A poor TV aerial signal is one of those problems that's easy to live with for months longer than you should, simply because it's not always obvious whether the fault is the aerial, the cable, or the TV itself. Most of the time, it's the aerial or the cabling running to it — weather, age and shifted brackets do more damage over the years than people realise. Every job is carried out by a DBS-checked engineer, and every installation and repair comes with a 12-month guarantee, so if something isn't right after we've gone, we'll come back and put it right.

Common Problems
Signs You Might Need This Service
Pixelated or blocky picture
Signal breaking into blocks or freezing, especially in wind or rain, usually points to a weak or unstable connection.
No signal / weak signal message
An intermittent or permanent error message that started suddenly usually means something has physically changed — the aerial has moved, a cable has failed, or the aerial has been damaged.
Reception drops after storms
Years of UK weather take their toll on brackets, mounts and cabling — reliably worse reception after high winds is a sign the fixings need checking.
Pricing
What Does It Cost?
Aerial costs vary depending on the type of aerial, how accessible your roof or chimney is, how much cabling is needed, and whether it's a repair or a full new install. We don't quote blind over the phone for anything beyond a simple job — call or WhatsApp us with a few details and we'll give you a straightforward, no-obligation price before any work starts.
Every aerial installation and repair is backed by our 12-month guarantee, and our engineers are DBS-checked and fully insured, so you can have someone in your loft or on your roof with confidence.
FAQs
Common Questions
Do I need a new aerial or can mine be repaired?
In many cases a fault is a loose connection, damaged cable or a shifted bracket, all of which can be repaired. We'll always repair rather than replace if it's the more cost-effective option for you.
How long does an aerial installation take?
Most single-TV aerial installations are completed within a couple of hours, including a full retune and signal check.
Can you install an aerial in a loft instead of on the roof?
Yes, where signal strength allows it a loft aerial can be a good option, avoiding any roof or chimney work at all.
Do you work on flats and new-build homes as well as houses?
Yes, we install and repair aerials for houses, flats, and new-build developments, including communal systems where access allows.
All work is covered by our 12-month guarantee, and our engineers are DBS-checked and fully insured for your peace of mind.
