How to Ship from Ireland to UK: Best Rates and Services 2026

If you ship from Ireland to the UK regularly, you already know the main post-Brexit "surprise" is never the postage. It's the paperwork, the VAT rules, and the odd parcel that gets stuck because one tiny box on the customs form wasn't filled in right.

The good news is this: Ireland → UK shipping is still very doable, and for most small parcels it's not even that expensive. You just need to pick the right service for the right job, and get your customs flow tidy so you're not losing hours every week.

Let's walk through the actual rates, the services that make sense in 2026, and the customs bits you need to get right.

First: UK shipping isn't one thing anymore (NI vs Great Britain)

The biggest "Brexit gotcha" is that Northern Ireland and Great Britain are treated differently.

Northern Ireland (NI): for many everyday postal purposes, it's effectively treated like domestic. An Post says postal rates to Northern Ireland are the same as within the Republic.

Great Britain (GB): England, Scotland, Wales. This is where the post-Brexit customs rules kick in.

So when someone says "UK customer", you want their postcode and whether it's NI or GB before you pick a service or generate labels.

The 2026 reality: customs is the time thief, not delivery

An Post's own "big picture" delivery targets are still fairly reasonable:

• Standard international: 3-7 working days
• Registered: same broad lane as standard, just more secure
• Express / International Courier: 1-5 working days, with courier options offering very fast GB delivery

In practice, the things that slow GB deliveries down are usually:

• Missing/unclear customs description ("gift", "clothes", "parts" are classic delay magnets)
• Wrong value or currency confusion
• No HS (commodity) code when a carrier expects it
• VAT handling not clear (especially around the £135 threshold)

That's why the best "shipping hack" isn't a magical courier. It's having a repeatable customs workflow.

Know your package type: "packet" vs "parcel" matters (a lot)

An Post pricing is heavily driven by whether your item is a packet or a parcel.

From An Post's guide:

• A Packet is up to 2kg and within certain size limits.
• A Parcel can go up to 20kg and has bigger size limits.

This matters because lots of e-commerce orders (jewellery, tees, small skincare, phone cases) can stay in "packet" pricing if you don't overpack them.

If you're throwing a small item into a giant padded box "for protection", you're often paying for it twice.

Current An Post rates (Ireland → Great Britain) for 2026

These are from An Post's postal rates guide effective 27 February 2026, specifically the Zone 2 table for the UK (Great Britain).

A few common weights people actually ship:

Two quick observations (that save money immediately):

Standard parcels to GB are €21.00 up to 2kg. If you're sending a 1.2kg shoebox-sized order, you're likely sitting on that flat band.

If you can keep the item as a packet, you might be down at €9.90 (500g) or €13.00 (1kg).

That's why packaging choice is basically a pricing decision.

What about An Post International Courier Service (the fast one)

An Post also offers an International Courier Service (it's described as being in conjunction with DHL, available from selected post offices).

In the same 2026 rate table, you'll see "Int Courier (UK)" prices (again, Zone 2). For example:

• Up to 500g: €41.00
• 1kg: €42.50
• 2kg: €47.50

This is not the service you use for a €28 Etsy order. This is the "customer screaming, need it fast, tracked, reliable" option.

An Post's courier page also claims next day delivery to Great Britain for that courier lane (with day-certain language).

The courier comparison (An Post vs UPS/DHL/DPD etc.)

Here's the honest way I think about it as an Irish seller:

1) An Post Standard / Registered (best value for most small e-commerce)

If your parcel is not urgent, and it's not high value, Standard/Registered is usually the best blend of cost and sanity.

Use Registered when:

• it's a higher value item
• you want that extra security/compensation comfort
• you've had "it never arrived" claims before

An Post notes Registered includes insurance "up to €320" for Ireland/UK lanes.

2) Courier lanes (best for urgent / time-sensitive / high value)

If you sell something where late delivery causes refunds (fresh product, event outfits, last-minute gifts), you're paying for speed.

For courier shipments, carriers typically expect cleaner customs data. UPS, for example, explicitly highlights the need for a commercial invoice for shipments involving non-EU moves (which Ireland→GB effectively is from a customs perspective).

3) Contract couriers (best for volume)

DPD/UPS/DHL can be brilliant if you ship enough to earn a proper rate card. But the key is "enough". If you're shipping 5-10 UK orders a week, you can still do well, but you need to negotiate or use a platform that aggregates volume.

That's basically why tools like EirPost exist in the first place: you get the streamlined label flow and better pricing logic without having to become a shipping manager.

Post-Brexit customs requirements you actually need to care about

1) You'll need an EORI number if you export outside the EU

Revenue is very clear: if you move goods to/from countries outside the EU, you need to register for customs and get an EORI.

If you're a small business and you're thinking "sure I'm only sending a few parcels", don't ignore this. It's part of being set up properly.

2) Customs forms for An Post parcels (CN22 / CP72)

An Post states that when sending packets/parcels outside the EU, you need a customs declaration, typically:

• CN22 for most items
• CP72 for parcels or items valued over €300

3) Safety & Security declarations now matter more

This is the part people miss because it sounds "haulage-y", but it affects the ecosystem.

The UK government states that from 31 January 2026, goods imported from the EU to Great Britain must be covered by a safety and security declaration (ENS).

Irish Revenue also notes there's a legal requirement for an electronic export Safety & Security declaration in advance of export (often done as part of the export declaration, otherwise the carrier is responsible for an EXS).

Translation: carriers and postal operators want clean electronic data. The more you automate and standardise that data, the fewer "random" delays you get.

VAT to the UK: the £135 line you must understand

This one trips up Irish sellers constantly.

If you sell through a marketplace (Etsy, eBay, Amazon)

For goods sold through an online marketplace, the UK guidance says the marketplace is liable for VAT in certain situations, and the £135 limit applies to the total consignment value.

This is why Etsy orders often "just work" on the VAT side, as long as you enter the right values and the marketplace has collected VAT properly.

If you sell directly on your own website (Shopify/WooCommerce)

UK guidance for overseas goods sold direct says:

Consignments over £135: "normal VAT and customs rules" apply on import into Great Britain.

For under £135, the logic typically shifts toward VAT being handled at point of sale (depending on your setup), and that's where sellers either get it right… or customers get a "pay charges" message and you get an angry email.

I'm not giving legal advice here, but as a practical seller rule:

• Make the VAT handling obvious in your checkout and shipping info
• Keep your customs values accurate and consistent with the order

Delivery timeframes: what to promise customers (without making your life miserable)

If you want fewer "where's my parcel" emails, don't promise miracles.

A sensible promise for Ireland → Great Britain is:

• Standard: 3-7 working days (set expectations)
• Express / Courier: 1-5 working days, and courier lanes can be very fast

And then you add one honest sentence:

"Customs processing can occasionally add extra time."

Customers accept that. What they don't accept is silence.

Recommendations based on what you're shipping

If you're shipping light items (jewellery, tees, small skincare)

Try hard to stay in packet pricing.

Example:

A padded mailer with a bracelet, 250g, going to London.

• An Post Standard packet: €8.80
• Registered packet: €13.80

If your AOV is €35-€60, that's usually the sweet spot.

If you're shipping a "shoebox" order (hoodie, runners, bundle)

Assume you'll hit parcel pricing.

Example:

A 1.4kg box to Manchester.

• Standard parcel to GB: €21.00
• Registered parcel: €26.00

That €5 difference is often worth it for higher-value orders, especially if you're sick of the odd "never arrived" claim.

If the order is urgent or high value

Use courier.

Example:

A €220 handmade piece going to Edinburgh, customer wants it fast.

International Courier (UK) around €42.50-€47.50 depending on weight band

Courier lane is explicitly positioned as the quickest option, with very fast GB delivery messaging

Yes it's pricey. But it's cheaper than refunds, re-makes, and stress.

Real shipping scenarios (the kind you actually deal with)

Scenario 1: "Small Etsy order" to London

You sell a handmade keyring for €18, plus €4 shipping. It's 120g packed.

If you keep it as a packet, you're in that lower band.

Your win is packaging: slim mailer, tidy customs description ("Metal keyring"), correct value.

If you slap "Gift" and no detail, you're just inviting delays.

Customs form: CN22 is typically what you're doing here.

Scenario 2: "Shopify clothing order" to Birmingham (£110 value)

A jumper + beanie bundle. Total consignment is under £135.

This is where VAT handling matters. If you're selling direct, you need to be consistent with how VAT is handled and what's declared. Once it crosses £135, the "normal import VAT and customs rules" definitely apply.

Scenario 3: "B2B restock" to a UK retailer

If you're exporting as a business regularly, you should be thinking about:

• EORI setup
• Export declarations (Revenue points to electronic customs declarations through AES for exports)
• Cleaner commercial documentation (especially if you're using couriers)

This is where automation pays for itself quickly.

Where EirPost fits (and why it helps specifically with UK shipping)

UK shipping is exactly the lane where manual work multiplies.

One UK order is fine. Ten UK orders in a batch is where you lose an hour to:

• typing addresses
• copying order values
• filling customs details repeatedly
• printing labels one by one
• redoing the same HS/category decisions

EirPost is built for that reality. The point isn't just "cheaper labels". The point is:

• Bulk label creation (single + batch flows)
• Consistent customs data (fewer delays)
• Real-time price calculation so you can charge correctly at checkout
• Automatic PDF label generation and email delivery, so fulfilment stays smooth

If you're shipping to Great Britain weekly, you want the boring parts to stay boring.

The practical checklist (so you can implement this today)

Keep this simple:

• Split UK into NI vs GB in your shipping settings and address validation.
• Optimise packaging to stay "packet" where possible (under 2kg and within size rules).
• Use An Post Zone 2 rates as your baseline pricing model, not guesses.
• Standard for low risk, Registered for higher value, courier for urgent.
• Get your customs workflow consistent (CN22/CP72, accurate descriptions, correct values).
• Know the £135 VAT line so you don't surprise customers with charges.
• If you're doing this regularly, get EORI sorted and don't leave compliance as "future you's problem."

Bottom line

For most Irish businesses shipping to Great Britain in 2026:

• An Post Standard packet is the value king for light e-commerce.
• An Post Standard parcel (€21 up to 2kg) is a solid default for boxy orders.
• Registered is a small premium that often saves headaches.
• Courier is there when you need speed and certainty, not as your everyday option.

And your biggest improvement won't come from switching carriers. It'll come from tight packaging and clean customs data.
