Discount matrix

One screen, every model you sell. Key the discount you can do against list and your cash, HP and PCP prices go live across the marketplace immediately. This is the fastest way to price a whole range — minutes, not days.

Data connections

What Ostler is running on. Anything marked demo is using example data — connect the live source and every screen that depends on it upgrades at once, with no other change.

Keys are held server-side in production; this panel configures which provider each capability uses. The vehicle enquiry and MOT history services are free government APIs — registration takes days, not money. Valuations and imagery are commercial contracts.

Fleet board

Every vehicle, every status, one glance. Tap a row for documents, history and actions. Drivers keep their own data current through the Ostler app on their phone — you never chase a mileage or a photo again.

Grey fleet — your duty of care, discharged

Employees driving their own cars on your business are your legal responsibility: licence, business-use insurance, MOT, roadworthiness. Their own Ostler app already holds all of it — this board is simply your visibility. No forms, no chasing.

DriverCarLicence checkBusiness insuranceMOTDeclaration

Licence checks run against DVLA with driver consent, quarterly. A lapsed item flags here the day it lapses — and Isla nudges the driver before you ever have to.

Operator’s Licence

Two of your vehicles are over 3.5 tonnes, so you hold an O-licence — and with it a set of legal duties the DVSA can ask you to evidence at any time, at the operating centre, going back fifteen months. This board keeps that evidence current without anybody keeping a folder.

Maintenance planner — required to be planned forward, not recorded backward

Safety inspections at your declared frequency, scheduled ahead. This planner is the single document most commonly asked for at a DVSA visit, and the one most operators cannot produce.

Daily walkaround checks

Drivers complete the guided walkaround in their own Ostler app before first use — the same camera flow they already know, with the DVSA checklist behind it. Defects and nil-defect reports are both recorded, timestamped and photographed. Kept fifteen months automatically.

Drivers

Licence categories, Driver CPC hours, digital tachograph cards and medicals — each with its own expiry, each one an enforcement point.

Evidence pack

The DVSA turn up, or your O-licence comes up for review, or an insurer asks. One button, everything they will ask for, in order.

In production this generates a dated PDF bundle: maintenance planner, inspection sheets, brake tests, defect reports, tachograph download log, driver records and licence checks — with a signed index page.

Isla's suggested bookings

She reads what's due, checks the vehicle's quiet days from its journey pattern, and proposes a slot at a vetted garage. One tap books it — confirmation to you and the driver.

Booked jobs are tracked to completion, invoices filed against the vehicle, and the cost feeds your cost-per-mile automatically.

Defleet — the appraisal does the selling

When a vehicle's time is up, its driver films the guided walkround in their app. Isla writes the trade appraisal, and the vehicle goes out to the dealer bidding desk — or onto the Ostler private marketplace when retail money beats trade money. You watch it happen from here.

Electric transition — vehicle by vehicle

Not a policy, a verdict per vehicle. Isla weighs the duty cycle, the mileage, where it sleeps and the tax position, and tells you which ones should switch at their next replacement and which honestly should not.

The tax arithmetic

This is where fleet electrification pays for itself — and it is almost always larger than the fuel saving.

Company car taxA few per cent on electric against 25–37% on petrol. On a £40,000 car that is typically £300–450 a month back in a higher-rate taxpayer’s pocket — which is why salary sacrifice on EVs is the strongest employee benefit currently available in the UK.
Employer-paid charging is not a fuel benefitElectricity is not treated as fuel, so paying for home or workplace charging carries no additional taxable benefit. Most employers do not know this.
Reimbursement rates differ by where they chargeHMRC’s advisory rate for electric company cars distinguishes home charging from public charging — currently around 7p and 15p a mile respectively. Paying one flat rate either overpays or short-changes your drivers.
Vans and HGVs are a different question entirelyElectric vans work on predictable urban routes returning to base. Electric HGVs at 18 tonnes are still a specialist purchase with real range and payload penalties — anyone telling a general haulier otherwise is selling something.

Replacement pipeline

Isla flags each vehicle as it approaches the sweet spot — lease end, warranty cliff, value curve. Every route priced side by side: the Ostler comparison you know, at fleet scale.

Petrol or electric? The honest answer for your driving, not the sales pitch

Can you actually live with one?

Three questions decide it. Charging is what makes or breaks EV ownership — not range, and not the map.

Company car? This is where it gets interesting

Benefit-in-kind on an electric company car is a few per cent. On petrol it is commonly 25–37%. For a higher-rate taxpayer that difference is usually hundreds of pounds a month — the single largest saving available to most drivers, and the reason company-car EVs still make sense even as the private case weakens.

What nobody selling you an EV mentions

Road tax arrived in April 2026. Electric cars pay VED like everything else now — and anything over £40,000 list also carries the expensive-car supplement from years two to six. That is several hundred a year that did not exist before.
Used values are still falling. Used EV prices are down roughly a tenth year on year, and the industry’s own forecasters name the 2028 emissions targets as the next likely step down. Buying used can be a bargain or a falling knife depending entirely on the model.
Battery health is the real question on a used EV. Not mileage, not age — state of health. Ask for a battery health certificate before you buy anything second-hand, and treat its absence as a negotiating point.
Public charging is not cheap. Home charging is the whole economic case. Without off-street parking the running-cost advantage largely disappears — which is why the first question above is the one that matters.
