Owners: Improve Or Move? How To Decide Now

Every homeowner arrives at this question eventually, usually standing in a kitchen that has stopped working for the family in it.

Do we spend the money here, or do we spend it moving?

There is no universal answer, but there is a much better way to reach yours than by feel. It comes down to five questions, and most people only ask the first one.

Question one: is it the house, or is it the location?

Start here, because it settles a surprising number of cases on its own.

If the house is too small but you love the street, the school, the neighbours and the walk to the station, improving is worth serious thought. Those are the things money cannot easily buy back.

If what you actually want is a different area, a shorter commute or a different kind of neighbourhood, no extension will deliver it. People spend a great deal of money extending their way around a problem that was never the building.

Be honest with yourself about which it is. The answer is usually available if you sit with the question for a week.

Question two: what does moving actually cost?

Moving costs are widely underestimated because they are spread across several invoices.

Stamp duty on the property you are buying, which on a larger home is often the biggest single figure.
Estate agency fees on the sale, plus legal fees on both the sale and the purchase.
Survey, mortgage arrangement and any early repayment charge on your existing mortgage.
Removals, storage, and the immediate spending that always follows a move. Blinds, carpets, decorating, the thing that turns out not to fit.
The cost of the process itself. Months of viewings, uncertainty and a chain you do not control.

None of that means moving is wrong. It means the comparison has to be against the full figure, not against the price difference between the two houses.

Question three: what does improving actually cost?

Also underestimated, and for a different reason. People price the build and forget everything around it.

Design and professional fees. Architect or designer, structural engineer, planning application, building regulations.
The build itself, and a genuine contingency on top. Ask anyone who has done it, and they will tell you the contingency was not optional.
VAT, where it applies.
The finishing that never appears in the quote. Decorating, flooring, the kitchen or bathroom that now has to match, the landscaping where the garden was dug up.
The disruption. Weeks or months of living in a building site, possibly without a kitchen, possibly with small children.

That last one is a real cost even though it never appears on paper. Some households take it in their stride. Others find it genuinely miserable, and it is worth knowing which you are before you start.

Question four: What is the ceiling price on your street?

This is the question almost nobody asks, and it is the one that costs people the most money.

Every street has a level beyond which buyers stop paying, no matter what you have done to the house. Spend £80,000 extending a property in a road where nothing has ever sold above a certain figure, and a good deal of that money does not come back.

That does not make it a bad decision. Improving your home so it suits your family for the next fifteen years can be excellent value even if it never shows up in the resale price. But you should know which one you are doing. Spending for love is fine. Spending for love while believing you are investing is how people get a nasty surprise later.

This is the single most useful thing to ask a local agent, and it takes one phone call.

Question five: how long are you actually staying?

The maths changes completely depending on the answer.

If you plan to be there ten or fifteen years, an extension that suits you and does not fully return its cost is a reasonable trade. You are buying fifteen years of a better life, and the cost per year is modest.

If you might move in three, the numbers get harsh. You would carry the full cost and the disruption, recover only part of it, and then pay the moving costs anyway.

How do you actually settle it?

Get two real numbers before you decide anything, and get them in this order.

A proper builder’s quote for the work you actually want. Not a rough figure over the phone, and ideally more than one.
A valuation of your home as it is now, and an honest view of what it would be worth with the work done. Any decent local agent will give you both, and should tell you plainly if the second figure is not much higher than the first.

Put those beside the total cost of moving, including stamp duty, and the answer is usually obvious within about ten minutes. It is the guessing that makes this decision feel impossible.

Want both numbers before you decide?

We are very happy to tell you what your home is worth now, what it might be worth improved, and where the ceiling on your street actually sits, with no expectation that you are going to sell. Plenty of the people we have this conversation with end up extending, and we would far rather they decided with real figures.

Frequently asked questions

Is it cheaper to extend or to move?

It depends on the cost of the work, the stamp duty and fees on a move, and the ceiling price on your street. The only reliable way to know is to get a builder’s quote and a valuation of the improved property, then compare both against the full cost of moving rather than the price gap between houses.

What is a ceiling price?

The level beyond which buyers on a particular street stop paying, however much has been spent on the house. Improving past it means much of the money does not come back on resale, which can still be the right choice if you are staying long enough to enjoy it.

What costs do people forget when moving?

Stamp duty on the purchase, agency and legal fees on both sides, survey and mortgage costs, any early repayment charge, removals, and the immediate spending on the new home such as carpets, blinds and decorating.

What costs do people forget when extending?

Design and professional fees, planning and building regulations, contingency, VAT where applicable, and the finishing work such as decorating, flooring and matching the rest of the house. Plus the disruption of living through it.

Does an extension always add value?

No. It usually adds some value, but not always as much as it cost, and rarely beyond the ceiling price for the street. Ask a local agent what the realistic improved value would be before you commit.
