Common Questions

Frequently Asked Questions

Everything you need to know before your first appointment.

Do I need a GP referral to book an appointment? +

No referral is needed for self-pay patients. You can book directly online or by phone. If you are using private medical insurance, check your policy as some insurers may require a GP letter.

How long do I have to wait for an appointment? +

Our typical waiting time is less than one week to see a consultant. We aim to offer flexible appointment times at our Harley Street, City or East London clinics.

How much does an allergy consultation cost? +

Consultation fees vary from approximately £300–£350 for self-pay patients. All consultants are registered with major private insurance companies. Allergy tests start from £84 per allergen. The remote ALEX molecular test or individual IgE tests online.

Can I get tested remotely without visiting the clinic? +

Yes. We offer the ALEX molecular IgE test as a home blood test anywhere in the UK. A self-collection kit is posted to you after payment. You collect a sample using the video tutorial and post it to our lab. Results are available within a week, interpreted by one of our consultants.

Should I stop antihistamines before a skin prick test? +

Yes — please stop antihistamines at least 48 hours before a skin prick test, unless your consultant advises otherwise. IgE blood tests are not affected by antihistamines.

Can children and babies be tested for allergies? +

Yes. Skin prick testing is safe from birth when clinically appropriate and is widely used in paediatric allergy care. We have specialist paediatric allergy consultants for children of all ages.

What is immunotherapy and is it right for me? +

Allergen immunotherapy (AIT) is the only treatment that addresses the underlying cause of allergy, not just symptoms. It is used for hay fever, allergic asthma and insect venom allergy. SLIT (sublingual) is now the first-choice method — daily drops or tablets taken at home for 3–5 years. Your consultant will advise after a full assessment.
