Fixed Price vs Day Rate: Which Is Better in 2026?
It’s one of the most debated questions in the trades – fixed price or day rate? The honest answer is neither is universally better. What matters is knowing when to use each one and how to protect yourself either way.
What Is a Day Rate?
A day rate is a set amount you charge for each day you work, regardless of exactly how long the job takes within that day. Most UK tradespeople charge somewhere between £200 and £450 per day in 2026, depending on trade, experience, and location.
What Is a Fixed Price?
A fixed price quote means you agree a total cost for the entire job upfront – materials and labour included. The customer knows exactly what they’re paying before work starts. If the job takes longer than expected, that’s your problem. If you finish ahead of schedule, that’s your reward.
Day Rate – Pros and Cons
Pros
- Simple to explain and easy to quote
- Protects you if the job is more complicated than expected
- Works well when the full scope isn’t clear upfront
- Good for jobs with unknown variables – old properties, hidden pipework, structural surprises
Cons
- Some customers feel uneasy not knowing the final cost
- Can look more expensive on paper than a fixed-price competitor
- Harder to win larger planned jobs where customers get multiple quotes
- Customers can feel like they’re watching the clock
Fixed Price – Pros and Cons
Pros
- Customers love the certainty – no bill shock at the end
- Stronger position when competing for larger jobs
- Rewards efficiency – finish faster and your hourly rate goes up
- Looks more professional in a written quote
Cons
- You carry the risk if the job overruns
- Dangerous on jobs with unknowns – one surprise can wipe out your margin
- Requires accurate estimating, which takes experience
- Scope creep becomes a problem if the customer adds to the job mid-way
When to Use a Day Rate
A day rate makes sense when:
- The scope isn’t fully clear – repairs, investigations, or jobs in older properties where you don’t know what you’ll find
- The customer keeps changing their mind – a day rate protects you when the brief is moving
- It’s a small call-out – for anything under a day, an hourly rate is cleaner
- Materials are being supplied by the customer – you’re selling your time, not a complete package
When to Use a Fixed Price
A fixed price works best when:
- You’ve fully surveyed the job and know exactly what’s involved
- You’re competing against other quotes – fixed pricing removes the uncertainty that costs you work
- It’s a straightforward, repeatable job – fitting a bathroom suite, rewiring a room, installing a kitchen
- The customer is planning ahead – homeowners budgeting for a renovation want a number they can work with
The Hybrid Approach Most Experienced Tradespeople Use
Use both – depending on the job
- Day rate for investigative, repair, or reactive work
- Fixed price for planned installations and larger projects
- Hourly rate for small call-outs and minor repairs
How to Protect Yourself on Fixed Price Jobs
- Always survey before you quote – never give a fixed price based on a description over the phone. See the job yourself.
- State what’s included – and what isn’t – “Supply and fit one consumer unit” is a fixed price. “All electrical work” is not.
- Build in a contingency – add 10–20% to your time estimate to cover minor surprises.
- Have a variation clause – make it clear that unforeseen issues will be quoted separately before work continues.
- Get it in writing – always send a written quote the customer has confirmed.
What Do Customers Actually Prefer?
Most residential customers prefer a fixed price. Commercial clients and property developers tend to be more comfortable with day rates on larger or longer-running projects. If you’re targeting homeowners, fixed pricing with a clear scope will generally win you more work.

Use day rate for reactive, repair, or investigative work where the scope is unclear. Use fixed price for planned jobs where you have fully surveyed the work and know exactly what is involved. Most experienced tradespeople use both depending on the job type, day rate protects you on unpredictable jobs, fixed price wins more planned installation work.
UK tradespeople typically charge between £200 and £450 per day in 2026, depending on trade, experience, and location. Specialist trades and those in London and the South East generally command rates at the higher end. Calculate your own minimum viable day rate by adding your target income to annual business costs, dividing by your billable days per year, and adding your profit margin.
Always survey the job in person before quoting, never give a fixed price over the phone. State clearly what is and is not included in your quote. Build in a 10–20% contingency on your time estimate. Include a variation clause specifying that unforeseen issues will be quoted separately. Get written confirmation from the customer before starting.
If the overrun is due to unforeseen circumstances outside the original scope, hidden damage, asbestos, structural surprises, issue a variation quote before continuing work. Get written sign-off from the customer. If the overrun is simply because you underestimated the time, that is your cost to absorb. This is why a contingency buffer in every fixed price quote is essential.
Fixed price is more profitable when you are efficient, if you finish ahead of your estimated time, your effective hourly rate goes up. Day rate is safer on complex or unknown jobs where you cannot confidently estimate the time. The most profitable tradespeople use fixed price on well-scoped planned work and day rate on reactive, repair, and investigation work.
Most residential customers prefer a fixed price, they want to know their total commitment before agreeing to proceed. Commercial clients and property developers are generally more comfortable with day rates, particularly on longer-running projects. If you are competing for domestic homeowner work, a clear fixed price quote will win more jobs than an open-ended day rate.
