You must agree to the Terms and Conditions

Terms and Conditions

By organising your own fundraising event in aid of Macmillan, you are responsible for taking adequate steps to make sure that the event poses no risk to others, therefore, you will need to carry out the appropriate risk assessments and consider whether or not you need insurance. Check that any buildings or equipment that you hire are covered. Insurance is often included in the hire fee but not always. You may need to consider arranging public liability cover for some events, which will protect you against claims made by third parties for injury or property damage as a result of negligence. In most cases, for public and/or hazardous events, you may need public liability cover in place. For private events this may not be necessary. Please seek advice if you are unsure. For more information you can contact the Fundraising Support Centre on 0300 1000 200 or by email on fundraising@macmillan.org.uk
