Lease Extension Costs

A leaseholder should consider the following factors when establishing the total lease extension costs:



Leaseholders commonly forget to factor in the additional costs (aside from the landlord's premium) at the outset. It's important to keep these costs in mind when negotiating the premium with the landlord.

Fees are different for both statutory route and informal route lease extensions. The Informal Route tends to be slightly cheaper, but generally speaking a lower premium can be achieved through the formal statutory route.

Informal Lease Extension Costs

The chart below illustrates these costs based on a premium of £15,000 agreed informally, outside of the statutory route. In this scenario, additional expected costs make up almost 15% of the total expected costs. The lower the premium, the higher the percentage of additional costs.

If the premium is considerably lower, the additional costs become much more significant. Take a look at the pie chart below:

In the above example the additional costs equate to almost half of total costs.

Leaseholder's informal route legal costs

Typically a leaseholder can expect to pay on average around ££900 + VAT in legal fees. On top of that, some mortgage lenders will charge an administration fee in order to deal with signing the documentation (a requirement). These fees usually don't exceed £105.


Landlord's informal route legal costs

As leaseholders are obliged to pay for the landlord's reasonable legal fees (a statutuary right) it's likely that the landlord will not 'shop around'. This results in the landlord's legal fees being significantly higher than the leaseholder's. Expect to pay in the region of £1000 to £2000.


Landlord's other costs

Statute allows the landlord to recover other reasonable costs, such as appointing surveyor to carry out a valuation. Typical valuation fees are around £400.


Landlord's premium

The leaseholder must pay the landlord a premium for the privilege of extending the lease term. This compensates the landlord for the diminution in the freehold value, as well as lost ground rent (as usually the ground rent is reduced to nil for the remainder of the term. You may wish to instruct a professional surveyor to give you an accurate assessment of the expected premium, or otherwise rely on an online Lease Extension Calculator if you have an accurate estimate of the value of your property..


Total additional lease extension costs (informal route)

Setting aside the premium, we can see that additional costs are expected to be in the region of £2,100 to £3,200 when following the informal route.

Statutory Lease Extension Costs

Lease extension costs tend to be slightly higher on stattory lease extensions, however this is usually offset by achieving a lower premium. The chart below illustrates these costs based on a premium of £15,000 set by the leasehold tribunal, after a hearing. In this scenario, additional expected costs make up almost 25% of the total expected costs. The lower the premium, the higher the percentage of additional costs.

As you can see, 25% of total expected costs are now spent on total costs. If the premium is considerably lower, the additional costs become much more signifant as illustrated below:

In the above example the additional costs equate to a huge 61% of total costs. Now let's look at how these costs are broken down.

Leaseholder's legal costs (formal route)

Costs tend to vary widely, however on average a leaseholder can expect to pay around £1,500 in general, however this increases if the matter proceeds to a tribunal.


Landlord's legal costs (formal route)

Under current law Section 60 of the LRHUDA 1993 Act, the leaseholder pays the freeholder's legal costs however the costs have to be reasonable.

What are reasonable section 60 costs?

Unfortunately the law is wide open in this regard. Whilst some freeholders take advantage of this generally speaking leaseholders should expect to pay around £1,200 to £2,000.


Landlord's other costs (formal route)

Statute allows the landlord to recover other reasonable costs, such as appointing surveyor to carry out a valuation. Typical valuation fees are around £400 - £800.
