The Landscape

Why Most Builders Are Still Using Spreadsheets

Estimating software has existed for decades — but adoption in small and mid-size building firms remains low. The reason: most tools were built for large contractors, not renovation specialists.

Traditional platforms like EstimatorXpress and Buildxact require significant setup time, monthly subscriptions regardless of workload, and demand you manually enter measurements from drawings. For a builder doing 2–3 renovation projects a month, that overhead rarely makes sense. The newer category — AI-powered estimating — changes this equation entirely. RenoCalc was built by a working builder to go from floor plan to professional quote in minutes rather than hours.

Our Verdict

Which Tool is Right For You?

By Business Type

Renovation specialist: RenoCalc — no other tool does floor-plan-to-quote in minutes with full trade depth.

Need full project management: Buildxact — if you need CRM, scheduling, and estimating in one place and can absorb the cost.

New build / larger firm: EstimatorXpress — mature product with detailed outputs, though the learning curve is steep.

Sole trader / day-to-day admin: Tradify — affordable, mobile-friendly, great for invoicing, but not for renovation estimating.

Common Questions

Construction Estimating Software FAQ

What is the best estimating software for small builders in the UK?
For small builders doing renovation work, RenoCalc is the fastest option — it reads a floor plan and produces a detailed Excel quote in 3 minutes. For larger firms needing full project management, Buildxact offers a more comprehensive suite but at higher cost. For sole traders needing basic job admin, Tradify is popular and affordable.
How much does construction estimating software cost in the UK?
Costs vary widely. RenoCalc starts from £4.99 per quote (pay-as-you-go) or £19.99/month for unlimited quotes. Tradify is around £35/month, EstimatorXpress around £99/month, and Buildxact from £149/month. The right choice depends on your quote volume and whether you need project management features alongside estimating.
Can estimating software read floor plans?
Most traditional estimating software cannot — you have to manually input measurements. RenoCalc is currently the only UK renovation estimating tool that uses AI to read and analyse floor plans directly, extracting room dimensions and generating a full quote automatically. This is what reduces quoting time from 2–4 hours to under 3 minutes.
What's the difference between takeoff software and estimating software?
Takeoff software is used to measure quantities from drawings — it's the measurement stage. Estimating software then applies labour rates and material costs to those quantities to produce a price. RenoCalc combines both steps: it performs AI takeoff from a floor plan image and immediately generates a full cost estimate with no manual measurement step in between.
Is Excel good enough for construction estimating?
Excel works well for experienced estimators with existing templates, but building those templates takes significant time and they're prone to error when updated manually. RenoCalc outputs directly to Excel — so you get spreadsheet flexibility and live formulas, but with all measurements, quantities, and rates populated automatically by AI.
Which software is best for renovation work specifically?
RenoCalc was built specifically for renovation work — it covers all 12 trades commonly involved in a refurbishment (plastering, plasterboarding, electrical, plumbing, tiling, flooring, decorating, roofing, carpentry, and more) and generates a full materials shopping list alongside labour costs. General estimating tools like Buildxact are designed for new builds and lack renovation-specific trade depth.
