The case of Hoenig v Isaacs might be compared with the decision of the Court of Appeal in Bolton v Mahadeva [1972] 1 WLR 1009 where, by a contract with the defendant, the claimant undertook to install a central heating system in the defendant's house at a cost of £560. The system did not work and the defendant refused to pay any money. The cost of remedying the defects would have been £174. The Court of Appeal held that the claimant was not entitled to recover any of the contract price but, had he offered to remedy the defects, and had then done so, he would be justified in claiming the contract price.
