5. Danny & Danielle and Sarah & Aled

On the Cornish coast, Danny and Danielle take on a multimillion-pound mansion with spectacular views - and spectacular problems. A storm batters the sea wall, emergency repairs mount up and before work can even begin, they must find £40,000 to rehome the resident bats. In north Wales, the clock is ticking for Aled and Sarah. They want to move in together before their wedding in just a few months, but with the renovation funded by their monthly income, they're doing the hard graft themselves.
