PLANNING & COSTS · WORLDWIDE PLANNING
Compare home-adaptation quotes without missing costs
Compare an agreed scope, not just the headline price.

Two quotes can look similar while covering different work. Before comparing prices, write a shared brief: the assessed need, the space, the proposed work and the constraints. This is a project-planning aid, not a construction specification.
DIY versus installed cost: check the missing scope
A shelf price is not a complete installation quote. This comparison separates observations you can record safely from questions for an assessor, designer or installer. It does not identify any job as suitable for DIY, prescribe a product or replace a site inspection.
| Project | Record for your brief | Ask the provider to confirm | Costs easily left out |
|---|---|---|---|
| Grab bars | The task, resident’s preferences and known wall or enclosure type. Do not open walls to investigate. | Who checks personal suitability, positioning, the supporting structure and the specified mounting system? | Assessment, wall preparation, fixings, installation and making good. Read the mounting questions. |
| Entrance ramps | Rise, available space, units and door movement, only where you can observe safely. | What runs, landings, drainage, rails, edge protection and permission checks are included in the proposed route? | Ground preparation, platforms, delivery, installation and maintenance. Ramp length alone is not the scope. Compare geometry. |
| Doorway changes | The usable opening, approach, equipment model and relevant dimensions. | Are hinges, the frame or structural changes proposed? Who checks services, permissions and the complete route? | Survey, framing or other building work, moving services, finishes and disposal. A door price is not a widening quote. Compare the options. |
These are editorial scope questions informed by the sources below. NHS assessment guidance is for England; US ADA guidance describes covered facilities and is not a universal rule for private homes. Ask a local professional which requirements apply.
Turn the scope into a local budget
Ask both providers to price the same written brief in the same currency, with a quote date and validity period. Separate fixed amounts, provisional allowances, taxes, exclusions and contingency. Leave an unknown amount blank rather than treating it as zero. We have not invented a worldwide “DIY saving” or assumed that your labour removes installation risks.

Request the same breakdown
- Assessment, design and any required approvals.
- Exact products and model identifiers.
- Preparation, installation and making good.
- Electrical, plumbing or structural work where needed.
- Taxes, delivery and waste removal.
- Warranty, servicing and who handles faults.
Separate firm costs from allowances
Ask what is included, what is provisional and what may change after an inspection. Request an explanation of exclusions and how extra work will be agreed. Do not treat a generic online price as a quote for your property.
Check the evidence behind a recommendation
Ask who has assessed suitability, what measurements were used and whether the proposed model can be demonstrated. A lower price is not useful if the equipment cannot be safely used in the space.
Plan for disruption
Record the expected working period, access restrictions and alternative arrangements for essential rooms. Ask who is responsible for coordination and how the household will be informed about delays.
Check funding before starting
If you hope to use a grant or support programme, check its approval process before commissioning work. In the UK, GOV.UK warns that starting before council approval may prevent a Disabled Facilities Grant award. Other countries have different arrangements.
