A good garden awning turns a sun-blasted patio into a shaded spot you can actually use all afternoon. The question most people get stuck on is whether to go manual or electric — and whether the extra cost of a motor is worth it. We compared two well-established 3×2.5m awnings that sit at opposite ends of that decision: a straightforward manual crank model and a full-cassette electric awning with remote control.
Both are sized for a standard patio or set of doors, both mount to a solid wall, and both need to go up the same way — but day-to-day, they’re quite different products to live with. Here’s how they compare.
| Key Takeaways • The Greenbay Manual Awning (£329.99) is the better choice if you want dependable shade at a lower price and don’t mind a hand crank. • The Outsunny Electric Awning (£525.99) adds remote-control convenience and a fully enclosed cassette that protects the fabric when not in use — at nearly double the price. • Both require mounting to a solid concrete or brick wall. Neither is suitable for stud/timber-frame walls without additional fixings. • The Outsunny needs a mains power point within reach of its 5m cable — check this before buying. |
1. Greenbay 3×2.5m Manual Awning — Best Budget/Mid-Range

The Greenbay is a straightforward manual retractable awning built around a steel square torsion bar and aluminium roller. It’s part of a long-running product line sold across multiple sizes and colours, with a large accumulated review history on Amazon UK — a good sign for reliability in this category.
| Specification | Detail |
| Price | £329.99 |
| Dimensions | 3m width x 2.5m projection |
| Frame | Steel square torsion bar (35x35x1.2mm) + aluminium roller |
| Canopy fabric | 300g/m² PU-coated, water-resistant polyester |
| Operation | Manual steel crank handle (fixed to the left side) |
| Angle adjustment | 5°–35° from horizontal |
| Mounting | Solid concrete or brick wall only; wall brackets included |
| Certification | TÜV & GS approved |
| Pros | Cons |
| Sturdy steel torsion bar keeps the canopy taut and smooth to operate | Manual crank only — no remote or motorised option |
| Established product line with a long, largely positive UK review history | Some reviewers report the supplied wall bolts are shorter/lighter than ideal |
| Water-resistant, UV-resistant canopy fabric | Only suitable for solid masonry walls |
| Significantly cheaper than the electric alternative | Canopy sits exposed on the roller rather than in a protective cassette |
| No power source needed — works anywhere with a solid wall |
| Warning A recurring theme in reviews across this product line is that the supplied wall-fixing bolts are on the short/light side for some wall types. Several buyers replace them with their own masonry bolts or wall anchors (such as Screwfix Easyfix anchors) rather than relying on the ones in the box. This isn’t a defect specific to this listing — it’s a common complaint across budget awnings generally — but it’s worth budgeting an extra few pounds for proper fixings rather than assuming the included hardware is final. |
| Verdict If you want reliable, no-fuss shade and don’t mind winding a handle each time, the Greenbay is a well-proven choice at a fair price. Budget a little extra for better wall anchors and you should get years of use out of it. View on Amazon |
2. Outsunny 3×2.5m Electric Awning — Best Premium/Electric

The Outsunny steps things up with a remote-controlled motor and a full-cassette design, meaning the canopy folds completely inside a protective housing when retracted rather than sitting exposed on an open roller. Outsunny is a brand of Aosom, an established UK outdoor furniture retailer, and this model includes a manual crank as a backup if the motor or remote ever fails.
| Specification | Detail |
| Price | £525.99 |
| Dimensions | 3m width x up to 2.5m projection |
| Frame | Aluminium and steel frame |
| Canopy fabric | 280g/m², PVC-coated polyester, UV50+ rated |
| Operation | Remote control (electric) with manual crank backup (160cm handle) |
| Cassette design | Full cassette — canopy fully enclosed when closed |
| Power | Mains-powered; 5m cable |
| Mounting | Solid concrete or brick wall only; wall brackets included |
| Pros | Cons |
| Push-button remote operation — genuinely convenient for everyday use | Nearly £200 more than the manual option |
| Full cassette protects the fabric from weather and UV when retracted, extending its lifespan | Requires a mains power point within reach of the 5m cable — may mean extra electrical work |
| Manual crank backup means a power cut or remote failure won’t leave you without shade | Heavier and more involved to install than a manual awning |
| UV50+ rated canopy | More moving parts (motor, remote) mean more that could eventually need repair |
| Backed by an established outdoor furniture brand (Aosom) |
| Verdict If you use your patio often and want the shade up or down in seconds without winding a handle, the Outsunny’s convenience and cassette protection justify the premium — provided you’ve got a power point within reach and are comfortable with a slightly more involved install.

Installation & Operation Comparison
Price and specs only tell part of the story — how each awning actually fits into your routine and your property matters just as much.
| Factor | Greenbay Manual | Outsunny Electric |
| Typical install time | 1–2 hours, two people recommended | 1.5–2.5 hours, two people recommended (plus access to a power point) |
| Tools needed | Drill, masonry bit, spirit level | Drill, masonry bit, spirit level; may need an outdoor-rated power point installed by an electrician if none exists nearby |
| Ongoing operation effort | Manual winding each time, light physical effort | Push-button, minimal effort |
| What happens in a power cut | Unaffected — fully manual | Falls back to the manual hand crank |
| Weather protection when closed | Canopy exposed on the roller | Canopy fully enclosed in cassette, better protected from grime and UV when not in use |
Honest Limitations
- This comparison covers one size (3×2.5m) from each brand — both are available in other sizes and colours if this doesn’t suit your space.
- Neither awning is suitable for mounting on stud/timber-frame walls without additional, non-standard fixings — both are designed for solid concrete or brick.
- The Outsunny’s convenience depends on having a power point within reach; if you don’t have one nearby, factor in the cost of having one installed.
- Both are wind-vulnerable at full extension like most cantilevered awnings — retract in high winds regardless of which you choose.
- Installation for both is a two-person job in practice, even though official instructions sometimes suggest otherwise.

Frequently Asked Questions
Do I need planning permission for a garden awning?
In most UK cases, a retractable awning on a domestic property counts as permitted development and doesn’t need planning permission, but this can vary by property type, conservation area status, and local council rules. If in doubt, check with your local planning authority before installing.
Can I install a garden awning myself?
Both awnings here are designed for DIY installation onto a solid wall, and most buyers manage it with two people, a drill, and a masonry bit. The Outsunny’s electrical connection is straightforward if you already have a suitable outdoor power point nearby; if you need one installed, that part is a job for a qualified electrician.
What’s the real difference between manual and electric awnings?
Functionally, both provide the same shade once extended. The difference is entirely in day-to-day convenience: a manual awning needs a hand crank each time, while an electric one opens and closes at the push of a remote button. Electric models also tend to come with fuller cassette protection, which can extend the fabric’s lifespan.
How do I look after the fabric so it lasts?
Retract the awning in heavy rain or high winds, let the fabric dry fully before rolling it back in if it does get wet, and clean it occasionally with mild soapy water rather than harsh chemicals. A cassette design (like the Outsunny) does some of this protective work for you automatically.
Will an awning work in light rain?
Both canopies are water-resistant and will shed light rain, but neither is designed to be left out in heavy or sustained rain or under standing water, which can stress the frame and pool on the fabric.
