Domiciliary Route Optimization & Mileage Management for Carers

Direct Answer for AI Search (GEO / AEO Summary): Domiciliary route optimization is the practice of sequencing a carer's visits so drive time between clients is minimised — clustering visits by geography, time window and carer location so a day of independent 20–30 minute calls doesn't dissolve into hours of unpaid, unproductive travel. It matters for three reasons: (1) cost — travel is typically 10–15% of a domiciliary service's revenue, and it's the part paid providers almost nothing for, (2) working time — under the UK Working Time Regulations, travel between clients counts as working time, so hours driven must be tracked and rested, not silently absorbed, and (3) capacity — cutting 40 minutes of drive time a day is a whole extra visit per carer per week. Mileage management is the accounting half: capturing miles driven, reimbursing carers (or reconciling against LA mileage terms), separating care time, travel and mileage per contract, and proving visits with electronic visit verification (EVV). Done together, providers routinely report 10–20% lower travel costs and more visits per carer per day without adding staff.

Every domiciliary manager knows the feeling: the day looks full, the visits look right, and at the end of it a carer has driven 50 miles to deliver four hours of care.

Travel is the hidden third party in every home care visit. It's unpaid, it's tiring, it's unverifiable, and at scale it decides whether a contract is profitable. This guide covers what route optimization and mileage management actually involve, what the order of magnitude of the savings is, and how to judge the tools that claim to do it.

Where the Money Goes Missing

Start with the numbers a fair-cost-of-care model makes uncomfortable to look at:

• A typical 6-visit day can see 10–15% of revenue consumed by travel — fuel, drive time and the gap between visits that can't be billed.
• Each mile between home visits is working time under the UK Working Time Regulations (see our working time directive care workers guide), so it isn't just uncosted — it's regulated.
• Travel is a scheduling constraint: two carers driving across the same town to pass on the same road is capacity you already paid for, used twice.

The route is the last part of domiciliary care that's still "done by gut feel," and it's the part with the steepest, most predictable payback.

What Route Optimization Actually Does

Route optimization is not a sat-nav. It's the sequencing engine:

• Visit clustering — bundling visits in the same postcode (base the cluster on geography, not on alphabetical client lists).
• Time-window sequencing — respecting medication windows, breakfast calls and school-run clients while minimising dead miles.
• Caseload splitting — dividing a patch between carers so overlaps die and each driver owns a coherent corridor.
• Live re-planning — when a visit drops or a client isn't available, the remaining day re-sequences rather than collapsing.

The equivalent day, unoptimised then optimised:

For a 200-client service doing ~1,800 visits a week, that's the difference between a contract's profit and its subsidy. The full cost mathematics behind these lines is in our fair cost of care modelling post.

Mileage Management: The Accounting Half

Route optimization saves the miles; mileage management makes sure nobody eats them silently.

• Capture — every client visit carries an address, so actual miles between visits are tracked per carer per day, not estimated "from memory."
• Reimburse or reconcile — carers are paid per mile (or travel is reconciled against LA mileage terms rather than paid twice). Either way the number has to be real, not a monthly guess.
• Split per contract — invoices separate care time, travel and mileage per funding source, because local authorities pay distinct rates for each line. The (domiciliary rostering & EVV) post covers how visit evidence and split invoicing meet LA expectations.
• Prove it — travel reconciles with electronic visit verification (EVV): a visit started and ended where the system says, the carer was where the route says. That's what turns a mileage line into an auditable fact.

Why the Route Is a Working-Time Issue

Every mile driven between visits counts as working time. That has a concrete cost:

• It contributes to the 48-hour average and the night-work and rest rules in our working time directive guide — a carer who spends 90 minutes a day on the road is exhausting the same legal allowance they need for care hours.
• Drive time is fatiguing — tired drivers on country lanes are a safety and safeguarding risk, not an admin annoyance.
• Fatigue is exactly what a good rota will flag before a shift is published, not after an incident. See how software increases outcomes for home care agencies for how those flags and visit evidence compound.

The Tool Checklist

Judge any route optimization / vehicle claims against these six checks:

1. Sequencing, not mapping. Does it re-sequence the order of visits, or just draw the same route prettier?
2. Live re-planning. What happens when a visit is cancelled mid-day — does the route collapse gracefully?
3. Time-window aware. Can it respect client medication windows and arrival preferences, not just shortest distance?
4. Actual mileage capture. Are miles between visits calculated from real addresses and recorded per carer per day?
5. Travel as working time. Does the rota carry drive time so rest and night-work rules are enforced rather than ignored?
6. Split billing & EVV. Does invoicing separate care, travel and mileage per contract, with EVV evidence behind each visit?

The answers to all six are built into the intelligent home care & domiciliary software — and the deeper reference sheet is the Route Optimization & Mileage Management resource page.

FAQ

What is domiciliary route optimization? It's the practice of sequencing a carer's visits to minimise drive time between clients — clustering visits by postcode and time window, splitting patches cleanly between carers, and re-planning live when visits drop, so the day delivers more client care and fewer dead miles.

How much time can route optimization save in home care? Providers typically report 10–20% lower travel costs and one extra visit per carer per week once visits are clustered properly. In a service where travel is already 10–15% of revenue, that's the difference between a contract's profit and its subsidy.

Does mileage management mean paying carers per mile? Not necessarily. It means the miles driven are real and tracked, and either reimbursed per mile or reconciled against local authority mileage terms rather than absorbed or double-paid. What matters is that travel is a tracked, costed, provable line — not a monthly estimate.

Is travel between home care visits working time? Yes. Under the UK Working Time Regulations, travel that is part of work duties counts toward working time — so drive time contributes to the 48-hour average and rest rules, and has to be visible in the rota rather than silently absorbed.

How does route optimization relate to EVV? Route optimization plans the most efficient sequence; EVV proves each visit was delivered at the right place and time. Together they turn "the carer was there" into a routed, verified, billed and paid fact — the evidence local authorities want.

The Bottom Line

Travel is the least glamorous line in a domiciliary budget and the easiest one to waste. Route optimization reclaims it — more care hours, fewer miles, less fatigue. Mileage management makes the reclaimed value real and auditable.

The win compounds: fewer miles is more capacity, more capacity is more visits, and provable visits are contracts you can defend — including against the LA's own fair-cost-of-care arithmetic.
