For many UK mums, the return to work raises a practical question: how do you keep breastfeeding across a full working day without disrupting your schedule or your milk supply? The answer comes down to two things: knowing your legal rights and choosing a breast pump that fits your routine. Below, you will find both, along with a realistic pumping schedule built around typical UK working hours.
UK law gives breastfeeding employees real, enforceable protections. Understanding them before your first day back makes conversations with your employer far more straightforward.
The Equality Act 2010 (Amendment) Regulations 2023 makes it unlawful to treat a woman less favourably because she is breastfeeding. Since 1 January 2024, under the Equality Act 2010, less favourable treatment of a breastfeeding employee explicitly constitutes direct sex discrimination in a work context.
Under the Management of Health and Safety at Work Regulations 1999, your employer must carry out a risk assessment once you inform them in writing that you are breastfeeding. This assessment should cover your working conditions, break times, and access to a clean space for expressing.
The Workplace (Health, Safety and Welfare) Regulations 1992 separately requires employers to provide suitable rest facilities for breastfeeding women. Toilets do not count as a suitable space.
Your employer should provide a private room with a lockable door, a comfortable chair, access to an electrical socket, and a clean surface. Access to a fridge for storing expressed milk is also advisable and should form part of a thorough risk assessment. The space does not need to be a dedicated room; a meeting room or office that can be booked privately will work.
Write to your employer before you return from maternity leave. Outline that you plan to continue breastfeeding, that a risk assessment is required under the Management of Health and Safety at Work Regulations 1999, and that you will need a private space with fridge access and flexible break times. Putting this in writing creates a clear record and gives your employer time to make practical arrangements before your first day back.
Sample Letter: Notifying Your Employer of Your Breastfeeding Needs
[Your Name] | [Job Title] | [Date]
Dear [Manager's Name / HR],
I am returning to work on [date] and plan to continue breastfeeding. Under the Management of Health and Safety at Work Regulations 1999, I am formally notifying you that I am breastfeeding and requesting a risk assessment be carried out.
To support me during the working day, I would appreciate:
Please confirm in writing the outcome of the risk assessment and the arrangements in place before my return date. I am happy to discuss any practicalities with you.
Yours sincerely, [Your Name] | [Contact Details]
Many working mums use two pumps. This primary plus secondary strategy keeps your routine flexible and reduces the risk of disruption.
Your primary pump stays at home or in a fixed location. It delivers strong, consistent suction for your main expressing sessions, such as morning and evening.
Your secondary pump travels with you. It is lighter, more discreet, and designed for the commute, the office, or any time you need to express away from home.
This setup means you are never caught without a pump if one needs charging, cleaning, or replacing. It also means you can leave your primary pump ready at home, saving time on busy mornings.
Your primary pump needs reliable suction power, a comfortable fit, and parts that are quick to clean during a short lunch break.
Look for hospital-grade suction, multiple pumping modes, adjustable suction levels, and a closed-system design that keeps milk away from the motor, making the pump hygienic and easier to clean. Durability matters too, as this pump will be used several times a day.
Your primary pump is your home pump. It is the one you rely on for morning and evening sessions, and in the early weeks back at work, it plays a key role in establishing and protecting your milk supply.
Look for hospital-grade suction, multiple pumping modes, adjustable suction levels, and a closed-system design that keeps milk away from the motor, making the pump hygienic and easier to clean. Durability matters too, as this pump will be used several times a day. If you plan to use a wearable pump as your secondary option, a traditional motor-unit pump at home gives you stronger, more consistent suction for your main sessions.

A consistent schedule helps protect your milk supply. Most lactation professionals recommend pumping every two to three hours during a standard working day.
Start pumping at home before you leave for work to relieve fullness and get ahead on the day's supply. Aim for two to three expressing sessions during a typical eight-hour shift. Block out your diary in advance and let your manager or team know your planned times. Use your pump's timer or app to keep sessions to 15 to 20 minutes. If you feel full or uncomfortable before your next scheduled session, pump sooner rather than later to reduce the risk of blocked ducts.
| Time | Activity | Location |
| 6:30 AM | Breastfeed or pump at home | Home (primary pump) |
| 9:00 AM | Arrive at work | Office |
| 10:30 AM | First expressing session (15 to 20 min) | Private room at work (secondary pump) |
| 1:00 PM | Second expressing session during lunch (15 to 20 min) | Private room at work (secondary pump) |
| 3:30 PM | Third expressing session (15 to 20 min) | Private room at work (secondary pump) |
| 5:30 PM | Arrive home, breastfeed or pump | Home (primary pump) |
| 9:00 PM | Final pump or breastfeed before bed | Home (primary pump) |
Adjust these timings to match your shift pattern, your baby's feeding routine, and your own comfort.
Not automatically. UK law does not require employers to provide paid breaks specifically for expressing milk. However, refusing reasonable adjustments for a breastfeeding employee could amount to indirect sex discrimination under the Equality Act 2010. Many employers will accommodate flexible break arrangements once the legal framework is clearly set out, so it is worth raising this in writing before your return from maternity leave.
Place your milk in a sealed, labelled container inside an opaque bag or lunchbox. According to NHS guidelines, expressed breast milk can be stored in a fridge at 4°C or below for up to eight days. If you are not confident in the fridge temperature, use the milk within three days. An insulated bag with an ice pack is a practical alternative if you prefer not to use a shared fridge.
Yes. A discreet wireless breast pump like the Momcozy Air 1 Ultra-Slim Breast Pump fits entirely inside your bra and operates quietly. Wearing a loose top or scarf adds extra privacy. There is no law against expressing milk on public transport in the UK.
Rinse all non-electrical parts with warm soapy water immediately after use, then air-dry on a clean paper towel. For a deeper clean at home, sterilise parts by boiling them for five minutes. A small bottle of washing-up liquid and a compact bottle brush in your pump bag make office clean quick and straightforward.
A double pump expresses from both breasts simultaneously, cutting a 30-minute session to around 15 minutes. For mums with limited break time, a double pump is the more practical choice. A single pump works well as a lighter, more affordable secondary for occasional top-up sessions during the day.
A well-chosen primary and secondary pump, combined with a clear understanding of your workplace rights, gives you a reliable breastfeeding routine that fits around your job. A traditional double electric pump handles your home sessions, while a slim wearable secondary keeps you covered at the office and on the move. The Momcozy Air 1 Ultra-Slim Breast Pump, the Momcozy M5 Smart Wearable Breast Pump, and the Momcozy S12 Pro Quick Hands-Free Breast Pump each offer a different balance of discretion, app connectivity, and simplicity to match your working routine.
