Browse our curated list of Custom Software Development Companies
To hire a software development company in India from the UK, write a short brief, shortlist three to five registered companies and check their past clients. Start with a small paid discovery phase. Then sign a contract that assigns all code to you in writing, put UK GDPR transfer terms in place before any personal data moves, and pay in pounds or dollars against milestones. You get four to five hours of shared working time every day. US buyers get far less.
This guide covers the parts that are specific to UK buyers. That means the time difference, UK GDPR rules for sending data to India, copyright ownership under UK and Indian law, VAT, the new UK and India trade agreement and a worked cost example in pounds. For the general case for outsourcing, read our guide to outsourcing software development to India. If you also have US offices, our guide for US buyers covers the US side.
Key takeaways
- India is 5 hours 30 minutes ahead of the UK in winter and 4 hours 30 minutes ahead in British Summer Time. A normal Indian working day overlaps four to five hours with London.
- India has no UK adequacy decision. Before personal data goes to an Indian team, you need the International Data Transfer Agreement or the UK Addendum, plus a transfer risk assessment.
- Under UK law, code written by an outside company belongs to that company unless it assigns it to you in a signed document. The contract must also say the assignment is worldwide and permanent, because Indian law fills gaps differently.
- The Indian company doesn't charge UK VAT. If you're VAT registered, you account for it yourself under the reverse charge.
- A UK software engineer contractor costs a median of about £550 a day. The same 1,200-hour build costs about £88,000 at that rate and about £32,000 with an Indian partner at $35 an hour.
Why UK Companies Hire a Software Development Company in India
Cost is the first reason. The median day rate for a software engineer contractor in the UK is around £550, and London roles pay more[1]. Indian partner companies usually quote a fraction of that, and the price often includes a project manager and testing.
The second reason is the working day. The UK sits closer to India in time than almost any other big buyer market. Your team and the Indian team share most of the morning and early afternoon, so questions get answered the same day.
The third reason is the link between the two countries. Many Indian companies already work for UK banks, retailers, councils and startups, so they know UK terms, UK English and how UK clients like to work.
The fourth reason is new. The UK and India trade agreement came into force on 15 July 2026, together with a separate agreement on social security payments[2]. It doesn't change how you buy software services from India day to day. It does make short visits by Indian staff to your UK office simpler, because people sent over for a limited time can stay in the Indian system instead of paying UK National Insurance.
Partner Company, Freelancers or Your Own Team in India?
| Indian partner company | Indian freelancers | Your own team in India | |
|---|---|---|---|
| Contracts | One for the whole team | One per person | Employment contracts through an employer of record or your own Indian company |
| Who runs the work | The company's project lead | You | Your managers |
| If someone leaves | The company replaces them | You find someone new | You hire again |
| Setup time | Two to four weeks | One to two weeks per person | Three to six months |
| Best for | A defined project or product | Small, separate tasks | A long-term team of ten or more |
For most UK companies buying their first project, a partner company is the simplest choice. One contract covers everyone, and the company handles hiring, laptops, payroll and Indian employment law. If you need people working only for you for a year or more, read our comparison of dedicated developers and project-based teams.
A word on IR35. The off-payroll rules are about UK contractors who work through their own limited company. They usually don't come up when you hire an Indian company that employs its own team. If one named person works only for you, full time, for a long period, ask your accountant to check it.
Working Hours: How Much Overlap You Really Get
India Standard Time is UTC+5:30 and India doesn't change its clocks. The UK moves between GMT and British Summer Time, so the gap changes twice a year:
- From late October to late March (GMT), India is 5 hours 30 minutes ahead. 9:00 am in London is 2:30 pm in India.
- From late March to late October (BST), India is 4 hours 30 minutes ahead. 9:00 am in London is 1:30 pm in India.
A typical Indian team works from about 9:30 am to 6:30 pm. In winter that is 4:00 am to 1:00 pm in London, which gives four shared hours from 9:00 am to 1:00 pm. In summer the team's day ends at 2:00 pm London time, which gives five shared hours. Many Indian companies that serve UK clients start later, around 11:00 am, which pushes the shared time into your afternoon.
Use the shared hours for the short daily call, quick questions and demos. Write the rest down. The clock change catches teams out every year, so check the meeting times again in the last week of March and October.
UK GDPR: Sending Personal Data to India
This is the biggest difference from buying in the UK, and the part most buyers skip.
India doesn't have a UK adequacy decision. That means any transfer of personal data from the UK to an Indian company is a "restricted transfer". Before you send it, you need one of the approved transfer tools, usually the International Data Transfer Agreement (IDTA) or the UK Addendum to the EU standard contractual clauses. You also need a transfer risk assessment, which the ICO has a free tool for[3].
Here are the four things to do:
- Keep personal data out if you can. Developers can build and test most software with fake or masked data. Only give production access where the work needs it.
- Sign a data processing agreement. The Indian company is your processor. The agreement says what data it handles, for what, how long it keeps it and how it reports a breach.
- Add the IDTA or the UK Addendum. Attach it to the contract. Most Indian companies that work for UK clients have signed these before.
- Record your transfer risk assessment. For low-risk data such as staff work emails, the ICO tool can be short. For health, financial or children's data, take advice.
On the Indian side, the Digital Personal Data Protection Act 2023 applies to data processed in India. It has an exemption for data about people outside India that an Indian company handles under a contract with a foreign client. So UK GDPR is what really protects your UK customers. That makes your contract terms more important, not less.
Contracts and Code Ownership Under UK and Indian Law
Under UK copyright law, code written by an employee belongs to the employer. Code written by an outside company belongs to that company, even if you paid for it. To own it, you need an assignment in writing, signed by the company[4]. A purchase order or an email saying "you own it" isn't enough.
Indian law adds a trap. Under India's Copyright Act, if an assignment doesn't say how long it lasts, it's treated as lasting five years. If it doesn't say where it applies, it's treated as covering India only. So the clause should say the assignment is worldwide, for the full term of copyright, and covers all code, designs, documents and data the company creates for you.
Your contract should also cover:
- Governing law. Many UK buyers choose English law and the courts of England and Wales. A judgment from the senior UK courts can be enforced in India as if it were an Indian court decision, because India lists the UK as a reciprocating country. Arbitration in London is the other common choice.
- Open source. The company lists every open-source library and its licence, so you don't ship code you can't legally use.
- Handover. You get the source code, passwords, cloud accounts and documents at each milestone, rather than all at the end.
- Staff. The people named in the proposal are the people who do the work, and any change needs your approval.
- Exit. Either side can end the contract with 30 days' notice, and the company must help hand over to a new team.
Our software development contract checklist has the full clause list.
VAT, Tax and Invoices
The Indian company doesn't charge UK VAT. For most business services bought from abroad, the place of supply is where the customer is, so a VAT-registered UK business accounts for the VAT itself under the reverse charge[5]. You add output VAT and claim it back as input VAT on the same return, so for most businesses the cost is nil. If you're not VAT registered, check whether these purchases count towards the registration threshold.
On the Indian side, the company treats your project as an export of services. It normally charges no Indian GST and its invoice will say the supply is for export. There's normally no UK withholding tax on payments for services, so you pay the full invoice.
Ask for invoices that show the company's legal name, address, GST number and bank details, and keep them with your contract. If you ever face an HMRC or audit question, those are the papers you'll need.
Paying an Indian Company From the UK
Most Indian companies accept payment in pounds, US dollars or euros by bank transfer. They receive the money into an Indian bank account and convert it there. Agree the currency in the contract. If you price in pounds, you carry no exchange-rate risk. If you price in dollars, a weak pound makes the project dearer.
Pay against milestones, not in one lump. A common pattern is 10% to 20% up front, then a payment after each agreed delivery that you've tested. Never pay into a personal account, and confirm any change of bank details by phone with someone you've already met.
What It Costs: A Worked Example in Pounds
Take a web application with a customer portal, an admin area and payments that needs about 1,200 hours of work.
| Phase | Hours | Indian partner at $35 an hour | UK contractor at £550 a day |
|---|---|---|---|
| Discovery and design | 160 | $5,600 | £11,700 |
| Build | 800 | $28,000 | £58,700 |
| Testing and fixes | 160 | $5,600 | £11,700 |
| Launch and handover | 80 | $2,800 | £5,900 |
| Total | 1,200 | $42,000 (about £32,000) | about £88,000 |
The UK figure uses the median contractor rate and a 7.5-hour day. The pound figure for the Indian quote uses about $1.30 to the pound. Your quotes will differ, but the gap is usually two to three times. Our software development cost benchmark has rates by role and seniority.
Two things eat into the saving. The first is your own time: someone in your team has to write the brief, answer questions and test the work. Budget a few hours a week. The second is rework when the brief is vague. A clear software project brief is the cheapest way to protect the saving.
How to Check an Indian Company Before You Sign
- Check the registration. Ask for the company's CIN and look it up on India's Ministry of Corporate Affairs site. Check the GST number too. Our guide on how to verify an Indian software company shows each step.
- Call two past clients, ideally in the UK or Europe. Ask what went wrong and how the company handled it.
- Meet the actual team on video. Not just the sales lead. Ask the developers to talk you through a past project.
- Ask about security. ISO 27001 is the most common certificate. If your own UK customers ask you for Cyber Essentials, ask whether the company holds it or can get it[6].
- Run a paid discovery phase. Two to four weeks, fixed price, with a written plan at the end. It tells you more than any sales call.
Our due diligence checklist and questions to ask a software company go into more detail. When proposals come in, use our guide to comparing software development proposals.
Setting Up Communication
- Agree one daily call of 15 minutes inside the shared hours.
- Name one person on each side who makes decisions.
- Use one tool for tasks, such as Jira or Linear, and one for chat, such as Slack or Teams. Keep decisions in the task tool.
- Hold a demo every two weeks where you see working software, not slides.
- Write down the bank holidays for both countries. India has more public holidays than the UK, and Diwali and Holi can take a few days out of a sprint.
Mistakes UK Buyers Make
- Sending live customer data on day one. Put the transfer terms in place first, and use test data where you can.
- Relying on "you own everything" in the proposal. Only a signed assignment works, and it must say worldwide and permanent.
- Picking the lowest quote. A quote far below the others usually means missed scope or junior staff.
- Forgetting the clock change. A meeting at 9:00 am London time moves by an hour in India twice a year.
- Treating the team as a ticket queue. Teams that understand why a feature matters build better software. Share the goal, not just the task.
Red Flags
- The company won't put the code assignment in the contract.
- It won't sign a data processing agreement or the IDTA.
- It won't let you meet the developers before you sign.
- It asks for most of the money up front.
- It can't name a single client you can call.
- It keeps the code in its own accounts and won't give you access.
Your First 30 Days
- Week 1: Sign the contract, the data processing agreement and the IDTA. Set up shared tools and give access to your code and cloud accounts.
- Week 2: Run discovery workshops in the shared hours. The company writes up the scope, a plan and risks.
- Week 3: Agree the first milestone and how you'll test it. Start the first sprint.
- Week 4: See the first demo. Check that the code is in your repository and that the team is the one you were promised.
What UpBusiness Partner Data Shows
We looked at the 46 partner companies on our software development page on 31 October 2026, most of them based in India.
- Their TrustScores run from 70.17 to 75.85 out of 100, with a median of 71.67.
- Of the 45 that report an average project size, 22 average $5,000 or less. The median is $10,000.
- 38 of the 46 have 50 employees or fewer.
On our custom software development page, 12 companies are listed and 6 of them list custom software as a core service. Smaller companies suit a first project well, because your work gets senior attention.
How Hiring Works on UpBusiness
Every partner company on UpBusiness has passed five checks reviewed by our team: company details, registration and tax papers, the founder's identity, expertise and three client projects with evidence. Only companies with a TrustScore of 70 or more are listed.
- Post your requirement with the service, a rough budget and that you're based in the UK.
- Get three partner companies matched to your budget, service and industry.
- Compare them side by side, meet them on video and contract with the one you choose. Buyers pay nothing, and there's no commission on the project.
Then follow the steps in this guide: transfer terms, a written code assignment, milestones and a paid discovery phase. That's how UK companies get the saving without the surprises.
