You have three renovation quotations in front of you.

One is clearly cheaper.

One is in the middle.

One is considerably higher.

It is tempting to assume that you now have three prices for the same renovation.

Very often, you do not.

Two Hong Kong interior design companies can quote for the same apartment while including different demolition works, electrical points, bathroom specifications, cabinetry quantities, material allowances and project services.

That means the most important rule when comparing a renovation quote in Hong Kong is:

Compare scope first. Compare total price second.

Until the scope is reasonably aligned, the bottom-line totals are not truly comparable.

1. Start by checking whether all firms are pricing the same renovation

This sounds obvious, but it is one of the most common reasons quotations differ.

Perhaps one designer understood that you want to replace the entire kitchen, while another assumed some existing elements would remain.

Perhaps one quotation includes all bedroom wardrobes, while another only includes the master bedroom.

Perhaps one firm has included electrical rewiring, while another has priced only additional points.

Before asking why one company is more expensive, ask:

“Are they actually quoting for the same work?”

That question should come before any discussion about discount.

2. Do not begin with the final total

When homeowners receive quotations, the eye naturally goes straight to the last page.

HK$X versus HK$Y.

But the total is the result of everything above it.

Start from the major work categories instead.

Look at demolition, electrical works, plumbing, waterproofing, tiling, painting, ceilings, doors, flooring, kitchen, bathrooms and custom cabinetry where relevant.

Then compare the totals.

This reverses the usual process, but it produces a much more meaningful comparison.

3. Compare demolition scope carefully

“Demolition” can mean very different things.

One firm may include removing existing floor finishes, kitchen cabinets, bathroom finishes, doors and built-in furniture.

Another may include only the items specifically discussed during the first meeting.

If the apartment is a resale property, this can create a noticeable difference before new construction even begins.

So instead of comparing:

Demolition — Firm A vs Firm B

compare:

What exactly is being removed by each firm?

4. Check whether debris removal and site protection are included

Demolition creates another question:

What happens after everything is removed?

Depending on the project and quotation structure, disposal, site protection, transportation or related arrangements may be described separately.

Do not assume that every company bundles these items in the same way.

The important thing is not whether a particular line appears separately.

It is whether you understand the total scope you are buying.

5. Electrical quotations are especially difficult to compare by total price alone

Electrical work can appear simple on paper.

Then the number of sockets, switches, light points, dedicated appliance circuits and relocated points starts growing.

One quotation may give a broad lump sum.

Another may price by individual point or category.

Neither format is automatically better.

You need to understand the assumptions behind the number.

Ask whether the quotation covers the electrical changes required by your actual furniture, kitchen appliances, air-conditioning, lighting and layout.

A lower electrical allowance can become less attractive if many essential points later need to be added.

6. Check whether the electrical layout is already sufficiently defined

If your layout is still changing significantly, quotations may naturally differ.

One firm may have assumed a relatively simple arrangement.

Another may already be pricing based on a more developed design.

So if the electrical totals look very different, compare the underlying layout before concluding that one company charges more.

The more developed your floor plan, furniture plan and appliance list are, the easier it becomes to compare electrical quotations fairly.

7. Plumbing is another area where assumptions matter

Keeping existing bathroom and kitchen positions is different from substantially changing them.

Likewise, replacing finishes around existing plumbing is different from carrying out more extensive plumbing work.

If one designer is proposing a layout that requires more changes to services, its quotation may naturally be higher.

That does not automatically mean its unit pricing is higher.

It may simply be quoting for a more complex proposal.

Compare the design solution and the construction required to achieve it together.

8. Bathrooms need to be compared as complete packages

A bathroom quotation may involve demolition, waterproofing, plumbing, tiling, sanitary fittings, shower screens, cabinetry, mirrors, lighting and installation.

So a line that says:

Bathroom renovation

does not tell you enough by itself.

One firm may include the vanity and shower screen.

Another may expect the homeowner to purchase them separately.

One may include particular fittings.

Another may only include installation.

This can make two apparently similar bathroom prices surprisingly different.

9. Kitchen quotations can hide major differences in specification

Kitchen cabinetry is a particularly important comparison point.

Look at the approximate cabinet quantity, tall units, drawers, worktop, sink, hardware, finishes and appliance integration.

A visually similar kitchen can have very different internal specifications.

Also check what you are expected to purchase separately.

The quotation should allow you to understand which part of the kitchen budget belongs to the renovation company and which part remains with you.

10. Custom cabinetry is often where quotations drift furthest apart

Hong Kong homes frequently use built-in storage to make better use of limited space.

That means cabinetry can become a major component of the quotation.

But different designers may propose very different amounts.

One may design a simple wardrobe and TV cabinet.

Another may add full-height entrance storage, a dining cabinet, platform bed, window bench, study desk and display shelving.

The second quotation can be considerably higher even if its pricing is perfectly reasonable.

So before comparing “furniture cost”, compare:

How much furniture has actually been designed?

11. Compare cabinetry dimensions, not only the number of cabinets

“Three wardrobes” is not a meaningful comparison if one firm proposes three compact units and another proposes three full-height wall-to-wall units.

Where cabinetry forms a significant part of the quotation, look at the general dimensions and construction concept.

Also consider internal configuration.

Drawers, pull-out hardware, display sections, special finishes and integrated lighting may affect the cost.

The exterior rendering alone does not show the full specification.

12. Materials can make two similar designs very different in price

Two quotations may both include flooring, tiles, worktops and cabinet finishes.

But the material assumptions can be different.

One firm may have allowed for a basic specification.

Another may already be pricing the material range you selected during the design meeting.

If the material is not finalised, check whether the quotation uses an allowance or a particular specification.

Otherwise you may compare two totals that were built around completely different finish levels.

13. Watch for allowances and provisional items

Some items cannot be fully priced at the beginning.

That is not necessarily a problem.

What matters is recognising them.

A quotation may include a provisional allowance, an estimated amount or wording indicating that the final cost depends on selection or site conditions.

Treat these items differently from a fixed, clearly defined scope.

When comparing firms, ask:

Which parts of this total are confirmed, and which may still change?

This gives you a much better picture of the real budget uncertainty.

14. “TBC” is more important than it looks

Small phrases such as:

TBC / subject to site condition / to be confirmed / by actual quantity

deserve attention.

They do not automatically indicate a bad quotation.

Sometimes they are entirely appropriate because the final condition cannot yet be determined.

But if a large proportion of one quotation remains uncertain, its apparently low total should not be treated as fully fixed.

The amount of uncertainty matters almost as much as the current amount.

15. Compare exclusions before deciding which quote is cheaper

One of the best questions you can ask an interior designer is:

“What is not included?”

It often reveals more than another discussion about the included scope.

Depending on the project, exclusions may relate to appliances, air-conditioning, loose furniture, sanitary fittings, lighting, curtains or other owner-supplied items.

Different firms package projects differently.

You are not trying to force every quotation into an identical format.

You are trying to calculate what each option actually requires before you can move in.

16. Owner-supplied items can create a misleadingly low quotation

Imagine one company includes more fixtures and built-in items while another expects you to purchase them directly.

The second renovation contract may look cheaper.

But your total household expenditure may not be.

So maintain two mental numbers:

Renovation contract cost and total project cost.

They are related, but they are not always the same.

This is especially important when comparing quotations from firms with different service models.

17. Design fees should be compared by service, not label

Some Hong Kong interior design firms charge a separate design fee.

Others incorporate design services differently into the overall project.

A separate fee does not automatically make a company more expensive.

Ask what it covers.

Space planning? 3D renderings? Detailed drawings? Cabinetry design? Material selection? Site coordination?

Then compare the service, not simply whether the words “Design Fee” appear on the quotation.

18. Project management can also be packaged differently

Construction requires coordination between different trades.

For a relatively straightforward project, this may be simple.

For a full renovation with several bathrooms, extensive cabinetry, electrical changes and detailed finishes, coordination becomes more significant.

Some firms may reflect this service explicitly.

Others may incorporate it into the wider contract.

Again, the quotation structure is less important than understanding what the company will actually do during construction.

19. Look for duplicated or missing work between sections

Long quotations can sometimes be difficult to follow because similar work appears in different sections.

For example, part of a bathroom electrical scope may sit under electrical works while another related item appears under the bathroom section.

This is not automatically incorrect.

But when comparing quotations, make sure you are not accidentally counting something twice in one quote or assuming it is included in another when it is not.

Read by scope, not only by headings.

20. Do not compare unit rates without understanding the unit

A homeowner may notice:

“Firm A charges less per item than Firm B.”

But first check whether the item describes the same work.

A socket point, cabinet, door, tile installation or painting item can be measured and specified differently.

If the description is not equivalent, the unit rate comparison may be meaningless.

The cheapest individual line does not necessarily produce the cheapest or best overall project.

21. Very detailed quotations are useful, but detail alone is not quality

A quotation with many pages can give you more information.

But a long quotation is not automatically better.

Likewise, a shorter quotation is not automatically poor.

The real test is whether you can understand the major works, specifications, exclusions and pricing logic.

Ask yourself:

Can I explain what I am paying for?

If the answer is yes, the quotation is doing its job.

22. A low initial quote becomes risky when too much is left undefined

Low quotations are not inherently suspicious.

A genuinely efficient company may simply be more competitive.

The risk appears when the low total is combined with a vague scope, many unresolved allowances and unclear exclusions.

That combination makes it difficult to know whether the final project will remain at the initial amount.

Instead of asking:

“Why is this company so cheap?”

ask:

“What assumptions allow this company to quote at this level?”

That is much more useful.

23. A higher quotation may include more rather than cost more

This is the reverse of the same problem.

A higher total does not automatically mean the company’s rates are higher.

It may include a more complete renovation scope, more cabinetry, different materials or additional services.

Sometimes the right comparison is not:

HK$A versus HK$B

but:

HK$A for Scope A versus HK$B for Scope B.

Only after those scopes become more aligned should you judge price competitiveness.

24. Compare the proposed design as well as the quotation

This is especially important when choosing between interior design firms.

Different designers may solve your brief differently.

One design may retain more existing elements and cost less.

Another may significantly improve the layout but require more construction.

The higher quotation may therefore be purchasing a different outcome.

Before normalising every company to the lowest price, ask:

Which design do I actually prefer?

There is little value in choosing the cheapest quotation for a layout you do not want.

25. Ask each firm to clarify genuine gaps, not copy another quote line by line

Once you identify differences, it can be useful to go back to the firms.

But the goal should not be to force every quotation into identical wording.

Instead, clarify the important gaps.

For example:

Firm A includes this work. Does Firm B include it somewhere else?

One quotation includes this cabinet. Was it intentionally omitted from the other proposal?

One firm assumes existing flooring remains. Is that also the assumption in the other quotation?

This creates a fairer comparison without turning the process into a race to reproduce someone else’s document.

26. Do not negotiate price before you understand the scope

If you immediately ask every company:

“Can you reduce the price?”

you may receive a lower number without understanding what changed.

Sometimes a lower revised quotation is achieved by changing material, removing cabinetry or simplifying scope.

That may be completely sensible.

But you should know what you traded away.

The better sequence is:

Understand → align → prioritise → then negotiate.

27. Separate must-have works from adjustable design items

If every quotation exceeds the planned budget, do not randomly cut items.

Start by separating the project mentally into:

Essential work, high-priority design and optional elements.

For example, necessary underlying electrical, plumbing or waterproofing work may be harder to revisit after move-in.

A decorative feature wall or some loose furniture may be easier to simplify later.

The right cost reduction strategy depends on the project, but prioritisation is better than cutting whichever line appears expensive.

28. Variations matter as much as the initial quotation

A project can begin with a competitive quotation and still become expensive if the scope keeps changing during construction.

Before choosing a firm, ask how additional works or variations are handled.

Ideally, you should understand:

What changed, what it costs, whether it affects the programme and when approval is required.

You do not need to assume every variation is unreasonable.

Some are simply the result of homeowner-requested changes.

The important thing is transparency.

29. Check how old-property uncertainty is treated

Resale and older properties can contain conditions that are difficult to assess before demolition.

If a firm identifies genuine areas of uncertainty, this is not necessarily a negative sign.

What matters is how they explain them.

Which items are fixed?

Which depend on what is found after demolition?

How will additional work be discussed?

A quotation that acknowledges uncertainty clearly may sometimes be more useful than one that pretends everything is already known.

30. Compare payment schedules separately from quotation totals

Two firms can quote a similar total while asking for very different payment timing.

So before choosing, look at cash flow as well.

Understand when each payment is due and what stage it relates to.

The issue is not finding one universal “correct” payment schedule.

It is making sure you understand the financial commitment throughout the project.

This becomes particularly important for larger renovations.

31. Compare aftercare and defect handling

The quotation decision should not stop on the day construction finishes.

Ask how handover and outstanding items are handled.

Who records defects?

How are rectification items followed up?

What warranty or aftercare arrangement applies?

A slightly cheaper quotation may not be better value if the wider service is substantially different.

Likewise, a higher price does not guarantee stronger aftercare.

Ask before you decide.

32. Communication quality is part of the quotation decision

The quotation itself gives you useful information about how the firm works.

Do they answer scope questions clearly?

Can they explain why something costs more?

Do revised quotations track agreed changes?

Do they remember what was discussed?

A renovation involves many decisions after signing.

So the way a company handles quotation clarification can be an early indicator of how comfortable the working relationship may be.

33. Use a simple “scope alignment” method

You do not need complicated spreadsheet modelling.

Take your quotations and compare them room by room or trade by trade.

For example:

Demolition → Electrical → Plumbing → Bathrooms → Kitchen → Flooring → Painting → Doors → Custom cabinetry → Other items.

For each category, ask:

Same scope? Different scope? Missing? Unclear?

That alone can expose most of the major differences.

Once the important gaps are resolved, comparing totals becomes much easier.

34. When one quote is dramatically different, investigate before eliminating it

If one quotation is far above or below the others, do not immediately discard it.

First identify why.

Perhaps it includes substantially more cabinetry.

Perhaps one company has priced a more extensive electrical scope.

Perhaps one firm has excluded several items.

Perhaps the proposed design itself is different.

If you can explain the gap, you can decide whether it represents additional value or unnecessary scope.

If nobody can explain the gap, that is also useful information.

35. Do not choose by price alone — but do not ignore price either

“Never choose the cheapest quote” is too simplistic.

Sometimes the most competitive quotation genuinely is the best option.

Likewise, the most expensive quote does not automatically deliver the best design or workmanship.

Price should remain part of the decision.

It just should not be the only comparison.

A more balanced decision combines:

Scope clarity + design fit + quotation quality + communication + project management + price.

36. Your final quotation should make the contract easier to understand

Before signing, the final scope should be reasonably settled.

That means the quotation and contract should not contradict each other.

The version being signed should reflect the design and pricing you actually agreed.

This is particularly important if the quotation has gone through several revisions.

Make sure everyone is working from the same final version.

Once you reach this stage, the renovation contract becomes much easier to review because the commercial foundation has already been clarified.

What should you compare first?

If you only remember one framework, use this:

Scope → Specification → Exclusions → Uncertain items → Variations → Service → Total price.

Not:

Total price → discount → choose.

A quotation is not simply a number.

It is a description of the renovation you are agreeing to buy.

The more clearly you understand that description, the easier it becomes to recognise whether a lower price is genuinely better value or simply a different scope.

Frequently Asked Questions

How many renovation quotes should I compare?

There is no ideal fixed number. A smaller group of genuinely suitable firms with comparable scopes is usually more useful than collecting many quotations from companies offering very different services.

Should I choose the cheapest renovation quote?

Not automatically. First confirm that the major scope, specifications and exclusions are reasonably comparable. If they are, price becomes a much more meaningful deciding factor.

Why can two renovation quotations be so different?

Possible reasons include different design proposals, demolition scope, electrical and plumbing requirements, kitchen and bathroom specifications, cabinetry quantities, materials, exclusions and project services.

What is a provisional item in a renovation quotation?

It generally refers to an amount or scope that cannot yet be fully confirmed. The final price may depend on actual selection, quantity or site conditions, so it should be treated differently from a clearly fixed item.

Should every renovation quotation have the same format?

No. Companies structure quotations differently. The objective is not identical formatting but sufficient clarity to compare the underlying work.

Is a lump-sum quotation bad?

Not necessarily. The key question is whether you understand what the lump sum includes. A broad description becomes problematic when significant scope remains unclear.

Should I ask firms to match the lowest quote?

Only after understanding why the prices differ. A company may reduce the total by changing specifications or removing scope, so always check what changes with the revised price.

What should I check before signing after choosing a quotation?

Confirm the final quotation version, agreed scope, exclusions, uncertain items, payment arrangement, variations process, programme, handover and aftercare before signing the renovation agreement.

Can Designpedia help compare interior design companies?

Designpedia can help homeowners shortlist interior design and renovation firms based on project requirements. You should still compare each firm’s proposal, quotation and contract before making the final decision.
