What is staircasing?

When you first purchased your shared ownership home, your intention may have been to own it outright one day. Staircasing is the process that allows shared owners to buy additional shares in their home — usually up to 100% ownership.

In most cases, the minimum additional share you can buy is 10%, or 1% if you are on the 2021-2026 model lease. There may be a staircasing restriction and/or a limit on how many times you can staircase. Please contact us for more information on your lease.

When you buy more shares, you will buy them at the current market value. The current market value will be determined by a RICS valuation.

The benefits of staircasing

  • Pay less rent – The more of your home you own, the less rent you’ll pay. If you reach 100%, you’ll no longer pay rent (service charges or estate management fees may still apply).
  • Build equity – The larger the share you hold in your home, the greater you will benefit if its value increases.
  • More mortgage choice – Owning outright gives you access to standard mortgage products with potentially lower rates.
  • Flexibility when selling – Once you own 100%, you can sell your property on the open market (subject to any lease restrictions).
  • Freedom to make home improvements – Full ownership means you can make alterations and improvements (subject to any lease or transfer restrictions).

Before you start

Before deciding to staircase, it’s important to understand the costs involved. You’ll need to cover:

  • RICS valuation fee
  • Your solicitor’s fees
  • Our solicitor's transfer fee (£300)
  • Our administration fee (£50)
  • Any mortgage or lender fees
  • Stamp Duty Land Tax (if applicable).

Your rent and service charge accounts must be up to date throughout the process.

The staircasing process

Step 1 – Check if you can afford to buy more shares

Your first step is to check if you can afford to buy more shares. We've partnered with Stairpay to make this quick and easy. Use the tool below to sign up and get started.

Step 2 – Get your home valued

A RICS-qualified surveyor must carry out an independent valuation of your home. This sets the market value for your new share.

  • Valuations are valid for three months.
  • You’ll need a new or extended valuation if it expires before completion.
  • If you’ve made energy-efficiency improvements, tell your valuer — they’ll record figures with and without these upgrades.

We can arrange the valuation for you, or you can commission one directly. Estate agent valuations aren’t accepted.

Step 3 – Submit your Staircasing Application

Create or sign-in to your Stairpay account to submit your Staircasing application. The application provides us with all the information we need to start the process, including your financial and solicitor details.

Step 4 – Legal process

Once we've received your staircasing agreement, we'll issue a memorandum of sale to our solicitors.

During the transaction, our solicitor will:

  • Answer any enquires from your solicitor
  • Await the mortgage offer (if applicable)
  • Agree a target completion date
  • Prepare the transfer documents (a £300 fee applies).

Step 5 – Completion

Congratulations! You’ve successfully purchased more shares in your home.

We’ll update our records, and you’ll receive your confirmation documents.

Frequently asked questions

How many times can I staircase?

The number of times you can staircase depends on the type of lease you have. Most standard leases allow up to 3 staircasing transactions. Newer 1% leases allow more.

How long does the process take?

We aim to complete within the three-month validity period of your RICS valuation, but this may vary depending on legal or mortgage processes.

Do I need a deposit?

Yes, but you may have enough equity in your property to act as a deposit.

Will I have to pay Stamp Duty?

If you chose to pay Stamp Duty in stages when you first bought your home, further payments may apply when staircasing beyond 80%. If you paid the full amount upfront, no additional Stamp Duty will be due.
