Picking a donation website for your UK charity comes down to four numbers: platform fee, card processing rate, tip-prompt default, and Gift Aid processing charge.

Choosing a donation website in 2026 is less about features and more about fee maths. Most comparison articles list ten platforms, wave at the costs, and leave charities to discover later that 'free' still meant 1.9% plus 20p per transaction, a 5% Gift Aid processing charge, and a 17% tip prompt nudging donors to top up on the way out.
This guide does the maths out loud. We have rated nine donation platforms on the only things that decide cost-per-pound raised: the effective fee on a £100 gift (with Gift Aid), who the platform is actually built for, what is included without an upcharge, and how long it takes to get to your first donation.
Zeffy is on the list because 100,000+ charities globally have raised over £2 billion on it with £0 in platform, transaction, or card processing fees, Gift Aid handling included. Every other row has a real cost, and you deserve to see it before you choose.
Transparency: We have not received payment for placement from any platform listed here. Zeffy is the publisher. The methodology, fees, and pros and cons below are applied identically to Zeffy and to every other platform on the list. All fees have been verified against live UK compare pages as of June 2026.
In this article:
| Donation website | Platform fee | Processing fee | Key strength | Key limitation |
|---|---|---|---|---|
| Zeffy | £0 | £0 (Zeffy absorbs processing) | Full feature set (forms, ticketing, P2P, auctions, raffles, donor management) included free | Registered nonprofits in US/Canada only; no individual campaigns |
| GoFundMe | £0 (optional donor tip) | 2.2% + £0.30 registered charities; 2.9% + £0.30 personal | Massive audience reach; GoFundMe Pro (formerly Classy) adds nonprofit-focused tools | Pro pricing is custom and demo-gated; recurring on regular GoFundMe carries 5% |
| Donorbox | 2.95% (Standard tier) | 2.2% + £0.30 (Stripe) | QuickDonate one-click recurring; Salesforce + Mailchimp integrations | Stacked platform + processing, roughly £5K/yr on £100K raised |
| Give Lively | £0 | ~2.2% + £0.30 (Stripe, passed to nonprofit) | No platform fee; text-to-give and P2P included | Membership gated; manual approval can take ~10 days |
| Fundly | 4.9% | 2.9% + £0.30 | Fast campaign setup, mobile-optimized | ~8% effective fee; limited donor management |
| Double the Donation | Subscription (starts ~£300/yr) | Not a payment processor | Leading matching-gift database (360MatchPro) | Bolts onto a primary platform, not a standalone donation tool |
| DonorsChoose | Closed marketplace (no platform fee charged to teachers) | ~1.5% optional support fee | Donors fund specific classroom projects; materials shipped directly | US public-school teachers only, not for general nonprofits |
| RallyUp | 0% on tip-funded free tier; 2.9%–6.9% on paid tiers | 2.9% + £0.30 | Auction, raffle, and sweepstakes mechanics built in | Dropping the platform fee requires a paid tier |
| DonorPerfect | Subscription (starts ~£99/mo) | Payment processing sold separately | Deep CRM, segmentation, major-donor prospecting | Demo-gated sales; forms are secondary to the database |
The full breakdown for each platform follows. If you want the short version: Zeffy is the only row where the platform fee, the processing fee, and the Gift Aid processing fee are all £0. You can see how Zeffy's free donation website works before reading further.

Before comparing platforms, UK charities need to understand four separate levers that together determine what actually reaches the cause.
1. Headline platform fee. This is the percentage the platform takes from each donation. JustGiving, Enthuse, Wonderful.org, and Crowdfunder UK all headline at 0%. Zeffy is also 0%. Localgiving charges a membership fee rather than a per-donation percentage.
2. Card processing. Most platforms pass on Stripe's UK card rate of 1.5% plus 20p per transaction, or something close to it. GoCardless Direct Debit costs 1% plus 20p, capped at £2 per payment, which makes it the most cost-effective channel for regular gifts. A platform that says '0% platform fee' but passes through card processing is not fee-free.
3. Donor tip prompt. JustGiving and Enthuse both default to an opt-out tip prompt of roughly 17%. The donor sees the prompt after entering their donation amount. If they do not actively remove it, the platform takes that percentage on top of the donation. Money Saving Expert has covered this extensively and UK Trustpilot reviews for JustGiving cite it frequently. A 17% tip on a £50 donation adds £8.50 to the donor's total, none of which reaches the charity.
4. Gift Aid processing fee. This is the charge that most platforms never mention loudly. Gift Aid allows a UK-registered charity to reclaim 25p from HMRC for every £1 donated by a UK taxpayer. A £100 donation becomes £125 to the charity. Several platforms, including JustGiving and Enthuse, charge a 5% fee on the reclaimed Gift Aid value. On that £100 donation: £25 Gift Aid reclaim, minus 5% (£1.25) to the platform. Zeffy charges nothing on the Gift Aid uplift. The full £125 reaches the charity.
The Code of Fundraising Practice (current version effective 1 November 2025, with new Section 9 covering online platforms) requires fundraising platforms to be transparent about their fee structures. When evaluating any platform, ask for the combined effective rate across all four levers on your average gift size.
Zeffy is the only platform on this list where UK registered charities keep 100% of donations, including the Gift Aid uplift. No platform fees, no transaction fees, no card processing fees, no Gift Aid processing fees. 100,000+ charities worldwide have raised over £2 billion on Zeffy. The full feature set is included; there is no paid tier above it.
100% free for registered charities. The charity never pays a platform, transaction, card processing, or Gift Aid processing fee. Ever.
JustGiving is the dominant UK donation platform and has been since 2001. Donor brand recognition is genuine: most UK supporters have used it or seen it. The headline platform fee is 0%. The honest story is more complicated.
0% platform fee. Card processing 1.9% plus 20p. Gift Aid processing fee 5% of the reclaimed Gift Aid value. Opt-out tip prompt defaults to roughly 17%. For verified pricing, see the Zeffy vs JustGiving comparison.
Enthuse is the official online fundraising partner for London Marathon Events (TCS London Marathon) and the Great Run series under a contract that runs to 2034. If your charity has places in those events, Enthuse is not optional. Outside those flagship events, the value proposition is more competitive.
0% platform fee. Card processing 1.9% plus 30p. Gift Aid processing fee 5% of the reclaimed Gift Aid value. Events: 3.5% plus 75p per ticket. Optional subscription £29.99 plus VAT per month. For verified pricing, see the Zeffy vs Enthuse comparison.
CAF Donate is built and operated by the Charities Aid Foundation, itself a registered charity with decades of sector infrastructure behind it. More than 8,000 small-to-medium UK charities use it. Trustees and finance teams recognise the CAF name and that name-recognition removes friction in internal sign-off processes.
Wonderful.org uses Open Banking (account-to-account transfers) to deliver 0% platform fee, 0% Gift Aid processing fee, and 0% transaction fee on Pay by Bank donations. Money Saving Expert has praised the model, and technically it is the most cost-effective card-free option available.
Crowdfunder UK is the UK's largest crowdfunding platform. Its 0% platform fee for charities is the headline; the real reason to choose it over JustGiving is match funding. Crowdfunder has partnerships with the National Lottery Community Fund, local authorities, and other funders who add matched contributions to qualifying campaigns. That match funding can double or triple a campaign's total.
GivenGain launched in the UK in 2022 and is growing its footprint through partnerships with organisations including Swimathon, British Heart Foundation, and Dame Kelly Holmes Trust. It is a subscription-free peer-to-peer alternative to JustGiving with automated Gift Aid built in and no Gift Aid processing fee.
GoFundMe UK is the dominant platform for personal and emergency crowdfunding in the UK. Its brand recognition with individual donors is strong. For registered charities, the picture is more nuanced.
Localgiving is a membership-model platform built specifically for small local UK charities and community groups. It bundles donation pages with training, sector support, and access to match-funding and grant campaigns from local and national funders. The membership fee is the main contrast with free alternatives.
A note on CRM tools. If what you actually need is a supporter database rather than a donation website, the UK answer is Beacon or Donorfy, both UK-built fundraising CRMs designed for the sector. They pair with a donation platform like Zeffy or JustGiving rather than replacing one.
Seven things actually decide whether a donation website is right for your charity. They are worth more than feature checklists.
Only platforms that absorb processing actually deliver £100 to the mission. Most 'free' platforms still pass Stripe UK card rates (1.5% plus 20p) to you, and several stack a platform percentage or Gift Aid processing fee on top. Do the maths on a £100 gift, not on a £10,000 campaign. Small donor receipts are where stacked fees hurt most. You can run the numbers in the fee calculator against your average gift size.
GoFundMe is built for individuals and personal crowdfunding moments. Localgiving is built for the smallest local community groups. Crowdfunder UK is built for time-bound project campaigns. Many comparison guides flatten these into a single ranked list. Match the platform to your context first, then compare fees within that context.
Regular giving, event ticketing, peer-to-peer, supporter records, and Gift Aid capture. These are either included or sold as add-ons. A platform that includes them all at £0 looks very different from one that gates them behind a paid tier or a per-module charge.
This is the UK-specific criterion that separates a professional charity fundraising platform from a generic payment tool. A platform that does not automate Gift Aid declaration capture and HMRC claim submission is leaving 25% of eligible donations on the table. Ask specifically: does the platform submit Gift Aid claims to HMRC on your behalf via Charities Online, or does it only capture declarations that you then have to submit yourself? And does it charge a Gift Aid processing fee on the reclaimed value?
If you have to export payment data, match it against a spreadsheet, and manually issue year-end acknowledgement letters, you are using a payment processor with a form on top, not a fundraising platform. Automated donation acknowledgements and a built-in supporter record are the floor for a proper fundraising tool.
Manual eligibility review, contract signatures, and minimum commitments are real switching costs that do not appear in fee tables. If you need to fundraise this week, setup timelines matter as much as fee percentages.
Any platform serving UK donors must comply with the Code of Fundraising Practice (updated 1 November 2025, with new Section 9 on online platforms) and UK GDPR and PECR for donor data. Ask where donor data is stored, whether the platform has a UK-facing Data Protection Officer, and whether it is registered with the ICO.
Map your situation to one of these patterns:
Stacking tools is the hidden cost most UK charities overlook. A £15 fete ticket on Ticket Tailor, an autumn appeal on JustGiving, a Christmas raffle through a separate lottery tool, and a sponsored 5K on another peer-to-peer platform means four separate platforms, four separate fee structures, four separate supporter databases to reconcile, and Gift Aid declarations scattered across all of them. Zeffy consolidates that entire stack, free, with Gift Aid handled in one place.
It depends on the platform and which fees you count. JustGiving headlines at 0% platform fee but adds card processing of 1.9% plus 20p and a Gift Aid processing fee of 5% on the reclaimed Gift Aid value. Enthuse has the same structure. Wonderful.org takes 0% on Pay by Bank donations. Crowdfunder UK takes 0% platform fee for registered charities, with card processing on top. CAF Donate charges a staggered donation fee with no monthly subscription.
Zeffy is the only platform on this list where the platform fee, card processing fee, and Gift Aid processing fee are all £0. For a £100 donation with Gift Aid, Zeffy delivers the full £125 to the charity. Every other platform on this list retains some portion of either the donation or the Gift Aid uplift.
Most platforms take under an hour to set up a basic donation page. The steps are broadly:
1. Register your charity with Companies House (if a charitable company) and with the Charity Commission for England and Wales, OSCR (Scotland), or CCNI (Northern Ireland) depending on where you operate.
2. Apply for HMRC recognition separately from your charity registration. This gives you a Charities Reference Number and enables you to make Gift Aid claims via Charities Online. Your charity can be registered with the Charity Commission and still not be HMRC-recognised for Gift Aid purposes.
3. Sign up to your chosen platform. For Zeffy, the sign-up process is free and does not require a demo gate or eligibility review. For JustGiving, Enthuse, or CAF Donate, you will need to verify your registered charity number.
4. Connect your payment account. Zeffy handles Stripe under the hood at no cost to the charity.
5. Set up your donation form, add your charity's branding, and configure Gift Aid declaration capture. On Zeffy, donors can tick the Gift Aid declaration at checkout, so you can submit claims to HMRC without chasing separate paperwork.
6. Test the donor journey end to end before sharing the link.
Gift Aid declarations captured at checkout are the step most platforms handle differently. Ask your platform whether it submits claims to HMRC on your behalf or simply stores the declarations for you to submit manually.
JustGiving, Enthuse, CAF Donate, Wonderful.org, and GivenGain all capture Gift Aid declarations and support HMRC claim submission. Zeffy captures Gift Aid declarations at checkout and is the only platform on this list that does so without charging a Gift Aid processing fee on the reclaimed value.
Gift Aid allows a UK-registered charity to reclaim 25p from HMRC for every £1 donated by a UK taxpayer. That uplift is worth 25% of every eligible donation. A platform that takes 5% of the reclaimed Gift Aid is taking 5% of a free resource your charity earned. Zeffy takes nothing.
To claim Gift Aid, your charity must be HMRC-recognised (separate from Charity Commission registration). Donors must have paid at least as much UK Income Tax or Capital Gains Tax as the charity will reclaim on their donation.
Localgiving is built specifically for small local UK charities and community groups, including some that are not yet registered charities. It bundles donation pages with training, sector support, and access to match-funding opportunities from local funders.
CAF Donate is also used by very small charities and has no monthly subscription, so the entry cost is low.
Zeffy is free for registered charities regardless of income size. A charity raising £5,000 a year faces the same £0 platform fee as one raising £500,000.
If you are not yet a registered charity (a community group, CIC, or unincorporated association), you cannot claim Gift Aid and most charity-tier pricing is unavailable to you. Localgiving accepts some community groups. Wonderful.org's 0% Pay by Bank works if your donors can navigate the Open Banking authentication flow.
At a minimum: a branded donation form, regular giving capability, Gift Aid declaration capture, automated donation acknowledgements, and a basic supporter record. Beyond that, the features that matter most depend on your fundraising mix.
If you run events: integrated ticketing, so your donors are not switching between platforms when they book a fete ticket and then make a separate donation.
If you run raffles or prize draws: compatibility with the UK small-society-lottery framework under the Gambling Act 2005, which requires registration with your local council for draws with over £20,000 in ticket sales.
If you run peer-to-peer fundraising: individual fundraiser pages with Gift Aid capture so each sponsored runner's donations are Gift Aid-eligible.
Zeffy includes all of these at £0. Most other platforms gate event ticketing, auctions, raffles, or peer-to-peer behind a paid tier or a separate tool.
For most small registered UK charities (under £500,000 income), the question reduces to: do you need reach, match funding, or control?
Reach: JustGiving has the largest UK donor base and the strongest cold-donor recognition. The tip prompt and Gift Aid fee are the costs.
Match funding: Crowdfunder UK is the strongest option if your campaign qualifies for National Lottery or local-authority match funding.
Control and cost: Zeffy gives you full control of the donor journey, captures Gift Aid declarations, and takes nothing from any donation or from the Gift Aid uplift.
For most small charities with a regular programme of events, appeals, and community fundraising, the stacked-tool problem (separate platforms for ticketing, donation pages, raffles, and peer-to-peer) is the bigger issue than any single platform fee. Zeffy consolidates that stack at £0.
Yes. Many UK charities use JustGiving for London Marathon and Great Run sponsorship pages (because of the Enthuse exclusivity), Crowdfunder UK for a specific capital project, and a dedicated donation platform for their main website donate button. There is no rule against it.
The practical cost is fragmented supporter data. Gift Aid declarations, donation histories, and donor contact details end up in different systems, which makes year-end reporting and HMRC Gift Aid claims harder to reconcile. An all-in-one platform like Zeffy reduces that fragmentation at no additional cost.
