Scope & Pricing Notice:
All prices are based on standard drawings and documentation typically required for the stated project size. If additional, complex, or bespoke requirements are provided — such as detailed specifications, multiple design options, or advanced schedules — we’ll review these and offer a bespoke quotation to reflect the expanded scope. Any change in fee or turnaround time will always be confirmed before work begins.
£99 Quote Review Case Study
This £12,900 electrical quote looked normal, but our £99 Review found the items only added up to £9,800, a £950 mistake. We also uncovered duplicated circuits, vague provisional sums, and overpriced fittings. The homeowner walked away £2,000+ better off. That’s a 20x return on a £99 check.
£199 Quotation Comparison Case Study
This homeowner invested £199 in our Quote Review. Contractor A quoted £62,160, Contractor B £56,400. By requesting trade-by-trade breakdowns, we exposed padded sums, found the best value rates per trade, and cut overlaps. The result: £7,500+ saved and the right builder secured.
£299 Feasibility Check
We reviewed the planning drawings and carried out an in-depth cost summary of the proposed double extension. By breaking down each element and advising the clients on choices for every item, Costable ensured they achieved the best value for money. This gave our customers confidence that their budget could deliver the works, all for just £299.
