ASIC Hosting Due Diligence Checklist for UK Buyers

ASIC hosting due diligence should be completed before you pay for or send valuable mining hardware to a third-party facility.

ASIC hosting moves power, cooling and day-to-day operation to a specialist site, but it also puts valuable hardware outside your direct control. UK buyers should verify the legal operator, physical facility, complete price, service levels, insurance, monitoring, repair process, ownership records and exit route before paying for or shipping equipment.

Why ASIC hosting needs proper due diligence

Reassess ASIC hosting due diligence whenever network conditions, firmware, tariffs or official guidance changes.

Hosting can solve the difficult parts of running an industrial ASIC: continuous power, cooling, connectivity, noise and onsite fault response. The trade-off is control. Your machine may be thousands of miles away while somebody else controls access, billing, maintenance and release. Due diligence means collecting evidence that the legal entity, physical operation and written obligations match. This is commercial guidance, not legal, tax or insurance advice; obtain professional advice for a material deployment.

Verify the operator and the physical site

When reviewing ASIC hosting due diligence, separate measured facts from forecasts so the result can be reproduced.

Start with the exact legal name, registration number, address and contracting entity. Companies House provides UK company details, officers, filings, charges and insolvency information. It publishes filed information, however; it does not guarantee every claim or the company's financial strength. Establish who operates the site. A reseller may use a separate facility owner or overseas subcontractor. Ask who holds the hardware, invoices you, owes the service obligation and releases the miners. The contract should explain every link. Request the country and a suitably specific site description. Security may prevent publication of a full address, but the provider should evidence the site and its control of capacity. A live video call, time-stamped footage, documents and a pilot beat stock photographs.

Break down the complete hosting price

A low rate per kWh means little until you know what it includes. Get a schedule covering energy, currency, tax, deposit, siting, cooling, minimum charges, management, repairs, parts, shipping and withdrawal. Ask whether consumption is metered, rated or fixed. For a floating price, identify the index, adjustment interval and notice. Confirm when billing begins and how idle machines, commissioning delays and downtime are treated.

Inspect the technical operation

Confirm support for the exact model, algorithm, voltage, connector, power and cooling method. For hydro or immersion, check flow, fluid or coolant requirements, heat rejection, leak response and commissioning. For air cooling, ask about recirculation, filtration and seasonal conditions. Get the target uptime and its definition. Check exclusions for maintenance, curtailment, pool outages, customer settings and machine faults; how downtime is measured; when credits apply; and whether charges continue. Understand monitoring, alerts and pool access. Nobody needs your wallet seed phrase. Also ask who diagnoses faults, which spares are onsite, what spending needs approval and when a unit leaves for repair.

Read the contract, ownership and exit terms

The agreement should confirm that the identified hardware remains yours unless the deal expressly says otherwise. Keep invoices, serials, photographs, test reports and delivery records. 'Ten miners' is weaker evidence than ten recorded models and serials. Read the term, renewal, suspension, termination and notice rules. Check whether the host can retain or sell hardware for unpaid bills and how disputes work. Seek legal advice on unclear or foreign-law provisions. Make the exit practical: authorised requester, identity check, de-racking time, condition report, packaging, coolant draining and insured freight. Address site closure, insolvency and the end of any subcontracting arrangement.

Evidence worth requesting before payment

• Legal entity details and a contract issued by that entity.
• Evidence of the operating site and the provider's right to place equipment there.
• A written rate card showing all recurring and one-off charges.
• Sample invoice and explanation of the energy measurement method.
• Uptime definition, exclusions, curtailment policy and service-credit process.
• Security, access-control, incident, fire and electrical maintenance overview.
• Insurance summary stating whose equipment is covered, for which events and subject to what excesses or exclusions.
• Monitoring demonstration and a sample machine performance report.
• Repair workflow, approval limit, labour rate and common-parts availability.
• Serial-number inventory, intake inspection and release procedure.

Some documents are sensitive. Refusing to publish a detailed electrical diagram is not itself suspicious; refusing all credible evidence of the site, contract or custody is.

Hosting red flags

Walk away from guaranteed returns, pressure for immediate irreversible payment, seed-phrase requests, blank contracting entities and claims with no credible site evidence. Copied photographs, inconsistent addresses and payment to an unrelated individual are serious warnings. Also challenge unclear curtailment, hidden fees, no serial records, no repair approvals, no hardware-return route and a long term without a service standard.

Final pre-deployment checklist

• Operator, site owner and contracting entity identified.
• Company, officers, filings and trading contact independently checked.
• Exact miners and serial-record process agreed.
• Full price, billing formula, taxes and currency documented.
• Power and cooling compatibility confirmed for the exact model.
• Uptime, exclusions, monitoring and curtailment understood.
• Security, insurance, electrical safety and fire controls evidenced.
• Repairs, firmware authority and spending approvals agreed.
• Term, termination, disputes and hardware-return process reviewed.
• Small pilot completed where the scale justifies it.

Conclusion

ASIC hosting should reduce operational friction, not replace it with uncertainty. Verify who has your equipment, where it will run, how every charge is calculated and how you get the machines back. Demand sensible evidence, keep a serialised ownership record and put performance, repairs and exit terms in writing. The strongest hosting offer is not simply the lowest advertised kWh rate; it is the one whose infrastructure, people, contract and economics still make sense after scrutiny.

Frequently asked questions

Does a Companies House listing prove an ASIC host is legitimate?

No. It confirms filed company information and is an important starting check, but Companies House itself notes that it does not verify the accuracy of all information filed. Check the operation, contract, site and payment details separately.

Should the host insure my ASIC miners?

Do not assume so. Ask for the scope, insured party, limits, excesses and exclusions in writing, then confirm with your own broker whether you need additional cover.

What uptime should a host guarantee?

There is no universal figure. Compare the stated target together with its exclusions, measurement method and remedies. A high number with broad exclusions can offer less protection than a lower but clearly defined service level.

Can an overseas facility be suitable for a UK buyer?

Yes, but add jurisdiction, currency, VAT or duties, customs, insured shipping and practical hardware recovery to the assessment. Obtain professional advice where the value or contract term is material.
