Short answer

E-rostering is the electronic system an NHS employer uses to build and publish staff rotas. Staff usually view their roster and submit leave, day-off and shift requests through a mobile app or web portal, and a rostering team and managers build the roster within the employer's rules. NHS England's good practice guidance says rosters should be approved and published at least six weeks before they are worked (ideally 12 for managers), that leave should be spread evenly across the year, and that rosters must be fair, safe and within budget. Request limits, cut-off dates and whether you can self-roster are set by your own trust's e-rostering policy, so ask your manager or e-rostering team for it.

This explainer is for NHS staff who work rotas and want to understand why leave requests are approved or refused, how far ahead things are decided, and what the idea of self-rostering means. It describes the common concepts that the main e-rostering systems share, such as HealthRoster, Optima and RosterPro, and does not cover any one product's screens.

What e-rostering is

NHS England and NHS Improvement's Nursing and midwifery e-rostering: a good practice guide (updated September 2019) describes e-rostering as a way to manage staffing ward by ward while giving trust boards assurance that quality outcomes are met and resources used efficiently. It is written for nursing and midwifery, and it says its principles can be applied to an electronic or manual rostering system for any staff group. It is guidance for managers rather than a policy document, and it is several years old, so treat it as the national good practice baseline and your trust's policy as the rulebook.

A good e-roster uses the following building blocks, which you will see under different names in different systems:

✓ Shift and duty patterns for the ward or team, tied to the required staffing levels.
✓ Staff availability: contracted hours, annual leave, sickness, study leave and any agreed working restrictions.
✓ Requests: leave requests and preferences for days off or shifts submitted by staff.
✓ Rules built into the system, such as rest periods and maximum working patterns, and limits on how many people can be on leave at once.
✓ Approval in two levels, then publication.
✓ Live updates for sickness, swaps and redeployment once the roster is published.

The roster cycle and deadlines

NHS England good practice

6 weeks

Rosters should be approved and published at least six weeks before they are worked; the guide says ideally 12 weeks for managers. Local policy sets your actual deadlines.

Requests open

Staff submit leave and other requests by the trust's cut-off. The guide's policy checklist says leave should be authorised in line with the e-rostering timetable, so booked before the roster is approved. Its audit tool asks whether at least three months of rosters are available for requests.

The roster is built

The roster creator builds it against the required staffing template, headroom and rules. High priority, hard-to-fill shifts should be filled first, per the checklist.

Two-level approval

The guide describes initial approval by the roster creator and final approval by an identified senior member of staff, after checking it is in budget, fair, safe and efficient.

Publication

The roster is published, ideally at least six weeks before the first shift. The audit tool asks whether six weeks of completed rosters are available for staff to review.

Live changes

Sickness, swaps and redeployment are recorded on the roster as they happen, so it reflects who is working.

Leave requests

The guide's section on staff non-working time sets out the good practice behind leave decisions:

✓ Headroom: a budgeted allowance to cover annual leave, sickness, study leave, non-clinical days and parenting. If lots of discretionary leave is not allowed for, the ward cannot meet service needs.
✓ Even distribution: annual leave should be spread evenly through the year so staffing stays sufficient and leave does not pile up at the end of the leave year.
✓ Limits in the system: the e-roster can hold a maximum or minimum number of staff on leave, and flags when too many or too few are booked.
✓ Set percentages: trusts with good practice often require a set share of leave to be taken at certain points, with the guide giving the example of 50 per cent by six months into the year.
✓ Peak periods: the policy checklist asks whether the policy sets out how annual leave requests for Christmas and New Year and key school holiday periods such as summer are handled.

For the entitlement itself see NHS annual leave entitlement explained and the annual leave calculator. To plan leave around bank holidays, try the bank holiday leave planner and the rota-aware NHS Leave Planner.

Shift and day-off requests

The guide asks trusts to enable mobile technology so staff can view their roster, request leave or book available bank duties in a timely manner, at least six weeks in advance, and says that wherever possible staff should use the mobile app or a web portal to make requests to the e-roster team. The policy checklist expects a section on how staff make requests, covering:

• a maximum number of days off within the e-roster period;
• requests considered in light of service needs;
• working restrictions and flexible working needs; and
• fairness in allocating shifts.

In practice this means a request is a preference, not a guarantee. A manager balances requests against the staffing the unit needs and the rules the system applies.

Fairness rules

The guide stresses that e-rosters should provide fair and transparent platforms across services, and that open and transparent e-rostering improves engagement and retention. The checks it describes include:

✓ Approval analysis that confirms the roster is in budget, fair, safe and efficient.
✓ Rules for rest periods and breaks. The checklist uses the example of an 11 hour rest period before the next shift, and asks that unpaid-break rules and time-owing processes are set out.
✓ A pre-approval checklist, including accurate leave and sickness hours and checking each person's net hours.
✓ Monthly reporting of measures such as headroom use, six-week approval rates, additional shifts and working restrictions to managers and the board.
✓ Working restrictions formally agreed and reviewed at least annually. The guide notes that lifting restrictions as needs change can make it easier to accommodate others.

Hours and rest rules also come from law and the contract: see our guides to the Working Time Regulations, rotation patterns and overtime. If a roster seems to break the rules, your union rep can help; see NHS staff representation.

Self-rostering

Traditional rostering

A roster creator builds the roster from the template, availability and requests, then it is approved and published. Staff influence it through requests.

Self-rostering

Staff enter their own preferred duties and days off, within rules set by the employer, and the manager reviews and approves the result. How much choice staff get, and the rules, are local.

The only NHS England description we verified is the Royal Free London case study: electronic self-rostering began in an ICU in January 2018 and expanded to 32 inpatient areas between September 2018 and May 2019. Staff had more flexibility and choice over their shifts, and the share of shifts requested by staff rose from about 4.3 per cent per four-week period to about 38 per cent by September 2019. The trust said managers and staff needed to understand their roles and responsibilities. That is one trust's result, not a national entitlement. We found no national self-rostering rulebook, so if you want it, ask your manager whether your area uses it and what the rules are.

Changes after publication

The guide says rosters are live systems that should reflect staff availability and deployment at all times, with changes and the reasons for them reviewed in monthly staffing meetings. The updates it lists include recording sickness, changes to shift start and end times, shifts swapped or redeployed from or to other areas, requests for temporary staffing, and requests for emergency leave. It also asks policies to keep shift changes to a minimum, and says extra shifts should have stated reasons and a stated approver. If you swap a shift, make sure it is recorded on the roster so your pay follows the right pattern: the guide says e-rostering supports paperless timesheets for unsocial hours and bank payments. See unsocial hours payments and bank holiday pay.

Doctors' rotas

Resident doctors' rotas have their own standards. NHS England's minimum standards for annual leave for resident doctors say that each department needs a clear, documented process for requesting leave, with a named contact; that leave is approved or declined in a timely fashion within the timeline in the policy; and that if leave is declined, the reason must be given at the time. They also say that swaps which facilitate leave, including into vacant shifts, must be considered, with a clear reason for any refusal, that there must be an appeals process, and that each organisation must have a process to ensure every doctor can take two consecutive weeks of leave in each 12-month period. Leave timescales themselves are left to each organisation's policy. Our guide on NHS doctors' pay and exception reporting cover other rota issues.

Systems and names

Trusts use different e-rostering products, commonly named HealthRoster, Optima and RosterPro, and suppliers rebrand and replace products, so the name on your trust's login page may differ from what colleagues elsewhere call it. The concepts above apply regardless. Menus, request types and cut-off dates are set by each trust, not the supplier. We deliberately do not describe individual screens because they vary and change. Your trust's rostering team or the e-rostering page on your intranet is the right place for a step-by-step guide.

ℹE-rostering and ESR are different

The NHS England guide says the Electronic Staff Record must be up to date for e-rostering to work. ESR is the national HR and payroll record; e-rostering is the local rota tool. Some employers book leave in ESR and some in the rostering system, so check which one is your record. See ESR self-service explained.

If a request is refused or ignored

• Ask for the reason and which rule it was based on (headroom, a limit on staff on leave, a peak-period rule).
• Read your trust's e-rostering and annual leave policies; they should align, per the guide.
• Ask whether there is an appeal route or an alternative date. Resident doctors have a minimum-standards appeals process.
• Raise a consistent pattern of unfairness with your manager, then HR, and use the grievance procedure if needed.
• Contact your union rep. If the issue affects your pay, see who to contact about wrong pay.

Frequently asked questions

How far ahead should my roster be published? +

NHS England and NHS Improvement's nursing and midwifery e-rostering good practice guide (updated September 2019) says e-rosters should be approved and published at least six weeks before they are worked, and tells ward and department managers that a minimum of six weeks, but ideally 12, is critical. It is good practice guidance rather than law, and your trust's own e-rostering policy is what applies to you. Ask your manager or e-rostering team what your trust's policy says.

Why was my annual leave request refused? +

E-rostering systems let managers set a maximum and minimum number of staff who can be on leave, and flag when too many or too few are booked, according to the NHS England guide. Leave is also managed within a budgeted allowance, called headroom, that covers annual leave, sickness, study leave and similar. A request can therefore be refused because the ward is already at its limit, not because of anything about you. Your trust's policy should say how requests are prioritised and whether a reason is given. If you are a resident doctor, NHS England's minimum standards say the reason for declining must be given at the time.

Do I have to book my leave before the roster is published? +

The guide's checklist for trust policies asks whether the policy ensures all leave is authorised in line with the e-rostering timetable, so it must be booked before the e-roster is approved. That is the model good practice describes, so many trusts set a cut-off. Late requests are possible in some places, but are usually treated as changes to a published roster. Check your trust's policy and the dates your roster team uses.

What is self-rostering? +

In the NHS England case study from the Royal Free London, electronic self-rostering gave staff more flexibility and choice over their shifts, starting in an intensive care unit in January 2018 and extending to 32 inpatient areas. The trust reported that the share of shifts staff requested rose from about 4.3 per cent to about 38 per cent in the ICU pilot by September 2019. We found no single national set of self-rostering rules, so how it works in your area is a local decision.

Can I swap shifts with a colleague? +

Often, but the rules are local. The NHS England guide says policies should cover the process for staff changing published e-rosters, including keeping the roster up to date and keeping shift changes to a minimum, and that swaps and redeployments should be recorded on the roster. Swaps still need to respect rest periods and your trust's rules, and a manager normally has to approve them. Ask how your team records swaps.

Is there a limit on how many days off I can request? +

The guide's policy checklist asks whether policies include a section on how staff make requests, with a maximum number of days off within the e-roster period, requests considered in light of service needs, working restrictions and flexible working needs, and fairness in allocating shifts. The actual maximum is a local figure, so look in your trust's e-rostering policy.

Do e-rosters affect my pay? +

Yes. The NHS England guide says e-rostering supports paperless timesheets, including unsocial hours and bank payments, by capturing data at source and signing it off for payment. The shifts and changes recorded on the roster can therefore flow into your pay. If your pay looks wrong after a swap or extra shift, check that it was recorded. See our guides on unsocial hours and wrong pay.

What if I have a flexible working arrangement? +

The guide describes working restrictions, also called flexible working, as arrangements that should be formally agreed between the ward, HR and the employee and reviewed at least annually in line with trust policy. They are built into the roster as restrictions. Our Flexible Working Request Pack and caring responsibilities guide help you make a request.
