Welcome to Radius Consulting

Helping landlords & tenants in dilapidations disputes by providing expert diminution valuation advice.

Diminution valuation is the term which describes the legal limit, or cap, on damages paid in dilapidations disputes.

Tenants need a Diminution Valuation (DV) by a valuer, to ensure that the Cost of Works settlement negotiated by their chartered building surveyor, even when considerably less than initially claimed by the landlord, is not more than should actually be paid out.

Landlords too often need a DV, also known as a Section 18 Valuation, either to rebut an opportunistic one presented by a tenant or as is required by the Dilapidations Protocol

Every landlord and tenant will be concerned with dilapidations matters at some point during, and invariably at the end (break) of, a lease. Most leases make tenants responsible for all repairs, redecorating and reinstating any alterations they have made. The landlord is entitled to damages for any of these works not done by the lease end. The extent and pricing of these works are assessed by a chartered building surveyor and listed in an Excel document which becomes the Schedule of Dilapidations (Quantified Demand) ‘served’ on the tenant by the landlord’s solicitor. The tenant usually employs their own chartered building surveyor to negotiate a lower total sum for settlement.

As noted above, whilst dilapidations are usually then settled at the costed repairs figure negotiated between opposing chartered building surveyors, with tenants pleased that it is far less than originally claimed by the landlord, it will probably still be far higher than it should be.

The law provides that landlords should only be compensated for their true loss, which is the lower the Cost of Remedial Works or the impact on the property’s value. The chartered building surveyors negotiate the Cost of Works only; they are not qualified to assess the impact (if any) on the property’s value. This is the unique domain of a totally different discipline of a chartered surveyor, being a chartered valuation surveyor (also known as a Valuer, or GP surveyor).

Commonly the impact of disrepair etc. on a property’s value is far less than even the lowest Cost of the Remedial Works negotiated by the tenant’s chartered building surveyor. This differential is caused by a range of factors, including that older buildings are worn and so not required, or expected, to be like new, and that whilst a landlord might not admit it for fear of undermining their dilapidations claim, the property requires modernising and upgrading anyway, which works probably erase (supersede) a lot of what they are claiming for.

Researching and arguing these points to further minimise the dilapidations settlement figure, is the specialism of the chartered valuation surveyor (Valuer).

A tenant settling a dilapidations claim without this Diminution Valuation (DV) advice by a Valuer is more likely than not to be paying too much.

As detailed and explained at Damages Cap, the law which minimises dilapidations payments to the lower of the Cost of the Remedial Works or the impact on the property’s value is, in England & Wales, provided by Section 18 (1) of the Landlord & Tenant Act 1927. A similar statute applies in Ireland, whereas a relatively weaker (but still very worthwhile) measure of ‘alternative loss’ applies at common law in Scotland.

Whilst this may all seem very tenant-focused, landlords require DV advice too.

Landlords require DVs in situations including:

To rebut an opportunistic DV presented by a tenant;

If not (yet) doing the Remedial Works, for whatever reason, then a DV must be provided to support and evidence any dilapidations claim (this is required by paragraph 9.4 of the ‘ Dilapidations Protocol ’).

We aim to shed more light on what is sometimes termed the ‘dark art’ of DVs on this website. We are consistently reviewing and updating, with the aim of improving understanding and access. If you have the time, the Articles and Case Studies will all inform, with Dilapps - our App available for free at both App Stores - providing a quick, user-friendly tool to assist in appreciating the likely benefit a DV would have in your own case.
