Street fundraising is likely to continue while it remains cost-effective. Figures state that charities gain as much as three quarters of their income from this method. However, some people find street fundraisers intimidating and may feel pressured into signing up to regular giving agreements. Signing up under pressure is against the fundraisers' guidelines and the majority of fundraisers who operate with good ethics will not sign someone up if they openly articulate their will not to sign up. In the UK some local councils have set up "cold caller exclusion zones" to prevent doorstep fundraisers.
