In many cases fixing solar panels to your roof is likely to be considered 'permitted development' under planning law with no need to apply for planning permission.

There are, however, important exceptions and provisos which must be observed.

If you are a leaseholder, you may need to get permission from your landlord, freeholder or management company.

If you wish to install a solar panel on your roof building regulations will normally apply.

The ability of the existing roof to carry the load (weight) of the panel will need to be checked and proven. Some strengthening work may be needed.

Building regulations also apply to other aspects of the work such as electrical installation.

It is advisable to contact an installer who can provide the necessary advice, preferably one who belongs to either the Microgeneration Certification Scheme or the relevant Competent Person Scheme.

Solar panels use energy from the sun to produce water heating (in the case of solar thermal) and electricity (solar photovoltaic).
