Seaham sits on the Durham Heritage Coast, a short drive south of Sunderland along the coast road. It was built as a port for the coal industry, and after the collieries closed the town has changed a great deal. The harbour now has a marina, the clifftop and beaches have been cleaned up and are popular with walkers and sea glass hunters, and new homes have been built around the town. Our team in Sunderland is close by, and we help Seaham households and businesses find the right connection.
Home workers and families
Many people in Seaham commute to Sunderland, Durham or along the A19, and a large number now work from home for at least part of the week. That has changed what households need from their broadband. A connection that was fine for streaming in the evening may struggle when someone is on a video call during the day, another person is uploading work files and the children come home and start gaming.
When you choose a package, look at the upload speed as well as the download speed. Upload is what carries your side of a video call and sends files to colleagues. Our home full fibre packages show the speeds and clear prices including VAT for your address, and yearly rises are fixed in pounds and pence in your contract.
Homes in Seaham include older colliery terraces in areas such as Dawdon and New Seaham, family houses in Deneside and Parkside, and newer estates on the edges of town. Older terraces can have thick walls that block WiFi, and newer houses with an open plan downstairs and several bedrooms upstairs can still have weak spots. Mesh units spread the signal through the whole house. See our WiFi page.
Switching from your current provider uses One Touch Switch, so your old and new providers arrange it between them. Our switching page explains how it works, and you have 14 days to change your mind after signing up.
Local shops, cafes and small firms
Church Street, Byron Place and the streets around the harbour are home to independent shops, cafes, takeaways, salons and small offices, and the seafront draws visitors on sunny weekends. For businesses like these, the connection has to be dependable for card payments, online orders and bookings, with clear prices and someone local to call if something goes wrong.
Business full fibre gives you business terms, a router set up before your go live date if you want one, and support from our Sunderland team. If you run a small business from home, a home package may be all you need, and we will tell you honestly which suits you.
There are also industrial estates and business units on the edges of Seaham, with manufacturing, engineering and service businesses. Larger sites with heavy data use, or a need for guaranteed speeds, may be better suited to a leased line, which we quote for after a site survey.
Old phone lines are being switched off
The national switch off of the analogue landline network is due to finish by the end of January 2027. If you still rely on a traditional phone line at home or at work, now is a good time to plan the move. You can add a digital phone line to your Cyber Fibre broadband and keep your number, and our sister brand Virtual Voice Office provides phone systems for teams.
