Summary
Electric gates are sold to customers as a single visible product — the gate and the motor — but priced correctly they are five separate cost centres: the gate itself (if not already existing), the motor and control package, the electrical supply run, the safety compliance package, and the commissioning/certification work. Installers who price only the visible hardware and a day's labour routinely under-quote by £800–£1,500 once the compliance paperwork, force testing and cable burial are accounted for properly.
The compliance side of this trade is not optional extra work — it is where the legal liability sits. Two child fatalities in the UK (2010 and 2017) from non-compliant automated gates led to active enforcement by the HSE and Local Authority Building Control. An installer supplying and fitting an automated gate without a Declaration of Conformity and a documented risk assessment carries potential criminal liability under the Supply of Machinery (Safety) Regulations 2008. This is covered in full in electric gates installation; this guide focuses specifically on how to price the job profitably while carrying that compliance work properly, not on the technical installation detail itself.

Key Facts
- Regulatory basis — Supply of Machinery (Safety) Regulations 2008 (transposing EU Machinery Directive 2006/42/EC), BS EN 12453 (safety in use), BS EN 12604/12605 (mechanical requirements)
- Gate types priced separately from motors — swing (single/double leaf), sliding (track or cantilever), bi-fold
- Motor types — articulated ram (24V DC, most common residential), underground hydraulic (premium, heavy gates), sliding rack-and-pinion
- Mandatory safety package — photocells (minimum one pair), safety edges or force-limiting motors, manual release mechanism, warning lights and signage
- Force testing — required at three points per gate leaf (top, middle, bottom); max 400N peak impact force, 150N continuous compression per BS EN 12453
- Declaration of Conformity — must be issued by the installer as the "responsible person" for the assembled machine; this is a distinct cost/liability item, not paperwork you can skip to save time
- Risk assessment — written document covering trapping points, shear points, pedestrian conflict, child access — retained by the installer
- Part P electrical notification — the new 230V circuit to the gate control panel is notifiable; competent person scheme certification (NICEIC, NAPIT, ELECSA) required
- Cable burial — SWA armoured cable, 600mm depth minimum with warning tape, to BS 7671:2018+A4:2026
- DHF Code of Practice — TS 011 (industrial gates), TS 012 (residential gates) — UK trade body technical guidance, not a statutory instrument but widely used as the compliance benchmark
- Maintenance contracts — 6 or 12-monthly service with force re-test and log; a recurring revenue line often left off the initial quote entirely
- Lead time — 2–6 weeks for motor/control panel supply; longer for bespoke gates or underground hydraulic systems
- Backup power — battery backup for the control panel, £150–£350 supplied, recommended and increasingly expected as standard by customers

Detailed Guidance
Pricing the gate and motor package
Start with the gate itself. Many jobs are motorising an existing gate, which removes this line entirely — confirm the existing gate's weight and condition before quoting, since underspecifying the motor for an existing heavy wrought-iron gate is a common and expensive mistake. Where a new gate is required, price it as a separate supply item (see metal railings and gates for material specification and cost ranges).
Motor selection is driven by gate weight, leaf length and driveway gradient, not by customer preference alone:
- 24V DC articulated ram — the standard residential choice; cost-effective, reliable, mature spare-parts ecosystem. Suitable for leaves up to roughly 2.5m and moderate weight.
- Underground hydraulic — required for heavy wrought-iron gates, longer leaves (up to 4m), or where the customer wants the motor invisible when the gate is open. Roughly double the cost of articulated rams.
- Sliding — needed where swing space is unavailable, or the driveway gradient exceeds roughly 5% (swing gates on a falling driveway can bind). Cantilever sliding avoids a ground track but costs more than track-mounted.
Quote motor and gate as supply items with a clear source and lead time — don't estimate the motor package, get a firm supplier quote, since pricing varies meaningfully between manufacturers (CAME, Nice, FAAC and budget alternatives) for the same nominal spec.
The electrical run — commonly underpriced
The electrical supply run from the consumer unit to the gate control panel is priced by the linear metre of SWA armoured cable, buried to 600mm depth with warning tape. On a typical UK driveway this run is 10–30m, but on longer or rural driveways it can exceed 50–80m — always measure on site rather than estimating from a photo or verbal description.
Price components:
- Trenching and reinstatement: £15–£30/linear m depending on surface (grass vs block paving vs tarmac reinstatement)
- SWA cable supply: £8–£15/linear m depending on cable size
- Termination and glanding at both ends: £80–£150 fixed
- Part P notification and certification: £150–£300 fixed fee
A 40m run through tarmac driveway requiring reinstatement can add £1,200–£1,800 to the job on its own — this is the line item most likely to be missed in a phone-quote or a quote given without a site visit.
The compliance package — do not discount this
The force testing, Declaration of Conformity and risk assessment are not administrative overhead to be absorbed into the labour day rate — they are the core legal protection for both the installer and the client, and should be priced as a distinct, visible line item on the quote (£150–£350 typical). Presenting this as a separate line also educates the customer on why a "gate installer" quote from a fencing contractor without this documentation is a red flag, not a bargain.
Do not fit an automated gate without completing and retaining:
- A written risk assessment (trapping points, shear points, pedestrian/child access)
- A force test at three points on each leaf, documented with readings
- A signed Declaration of Conformity, with the installer named as the responsible person
- A user manual and maintenance logbook handed to the client
Margin and markup structure
Electric gate installation carries a wide margin range because of the mix of supplied hardware (thin margin, competitive supplier pricing) and specialist labour/compliance work (higher margin, less price-comparable by the customer). A reasonable structure:
- Hardware markup — 15–25% on motors, control panels and safety devices sourced from a trade supplier
- Gate markup — 20–30% if supplying a new gate (higher than hardware because more bespoke/less price-comparable)
- Labour — priced at full day-team rate, not discounted against the hardware margin
- Compliance package — priced as a fixed fee reflecting the liability carried, not discounted
- Overall gross margin — 20–30% is standard for a complete supply-and-fit job
Worked example — double swing gate, existing gates, 25m SWA run, standard site:
- Motors (articulated pair): £950
- Control panel + receiver: £380
- Photocells + safety edges: £320
- Battery backup: £220
- Access control (keypad): £350
- Electrical run (25m SWA, trenching, Part P): £1,050
- Installation labour (1.5 days, 2 installers): £900
- Force testing + Declaration of Conformity + risk assessment: £250
- Cost subtotal: £4,420
- Markup on hardware/materials (20% blended, on £2,220 of motors/panel/photocells/battery/access-control): £444
- Margin on labour and compliance (25%, on £2,200 of electrical run/install labour/force testing): £550
- Net price (cost + markup + margin): £5,414
- VAT (20%): £1,083
- Quoted price: £6,497 inc. VAT
Maintenance contracts — the recurring revenue most installers leave on the table
Every electric gate should be serviced 6 or 12-monthly, with a re-run of the force test and an updated log entry — required to keep the Declaration of Conformity meaningful over the life of the installation. Offer this at the point of sale as a fixed annual or bi-annual fee (£120–£220 per visit) rather than leaving it as an afterthought; conversion rates on service contracts offered at handover are significantly higher than contracts pitched via a follow-up call months later.
Frequently Asked Questions
Can I quote an electric gate job without a site visit?
Not reliably. The electrical run length, ground conditions for trenching, driveway gradient (which affects motor type), and existing gate weight and condition (if motorising an existing gate) all materially change the price and cannot be assessed from a phone description or photos alone. A site visit is standard practice for this trade, not an optional extra.
Do I need to charge separately for the Declaration of Conformity and risk assessment, or fold it into the labour rate?
Charge separately and show it as a line item. It signals to the customer that this is compliance work carrying real legal weight, distinguishes a properly-compliant quote from a cheaper competitor who may be skipping this step, and protects your margin — this work takes real time (typically 1–2 hours for force testing and documentation) and should not be absorbed silently into the install day rate.
What's the most common reason electric gate jobs go over budget?
Underestimating the electrical run — either the linear distance from consumer unit to gate, or the surface reinstatement required (tarmac and block paving cost significantly more to trench and reinstate than grass or gravel). Always measure the actual cable route on site before pricing, not the straight-line distance on a plan.
Should I offer a maintenance contract at the point of installation?
Yes — pitch it at handover, not as a follow-up. A 6 or 12-monthly service (force re-test, safety device check, log update) is required to keep the gate's Declaration of Conformity meaningful over time, gives the installer a recurring revenue stream, and is an easier sell immediately after the client has seen the compliance work done properly during installation.
