Debt Recovery Fee

Amounts £1 000.00 to £9 999.99 = £70

Amounts exceeding £10 000.00 = £100



Once your deposit has been received, we shall issue Approval Drawings for you to sign off on. It is the responsibility of the Client to check the individual features and positions of features on their original plans against the Approval Drawings. Changes or amendments made after approval drawings have been confirmed, WILL incur charges for redrawing. The Client will be responsible for said charges. Additionally, significant changes to the building design may lead to a revised quote price. The Client agrees to accept any material change in price because of re-draw or re-design.


Our standard turn-around time for delivery is 3-4 weeks however Clients are strongly advised to check our website for the latest delivery times. We will advise you of a “week commencing” delivery date once your approval drawings have been signed off; and a specific delivery date closer to the “week commencing”. It is not possible to reschedule delivery inside of a week prior to the arranged delivery date so if you need to delay delivery beyond the advised time please contact us ASAP.

Delivery is to the front of the property only unless there is sufficient area for the delivery truck to turn around on your property. Delivery does not include off-load or laying down of materials and Clients should assume they are responsible for this. Clients requiring assisted off-load should book this as an optional, chargeable extra at the time of order.

If a delivery cannot be made for whatever reason the Client agrees to pay any demurrage, storage and re-delivery charges imposed by the transportation company. Castle Steel Buildings Limited or their subcontractors shall not be responsible for any costs incurred or loss of trade resulting from an aborted delivery. Please complete the Delivery Call Off Sheet at the end of this quote, scan or photograph it and email it to us.


A steel building from us cannot be fastened to soft ground, soil, gravel, resin-bonded surfaces or tarmac. Your steel building will require a suitable base onto which it can be bolted and built, ideally a concrete pad with mesh and individual pillar points to support the columns.

The client responsible for ensuring a suitable base is prepared before building installation can begin, however we can provided you with some generic advice. This advice comes free of charge with any order.

If, in the judgment of our subcontracted installers, a base is not suitable we reserve the right to postpone the installation and charge for any additional costs incurred.


Clients are responsible for ensuring that all structural calculations and planning permissions are in place before your kit is placed into manufacture.  Changes to kits once in production are expensive and delay delivery. We can provide a structural calculations pack for Building Control on request. This is chargeable prior to an order but we will supply it freely

Please note we do not provide specific planning permission advice or consultancy. The client is responsible for planning permission applications.

Generic advice on planning regulations, including the score of permitted development, can be found on our website.


Please note that we offer an optional installation price from a recommended and experienced installer.

As such, we are not considered as the Principal Contractor for the installation of your building. If we are not advised as to who is the principal contractor, we will assume this role is being undertaken by the Client (yourselves).

The Principal Contractors role is set out in CDM regulations (2015) and such things as welfare facilities, site security, physical barriers, site signage and the overall safety of all trades, client personnel and the public is the responsibility of the Principal Contractor on the site.

Additionally, power should be supplied by Client and all wiring/electrical connections for powered roller doors should be done by others with the appropriate qualifications. Suitable access and ground conditions to and around the proposed building is needed for the plant and equipment used during construction. This generally requires a clear 2-3 meters around all elevations of the building but in some cases as little as 1 meter can be acceptable. You will need to discuss this in detail with your installer.

There will also need to be access onto the slab for the installation plant; therefore, a suitable ramp onto said slab may be required depending on its dimensions. We are not responsible for the removal of waste or surplus materials. Construction waste should be removed from site by others, and we recommend a skip is made available at the time of installation to avoid housekeeping issues during or towards the end of construction.

Please ensure the site is free of obstructions and that surfaces are level, clean and fit for purpose. We cannot be held responsible for damage caused to materials due to site conditions.

Site inductions will be up to 60 minutes long at the start of the project.

There shall be no out of hours or weekend work unless agreed with the installation team prior.
