Job Estimate Template

Professional job estimate template for any trade, with price ranges, assumptions, exclusions, and clear caveats. Free PDF download.

What is it?

A job estimate is a professional document that gives the customer an approximate cost for proposed work, based on an initial assessment. It usually presents a price range rather than a single fixed figure, alongside the assumptions the estimate relies on, the factors that could change the price, and a clear statement that the final cost may differ. It is not a fixed-price commitment like a quote, but it should still be as accurate and realistic as you can make it so the customer can plan their budget.

About this template

An estimate is the right document to provide when the full scope of a job is not clear upfront. Unlike a fixed-price quote, an estimate gives the customer an informed price range based on what you can see, while acknowledging that the final cost may vary once work begins. This is particularly important for jobs where hidden issues are common: fault finding, working on older properties, or larger projects where conditions are revealed only as work progresses. A well-structured estimate manages customer expectations, protects your profit margin, and shows that you take a professional, honest approach to pricing.

When to use

  • When the full scope of work cannot be determined without opening up walls, floors, or fittings
  • For fault finding or diagnostic work where the time required is unpredictable
  • When working on older properties where the condition of existing installations is unknown
  • For large or phased projects where the customer wants a ballpark figure before committing
  • When a customer asks roughly how much before you have done a full survey
  • For insurance or planning purposes where an approximate cost is needed early

Tips

  1. 1Always explain the difference between an estimate and a quote to the customer. Many people assume they are the same and expect a fixed price
  2. 2Provide a realistic price range rather than an optimistic low figure. It is better to underpromise and overdeliver on cost than to surprise the customer later
  3. 3Document your assumptions clearly so that if the price does change, the customer can see exactly why and the conversation stays straightforward
  4. 4Offer to convert the estimate into a firm quote once you have done a thorough survey or once preliminary work has revealed the full scope
  5. 5Keep records of your estimates and compare them with the final invoices: this steadily improves your estimating accuracy and protects your margins

Frequently asked questions

What is the difference between an estimate and a quote?

An estimate is an approximate price based on an initial assessment, and the final cost may end up higher or lower. A quote is a fixed-price commitment that you are generally obliged to honour once the customer accepts it. Use an estimate when there are genuine unknowns you cannot price accurately, and a quote when the scope is fully defined. Most customers prefer a quote where possible, so it is good practice to offer to convert your estimate into a firm quote once the full scope of the job becomes clear.

Is a job estimate legally binding?

No, an estimate is not legally binding in the way an accepted quote is. However, under the Consumer Rights Act 2015 the final price you charge must be reasonable and broadly in line with the estimate you gave. If the actual cost is heading significantly higher than estimated, you should inform the customer as early as possible and get their agreement before continuing the work. Substantially exceeding an estimate without any communication can lead to a payment dispute and lasting damage to your reputation.

How accurate should a job estimate be?

As a general rule, aim for your estimate to land within 10 to 20% of the final cost. Presenting a range (for example £1,500 to £2,000) rather than a single figure is honest and accounts for the uncertainty. Be clear about what you can and cannot see, and explain the specific factors that might push the price toward the higher end. Customers consistently respond better to honesty than to an artificially low number that creeps upward once the job is underway and trust starts to erode.

When should I give an estimate instead of a quote?

Give an estimate when you cannot determine the full scope of work. For example when work is hidden behind walls or under floors, when diagnosing an intermittent fault, or when scoping a larger job from plans alone. If the job is straightforward and you can see everything you need to price it accurately, a fixed-price quote is more appropriate and is what most customers expect. Using an estimate for a job you could quote firmly can make you look unsure and may cost you the work.

Should I charge for providing an estimate?

For a quick verbal or email estimate, customers do not expect a charge and most tradespeople provide these free. If the estimate requires a detailed site survey, testing of existing installations, or a significant time investment, it is reasonable to charge a survey fee, typically in the range of £50 to £150 depending on complexity. Make any fee clear before you attend the property. Many tradespeople deduct this survey fee from the final bill if the customer goes ahead, which keeps the charge feeling fair.
