The short answer

A chalazion can be removed on the NHS, but for most people it will not be. NHS funding for chalazion surgery is restricted almost everywhere in England, and the restrictions are written down: the lump has to have lasted a certain length of time, resisted proper conservative treatment, and be causing a defined problem before an operation is funded.

If your chalazion is simply there, visible and irritating, that usually will not qualify. That is the reason most people who have one removed in London pay for it privately.

What the NHS actually requires

Individual NHS commissioning policies are set by Integrated Care Boards, so the wording differs slightly by area — but the shape is consistent. The policy from NHS Bath and North East Somerset, Swindon and Wiltshire ICB (document BSW-ICB-CP034, version 3, review June 2024) is typical, and it is unusually clear:

“This procedure is not normally funded in secondary care.”

It then sets out the criteria, and the word between them is AND, not “or”. All of them have to be true. The chalazion must:

• have “been present for more than 6 months verified in clinical notes”
• have “been managed conservatively with heat, lid cleaning and massage for 4 weeks”
• be “present on the upper eyelid and interferes significantly with vision”
• be “a source of regular infection that has required medical attention twice or more within a six-month period”

The same policy adds one route that bypasses all of it: “BSW ICB will fund removal where malignancy is suspected.” If there is any question that the lump might not be a chalazion, the funding position changes completely — and that is the right way round.

Policies in other areas, including Hertfordshire and West Essex, Cheshire and Merseyside and Vale of York, take the same approach under the heading “procedures not routinely commissioned”. Check your own ICB’s policy rather than assuming; the criteria above are an example, not a national rule.

Why most people do not meet it

Read the four criteria again as a set. A chalazion has to be six months old, properly treated at home for a month, on the upper lid, blocking vision, and repeatedly infected. Most chalazia are none of those things — they are on the lower lid, or they are painless, or they are simply visible in every photograph.

That is not an oversight in the policy. It reflects the natural history of the condition, which Moorfields Eye Hospital states plainly:

“Chalazia will often disappear without further treatment within a few months and virtually all will re-absorb within two years.”

From a commissioning point of view, a lump that resolves on its own is not an operation worth funding. From the point of view of somebody two months into it, with a hard lump on their eyelid and a wedding in three weeks, “virtually all within two years” is a very different sentence.

Both things are true at once. Deciding between them is what this page is for.

Waiting, and what happens while you wait

Before anything else, give conservative treatment a fair attempt — not because a policy asks for it, but because it works often enough to be worth a month of your time. Warm compresses held against the closed lid for five to ten minutes, two to four times a day, with gentle massage towards the lid margin afterwards, and lid hygiene to keep the gland openings clear. Our guide to eyelid cyst home remedies sets out what helps and what does not.

If you are going down the NHS route, the sequence is: GP first, conservative management documented, then a referral that has to satisfy the criteria above. Where a service exists, that referral may go to a GP with Extended Role rather than to a hospital eye department. Waiting times depend on your area and on which stage you are at, and we cannot quote a figure that would be true across London — ask your GP practice what the current local wait is at the point of referral.

What matters more than the wait is what you do during it. A chalazion that is left alone and kept clean is not getting more dangerous. A chalazion that is squeezed, picked, or treated with something bought online can become an infected one.

What going private involves

Privately, the sequence is shorter: no GP referral is needed, and assessment and treatment can usually happen in the same visit.

Pregnancy does not rule the private route out either — see chalazion removal during pregnancy.

The operation is incision and drainage. Anaesthetic eye drops numb the surface first — a brief sting of about ten seconds — then a small amount of local anaesthetic is injected into the eyelid. The incision is made on the inside surface of the lid, so the gland is cleared without a scar on the outside, and no stitches are needed. Afterwards, chloramphenicol ointment and a soft eye pad, which you take off yourself after 24 hours.

Bruising peaks at about 48 hours and settles over roughly five days, which is also when most people are back at work and driving. Contact lenses and eye make-up wait two weeks, until the surface inside the lid has fully healed. Around one chalazion in ten comes back and needs a second procedure.

At London Skin Clinic the fee is £600 after a £100 consultation, and it is the same £600 if a second chalazion on another lid is treated in the same session — it is a more complex procedure rather than a discounted add-on. Full detail is on our eyelid cyst removal page, and the procedure itself is covered in our chalazion removal guide.

Which route makes sense for you

There is no wrong answer in the middle rows. There is a wrong answer in the last one, which is waiting.

Your questions, answered

Can I get a chalazion removed on the NHS?

Sometimes, but the criteria are strict. Most ICB policies list chalazion removal under “procedures not routinely commissioned” and require the lump to have lasted more than six months, to have been treated conservatively for four weeks, to sit on the upper lid and interfere with vision, and to have been repeatedly infected — all of them, not one. Removal is funded without those hurdles where cancer is suspected.

Does the NHS treat chalazion removal as cosmetic?

Not in name, but in effect. The policies fund removal when the lump causes a functional problem — obstructed vision or repeated infection — and not when the objection to it is how it looks. A visible, painless chalazion on the lower lid is exactly the case that falls outside funding.

Do I need a GP referral to have it removed privately?

No. You can book a consultation directly. A referral letter is welcome if you have one, but it is not a requirement.

How long should I wait before treating it?

Give warm compresses, massage and lid hygiene a consistent four weeks before deciding anything. Moorfields notes that chalazia often disappear within a few months and that virtually all re-absorb within two years — so time genuinely is a treatment. Whether you want to give it that long is a separate question, and a reasonable one.

Can my GP just drain it?

A GP may lance a stye, which is a different, infected lump. A chalazion is a blocked oil gland with firm contents, and clearing it properly means incision and curettage of the gland rather than releasing pus. Some areas commission GPs with Extended Role to do exactly this; most do not.

If I pay privately and it comes back, do I pay again?

Around one in ten chalazia recur and need a second procedure. Ask at your consultation how recurrence is handled before you book — it is a fair question and the answer should be given to you in writing.
