The verdict in three sentences
For a humanitarian charity based in London, a credible website with online giving costs 15,000 to 30,000 GBP (about 17,500 to 35,000 EUR), delivered in 8 weeks and hosted for around 25 GBP a month. What reassures funders and donors is not the design but an up-to-date impact dashboard, downloadable annual reports and frictionless giving by card, Apple Pay and Direct Debit with Gift Aid captured at checkout. Built properly, the site covers its cost in year one and becomes the backbone of every funding application.
What funders check before they fund
A programme officer at a trust, foundation or institutional donor spends on average under 5 minutes on an applicant's website. They look for evidence, not slogans.
| Item checked | Funder expectation in 2026 | What the website must show |
|---|---|---|
| Legal status | Registered with the Charity Commission | Registered charity number in the footer of every page |
| Governance | Named trustees | Trustee board, roles, safeguarding and anti-fraud policies |
| Accounts | Filed annual report and accounts | Last 3 years of accounts and impact reports as PDF |
| Impact | Figures per programme | Dashboard: beneficiaries, water points, meals, classrooms |
| Field locations | Clear map | Interactive map by country and region |
| Fundraising standards | Registered with the Fundraising Regulator | Badge, complaints procedure, privacy notice |
| Languages | English plus field languages | EN, FR and one field language for partner communities |
A charity that ticks these seven boxes clears the first screening of a grant round more easily, which is worth far more than the website itself.
Detailed budget for the website and donation module
| Item | 2026 range | Comment |
|---|---|---|
| Trilingual website (12 to 18 pages) | 9,000 to 17,000 GBP | Design, CMS, built-in translation workflow |
| Donation module (one-off and monthly) | 3,000 to 6,000 GBP | Card, Apple Pay, Google Pay, Direct Debit, automatic receipts |
| Gift Aid declaration and export | 1,000 to 2,000 GBP | HMRC-ready claim file, declaration stored per donor |
| Impact dashboard | 2,000 to 5,000 GBP | Indicators updated by staff, charts |
| Card processing (charity pricing) | about 1.2 to 1.5% plus 20p | Discounted rates for registered charities |
| Direct Debit processing | about 1% plus 20p | Best channel for regular giving |
| Hosting and backups | 25 GBP/month | Fast server, UK or EU data location |
| Maintenance and updates | 200 to 350 GBP/month | Security, new reports, small changes |
Total project: 15,000 to 30,000 GBP, depending on the number of programmes and the depth of the dashboard. The 8-week plan: scoping and content gathering (weeks 1 and 2), design (week 3), development and payments (weeks 4 to 6), translation, live donation tests and launch (weeks 7 and 8).
Three technical choices that change everything
The first is speed: a large share of visitors arrive from social media on mobile, so a page should weigh under 1 MB. The second is compliance: UK GDPR and PECR consent for email marketing, plus a Gift Aid declaration worded exactly as HMRC requires. The third is autonomy: staff must be able to publish a report or update an indicator without a developer, in 10 minutes.
Mini case study
Emma, head of fundraising at a London water and sanitation charity, currently relies on a third-party giving page. With the new website and a supporter campaign, she targets in year one:
- 600 one-off donors at 45 GBP on average: 27,000 GBP
- 150 monthly donors at 12 GBP over 12 months: 21,600 GBP
- Total raised: 48,600 GBP, plus Gift Aid on 60% eligible gifts at 25%: 7,290 GBP
- Processing fees at about 1.5%: 730 GBP
- Website cost: 22,000 GBP, hosting and maintenance: 3,360 GBP a year
- Net in year one: about 29,800 GBP, and the monthly donors keep giving in year two.

On top of this comes the effect on funders: a single 50,000 GBP trust grant won thanks to a better-documented application changes the scale of the calculation.
FAQ
Should we use our own donation form or a giving platform?
Your own form keeps donor data and the relationship with you, at about 1.2 to 1.5% card fees. Platforms are quick to launch but often limit data access and branding.
How does Gift Aid work on the website?
The donor ticks a declaration at checkout, the site stores it and exports an HMRC-ready file. On 10,000 GBP of eligible gifts, the charity reclaims 2,500 GBP.
Do we need a field-language version?
For pages aimed at partner communities and volunteers, yes. Translating key pages typically costs 600 to 1,200 GBP per language.
Who updates the impact dashboard?
Your team, from a simple interface. A 2-hour training session is enough, and a quarterly update of 6 to 10 key indicators is the standard funders expect.
What does the website cost each month after launch?
Around 25 GBP for hosting and 200 to 350 GBP for maintenance, so roughly 225 to 375 GBP a month in total.
