The honest version, from the Scotland end. I work both sides of the Irish Sea, and the answer changes depending on what you are actually shooting. Here is the head-to-head I run when a producer is genuinely weighing the two.

Short version. Scotland gives you compressed geographic variety in a single tour, the best-preserved medieval and renaissance built environment in the British Isles, and access to UK AVEC at 34 percent gross for film and HETV or 39 percent gross for animation, children's TV and qualifying independent film under £15m. Ireland has deeper continuous streamer slate, larger total studio capacity, and Section 481's faster cash mechanics. Pick by script and locations first, incentive second.

Side by side

Scotland vs Ireland for international production
Scotland Ireland
Tax credit UK AVEC: 34 percent gross (β‰ˆ25.5% net) for film and HETV. 39 percent gross (β‰ˆ29.25% net) for animation, children's TV and qualifying UK independent film under £15m. Claimed via CT600. Section 481: 32 percent refundable on eligible Irish spend. Regional uplift outside Dublin and Wicklow. Up to 90 percent on commencement of principal photography.
Heritage architecture Edinburgh Old Town, Stirling Castle, Linlithgow Palace, Culross, Eilean Donan, Dunnottar. Best-preserved medieval and renaissance built environment in the British Isles. Georgian Dublin terraces, Famine-era rural, Hiberno-Romanesque ecclesiastical, Big House country estates, Norman castles.
Geographic variety Highland plateau, sea lochs, volcanic peaks, Cairngorms, Skye, Glencoe, Caledonian forest, Borders. Edinburgh to Skye in 5 hours. Atlantic coast, Burren limestone, Wicklow uplands, Connemara, Aran Islands, Cliffs of Moher. More driving time between distinct landscape types.
Studio capacity FirstStage Leith, Pyramids Stirling, Wardpark Cumbernauld, BBC Studioworks Glasgow. Growing fast. Ardmore, Troy, Greystones, Ashford, Olympia. ~1m sq ft total, larger than Scotland.
Crew base Deep in commercials, music video and editorial. BECTU rates consistent. Drama bench growing with streamer slate. Large, supported by continuous slate from Apple, Disney, Netflix. Tight on HoDs in peak season.
Day rates Broadly comparable to Ireland at 2026 rates. Slightly lower than Dublin for commercials. Dublin slightly higher than Edinburgh in heavy season. Drama rates effectively converge.
Permit administration NatureScot, Historic Environment Scotland, 32 councils, private estates. Fragmented but each party is responsive. 2 to 6 weeks typical. Local authority film offices, OPW for heritage, NPWS for parks, Garda for road closures. Tighter coordination than Scotland.
Language and accent Scots, Scots English, Gaelic on the west coast. Wide accent range from Edinburgh RP to Glasgow. Hiberno-English, RP-flexible cast pool. Gaeltacht for Irish-language work.
Weather East coast (Edinburgh, Fife) meaningfully drier than the west. Highlands and west coast have faster weather turnover. May to early October optimal. Atlantic, mild winters, persistent low cloud, fewer extreme days. May to September best window.

Where Scotland actually pulls ahead

Heritage built environment is the clearest gap. Edinburgh Old Town is the best-preserved medieval urban environment in the British Isles, and Stirling, Culross, Linlithgow and Eilean Donan have no Irish equivalent at that scale. If your project needs hero medieval or renaissance secular architecture, Scotland is the answer and the rest of the comparison becomes academic. Ireland's strength is Georgian, ecclesiastical and country house, which is a different palette.

Compressed geography. Edinburgh to Glencoe in two and a half hours, to Skye in five, with volcanic peaks, sea lochs, Highland moor, Caledonian forest and coastal cliffs reachable on a single base-out tour. Ireland's western variety is real but spread over longer drives. For a location-touring piece that needs five distinct landscape types in two weeks, Scotland delivers more visual ground per shoot day.

UK AVEC's independent film and animation uplifts. The 39 percent gross rate for animation, children's TV and qualifying independent film under £15m puts net cash returned around 29.25 percent after CT, genuinely close to Section 481's headline 32 percent. For a UK-based animation team or a contemporary urban indie, the structuring overhead of forcing the project to Ireland often costs more than the gap in headline rate.

Where Ireland genuinely beats Scotland

Studio capacity at scale. Ireland's combined stage total (Ardmore, Troy, Greystones, Ashford, Olympia) is larger than Scotland's, and Irish stage availability is more predictable across the calendar. Scotland's stage build-out at FirstStage Leith, the Pyramids and Wardpark is real and the gap is closing, but if you need four contiguous 25,000 sq ft stages on a specific window, Ireland is more likely to deliver in 2026.

Continuous streamer slate has built Irish crew bench depth and rental house inventory in ways Scotland is still catching up on. Apple, Disney, Netflix and Amazon have been running shows in Dublin and Wicklow for a decade. That benefits any incoming production: more crew, more rental kit, deeper post-production options (Windmill Lane, Egg, Screen Scene).

Section 481's cash mechanics. 90 percent on commencement of principal photography is structurally faster than AVEC, which is claimed through the CT600 after the accounting period closes and typically refunds four to eight months later. For productions where cash-flow during prep and shoot matters more than the headline rate, that timing difference is meaningful.

Tax credits in more detail

UK AVEC. Audio-Visual Expenditure Credit replaced the legacy film and HETV reliefs. 34 percent gross expenditure credit on qualifying UK core spend for film and HETV, which works out at roughly 25.5 percent net after corporation tax at 25 percent. 39 percent gross for animation and children's TV (β‰ˆ29.25 percent net), and for qualifying UK independent film with a total budget under £15m and a creative team that meets the BFI Independent Film Tax Credit criteria. HETV requires at least 30 minutes per episode and core spend of £1m per broadcast hour. BFI cultural test required.

Section 481. Refundable Irish corporation tax credit, 32 percent on eligible Irish spend. Capped at the lower of eligible Irish spend, 80 percent of total cost, or €125m. Regional uplift outside Dublin and Wicklow set annually in Finance Acts. Up to 90 percent on commencement of principal photography under the current regime; balance after compliance report. Screen Ireland cultural certification required.

On most budgets, Section 481 returns more cash per unit of in-country spend than AVEC at the standard rate. For projects that qualify for the UK independent film or animation uplift, the gap closes meaningfully and the structuring overhead matters more than the rate.

Studio versus location

If your show is studio-heavy with a small location component, Ireland's larger stage total and more predictable availability gives it an edge in 2026. If your show is location-heavy, Scotland's compressed geography means a touring unit covers more visual ground per shoot day. The decision is rarely either/or, but the studio-versus-location balance in your shooting script will usually tilt the choice.

Crew, rates and the practical reality

2026 day rates are broadly comparable across major departments. Dublin runs slightly higher in heavy season (March to October) because continuous streamer slate has bid up the rate for top crew. Scotland is generally a touch lower for commercials and editorial. Drama rates effectively converge. Either way, plan crew attachments early. The HoD pool in both jurisdictions is meaningfully smaller than the London market, and the good ones book three to six months ahead in peak season.

Co-production: the cross-border play

Under the European Convention on Cinematographic Co-production, a UK-Ireland co-production can claim AVEC on UK spend and Section 481 on Irish spend, with separate Producer Companies on each side. For projects whose narrative or production naturally splits between a Scottish location block and an Irish studio block, or vice versa, the combined credit return materially exceeds running through one credit alone. Two Producer Companies, clean spend separation, proper legal and tax structuring from the start.

Picks by use case

Medieval, renaissance or Georgian Scottish period drama

Take Scotland. Edinburgh Old Town, Stirling, Culross. Ireland cannot match the preserved built environment at that scale.

Location-touring piece needing 5+ distinct landscape types in two weeks

Take Scotland. Volcanic peaks, sea lochs, moor, Caledonian forest, coastal cliffs all reachable on a single base-out tour. Ireland's geography is more spread out.

UK independent film, £9m budget, contemporary urban

Take Scotland (UK AVEC at 39 percent gross independent film uplift). The structuring overhead of running through Ireland rarely returns more cash than 29.25 percent net on a UK-set script.

Animation feature, £8m budget

Take Scotland (UK AVEC at 39 percent gross). The animation uplift puts net cash returned close to Section 481, and the structuring is simpler if the animation team is UK-based.

Coastal drama set on the Atlantic seaboard

Take Ireland. Connemara, Donegal, Kerry and West Cork are written for this. Section 481 with regional uplift returns more cash than UK AVEC on Highland equivalents, and the Wild Atlantic Way is a specific look Scotland's west coast does not replicate exactly.

Studio-led drama, 50,000+ sq ft stage need

Take Ireland. Larger stage total and more predictable availability in 2026. Scotland's stage build-out is real but still catching up at scale.

HETV drama at £1.2m per broadcast hour, location-flexible

Run both quotes. AVEC HETV is uncapped on per-hour spend. Section 481 returns more cash per unit of Irish spend. Decide on real costed quotes from line producers in both jurisdictions plus where the script genuinely belongs.

The honest answer

Where the script genuinely belongs is the right answer almost every time. If the brief calls for Highland geography, medieval Scottish heritage, or qualifies for the UK independent film or animation uplift, Scotland is the call. If the brief calls for Atlantic coast settings, large contiguous stage capacity, or fast cash-flow against the credit, Ireland is the call. Where the script is genuinely flexible, run real costed quotes from line producers in both jurisdictions and let the numbers decide. Headline incentive rates are an opening question, not a conclusion.
