Top tips
Hiring a motor homes, without the regret.
Four moves that separate a smooth job from a nightmare.
Habitation check is the equivalent of MOT.
Annual habitation check (interior systems — gas, water, electric, damp, ventilation) is what insurers and warranty providers expect. Don't skip it.
AWS-approved workshops only.
Approved Workshop Scheme (AWS) garages are NCC-vetted, audited annually. Independent garages may be cheap but invalidate warranty.
Check for damp ingress.
Damp at floor seams or rooflights is the #1 motorhome killer. Annual habitation check catches it before £10k repairs.
Gas-only on bottled LPG.
Motorhome gas appliances run on bottled LPG, not mains gas. The Gas Safe registration is different (LPG-Cat 2) — confirm.
