Buying direct
Why this costs what it costs
1
You are buying from the source
We design the Expanda range and supply it direct. There is no distributor margin stacked on top, because there is no distributor.
2
The original, not a copy
The Expanda range has been made here since 1986. Copies exist. They are not built to the same specification and they do not last as long.
3
Nothing is added afterwards
The price you see excludes VAT and delivery, and delivery is quoted from your postcode before you pay. There is no other charge.
4
The people on the phone made it
Ring with a technical question and you will speak to someone who knows how the unit goes together.

Before you order
Questions people ask us
How quickly can I have one?
Standard delivery runs on a rotational schedule by postcode area and is typically around four weeks from order. If you need it sooner we offer delivery within three days, within 48 hours, or same day within 24 hours for a surcharge, chosen at checkout.
Do I need a crane or a forklift?
No. Flat-pack units arrive in panels and are assembled on site by two people using ordinary hand tools. There is no crane hire and no hardstanding requirement.
Is delivery included in the price?
No — delivery is priced separately from your postcode and shown in full before you pay. There is nothing added afterwards.
Are you a designer or a reseller?
Yes. Every unit is made from our base in Lingfield, Surrey. You are buying from the source, so there is no margin stacked on top and technical questions get answered properly.
Can I buy on account?
Yes, for established trade customers. Ring 01342 830041 and we will set one up.
What if I need a size that is not listed?
We design the range, so bespoke sizes and specifications are routine. Ring us and we will price it.
