Common questions

When is the last frost date in the UK?

It varies hugely depending on where you live. In the far south-west of England, the last frost is typically in early April. In London and the south-east, it's mid-to-late April. The Midlands and north of England see their last frost in early May. Scotland ranges from mid-May to early June. Enter your postcode above for your specific date.

What can I plant before the last frost?

Hardy crops like broad beans, peas, onion sets, potatoes, lettuce, spinach, radishes, and kale can all go out before your last frost date. They can tolerate cold nights and light frosts. Tender crops like tomatoes, courgettes, runner beans, and peppers must wait until after the last frost.

How accurate are these frost dates?

Our estimates are calibrated against Met Office climate data and are typically accurate to within 5-7 days. However, frost dates are long-term averages — in any given year, the actual last frost could be earlier or later. Microclimates (sheltered gardens, frost pockets, urban heat islands) also affect your specific conditions. Always check the forecast before planting tender crops.

Is this tool free?

Yes, completely free. No signup, no subscription, no paywall. We built this because we were frustrated by how hard it is to get simple, personalised planting advice in the UK.
