Rent reviews and rating assessments

Rent reviews are a mechanism for adjusting a tenant’s rent to the current market level. Similarly, the revaluation of rating assessments adjusts the rates an occupier pays, bringing it into line with rental values.

You negotiate rent reviews (if your lease provides for them) with your landlord. You discuss rates with your local valuation office. The key questions are whether an increase is reasonable and if you should challenge it. This briefing covers:


  1. The rent review terms in your lease.
  2. How to negotiate a low open market rent valuation.
  3. How to appeal against a rent review.
  4. Rating assessments, and how to query your valuation.

1 Your initial position

The landlord’s right to increase the rent, and your right to challenge an increase, are detailed in your lease agreement. Read it, and discuss it with your professional adviser, who should specialise in property.

1.1 The frequency of rent reviews is typically once every three to five years.

  • As a tenant, you want rent reviews to be as far apart as possible. Your rent then lags behind any general increase in rents.

1.2 The new rent is usually the open market rental value at the date of the rent review.

  • This is the rent the landlord could expect to receive if the premises were leased to a third party, on similar terms.
  • You may have agreed a low rent for the original lease, but this is irrelevant. It does not entitle you to continue with a low rent.

Some leases have fixed increases or link the new rent to increases in the retail price index or some other inflationary indices.

1.3 If the rent review is ‘upward only’, the rent cannot go down at the rent review even if the open market value of the rent is lower than your existing rent.

1.4 The lease will include a range of ‘assumptions’, aimed at making comparisons with other premises easier when deciding the open market rental value. The ‘use of the premises’ assumption can increase or decrease the rental value.


  • If a building can be used either as high-value office space or low-value storage space, the rent will be valued on the assumption that the tenant will use it as an office. It is irrelevant that the tenant may really only be using it for storage.

1.5 The landlord must usually give you notice, in writing, if the rent is to be reviewed. Three months is a typical notice period.

  • This gives you a chance to decide if the proposed increase is reasonable (see 2).
  • If you decide an increase is unreasonable, inform the landlord in writing immediately. Give your reasons.
  • There may be a deadline for replying.

    If you miss it, you may have to pay the new rent.

2 Negotiating a market rent

At a rent review your landlord will want to increase the rent. Strengthen your position by gathering evidence to show that the proposed rent is too high.

2.1 Collect information on the rents charged for similar premises in the area.

  • Ask fellow tenants what they are paying.
  • Commercial estate agents can provide details of properties to let.
  • Obtaining details of the rents that have actually been agreed is more difficult. You may be able to reach an agreement to swap information with the tenants.

2.2 Form your own estimate of the open market value of your premises.

  • When analysing the rent of other premises, make any necessary adjustments for incentives (or premiums).

2.3 Try to reach a settlement with your landlord at this stage.

  • If local rent levels are collapsing, consider proceeding more slowly. But observe any time limits set out in the lease.
  • If you are in shared premises, consider negotiating jointly with other tenants.

Until agreement is reached, you can continue paying rent at the old rate. On settlement, you will have to pay the difference between the passing and revised rents.

2.4 If appropriate, negotiate better terms in your lease as part of your rent review.

Your surveyor can compile the necessary evidence and negotiate on your behalf.

If the negotiations become acrimonious or legalistic, involve your solicitor.

3 Using a third party

If you cannot agree the new rent, the lease usually specifies that a third party should resolve the dispute and sets out the procedure to be followed.

3.1 First try to agree on an independent third party, such as a local chartered surveyor.

  • You can veto the landlord’s suggestion, if you think this person favours the landlord.
  • If you cannot agree the appointment, an independent appointment must usually be made by the president of the Royal Institution of Chartered Surveyors (RICS).

3.2 An arbitrator’s decision will be based on evidence presented by you and the landlord.

  • Your professional adviser can help you build and put forward a strong case.
  • The arbitrator decides how the fees and costs of the parties should be apportioned.

    If there is a clear loser who is seen to have been unreasonable, that party could be ordered to pay the full costs.

3.3 An independent expert’s decision will be based on his or her own knowledge and investigations.

  • The independent expert need not consult you or the landlord.
  • Usually you split the fees equally with the landlord and pay your own costs, even if you win the appeal.

3.4 The major drawback of going to a third party is the cost, as well as the time.

  • The fees are usually agreed by you and the landlord with the third party when he or she is appointed.
  • You can expect to pay at least £2,000, plus the cost of your own professional advisers.

  • The third party’s decision is usually announced once the fees have been paid.

Going to a third party may not pay off, especially if your rent is low. But it may be the only way to reach an agreement.

3.5 Once the third party’s decision is made, any rent owed is payable immediately.

  • The new rent is backdated to the rent review date. Interest is likely to be payable.

3.6 The alternative way to settle a rent dispute if your lease allows it, is to use a mediator. You and your landlord need to agree who the mediator will be.

  • Using a mediator may be a quick and cheap solution. The mediator has no authority to impose a rent on either party.

4 Understanding rates

4.1 All non-domestic property is subject to business rates.

  • Living accommodation - including most accommodation within business premises - is subject to council tax.
  • Business rates are normally payable by the occupier of the premises.
  • If your lease or licence agreement states that the rent is inclusive of rates, it is your landlord who is responsible for paying the rates. If the landlord defaults, the local council can pursue the occupier.

4.2 The amount you pay in rates is based on the rateable value of your premises.

The Valuation Office Agency (VOA) in England and Wales, and the Assessor in Scotland, provides summary valuations showing how your rateable value has been calculated.

  • The basic level of rateable value usually remains fixed for a five-year period. The current rateable values are based on open market rental values on 1 April 2008.
  • Any new premises or any changes to existing premises are valued at the rent they would have commanded in April 2008.
  • The next revaluation comes into force on 1 April 2017. Any national increase in rateable values should be offset by a comparable reduction in the multiplier (see 4.3).
  • The rateable value is the same, whether the premises are owner-occupied, leased or licensed.

4.3 The normal rates payable are calculated by multiplying the rateable value by the multiplier. The multiplier (sometimes called the Uniform Business Rate or UBR) usually changes each year in line with inflation.

  • From 1 April 2016, the standard multiplier in England is 49.7p. So for a building with a rateable value of £50,000, the annual rates would normally be £24,850 but this could be subject to transitional arrangements (see 4.6).
  • A lower small business multiplier, 48.4p, is used for businesses eligible for Small Business Rate Relief (SBRR) (see 4.4).Special rules apply in the City of London, which usually charges a small supplement over the standard multiplier.
  • Separate multipliers apply in Wales, Scotland and Northern Ireland.

4.4 Businesses in England which occupy only one main property with a low rateable value can get SBRR.

  • Eligible rate payers automatically qualify for 100% SBRR on buildings with a rateable value up to £6,000 and a tapering relief from 100% to 0% for properties up to £12,000.
  • SBRR will be permanently doubled from April 2017 to £12,000 with tapering relief for properties valued up to £15,000.
  • For rateable values between £12,000 and £17,999 (or up to £25,499 in London), there is no percentage reduction but the small business multiplier is used. The threshold for the standard business rate multiplier will rise to £51,000 from April 2017.
  • Businesses that occupy additional properties may still be able to claim the relief on the main property, provided that the rateable value of each of the other properties is less than £2,600. 


You must inform your local authority if your circumstances change in any way that is likely to affect your entitlement to SBRR, for example, moving to new premises.

4.5 You may qualify for other reliefs:

  • If the property (or part of the property) is empty.
  • Retail premises with a rateable value up to £50,000 may receive a business rate discount of up to £1,500.
  • New occupants of previously vacant retail premises moving in between 1 April 2014 and 31 March 2016 receive a 50% business rate discount for the first 18 months.
  • Empty commercial premises are exempt from business rates for three months. Industrial and warehouse buildings qualify for a further three months’ exemption. After that, full business rates are payable.
  • Businesses that start up in, or relocate to an enterprise zone before March 2018 qualify for a 100% business rate discount for five years up to a maximum £275,000.
  • Listed properties and those with a rateable value of under £2,600 are exempt.
  • Certain agricultural properties, those used for religious worship, the welfare and training of disabled people, charities and qualifying amateur sports clubs also qualify for reliefs or exemptions.
  • You may also receive a temporary reduction if your business is affected by severe local disruption (such as flooding or major roadworks).

You can check whether you qualify on the GOV.UK website or by contacting your local authority.

4.6 Your local authority will send you a rates bill each year. You have a choice of when to pay.

  • Most businesses pay in ten equal instalments.

5 Challenging your rates

5.1 If you disagree with your premise’s rateable value, contact your local VOA office to discuss the valuation and why you think it is incorrect.

5.2 If you still do not agree with the rateable value, you can make a formal proposal. There are two main grounds of appeal:

  • The rateable value of the premises is significantly different from the open market rental value of the premises at the last valuation.
  • The premises are adversely affected by a change in circumstances. For example, structural alteration of the premises or the loss of nearby parking facilities.

    You can only make one proposal on the same grounds during the life of a rating list (the current list runs until 31 March 2017).

5.3 The VOA will consider your proposal and discuss it with you.

  • You can complete the proposal yourself, or on the VOA website or by contacting them directly or 03000 501501).
  • A property adviser, such as a chartered surveyor, can advise you and make a proposal on your behalf.
  • Avoid dodgy advisers who may charge large fees in return for poor advice. Try and use an adviser based on a personal recommendation.
  • The VOA will advise you when they are ready to discuss your proposal.
  • If you cannot agree a revised assessment, you can appeal to a valuation tribunal.

5.4 If your rates challenge is successful, you receive a rate refund.

  • This might be a repayment, a reduction in your monthly payments, or a credit for the next year.
  • You usually receive interest on the amount owed to you.
