英国增值税，标准税率 20%。中介、律师费都要加。
报价分含税与不含税两种：中介报 2% 不含税，实际是 2.4%。本字段默认 2.4%，已含税。
拿报价时务必问清——£50 万成交上相差约 £2,000。
UK sales tax, standard rate 20%. Agency and legal fees all carry it.
Quotes are either inc VAT or plus VAT: an agent quoting 2% plus VAT actually charges 2.4%. This field defaults to 2.4%, already inclusive.
Always confirm which basis — on a £500k sale the gap is about £2,000.

Repairs that restore the property: redecorating, roof repairs, a like-for-like boiler. Extensions and added rooms are improvements (field on the left).
