Artificial intelligence (AI) writing tools, such as ChatGPT, Gemini, and Claude, have become extremely popular. They can create emails, write marketing content, and debug code quickly. Many people think these tools could replace traditional editing tools. A spell checker, once a key part of word processors, might seem unnecessary now that AI can rewrite a paragraph with correct grammar and style.

It would be a mistake to get rid of human-verified editing tools. Current AI services are strong suggestion engines, but they are not always correct or truthful. If you rely only on AI for accuracy, you could make significant errors that a basic spell checker would easily catch.

The Problem with “Hallucinations”

A main issue with current AI models is “hallucination.” AI predicts the most likely next word in a sequence. This usually results in fluent, relevant text. However, when the model lacks information or the prompt is unclear, it creates believable-sounding falsehoods.

A standard spell checker checks if a word is in the dictionary and used correctly. An AI might “correct” a technical term to a common synonym, which changes the meaning of a sentence. It might make up statistics, quote sources that do not exist, or include names of people who were not involved in an event. These errors often sound correct but are factually wrong.

Context is Key (and AI Can Miss It)

Consider a business communication where a specific internal acronym is vital. A traditional spell checker might flag the acronym but offers the simple option to “Add to Dictionary.” An AI, trained on large public datasets, might try to “fix” that unique term with a generic, incorrect replacement because it’s unfamiliar with a specific context.

AI also struggles with nuance, tone, and the legal or compliance requirements of specific industries. A human editor or a dedicated, rule-based editing suite understands the fixed rules of internal policy or legal jargon.

A Powerful Partnership, Not a Replacement

AI is a strong first-draft generator and brainstorming partner. It speeds up the creative process and helps with writer’s block. However, it does not replace the crucial final step of human review and verification.

Use AI as a smart assistant, not the editor-in-chief. Keep traditional spell checkers, grammar tools, and critical thinking skills sharp. The best method in 2025 is not AI instead of spell check; it’s AI plus careful human oversight. Do not get rid of a spell checker; it’s the last defence against convincing, and incorrect AI output.

A demerger involves splitting the trading activities of a single company or group into two or more independent entities. This can be facilitated by distributing the assets of a holding company to its shareholders.

There are special statutory demerger provisions that are designed to make it easier to divide and put into separate corporate ownership the trading activities of a company or group of companies. An exempt demerger will be deemed to occur under these provisions. As a result, the distribution is typically exempt from Income Tax and usually does not trigger any Capital Gains Tax, as the gains are effectively rolled over.

The provisions do not apply where a trading activity is to be sold or becomes owned by a person other than the existing member of the original company.

The provisions allow for the removal of the distribution charge in appropriate circumstances, making the distribution an ‘exempt distribution’. This applies to trading activities only. Companies that utilise the demerger provisions range from small private businesses to some of the largest public companies in the UK.

The legislation also provides for a clearance procedure. Under this a company that wants to demerge trading activities can obtain advance confirmation from HMRC that the distribution that will arise will be an exempt distribution.

The Chancellor has kept the main pension allowances unchanged but has confirmed a new cap on salary sacrifice arrangements that will apply from April 2029.

There had been heated speculation that the Chancellor would change the pension rules to help the government raise taxes, but no changes were announced to the annual allowance (which remains at £60,000) or to the carry-forward rules which can use up previous year’s annual allowances. The lump sum allowance has also remained unchanged at £268,275.

However, the Chancellor announced changes to the salary sacrifice arrangements for pension contributions. Salary sacrifice allows employees to reduce part of their salary or bonus in exchange for pension contributions, which is tax-efficient and helps save for retirement. However, this arrangement has disproportionately benefited higher earners with salary sacrifice costs expected to rise from £2.8 billion in 2016-17 to £8 billion by 2030-31.

From April 2029, the government plans to introduce a cap on salary sacrifice contributions which will limit the amount that can be sacrificed without incurring National Insurance Contributions (NICs) to £2,000 per employee. Salary sacrifice contributions above this amount will be subject to employer and employee NICs. Pension contributions that are not part of a salary sacrifice will remain unchanged.

The Chancellor reaffirmed the government’s commitment to maintaining the Triple Lock on the State Pension throughout this parliament. This means that in April 2026, the State Pension will increase by 4.8%. The Triple Lock ensures that the State Pension rises by the highest of three measures: inflation, wage growth, or 2.5%, helping to protect pensioners’ income against rising costs of living.

Also, starting from 6 April 2027, the government will close a loophole that allows individuals to use pensions for inheritance tax (IHT) planning. Under the new rules, any unspent pension pots will be brought within the scope of IHT.

The Chancellor of the Exchequer, Rachel Reeves announced increases to the Minimum Wage rates on the eve of the Budget. The Chancellor confirmed that the government has accepted in full the proposals of the Low Pay Commission (LPC) for increasing minimum wage rates from 1 April 2026.

The National Living Wage (NLW) rate will increase from £12.21 to £12.71 on 1 April 2026 and represents an increase of 50p or 4.1%. The NLW is the minimum hourly rate that must be paid to those aged 21 or over. The increase represents a pay rise of £900 a year for someone working full-time and earning the NLW.

It was also announced that the National Minimum Wage (NMW) – for 18-20 year olds – will increase from £10.00 to £10.85 an hour. This is an 8.5% increase and will see younger workers having their pay boosted by up to £1,500 next year. This increase is part of moves to narrow the gap in wage rates for 18-20 years olds and the NLW and ultimately create a single adult wage rate for all those aged 18 and up.

The NMW rates for 16 to 17 years old will increase from £7.55 to £8.00 – an increase of 45p or 6% per hour – from next April. The Apprentice Rate will mirror this increase in line with earlier recommendations by the LPC.

At the Budget, the government also announced two new measures aimed at supporting young people’s employment and skills development.

1. The Youth Guarantee: Jobs Guarantee Scheme will provide a six-month paid work placement for eligible 18-21 year group, who have been on Universal Credit and searching for work for at least 18 months. This scheme will cover 100% of employment costs for 25 hours a week at the minimum wage, alongside other support measures.
2. The Youth Guarantee and Growth and Skills Levy will allocate more than £1.5 billion over the spending review period to improve employment and skills support. This funding will help ensure that young people have access to high-quality training opportunities and streamline the apprenticeship system to make it more efficient.
