Oh it's totally ugly, no doubt about that. As for breaking, it's worth paying extra for quality trunking & fittings. The make of electrical fitting is usually specified by the local authority, but the trunking isn't & the contractors or subbies can claw in a bit extra using cheappie trunking.
On a big contract, that can add up to a nice little bit.
You must be lucky with your council, most won't let you refuse safety upgrades. When I was doing council contracting, you had to report any refusals back to the council. They could then take what they deemed appropriate action, if the Tennant still refused to cooperate they could seek eviction & posession orders.
