Website project costs in the UK: what to budget for

Start with a decision, not a page count

Write down the customer you want to help, the action they need to take and the problem with the current experience. A ten-page site with one repeated layout may involve less design work than a smaller site with a catalogue, account area and several enquiry routes. Page count is one input, not a complete specification.

Choose a first release that does a useful job. Put essential services, evidence and the enquiry journey ahead of features nobody has agreed to maintain. If the existing website can support that work, ask for an improvement option alongside a rebuild. Our website design and development service explains how we scope both routes.

Separate the build from the running costs

Ask each supplier to label costs as one-off, recurring, usage-based or optional. Confirm whether quoted amounts include any applicable taxes; do not assume two totals use the same basis.

There is no market price table here: a useful figure needs an evidenced scope. BrandFlame's pricing approach explains how a project quote separates agreed work, third-party charges and optional care. Ask suppliers to state the assumptions behind any estimate and when it can be confirmed.

Identify the decisions that change the quote

Content readiness often changes the work. “We will supply the text” could mean approved copy for each page, old documents needing substantial editing, or notes that need to become a first draft. Give the supplier a representative sample and agree which interpretation they are pricing.

Integrations need the same precision. A link to an existing booking page, an embedded form and a two-way connection to a CRM are different requirements. Provide product names, account plans and the actions required. Compatibility should be checked before development is committed, rather than inferred from a logo on a supplier website.

For an online shop, list product types, variants, delivery rules, payment requirements and who owns stock information. Include the condition of the catalogue data and any records that need to move. Our eCommerce service covers discovery, checkout, migration and order handling as separate parts of the brief.

Copy this budget worksheet

Use these prompts in your own document. Leave unknown figures open until a supplier confirms them; an empty amount is more useful than an invented allowance.

• Purpose: the visitor, their main task and the business outcome you will assess.
• First release: essential page types, content and features; separately list later ideas.
• Content responsibility: who supplies, edits and approves each item, with readiness dates.
• Existing systems: product, plan, account owner and required connection for each tool.
• Build quote: agreed scope, amount, tax treatment and payment stages tied to deliverables.
• Recurring costs: each subscription or support item, billing frequency, owner and renewal terms.
• Variable costs: the usage measure, allowance and what happens above it.
• Contingency decisions: unresolved work, who estimates it and who authorises changes.
• Acceptance: the evidence required before agreeing that the work is complete.

For a fair comparison, give every shortlisted supplier the same version. Ask them to mark an item as included, excluded, optional or awaiting investigation. Do not compare a quote including copywriting and migration with a design-only quote as if they covered the same work.

Test the worksheet with a fictional brief

Imagine a consultancy replacing an outdated site. It needs clear service pages, team profiles and an enquiry form. One proposal includes content editing and a launch checklist. Another expects finished copy and treats migration as additional work. Neither is automatically better: the buyer needs to decide who can supply the missing work and compare the resulting complete scope.

If a client portal is only a future possibility, price its discovery separately. Avoid making the website launch depend on an undefined software project. This example illustrates a buying decision, not a BrandFlame client or a quoted package.

Agree how changes and ongoing care work

Before work begins, ask what counts as a correction to an agreed requirement and what counts as a new request. Record how a change affects price, dependencies and the schedule. Confirm who can approve it on each side.

At handover, identify who can edit content, who owns the relevant accounts and how to report a problem. Care arrangements should state supported tasks and response arrangements explicitly. A hosting subscription alone does not explain who will update content or investigate a failed enquiry.

Your next step is a short scope outline, not a finished technical specification. If you are comparing suppliers as well as budgets, use our agency-selection questions. If the project replaces an existing site, use the redesign checklist to identify migration work before requesting a quote.
