What Goes Wrong

Why some retrofits fail, and how to avoid it

The difference between a retrofit that lasts and one that fails within months comes down to what happens before the motor is ordered.

Motor Strain

Fitting a motor to a sagging or binding gate puts constant load on the drive unit, causing premature failure within months.

Gate Assessment First

Balance, hinge condition, and alignment are checked before any hardware is selected, so the motor works within its rated load.

Wrong Motor Matched

A swing gate operator fitted to a sliding configuration, or a motor undersized for the gate weight, will stall or damage the leaf.

Configuration-Matched Hardware

The motor and control box are selected specifically for swing or sliding setup and the gate’s material and weight.

No Safety Sensors

Automation without photocells or safety edges creates a crush risk, and falls outside DHF standards for powered gate installations.

Sensors in Every Spec

Safety edges and photocells are included in every retrofit specification, not offered as an optional add-on.

Hidden Repair Costs

Discovering post rot or a warped gate leaf on installation day delays the job and adds unplanned cost the customer was not prepared for.

Pre-Order Survey

Any repair work needed is identified at survey stage, before hardware is ordered, so the quote reflects the full scope.

Scope of Work

What a gate automation retrofit covers

From a single swing gate to a pair of heavy wrought iron leaves, the scope is matched to what is already in place.

Hinge & Post Inspection

Checks post stability and hinge wear before motor fitting.

Gate Balance Check

Confirms the leaf moves freely without binding.

Opening & Closing Cycle Test

Verifies travel limits, sensor response, and remote range.

Manual Release Demo

Handover includes a walkthrough of the manual override.

Assess, Match & Automate

How an existing gate is assessed and set up for automation

Most manual gates can be motorised, the assessment confirms whether yours is ready now or needs minor work first.

The retrofit process starts with a gate assessment, not a motor selection. The installer checks gate balance, hinge and post condition, alignment, gate type, and the weight of the leaf. Brentwood has a mix of older detached homes and period properties where wrought iron or heavy timber gates are common candidates. An old or heavy gate that sags or binds will cause motor strain and premature failure if automation is added without addressing the underlying issue first.

Once the gate is confirmed as suitable, or minor repairs are completed, the motor and control box are selected to match the swing or sliding configuration and the gate material. Safety sensors are included in every retrofit specification, not added as an optional extra. Remote control handsets are programmed and tested, and keypad entry can be added at the same time if hands-free access from outside the vehicle is needed.

Many Brentwood driveways are accessed from busy roads, making hands-free operation a practical daily benefit rather than a convenience upgrade. The final opening and closing cycle test confirms travel limits, sensor response, and remote range. The manual release is demonstrated at handover so the gate can be operated by hand during a power cut without needing to call anyone out.

Why Choose Us

Why arrange your retrofit through us

Every job is arranged with a vetted local installer who follows a defined scope, survey first, hardware second, safety sensors included.

Gate Safe Standards on Every Job

Every retrofit is specified and fitted to Gate Safe standards, covering both the mechanical and safety requirements.

DHF Safety Edges & Photocells

Safety edges and photocells are specified to DHF standards on every job, not priced as optional extras.

Survey Before Any Hardware Is Ordered

The gate is assessed before hardware is selected, so the quote reflects the actual scope and there are no day-of surprises.

Motor Matched to Gate Type & Weight

Swing and sliding configurations are assessed separately, and the operator is sized to the gate’s weight and material.

Vetted Local Installers

We connect customers with vetted independent local partners who carry out the survey, supply, and installation.

The Process

From first enquiry to hands-free access

  1. 01

    Describe Your Gate

    Tell us the gate type, approximate width, and power supply so we can arrange the right local installer for your property.

  2. 02

    Survey & Quote

    The installer visits to assess balance, hinges, alignment, and gate weight, then provides a full quote covering all hardware and labour.

  3. 03

    Fit, Test & Hand Over

    Motor, control box, and safety sensors are fitted and cycle-tested, then the manual release is demonstrated before the installer leaves.

Common Questions

Questions about retrofitting gate automation

  • Can my existing gate be automated without replacing it?

    Often yes. The gate needs to be checked for weight, alignment, hinge condition, and how it opens. If the structure is sound, a motor and control box can be added without changing the gate itself. If there is sag or binding, minor repair work is identified at survey stage before any hardware is ordered.

  • Will automation work on a heavy wrought iron or timber gate?

    Heavy gates are common candidates for retrofitting, but the motor must be rated for the gate’s weight. The survey confirms the leaf weight and selects an operator with the correct torque rating. If the gate sags or binds, that is addressed before the motor is fitted.

  • Are safety sensors required, or are they optional?

    Safety edges and photocells are included in every retrofit specification to meet DHF standards. A powered gate without safety sensors creates a crush risk and does not comply with the standards that apply to automated gate installations.

  • What is the difference between a swing gate and a sliding gate retrofit?

    Swing gates use ram or underground operators fitted to the hinge side of each leaf. Sliding gates use a rack-and-pinion or underground drive unit running along the gate’s travel path. The hardware, wiring, and setup are different, which is why the gate type is confirmed at survey before any equipment is selected.

  • What happens if there is a power cut?

    Every installation includes a manual release, demonstrated at handover. This lets the gate be opened and closed by hand without tools or a call-out, so a power cut does not leave the entrance blocked or stuck open.
