Terms of Service.
The contract between SteelEstim8 and you when you subscribe to any product in the SteelEstim8 family. Plain English first, with the structure a UK contract needs.
Last updated: 2 May 2026
1. The parties
These terms (the "Terms") form a binding contract
between SteelEstim8 (referred to as
"we", "us", "our"), the operator of the marketing
site at steelestim8.co.uk and the application(s) in the
SteelEstim8 family, and the customer signing up for a subscription
(referred to as "you", "your").
By starting a subscription on any product in the SteelEstim8 family
— including by completing the sign-up flow at
steelestim8.co.uk/start — you agree to be bound by
these Terms.
2. The service
We provide a family of web-based estimating and engineering applications for UK steel fabricators (collectively, the "Service"). The current and planned products in the family are:
- SteelEstim8 — portal-frame estimating with full GA drawings, rate library, quote PDF generation, dashboard. Currently shipping.
- MezzEstim8 — mezzanine quoting with BS 5950 section sizing, live 3D viewer, branded buyer proposal. Currently in private alpha.
- LoadEstim8 — portal-frame Eurocode 3 (BS EN 1993-1-1) member sizing with calc pack output. Currently in pre-launch.
- RailEstim8 — handrail and balustrade quoting with Part K / BS 6180 / BS 5395 compliance warnings. Currently in pre-launch.
- Future products (e.g. stairs, mobile modules) added to the family from time to time, each with their own subscription price or included in the Family bundle (see section 4).
You access the Service over the internet using a modern browser. The
Service includes the functionality described on the product pages of
steelestim8.co.uk from time to time. We may add features
within a product; we will not remove basic functionality already
included in your subscription without notice.
3. Subscription term
Subscriptions are monthly, with no fixed term. Your subscription begins on the date your first card payment is collected and continues on a rolling monthly basis until you cancel. There is no minimum contract length and no early-termination fee.
You can cancel at any time from your account portal or by writing to info@steelestim8.com. Cancellation takes effect at the end of the current billing month; no refund is given for the part-month already paid, but no further charges are taken and your access continues until that billing month ends.
4. Pricing & payment
Each product in the SteelEstim8 family is sold as its own monthly subscription. You can also subscribe to the Family bundle, which gives you access to every product in the family for one combined price (10% off the individual total).
Per-product pricing (monthly, incl. VAT)
- SteelEstim8: £160 / month
- MezzEstim8: £85 / month
- LoadEstim8: £60 / month
- RailEstim8: £39 / month
Family bundle
- £309 / month, incl. VAT — access to every product currently shipping in the SteelEstim8 family.
- New products added to the family during your subscription are included in your bundle at no additional cost.
- Saving against the individual total (£344/month for the four current products) is approximately 10%.
- The bundle price may be adjusted as additional products ship into the family. We will give at least 30 days' notice in writing of any bundle price change, and you may cancel before the new price takes effect.
Common terms
- Payment: recurring monthly card payment via Stripe Checkout. The card you authorise at sign-up is charged on the same date each month, automatically. Apple Pay and Google Pay also supported. We never see or store your raw card details.
- VAT: all prices listed are inclusive of UK VAT at the standard rate. A VAT invoice is issued for every payment.
- Switching plans: you can switch between individual product subscriptions and the Family bundle at any time by emailing info@steelestim8.com. The new rate applies from the next billing cycle; no pro-rata adjustment is made for the part-month already paid.
- Pilot programme: we offer free pilot access to a limited number of UK fabricators in exchange for honest feedback and a 30-minute monthly call. Pilot access is at our discretion, subject to availability, and granted by separate written agreement. Pilot access has no fixed duration and may be ended by either party at any time.
- Founder advisory: customers signing up before 31 December 2026 are entitled to one 30-minute video call with the founder per calendar month for the first six (6) months of their subscription, scheduled at mutually convenient times. Calls focus on product feedback. Missed calls may be rescheduled subject to availability but are not refundable, and unused calls do not roll over. The benefit is non-transferable and ends after month six (6) or on cancellation, whichever is sooner.
- Price holds: the price you signed up at is held for as long as your subscription remains active without cancellation. If we increase a product price, existing subscribers stay on their original price unless they cancel and re-subscribe (in which case the current price applies).
- Late payments: if a card charge fails, we will retry the collection. If two consecutive retries fail and the balance remains unpaid for 14 days, we may suspend access until the balance is cleared. Suspension does not pause the billing cycle.
Payment processing is handled by Stripe Payments UK Ltd on PCI-compliant infrastructure. The card you authorise at sign-up via Stripe Checkout is stored by Stripe and charged automatically on the same date each month.
5. Cancellation
You may cancel your subscription at any time, for any reason, with no fee and no minimum term. To cancel:
- Use the cancel option in your account portal, or
- Email info@steelestim8.com with the email address on your subscription.
Cancellation takes effect at the end of the current billing month. The part-month already paid is not refunded; access continues until the end of that billing month, then ceases. We retain Customer Data for 30 days after cancellation to allow export (see section 8).
If you cancel and later re-subscribe, the current price at that time applies (see section 4 — price holds only continue while a subscription remains active).
6. Termination by us
We may terminate this contract immediately (and without further liability to you, save to refund any pre-paid period not used) if:
- You materially breach these Terms and have not remedied the breach within 30 days of written notice;
- You become insolvent, enter administration, or are unable to pay debts as they fall due;
- You use the Service in breach of section 7 (Acceptable use).
7. Acceptable use
You agree not to:
- Reverse engineer, decompile, or attempt to extract the source code of the Service;
- Use the Service to provide a competing estimating, quoting or member-sizing service to third parties;
- Resell, sublicense, or otherwise transfer access to the Service;
- Upload data you do not have the right to upload, or data containing malware;
- Use the Service to violate UK law (including UK GDPR), or to facilitate fraud.
8. Your data
You retain ownership of all data you input into the Service (the "Customer Data") — including rates, estimates, quote PDFs, company details, GA drawings, mezzanine designs, member-sizing calc packs, and balustrade quotes. We process Customer Data only to provide the Service to you, and as described in our Privacy Policy.
You can export your Customer Data at any time. On termination (whether by you, by us, or otherwise), we will retain Customer Data for 30 days to allow you to export it, then permanently delete it from active systems within 90 days. Backup copies expire on their normal cycle (currently within 12 months).
9. Liability
Nothing in these Terms limits or excludes liability for: death or personal injury caused by negligence; fraud or fraudulent misrepresentation; or any liability that cannot lawfully be excluded under English law.
Subject to the paragraph above, our total aggregate liability under or in connection with these Terms in any 12-month period shall not exceed the fees paid by you in the 12 months immediately preceding the event giving rise to the claim. Neither party shall be liable for indirect or consequential losses, loss of profit, loss of business, or loss of anticipated savings.
The Service is provided "as is". We make no warranty that the Service will be uninterrupted or error-free. Estimates, GA drawings, mezzanine proposals, member-sizing calc packs and balustrade quotes produced by the Service are indicative only — they are not engineering certifications and must be reviewed and signed off by a qualified structural engineer or other appropriate professional before use on a real project.
10. Intellectual property
We own (or are licensed to use) all intellectual property rights in the Service, including the code, designs, and brand assets (the SteelEstim8, MezzEstim8, LoadEstim8, RailEstim8 names and the S8 / M8 / L8 / R8 marks). You receive a non-exclusive, non-transferable, worldwide right to access and use the Service during your subscription term for your internal business purposes.
11. Confidentiality
Each party agrees to keep confidential the non-public information of the other shared in connection with this contract, and to use it only for the purposes of performing this contract.
12. Changes to these Terms
We may update these Terms from time to time. If we make a material change that adversely affects you, we will give at least 30 days' notice by email to your registered address. Continued use of the Service after that period means you accept the updated Terms. If you do not accept the change, you may cancel as set out in section 5 before the change takes effect.
13. Governing law & disputes
These Terms and any dispute arising from them are governed by the laws of England and Wales. The courts of England and Wales have exclusive jurisdiction.
Before issuing court proceedings, the parties agree to attempt to resolve any dispute in good faith by direct discussion, then by mediation under the Centre for Effective Dispute Resolution (CEDR) Model Mediation Procedure if direct discussion does not resolve it within 30 days.
14. General
- Entire agreement: these Terms, together with the Privacy Policy and any order confirmation, form the entire agreement between us.
- Assignment: you may not assign this contract without our written consent. We may assign it to a successor entity.
- Severability: if any provision is held unenforceable, the remainder of these Terms continue in force.
- Notices: notices to us must be sent to info@steelestim8.com. Notices to you will be sent to your registered email address.
