What dematerialisation means

Dematerialisation means the share no longer exists as a paper certificate, only as an entry in an electronic register. In the UK that is the CREST system, an electronic register of shares and shareholders through which shares are transferred electronically. Buy on the stock market today and you almost never receive paper. On AIM it is even a rule: shares there must be eligible for electronic settlement.

Alongside that, there are still shareholders today who hold their shares directly and on paper, with a certificate in a folder. That is the part now set to disappear.

What the government has decided

It began with the Digitisation Taskforce chaired by Sir Douglas Flint. Its final report of July 2025 recommended a staged approach: first move paper registers to digital registers, then improve the intermediated system through brokers and platforms, and finally move all shares there. The government accepted this plan in three steps.

For the first step, the Dematerialisation Market Action Taskforce (DEMAT), chaired by Mark Austin, published its implementation plan on 14 July 2026, and the government accepted it. It intends to require by law that all publicly traded UK companies keep digital share registers and that paper shares in those companies no longer count as proof of ownership. The legislation is due to take effect before the end of 2027; the government will announce the exact date.

The three steps at a glance

This is how the taskforce and the government describe the road. Only the first step has a timeframe so far.

What it means for shareholders

For shareholders holding paper certificates, the key news is that they need do nothing in the first phase. Companies and their registrars organise the change, supported by DEMAT, and shareholders' rights are unaffected. The certificate in the safe deposit box does not become worthless; it simply stops being the proof. The proof is the entry in the digital register.

Before the final step, full intermediation, the government is to set criteria first. The needs of older and vulnerable investors are named expressly. If you hold your shares directly today and want to keep it that way, you have time, but not for ever.

What it means for your PLC

The announced duty applies to publicly traded companies. If your PLC is not quoted on a trading venue, the government response means nothing changes for it directly in this first step. With a listing, though, the topic becomes yours at the latest, because a clean register capable of electronic settlement is then part of the basic kit anyway.

From the company secretary's side the preparation is unspectacular, and yet it is what everything hangs on: every transfer in the register documented, every share class unambiguous, every address current. The share's identifiers, the ISIN in particular, should be settled. How to obtain them is under LEI and ISIN. DEMAT also intends to publish operational standards for digital share registers. Once they are out, we align your PLC's register keeping with them.

Transfers and stamp duty: what stays the same

Dematerialisation changes how ownership is proved, not whether a transfer is taxed. Buy existing shares electronically through CREST and you pay Stamp Duty Reserve Tax, deducted automatically. Transfer outside CREST and the tax is still due, only nobody deducts it automatically, and HMRC has to be told in writing.

In PLCs with few shareholders who move shares between themselves, this is often forgotten. A digital register makes such transfers more visible, not tax-free. Rates and exemptions are collected under UK PLC tax.

FAQ

Common questions about dematerialisation of shares in the UK

Will my paper shares in a British company become worthless?

No. Your rights are unaffected. Under the new law, though, the entry in the digital register rather than the certificate is to count as proof.

Do I need to do anything as a shareholder?

Not in the first phase. Companies and their registrars organise the change and inform shareholders.

When does it apply from?

The legislation is due to take effect before the end of 2027. The government will announce the exact date.

Does it apply to an unquoted PLC too?

The government response refers to all publicly traded UK companies. No duty is announced for companies that are not traded in this first step.
