A £1,000 construction website is worth it if it wins you two jobs you would not otherwise have had. For most builders and trades, that is a handful of enquiries over the life of the website.
Illustration, not a client result: if each new job leaves you £500 profit, a £1,000 website pays for itself after two jobs.
Compare that with a subscription website builder at about £22 a month, which costs more than £1,000 after four years and still does not belong to you. The full breakdown of DIY, freelance and agency prices is in the guide how much does a construction website cost in the UK.
