Used site cabins do not have to come from a specialist dealer at refurbished-unit prices. Enviro Stock supplies used site cabins, welfare units, portable offices, canteen and drying blocks and toilet blocks across the UK, all sourced from UK businesses clearing surplus site equipment. You can request condition and paperwork information on any lot before you commit, so buying remotely is straightforward wherever you are in the country.

Enviro Stock sources static site cabins, welfare units, portable and modular offices, canteen and drying room blocks, toilet blocks, anti-vandal units and static storage containers. These are genuine used units that come to market when a UK business clears surplus site equipment, listed at clearance pricing rather than refurbished-dealer or new-manufacturer rates.
This route exists because of how construction firms, contractors and plant hire companies operate. Site fleets get rationalised when contracts end, when a business restructures, or when a unit ages out of the hire pool. At that point the accommodation enters the clearance market as a genuine commercial disposal. You get a real used unit at below-replacement pricing, and because there is no dealer refurbishment margin built in, the grading and paperwork on each lot do more of the work than a showroom would.
Because almost every buyer here is purchasing remotely and nationally, each lot is graded and listed so you can assess its condition before committing. You can read how we grade stock for more on how we assess and document condition. Site accommodation often clears alongside other plant and equipment, so it is worth browsing our wider industrial assets category too. If this is your first time buying clearance stock, our beginner's guide to buying clearance stock pallets explains how the process works.
Stock changes as lots clear, but the site and welfare unit types behind this category are:
This category covers static units only. Mobile towable welfare vans and self-powered welfare vehicles are a separate product class and are not listed here.
Used site cabins and welfare units come from UK businesses clearing their site fleet, so condition and configuration vary by lot. Because most buyers purchase remotely, the way to assess a unit is to ask us for the condition grading, the service records and any electrical certificates before you commit.
Start with condition and grading. Every lot is graded and documented, covering the roof, external cladding, internal fixtures, flooring, windows and door operation, along with the dimensions and weight you will need for delivery access. You can see how we grade stock, and for any specific unit you can ask us for the full condition notes or manifest so you have a clear picture before deciding.
For welfare units and anti-vandal offices, the paperwork matters as much as the fabric. Portable and transportable site units are classified under Section 717 of BS 7671, which sets out how their electrical installations should be certified and inspected, including an Electrical Installation Certificate that identifies the specific unit and a minimum annual inspection by a competent person. Rather than arranging any of this yourself, ask us for the most recent electrical inspection documentation, such as an EIC or EICR, along with the PAT records for any portable appliances supplied with the unit. Where a unit runs on an on-board generator instead of mains power, ask us for the generator service record and the current hour meter reading, which together show how hard the unit has worked and how well it has been maintained.
It helps to know what a welfare unit is designed to do. Under Schedule 2 of the Construction (Design and Management) Regulations 2015, a construction site must provide welfare facilities including toilets, washing facilities, drinking water, changing and rest areas, and the HSE's welfare guidance confirms these should be in place from the first day of a project. A purpose-built welfare unit bundles those facilities into a single portable structure.
Enviro Stock sources site offices and portable offices, welfare units, canteen and drying blocks, portable toilet blocks, anti-vandal units, modular buildings and static storage containers. Because stock is clearance-sourced, availability changes as lots clear from commercial disposals. Browse the current listings to see what is in stock today, or contact us to ask about incoming lots.
Every lot is graded and documented, so you can see the condition grade in the listing itself. For any unit you are considering, ask us for the full condition notes or manifest, which cover the roof, cladding, internal fixtures, flooring and doors. You can read how we grade stock for more on how we assess each lot, all without needing to travel to view it.
Yes. For welfare units and anti-vandal offices, ask us for the service record, the generator hours where a unit is generator-powered, and any electrical inspection documentation such as an EIC or EICR. We provide these on request so you can assess the paperwork before committing, rather than needing to arrange any checks yourself.
Yes. Enviro Stock can arrange delivery to you rather than leaving you to organise your own transport or collection. Delivery specifics depend on the unit size, its weight and your site access, so contact us to confirm arrangements for a particular lot.
A site cabin is the general term for any portable or modular building used on site, which might be a plain office, a store or a rest space. A welfare unit is a specific type of site cabin that includes the welfare facilities a site needs, such as toilets, washing facilities, a rest and canteen area and often a drying room. Both types pass through Enviro Stock depending on the clearance lot, so check the listing or ask us which a given unit is.
Yes, provided the unit has been maintained and its certificates are in order. Because you are buying remotely, ask us for the service history, the condition documentation and any electrical inspection records before purchasing a unit for active site deployment. With that paperwork in hand you can decide with confidence whether a specific unit suits your site.
If you have surplus site cabins or welfare units to sell, our sister business Enviro Clear buys stock directly from UK businesses. Visit enviro-clear.co.uk to find out more.
