A useful conservatory budget is a scope ledger, not one national average. Record the date, location, dimensions and specification behind every figure, then add work that headline package prices may omit.

Budget by workstream

Workstream Possible items
Design and approvals Surveys, drawings, applications, inspections
Site and structure Access, clearance, drainage, foundations, base
Envelope Frames, glazing, roof, doors, ventilation
Services Electrical work, lighting and suitable heating
Finish Plastering, flooring, decoration and making good
Completion Waste, snagging, certificates and contingency

Use written quotes for the current project. Keep allowances visibly separate from fixed prices and ask what happens if ground conditions or existing drainage differ from assumptions. A contingency is not a substitute for defining scope.

FAQs

Are foundations and electrics included in advertised prices?

Sometimes, but never assume so. The quotation should state quantities, specification, labour, approvals, VAT and exclusions.

How should I allow for site-specific work and contingency?

Price known work where possible, list unresolved risks and agree how variations will be authorised. Choose a contingency based on uncertainty rather than a generic promise.

Suggested component

A configurable budget builder using GBP, USD, CAD, AUD or EUR, with dated user-entered figures and no fabricated average.
