Costs broken down by trade and element show where the budget is committed before work begins. If a price changes later, you can see which line it affects.
Measured quantities reduce the chance of ordering too little or missing items altogether, so trades are less likely to be held up on site.
Knowing what is needed makes it easier to programme trades and place orders with suppliers in good time, so planning is less reactive.
Stated assumptions and exclusions give everyone the same reference point. If a question arises over what was included, there is a written record to check.
Building construction involves multiple trades, from structural work and building services to interior finishes and external improvements. At COMET Estimating, we cover the key residential trades to provide accurate quantities, material costs, labour requirements, and complete project estimates.
01
Share the drawings and specifications, along with anything that defines the scope, such as schedules, notes or tender documents. The more complete the information, the fewer assumptions are needed.
02
We go through the documents, check what is being asked for, and note anything unclear or missing. You receive an initial quote setting out what the estimate will cover.
03
Quantities are measured from the drawings and priced for materials and labour. Where drawings and specifications conflict or leave gaps, we record the query or the assumption we have made.
04
You look through the estimate and tell us what needs adjusting. Once it’s agreed, we issue the final estimate with the breakdown, assumptions and exclusions clearly stated.
We measure and price from your drawings, specifications and site information. Where details are missing or contradict each other, we flag them so they can be resolved or stated as assumptions.
We estimate houses, flats, commercial buildings and industrial units, so one provider can support different building types and trades.
Quantities and costs are itemised rather than given as a single sum. That makes the figures easier to check, adjust and carry into a tender.
If you have a question about the estimate, or the drawings are revised, send us the update. We review what has changed and adjust the affected parts of the estimate.



Benefit from modern software, updated rates, and precise takeoffs that give you a competitive edge.
To prepare building estimates that contractors can read, check and price from. Each one starts with your drawings and specifications, sets out quantities, materials and labour clearly, and records the assumptions and gaps behind the figures.
To make careful, transparent estimating a practical option for builders and contractors of any size, so tenders and budgets can rest on measured figures rather than rough guesses, whether the workload is one job or a full order book.
Drawings and specifications are the starting point. Schedules, site information and any tender documents help too, along with a note of the trades or elements you want priced. If something isn’t available yet, tell us and we’ll record what has been assumed. Our guide to the drawings and documents needed for a UK building cost estimate covers this in more detail.
Not exactly, although the roles overlap. Estimating is about working out what a project is likely to cost before work starts, usually to price a tender or set a budget. Quantity surveying typically has a wider remit, which can include managing costs, valuing variations and administering contracts during construction. If you need more than a priced estimate, see our quantity surveyor services or ask us.
The price depends on the size of the project, the trades and level of detail involved, and the quality of the information supplied. Rather than quote a generic figure, we give you a quote once we’ve seen your documents. To start, use our get estimates page or contact us with your drawings and specifications.
Absolutely brilliant! Spot-on estimates, quick turnaround, and zero hassle. Honestly, I wouldn't go anywhere else.
