We send vetted CVs that match your stack and experience level.
Interview
You interview and test candidates yourself, so you only hire people you're confident in.

Sign the NDA and contract, set up access, tools and communication channels.

Your developer starts, with regular check-ins and a no-fuss replacement if the fit isn't right.
Choose the right hiring model
Pick the model that matches how much control you want and how long you need the help.
| Model | Best for | Who manages the work | Billing |
|---|---|---|---|
| Dedicated developer | Ongoing development or a long-term product | You, with our support | Monthly |
| Team augmentation | Filling skills gaps or hitting a deadline in your existing team | You | Monthly or hourly |
| Dedicated team | Building a product without growing your own headcount | Our project manager, reporting to you | Monthly |
| Hourly support | Maintenance, small changes and uncertain scope | Shared | Hourly |
| Fixed-price project | A clearly defined build with a fixed scope | Us, against agreed milestones | By milestone |

Cost to hire custom software developers in the UK
Indicative rates for a mid-level to senior developer. Your exact quote depends on skills, seniority and contract length.
| Option | Hourly rate | Monthly cost (full time) | Best for |
|---|---|---|---|
| UK-based developer | £60 to £120 | £7,000 to £12,000+ | On-site work, highly regulated projects, close daily collaboration |
| Hybrid team (UK management, offshore developers) | £25 to £50 | £3,000 to £6,000 | Long-term development at a lower cost, with UK-hours coordination |
Rates are indicative and exclude VAT.
What hiring in-house really costs
Comparing a day rate with a salary can be misleading. When you employ a developer directly in the UK, the salary is only part of the cost:
| Cost | Employing in-house | Hiring through Fulminous |
|---|---|---|
| Employer National Insurance | 15% on earnings above the threshold | Included |
| Workplace pension | At least 3% employer contribution | Included |
| Recruitment | Agency fees or weeks of internal hiring time | No fee |
| Equipment, software and training | Paid by you | Included |
| Holiday and sickness cover | Work pauses | Cover arranged |
| Scaling down | Notice periods and redundancy rules | Monthly notice |
What affects the price
- Seniority and specialist skills, such as AI, security or Salesforce
- Technology stack and how niche it is
- Contract length, with longer commitments usually costing less per month
- Team size and whether you need a project manager or QA
- Compliance needs, such as security clearance or regulated sectors

UK, offshore or hybrid developers?
Each option has genuine strengths. Many UK businesses choose a hybrid model to balance cost and communication.
| Factor | UK-based | Fully offshore | Hybrid (our model) |
|---|---|---|---|
| Cost | Highest | Lowest | Lower than UK-only |
| Time-zone overlap | Full | Limited | UK-hours management and overlap |
| On-site meetings | Easy | Rare | Available with the UK team |
| UK market and regulation knowledge | Strong | Varies | UK-led planning and review |
| Scaling speed | Slower | Fast | Fast |

FAQs about hiring custom software developers in the UK
Is it better to hire custom software developers in the UK or offshore?
Both have advantages. UK-based developers offer full time-zone overlap, easy on-site meetings and strong local market knowledge. Offshore developers cost less. A hybrid model, with UK-based management and offshore developers, gives many UK businesses a good balance of cost, communication and quality.
How quickly can I hire custom software developers?
Most clients have a developer working on their project within 7 to 14 days. Timing depends on the skills and seniority you need, how quickly you can interview, and how many developers you're hiring.
How much does it cost to hire a software developer in the UK?
As a guide, UK-based developers typically cost £60 to £120 an hour, or £7,000 to £12,000 or more a month full time. Hybrid teams with UK management and offshore developers typically cost £25 to £50 an hour, or £3,000 to £6,000 a month. Rates depend on skills, seniority and contract length.
Can I interview developers before hiring them?
Yes. We send matched profiles and you interview and test candidates yourself. You only hire developers you're confident in, and we'll arrange a replacement if the fit isn't right later.
Do you sign an NDA and transfer IP ownership?
Yes. We sign a Non-Disclosure Agreement before you share project details, and full ownership of all source code, designs and documentation is transferred to you.
How do you keep our code and data secure?
Developers work in your repositories and accounts with least-privilege access, follow secure coding practices, and use peer review, automated testing and security scanning. Projects are built with UK GDPR requirements in mind, and access is removed when the engagement ends.
Can I scale my development team up or down?
Yes. You can add developers as your project grows or reduce the team with monthly notice, without long-term commitments.
Does IR35 apply when I hire developers through Fulminous?
IR35 mainly affects businesses hiring individual contractors through their own limited companies. Engaging a company to provide developers under a service contract can simplify this, but every situation is different, so confirm your position with your accountant or legal adviser.
