Serving the Section 42 Tenant’s Notice

Before your Section 42 notice is drafted, one of our firms of specialist chartered RICS surveyors will value your property for the purpose of the lease extension and identify the likely ‘premium’ (the price of your lease extension) you will pay your freeholder. For more information on the valuation process for the purpose of a lease extension please see here.

Identifying Your Competent Landlord

Our specialist lease extension solicitors for Southwark will also identify the ‘competent landlord’ whose interest in the property is long enough to grant your 90-year lease extension.

Sometimes, this will be the direct landlord or housing management to whom you pay your service charge or ground rent. However, the competent landlord is often the freeholder of the building.

The Leasehold Reform Housing and Urban Development Act 1993 requires leaseholders to serve a Tenant’s Notice (Section 42 notice) on the ‘competent landlord’.

The Section 42 notice commences the lease extension and must include certain key legal information. This is a technical legal notice, and it must be correctly drafted and validated to ensure your lease extension is deemed valid.

At The Lease Extension Company, we work with the leading specialist legal firms in this specific area of law, ensuring that your notice is drafted and reviewed by leading experts in this field. The Section 42 notice will be sent to you for approval before it is forwarded to the solicitors, who will serve the notice to the Freeholder on your behalf.

Key Freeholders in Southwark:

One of the main freeholders in Southwark is Southwark Council, which is landlord to around 15,000 leasehold properties within a portfolio of roughly 52,000 homes, making it the largest local authority landlord in London. Other key freehold interests include Peabody, London and Quadrant, Hyde and Southern Housing.

Finding Your Freeholder:

The details of your Freeholder will be cited in your original lease. If you’re missing this document, you can get a copy of your leaseholder agreement by contacting HM Land Registry for a small fee. As a client of The Lease Extension Company, we will arrange this for you.

How Much Will Your Lease Extension Cost?

Your premium is calculated based on the following factors:

• The value of your property.
• The amount of ground rent you pay and how much it increases over time.
• The number of years remaining on your lease.

The cost can also depend on your route to obtain your lease extension.

• Informal Lease Extensions: Costs are determined and agreed upon directly with your freeholder.
• Statutory Lease Extensions: You are responsible for the valuation and legal costs of both you and your freeholder, plus the premium for the additional years on your lease.
