Buyer’s Checklist

How to evaluate nonprofits & charities web developers in Cardiff

5 things to check before hiring

These are the questions and checks that separate nonprofits & charities specialists from general web agencies who will list your sector on their homepage after you sign.

Charity registration number and regulator name displayed prominently: donors in Cardiff verify registration before donating, display it in the footer and on the 'About' or 'Donate' page minimum

Impact metrics displayed alongside donation CTAs: naming what a specific donation amount funds, such as a set number of meals or a month of a service, connects donation to outcome, this single copy change consistently increases average donation value

Multiple donation options: one-off and recurring monthly giving, with recurring framed as the default, most Cardiff charity websites default to one-off when recurring generates 3–4x more annual revenue per donor

Volunteer sign-up flow: volunteer recruitment through the website is often as valuable as fundraising for Cardiff charities, a clear, low-friction sign-up form with role descriptions converts better than a generic 'get involved' CTA

Story-led content architecture: impact reports, beneficiary stories (anonymised where appropriate), and campaign updates build the emotional connection that turns one-time donors into recurring supporters of your Cardiff cause

Platforms & Tech Stack

Which platform for nonprofits & charities in Cardiff?

WordPress with Charitable or GiveWP

The most common platform for Cardiff charity websites. Charitable and GiveWP provide donation management, recurring giving, Gift Aid processing (UK), and donor reporting without the percentage-per-transaction fees of generic payment processors.

Webflow with Donorbox integration

For Cardiff charities that prioritise visual storytelling alongside donation functionality. Donorbox's embeddable widget handles the transaction layer while Webflow manages the brand experience.

Squarespace for small charities

A manageable option for small Cardiff charities without technical resource. Squarespace's built-in donation blocks are basic but functional, and the CMS is manageable by non-technical charity staff.

Salesforce Nonprofit Success Pack (NPSP)

For larger Cardiff charities with complex donor management requirements. A web developer who can integrate the public-facing fundraising site with Salesforce NPSP provides a unified view of donor relationships across online and offline giving.

Questions & Answers

Nonprofits & Charities web development in Cardiff - common questions

Pre-brief questions that nonprofits & charities businesses in Cardiff ask before commissioning a web project.

How much does a charity website cost in Cardiff?+

A small Cardiff charity or community group site costs £600–£2,200, many developers offer discounted rates for registered charities. An established charity with full donation and volunteer management pays £2,200–£7,000. Large charities budget £7,000–£25,000 and international NGOs invest £20,000–£80,000+.

What is the most important design decision on a charity website in Cardiff?+

Making the impact of a donation concrete and immediate. '£25 = X meals for Y children in Cardiff' is more powerful than 'please donate to support our work'. The web developer's job is to present these impact equivalents prominently on the donation page, ideally as selectable donation amounts where each value is pre-labelled with its specific impact. This single design decision consistently increases average donation values.

Should Cardiff charities have recurring giving on their website?+

Yes, always, and it should be the default option. Monthly giving generates 3–4x more annual revenue per donor than one-off giving, and donor retention rates for regular givers are 80-90% compared to 30-40% for one-off donors. The best Cardiff charity websites make monthly giving the pre-selected option and frame the one-off alternative as the secondary choice.

Do charity websites in Cardiff need to be accessible (WCAG compliant)?+

Yes, and this is increasingly enforced by regulators and grant-maker requirements. WCAG 2.1 AA compliance is the minimum standard for public sector and charity websites in United Kingdom. Practically, this means: sufficient colour contrast, keyboard navigability, screen reader compatibility, and alt text on all images. A Cardiff web developer who builds charity websites should be able to provide a basic accessibility audit as part of the project.

What should a Cardiff business look for in a contract before hiring a web developer?+

A properly scoped web development contract for a Cardiff business should include: a fixed-price quote (not hourly with uncapped scope), a detailed scope of work document, a timeline with specific milestones and delivery dates, ownership of all source code and assets on completion, a warranty period of at least 30 days post-launch for bug fixing, and clear terms for revision rounds. Avoid any contract that includes a retainer obligation as a condition of handover, this is a red flag in the Cardiff web development market.

How long does a Cardiff web project typically take from brief to launch?+

A standard business website for a Cardiff company takes 2–4 weeks from brief to launch (assuming content is provided on time). A custom web application with integrations typically takes 6–12 weeks. E-commerce sites with product catalogue setup take 3–8 weeks. The most common cause of delays in Cardiff web projects is late content delivery from the client, agree a content deadline before the project starts and the timeline holds reliably.

Should a Cardiff business hire a local web developer or work with a remote agency?+

For most Cardiff businesses, a remote web development agency delivers equivalent or better results than a local studio, at 20–40% lower cost. The key factors are: quality of portfolio (verifiable through live URLs, not PDF screenshots), communication responsiveness (same-day replies are the baseline for professional agencies), and clear ownership transfer on handover. Physical location has not been a meaningful differentiator for web development quality since 2018. Tecklogist serves clients across United Kingdom and 40+ countries entirely remotely.

How can a Cardiff business verify a web developer's experience before signing?+

The three most reliable verification methods for Cardiff businesses evaluating web developers are: 1) Live portfolio links, the agency should provide direct URLs to live sites they built (not PDF mockups), which you can test for speed, mobile quality, and design; 2) Client references, ask for contact details for two recent clients in a similar sector; 3) Technical audit, ask the developer to explain how they would handle a specific technical challenge for your project. A developer who cannot answer this clearly has not built what they claim. Tecklogist provides live portfolio URLs, verified client references, and a free technical scoping call for every Cardiff project enquiry.
