Summary
Home cinema is the AV job that separates a genuine specialist installer from someone who can mount a TV and plug in a soundbar. The equipment budget is only ever part of the story — a customer who spends £15,000 on speakers and a projector in an untreated room with poor light control will be disappointed, and will (fairly) blame the installer, not the acoustics. Pricing this work correctly means pricing three things separately: the AV equipment and installation labour, the room engineering (acoustic treatment, light control, structural work), and the supporting infrastructure (dedicated electrical circuit, structured cabling, networking).
The single biggest pricing mistake is quoting "supply and fit" for the electronics without pricing the room. A projector and screen dropped into a bright, reflective, untreated living room will never perform to spec regardless of how good the kit is — and a customer who later commissions the room properly will remember that the first quote didn't mention it. Conversely, quoting full acoustic treatment for a customer who only wants a big TV and a soundbar in the corner of the lounge is over-specifying and will lose the job to a competitor's more realistic quote.
This guide breaks the job into three realistic tiers — living-room AV upgrade, mid-tier dedicated room, and premium dedicated cinema — with labour and materials cost bands for each, plus the electrical, structural and acoustic line items that must be priced in. For the underlying design specification (room dimensions, speaker layouts, viewing distances) see home cinema room design.

Regional variation: London and the South East run 25–35% higher than the rest of the UK for CEDIA-registered AV integrators, driven by day rates and the concentration of premium-tier work in that market. Outside London, mid-tier and premium installers typically operate at 15–20% below London day rates; rural and remote sites should factor in mileage/overnight costs for multi-day premium builds.
Detailed Guidance
Structuring the quote into three components
Present the quote as three distinct blocks, even for a single fixed-price job — this is standard practice among CEDIA-registered integrators and it protects both parties when scope changes mid-project (which happens often once a customer sees the projector image on a properly treated wall for the first time).
- AV equipment and installation — display/projector, AVR or amp separates, speakers, cabling, calibration.
- Room engineering — acoustic treatment (absorption, diffusion, bass trapping), light control (blackout blind/curtain, matt dark wall/ceiling finish), acoustic door if budget allows.
- Infrastructure — dedicated electrical circuit(s), structured cabling (CAT6a for control and networking, HDMI/HDBaseT for signal distribution over distance), lighting/blind control integration.
A customer asking "why is your quote three times the price of the online AV package deal?" needs this breakdown — the online package is component 1 only, assumes the customer's existing (uncontrolled, unshielded, likely single-socket) electrical supply, and includes zero room engineering.
Electrical infrastructure — the part most often under-priced
- Dedicated circuit for the AV rack — a 16A radial circuit run directly from the consumer unit, sized for the amplifier/AVR/power conditioning load, keeps the AV system isolated from noise and load-switching transients on general household circuits. This is standard practice on mid-tier and premium builds; see smart home consumer unit considerations for consumer-unit sizing guidance where an AV rack is one of several dedicated circuits being added.
- Projector supply — a ceiling-mounted projector generally needs its own switched fused connection point above the ceiling void, not a trailing extension lead — factor in first-fix cable routing before any ceiling boarding or plastering.
- Notification — any new circuit from the consumer unit, or consumer unit alteration, is notifiable under Part P; use a competent persons scheme electrician (NICEIC/NAPIT) to self-certify. See part p overview for the full notifiable-work list.
- RCD protection — standard domestic RCD/RCBO protection applies to AV circuits the same as any other final circuit; no special exemption exists for AV equipment.
Acoustic treatment — why it can't be skipped on dedicated rooms
Acoustic treatment is the line item customers most often want to cut, and the one that most determines whether the finished room actually sounds like the demo they heard in a showroom.
- RT60 (reverberation time) target — 0.3–0.4 seconds for a residential dedicated cinema room, tighter (around 0.2s) for a dialogue-focused screening room. Untreated stud-and-plasterboard rooms typically sit well above this, producing boomy, unclear dialogue regardless of speaker quality.
- Bass trapping — corner-mounted absorbers are essential below roughly 250Hz; without them, low-frequency modal buildup causes uneven bass response room to room, a problem no amount of subwoofer calibration can fully correct.
- First-reflection points — absorption panels at the side-wall and ceiling points where sound first reflects back to the listening position materially improve clarity; this is a targeted, not blanket, treatment approach.
- Diffusion — on rear walls, scatters rather than absorbs sound, preserving a sense of space without deadening the room.
Price acoustic treatment as its own line item with a clear before/after explanation — most customers have never heard the difference and won't value it until they understand what it fixes.
Light control and room finish
- Blackout requirement — for projector-based setups, full light exclusion (blackout blind, lined curtain, or no external windows) is close to mandatory for daytime viewing; a bright ambient room can wash out contrast on even a high-lumen projector.
- Wall/ceiling finish — matt black or dark grey finish on walls and ceiling reduces stray light bounce and improves perceived contrast; this is a decorating cost, not an AV cost, but must be scoped and priced with the customer upfront.
- TV-based rooms — light control matters far less; OLED and modern LED panels tolerate ambient light well, which is one reason a TV-based living-room install is cheaper to deliver to a satisfying standard than a projector-based one.
Networking and control cabling
- Structured cabling — CAT6a runs from a central patch location to the AV rack, wall plates, and any network-connected control points; always first-fix before plastering closes the walls. See home networking for av for switch and access-point specification.
- Signal distribution — HDBaseT extends HDMI signal over CAT6a for runs beyond the ~5–10m practical limit of standard HDMI cable, relevant where the AV rack sits in a different room (a common design choice to keep fan noise and heat out of the cinema room itself).
- Multiroom audio integration — where the cinema system shares infrastructure with a wider multiroom audio install, price the shared cabling and network backbone once, not twice; see multiroom audio installation.
Common site overruns to price in
- Existing wiring inadequate for the AV rack load — older properties often have no spare capacity on the consumer unit; a board upgrade may be needed before the dedicated circuit can be added.
- Structural work for acoustic door or wall build-out — dedicated rooms sometimes need a stud wall rebuild to accommodate acoustic lining; this is a carpentry/plastering cost that must be scoped on survey, not assumed.
- Ceiling access for in-ceiling Atmos speakers or projector mount — joist positions rarely align conveniently with the ideal speaker/projector locations; allow contingency time for noggin fitting.
- HDMI/HDCP compatibility issues on long cable runs — a run that tests fine on the bench can fail once buried in a wall cavity with other cabling nearby; always test signal integrity after first-fix, before final decoration closes access.
- Customer scope creep once the room is treated — very common once a customer hears the acoustic difference; have a clear change-order process rather than absorbing upgrades into the original fixed price.
Frequently Asked Questions
Do I need planning permission or Building Regulations approval for a home cinema room?
Not normally, if the work is internal (converting an existing room) and doesn't involve structural alterations, extensions, or a change of use. Building Regulations do apply to any new electrical circuit (Part P notification) and to any structural work such as removing a wall or altering a loft/basement space to create the room — treat those elements as separate notifiable/approval items within the wider project, not as part of the AV scope.
Is a projector or a large TV cheaper to install overall?
A large TV setup is almost always cheaper once room engineering is included, because it avoids the light-control and acoustic-treatment costs that a projector-based dedicated room typically requires to perform well. A projector delivers a genuinely bigger, more cinematic image at a given budget, but only once the room is treated — factor the full room cost into the comparison, not just the display hardware price, when advising a customer.
How long does a premium dedicated cinema room installation take?
A premium 7.1.4 build with full acoustic engineering, structural work, and lighting/blind integration typically runs 10–20 working days across multiple trades (electrician, acoustic installer, AV integrator, decorator), not counting any structural build-out. This is usually phased: first-fix electrical and cabling before plastering, acoustic treatment and room finish, then AV installation, calibration and commissioning last.
What ongoing costs should I mention to the customer?
Projector lamp/laser life (3,000–20,000 hours depending on technology) is the main recurring cost on projector-based systems — budget £150–£500 for lamp replacement where applicable, though laser-light-source projectors avoid this. Beyond that, a home cinema system has no meaningful running cost beyond electricity, but a calibration/service visit every 1–2 years is worth quoting as an optional maintenance package on premium builds — see smart home commissioning handover for the handover and maintenance-contract structure used across smart-home projects generally.
