Open Gardens Insurance UK: Do You Need Cover to Open Your Garden for Charity?

Do You Need Insurance to Open Your Garden?

There is no law that requires a private householder to buy public liability insurance before inviting visitors into their garden. But opening a garden to the public, even for one Sunday afternoon in aid of the village church or a hospice, changes your legal position. Once people arrive in numbers, pay an entry fee and wander across your lawn, paths and steps, you owe them a duty of care. If someone trips on a loose paving stone, slips on a wet path or is hurt by a falling branch, a claim can be made against you personally.

That is why the sensible answer is "yes, in practice". The real question is not whether you need cover, but whose policy provides it and whether it actually responds to an open garden day.

Why Your Home Insurance May Not Be Enough

Many householders assume the public liability section of their buildings and contents policy will cover visitors. Sometimes it does, but often only for ordinary social visitors, not for a ticketed charity event. Some insurers treat an open garden as a "business or public activity" and exclude it, while others will accept it if you tell them in advance and may add terms. One organiser of a local open gardens weekend reported her household insurer confirming it would not cover anything arising from the open gardens, although the policy continued to apply to unrelated incidents.

The practical steps are simple. Tell your home insurer a few weeks before the opening, in writing, and describe what will happen: number of visitors, entry fee, teas, plant sales, parking, and any ponds, pools or play equipment on site. Ask for their reply in writing. Restricted cover with clear conditions is far better than discovering a gap after an accident.

If You Open Through the National Garden Scheme

Gardens opened under the National Garden Scheme (NGS) benefit from a public liability policy held by the scheme itself, covering garden owners, county volunteers and the NGS. Its published insurance guidance explains that cover responds to claims of personal injury or property damage arising from an opening, provided the opening benefits the NGS and the scheme is found legally liable. It extends to matters such as visitor injury, illness from food or drink where negligence is proven, parking on your property or a designated area, and theft of admission money for a period after the opening where reasonable care was taken.

The exclusions matter just as much. NGS guidance lists swimming pools, boats, aircraft (including remote-controlled devices), bouncy castles and firework displays as outside the cover, and says the list is not exhaustive. Theft of or damage to the owner's own property, unattended honesty boxes and tins, and gardens open on a commercial basis or on non-NGS days are also excluded. Owners are expected to insure their own property and display the NGS notice, label and fence off hazards, and obtain proof of public liability insurance from third-party operators such as tea providers or entertainers. If something goes wrong, they must report it to the county organiser promptly and avoid admitting liability.

The same principles apply to Scotland's Gardens Scheme, the Red Cross open gardens campaign and similar schemes: each has its own insurance arrangements and conditions, so read the scheme's own guidance rather than assuming.

Opening for a Local Charity or Village Event

Most open gardens in the UK are not NGS openings. They are village open gardens weekends, church or hospice fundraisers, and street trails where a dozen neighbours open at once. Here the picture is less tidy, and the organising group should answer three questions before tickets go on sale.

• Does the organiser hold a policy that covers the gardens? Some charity or parish policies cover only volunteers working on the day and exclude private premises. If a local society says "our insurance covers it", ask for the certificate and check that it names garden visitors and private gardens.
• Is each garden owner a named insured, or merely a volunteer? The policy should respond to claims made against the individual householder.
• What is the limit of indemnity? £5 million is the usual starting point for public liability; £10 million is increasingly requested.

If the organiser has no suitable cover, a one-off event policy for the whole trail is often cheaper than every householder buying their own. Organisers of one group reported quotes in the region of £150 to £190 to insure around 30 gardens with fewer than 100 visitors each, though quotes vary by insurer and by what you declare. Treat any figure as a guide only and ask for a quote based on your own plans.

The Hazards That Cause Claims

Gardens contain more hazards than most owners notice because they have walked the same paths for years. A fresh pair of eyes helps: ask a friend to walk the route as a first-time visitor and note anything they stumble over.

Surfaces, steps and slopes

Uneven paving, loose gravel, slippery steps and steep banks are the classic causes of falls. Mark steps clearly, fix or cone off trip hazards, consider a handrail, and put mats on wet or mossy surfaces. Visitors are often older, so assume less steady footing.

Water

Ponds, pools and water features raise the stakes. Insurers ask about them directly, and NGS cover excludes swimming pools. Fence or net ponds, supervise them if children are expected, and declare them when you notify insurers.

Trees, tools and play equipment

Check for dead or low-hanging branches before the day. Put tools, sharp implements and chemicals away and locked. Trampolines and climbing frames should be taken out of use or clearly signed as unavailable, since insurers may take a dim view of children playing on equipment you have not declared.

Keeping the house private

Decide which areas are public and which are not. Keep the house off limits unless you are providing toilets, lock doors and windows, hide valuables and secure sheds. If visitors use a house toilet, someone should accompany them, as the NGS guidance recognises.

Teas, Plant Stalls and Parking

Refreshments raise the takings and the risk. Volunteers baking scones for a charity tea do not need a separate products policy as a matter of law, but a claim for food poisoning or an allergic reaction can follow any food service, so check that your public liability includes products liability. Keep ingredient labels, display allergen information clearly and follow basic hygiene. Anyone selling food regularly should be registered with the local authority, and a one-off charity tea is typically treated more lightly, but check with your environmental health team if in doubt.

If outside sellers take pitches, such as a plant nursery or a cake maker, ask for their public liability certificate in advance. If a stallholder is uninsured and a customer is injured, you as the host may be the easier target for a claim. Lycetts, a specialist rural insurer, makes the same point in its guidance for garden openers: require stallholders to carry their own products liability.

Parking deserves more thought than it usually gets. Visitors arriving in a field or on a verge are exposed to uneven ground, reversing vehicles and mud. Appoint marshals, keep pedestrians and cars separate, and have a wet-weather plan. NGS cover applies to parking on your property or a designated area, but only for NGS openings, so non-NGS organisers must confirm their own policy extends to it.

The Cover at a Glance

Cover	What it protects	Open garden relevance
Public liability	Injury to visitors or damage to their property	Essential; check the home policy and organiser cover
Products liability	Illness from food or goods sold	Needed if you serve teas or sell produce
Home insurance (buildings and contents)	Your own property and garden items	Notify insurer; theft by visitors may be limited
Money cover	Theft of admission money and takings	Useful when cash is held on site
Event cancellation or weather	Irrecoverable costs if the day is called off	Rarely worthwhile unless significant costs are committed

Weather, Cancellation and Cash

A garden opening is the most weather-dependent event in the community calendar. For a low-cost, owner-run opening there is usually little to insure against beyond lost takings, which cancellation cover will not replace. Where a group has paid for marquees, hired toilets or printed tickets in advance, adverse weather cover may be worth pricing. Our adverse weather insurance guide explains what is and is not covered. For cash, count takings at the end of the day, bank them promptly and avoid leaving money in an unattended honesty box, which schemes such as the NGS specifically exclude from theft cover.

If Someone Is Hurt

Offer help and call emergency services if needed, but do not admit liability or make promises about paying compensation, as that can prejudice your insurance. Record what happened while it is fresh: take photographs, note the time and conditions, and collect names and addresses of witnesses. Report it to your insurer and the organising group as soon as possible, ideally the same day. Our guide on how to make an event insurance claim sets out the steps.

A Practical Checklist

1. Tell your home insurer in writing a few weeks before the opening and get their reply on file.
2. Ask the organising group or scheme for the policy wording and confirm it covers private gardens and your name.
3. Check the limit of indemnity (£5 million minimum, £10 million if required).
4. Declare ponds, pools, play equipment, refreshments, plant sales and parking.
5. Walk the garden for trip, fall, water and tree hazards and fix or mark them.
6. Collect public liability certificates from stallholders and entertainers.
7. Keep the house and valuables secure and designate public and private areas.
8. Have a simple incident record, first aid kit and a named person in charge on the day.

The Bottom Line

Opening a garden for charity is a generous thing to do, and the insurance is rarely expensive, but it is also easy to get wrong because everyone assumes someone else's policy has it covered. Do not rely on your household policy until your insurer has said so in writing. If you are opening under a scheme such as the NGS, read the scheme's insurance guidance carefully, especially the exclusions. If you are part of a local trail, ask the organiser to prove the cover before anyone sells a ticket. A few emails now are far cheaper than a claim made against your home.
