Field Service Route Optimization Guide 2026
The Reality:
Poor routing costs field service businesses time, fuel, and job capacity. You're likely fitting fewer jobs into a day than you should. With better routing, you can reduce travel time and free up capacity without extending hours.

Route optimization isn't about working longer hours—it's about eliminating wasted travel time between jobs. Here's how to increase your daily job capacity by 30-40% using free tools and proven strategies, backed by real numbers from UK trade businesses.
The Real Cost of Bad Routing
Let's quantify what unoptimized routing actually costs you. Most trade business owners know it's inefficient but haven't done the math on the real impact.
The 5-Job vs 7-Job Day
| Metric | Poor Routing (5 jobs) | Optimized (7 jobs) | Difference |
|---|---|---|---|
| Work time per job | 60 mins | 60 mins | - |
| Travel time per job | 35 mins avg | 20 mins avg | -15 mins |
| Total work time | 5 hours | 7 hours | +2 hours |
| Total travel time | 2h 55m | 2h 20m | -35 mins |
| Total day length | 7h 55m | 9h 20m | +1h 25m |
| Miles driven | 58 miles | 42 miles | -16 miles |
| Revenue (£80/job avg) | £400 | £560 | +£160 |
| Fuel cost (30mpg, £1.50/L) | £10.60 | £7.70 | -£2.90 |
Annual Impact:
- Extra revenue: £160/day × 230 working days = £36,800/year
- Fuel savings: £2.90/day × 230 days = £667/year
- Vehicle wear reduction: 3,680 fewer miles = ~£550/year maintenance savings
- Total annual benefit: £38,017
Note: This assumes you can find the additional customers to fill 7 jobs/day. Even improving from 5 to 6 jobs yields £18,400/year additional revenue.
The Hidden Costs
Beyond fuel and time, poor routing creates:
- Customer dissatisfaction: Late arrivals, rushed jobs, narrower service windows
- Technician burnout: More time in van = less job satisfaction = higher turnover
- Lost emergency capacity: No buffer to slot in urgent/premium jobs
- Reduced service area: Can't profitably serve customers 15+ miles away
Geographic Clustering Strategy
The #1 route optimization principle: Minimize the area you cover in a day. Five jobs in a 2-mile radius beats five jobs spread across 15 miles every single time.
The Postcode Clustering Method
Organize your customer base by postcode district (first 3-4 characters: SW1, M14, EH3). Then batch jobs by area, dedicating specific days to specific zones.
Example: London Plumber's Weekly Zones
- Monday: SW postcodes (Wandsworth, Wimbledon, Clapham)
- Tuesday: SE postcodes (Greenwich, Lewisham, Bermondsey)
- Wednesday: N postcodes (Islington, Finsbury Park, Tottenham)
- Thursday: E postcodes (Stratford, Hackney, Tower Hamlets)
- Friday: W/NW postcodes (Hammersmith, Brent, Camden)
Result: Average drive time between jobs drops significantly, freeing up capacity for more jobs.
When to Break the Clustering Rule
Premium work justifies geographic deviation:
- Emergency callouts: Charge 50-100% premium to make the detour profitable
- High-value jobs: £500+ jobs justify 30-40 minute drives
- New customer acquisition: First job in new area = future clustering opportunity
- End-of-day flexibility: Last job can be "on the way home" even if slightly off route
Rule of thumb: Only deviate from your daily zone if the job pays 2x your hourly rate to account for travel time.
Building Clusters Proactively
Once you land one customer in a new postcode area:
- Door-to-door marketing: Flyer the surrounding streets (neighbors see your van, ask who you work for)
- Referral incentive: "£10 off your next visit if you refer a neighbor"
- Pricing strategy: Charge 10-15% less for customers within 1 mile of existing clients
- Target advertising: Facebook ads targeting specific postcode districts where you have presence
Time-of-Day Optimization
When you schedule jobs matters as much as where. Traffic, customer availability, and job complexity all vary by time of day.
The Optimal Daily Schedule Structure
8:00-9:00am: Complex Job #1
Start with your most complex job while you're fresh. Customer is home (residential) or just opened (commercial). No prior delays to make you late.
9:30-10:30am: Quick Jobs (2-3 jobs)
Knock out 2-3 quick jobs (30-45 min each) in tight geographic cluster. Traffic is lighter post-rush hour. Build momentum and revenue.
11:00am-12:00pm: Medium Job
60-90 minute job before lunch. Avoid starting complex work right before lunch (mental fatigue, rushing to finish).
12:00-12:30pm: Lunch + Admin
Eat lunch, update job notes, send invoices, plan afternoon route adjustments. Park somewhere central to afternoon jobs.
12:30-2:30pm: Complex Job #2
Your second complex job. Post-lunch energy, enough time to complete without rushing. If it overruns, still have buffer for last job.
3:00-5:00pm: Final Jobs (2-3 jobs)
Quick jobs or routine maintenance. Keep these close together and near your home/depot. End at location that minimizes commute home.
Traffic-Aware Scheduling
UK traffic patterns create predictable windows. Use them strategically:
- 7-9am: Avoid cross-town travel. Schedule first job close to your home or in same direction as traffic flow.
- 9am-3pm: Best window for longer drives between zones if needed. Traffic is 30-40% lighter.
- 3-6pm: School run + rush hour. Keep jobs within 5-mile radius during this window.
- 6pm+: Evening jobs (if offered) should be within 10 miles of your home for reasonable commute after.
The "Last Job" Strategy:
Always make your final job of the day geographically closest to home. A 45-minute job that ends 5 minutes from home beats a 45-minute job that ends 30 minutes from home—that's 25 minutes of unpaid drive time you'll never get back. Over a year, that's 96 hours wasted (£4,000-£5,000 in lost potential revenue).

When to Upgrade from Free to Paid
Switch to paid routing software when ANY of these are true:
- Multiple technicians: Coordinating 2+ people requires centralized routing
- 20+ jobs per week: Manual route planning takes 45+ mins/day (£180/week wasted at £40/hour)
- Customer time windows: "Between 2-4pm" appointments require constraint-aware optimization
- Real-time changes: Emergency jobs, cancellations need instant re-routing
- Integration needs: Want routing connected to scheduling/invoicing software
ROI on Paid Routing Software:
Cost: low monthly subscription
Time saved: reduced daily planning time
Fuel saved: fewer miles with tighter routing
Extra job capacity: more slots in the week
The value comes from freeing up billable work and cutting wasted travel, even on a modest schedule.
Daily Route Planning Process
The best routing software in the world won't help if you don't have a consistent planning process. Here's a short morning routine that saves significant time during the day.
Night Before (5 minutes)
- Review tomorrow's confirmed jobs - Check for cancellations, time window requirements
- Identify the geographic center - Where are most jobs clustered?
- Flag complex jobs - Which jobs need extra time, special equipment, or problem-solving?
- Load equipment - Van stocking based on next day's job types (see our van stock guide)
Morning Of (10 minutes)
- Check for last-minute changes - Cancellations, new emergency bookings, customer requests
- Enter addresses into routing tool - Google Maps, Circuit, or your job management software
- Apply optimization constraints:
- Start location: Your home or depot
- End location: Ideally near home
- Time windows: "Must arrive between 2-4pm" jobs
- Job duration: Factor in realistic work time per stop
- Breaks: Plan lunch location centrally
- Let the tool optimize - Review suggested order, make manual adjustments if needed
- Send departure - Text/email customers: "Good morning. I'll be with you around [time]. Thanks."
During the Day
- Update customers proactively: Running 15+ mins late? Text them immediately.
- Flag delays immediately: Job taking longer? Adjust remaining schedule and notify next customer.
- Slot emergencies strategically: Can you fit an emergency job between 3pm and 4pm without disrupting the rest?
- Track actual vs planned: Mental note of which jobs took longer than expected (adjust estimates for next time)

Common Mistakes to Avoid
1. Optimizing for Distance Instead of Time
Shortest route ≠ fastest route. A 12-mile route via motorway often beats an 8-mile route through city center traffic. Always optimize for time, not miles.
2. Over-Optimizing at the Expense of Customers
Don't reschedule a loyal customer's preferred time slot just to save a few minutes of drive time. Relationship value exceeds routing efficiency sometimes.
3. Ignoring Traffic Patterns
Your route might be optimal at 10am but terrible at 4pm. Use traffic-aware routing tools or manually adjust for known congestion times.
4. Not Accounting for Job Complexity
Treating all jobs as equal duration kills your schedule. A "30-minute" tap replacement is not the same as a "30-minute" diagnosis of an intermittent fault. Build in buffer time for diagnostic work.
5. Failing to Update Customer Expectations
If you switch from "I'll be there Tuesday" to "I only serve your area on Thursdays now," communicate why (better reliability, on-time arrivals). Most customers prefer consistent scheduling over flexibility.
The Bottom Line
Route optimization isn't sexy. It won't make a good Instagram post. But it's the difference between earning £40,000/year and £60,000/year from the exact same skills and working hours.
What Good Routing Actually Gives You:
- 30-40% more job capacity without working longer days
- 20-30% less fuel cost from reduced mileage
- Lower vehicle wear = £400-£600/year maintenance savings
- Happier customers from on-time arrivals and wider service windows
- Less stress from eliminating frantic "who do I see next?" decisions
- Scalability = when you hire, they follow established routing systems
Start with free tools (Google Maps multi-stop or Circuit). Implement postcode zone batching. Track your results for 30 days. You'll see the impact immediately.
The businesses winning in 2026 aren't working harder. They're working smarter by eliminating the 90 minutes per day wasted driving between poorly planned jobs.
