Leasehold: Building an extension – how & when to get freeholder consent

We want to put a single storey extension on our leasehold ground floor terrace property. We have engaged an architect to complete drawings for council planning permission. I am wondering at what point we need to get our freeholder's agreement to make these structural changes? Could we submit for planning permission and once we have that apply for freeholder approval?

Building an extension on a leasehold

Obtaining leaseholder consent for alterations

You have done the right thing in checking your lease to ensure that you are entitled to undertake alterations as long as you have consent.

In this instance, we recommend approaching your freeholders sooner rather than later. By doing so, you can ensure there are no unexpected delays further down the line and also get a better idea of whether you need to budget for additional costs.

For example, there is normally a charge associated with getting the approval (which is normally in the form of a formal Licence for Alterations) and charges for altering the details of the lease to take account of the new extension.

Your freeholder is unlikely to withhold consent but they will want to reassure themselves that the changes you are making represent an improvement. Showing them your plans should help.  They are likely to want to get a professional opinion on them.  If this happens and they, for example, hire a surveyor to look over your plans, they are likely to charge you the costs of doing so.

License for alteration charges

According to Schedule 11 of the Commonhold and Leasehold Reform Act 2002 all charges should be reasonable and a leaseholder has the right to challenge the reasonableness of charges.

Costs could include such items as: surveyors costs of checking plans and the work itself, solicitor costs for drawing up a formal licence and general administration charges.

Knowing what that cost is in advance will allow you to budget and, if necessary, challenge any costs that may be unreasonable.
