Specialist Care for Hay Fever and Food Allergies
Understand your symptoms and explore your treatment options. Consultant-led allergy care for babies, children and adults, in London and by video across the UK.
How we can help
Choose the service that best matches your concerns. Your consultant will advise which assessment and tests are appropriate.
Still struggling with hay fever?
If sneezing, a blocked nose or itchy eyes affect your sleep or daily life, a specialist review can help clarify your triggers and treatment options.
Immunotherapy may reduce symptoms and medicine use in suitable patients. It requires a longer-term commitment, and results vary.
Worried about a food reaction?
We assess adults, babies and children with suspected or confirmed food allergies and provide personalised treatment and management recommendations.
For children who may benefit from further treatment assessment, we can arrange referral to a consultant paediatrician specialising in allergy, including discussion of oral immunotherapy where appropriate.

Your questions answered
Can I discuss hay fever immunotherapy at my first appointment?
Yes. Your consultant can review your symptoms, previous treatment and relevant test results to assess whether immunotherapy may be appropriate. Further testing may be needed before a decision.
Should I book a consultation or an allergy test?
If you are unsure which test you need, start with a consultation. Your history helps guide appropriate testing. Test results need to be interpreted alongside your symptoms; a positive test alone does not confirm a food allergy.
Can I have a video consultation?
Video appointments are available across the UK. Some assessments and tests require an in-person visit. The clinic can help you choose an appropriate appointment.
Do you assess children with food allergy concerns?
Yes. Please register your child and upload any relevant previous test results to the clinical portal. You can start with a video consultation or contact the clinic to arrange an appropriate in-person assessment. If skin prick testing is planned, please follow the clinic’s instructions about which antihistamines to pause and for how long.
If you suspect anaphylaxis, use your prescribed adrenaline treatment as instructed and call 999 immediately. This booking service is not for emergencies.
Consultant Expertise
The Same Consultants Who Lead NHS Tertiary Allergy Services
Our consultant allergists and immunologists hold substantive NHS posts at leading tertiary teaching hospital trusts, where they manage the most complex referred cases in the country. In private practice with UKallergy, patients benefit from that same specialist decision-making, without an NHS waiting list.
This depth of experience matters most in complex or ambiguous presentations — distinguishing true IgE-mediated and non-IgE-mediated food allergy from intolerance, unpicking multi-system reactions, or managing rare conditions such as hereditary angioedema and primary immunodeficiency.
Why This Matters for You
International Accreditation
First UK Clinic Accredited as Both a
UCARE & ACARE Centre of Excellence
UKallergy’s London Allergy & Immunology Centre has held both accreditations since November 2017, making it the first clinic in the United Kingdom to achieve UCARE accreditation followed by ACARE accreditation.
UCARE is a global accreditation programme run by GA²LEN (the Global Allergy and Asthma European Network), recognising specialist centres providing the highest standard of care for chronic urticaria (hives) and angioedema.
To achieve UCARE status, a centre must satisfy 32 stringent criteria assessed during a formal independent audit, covering clinical protocols, diagnostic standards, patient monitoring tools, research activity and education. Certification is renewed every 2–4 years.
ACARE is the companion accreditation to UCARE, also operating under the GA²LEN framework, recognising centres of excellence in diagnosing and managing angioedema — sudden deep swelling of the skin, lips, throat and digestive tract that can be life-threatening when the airway is involved.
Angioedema has multiple causes — allergic, hereditary (HAE), acquired and drug-induced — and requires highly specialist investigation to distinguish between them. ACARE accreditation confirms our centre meets the highest international standards for this complex condition.

Beyond Allergy
Specialist Support Beyond Allergy
Some symptoms need input from more than one specialty. Where appropriate, your allergy consultant can coordinate further assessment with colleagues in ENT, gastroenterology, endocrinology or neurology, helping you understand your symptoms and plan the next steps in your care.
ENT (Ear, Nose & Throat)
Chronic rhinosinusitis, nasal polyps, laryngeal symptoms and airway assessment relevant to severe allergic disease.
Gastroenterology
Eosinophilic oesophagitis, reflux, coeliac screening and complex gut symptoms that overlap with food allergy and intolerance.
Endocrinology
Thyroid and other hormonal contributors to chronic urticaria, and hormonal conditions that mimic or aggravate allergic symptoms.
Neurology
Assessment where neurological symptoms accompany or are mistaken for allergic or anaphylactic reactions.
Laboratory Standards
Every Sample Processed in Accredited Laboratories
Whether your sample is taken in clinic or sent to us in the post, it is processed by accredited laboratories using validated, quality-controlled methods. This means your results are directly comparable to NHS and international standards, and can be relied upon to guide safe treatment decisions — including immunotherapy and biologic prescribing.
✓Quality-controlled sample handling
✓NHS-comparable reporting standards
✓Secure UK-wide postal logistics

Advanced Diagnostics
ALEX³ Molecular Allergy Testing — 300 Allergens, One Blood Sample
Standard IgE blood tests measure your immune response to whole food extracts. Our ALEX³ component-resolved diagnostic (CRD) panel identifies IgE antibodies to the specific proteins within each allergen — the individual molecules that determine whether your reaction is likely to be mild or severe.
For example, sensitisation to the peanut protein Ara h 2 is associated with a risk of systemic anaphylaxis, while sensitisation to Ara h 8 (a birch pollen cross-reactive protein) typically indicates oral allergy syndrome. Without CRD, this crucial distinction is missed.
Every sample, whether taken in clinic on Harley Street or sent by post, is processed in an accredited laboratory, with results reviewed by your consultant via video.
What ALEX³ Identifies

Treatments
Allergen Immunotherapy — The Only Treatment That Changes the Underlying Allergy
Allergen immunotherapy (AIT) is the only treatment shown to modify the underlying immune response in IgE-mediated allergy — not just suppress symptoms. By gradually retraining the immune system to tolerate a specific allergen, it can provide lasting relief and, in some cases, sustained unresponsiveness (remission).
📋
Clinical evidence (BSACI BRIT Registry, 2025): Paediatric allergy services offering AIT are concentrated in urban centres, creating regional inequalities in access. Our nationwide postal testing kits and video consultations were designed precisely to bridge this gap for patients across the UK who cannot access specialist care locally.
Sublingual Immunotherapy (SLIT)
Daily drops or spray held under the tongue to desensitise to grass pollen, birch pollen, house dust mites, other tree pollens, moulds and animal dander. Safe and well tolerated, suitable for most age groups.
Food Allergy Assessment & Treatment Options
We help babies and children with suspected or confirmed food
allergies through specialist assessment, appropriate testing
and personalised treatment and management recommendations.
If you are interested in oral immunotherapy (OIT), we can
arrange referral to a consultant paediatrician specialising
in allergy to discuss whether this may be suitable for your
child and explore access to specialist treatment.
Your Patient Journey
From First Contact to Lasting Relief — Four Clear Steps
We believe a clear pathway reduces anxiety and improves outcomes. Here is what to expect when you come to UKallergy.
Register & Book Your Consultation
Create your patient account online in minutes, select the right specialist — allergy, immunology, dermatology, ENT, gastroenterology, endocrinology, neurology or paediatrics — and choose an in-person or video appointment. Same-day video appointments are available for urgent queries.
Comprehensive Allergy Assessment
Your consultant takes a detailed clinical history and recommends appropriate investigations. These may include skin prick testing, patch testing or specific IgE blood tests, including the ALEX³ panel where clinically indicated. Blood samples are processed by accredited laboratories. Where appropriate, your consultant can discuss supervised oral food or drug challenges and arrange these through a suitable hospital service, with a day-case admission for the procedure.
Clear Diagnosis & Personalised Treatment Plan
Your consultant explains results in plain language, distinguishing between true IgE-mediated allergy, intolerance and cross-reactivity. A written treatment plan is provided, including avoidance strategies, medication options and referral into our immunotherapy programme — or to a colleague in ENT, gastroenterology, endocrinology or neurology — where appropriate.
Ongoing Care, Immunotherapy & Global Support
Regular follow-up helps monitor your progress with immunotherapy and review your treatment plan. If you are travelling or relocating abroad, we can help explore options for continuing care through the Global Allergy Network. Please contact us in advance so that treatment availability and arrangements can be confirmed with the receiving clinic.

Patient Experiences
Trusted by Our Patients
Read genuine accounts from adults, children, and parents of babies who found clarity, confidence and lasting relief through our care.
Rated Excellent based on verified patient feedback
“After years of uncertainty, my consultation was a revelation. The detailed clinical history and ALEX testing provided clear answers to my contact allergies and identified a separate undiagnosed condition. I finally have a clear path forward.”
Complex Diagnosis
“Finding a specialist for our son’s multiple food allergies was incredibly difficult. The calm, educational approach gave us the answers we desperately needed after years of heartache. We cannot recommend the team highly enough.”
Paediatric & Multiple Allergies
“I was unable to visit London so used the postal ALEX test. The results were thorough and my video consultation with the consultant was just as informative as a face-to-face visit. Brilliant service for people outside of London.”

Common Questions
Frequently Asked Questions
What is the difference between a food allergy and a food intolerance?
Do I need a GP referral to be seen at UKallergy?
Can babies and very young children be tested for allergies?
What is the ALEX³ allergy test and is it better than a standard blood test?
Can my child be assessed for food oral immunotherapy?
We assess babies and children with suspected or confirmed
food allergies, arrange appropriate testing and provide
personalised treatment and management recommendations.
Oral immunotherapy (OIT) is not routinely provided through
our clinic. Where appropriate, we can arrange referral to
a consultant paediatrician specialising in allergy to
discuss your child’s suitability, available treatment
options and access to specialist services.
What happens if my symptoms are complex or involve more than one body system?
reflux and swallowing difficulty, unexplained hives with a possible
thyroid cause, or breathing symptoms that need an ENT opinion —
your consultant can draw on our wider multidisciplinary network,
including gastroenterology, endocrinology, ENT and neurology,
so you are not sent away to find a separate specialist yourself.
Will my health insurance cover allergy testing and treatment?
Many private health insurance policies cover allergy consultations
and diagnostic tests, including skin prick tests and specific IgE
blood tests. We recommend checking your cover with your insurer
before booking and obtaining any required pre-authorisation.
If you are insured with Aviva or Vitality, we kindly ask that you
pay for your appointment in advance. You can then submit your
invoice to your insurer for reimbursement, in line with your
policy terms.
For immunotherapy, payment is made directly to the clinic, as we
do not bill insurers for this treatment. If your policy includes
immunotherapy cover, you can arrange reimbursement directly with
your insurer. We recommend confirming this cover before placing
your treatment order.
We are happy to provide invoices and relevant clinical
documentation to support your claim. Reimbursement will depend
on your policy and your insurer’s approval.
