A London address.
An individual story.
KnokKnok is a founder-led estate agency advising sellers in Chelsea, Belgravia and the surrounding prime London neighbourhoods. We bring together property valuation, campaign presentation, qualified viewings and negotiation.
Begin with the home and your plans. A house on a quiet Chelsea street, a Belgravia mews and a garden-square apartment call for different evidence, buyers and decisions about exposure.

A clearer view
of the market.
Read the evidence, then ask what it means for your particular home. London-wide statistics cannot value an individual prime property.
04 / Before you decide
Good questions.
Clear answers.
Estate agency and campaign guidance from KnokKnok. For the legal details of your sale, speak with your conveyancer.
How do I choose an estate agent for a high-value London home?
Ask who will handle the valuation, viewings, buyer qualification and negotiation. Review relevant campaign examples, the evidence behind the proposed price and a written plan for reaching suitable buyers. Agree fees, agency terms, reporting and the approach to privacy before instructing.
Can KnokKnok sell my Chelsea or Belgravia home privately?
Yes. Mark can discuss a private, targeted or public launch. Agree which photographs, price details and particulars may be shared, with whom and when. A private approach limits exposure, so agree a review point and how you will judge the response.
What will a Prime Central London valuation take into account?
The precise street and building, usable floor area, layout, condition, light, outside space and ownership details. Asking prices show the competition; completed sales provide different, dated evidence. For apartments, the lease, service charges, lift access and planned works also inform the discussion.
Can you help if I live abroad or my property is already listed?
Yes. Tell Mark about your timetable, access arrangements and any current instruction. For an existing campaign, share the listing, price history and viewing feedback. Your current agency agreement and notice requirements should be checked before a new instruction is arranged.
Does requesting a valuation commit me to selling?
No. The initial conversation is without obligation. It helps establish your plans, the information needed and whether a visit would be useful. It does not authorise photography, advertising or a public listing.
