How Much Does a Power BI Consultant Cost in the UK?

How much does a Power BI consultant cost? It's one of the first questions on almost every first call we have at Metis BI, and fair enough, budgets need numbers. The problem is that the number a lot of people find online is a contractor's day rate, and then every quote that lands afterwards gets measured against it.

I've sat on every side of this. I built and ran a Power BI practice inside a large UK consultancy for years, I've interviewed hundreds of contractors along the way, and now I run a specialist consultancy. So here's what each option costs, what those numbers actually measure, and where the money really goes.

The quick answer: In the UK, Power BI contractors typically charge around £400 to £675 a day depending on seniority and location, specialist consultancies roughly £700 to £1,100, and big consultancies from about £1,200 to £1,900 or more. Those are three different products, so comparing them day for day tells you very little. The number worth comparing is the total cost of getting the outcome you need, including your own team's time and any rework along the way.

Key takeaways before we get into it:

• Many of the rates you'll find quoted online are contractor rates, a skilled pair of hands working inside your plan.
• A specialist consultancy charges more per day and usually needs fewer days, because the method, standards and senior thinking arrive with it.
• What moves a price most is the state of your data, your semantic model and how clear your requirements are.
• A fixed price is only as honest as the scope underneath it. Fixed price on undefined work tends to end in change requests.
• Whoever you hire, you should finish with documents and capability you own.

The UK Power BI day rate you keep seeing is a contractor rate

A source you'll see quoted a lot for UK rates is ITJobsWatch, and it's a good one. It tracks contract job adverts that mention Power BI. At the point of writing this blog, in the six months to 24 October 2026, it logged 1,217 quoted daily rates. The middle half of those sat between £405 and £600 a day, and the top 10% started at £675. London came in at a median of £513, the rest of the UK at £463. From interviewing and working with contractors over the years, that spread mostly comes down to seniority, with location, sector and things like security clearance doing the rest.

Here's the thing though. Those adverts are for people joining someone else's team. Often a recruiter places them, the client directs them, and the client decides what good looks like. That's a perfectly good number for what it measures. It just measures something different to what most people mean when they ask what a consultant costs.

I like to explain it with building work. A contractor is a skilled tradesperson you bring onto your site. They build exactly what's on your drawings, quickly and well, and that's the deal, whether the drawings are right or not. A specialist consultancy is closer to a small design and build firm. The person who drew the plans is the same person on site every day, so when something looks off halfway up the wall, it gets spotted and fixed before the plaster goes on. A big consultancy is the main contractor on a large job, with a site office, project managers and layers of subcontractors underneath. Brilliant if you're building a hospital. For a kitchen extension, a lot of what you're paying for is the site office.

All three have their place. But if you hand a brilliant bricklayer the wrong drawings, you get a beautifully built wrong wall.

Three shapes of Power BI help, and what each one costs

I've written a full comparison of freelancers, specialist consultancies and big consultancies, including where each one breaks, so here's the one minute version with the money added.

‍

‍

The contractor range comes from the ITJobsWatch figures above. The consultancy bands come from my own years inside a large consultancy and from the day rate bands UK consultancies publish on their own sites. They vary between firms, so treat them as a guide.

Seniority is worth a quick word, because it works differently in each shape. A senior contractor sits at the top of their range, which puts them much closer in price to a specialist consultancy than the headline numbers suggest, without the method, standards and accountability that come with a consultancy. A big consultancy usually charges by grade from a rate card, and the grade on the invoice isn't always the grade doing the work. At a specialist consultancy like ours, it's senior people throughout, so the rate you pay is for the people you met.

‍

‍

You'll also come across offshore teams quoting much lower rates than any of these. The rate is real. So is the extra management on your side, the time zone gap and, in our experience, the rework when the model underneath wasn't built to any standard. If you go that way, make sure someone very senior oversees it, either from your own team or brought in. We've done exactly that at Metis BI, joining a report migration to oversee an offshore team that a large consultancy had assembled, after the client came across some challenges.

Why a contractor isn't just a cheaper Power BI consultancy

I get versions of this a lot... "why would I pay a consultancy almost double when a contractor can build the same report?" Fair question.

A good contractor is fast, focused and genuinely cost-effective when the plan already exists. What they don't usually bring is the plan itself, because that isn't what they're hired for. Somebody still has to gather the requirements, check the data, set the modelling standards, review the work, push back when a requirement is wrong and hold onto the knowledge when the contract ends. If that somebody is on your payroll, their time is part of the price. It just never shows up on the invoice.

I'll be honest about the other side of it too. I've seen this more times than I can count over the years... a contractor comes in, does exactly what the ticket says and nothing more, then moves on to the next contract. To be fair, I've worked with some brilliant contractors as well, and most times it comes down to the model more than the person. A contractor is paid for the days on the contract. When it ends, the next one starts somewhere else, and nothing in that arrangement rewards the extra hour spent documenting a model or pushing back on a requirement.

With a boutique consultancy like Metis BI, that work comes with the engagement, and so does a reputation. Our name is on every piece of work we deliver, and our client reviews are independently verified on Clutch, so what we build has to hold up long after we've left. Every engagement is led by me from the first call to handover, and we run the same proven method every time, refined over more than ten years of Power BI delivery. Requirements and a data check come first, then wireframes, then the build.

When a project needs extra depth, data engineering, say, or a second senior developer, I bring in specialists I've worked alongside for five years or more, most of them from the Power BI and analytics practice I built and ran at Adatis, now Telefónica Tech. We never use recruitment firms and we don't staff work with strangers. Everyone works to our standards and our method.

That's what the higher day rate pays for. The thinking, the standards and the continuity that would otherwise land on your team.

What drives the cost of a Power BI project

Two quotes for what sounds like the same project can be miles apart. In my experience the gap usually comes down to different assumptions about what's in scope. These are the things that move the number most:

• Whether a sound semantic model already exists: if it doesn't, the first report quietly becomes a model build, and that's usually where most of the effort goes. I've written about why the semantic model is the centre of everything if you want the longer version.
• The state of your data sources: clean, well-structured sources are quick to work with. Spreadsheets, manual extracts and systems that disagree with each other are not.
• How clear the requirements are: if nobody can yet say which decisions the report needs to support, that work has to happen before anything gets built.
• Security and governance needs: row-level security, sensitive data and who sees what all add design time, and they're far cheaper to plan in than to bolt on later.
• Deadline pressure: a date that can't move usually means more people working in parallel, which costs more.
• Regulated environments: more evidence, more sign-off and more documentation, all of which take time.

A good consultant will ask about most of these before giving you a number. If someone prices your project in the first ten minutes without asking about your model or your data, they're guessing.

Where the real savings come from

So if a specialist consultancy costs more per day, where does the saving come from? From four places, in our experience:

• Fewer days: we reuse patterns refined across a lot of engagements, and we now use AI to speed up report wireframing, building on years of doing it by hand, at the same quality. Signed-off wireframes then guide the build. Less of the work gets figured out on your time.
• Less of your team's time: far less internal time goes on writing specs, managing a developer day to day and reviewing every measure.
• Right first time: requirements and data are checked before the build starts, so you're not paying for the same report twice.
• Knowledge that stays: documented models, agreed definitions and a team that's been involved throughout, so the knowledge is still there when the engagement ends.

A worked example, with made-up numbers

To show the shape of it, here's an illustrative comparison for the same reporting project. The numbers are invented to make a point, they're not a quote from anyone.

‍

‍

The £280 a day internal cost is roughly what the median Power BI salary costs an employer per working day once National Insurance is added, £55,000 plus £7,500, spread over about 225 working days after holidays and bank holidays (more on salaries below). That's before pension and other overheads, so the real figure is higher.

Notice the gap in pounds isn't enormous. The bigger difference is what you're left holding at the end. On one route you have a working report and a model only one person understood. On the other you have a documented model, agreed definitions and a team that knows how both work.

The day rate is the price of the input. What you actually end up paying for is the outcome.

Why the cheapest Power BI dashboard often costs the most

I've inherited a fair share of builds over the years, and I still do with Metis BI. The first wave of questions is usually fine, the report answers what it was built to answer. Then the business asks the second wave. Can we see it by region? Can we compare it to budget? Why doesn't this match what finance says?

That's when you find out whether there's a proper model underneath. If there isn't, every new question needs part of it rebuilt, and the organisation ends up paying twice, once for the quick build and again for the foundations it skipped.

These are some of the hardest conversations I have, because the client did nothing wrong. They bought the cheapest quote that looked like the same thing.

When a fixed price is honest, and when it isn't

Over the last two years, more than one organisation has come to us after being promised a fixed price for a solution nobody had properly defined. Then came the change requests. One after another, back to back, because every stage, requirements, design, development, uncovered more of what the project actually needed. The fixed price turned out to be the starting price.

I always tell my clients this early on. If you're promised a fixed price for something that isn't clearly defined, and you yourselves aren't sure what it needs or how it will work... run! Or at the very least, read the contract and the small print very carefully, especially the part about how change is handled.

You'll also hear the opposite argument, that if a firm won't fix a price for reviewing your Power BI estate, they probably haven't done many. Sometimes that's fair. Often it isn't. There are good reasons an experienced firm will decline to fix a price on a review:

• The estate is vast or complex: hundreds of reports, several tenants, or a Microsoft Fabric platform underneath it all.
• You can't yet say what the review should answer: in that case the requirements need gathering first, and pricing before that is guesswork.
• Nobody can see the estate before signing: access, security and NDAs often mean the first proper look happens after the contract.
• The depth varies hugely: a review of the reporting layer is a very different job to one that covers the data platform, security and capacity too.
• It's a regulated environment: extra evidence and assurance take extra time, and that's hard to predict from the outside.

Fixing a price anyway in those situations usually means one of two things. Padding the number to cover the unknowns, or coming back later with change requests. Neither is good for you.

So here's how we do it. Where the scope can genuinely be defined, we fix the price. Our Power BI Health Check is a fixed £795 for a defined scope, one business area, up to five reports and two semantic models. Our governance and performance optimisation work is fixed price too. For anything bigger, we gather the requirements and check the data first, then give you a price for the work that's actually in front of us.

Requirements gathering should leave you with something you own

Some firms call this stage discovery. Whatever the name, it's often necessary, and it shouldn't end with a slide deck and a vague promise of a phase two. By the end of it, you should own:

• the requirements, written down and agreed with the people who will use the reports
• an assessment of your data and its quality, including what exists and what doesn't
• wireframes of the reports, signed off before anything is built
• a scope and estimate for the build

All of that should be clear enough that you could take it to any supplier, including someone other than the firm that produced it. If the early work only makes sense as long as you keep paying the same supplier, that tells you something.

How to tell if a Power BI consulting quote is reasonable

Before you compare any two quotes, ask each of them these questions:

• Did they ask about your model and data before pricing? If not, the number rests on assumptions you haven't seen.
• Is there a detailed breakdown by phase? Ask for the activities planned in each phase, from requirements through to handover, so you can see what you're paying for and spot what's missing.
• Is it clear how changes will be handled? You want this in writing, before you need it.
• Are the people doing the work named? And did you meet them, or only the person selling it?
• What does the early stage hand over? Documents you own, or a slide deck?
• What do you own at the end? The model, the reports, the documentation and the knowledge should all be yours.
• Does the price include Microsoft licences? Usually it won't. Depending on how many people need access and whether you're on Fabric capacity, licensing can be a meaningful line of its own, and Microsoft's guide to Power BI features by licence type is a good starting point.

If you want the full vetting process, I've written a separate guide on how to choose a good Power BI consultancy.

Hiring instead? What a Power BI salary really costs

The other comparison most organisations run at some point is hiring someone permanently. According to ITJobsWatch, the UK median advertised salary for permanent roles citing Power BI was £55,000 in the six months to 25 October 2026, with the middle half between £41,250 and £72,500. London sat at £65,000 and the rest of the UK at £50,000.

On top of salary, employers pay National Insurance at 15% on earnings above £5,000 a year, per HMRC's rates for 2026 to 2027. On a £55,000 salary that's another £7,500, before pension, equipment, licences, recruitment fees and cover for holidays and sickness.

So the honest guide looks something like this:

• Hire: when there's enough steady Power BI work to keep someone busy all year, and someone senior enough internally to direct them.
• Contractor: when the plan, spec and standards already exist and you need extra hands for a defined stretch.
• Specialist consultancy: when you need the problem owned, the foundations set up properly, or your own team upskilled along the way.

The strongest setups I see combine them, external expertise building alongside growing internal capability. I go into that more in whether you need a consultant or in-house is enough.

Why we don't publish a day rate

We don't publish a day rate, and I'll be straight about why. A day rate on its own invites exactly the comparison this whole blog argues against, our day against a contractor's day, when the work behind each one is completely different.

What we do publish is fixed prices wherever the scope allows it. For everything else we gather the requirements first and give you a total before you commit to anything. If you need a number to take to your finance team, ask on the first call and you'll get a straight answer.

When a contractor is the right, and cheaper, answer

Let me be clear, sometimes the right answer is a good contractor, and I'll tell you that on a call.

If your plan, spec and modelling standards already exist, and you have someone internally who knows what good looks like and can direct the work, a contractor is often the most cost-effective option. In that situation a consultancy would be the expensive choice, and I'd rather you hire well than hire us.

If you're not sure which shape of help you need, a small fixed-price review is a low-risk way to find out. Our Power BI Health Check looks at one business area of your estate, the reports, the semantic models underneath and how they're governed, and gives you a clear view of what's working, what isn't and what to fix first. The fee comes off any follow-on work if you go ahead with us. It suits organisations that know something isn't right but aren't ready to commit to a bigger engagement. Learn more about the Power BI Health Check.

Summary

A Power BI consultant in the UK can cost anything from around £400 a day for a contractor to £1,900 or more for a big consultancy, with specialist consultancies sitting in between. Those numbers describe three different things. A contractor brings skilled capacity into your plan, and you supply everything around it. A consultancy owns the problem and brings the method, standards and continuity with it.

So compare the total cost of the outcome. Count your own team's time, count the rework, and be wary of any fixed price on work nobody can yet define. Whoever you choose, make sure you finish with documents, models and knowledge you own, and a team that's stronger than when you started.
