Thinking of selling your home? You'll need a BASPI

Published 16th of June, 2022


The Buying and Selling Property Information (BASPI) form has been designed to be a single source of truth for the upfront information required about a property when it is being sold.

The BASPI should be completed at the same time as the property is put on the market for sale.

By having all the information you need to buy and sell a home in one place at the time the property is first marketed for sale, the sale process should be less stressful, quicker to complete, and less likely to fail or fall through. The aim of the BASPI is to make the process of buying and selling your home less stressful.

What is a BASPI?

A BASPI is the Buying and Selling Property Information (BASPI) form. It has been designed by the Home Buying and Selling Group. It collates all the information you need to sell your home in one place.

The latest version of the BASPI was released in April 2022

Why do we need a BASPI?

Housing purchases and sales often fall through after an offer has been accepted due to a lack of information provided to the buyer from the seller. It often takes so long to collate all the information that the buyer is unable to complete the sale in a practical time frame and so the sale fails to complete. Every failed housing transaction usually means that a lot of time and money has been wasted, time and money that is very difficult to get back.

By having all the information you need to sell your home in one place when you put your home on the market for sale, the buying and selling process can be speeded up and completed more easily reducing some of the risks that the purchase and sale will fall through.

What is the Twindig BASPI?

Twindig has merely taken the Home Buying and Selling Group’s BASPI and digitised it to make it easy to complete.

Twindig also allows you to upload the supporting documents required by the BASPI. When a homeowner has completed their BASPI on Twindig we place the form itself and all the supporting documents in an easily shareable ‘BASPI bundle’.

The BASPI bundle allows you to share the complete BASPI and supporting documents with those who need to see it such as conveyancers, mortgage providers and the potential buyer of your home.

One in three housing transactions fall through why take that risk?

Around one in three housing transactions fail to complete after getting to the Sold Subject to Contract (SSTC) stage, often the collapse is due to material facts about the property not being known until late in the home buying or selling process. The BASPI seeks to reduce those fall through risks by making key material information about the home known upfront, before too much money has been spent on a transaction that is unlikely to happen. A case of forewarned is forearmed.

How does the BASPI speed up housing transactions?

The BASPI speeds up housing transactions by helping you get all the documents you need in order to sell your home (or buy your next one) ready and in one place. The Twindig BASPI can be digitally shared with other key parties such as your conveyancer or solicitor, this saves documents from getting lost in the post or hidden under a pile of other documents on your solicitor's desk. The quicker your home purchase or sale gets to exchange the lower the risk of your housing transaction falling through and the more likely you are to move. For,s like the BASPI may be dull, but they do get you moving to the house you want to live in.

Whilst not technically part of the BASPI the documents upload section has been added by twindig to make it easier to collate all the information you need to buy and sell your home in one place.

As you answer questions in BASPI Part 1 and Part 2 your answers may require you to upload certain documents - such as warranties and guarantees, these documents can be uploaded in Part 3 of the Twindig BASPI.

Once you have completed your BASPI form on twindig you will get a chance to review it and check that you have uploaded all the required documents. Once you have signed off the BASPI Twindig generates a BASPI bundle (a copy of your BASPI form and the related documents) which can be shared as and when required with relevant parties such as conveyancers and solicitors. 

What is the difference between a BASPI and a property logbook?

Good question a BASPI contains all the information you need to sell your home, whereas a property logbook has all the information you need to manage your home. You can think of a property logbook as a combination of your home's user manual and full-service history.

A good property logbook will contain all the information you need for your BASPI, so putting the time into a property logbook now will save you time later when you come to sell your home

What is the Home Buying and Selling Group?

The Home Buying and Selling Group is an informal mix of experts and practitioners from across the legal and financial sectors who are working together with the UK Government (the Ministry for Housing Communities and Local Government) to try to improve the home buying and selling process for home buyers and home sellers. The Group meets once a quarter.
