If your existing hutch is good but the exercise space isn’t enough, you don’t need to replace the whole setup — you need an extension run. These picks are designed to attach to an existing hutch or function as a permanent add-on exercise area. All rated out of 10.
| Rank | Extension | Rating | Price | Best for |
|---|---|---|---|---|
| 1 | Canterbury XL 7.7ft Run | 9.2 | ~£80 | Bonded pairs, major upgrade |
| 2 | Chartwell 4ft Run | 8.4 | ~£55 | Chartwell owners, matched look |
| 3 | Deuba Steel Run | 7.6 | ~£45 | Portable, rot-proof, moveable |
7.7ft of galvanised folding run is as much space as most UK gardens can accommodate as an extension, and the Canterbury’s hinge quality is what separates it from cheaper alternatives that buckle after a season. The solid hinges fold the whole structure flat for storage — a meaningful feature when you need to move it, jet-wash the hutch, or store it for winter. Pairs naturally with Kendal and other quality hutches that have a door on the front face.
Pros: 7.7ft of run space · Solid fold-flat hinges · Galvanised — no rust
Cons: Large footprint when open · Check door alignment with your hutch
Dimensions: 235 × 120 × 48 cm

The matched companion to the Chartwell hutch range — but it attaches neatly to most flat-fronted hutches, not just Chartwell models. The Hutch Company’s build quality means the mesh gauge and frame joints are a step above generic budget runs at a similar price. 4ft is a practical exercise length when paired with a properly sized hutch. Best for owners who want a tidy, matched aesthetic and a run that will outlast the hutch it attaches to.
Pros: Hutch Company build quality · Pairs with most flat-fronted hutches · Tidy aesthetic
Cons: 4ft is the minimum we’d recommend for daily exercise · Premium price for size
Steel frame makes this genuinely rot-proof and far lighter to reposition daily than wooden runs. The included sun cover is a practical addition that saves a separate purchase. Best used as a movable daytime grazing area rather than a permanently attached extension — the open enclosure format is not a complete fox barrier without additional anchoring on lawn.
Pros: Lightweight steel · Rot-proof · Sun cover included · Folds flat
Cons: Open enclosure — anchor securely · Not for unsupervised use with determined foxes
Dimensions: 94 × 53 × 5 cm (folded)

Most extensions attach via a clip or hook system to the hutch’s front-facing door opening. For a permanent connection, cable ties through both frames add security. The key measurement to check before buying is the width of your hutch’s door opening versus the run’s access point — mismatches mean rabbits can squeeze through gaps.
Ratings are out of 10.0, based on: run size, mesh quality, ease of attachment, weather resistance and value.
