Contraception methods available in our clinics

Intrauterine contraception (the coil)

Intrauterine contraception (‘the coil’) is a device inserted into the uterus (womb) to prevent pregnancy. There are two main types—the IUD (‘copper coil’) and the IUS (‘hormonal coil’). Both are very effective at preventing pregnancy and can last up to ten years, depending on what type of device you have fitted.

Contraceptive implant

The contraceptive implant is very effective and lasts up to 3 years. It is a plastic rod that releases progestogen, which is fitted into the upper part of your arm. The implant can be removed at any time and a new implant can be inserted at the same time if you wish to replace it.  

Contraceptive pill

The combined pill (‘the pill’) is taken every day, usually with a week off once a month (for a period).It contains two hormones which are very similar to the body's own hormones. Easy to start and stop, but can be difficult to remember to take it.

Contraceptive injection

The injection (or depo) is given as an injection into the bottom or thigh every three months. It contains a hormone called progestogen which is very similar to the body's own hormones. Long-lasting and convenient, it can stop periods temporarily.

Contraception patch

The patch is a square sticker like a thin plaster. 

This skin absorbs two hormones (oestrogen and progestogen) which are very similar to the body's own hormones. The patched is changed once a week.


There are two different types of condoms, condoms which are worn on the penis, and condoms which are worn inside the vagina. Condoms are made from a very thin latex, synthetic nitrile, polyisoprene or polyurethane, and can be used for vaginal, oral and anal sex. 

The size and fit of condoms on a penis is important so that they are comfortable and don't break or slip off. Condoms are the only option that prevents pregnancy and STIs.

Diaphragm  (Caya®) 

Diaphragms and cervical caps are cups made of silicone. 

It is put at the top of the vagina, to cover the cervix (neck of the womb). 

It's used with spermicide (a cream that kills sperm), and necessary to check it's in the right place before sex.

Emergency contraception

Emergency contraception can be used to help reduce the risk of pregnancy after unprotected sex, although it must be used within 5 days. The most effective method is the emergency IUD (copper coil).

If you have had unprotected sex and are not using a regular method of contraception, or if you have had a problem with your regular method (eg missed pill, broken condom), we would recommend you contact us to discuss emergency contraception. Please call the clinic on 020 8321 5718 or 020 8630 3295 for advice. 

If you are over the age of 16 and live in Brent, City of London, Ealing, Hackney, Hammersmith and Fulham, Harrow, Kensington and Chelsea, Lambeth, Southwark or Westminster, you can order free contraception via Sexual Health London.

Please note the Emergency Contraception Service via Sexual Health London (SHL) is not available for Hounslow residence however, please visit your local pharmacy or sexual health clinic.

Having an IUD/IUS fitted or replaced

If you are interested in having an IUD/IUS fitted, or need to have your device replaced, please watch the following video before booking an appointment:

When you come in for an IUD/IUS, you must not be at risk of pregnancy. This means:

  • Using a hormonal method of contraception (pill, patch, ring, injection or implant) until the day of your appointment, or
  • Abstaining from sex for at least 3 weeks before your appointment, or since the start of your last period 

If you already have an IUD or IUS and wish to replace it, you must ensure you avoid any unprotected sex in the 7 days prior to your appointment.

The majority of women can book directly into an IUD/IUS fitting appointment. We recommend having a pre-insertion appointment to discuss the procedure with a doctor or nurse if:

  • You are aged 17 or younger
  • You are aged 50 or older
  • You require a translator 
  • You have a history of problems with your uterus or ovaries (eg fibroids)
  • You have had a baby within the last 4 weeks 
  • You have recently had an abortion or miscarriage 
  • You have had a difficult or failed insertion of an IUD/IUS in the past 
  • You have not fully understood the information above and wish to discuss it with a doctor or nurse in person

Please note: We do not fit the Mirena IUS for the purposes of hormone replacement therapy (HRT) or for the treatment of gynaecological conditions (eg endometriosis), unless you also require the IUS for contraception. 

The clinics are staffed by both male and female clinicians—if you have a preference, please mention this when you call to book your appointment. 

To book an appointment, please call 020 8321 5718 or 020 8630 3295. We are unable to provide routine IUD/IUS insertion in the walk-in clinics, but you can attend to discuss the procedure with a doctor or nurse. 

Having an IUD/IUS removed 

If you wish to have an IUD or IUS removed and do not wish to have it replaced, please call the clinic to book an appointment or attend a walk-in clinic. To avoid any risk of pregnancy following removal, please ensure you do not have any unprotected sex in the 7 days before your appointment.

Unplanned pregnancy

If you are worried you may be pregnant, you should do a pregnancy test from the first day of your missed period or at least 21 days after you last had unprotected sex. 

If the result is positive and you wish to continue with the pregnancy, you should inform your GP as soon as possible.

If you do not wish to continue with the pregnancy, you can self-refer for an abortion from the following services:

If you are unsure, you can attend any of our clinics to discuss your options with a doctor, nurse or sexual health advisor. Please note that we do not provide abortion services within our clinics.
