If I am honest, I am a huge fan of pensions.
Alongside ISAs, they are one of the most tax efficient ways to build long term wealth in the UK, and yet they are also one of the most ignored. I understand why. Try telling 18 year old Dave to start saving into a pension and he would have told you exactly where to go. Retirement feels miles away, life is happening now, and locking money away until your late fifties is hardly appealing.
But as you get older, your perspective shifts (mine certainly has). You start thinking less about the next year and more about the next twenty or thirty. You begin to realise that building wealth is not about quick wins, it is about consistency, structure, and putting the odds in your favour. That is when pensions start to make a lot more sense.
Do You Need a Pension in the UK?
Technically, no, you do not need a pension in the UK. You could invest through ISAs, property, or general investments and still build significant wealth over time. Plenty of people do exactly that.
But the real question is not whether you can avoid a pension, it is whether it makes sense to. Because if you choose not to use a pension, you are effectively ignoring one of the most powerful tax wrappers available to you in the UK. In a world where building wealth is already hard enough, turning down tax advantages feels like making life more difficult than it needs to be.
How Much Is the UK State Pension and Is It Enough?
A lot of people assume the State Pension will cover them in retirement, so they do not need to worry too much about building their own retirement pot.
At the moment, the full new State Pension is just over £11,500 per year and you can access it at 66 (and rising soon). That gives you a base level of income, but it is not going to fund the lifestyle most people want after decades of working. It covers the basics, not much more.
There is also a bigger question around sustainability in my view. The triple lock is expensive, the population is ageing, and fewer workers are supporting more retirees. It is difficult to see how the system remains exactly as it is today over the long term. Does the age keep increasing? Does it become less generous? Does it evolve into something different entirely?
No one really knows.
That is why I would be cautious about relying on the State Pension alone. It should be seen as a foundation, not the full plan.
How Pensions Have Changed in the UK: DB vs DC
One of the biggest shifts in pensions in the UK has been the move from defined benefit schemes to defined contribution schemes, and this has completely changed the responsibility placed on individuals.
Defined benefit pensions, often called final salary schemes, used to provide a guaranteed income in retirement based on your salary and years of service. The employer carried the risk, and from an individual perspective, it was relatively straightforward. My father was a teacher and has a good, steady pension that is paid out to him each year and he does not manage it.
Today, most people are in defined contribution pensions. Instead of being promised an income, you build a pot of money that is invested in the markets and with your discretion. What you end up with depends on how much you contribute and how those investments perform over time.
In simple terms, we are now in charge of sorting our own pensions.
That is good in one way because it gives you control and flexibility. You are not tied to one employer, and if you invest well, you can build meaningful wealth.
But it is also a challenge. Most people are not particularly interested in investing, and many are not educated on how pensions work. That can lead to inaction, poor decisions, or simply not engaging at all.
The good news is that this is starting to change. More people are taking an interest, platforms are improving, and conversations around investing are becoming far more normal.
What Is a SIPP and Should You Use One?
A SIPP, or Self Invested Personal Pension, is one of the most powerful tools available if you want more control over your pension in the UK.
Instead of relying purely on a default workplace pension fund, a SIPP allows you to choose your own investments. That might include index funds, ETFs, or other assets depending on your approach. The range of investments you can invest in just keeps growing.
For me, this is where pensions become really interesting from a wealth building perspective. You still benefit from tax relief and long term compounding, but you can align your investments with your own strategy, whether that is low cost global trackers or something more tailored.
Many people use a combination approach. They contribute to their workplace pension to get the full employer match, and then use a SIPP for additional contributions and greater control (For the 2026/27 tax year, the standard maximum pension contribution with full tax relief is £60,000 or 100% of your annual earnings (whichever is lower) ).
It is not about replacing one with the other, it is about using both in a smart way.
A Quick Note on My SIPP Project
I have recently started a small project where I invest £1 into a SIPP for every new Instagram follower. It is a bit of fun, but also a good way to demonstrate how investing regularly, even in small amounts, can build over time.
I am using InvestEngine for this and have been really impressed so far. It is low cost, simple to use, and feels like a great option for beginners who just want to get started without too much friction. It is ETF only but that suits me as I rarely invest in single stocks.
If you are considering opening an account, I do have a referral link below where we both receive a small bonus if you sign up:
As always, this is not advice, just sharing what I am doing.
Why Pensions Are So Powerful in the UK
The biggest advantage of pensions in the UK is not just that you are saving, it is how you are saving.
Tax relief gives you an immediate uplift on your contributions. Employer contributions add another layer of value. Then you have decades of potential investment growth through compounding. Investing in my SIPP has been a good way to legally reduce my tax bill as well.
When you combine all of these, pensions become incredibly efficient for long term investing.
Yes, the money is locked away, and that is often seen as a downside. But in many ways, that restriction creates discipline. It forces you to think long term and prevents short term decisions from derailing your plan.
Pension vs ISA: Do You Need Both?
A common question is whether a pension is better than an ISA in the UK.
In reality, they serve different purposes, and for most people, the answer is to use both. It is what I do.
Your pension is your long term, tax efficient pot designed for later life. Your ISA is your flexible pot that you can access at any time.
Used together, they give you structure and flexibility, which is exactly what you want when building wealth.
So, Do You Need a Pension in the UK?
You do not need a pension in the UK.
But if you are serious about building long term wealth and giving yourself options later in life, it is very difficult to justify ignoring it.
For me, pensions are a core part of the plan. Not the only part, but a key one. The combination of tax relief, employer contributions, and long term compounding is simply too powerful to overlook.
And while younger you might not care about retirement, older you almost certainly will.
Final Thoughts
If you are just getting started, keep it simple. Make sure you are enrolled in your workplace pension, contribute enough to get the full employer match, and then build from there. If you want more control, consider adding a SIPP alongside it.
You do not need to overcomplicate things.
You just need to start. The way I think about it is to not think about it too much. I have a small workplace pension which just ticks over and I add to my SIPP whenever I can.
Because when it comes to pensions, time is doing more of the heavy lifting than anything else.
