On 26th April, we launched a social media campaign called #ventyourrent on Twitter and Tumblr. We asked people to tell us on cardboard, a photo, or just a tweet, what they were paying in rent and what it bought them.

The plan was to get Londoners sharing their worst experiences of renting and generating some solidarity ahead of the Mayoral Election on 5th May. We hoped that seeing the posts would get people thinking about the housing market as a political issue that they could have some influence on. If they did, we had a handy guide for them.

It was the first campaign of its kind that we have attempted and we could not have done it without the energy of a crack team of volunteers*, the guidance of Paolo Gerbaudo of Kings College London, and the inspiration of Pierre-Emmanuel Lemaire, Yasmina Aoun, Cong Bi and Nicola Lotter of Central St Martin's MA Communication Design course.

It was a huge success, generating our biggest media story to date, attracting hundreds of submissions, and surely contributing at least a tiny bit to the highest ever turnout for a London Mayoral Election. 

Now that the dust has settled, we decided to find out what #ventyourrent taught us.

London has a new Mayor. Sadiq Khan was elected last Thursday with 1.3m votes, the largest personal mandate for any British politician in history. That gives him a lot of clout in implementing his manifesto, whether that's dealing with local councils or the Westminster government. 

Let's remind ourselves what he promised. On our Vote Homes comparison site, Sadiq came in behind the Green Party candidate Sian Berry with more amber policies (ones we felt were okay) than greens (policies we called for). And while he had fewer greens than the Lib Dem, Caroline Pidgeon, he had no policies we thought were terrible (marked red) to Caroline's two (on security and rent levels).

After months of debate and campaigning, the London Mayoral election is imminent. Despite housing being the absolute number one issue of the election, the two frontrunners have not managed to face each other to debate it.

There have been general hustings between Sadiq Khan and Zac Goldsmith, including the Evening Standard and Centre for London debate on 21 April, where, amid heated exchanges on policing, transport and extremism, the only real look-in that housing had simply highlighted the similarities between the candidates: building ambitions, first dibs for Londoners, and refusal to build on the green belt (despite Zac’s desire to paint Sadiq as a park concreter).

The final manifesto we're looking at for Vote Homes is UKIP's Peter Whittle's. Like all the other candidates, Peter recognises that housing is the biggest challenge facing London. But unlike the other candidates, he sees the cause as excess demand, rather than a shortage of supply.

The Respect Party candidate, George Galloway, has set out his manifesto on his home page, and we've updated our candidate comparison on Vote Homes. This is what he is promising London’s renters.

Caroline Pidgeon, Liberal Democrat candidate for London Mayor, has published her manifesto. We’ve taken a look at what she’d do to fix the housing crisis and how she compares with other candidates so far.

The Green Party candidate Sian Berry has already promised to establish a Tenants' Union for London. But what else does she have up her sleeve? She recently published her full manifesto and we've now updated her scorecard on www.votehomes2016.com.

The Conservative candidate for London Mayor, Zac Goldsmith, has published his housing manifesto, and we've updated the Vote Homes policy grid with his offer for London's renters.

As the candidate of the governing party in Westminster, it was always going to be interesting to see if he would go any further than current government policy. One of the biggest divides between the Conservatives and the other parties is on security of tenure, and it's safe to say that Zac has stuck his neck out on this, though we're yet to be convinced that renters will benefit from his proposal.

More than a hundred people came to the Renters’ Hustings on Tuesday to hear candidates from five parties tell us what they’ll do for private renters if they’re elected as London Mayor or Assembly Member – a lively discussion chaired brilliantly by Buzzfeed’s Jim Waterson. All five candidates (Sian Berry: Green, Tom Copley: Labour, Joy Morrissey: Conservative, Zack Polanski: Lib Dem and David Kurten: UKIP) said they are private renters themselves, so perhaps they know how, er, ‘special’ it is trying to survive as a private renter in this city.

We have just updated the Vote Homes policy grid with Sadiq Khan's offering in his manifesto, which was published on 9 March. Also updated are a number of recently announced policies from Caroline Pidgeon.
