CRGH Egg Freezing Review

CRGH, the Centre for Reproductive and Genetic Health, recorded 536 egg storage cycles across 364 patients in 2023, the third-highest verified volume among London clinics that year (HFEA, 2026). It's one of ten clinics covered in our full London comparison guide, which ranks all ten by verified activity alongside cost and HFEA ratings.

The basics

CRGH was established in 1990 by Mr Paul Serhal, based on Great Portland Street, W1 (CRGH, n.d.-a). The clinic states it has helped more than 12,000 patients build or expand their families since opening, and has held its HFEA licence since 1992. It's one of the longer-running specialist fertility centres in London, with a particular public focus on complex cases.

What the HFEA says

• Inspection rating: 5/5, from an inspection dated 13 November 2018, the oldest inspection date among the clinics in this series (HFEA, n.d.).
• Licence status: Licensed until 31 March 2030 (HFEA, n.d.).
• Patient rating: 4/5, based on 34 ratings, the largest HFEA patient sample of any clinic in this series. Sixteen of the 34 respondents said costs matched what they expected going in, while 14 said costs ran higher than the initial quote (HFEA, n.d.).
• 2023 activity: 536 egg storage cycles across 364 patients (HFEA, 2026).

Its Google rating is 4.5/5 from 701 reviews, the largest review count of any clinic in this series by some distance, and broadly consistent with its HFEA patient rating.

How it compares in this series

CRGH ranks third by verified 2023 activity among the ten highest-volume London clinics in our comparison guide, and its Google rating, 4.5/5 from 701 reviews, is the largest and one of the highest review samples in the series, second only to London Women's Clinic's 287-review sample in absolute size but with a considerably better average score. Its HFEA patient-rating sample, 34 responses, is also the largest of any clinic covered in this series, giving both of its public rating figures unusually strong statistical grounding compared with clinics like IVI London or Guy's and St Thomas', where the HFEA sample sizes are in the single digits.

What it actually costs

CRGH publishes its "Secure" egg freezing package from £3,500, though the clinic is explicit that "treatment costs vary depending on your individual needs, particularly when it comes to medication," and provides an itemised quote after an initial consultation rather than a single fixed figure (CRGH, n.d.-b). Based on the clinic's own description, the package includes:

• An initial 60-minute consultant consultation
• Blood tests and investigations, including an ovarian reserve test
• A follow-up consultation to review results
• A nurse consultation covering medication and treatment steps
• Ovarian stimulation with monitoring scans and blood tests
• Egg collection under sedation
• Egg freezing by ultra-rapid vitrification
• Storage for up to 55 years, with consent renewal required every 10 years

That £3,500 headline is one of the lower starting prices among London's highest-volume clinics, and the itemised breakdown above is more transparent than most about exactly what a patient is paying for before medication is added. For how that fits into a realistic total cost across the market, see our full cost breakdown.

CRGH also offers PGT-A embryo genetic testing alongside its freezing packages, worth knowing about if that's something you may want to add later.

Track record and things to check

The clinic's largest HFEA patient sample in this series is also its most useful. Thirty-four responses is enough to draw more confidence from than the two-or-four-response samples some other clinics in this series carry, and the cost-expectation data point (16 of 34 found pricing matched expectations, 14 didn't) is a useful, specific signal to ask about directly during your own consultation.

The current inspection rating is from 2018. A 5/5 score from an inspection nearly eight years old carries less immediate weight than a recent one. Ask the clinic directly when its next inspection is due, and check the HFEA's own clinic-search tool for anything more recent by the time you're reading this.

As with any clinic, the broader academic literature on age-specific outcomes is worth keeping in view alongside any individual clinic's marketing: live birth rates after egg freezing vary substantially by the age at which eggs were frozen, independent of which clinic performed the procedure (Cil, Bang and Oktay, 2013). This applies as much to CRGH's own reported experience with complex cases as to any other clinic in this series; a clinic's willingness to take on difficult cases doesn't change the underlying biology of age and egg yield.

Questions worth asking this clinic specifically

• Has CRGH had a more recent HFEA inspection since the 2018 rating shown here, and if not, when is the next one due?
• Given that 14 of 34 rated patients said costs exceeded their initial quote, what does the itemised quote actually include, and what commonly gets added afterwards?
• What does the ovarian reserve test show, and how does that inform the recommended stimulation protocol and expected egg yield?
• If I later want PGT-A testing, how does that change the treatment plan and total cost?

Who this might suit

CRGH's itemised, relatively transparent pricing and large patient-rating sample may appeal to patients who want to understand exactly what they're paying for before committing. The clinic's stated focus on complex cases and PGT-A testing may also suit patients anticipating that they'll want genetic screening as part of a later cycle. Its Great Portland Street location also puts it within walking distance of several other clinics covered in this series, including Aria Fertility and the Lister site at The Portland Hospital, which can make comparison consultations more practical to arrange back to back. Given the age of the current inspection, it's worth checking for a more recent HFEA rating directly before booking.
