Terms & Conditions
Last updated: 11 August 2026
This website is operated by Rentlens Technologies Ltd, a company registered in England & Wales (company number 17361889), registered office 5 Southerton Road, London, W6 0PJ. In these terms, "we", "us" and "our" refer to Rentlens Technologies Ltd, and "you" means the person or organisation engaging us. Contact: [email protected] · +44 7480 251 242.
1. What these terms cover
These terms govern your use of this website and the services we provide. They apply alongside any written proposal, statement of work or order form we agree with you. Where a signed proposal or statement of work says something different, that document takes precedence over these terms for that engagement.
2. The services we offer
We provide software development and related technical services, namely:
- discovery and technical scoping, ending in a written specification and a fixed quote;
- web application design and development;
- mobile application development for iOS and Android;
- API and systems integration work;
- cloud infrastructure and deployment setup;
- ongoing support and maintenance under a monthly agreement;
- fractional CTO and technical advisory work, charged by the day.
What is not included. Unless a proposal says otherwise, we do not supply third-party licences, hosting, domain registration, cloud consumption charges, paid APIs, stock imagery, marketing services, content writing, or ongoing support after the handover period. We do not guarantee any commercial outcome, search ranking, revenue figure or user number arising from software we build.
3. How to commission work
- You contact us through the enquiry form on this website, by email or by telephone.
- We discuss the work and, where it is a fit, issue a written proposal or statement of work setting out scope, timeline, price and assumptions.
- A contract is formed only when you accept that proposal in writing (including by email) and, where a deposit is required, we receive it. Nothing on this website is an offer capable of acceptance, and submitting the enquiry form does not create a contract.
We may decline work. We hold a limited number of projects at a time, and where we cannot start we will tell you the earliest date we can.
4. Prices and quotes
The figures shown on this website are indicative starting prices for a London engagement and are not a quote. They exclude VAT. Your price is the figure in your written proposal.
Written quotes are valid for 30 days from the date of issue. A quote is based on the scope described in it. If you change the scope, or if an assumption stated in the proposal turns out not to hold, we will tell you the effect on price and timeline in writing before doing the additional work. Work outside an agreed scope is charged at our then-current day rate.
5. Payment terms
| Engagement | Terms |
|---|---|
| Discovery and scoping | Payable in full before the engagement begins |
| Build projects | A deposit of 30% on acceptance, the balance invoiced against agreed milestones |
| Support and maintenance | Invoiced monthly in advance |
| Advisory work by the day | Invoiced monthly in arrears |
Invoices are payable within 14 days of the invoice date by bank transfer to the account shown on the invoice. All amounts are in pounds sterling and exclude VAT, which is added at the prevailing rate where chargeable.
Where an invoice is a business-to-business debt and remains unpaid after the due date, we may charge statutory interest and compensation under the Late Payment of Commercial Debts (Interest) Act 1998, and may suspend work on notice until payment is received.
6. Delivery, and what we need from you
Timelines are set out in the proposal and are estimates given in good faith. Delivery depends on you providing, promptly: content, access credentials, decisions, feedback within agreed review windows, and any third-party accounts the project needs. Where a delay is caused by material or decisions we are waiting on, timelines and milestone dates move accordingly and we will tell you.
We work in two-week cycles and demonstrate working software at the end of each one. Where we are running late for reasons within our control, we will tell you as soon as we know, and we will agree a revised date with you.
7. Cancellation
If you are a consumer
If you are an individual contracting outside your trade, business, craft or profession, and the contract was concluded at a distance or away from our premises, you have the right to cancel within 14 days of the day the contract was made, under the Consumer Contracts (Information, Cancellation and Additional Charges) Regulations 2013. You do not need to give a reason. To cancel, email [email protected] with a clear statement that you are cancelling.
If you asked us in writing to begin work during that 14-day period, you must pay for the work performed up to the point you cancel, in proportion to the total contract price. If the service has been fully performed within the 14 days at your express request, and you acknowledged that you would lose the right to cancel on full performance, the right to cancel no longer applies.
If you are a business
Either party may terminate an engagement on 30 days' written notice. On termination you pay for all work completed and any non-cancellable commitments we have made on your instruction. Deposits cover reserved capacity and are non-refundable once work has started.
Support agreements
Monthly support agreements run month to month and either party may end them with 30 days' written notice, effective at the end of a paid month.
8. Refunds
If we have not started work and you cancel, we refund any sum you have paid in full, within 14 days of the cancellation.
If we have started, we refund any amount you have paid that exceeds the value of the work performed and the commitments made, within 14 days.
If a deliverable does not conform to the agreed written specification, tell us within 30 days of delivery and we will correct it at our cost. Where we cannot correct it within a reasonable time, you may have a price reduction or a refund of the amount attributable to that deliverable. Nothing here removes your statutory rights under the Consumer Rights Act 2015, which include the right to services carried out with reasonable care and skill.
Refunds are made by the same method as the original payment. We do not refund third-party costs we have already paid on your behalf, such as licences, cloud consumption or app-store fees.
9. Intellectual property
We retain ownership of all deliverables until we have received payment in full for the engagement. On full payment, we assign to you the intellectual property rights in the bespoke source code, designs and documentation created specifically for you under that engagement.
We keep ownership of our pre-existing tools, libraries, templates, know-how and generic components, and of anything we develop that is not specific to your project. On full payment we grant you a perpetual, worldwide, non-exclusive licence to use those items to the extent they are embedded in your deliverables.
Open-source components remain subject to their own licences, which we will identify. You own and remain responsible for content, data, trade marks and materials you supply, and you confirm you have the right to give them to us. Unless you ask us in writing not to, we may name you and describe the work in general terms as a client reference.
10. Confidentiality and data protection
Each party will keep the other's non-public information confidential and use it only for the engagement. This continues for three years after the engagement ends, and indefinitely for anything that is a trade secret.
Where we process personal data on your behalf, we do so as a processor on your written instructions, under terms meeting Article 28 UK GDPR. How we handle personal data collected through this website is set out in our Privacy Policy.
11. Warranties and limitation of liability
We will perform the services with reasonable care and skill, using suitably qualified people. We do not warrant that software will be free of every defect, or that it will operate uninterrupted.
Nothing in these terms limits or excludes liability for death or personal injury caused by negligence, for fraud or fraudulent misrepresentation, or for anything else that cannot lawfully be limited.
Subject to that, our total liability arising out of or in connection with an engagement, whether in contract, tort (including negligence), breach of statutory duty or otherwise, is limited to the total amount you have paid us under that engagement in the 12 months before the claim arose.
We are not liable for loss of profit, loss of revenue, loss of anticipated savings, loss of business opportunity, loss of goodwill, or loss or corruption of data, in each case whether direct or indirect, nor for any indirect or consequential loss. You are responsible for maintaining your own backups of live data.
12. Website content
We keep this website accurate but give no warranty that it is free of error or always available. Content on it is general information, not technical or professional advice for your situation. Prices, service descriptions and availability may change without notice.
13. Complaints and disputes
- Tell us first. Email [email protected] setting out the problem. We acknowledge within 5 working days and aim to resolve it within 20 working days.
- If that does not settle it, both parties will consider mediation in good faith through a recognised mediation provider before starting proceedings, with the cost shared equally.
- Failing that, the dispute goes to the courts identified in section 14.
14. Governing law and jurisdiction
These terms and any dispute arising from them are governed by the laws of England and Wales, and the courts of England and Wales have exclusive jurisdiction. If you are a consumer resident elsewhere in the United Kingdom, you may also bring proceedings in the courts of the part of the UK where you live.
15. General
If any provision is found unenforceable, the rest remains in force. A failure to enforce a term is not a waiver of it. You may not assign a contract with us without our written consent. Nobody other than you and us has any right to enforce these terms under the Contracts (Rights of Third Parties) Act 1999. Neither party is liable for failure caused by events beyond its reasonable control. We may update these terms; the version in force is the one published here on the date your proposal is accepted.
