THE PROPERTY FILTER TAKE
Chris Philp, the Conservative MP for Croydon South, has launched a petition against plans for 5,600 homes on Croydon green belt land and is challenging the London Plan's housing target for the area between Croydon and New Addington (PropertyWire, 7 September 2026).
An allocation decision moves what land and homes in those postcodes are worth long before anything is built, and any gain you make on the way through is taxable.
Consider modelling the purchase tax before you buy into the corridor, and speak to your accountant about how you hold it.
Plans for 5,600 homes on Croydon green belt land are being contested by the area's own MP. Chris Philp, the Conservative MP for Croydon South, has launched a petition against the scheme (PropertyWire, 7 September 2026). He is challenging the London Plan's housing target for the land between Croydon and New Addington. On the surface, a planning fight. Underneath, a question about land value, and that is where your tax bill starts.
What does a green belt allocation do to land values?
Green belt is land where planning policy restricts development. Allocating it for housing changes what it is worth long before a brick goes down. The London Plan is the Mayor of London's spatial development strategy, so this is England-only policy, and London policy specifically. Neither side has won yet: the plan carries a target, and the MP is petitioning against the number of homes attached to it.
Every amount below is illustrative, not taken from the source. Buy a house in that corridor for £400,000, and a 10% move in values either way is £40,000 on or off your eventual gain. Capital gains tax is charged on the profit when you sell, so a swing of that size changes what you owe. The rate turns on your income and your ownership structure, which our guide to property business structures covers.
Does buying land cost the same tax as buying a house?
No, and in a growth corridor the difference matters. In England, stamp duty land tax (SDLT) is the tax due when you complete a property purchase. Bare land and a dwelling sit on separate rate tables, and a surcharge can apply on an additional dwelling. Scotland charges land and buildings transaction tax (LBTT) and Wales charges land transaction tax (LTT) under their own rules. Croydon is in London, so the England rules apply.

Rates and thresholds move at every fiscal event, and none appear in the material available for this story. So I am not quoting figures I cannot source. Our free property resources hub carries the background reading.
A petition is not a planning decision, and no decision date appears in the source material. If you are weighing an entry into that corridor, our property investment strategies hub covers how to price this kind of uncertainty. Speak to your accountant before you price in a value you expect but cannot yet date.
