Pro Tool
Spec Your Renovation. Room by Room.
The UK property renovator's budgeting tool — build a detailed room-by-room specification with itemised costs, specification tiers, and a total project budget.
Unlock Renovation SpecDetailed Specification
Stop guessing renovation costs. Propty lets you build a detailed specification for every room — selecting individual items like flooring, plastering, electrics, and fixtures. Each item has a cost estimate based on UK averages, and you can adjust for your area.
Budget Control
Renovation projects are notorious for going over budget. Propty gives you a clear total from the start, with contingency built in. Compare your spec against the expected value uplift to ensure the renovation is worth doing.
UK renovation costs vary enormously by scope. A cosmetic refresh (paint, flooring) might cost £5,000-£10,000. A standard refurbishment (new kitchen, bathroom, rewire) runs £25,000-£45,000 for a 3-bed house. A full gut renovation can exceed £80,000. Our tool gives an itemised estimate for your specific project.
Kitchen and bathroom renovations typically offer the best return — a £7,000 kitchen can add £15,000-£20,000 in value. Loft conversions (£20,000-£50,000) can add 10-15% to property value. Extensions and additional bedrooms also perform well. Our tool helps you compare cost vs value uplift.
The industry standard is 10-15% contingency for straightforward refurbishments and 15-20% for older properties or structural work. Victorian and pre-1930s properties often reveal unexpected issues once work begins. Our tool adds customisable contingency to your total.
It depends on your strategy. BRRR investors renovate to force value and refinance out their cash. Standard BTL investors may do a basic refresh to attract tenants. The key is ensuring the renovation cost is justified by increased rent or property value. Our Deal Analyser pairs perfectly with this tool.
The more detailed your specification, the more accurate the quotes. Vague briefs lead to vague (and often inflated) quotes. Use our Renovation Spec tool to create an itemised room-by-room brief, then send it to 3+ contractors. This ensures everyone is quoting the same scope.
