About the starting figures
The estimator opens with a day rate of £400, a seven hour day, a 15 percent contingency and some hour estimates. Those numbers are placeholder assumptions so the table is not empty. They are not an average, a market price or our price. Replace them with figures from real quotes as soon as you have them.
Running costs start at zero because they depend entirely on which providers you choose. Check each provider's current price and enter it.
How the sums work
- The hourly rate is the day rate divided by the hours in a working day.
- Each ticked line is its hours multiplied by the hourly rate. Building pages and adding content are multiplied by the number of pages as well.
- Contingency is a percentage of the build work.
- Monthly running costs are multiplied by twelve; yearly ones are added as they are.
- If you tick the VAT box, 20 percent is added to the whole total. GOV.UK lists 20 percent as the standard rate. Tick it only if your quotes will include VAT.
Using it with real quotes
When a builder sends a quote, put their figures in: either their day rate and hours, or their fixed price split across the lines. Download each version, so you can compare quotes side by side. If one quote is far lower, check which lines it leaves out.
The budget guide explains each part of a budget and how to compare quotes fairly.
