Estimate early budgets
Use CostIntel calculators to create planning-level budget ranges for common home improvement projects, from interior updates to wider renovation decisions.
CostIntel helps UK homeowners create early planning estimates for home improvement projects, compare renovation scenarios and prepare more confidently before requesting quotes.
The site is built for people who want a clearer starting point before speaking with builders, installers, designers or other qualified professionals. Our calculators and guides help organise project assumptions, typical cost factors and budget allowances in one place.
CostIntel is designed to make early renovation planning easier to understand. The tools help turn rough project ideas into clearer cost assumptions before you start comparing quotes.
Use CostIntel calculators to create planning-level budget ranges for common home improvement projects, from interior updates to wider renovation decisions.
Test different renovation options, finish levels, allowances and planning assumptions before deciding which route may be worth exploring further.
Use the results to ask clearer questions, spot missing quote details and understand which parts of a project may affect the final price.
Many homeowners begin a project with only a rough idea of what they want to do. Before quotes are requested, it can be hard to judge whether a budget is realistic, which assumptions matter, or where costs might change.
CostIntel exists to make that early stage easier. The site gives users a structured way to think about home improvement costs without pretending that an online estimate can replace a proper site visit, specification or professional quote.
The aim is simple: help homeowners make better-prepared decisions before they commit time, money or expectations to a project.
A useful estimate should show the assumptions behind it. CostIntel focuses on ranges, selected inputs, project allowances and visible limitations, rather than presenting a single number as a fixed answer.
CostIntel focuses on planning estimates for UK home improvement and renovation projects. Each tool is built around selected project assumptions rather than live contractor pricing.
| Planning area | How CostIntel can help |
|---|---|
| Project planning | Compare renovation budgets, value uplift scenarios, build-vs-buy decisions and project allowances. |
| Interior costs | Estimate planning ranges for kitchens, bathrooms, flooring, carpets, plastering and painting. |
| Cost guides | Understand the practical factors behind extensions, roofing, driveways and landscaping projects. |
| Budget preparation | Organise likely allowances, contingency and quote questions before contacting professionals. |
The figures and outputs on CostIntel are planning estimates only. Actual costs may differ after a site inspection, detailed specification, professional assessment or formal quote.
CostIntel is built to support early planning. It does not replace qualified professional advice, detailed surveys, contractor quotes or regulated services.
We do not inspect properties, price jobs on behalf of trades, provide fixed project quotes or confirm what a builder or installer will charge.
Our planning tools do not provide formal property valuations, mortgage advice, investment advice, tax advice, legal advice or guaranteed value uplift.
A calculator result is shaped by user inputs, selected assumptions and broad planning ranges. It should not be treated as a guaranteed final cost.
Structural work, electrics, plumbing, roofing, drainage, planning issues and building regulations should be checked with qualified professionals where needed.
CostIntel is most useful before the quote stage. You can use the tools to test whether a project feels broadly affordable, compare possible routes and prepare a more detailed brief for contractors.
Start by choosing the closest calculator or guide, entering realistic assumptions and reviewing the result as an estimated range rather than a final price. If the project depends on access, structural condition, hidden defects or specialist work, allow for extra uncertainty.
Once you have a clearer planning estimate, the next step is to request quotes from suitable professionals and compare what each quote includes, excludes and assumes.
A planning estimate is only useful when the assumptions are visible. CostIntel is built around clear language, traceable inputs and honest limitations.
We aim to explain how project type, size, finish level, contingency and other selected assumptions can affect an estimated range.
Home improvement pricing can vary widely. Ranges are used to reflect planning uncertainty rather than presenting one figure as certain.
CostIntel points users towards quote checks, professional advice and related pages where a project needs more detailed review.
You can read more about our assumptions on the Methodology page and the Pricing Data page.
These sections can help you move from early research to more structured planning.
