TL;DR: Sound design for video production in the UK costs between £1,500 and £20,000+ depending on the scope — dialogue editing alone sits at the lower end, while a full Dolby Atmos theatrical mix for a feature-length project sits at the top. Most corporate films and brand content fall in the £2,000–£6,000 range for a complete post-production audio package.
What Is Sound Design?
Sound design is the craft of building, editing, and mixing the entire audio layer of a film, documentary, or brand video. It encompasses 3 distinct disciplines that are often quoted separately: dialogue editing (cleaning and syncing recorded speech), sound effects and SFX design (creating or sourcing every non-music audio element), and the final mix (blending all elements into a coherent, broadcast-compliant stereo or surround master). Skimping on sound design is the most common way to undermine an otherwise well-shot video — viewers will tolerate slightly imperfect visuals far longer than they'll tolerate audio that crackles, drops, or feels mismatched with the image.
What Drives the Price?
- Scope of work: Dialogue edit only vs. dialogue + SFX + music integration + final mix are very different scopes.
- Delivery format: A stereo web master is far cheaper to produce than a 5.1 or Dolby Atmos theatrical mix.
- Project length: Minutes of finished content scale cost directly — a 2-minute brand film vs. a 90-minute documentary is a 45× difference in runtime.
- Original SFX creation: Bespoke SFX design (foley recording, custom synthesis) is billed separately to library sourcing.
- Location audio quality: Poorly recorded dialogue that requires heavy noise reduction or ADR (automated dialogue replacement) adds significant time and cost.
- Music stem integration: Composited multi-stem music tracks take longer to mix and master than a single stereo bed.
- Deliverable count: Each version (broadcast, social square, vertical, audio description) adds mix time.

Vendor Tiers: Freelancer vs. Boutique Studio vs. Post-House
At the freelance tier, a sound designer or re-recording mixer working from a treated home studio will charge day rates of £350–£600. They handle dialogue editing, library SFX, and stereo mixes competently and are the right choice for most branded content and short-form documentary work. Expect a 2-minute brand film to take 1–2 days.
Boutique post-audio studios (typically 3–10 staff in London or Manchester) charge £600–£1,200 per day. They offer Pro Tools HDX or Avid S6 mixing consoles, proper acoustic treatment, and the ability to run ADR sessions on-site. For broadcast deliverables and multi-platform campaigns, they offer the QC chain required by major broadcasters.
Major Soho post-houses (Dolby Premier and Atmos-certified facilities) charge £1,200–£2,500+ per day, with theatrical Atmos sessions commanding premium rates. These facilities are appropriate for Netflix, Amazon, or theatrical releases. For a standard 30-second TV commercial, expect the mix to run £3,000–£6,000 at this tier.
Dolby Atmos: What It Adds
Dolby Atmos is an object-based audio format in which individual sounds are positioned in 3D space rather than assigned to fixed speaker channels. For streaming platforms, Apple TV+ mandates Atmos for original content; Netflix strongly prefers it for premium titles. An Atmos mix requires a Dolby Premier or Dolby Atmos Production Suite-certified facility, specialist mixing hardware, and a final mastering pass to create the Audio Definition Model (ADM) master file. Budget a minimum uplift of £3,000–£8,000 on top of a standard 5.1 mix for an Atmos deliverable, depending on project length and complexity. For a 30-minute documentary, a full Atmos package typically runs £6,000–£12,000.
When to Pay More
- Your project is going to broadcast or a streaming platform — the technical delivery spec (loudness normalisation at -23 LUFS for EBU R128, -24 LUFS for ATSC A/85) requires a metered mix, not a creative guess.
- You have poorly recorded dialogue that needs noise reduction, de-reverberation, or ADR replacement — this is intensive work and hourly rates climb fast.
- Your brand relies on a signature sound identity (audio logo, recurring sonic motif) — this requires a sound designer, not just a mixer.
- The film involves complex SFX sequences — action, natural environment, product demo — where bespoke sound will significantly elevate production value.
- You need multiple deliverable mixes: broadcast, social, theatrical, and M+E (music and effects only for international dubbing).
Red Flags When Hiring
- No loudness specification on the quote: Any professional sound for video quote should specify the target loudness standard (EBU R128, ATSC A/85, or -14 LUFS for streaming).
- No mention of revision rounds: Mixing always requires client feedback. If revisions aren't scoped, budget overruns are near-certain.
- Bundled "sound design" with no breakdown: Insist on seeing dialogue, SFX, and mix billed separately so you can understand where cost lies and what's being delivered.
- No ADR capability for a dialogue-heavy project: If your location audio is a known risk, confirm the studio can run ADR sessions before booking.
- Quotes per minute without project context: Per-minute pricing applied to complex projects routinely underestimates cost. A flat project or day-rate is more reliable for anything over 5 minutes.
Frequently Asked Questions
-
Does sound design include music?
Usually not. Sound design covers dialogue, SFX, and the mix. Music — whether licensed or commissioned — is a separate budget line. The sound designer will integrate your music stems into the mix, but sourcing or composing music is outside their scope unless explicitly agreed. -
What is loudness normalisation and why does it matter?
Streaming platforms and broadcasters normalise audio to a standard loudness level (typically -23 LUFS for broadcast, -14 LUFS for streaming). If your mix is delivered too loud or too quiet, the platform will apply automatic gain adjustment that can make your audio sound distorted or thin. A proper mix delivered to spec avoids this. -
What's ADR and when do I need it?
ADR (Automated Dialogue Replacement, also called dubbing or looping) is the process of re-recording dialogue in a studio to replace unusable location audio. It's needed when wind noise, traffic, or set noise has destroyed the original take. ADR sessions typically cost £400–£800 for a half-day session plus the actor's re-booking fee. -
How long does a sound mix take?
A 2-minute brand film takes 4–8 hours including SFX and mix. A 30-minute documentary typically takes 2–4 days. A 90-minute feature with full design can take 15–30 days depending on complexity. -
What's an M+E track and do I need one?
An M+E (Music and Effects) track contains everything except dialogue — it's used by international distributors to replace the original language dialogue with a dub. If you anticipate international sales or distribution, request an M+E master at the time of the original mix; it's far cheaper to create it then than to reconstruct it later. -
Is Dolby Atmos worth it for a brand video?
For web and social, no — stereo is the standard. For cinema advertising, streaming-platform originals, or high-production-value brand experiences shown at events or in showrooms, Atmos adds genuine impact and is increasingly expected by premium clients. -
What files do I need to supply a sound designer?
A locked picture edit (H.264 reference and/or ProRes), all original location audio files (BWF/WAV), any music stems or licensed tracks, and a list of all deliverable specs including platform, loudness target, and aspect ratios. -
How many revision rounds are included in a standard package?
Two revision rounds is the professional standard — a client review pass after the first mix and one round of amends before final delivery. Additional revisions are typically charged at £80–£200/hour.
