IVI London Egg Freezing Review

IVI London, based at 83 Wimpole Street, recorded 342 egg storage cycles across 255 patients in 2023, a solid mid-table volume among London's highest-activity clinics (HFEA, 2026). It's part of the same IVI-RMA Global network as CREATE Fertility, also covered in this series, and one of ten clinics in our full London comparison guide.

The basics

IVI London has held its HFEA licence since 2016 and operates as part of IVI-RMA Global, a fertility group with locations across multiple countries and, by its own account, over 35 years of collective fertility expertise across the wider network (IVI, n.d.-a). The London site is in Marylebone's medical district, close to Oxford Street, in the same general cluster of specialist fertility clinics as several other clinics covered in this series.

What the HFEA says

• Inspection rating: 5/5, from an inspection dated 17 August 2022 (HFEA, n.d.).
• Licence status: Licensed until 27 November 2026 (HFEA, n.d.).
• Patient rating: 4/5, based on just four patient ratings, too small a sample to draw much confidence from (HFEA, n.d.).
• 2023 activity: 342 egg storage cycles across 255 patients (HFEA, 2026).

Its Google rating, from a much larger sample of 213 reviews, is 4.3/5, broadly in line with the HFEA patient rating but based on far more responses.

How it compares in this series

IVI London's four-response HFEA patient-rating sample is the smallest of any clinic covered in our comparison guide, tied only by the near-miss at Guy's and St Thomas' with two responses. Its £3,995 headline price sits roughly in the middle of the ten clinics, above Aria Fertility's £3,295 and CRGH's £3,500 but below CREATE Fertility's combined base-plus-support total. Its 342 egg storage cycles in 2023 place it fifth by verified activity among the ten clinics in the series, just behind CRGH and just ahead of its network sibling CREATE Fertility.

What it actually costs

IVI's published egg freezing package is £3,995 (IVI, n.d.-b). The clinic recommends budgeting a further £1,000 to £2,000 for investigations, additional blood tests and medication, which it states "can vary from patient to patient." Storage after the first year is £395 annually per sample type. IVI's own guidance is explicit that the £3,995 figure is a base price and that "you may be required to pay additional costs such as medication, fees and in-treatment blood tests," a caveat worth taking at face value when planning your own budget alongside our full cost breakdown across the UK market.

Track record and things to check

The HFEA patient-rating sample here is one of the smallest in this series. Four responses is not enough to treat as representative in either direction. The Google rating, drawn from 213 reviews, is a more statistically meaningful signal for this particular clinic, though it measures a different thing (unaudited public reviews rather than a structured regulator survey).

This is a satellite of a large international network rather than a standalone UK clinic. That can mean access to a wider base of research and shared clinical protocols across IVI-RMA Global's other sites, but it's worth asking specifically what, if anything, differs about the London site's own team, lab and outcomes compared with the network's marketing about itself as a whole.

The broader academic literature remains the most reliable outside reference point for any egg-freezing decision: live birth rates depend heavily on the age at which eggs are frozen, a factor that holds regardless of clinic (Cil, Bang and Oktay, 2013).

Being part of a large international network cuts both ways. It can mean access to shared research, standardised protocols and a wider base of clinical experience than a standalone clinic, but it can also mean a more corporate, less personalised feel to appointments, and less certainty about exactly who you'll see at each stage of your cycle. Neither is automatically better, but it's worth deciding which trade-off matters more to you before booking a consultation here, particularly if you've also considered independent, single-site clinics like Aria Fertility elsewhere in this series, where the ownership structure is very different.

Questions worth asking this clinic specifically

• What specifically differs about the London Wimpole Street site's own team, lab and outcomes compared with the wider IVI-RMA Global network's marketing?
• Given the very small HFEA patient sample, can I speak to recent patients or see more detailed, verified feedback for this specific site?
• What does the £1,000 to £2,000 additional estimate for investigations, blood tests and medication typically look like for someone my age and health profile?
• Is storage billed per sample type separately, and how does that affect the total annual cost if I freeze both eggs and, later, embryos?

Who this might suit

IVI London may suit patients drawn to the scale and international footprint of the IVI-RMA Global network, particularly those who value shared clinical protocols and research across a larger group rather than a single independent clinic. Its Marylebone location, close to several other clinics in this series, including Aria Fertility and Harley Street Fertility Clinic, may also appeal to patients planning several comparison consultations in one part of London. Given the very small HFEA patient sample, lean more on the larger Google review base and your own consultation experience than on the HFEA patient rating alone when weighing this clinic up, and ask specifically what, if anything, is unique to the London site rather than shared network-wide messaging.

It's also worth remembering that IVI London and CREATE Fertility, both covered in this series, sit under the same IVIRMA Global ownership. If you're considering both as genuinely independent options, it's worth asking each directly how much of their clinical team, lab and protocols are shared versus site-specific.
