Estate agent fees in CT21 typically range from 1-3% plus VAT (1.2-3.6% total), with the national average around 1.5% plus VAT. Don't accept the first offer - negotiate based on the agent's track record, market share, and your specific property requirements. Given the CT21 average asking price of £480,324, a 1.5% fee would amount to approximately £7,205 plus VAT. For properties valued over £750,000, you have additional leverage to negotiate lower percentages since the total commission remains substantial.
