Some source checks are outside our review interval. Treat the quoted prices and terms as dated references, not current offers. Verify them with the linked sources before choosing; travel requirements also need a fresh official check.

At a glance
The five dated examples run from £42.99 to £810.00 before separately stated extras. That spread covers unlike products, not a cheapest or safest ranking. Vehicle fit, anchoring and the exact boundary of any test claim matter alongside price.
Exact UK manufacturer or specialist-retailer pages checked 11 September 2026. CVP has not installed, driven with or crash-tested these crates. Dimensions do not guarantee fit, availability can change, and test statements remain attributed to their named source.
Compare dog car crates by boot dimensions
Filter five exact models by fit evidence and maximum external dimensions. The filter does not rotate crates. For an adjustable model, depth uses its published minimum setting and the card shows the full range; neither result guarantees vehicle fit.

Thule Allax XS
Aluminium / Black 770000

The page displayed a notify-me state when checked, so this is not presented as currently orderable.

- Anchoring evidence
- Manufacturer states tension bands fasten the crate while driving; follow the exact crate and vehicle instructions.

- Source-stated testing

- Included parts stated
- Internal anti-slip matting; Removable divider; Rear escape door; Top storage tray

A boot crate is not a household crate or car seat
This comparison is limited to rigid crates designed for a vehicle boot. Household folding crates do not become vehicle restraints merely because they fit in a boot, while boosters, tether harnesses and carrier bases use different installation and fit checks.
Measure the boot opening and usable space
External width, depth and height are kept in the source’s stated orientation and are never rotated by the filter. Check the opening as well as the floor space, then account for the loading sill, rear-seat angle and the clearance needed to operate every required door. For an adjustable crate, the depth filter uses its stated minimum setting and the result shows the full adjustment range; that is still not a fit guarantee.
Sources: Cozy Pet · DT Boxes · Travelling With Pets · Thule · TransK9Keep anchoring, anti-slip parts and escape access separate
A tray, sloping side or anti-slip mat is not evidence of anchoring. The 4pets page states tie-down straps are included; Thule describes tension bands; TransK9 prices an anchorage kit separately. The Cozy Pet and selected DT Box pages do not state an anchoring method. Rear escape access also varies by exact model and option.
Sources: Cozy Pet · DT Boxes · Travelling With Pets · Thule · TransK9Testing statements are not interchangeable ratings
Thule identifies a TÜV SÜD certificate and named test methods. The 4pets retailer states TÜV SÜD testing and approval. DT Boxes and TransK9 state independent testing but do not show a protocol or numerical result on the exact pages checked, while Cozy Pet CDC03 states no test method. These records are source claims, not CVP testing or a promise that injury cannot occur.

Worked arithmetic example
Illustration only: a £100 delivered product plus 6 replacement packs at £5 totals £130. This is not a product offer or lifespan estimate.
Method: multiply each price by its quantity, round each line to the nearest penny, then add. No inflation or unentered charges are assumed.
