The UK has a reputation for grey skies and drizzle and while that is not entirely undeserved, the reality of UK sunlight hours is more encouraging than most people think. The country gets a surprisingly wide range of sunshine depending on where you live, and understanding that variation can help you make smarter decisions about your home - from where you site an extension to whether a rooflight is worth the investment.
In this guide, we look at real UK sunlight hours data by region, the sunniest and least sunny places in the country, how the seasons affect daylight, and what it all means for bringing more natural light into your home.
How Many Sunshine Hours Does the UK Get Overall?
According to long-term Met Office data covering 1991 to 2020, the UK as a whole averages around 1,403 hours of sunshine per year. That works out at roughly 3.8 to 4 hours of sunshine per day across the year - though this varies enormously between summer and winter.
The UK's sunniest months are May, June, and July. May in particular regularly tops the charts, with some years recording over 200 hours of sunshine in that month alone across England. By contrast, December and January are the darkest months, with many areas seeing fewer than 2 hours of sunshine per day on average.
It is also worth noting a broader trend: the UK has been getting gradually sunnier over time. 2025 was confirmed by the Met Office as the UK's sunniest year on record, with an average of 1,622 hours of sunshine recorded across the country -comfortably beating the previous record of 1,587 hours set in 2003. England had its sunniest year ever, and Scotland recorded its second brightest.

The Sunniest Places in the UK
If you live in - or are moving to the South East, you are in the best position when it comes to natural light. Chichester in West Sussex is consistently ranked as the UK's sunniest city, with Brighton close behind at an average of 5 hours of sunshine per day across the year. That is almost double what you would get in Inverness, Scotland's least sunny city, which averages fewer than 3 hours per day.
The South West also performs well. Plymouth, Southampton, Exeter, and Truro all feature in the top tier for UK sunshine hours, and the South West's milder climate means the sunny season effectively starts earlier and ends later than in the North.
Interestingly, Dundee is the standout performer in Scotland - the only Scottish city to consistently exceed 4 hours of daily sunshine. Aberdeen is not far behind at just under 4 hours per day. Glasgow and Inverness sit at the bottom of the national rankings.
The Least Sunny Regions
Scotland and Northern Ireland receive the fewest sunshine hours in the UK overall, though there is variation within both countries. The west coasts of Scotland and Wales tend to be cloudier than the east, largely because prevailing Atlantic weather systems bring more cloud and rain from the west.
In Northern Ireland, Belfast averages around 3 hours 46 minutes of sunshine per day - slightly less than Manchester, which sits at around 3 hours 44 minutes, making it one of the least sunny major English cities.
The North West of England and Northern England generally see 200 to 400 fewer sunshine hours per year than the South East - a meaningful gap when you are thinking about how your home uses natural light.
How Seasons Affect UK Sunlight Hours
The contrast between summer and winter in the UK is stark. In summer, long days mean that even cloudy regions get a reasonable amount of daylight. In winter, particularly in the North, daylight hours can drop to as few as 7 hours per day and much of that time is often overcast.
This is one of the key reasons rooflights and skylights have become so popular in UK homes. In the darker months, the angle of sunlight changes - coming in lower from the south - which means overhead glazing can actually capture more of it than a standard vertical window. A well-positioned rooflight will bring light into the centre of a room at precisely the time of year when you need it most.
Conclusion:
Understanding UK sunshine hours by region has practical implications for how you design and light your living spaces. Whether you are in a sun-rich area like Brighton or somewhere cloudier like Manchester, one thing is consistent: maximising natural light from above makes a genuine difference to how a home feels, particularly in winter.
That is where rooflights come in. At Skylights Roof Lanterns, we supply BBA-certified rooflights that are designed to perform in real UK weather - including the grey, overcast skies that make up a large part of the year in many regions. Our flat rooflights and roof lanterns are built with high-performance glazing that maximises the light you get even on duller days, and our pitched roof skylights are ideal for loft conversions and sloped roof extensions across all UK regions.
If you are planning an extension, loft conversion, or simply looking to brighten a dark room, explore the full range at skylights-rooflanterns.co.uk and make the most of every hour of light your region has to offer.
