Estimating Takes Days
Pricing an extension means calculating blockwork, concrete, lintels, roof structure, and dozens of material quantities. Most builders spend days on detailed quotes.
Building Regs Complexity
Part A structure, Part B fire, Part L energy, Part M access — every project touches multiple regulation areas that affect your spec and costs.
Underquoting Kills Margins
Miss a cost line on a £40,000 extension and you could lose thousands. Manual estimating means missed items and thin margins.

Making Tax Digital and Builders
From 6 April 2027, Making Tax Digital for Income Tax covers sole traders and landlords whose qualifying income was over £30,000 in the 2025-26 tax year. Qualifying income is your self-employment and property income beforeexpenses, so it's your turnover, not your profit. If you're in, you keep digital records and send HMRC a short update every quarter.
The app keeps your books as you work: invoices become income, receipt photos become expenses, and the quarterly figures are ready to export for you or your accountant to submit. Filing straight from the app isn't available yet.
Worked example
Say a builder turns over £55,000 in 2025-26 and spends £30,000 on materials, skip hire and plant.
- Turnover (what HMRC tests)
- £55,000
- Profit after costs
- £25,000
- Over £30,000?
- Yes, in from 6 April 2027
Their first quarterly update covers 6 April to 5 July 2027 and is due by 7 August 2027, even though their profit is under £30,000.
Illustrative figures, not a statistic. Rules from GOV.UK: eligibility, qualifying income, quarterly updates.
