A retractable dock shelter is a fabric shelter fixed to the building around a loading bay door, with flexible top and side curtains carried on a sprung or pantograph steel frame. When a trailer reverses in, the frame retracts and the curtains drape against the trailer's sides and roof, closing most of the gap while leaving the full width of the trailer opening clear for loading.
How does this suit sites in Dorset?
For a dock in Dorset where wide pallets need the full trailer opening, a shelter keeps that width clear while still closing the gaps. Retail and e-commerce distribution centres in Dorset with high trailer turnover need tough sprung-frame shelters that recover quickly after each departure.
Third-party logistics sites in Dorset receiving trailers from many hauliers usually need a shelter rather than a seal, because widths and heights vary.
We never ask you to commit before you have a fixed price. A free survey at your Dorset site comes first, followed by a written quote. When the order goes ahead, we plan the installation around your operation, book any out-of-hours working you need and manage the specialist installation engineers on site. The job ends with a full test, a run-through for the people who will use the equipment and a set of handover documents.
How do I size a retractable shelter for my trailers?
Size a retractable shelter to the largest trailer you receive, with a projection deep enough for opened trailer doors and the leveller lip, and curtains that still reach the smallest vehicles. The trailer mix sets almost every dimension.
- Width: wider than the trailer, so the side curtains drape along its sides rather than across the opening.
- Height: high enough for the tallest trailers, with a top curtain deep enough to reach the roof of the lowest.
- Projection: deep enough for the rear doors, folded back along the trailer sides, to sit inside the curtains.
- Curtain cut-outs: vertical slits let the side curtains wrap around hinges and rear fittings without tearing.
- Guide stripes: contrasting stripes on the curtains help drivers centre the trailer.
If your fleet is uniform, a seal may give a tighter fit. Our guide to shelters and seals sets out the trade-offs.
What regulations and permissions apply to a dock shelter?
A dock shelter is work equipment, so it must be suitable and kept in a safe condition, and on some projects planning, building control or landlord consent also needs checking. What applies depends on the nation and the scope of work.
- Equipment duties: PUWER 1998 in Great Britain, and PUWER (Northern Ireland) 1999, require shelters, like other dock equipment, to be suitable, maintained and inspected where deterioration could lead to danger. A damaged frame or loose curtain can strike a driver or vehicle.
- Regulator: HSE in Great Britain and HSENI in Northern Ireland.
- Planning: external structures such as loading houses, canopies or new dock approaches can need planning permission. If a shelter is part of wider external works, we check this at survey.
- Building control: forming a new opening for a door and shelter may need Building Regulations approval in England and Wales, a building warrant in Scotland or building control approval in Northern Ireland.
- Your lease: landlords often require consent for fixings to the building.

Which rules apply in England?
Powered doors and dock equipment installed in England may carry the UKCA or the CE mark, and doors are covered by the product standard BS EN 13241. We hand over the relevant documentation for each item fitted in Dorset. Planning and Building Regulations questions are never assumed either way: we check what applies at survey, so you know before work is booked.
Questions
Which building and safety rules apply to a site in Dorset?
It depends on which UK nation the site is in. England and Wales use Building Regulations approval, Scotland uses building warrants and Northern Ireland uses building control approval from the council. Workplace safety is regulated by HSE in Great Britain and HSENI in Northern Ireland, and energy rules differ between nations. For your site in Dorset, we check what applies at survey and design to it.
Will you deal with building control and planning for a project in Dorset?
We check at survey whether the work is likely to need approval. Forming a new opening or dock pit may need Building Regulations approval, a building warrant or building control approval, depending on the nation, and external structures such as loading houses can need planning permission. Where approval is needed, we explain what is involved, work with your designer or agent, and build it into the programme.
What projection should a dock shelter have?
Projection should be deep enough to clear opened trailer doors and hinges and to suit the leveller lip and bumpers. Shelters are commonly made with projections from around 500 to 1,000 mm, and we recommend a depth once we know your trailers and leveller.
Will a shelter work with curtain-sided trailers?
Yes, retractable shelters suit curtain-siders well, as the side curtains drape along the trailer body. Where curtain-siders are loaded from the rear, the shelter closes the gaps around the sides and roof while leaving the full rear opening clear for forklifts and pallet trucks.
