Security Shutters for a Garden Room: A Simple Buyer’s Guide

Yes, you can fit security shutters to a garden room. They go over the doors and windows, which are the weak spots on any garden building. The right choice depends on your openings, your budget and how you use the room. This guide keeps it simple and walks you through each step, so you don’t have to trawl through pages of shutter jargon.

We sell garden log cabin kits, including bespoke builds, so we know how much the door and window layout matters. The best time to plan security is before the cabin is made. We’ll show you why below.

TL;DR

• Shutters can be fixed panels, hinged, bi-fold, sliding or roller. Pick the type that suits each opening.
• Look for a tested rating. LPS 1175 is the standard UK shutter ratings are measured against, and each step up costs more.
• Fitted prices for a domestic shutter run from about £450 for a manual window shutter to £1,800 for a wide patio door shutter.
• Internal shutters rarely need planning permission. External ones can, so check with your council first.
• Plan the doors, windows and glass at the design stage. A bespoke cabin lets you build security in from the start.

Why garden rooms need a little extra thought

A garden room sits away from the house. Nobody sees the doors and windows from the kitchen at night. If you keep a laptop, tools, a bike or hobby kit in there, that matters.

The good news is that you have lots of options, and they work best together. Strong doors, good locks, tough glass, lighting and an alarm all play a part. Shutters are one layer on top.

One UK council planning guide points out that shutters aren’t the only answer. It lists laminated safety glass, lighting, cameras and internal grilles as alternatives it often prefers. You can read that in Dudley Council’s planning advice. Another council’s guidance says ground floor glazing should include a laminated pane of at least 6.4mm, unless a roller shutter or grille protects it.

That’s why we talk about glass and shutters together. If you want to see how tougher glazing is specified for garden rooms, our guide to laminated security glass for garden rooms is a good next read.

The main types of security shutter

There isn’t one kind of shutter. Here are the ones you’ll come across, in plain words.

Roller shutters

A roller shutter is a curtain of slats that rolls up into a box above the opening. It suits windows and also wide glass doors. You can have it worked by hand or by motor.

A UK guide to shutters explains that surface-mounted shutters are fitted to the outside of an existing building, which makes them a good fit for adding to something already built. Built-in shutters hide the box inside the wall for a neater look. On a timber cabin, the surface-mounted route is usually the simpler one, though the box needs a firm fixing point.

The same guide says manual shutters are cost-effective for smaller windows. Electric ones are handier for larger windows or several shutters, and can run from a wall switch, remote or smart home system.

Hinged, bi-fold and sliding shutters

These look more like traditional shutters. One UK maker of aluminium security shutters says its range includes fixed panels for high windows, hinged shutters for standard windows and doorways, bi-fold shutters on a track for wider patio doors, and sliding shutters. They can be fitted inside the reveal or face-fixed onto the structure.

They sit nicely on a summer house or pavilion, where you want a softer look than a roller box.

Quick comparison

Solid, see-through or ventilated?

This is the choice people often miss. The slats can be solid, insulated, or perforated.

A UK cost guide says insulated or foam-filled slats add £150 to £500. They are quieter and warmer, but not stronger. Perforated or brick-bond slats add £100 to £400 and let light through.

Here’s how we’d think about it:

• Solid: Gives the most cover. Good if the cabin sits empty for long stretches.
• Insulated: Nice if you use the room in winter and want less noise and heat loss.
• See-through or perforated: Lets light in and lets you check the room from outside. Good for a summer house you like to look at.

Looks matter too. Council guidance often warns that closed solid shutters can feel unwelcoming and attract graffiti. That advice is written about shopfronts, but it’s a fair reminder to think about how the shutters look when they’re down in your own garden.

Security ratings in plain English

Not all shutters are equally tough. In the UK, shutters are tested against a standard called LPS 1175. It tests them against set tools and set times. According to a UK roller door firm, ratings run from A1 (opportunistic, hand tools, about one minute) up to H20 (professional, power tools, twenty minutes).

For a home garden room, you’ll mostly see the lower grades. The same firm says A1 and A3 are the usual baseline for domestic jobs, and B3 and C3 are more typical when an insurer insists. It also says each step up adds roughly 15 to 25% to the cost.

Police-backed Secured by Design guidance, as quoted in one council document, sets the minimum for roller shutters and grilles at LPS 1175 Issue 8.1:2020 Security Rating B10 or above. It adds that the right level depends on crime risk, location and what’s being protected.

Here’s the simple version:

1. Ask any supplier which LPS rating the shutter has, and which issue of the standard it was tested to.
2. Check your home insurance wording. Some insurers set their own security rules for outbuildings.
3. Match the rating to what’s inside. A cabin with a mower and deckchairs needs less than one holding expensive office kit.

What shutters cost in the UK

Prices vary by size, rating and whether the shutter is manual or electric. One 2026 UK cost guide gives these fitted ranges:

Those figures come from this UK security shutter cost guide. The same guide says London prices for electric window shutters run 25 to 30% above the UK average.

A few things push the price up:

• A higher LPS rating
• Insulated slats
• A motor and remote
• Wide doors, which are usually electric by 2 to 3m
• An emergency release (more on that below)

Treat these as ballpark figures. Always get a written quote for your own openings.

Measure twice: checking your cabin first

Shutters are made to measure, so small mistakes cost money. Before you order, check these points:

• Opening size and shape. Odd shapes need a special order.
• Fixing space. There has to be solid timber or frame to fix to.
• Room for the box and guide rails. A roller shutter needs space above and at the sides.
• Inside or outside fitting. This changes how you measure.

A UK guide stresses that accurate measuring is essential, and lists window size, fixing space, building construction and clearance for the box and rails as the key factors.

One UK made-to-measure supplier gives a handy rule. For surface fitting, measure the structural opening in millimetres, and the guide tracks add about 110mm to the overall width. For fitting inside the reveal, use the narrowest measurement and take off around 5mm for tolerance. The shutter should go in plumb and square.

On a log cabin, remember that timber moves a little with the seasons. Ask your fitter how they allow for that. And think about the roof overhang and any porch, since they can get in the way of a shutter box.

Do you need planning permission?

Usually this is simple. One UK guide says internal shutters need no planning permission, while external shutters may need it depending on the area. Rules can be stricter in conservation areas.

Council guidance backs up the pattern. Planning permission is needed for alterations that materially affect the outside look of a building, and for listed buildings almost any security measure, inside or out, would need consent.

For a garden room, that means:

1. Inside shutters: rarely a problem.
2. Outside shutters: check with your local council first, especially if you’re in a conservation area or the cabin is part of a listed property.
3. Not sure? Ring your council’s planning team. It’s quick and free to ask.

One UK shutter guide also notes that if your garden room is in a conservation area or is part of a listed building, check with the local authority about the outside look. Internal louvred shutters rarely attract scrutiny.

Our own advice: if you’re also adding glazing or integral blinds, read our page on garden room glazing and building regulations too.

Safe use: getting out when the shutters are down

This one matters. A shutter that is down has to go up before anyone can leave. A roller door specialist points out that a battery back-up is not optional where a roller door is the only way out of a detached building, and that powered shutters should have a battery back-up and a manual hoist.

A UK cost guide adds that if a shutter covers an exit, it needs a manual override that works from inside without a key. A built-in override adds £200 to £600.

So, simple rules:

• Never lock yourself in. You should always be able to open the shutter from inside.
• If it’s electric, choose a model with a battery back-up for power cuts.
• Keep the guide rails clear of leaves and dirt, and check the shutter moves smoothly a few times a year.
• Don’t rely on shutters alone. Add lighting, good locks and an alarm.

If you have a key-operated lock or a motor, keep the spare key or remote somewhere safe in the house, not in the cabin.

A word from us

We build garden cabins for a living, and we see the same thing again and again. People add security last, once the cabin is up. It’s much easier, and often neater, to think about it first.

When we make a bespoke cabin, you choose where the doors and windows go, how big they are and how the glass is set. You can ask for double glazing, insulation and a layout that suits you. That gives you a head start. Fewer and smaller openings on the side facing the lane. Stronger door choices. Glass chosen to suit the way you use the room.

Shutters can be a good extra layer, particularly on a wide patio door. But the cabin itself is the base. A well-built cabin with sensible openings is easier to protect, whatever you add later.

If you’re not sure where to start, tell us how you’ll use the room and we’ll talk it through with you. No pressure, and no jargon.

Choosing the cabin style that suits your security plan

Different cabins call for different approaches. Here are a few pointers.

Log cabins with a pitched roof

A classic apex roof cabin has a clear front wall for doors and windows. That makes it easy to put the glazed parts on the side you can see from the house.

Summer houses and pavilions

These tend to have lots of glass, which is part of the charm. If that’s what you want, look at our garden summer houses and garden pavilions. Pair big glass areas with laminated panes, and think about shutters for the widest doors.

Multi-room cabins

A multi-room log cabin lets you keep valuables in an inner room with fewer windows. That’s a smart way to add security without any extra hardware.

Doors

The door is the first thing a thief looks at. Our guide to types of cabin doors shows the choices, and our page on bespoke security features covers more ideas.

Privacy and looks

Shutters aren’t the only way to stop people looking in. See our tips on garden room privacy, and our guide to choosing windows for garden rooms. If you plan to paint or stain the outside, check our external finishes guide before you fix anything to the walls.

A simple step-by-step plan

1. Decide what you’re protecting. Think about the value of what’s inside and how often the room is used.
2. Check your insurance. Ask what they expect for an outbuilding.
3. Strengthen the basics. Good door, good locks, laminated glass, lighting.
4. Choose the shutter type. Roller for windows, bi-fold or sliding for wide doors.
5. Pick the rating. Ask for the LPS grade and the issue it was tested to.
6. Measure carefully. Or get a fitter to do it.
7. Check planning. Outside fitting? Ring your council if in doubt.
8. Make sure you can get out. Manual override or battery back-up.

FAQ

Can you fit security shutters to a log cabin?

Yes, in most cases. The shutter needs solid timber to fix to, and enough room for the box and guide rails. Get a fitter to check your openings before you order. If you’re having a bespoke cabin made, mention shutters at the design stage so the openings can be planned for them.

Are internal shutters as secure as external ones?

They can be, if the shutter is tested and well fixed. Internal shutters also tend to avoid planning questions, as one UK guide explains. The best choice depends on your glass, your layout and your insurer’s rules.

How much do garden room security shutters cost?

One 2026 UK guide gives fitted prices of £450 to £900 for a manual window shutter, £700 to £1,400 for an electric one, and £900 to £1,800 for a patio door shutter 2 to 3m wide. Your quote will depend on size, rating and extras.

What rating should I look for?

Look for a shutter tested to LPS 1175. According to a UK roller door firm, A1 or A3 is the usual baseline for homes, while B3 and C3 are more common when an insurer asks for more. Check with your insurer first.

Do I need planning permission?

Inside shutters rarely do. Outside ones might, especially in a conservation area or on a listed property. Your local council’s planning team can tell you in a quick call.
