What a Properly Specified Aluminium Side Gate Actually Needs to Do
Ask a burglar which entry point on a typical UK home gets tested first, and the answer is rarely the front door. It is the side gate – the half-rotten timber panel between the house and the garage, the wobbly latch, the daylight gap above the bolt. Aluminium side gates in the UK have quietly become the answer to a problem most homeowners have not yet articulated, and most still specify them the way you specify a kettle: pick one, buy it, move on. That approach is what ruins them.
Treat the side gate as a working component of the home, not a piece of decoration with a latch attached. It carries the dog walker, the bin run, the postman, deliveries, kids cutting through to the garden, and a Yorkshire winter shoulder-charging it twice a season. At Euro-Fences we make the side and pedestrian gates we install across East Riding ourselves, in Driffield, and the difference between a well-specified one and a generic catalogue purchase shows up around year three – when the timber sags and the steel hinges weep rust onto the brickwork.
The Brief Most Homeowners Don’t Write (But Should)
Before sizing, colour or automation, write down what the gate actually has to do. Five questions sort out most of the spec.
Who uses it, and how often? A gate the dog walker opens twice daily wants different hinges from one a postman touches once a week. What is it keeping out, and what is it keeping in? A toddler and a Labrador want different things from the same gate. What does the wind do here? Driffield gardens see different exposure to coastal properties in Hornsea or Bridlington, where on-shore winds turn an under-built gate into a sail. What sits on the other side – bin store, garden, oil tank, hot tub? The answer drives the privacy spec. And how does the gate read in the elevation of the house? A side gate visible from the road is part of the kerb appeal whether you wanted it to be or not.
Most homeowners who ring us already know the answers. They have not yet linked them to a specification.
Why Aluminium Has Quietly Taken Over Side Gate Specs
Traditional timber side gates remain the default in builder’s merchant lists, and the default reason people ring us back five years later. In the UK climate – 600 to 900mm of annual rainfall, freeze-thaw cycles, the occasional fortnight at minus five – a softwood gate needs treating every two to three years and replacing inside a decade. Wrought iron lasts longer, but on the East Riding coast we have seen iron gates in Bridlington and Hornsea showing surface rust within eighteen months. Salt-laden air travels ten miles inland on a strong easterly. uPVC sags. Composite holds up, but tends to cost more than an aluminium equivalent without matching the longevity.
Aluminium does not rust. It does not rot. Grade 6063 or 6082 extrusions, the alloys we work with, sit happily for thirty years with no maintenance beyond a wash. A 60 to 80 micron powder-coated finish keeps the colour stable through UV exposure and salt air. Lighter than steel, it puts less load on the hinges, which means cheaper fixings and longer hinge life. None of this is marketing. It is what shows up when you walk back into an installation five years on.
Sizing: Where Most UK Specifications Quietly Fail
Width
Standard pedestrian gate width in the UK sits at around 900mm – fine for most paths between a house and a boundary fence. Narrow Victorian or Edwardian terraced passages, common across Hull and Beverley, sometimes need a slim 800mm. Wider access for a wheelbarrow or a mobility scooter runs at 1.0 to 1.2m. Measure between the finished pillar faces, not between brick courses, and deduct 40 to 60mm for hinge clearance and latch overlap. That margin is where most off-the-shelf side gates fail before they are even hung.
Height
Most rear-garden installs sit at 1.8m (6ft) – high enough to shield bins, deter casual climbers, and match a 1.8m fence line. Going to 2.0m starts to interact with planning rules. In a front garden abutting a public highway, the limit drops to 1.0m without permission. The thresholds are published on the Planning Portal.
Planning Permission and Boundary Realities
Most side gates fall inside Permitted Development. The two situations that catch buyers out are conservation areas and Article 4 Direction zones, where some or all permitted rights are removed – common across parts of York, Beverley town centre, and Driffield’s older streets. Listed buildings need consent for almost any external alteration. If the gate sits on the legal boundary line with a neighbour, the Party Wall etc. Act 1996 may apply, and a brief conversation before install saves considerable awkwardness afterwards.
We covered the regulatory framework in more depth elsewhere; the same Permitted Development rules that govern driveway gates apply to side and pedestrian gates with surprisingly little variation.
Matching the Side Gate to the Driveway Gate
A matched suite – driveway gate and side gate in the same range, same RAL colour, same infill – is one of the small specification choices that lifts a property’s frontage immediately. The visual rhythm carries from one side of the drive to the other, and from the road the property reads as designed rather than assembled.
For narrow side access between buildings, the Comb vertical slat design, particularly suited to narrow side access is the one we recommend most often – vertical lines suit tight pillars and read clean from every angle. For matched suites on contemporary builds we lean toward the Modern range; for character properties – Yorkshire stone cottages around Cranswick, Rudston and Nafferton – the Nu wood-effect range gives a timber appearance with aluminium’s behaviour underneath. RAL 7016 anthracite grey remains the most popular finish across our installations, though the full fan has over 200 options if the rest of the property points elsewhere.
Automation: When a Side Gate Earns an Intercom
Most side gates stay manual, and that is the right answer. The use case for automation is narrower than people assume. A gate the dog walker opens four times daily, a gate controlling access to a holiday let, a side entrance for a dual-occupancy property – these earn an intercom and a smart lock. A linear actuator or underground hinge motor handles the weight without difficulty; audio or video intercoms tie into the property’s existing system; smartphone control through CAME, Nice or BFT lets you grant access from the kitchen or from Spain. If the gate sees fewer than five uses a day from familiar hands, a magnetic latch and a good drop-bolt cost a fraction and last just as long.
Installation Realities: Posts, Foundations, Fixings
The gate is half the spec. The post is the other half. Existing brick pillars handle a 1.8m aluminium pedestrian gate well if the brickwork is sound and the mortar is not crumbling; we fix into the brick with M10 chemical-set anchors. Where no pillar exists, we set a powder-coated steel or aluminium post into a 600mm-deep concrete foundation, with a wider base where the soil is light or the gate runs wider than 1.0m.
Hinges follow the gate weight: ball-bearing strap hinges for gates up to about 35kg, bottom-bearing hinges for anything heavier or in daily use. Self-closing springs, magnetic catches, drop-bolts for double leaves, finger-trap guards where children pass through regularly – all of it sits inside our pedestrian and side gate range, built in Driffield and adjusted to the property rather than ordered off a list.
Specifications from Recent East Riding Installations
Four representative installations from the last twelve months across our patch:
A Driffield semi-detached property – 900mm wide, 1.8m tall, Comb vertical slat in RAL 7016 anthracite grey, fixed into existing brick pillars, magnetic latch and self-closing spring. A coastal property near Hornsea – 1.0m wide, 1.8m tall, Modern range matched to a 4.0m double driveway gate, automated with a linear actuator and a video intercom, finished in RAL 9005 jet black. A character cottage in Cranswick – 850mm wide, 1.5m tall, Nu wood-effect range to match the property’s existing oak-stained features, manual with a thumb-latch. A larger property in Nafferton with a long shared driveway – twin pedestrian gates flanking the entrance, Castle range, RAL 7016, height stepping down from 1.8m at the house to 1.2m at the verge.
Each spec started with the brief, not the catalogue.
Frequently Asked Questions
How wide should an aluminium side gate be in the UK?
Standard pedestrian width runs at around 900mm. Narrow terraced passages may need 800mm; access for wheelbarrows or mobility scooters should be 1.0 to 1.2m. Measure between finished pillar faces and deduct around 50mm for hinge and latch clearance.
Do I need planning permission for a 1.8m aluminium side gate?
Usually not. Permitted Development Rights allow gates and fences up to 2.0m in height in rear and side gardens. A front garden abutting a public highway drops to 1.0m. Conservation areas, Article 4 zones and Listed properties may require consent – check with your local planning authority before ordering.
How long do aluminium side gates last in the UK climate?
A properly specified powder-coated aluminium side gate in grade 6063 or 6082, with a 60 to 80 micron finish, lasts 30 years or more with no structural maintenance. Coastal installations across East Riding see no measurable difference, where timber or wrought iron would have failed inside a decade.
Can a side gate have an intercom or smart lock?
Yes. Audio or video intercoms tie into the gate’s lock and release; smart locks with smartphone control are widely available. The strongest use case is high-frequency or remote access – dog walkers, holiday lets, dual-occupancy properties.
How much does an aluminium side gate cost?
Pricing depends on width, height, model, finish and whether automation is included. We provide free written quotes after a short site discussion or measured visit, broken down by component so you see exactly what the spec includes.
Can you match a side gate to a driveway gate?
Yes – a matched suite is one of the most effective frontage upgrades available. We build the side gate and driveway gate from the same range, in the same RAL colour, with matching infill and hardware.
