Summary
Access control systems range enormously in scope, from a single fob-operated door strike on a side gate to a fully networked multi-door system with audit trails, integration into fire alarm release (per BS 7273-4) and CCTV. Pricing accurately depends on getting the scope right up front — door count, whether the system needs to be networked or standalone, cabling distances, and whether fail-safe or fail-secure locking is required on fire escape routes, which is a compliance requirement, not a design preference.
The most common pricing mistake is quoting a single-door job rate for what turns out to be a multi-door networked requirement once the client clarifies they want the office, the store cupboard and the rear fire exit all on the same system with a management dashboard — always confirm door count and whether central management/reporting is wanted before pricing, since the jump from standalone to networked more than doubles both material and labour cost per door.
Materials cost is driven by reader type (basic proximity, DESFire/encrypted, or biometric), controller/cabling requirements, and lock hardware type (magnetic lock, electric strike, or motorised lock), while labour is driven by cabling runs (especially in solid-wall or listed properties where containment is harder to conceal) and fire door integration requirements.
Key Facts
- Standalone single-door kit (keypad or fob, electric strike) — materials typically £150-£400 for the reader/controller/strike/power supply, plus consumables (cable, containment, fixings)
- Networked reader (per door, card/fob managed centrally) — materials typically £300-£700 per door including reader, controller share, and lock hardware
- Biometric or high-security reader (DESFire EV3, fingerprint) — materials typically £400-£900 per door
- Electric strike (fail-secure, standard timber/metal door) — £40-£120
- Magnetic lock (fail-safe, required on fire escape routes) — £60-£180 plus door contact and release button
- Central controller/software (small networked system, 3-5 doors) — £600-£1,800 for hardware plus licensing where the software is subscription-based
- Cabling — typically Cat5e/Cat6 or dedicated low-voltage cable run in containment; budget £4-£8 per metre for cable and containment materials on a straightforward run, more in solid-wall or listed properties requiring surface containment or careful chasing
- Labour, single-door standalone — typically half a day to 1 day (£150-£350)
- Labour, per additional networked door — typically 2-4 hours per door once the controller and backbone cabling are in (£70-£180 per door)
- Fire door integration (fail-safe release on fire alarm activation) — additional £150-£400 per door for the interface relay/module and testing, required wherever access control is fitted to a designated fire escape route per BS 7273-4
- Day rate, access control/security installer — £220-£350 regional, £300-£450 London
- VAT — standard rate 20% applies to both materials and labour on domestic and most commercial access control installations

Detailed Guidance
Scoping the job before quoting
Confirm the number of doors, whether the client wants standalone (each door independent, no central record of who entered when) or networked (central controller, audit trail, remote management), and whether any of the doors are on a designated fire escape route — this last point determines fail-safe vs fail-secure locking, which is a compliance decision, not a customer preference, per BS 7273-4 and the building's fire strategy. See access control and access control systems guide for the underlying technical standards.
Pricing cabling and containment realistically
Cabling cost is the most commonly under-priced element on access control jobs, particularly in older solid-wall properties where surface containment (trunking, conduit) is needed rather than a quick chase-and-plaster run, or where cable runs have to go through fire-separating elements requiring proper fire-stopping. Walk the actual cable route before quoting rather than estimating from a floor plan — a run that looks short on a drawing can be significantly longer once it has to avoid structural elements, other services, or aesthetically sensitive areas.
Pricing fail-safe vs fail-secure correctly
Fail-safe locks (typically magnetic locks) unlock on power loss or fire alarm activation and are required on fire escape doors so occupants are never locked in during an emergency. Fail-secure locks (typically electric strikes) remain locked on power loss and are used where security in a power cut matters more than free egress — never fitted to a required fire escape route. Pricing must reflect the correct hardware for each door's fire strategy role, and a quote that specifies the wrong lock type on a fire door is a compliance failure that can require costly rework, not just a design preference to revisit later.
Worked example: 4-door networked office system
A small office wants networked fob access on the main entrance, a rear fire exit, a server room and a stock room, with a central controller and basic reporting. Materials: 4× networked readers (£500 average) = £2,000; central controller/software = £1,200; fail-safe magnetic lock + release button for the fire exit door = £220; 3× electric strikes for the other doors = £270; cabling and containment for 4 runs averaging 15m each = £480. Materials subtotal: £4,170. Labour: 3 days at £280/day = £840, plus fire door integration and testing = £300. Labour subtotal: £1,140. Total cost: £5,310. Applying a typical 20-30% margin gives a quoted price in the region of £6,400-£6,900 to the client, before VAT.
Frequently Asked Questions
Do I need to charge for ongoing software licensing separately?
Where the access control software is subscription-based (common with cloud-managed systems), this should be itemised as a separate recurring cost to the client rather than folded into the one-off installation price, so the client understands it as an ongoing commitment rather than a one-time material cost.
How do I price integrating access control with an existing fire alarm panel?
This requires coordination with the fire alarm installer/maintainer, since the interface must be correctly specified in the fire alarm cause-and-effect schedule (see fire alarm interface with other systems). Price this as a distinct line item covering the interface relay hardware, the coordination/commissioning time with the fire alarm contractor, and testing — it is rarely a simple bolt-on and underpricing the coordination time is a common source of margin erosion on this type of job.
Should biometric readers be priced differently because of GDPR requirements?
Yes — biometric data is a Special Category of personal data under UK GDPR, requiring explicit consent and additional data handling safeguards. This doesn't usually add significant installation labour, but it's worth flagging to commercial clients as a compliance responsibility they take on, and can justify positioning biometric systems at a premium price point reflecting the added specification and reader cost, not just the hardware difference.
What margin should I apply on materials for access control work?
Materials margin on security/access control equipment is typically in the 20-35% range depending on your supplier relationships and whether you're specifying branded/proprietary systems (which often carry better trade margins) versus generic components — consistent with typical electrical/security trade markup practice.
