?

Most will, but not every single one. The government has deliberately built flexibility into the FHS, and certain properties can be exempt from the mandatory requirement.

The default rule is clear: new homes must include on-site renewable electricity. For the vast majority of new builds across Manchester, whether that's a new development near MediaCity, new flats in the city centre, or houses going up across Fallowfield and Eccles, solar panels will be fitted as standard.

Where a home's roof can't produce at least 720 kWh per year from solar PV, the mandatory requirement is waived. That threshold covers heavily shaded roofs and properties with very limited usable roof area, where panels simply wouldn't generate enough power to justify the installation.

There's also flexibility around the 40% coverage target. Where dormers, rooflights, or chimneys make full coverage impossible, a lower percentage is allowed. The government's rule is designed to be workable, not punitive. Builders won't be forced to strip back a roof design just to hit a number.

When Could the New Solar Panel Rules Come Into Force?

The government finalised the Future Homes Standard regulations on 24 March 2026. They come into force on 24 March 2027, with a transitional period running through to 24 March 2028.

Any dwelling whose building notice is submitted after spring 2027 must comply with the FHS. Builders and developers with schemes already in planning have the transitional period to work through those projects.

For buyers across Manchester, the practical takeaway is simple. Any new home completing from 2027 onwards should include solar panels as standard, assuming it meets the normal requirements. Developers with sites in Trafford Park, Chorlton, Didsbury, or anywhere else across Greater Manchester now have a fixed mandatory date to plan around.

Once the transitional period closes in March 2028, there's no further delay. All new homes built in England must meet the new standard.

Are There Any Exemptions to Mandatory Solar Panels on New Homes?

Yes. The government has built in several explicit exemptions and relaxations, known as Limits on Application, to make the mandatory solar requirement workable across a range of building types and site conditions.

Here's how the main exemptions work in practice:

Poor solar potential. If a home's roof can't produce at least 720 kWh per year from PV, the mandatory requirement doesn't apply. This covers shaded sites, properties near tall trees, and homes with very limited usable roof space.

Tall buildings. Any residential building with a storey 18 metres or more above ground is fully exempt. This mainly applies to taller apartment blocks rather than standard houses or lower-rise flats.

Alternative generation. Where a development has access to equivalent renewable electricity through a directly connected system, such as a shared energy network, the on-site panel requirement is lifted.

Architectural constraints. Where dormers, rooflights, or chimneys prevent 40% PV coverage, a lower percentage is permitted. Builders aren't forced to redesign a roof just to meet a coverage figure.

Alternative technologies. The legal requirement is for renewable electricity generation, not specifically solar panels. Other methods that produce the required output can qualify, though solar PV will remain the default on most new builds.

Final Thoughts on Solar Panels Being Mandatory on New Homes

This is one of the clearest housing policy changes the UK has seen in years. From 2027, the government makes solar panels mandatory on most new homes in England, and for Manchester that means clean energy built into new housing from day one.

For homebuyers across the city, whether you're moving into a new flat in Salford Quays or a house in Wythenshawe, the mandatory requirement means lower bills from the moment you move in. No arranging a separate installation. Solar arrives with the keys.

For developers and landlords planning new builds in areas like Ancoats, Trafford Park, or Stretford, designing solar into your schemes now puts you ahead of the mandatory date. Our vetted local installers are already working alongside new developments across Greater Manchester.

Existing homeowners, whether you're in a Victorian terrace in Chorlton or an Edwardian semi in Didsbury, aren't covered by the mandatory rules. But going solar now still makes strong financial sense. Solar Panels Manchester connects you with vetted local installers, and battery storage and solar maintenance services are available through our network.

Solar on new homes is now government policy. It's coming in 2027, and Manchester is well placed to benefit. Get in touch and Solar Panels Manchester will connect you with a chosen local installer to talk through your options.

Solar Panels Being Mandatory on New Homes FAQs

Are solar panels already required on new homes in the UK?

Not yet. Solar panels are not mandatory on new homes under current building regulations. The government has confirmed this position clearly, and the mandatory requirement only comes into force on 24 March 2027.

When will the new mandatory rules start?

The Future Homes Standard regulations were finalised in March 2026 and come into force on 24 March 2027. A transitional period runs to 24 March 2028 for projects already in planning.

Does this apply across the whole of the UK?

The Future Homes Standard applies to England only. Wales has its own clean energy standards for new homes, and Scotland is moving towards a zero emissions buildings approach. For new homes in Manchester and across the wider Greater Manchester area, the FHS is the relevant mandatory framework.

Will every new home have to have solar panels?

Almost all of them, yes. The mandatory requirement applies to most new dwellings, but properties where the roof can't generate at least 720 kWh per year from PV are exempt. Tall buildings with a storey at 18 metres or above are also fully exempt. For most new houses and lower-rise flats across Manchester, the requirement will apply.

What size installation is required?

The government's guidance sets a benchmark of panels covering roughly 40% of a dwelling's ground floor area. For a typical two or three-bedroom house, that works out at around 10 to 12 panels. A lower coverage percentage is allowed where design constraints apply, provided the system still delivers a reasonable energy output.

What about existing homes?

The mandatory rules apply only to new builds. Existing Manchester homeowners are not required to retrofit solar panels. That said, many choose to go solar now to cut their bills straight away.
