UK AVEC and Ireland's Section 481 are the two credits incoming productions weigh against each other most often when shortlisting Scotland or Ireland. Both are well-administered. Both are routinely used by Apple, Netflix, Disney, Amazon, the BBC and the major studios. The question is rarely which is "better" in the abstract. It is which fits your script, schedule, locations and budget.
Short version. AVEC is a taxable expenditure credit, 34 percent gross on qualifying UK spend for film and HETV (≈25.5 percent net after CT), 39 percent gross for animation, children's TV and qualifying UK independent film under £15m (≈29.25 percent net), claimed through the CT600 after the accounting period. Section 481 is a refundable Irish corporation tax credit, 32 percent on eligible Irish spend, with up to 90 percent on commencement of principal photography. Different timing, different mechanics, different sweet spots.
The headline numbers, side by side
| UK: AVEC | Ireland: Section 481 | |
|---|---|---|
| Headline rate | 34 percent gross for film and HETV (≈25.5% net after CT). 39 percent gross for animation, children's TV and qualifying independent film under £15m (≈29.25% net). | 32 percent of eligible Irish expenditure, refundable. |
| Regional uplift | No general regional uplift. Devolved screen funds (Screen Scotland, Ffilm Cymru, NI Screen) operate alongside but separately. | Tapered uplift outside Dublin and Wicklow, set annually in Finance Acts. Effectively pushes total above 32 percent for qualifying regional shoots. |
| Qualifying formats | Feature film, HETV (≥30 min, £1m per broadcast hour), animation, children's TV, video games (separate VGEC). | Feature film, TV drama, animation, creative documentary. |
| Minimum spend | No fixed monetary minimum. HETV needs £1m per broadcast hour and 30+ min per episode. UK independent uplift caps at £15m total budget. | €125,000 eligible Irish spend; €250,000 total production cost. |
| Cap per project | No project cap. The 80 percent cap on qualifying UK spend applies (credit calculated on max 80% of core spend). | Credit capped at the lower of: eligible Irish spend, 80 percent of total cost, or €125m. |
| Cash mechanics | Claimed through CT600 after accounting period. Refund typically 4 to 8 months after period end. | Up to 90 percent on commencement of principal photography. Balance after compliance report. |
| Cultural test | BFI cultural test for British film/HETV. | Screen Ireland cultural certification. |
| Administration | HMRC, with BFI on cultural certification. | Revenue Commissioners, with Screen Ireland on cultural certification. |
| Cash-flow lending | UK specialist lenders advance against expected AVEC, typically at a wider discount than Section 481. | Irish banks and specialist lenders advance against the Section 481 certificate during prep and production. |
Reading the rate honestly
The headline numbers flatter the UK. AVEC is a taxable credit, so the 34 percent gross figure for film and HETV becomes roughly 25.5 percent after corporation tax at 25 percent. The 39 percent gross figure for animation, children's TV and qualifying independent film becomes around 29.25 percent net. Section 481's 32 percent is a refundable tax credit on eligible Irish spend, so the headline is closer to the cash you actually see. On most budgets Section 481 returns more cash per pound of in-country spend than AVEC at the standard rate.
That said, AVEC only applies to UK core expenditure and Section 481 only applies to Irish spend. The right comparison is total cash returned given where the production can credibly shoot. A drama that genuinely needs Edinburgh streets, Pinewood stages and a UK creative team leaves money on the table forcing an Irish structure on it. A coastal feature set in Connemara leaves money on the table basing in Cardiff.
Where AVEC genuinely pulls ahead
Studio capacity at scale. Pinewood, Leavesden, Shepperton, Elstree, Cardiff and Belfast between them clear stage capacity Ireland cannot match. If your show needs four contiguous 25,000 sq ft stages on a specific window with full lighting, grip and rigging inventory on-site, the answer is the UK. Scotland's stage build-out at FirstStage Leith, the Pyramids and Wardpark is real and the gap is closing for mid-scale projects, but at the top end the UK is the default.
The 39 percent gross uplift for animation, children's TV and qualifying UK independent film under £15m is genuinely competitive. Net cash returned after CT sits around 29.25 percent, close to Section 481's 32 percent, and the structuring overhead is often lower if the creative team is UK-based.
And HETV's lack of a per-hour cap is structurally useful at scale. A high-end series with £3m per broadcast hour clears AVEC on that full spend (subject to the 80 percent cap on qualifying core expenditure). Section 481 caps the credit at the lower of eligible Irish spend, 80 percent of total cost, or €125m, which on a single high-budget production hits ceilings sooner.
Where Section 481 genuinely pulls ahead
Cash-flow. 90 percent on commencement of principal photography is structurally faster than waiting for HMRC to refund AVEC after the accounting period closes. For productions where the prep and shoot cash cycle matters more than the headline rate, that timing difference is meaningful.
The regional uplift on the West coast of Ireland is real and routinely pushes the effective rate above 32 percent for productions that genuinely shoot in regional counties. There is no UK equivalent. Screen Scotland, Ffilm Cymru and NI Screen operate alongside AVEC but are separate funding streams, not uplifts on the credit itself.
And the lower entry threshold matters for mid-budget drama, documentary and animation. Section 481's €125,000 eligible Irish spend and €250,000 total production cost thresholds let projects use the credit at budgets where UK HETV (with its £1m per broadcast hour) and UK independent film (with its qualifying creative team tests) would not engage.
Studio capacity and crew depth, the real-world deciders
The UK clears roughly three million square feet of stage across the major hubs, plus recent build-out in Cardiff, Manchester and Belfast. Ireland clears closer to a million. For mid-scale projects Ireland competes well; at the top end the UK has the capacity Ireland does not.
Crew is comparable in skill and similar in price across the major departments. Ireland is tight on certain HoDs in heavy production seasons (March to October) because continuous streamer slate has bid up demand. The UK regional crew pools (Glasgow, Edinburgh, Cardiff, Manchester, Belfast) are similar in scale and price to Ireland's. London sits in its own bracket. Either way, plan crew attachments early.
Co-production: the underused third option
The UK and Ireland are both signatories to the European Convention on Cinematographic Co-production. A properly structured UK-Ireland co-production can access AVEC on the UK-spend portion and Section 481 on the Irish-spend portion. This is not a loophole or double-claiming on the same spend; it is a legitimate structure where the project genuinely splits production work across both jurisdictions, with separate Producer Companies on each side. For a £10m drama with a Belfast crew building stage work and a West of Ireland location block, the combined credit return materially exceeds running through one credit alone. The structuring needs proper legal and tax advice on both sides from the start, not retrofitted in post.
Picks by use case
Studio-based feature, 50,000+ sq ft stage need, London-based creative
Take UK AVEC. Ireland cannot match stage capacity at scale. Forcing the structure to Dublin to chase 32 percent rarely returns more cash than 25.5 percent net on UK spend when the build is already designed for Pinewood or Leavesden.
UK independent film, £9m budget, contemporary urban
Take UK AVEC at the 39 percent independent film uplift. Designed for exactly this bracket. Section 481 makes sense only if the script genuinely belongs in Ireland.
Animation feature, £8m budget
UK AVEC at 39 percent gross beats Section 481 in most scenarios. The animation uplift puts net cash returned roughly level with Ireland for any project where the animation team is genuinely UK-based.
HETV at £3m per broadcast hour
Take UK AVEC. The per-hour spend is well above Section 481's effective ceiling on a single production once the €125m and 80 percent cap interact. UK AVEC has no per-hour cap.
Coastal drama in Connemara, Kerry or West Cork
Take Section 481. The regional uplift was built for this. Atlantic seaboard cultural tests on Irish-set drama are straightforward. Cash-flow advantage matters when weather forces schedule shifts.
HETV drama at €1.2m per broadcast hour, location-flexible
Run both quotes. Both work at this bracket. Decide on real costed quotes from line producers in both jurisdictions and where the script genuinely belongs.
Creative documentary, €600k budget, mixed Ireland and UK locations
Take Section 481, structured through an Irish Producer Company. The low entry threshold favours documentary. AVEC's HETV thresholds rarely fit single docs.
The honest answer
The right credit is almost always the credit for the country where the project genuinely belongs. Where the script is genuinely flexible, run real costed quotes from line producers in both jurisdictions before deciding. Headline rates are an opening question, not a conclusion. And where the project genuinely splits both sides of the Irish Sea, an Ireland-UK co-production is the conversation worth having early, not late.
