We cannot provide a definitive answer to this question and the reason is simple: the price of a fence varies according to the materials you choose, the contractor you hire for installation and how much fence you need.
When it comes to materials, you have different choices: wood, metal (aluminum, forged iron, steel, chain link), vinyl or brick. Each material has different properties and functions. Brick fences ensure privacy and are soundproof, steel fences are used for protecting enclosures, while forged iron fences are used rather as decorative elements.
The prices vary greatly. Chain link fences are cheaper but they are used mostly in agriculture and industry, metal fences are expensive, while wooden fences cost a lot in terms of labor. Currently, the material providing the best quality-price ratio is vinyl.
Hiring a Brighton fence company specialist to install your fence will have a cost, but you can be sure that it will be built to last. You can save it by doing a DIY project, but this is not recommended unless you have some experience in what you are doing otherwise you risk losing even more money.
You must also calculate how much fencing you need. Its length influences the installation and the amount of materials. Obviously, a longer fence will be more expensive.
