Quick summary

Choosing a creative agency for TV ads typically costs between £100,000 and £200,000, which includes script, casting, filming, and editing, with extra expenses for special effects or music. Costs vary based on complexity, location, and talent, so plan your budget accordingly, especially if you want a quick launch within a tight timeframe.

My growth and marketing experience up until now has been heavily digital. Like most digital marketers, I’m comfortable using channels where I can easily measure the return on investment –  which is not the case for television. But despite the rise of digital, TV still has significant reach. Many people still watch TV on a regular basis and it fosters an “as seen on TV” trust factor which is essential in our industry.

Resi has been operating for seven years, bringing an innovative technological approach to traditional architecture. We decided it was the right time for us to hit TV because we wanted to accelerate our brand awareness to help us move from successful start-up to confirmed scale-up. Given that in our line of work we’re dealing with large budgets that directly affect people’s homes, word of mouth, personal recommendations and trust are key elements in decision making. TV enables us to speak to as many people as possible and enforces an element of trust and brand credibility.

All that said, when we started our TV journey, it was a bit like renovating a house. We didn’t really know where to begin, who to contact – especially not how much it would cost. Now the ad is finally live on prime time ITV, I’ve put together a series of articles to share everything we didn’t know about making a TV ad to help other startups or scale-ups considering this marketing channel find their feet. In this article, I’ll discuss how we went about choosing a creative agency, how much shooting a TV ad can cost, what that includes and how to reduce the budget where possible.

1. Determine your objectives

Before you start talking to agencies, it’s essential to outline what you actually hope to achieve by investing in TV advertising. Making a TV ad is very expensive and time-consuming so jumping in without knowing what you’re aiming for is potentially really wasteful. So, first things first, I made a list of our top priorities to help keep us on track later on:

  • Increase public knowledge and recognition of Resi – as a little-known brand, I knew it could be a real challenge.
  • Communicate Resi’s revolutionary role in a traditional sector – people have a fairly good understanding of architecture practices but what we do is a little bit different so explaining this properly was really important.
  • Get across to a wider audience why Resi is a credible and trustworthy choice.

2. Choose your partners

There are many more players in the process of running a TV ad than I could have anticipated. We’re talking communications agencies that introduce you to media buying agencies, who then introduce you to creative agencies that work alongside production agencies. The list goes on!

As a quick overview you will probably need:

  • A communications agency: Unless you are rock-solid on your audience and messaging, a communications agency can be a really good investment. Considering how big your investment in TV will be, spending a little bit more to ensure that you’re saying the right things to the right people makes sense.
  • A creative agency: This is the agency that will take your messaging and transform it into a creative concept with a script and storyboard.
  • A production agency: These are usually managed by the creative agency in order to transform their vision into your final creative.
  • A media buying agency: This is the agency that will get your ad “out there” by buying the airtime. I’m not going to talk in too much detail about media buying in this series and the reason is that we ran our ad campaigns as part of ITV’s Media for Equity portfolio and so our media buying was relatively straightforward. I might circle back on this at a later date with insights into what we learned about broadcast times, different regions, etc but as the first campaign is still currently running, it’s too soon to judge what our key learnings are.
