We are asked about in Tredegar most weeks, usually after something has changed at the property. Everything else — brand of gear, exact scope, upgrade suggestions — is downstream of that. Property in Tredegar varies street to street, so the honest answer to "what will it cost" is that it depends on invoice routes to the landlord as standard. Split billing — checkable in under an hour. Around NP22 it is the single most common reason a job runs long.
The most useful thing you can tell us on the first call is what changed immediately before you noticed the problem. For valley terraces around Sirhowy and Georgetown that detail matters more than it does elsewhere. If a previous certificate exists, consumer unit upgrades for hmo landlords usually starts by checking whether it still reflects reality.
