How to Price a Job: Complete Guide for UK Builders
Getting your pricing right is the difference between a profitable business and one that struggles. Price too high and you lose work to competitors. Price too low and you’re working for nothing — or worse, at a loss.
This guide walks you through exactly how to price construction jobs accurately, consistently, and profitably.
Why Accurate Pricing Matters
Every builder has horror stories: jobs that spiralled, quotes that didn’t account for hidden costs, clients who expected champagne on a lemonade budget.
Poor pricing leads to:
- Squeezed or negative margins
- Disputes with clients
- Rushed work to claw back time
- Reputation damage from unfinished or poor-quality jobs
Accurate pricing protects your profit, your reputation, and your sanity.
The Pricing Formula
At its simplest, job pricing follows this structure:
Total Price = Materials + Labour + Overheads + Contingency + Profit
Let’s break each element down.
1. Materials
List every material required for the job. Be specific — don’t estimate “some timber and screws.” Price each item using your trade account rates, not retail.
Tips:
– Add 10% for waste and offcuts
– Check current prices — material costs fluctuate
– Factor in delivery charges
Use a bill of quantities for larger jobs to ensure nothing is missed.
2. Labour
Calculate how many hours or days each task will take, then multiply by your labour rate.
Include:
– Your own time
– Employees
– Subcontractors (plumbers, electricians, etc.)
Be realistic. If a task takes you 6 hours on a good day, price for 7–8. Unexpected issues always arise.
3. Overheads
Overheads are the costs of running your business that aren’t tied to a specific job:
- Vehicle costs (fuel, insurance, maintenance)
- Tools and equipment
- Insurance (public liability, professional indemnity)
- Accounting and admin
- Phone, software, subscriptions
- Training and certifications
Calculate your annual overheads, then divide by the number of working days to get a daily overhead rate. Add this to every job.
Example:
– Annual overheads: £12,000
– Working days per year: 220
– Daily overhead rate: £55
4. Contingency
Construction is unpredictable. Hidden rot, unexpected drainage issues, supply delays — they all cost time and money.
Add a contingency of 5–15% depending on:
- Job complexity
- Property age and condition
- How well you know the site
- Client expectations
For straightforward new-build work: 5%
For renovation or period properties: 10–15%
5. Profit
This is what you actually take home after costs. Many builders forget to include profit, treating their labour rate as income — but that’s a mistake.
Your labour rate covers your time. Profit is the reward for running a business, taking risk, and delivering quality.
A healthy profit margin for construction work is 10–20% on top of all costs.

Pricing Methods
Day Rate
Charge a fixed daily rate regardless of the specific tasks completed.
Pros:
– Simple to calculate
– Reduces risk if scope changes
– Good for maintenance and smaller jobs
Cons:
– Clients may question value
– Harder to quote accurately for fixed-budget projects
Average UK builder day rates range from £200–£350 depending on trade and region. See our full breakdown in the builder’s day rate guide.
Fixed Price (Lump Sum)
Quote a single price for the entire job, based on a defined scope.
Pros:
– Clients know exactly what they’re paying
– Rewards efficiency — finish faster, earn more per hour
– Professional appearance
Cons:
– Risk sits with you if costs overrun
– Requires accurate estimating
– Scope creep can erode margins
Cost Plus
Charge actual costs plus an agreed percentage or fee.
Pros:
– Low risk for you
– Transparent for clients
– Good for uncertain or evolving projects
Cons:
– Clients may feel lack of control
– Less incentive to work efficiently
– Requires detailed record-keeping
Step-by-Step: Pricing a Job
Step 1: Site Visit
Never price a job without seeing it first. Photos and descriptions miss crucial details.
Look for:
– Access issues
– Existing condition
– Potential hidden problems
– Parking and storage
Step 2: Define the Scope
Write down exactly what’s included — and what’s not. Be specific.
Example:
“Supply and fit new kitchen including units, worktops, sink, and tiling to splashback area. Does not include appliances, flooring, or decoration.”
Step 3: Measure Up
Take accurate measurements. Calculate quantities for materials and estimate labour time for each task.
Step 4: Get Material Prices
Contact your suppliers for current prices. Don’t rely on old quotes — material costs change frequently.
Step 5: Calculate Labour
List every task and estimate hours. Multiply by your hourly or daily rate.
Step 6: Add Overheads and Contingency
Apply your daily overhead rate and contingency percentage.
Step 7: Add Profit
Apply your target profit margin (10–20%).
Step 8: Sense Check
Does the final number feel right? Compare to similar jobs you’ve done. If it seems too high or too low, revisit your assumptions.
Step 9: Present the Quote
Provide a clear, professional quote with:
– Itemised breakdown (optional, but builds trust)
– Payment terms
– Validity period
– Exclusions clearly stated
Common Pricing Mistakes
1. Underestimating Labour Time
Always add buffer. If you think it’s 3 days, price for 3.5.
2. Forgetting Overheads
Your van, insurance, and tools cost money. Include them.
3. No Contingency
Something will go wrong. Budget for it.
4. Treating Labour as Profit
Your time has a cost. Profit is separate.
5. Racing to the Bottom
Competing purely on price is a losing game. Compete on quality, reliability, and professionalism.
Using Software to Price Jobs
Spreadsheets work, but dedicated estimating software speeds up the process and reduces errors.
Options include:
– Cost Estimator’s professional estimating service
– Dedicated takeoff software
– Quote management apps
For complex projects, consider hiring a quantity surveyor to produce detailed cost plans.
Frequently Asked Questions
How much profit should I add to a job?
Aim for 10–20% net profit margin after all costs including your own labour.
Should I show clients my cost breakdown?
Optional. Some clients appreciate transparency; others just want a bottom-line price. Itemised quotes can build trust but also invite line-by-line negotiation.
What if the client wants a cheaper price?
Don’t automatically discount. Instead, discuss scope — what can be removed or simplified? Protect your margin.
How do I handle price increases mid-job?
Include a clause in your quote: “Prices valid for 30 days. Material cost increases beyond this period may be passed on.”
Should I charge for quotes?
For large or complex jobs, yes. A nominal fee (£50–£200) filters out time-wasters and demonstrates professionalism. Deduct it from the final invoice if they proceed.
Summary
Accurate pricing protects your business. Follow this formula:
Materials + Labour + Overheads + Contingency + Profit = Job Price
Take time to measure properly, get current prices, and build in buffers. Present quotes professionally and stand by your pricing.
