Paying For New Windows In Exeter: Deposits, Finance And What Actually Protects Your Money

Windows are one of the largest single payments most Exeter households make outside a car or a kitchen, and almost nobody researches the payment terms with the same energy they spend choosing a frame colour. A full-house replacement in the city commonly runs somewhere between £6,000 and £12,000 depending on size and material, which sits squarely inside the £100 to £30,000 band where credit card protection applies. Deposits on made-to-measure work typically land between ten and twenty-five per cent. And a contract signed across your own kitchen table carries cancellation rights that a contract signed in a showroom does not. Those three facts decide how exposed you are if something goes wrong, and none of them appear in a brochure. Here is the money side of the job, set out properly.

What A Reasonable Deposit Looks Like, And What Doesn’t

There is a legitimate reason window installers ask for money up front. Frames are cut to your openings, in your chosen colour, with your chosen glass. If you walk away, nobody else can use them. A deposit covers the point where the order goes into manufacture and the installer’s money is committed.

That logic also tells you where the ceiling is. Ten to twenty-five per cent covers the manufacturing commitment comfortably. Half the contract value does not correspond to any cost the installer has incurred before your survey, so ask directly what the money is for. The answer will either be specific or it will be vague, and the vagueness is the information.

Better still is a contract that never puts a large sum at risk in one go. Staged payments tied to milestones are normal in the trade and easy to ask for: a deposit at order, a payment when the frames arrive on site and you can see them, and the balance after you have walked the job with the fitter and are satisfied. Protect that final stage above all. It is the only leverage you have left once the work is done. When we price a window installation in Exeter we set those stages out on the quote itself rather than leaving them to a conversation.

The bits that should make you pause

Requests for cash. Requests to pay a person rather than a registered company. A deposit demanded before anybody has measured anything. A price that only holds if you pay today. None of them proves dishonesty on its own. Each one quietly removes a protection you would otherwise have had, which is the thing they have in common.

Why The Card You Pay With Changes Your Rights

The most valuable thing you can do with a window deposit costs nothing and takes no longer than paying any other way: put it on a credit card.

Section 75 of the Consumer Credit Act 1974 makes your card provider equally answerable with the installer where the cash price of the goods or services is above £100 and no higher than £30,000. Most whole-house window jobs in Exeter fall inside that band. The detail people miss is that partial payment is enough. Put a £900 deposit on a credit card against a £7,000 contract and the entire £7,000 contract comes within reach of a claim, not just the £900. You can pay the rest by bank transfer and lose nothing.

A debit card is a weaker position. You get chargeback, which is a rule of the card schemes rather than a statutory right, and it is generally subject to a window of around 120 days from the transaction or the date the work was due. Chargeback is genuinely useful and you should pursue it, but it is discretionary, it is capped at what you actually paid, and it has no equivalent of the “whole contract” reach that Section 75 gives you. Bank transfer offers neither.

If a company adds a surcharge for credit cards, note that consumer card surcharging has been banned in the UK since January 2018. A quiet two per cent “card fee” on a glazing invoice is not something you have to accept.

Insurance-Backed Guarantees: Ask Who Underwrites It

An insurance-backed guarantee, or IBG, exists for exactly one situation: the installer has stopped trading, so the guarantee it gave you has nobody left to honour it. While the company is still in business, the IBG is dormant and your route is against the installer. We covered how that interacts with product and workmanship cover in our guide to what a double glazing guarantee actually covers, and the two sit side by side.

What that guide does not test is the policy itself, which is where the money question sits. An IBG is only as good as the entity standing behind it. Some are written by established insurers. Others are arranged through intermediaries, and a small number are little more than a promise on headed paper from a company with no insurance permissions at all. The distinction is invisible on the sales pack and easy to check afterwards.

So ask for the underwriter’s name, in writing, before you sign. Then look that firm up on the FCA’s Financial Services Register, which lists every firm authorised to carry on insurance business in the UK. Two minutes of searching separates a real policy from a decorative one.

The deposit cover hiding inside the policy

Many IBG products include deposit protection as well as defect cover, typically limited to around a quarter of the contract value or in the region of £10,000, whichever is lower. That is genuinely useful, and it is almost never mentioned in the sales conversation. Read the schedule, note the cap, and keep the certificate with the rest of your paperwork.

What FENSA And CERTASS Registration Does And Doesn’t Promise

Archive files representing building regulations registration records for replacement windows in Exeter

FENSA and CERTASS are both government-authorised competent person schemes, and both let a registered installer self-certify replacement glazing against the building regulations instead of booking a council inspection. CERTASS has held that authorisation since 2006. Either scheme produces the compliance certificate your solicitor will ask for when you sell, and our guide to FENSA certificates in Exeter covers what to do when yours has gone missing.

Here is the part that gets misread. Registration is a building regulations mechanism. It confirms the installation was notified and met the technical standards, and scheme membership carries obligations around deposits, guarantees and dispute resolution that a registered firm is expected to meet. What it does not do is vet your individual price, supervise your particular job day to day, or promise that the company will still exist in three years.

So treat a scheme logo as a starting filter rather than a conclusion. Confirm the registration number is current on the scheme’s own database rather than trusting a logo on a van. Ask which dispute resolution service the firm belongs to, because that is the route you will use if a disagreement turns formal. And keep the compliance certificate separate in your mind from the guarantee and the insurance policy. They are three different documents doing three different jobs, and plenty of quotes blur them deliberately.

Finance Agreements And What “Interest Free” Actually Costs

Spreading the cost over two or three years is a perfectly sensible way to buy windows, and finance is regulated: a firm arranging credit has to be authorised or appointed by the FCA, and it must quote a representative APR rather than just a monthly figure. Home improvement finance commonly advertises somewhere in the region of 9.9 to 14.9 per cent APR on interest-bearing plans, so on a £8,000 job over five years the interest alone can add well over £2,000.

The offer that needs more thought is the 0 per cent deal. Interest-free credit is not free to provide. The lender charges the installer a subsidy for every agreement written, and that subsidy has to come from somewhere, which in practice means the headline price. The test is simple and it takes one question: what is your price if I pay in full by bank transfer or card instead? If the number drops, you now know what the interest-free option costs, and you can compare it against the cost of borrowing the same amount elsewhere.

Two further points people trip over. A deposit paid within a finance agreement is often treated differently from a cash deposit for protection purposes, so ask specifically how yours is held. And a regulated credit agreement carries its own cancellation rights, separate from the cancellation rights on the installation contract itself, which can produce the awkward situation of having cancelled one but not the other.

Fourteen Days To Change Your Mind, And The Clause That Removes Them

A contract signed in your own home is an off-premises contract, and it normally comes with a fourteen-day cancellation period that the trader has to tell you about in writing before you sign. That is a real protection and it exists precisely because kitchen-table selling puts people under pressure that a showroom does not.

There are two important qualifications. The first is that goods made to your specification can fall outside the cancellation right. Windows are made to measure, so installers who intend to rely on that exclusion must make it clear at the point of sale. If nobody told you, the exclusion is harder for them to lean on.

The second catches more people. If you sign the form asking for work to begin during the fourteen days - the one that gets slid across as “this just lets us get your survey booked in” - you keep the right to cancel, but the Consumer Contracts Regulations require you to pay a proportionate amount for what has already been supplied. Cancel on day twelve after a survey and a manufacturing order, and you will be settling up for both. The flip side cuts your way: if the trader failed to give you the required cancellation information, you may owe nothing at all, and the cancellation period itself can extend to a year and fourteen days.

You do not have to refuse. Plenty of people want the survey booked and the order placed quickly, and that is a reasonable choice. Just sign that box knowing it turns fourteen unconditional days into fourteen conditional ones.

The Manager’s Price, The Today-Only Discount, And How To Answer

Doorstep glazing sales has a long and well-documented history of pressure tactics, and the scripts have barely changed in thirty years. The price starts high. A phone call is made to a manager. A discount appears that expires when the salesperson leaves your hallway. Sometimes there is a “show home” angle, where your house is apparently going to be photographed for marketing in exchange for a reduction.

You do not need to argue with any of it. One sentence handles the lot: “I don’t sign anything on the first visit. Leave the quote and I’ll come back to you.” Say it early, before the discount appears, and the evening gets much shorter. A genuine price survives a week. Every firm quoting honestly in Exeter knows its own costs and will hold a figure long enough for you to compare it. A price that evaporates at the front door was never the real price.

Exeter gives you a practical reason to take that week anyway. The city’s housing runs from Georgian and Victorian stock in and around the conservation areas to postwar and modern estates out at Pinhoe, Alphington and Countess Wear, and quoting accurately for a period property with irregular openings, deep reveals or heritage constraints takes more than a tape measure and twenty minutes. Two quotes on the same house can differ by thousands because one has allowed for making good around old lintels and the other has not. That is not a comparison to rush.

If it has already gone wrong

Put the complaint in writing to the company first, dated, and keep a copy. If that goes nowhere, use the installer’s dispute resolution or ombudsman scheme. Where you suspect a trader is acting unfairly rather than merely badly, report it through the Citizens Advice consumer helpline on 0808 223 1133, which is the route that passes cases to Trading Standards - for this part of Devon, the Devon, Somerset and Torbay Trading Standards Service. You cannot refer a case to Trading Standards directly yourself, which surprises most people who try.

Frequently Asked Questions

How much deposit should I pay for new windows in Exeter?

Somewhere between ten and twenty-five per cent of the contract value is the usual range for made-to-measure windows, because frames are cut to your openings and cannot be sold to anyone else. Most reputable installers sit nearer the bottom of that band than the top. What matters as much as the percentage is what happens afterwards: a contract that splits the balance into a payment on delivery and a final payment after you have inspected the finished work protects you far better than one lump sum on day one. Treat a request for fifty per cent or more before a survey has even been carried out as a reason to stop and get two more quotes. Cash-only requests, or requests to pay a named individual rather than the company, should end the conversation entirely.

Does paying a window deposit by credit card protect me?

Yes, and it is the single cheapest piece of protection available. Under Section 75 of the Consumer Credit Act 1974, where the cash price of what you are buying is more than £100 and no more than £30,000, your credit card provider carries the same liability as the installer for breach of contract or misrepresentation. The useful part is that you do not have to put the whole job on the card. Paying the deposit alone on a credit card brings the full contract within that protection, so you can settle the balance by transfer and still have a claim if the company folds before fitting. Clear the card straight away and it costs you nothing. A debit card gives you chargeback instead, which is a card scheme rule rather than a legal right and normally has to be started within 120 days.

Is an insurance-backed guarantee worth anything if my installer stops trading?

Only if a real, regulated insurer stands behind it. An insurance-backed guarantee is a policy that pays for defects your installer would have put right, in the event that the installer no longer exists to put them right. That makes the identity of the underwriter the whole question. Ask for the name of the insurer, not the name of the guarantee, and check that firm appears on the FCA's Financial Services Register. Some policies also carry deposit cover, commonly capped at around a quarter of the contract value or roughly £10,000, whichever is lower. The policy has to be registered in your name after the job finishes, so chase the certificate rather than assuming the salesperson arranged it.

Can I cancel a window contract I signed at home in Exeter?

Usually, but the small print decides it. A contract signed in your own home is an off-premises contract, and those normally carry a fourteen-day cancellation period that the trader has to tell you about in writing. Two things cut across it. Goods made to your specification can be excluded, which is why installers who want to rely on that exclusion have to make the made-to-measure nature of the order clear at the point of sale. And if you signed a form asking for work to begin inside those fourteen days, you can still cancel, but you owe a proportionate amount for whatever has already been supplied. If the trader never gave you the cancellation information in writing at all, the period can stretch to a year and fourteen days, and you may owe nothing for services supplied early.
