If you have trace and access cover on your building insurance policy, then effectively it will cost you nothing!
Often there will be an excess of a few hundred pounds on most policies, but this is all it should cost to locate, access and restore the affected area.
However, any repairs to pipework are maintenance of your property, and you must pay for these to be carried out. However, with the cost of finding and getting to the leak covered, this is often a fitting costing about £1 and the labour to fit.
Due to repairs not being covered under insurance, we do not offer a repair service as it becomes a conflict of interest with the insurance claim. Better to have an independent plumber repair, a bit annoying but better than risking problems on the whole claim.
