A dock seal is a set of fabric-covered foam pads fixed to the building around a loading bay door, usually a head pad and two side pads. When a trailer reverses in, its rear end presses into the foam, which compresses to close the gaps around the trailer body. Seals give a very tight fit but work best when the trailers using the bay are a consistent size.
How does this suit sites in Greater London?
A dedicated chilled fleet serving a site in Greater London can be sealed closely with foam pads, at lower cost than fitting an inflatable shelter. Weather-exposed bays in Greater London gain the most from a well-fitted seal, since wind and rain otherwise find every gap around the trailer.
Older seals at docks in Greater London that have been left with split covers can soak up rain, becoming heavy and losing their shape over winter.
We keep the process simple for sites in Greater London. A free survey tells us what the dock needs; a fixed written quote tells you what it will cost and what is included. We then organise the installation, with specialist engineers under our management and a programme agreed around your shifts. Night and weekend work is available by arrangement. Before we leave, the new equipment is tested, demonstrated and handed over with its documentation.
When is a dock seal a better choice than a shelter?
A dock seal is a better choice than a shelter when the trailers using a bay are consistent in size, the dock height suits them, and the tightest practical seal matters. Mixed fleets are usually better served by a shelter.
- Consistent fleets: dedicated vehicles or regular hauliers using the same trailer type.
- Temperature control: chilled or heated buildings where gaps around the trailer are costly.
- Security and hygiene: fewer gaps for pests, dust and unauthorised access during loading.
- Budget: seals cost less than inflatable shelters for a close fit.
The trade-offs are that seals can leave gaps at trailer door hinges, side pads can intrude into the trailer opening if poorly sized, and the covers wear from rubbing. If your trailers vary, compare our retractable dock shelters before deciding, as they leave the full opening clear.
What do workplace transport rules mean for a sealed dock?
A sealed dock still needs safeguards against a trailer leaving early, and the seal, bumpers and other dock equipment must be kept in safe working order. In Great Britain the regulator is HSE; in Northern Ireland it is HSENI.
- Drive-away: HSE workplace transport guidance (HSG136) and the HSE loading factsheet call for safeguards against drivers driving away too early, including traffic lights, vehicle or trailer restraints, or the person in charge keeping keys or paperwork until it is safe.
- Trailer creep: because the trailer is pressed into compressed foam, it can ease forward during forklift loading. Restraints and well-set bumpers help keep it in position.
- Equipment duties: a dock seal forms part of the loading bay's work equipment, so the general duty under PUWER 1998 in Great Britain, or PUWER (Northern Ireland) 1999, to keep equipment suitable and maintained applies.
Torn covers and crushed pads can hide damage to the fixings and wall behind, so seals belong in planned inspections of the dock.

Which rules apply in England?
Workplace safety in England is regulated by HSE. For a loading bay in Greater London, that means doors meeting regulation 18 of the Workplace (Health, Safety and Welfare) Regulations 1992, equipment maintained under PUWER and suitable safeguards against vehicles driving away too early. We check what applies at survey and design the bay accordingly.
Questions
Is VAT included in your guide prices for dock seals?
No. Our customers are businesses, so guide prices exclude VAT, which is added at the standard rate. The same guide range applies in Greater London as everywhere else: for dock seals, it is £1,100 to £2,600 per set, excluding VAT. It covers supply and fit for a typical installation. Your fixed written quote after the free survey shows the net price, the VAT and exactly what is included.
Can you work alongside our main contractor on a new build in Greater London?
Yes. For new warehouses and fit-outs, we can supply and install the dock package as part of a wider project, working to the main contractor's programme, site rules and permits. We will need drawings, dock levels and the programme, and we coordinate pit details, power supplies and door openings with the relevant trades before installation begins.
How can I tell if seal projection is wrong?
Look at the pads with a trailer docked. Daylight around the head or sides suggests too little compression, while pads squashed flat or bulging around the trailer suggest too much. Worn bumpers are a common cause, and both can be checked at a planned service.
Do trailer doors need to be opened before docking against a seal?
Yes, the rear doors are opened and folded back before the trailer reverses onto a seal, so the pads press against the rear of the trailer rather than the doors. Gaps can remain at the door hinges, which is a known limitation of seals compared with shelters.
