How long should a building quote actually take

Homeowners wonder why a quote takes three weeks. Builders wonder how it could possibly take less, given that quoting happens after dark, unpaid, at the end of a day on the tools. Both are asking the right question, and the honest answer depends on the job, the information, and the process.

The honest answer: it depends on the information

A quote is only as fast as the facts behind it. A boiler swap can be priced from two photos and a postcode. An extension needs a survey, drawings or at least firm dimensions, decisions about spec, and often subcontractor prices that arrive on someone else's timetable. When a quote is slow, the delay is usually not laziness, it is the builder waiting on missing information, or trying to find an evening in which to do a desk job properly.

That said, there are reasonable norms, and a builder who consistently sits outside them is losing work whether they know it or not.

Small jobs: a day or two

For repairs, fencing, small roofing jobs and single-trade work, 24 to 48 hours is the standard worth holding yourself to. The pricing itself takes minutes for anyone experienced. What kills small-job quotes is the queue: they wait behind bigger paperwork until the client, who usually has two or three other names in their phone, has already said yes to whoever answered first. On small work, speed converts more reliably than any other factor you control.

Extensions and lofts: days to two weeks

A proper extension quote needs a site visit, a read of the drawings, quantities taken off, subcontractor prices for anything you do not self-deliver, and an evening of assembly into a document worth signing. Done around a full working week, that legitimately lands at one to two weeks. Clients accept this happily when it is explained up front: "you will have the full written quote a week on Friday" is a promise, silence is a worry.

The trap is the other direction: quoting a five-figure job in an evening without a survey. Fast guesses on complex work are how builders buy jobs they later regret. The middle path is to compress the mechanical parts, the take-off, the arithmetic, the document formatting, and spend the saved time on the judgement calls that actually need a human. That is precisely what QS Quoter is for: it turns a description or drawings into a priced, itemised draft at your own rates, ready for checking and adjustment.

What legitimately slows a quote down

• Missing decisions. If the client has not chosen between a 3 metre and 4 metre projection, the quote cannot exist yet.
• Subcontractor prices. Your electrician also quotes at 9pm. Their turnaround is inside yours.
• Access to the property. No survey booked, no quote started, which is why the survey should be booked in the first phone call.
• Drawings still with the architect. Nothing useful can be priced from a sketch of a dream.
• The builder's own backlog. The honest one. Quoting is unpaid work done in personal time, and it queues behind paid work.

Most of these can be moved earlier rather than removed. The questions that surface missing decisions belong in the first conversation, and we keep a full list in questions to ask a client before you price anything.

How clients can speed the quote up

Homeowners are not passengers in this process, and the fastest quotes are usually the ones the client helped along. Three things make a genuine difference. First, have your decisions made before the survey, or at least know which ones are still open: a builder can price around one undecided item, but not six. Second, send everything you have in the first message, drawings, photos, a list of who is supplying what, rather than drip-feeding it across a fortnight of texts. Third, be straight about your timeline and who else is quoting, because a builder who knows the decision date can plan the work backwards from it. None of this obliges anyone to accept the first number that arrives. It just means the numbers arrive while you still care about them.

Fast and accurate is now a real option

For decades the trade-off was genuine: fast meant rough, accurate meant slow. The mechanical majority of quoting, measuring, multiplying, formatting, checking arithmetic, no longer needs to consume the evenings. What should remain human is the judgement: the state of the ground, the age of the wiring, the client who will change their mind four times. A good modern process uses software for the first part and the builder for the second, and gets a two-week quote out in two days without guessing.

Whichever tools you use, the standard to aim for is simple to state: name a date on day one, hit it, and send a document that was worth the wait. A guide to what that document should contain is in what a professional builder's quote should include.
