What we convert containers into
Every conversion starts as a steel job: openings cut and framed, doors and shutters hung, internal steelwork fitted and the unit painted to your spec. These are the commercial conversions that come through the workshop most.
| Conversion | Steelwork involved | Who orders it |
|---|---|---|
| Plant and equipment rooms | Side openings, louvre frames, equipment bases, cable entries | M&E and energy contractors |
| Battery and generator containers | Mounting frames, access doors, ventilation openings | Energy and battery installers |
| Secure stores | Roller shutters or double doors, shelving frames, lock boxes | Contractors, estates, logistics sites |
| Workshops and site units | Personnel doors, windows, partitions, linked units | Construction and civils contractors |
| Linked and stacked buildings | Units joined, stacked and braced, stairs and decks | Multi-unit site buildings |
Built so the box stays square
A container gets its strength from its corrugated walls and rails. Cut a wall without framing it and the unit can rack when it's lifted. Every opening we cut is framed in welded box section tied into the top and bottom rails, so doors keep closing true after the unit has been craned onto site.

Getting work to and from the yard
The workshop is at Moreteyne Farm, Wood End, Marston Moretaine (MK43 0NY), just off the A421 between Bedford and Milton Keynes. Most work comes from within 40 miles: Milton Keynes, Bedford, Luton, Dunstable, Leighton Buzzard, Northampton, Wellingborough, Kettering, St Neots, Cambridge, Huntingdon, St Albans, Stevenage, Hitchin and Aylesbury. We quote anywhere within about 100 miles; see areas we serve.
We send an engineer to your site to see the job and organise delivery of the finished units through our logistics partners. With everything made in-house, that often works out cheaper than a local converter.
Frequently asked questions
How much does a container conversion cost?
Recent units have run from about £3,400 to £6,800 each, net of VAT, depending on the openings, internal steelwork and finish. The quote is itemised per unit.
Can you convert several containers at once?
Yes. Capacity is around 8 units a week, more when an order needs it, and 12 have gone through in a single week. Multi-unit orders are paid in stages.
Do you supply the containers?
Either way works. We convert units you already own, or source new or used containers for the job and include them in the quote.
Do you fit electrics or insulation?
Our work is the steel: openings, framing, doors, shutters, internal steelwork, decks and paint. Tell us at quote stage if you need electrics or lining and we'll say straight whether we can include it.
Do you deliver the finished containers?
Yes. We organise delivery to your site through our logistics partners and agree the drop with you, including what lifting is on site.
