BuyBack HTB
If you have made the decision to repay your Help to Buy (HTB) equity loan—whether through remortgaging, with savings, or via the sale of your property—you will quickly encounter an inescapable procedural hurdle: the RICS valuation.
Unlike a standard bank loan where you owe a fixed cash sum, your Help to Buy debt is defined as a percentage of your home's current market value. Because this percentage fluctuates with every movement in the property market, the government cannot accept your own estimate, your estate agent's informal guess, or an automated tool's data-driven approximation.
To establish a legally binding repayment figure, Homes England (via the scheme administrator, Lenvi) requires a formal written valuation from a qualified surveyor who is registered with the Royal Institution of Chartered Surveyors—a RICS valuation.
This is not optional. Without a valid, in-date RICS report, the entire redemption process cannot proceed.
RICS valuations for Help to Buy purposes typically cost between £300 and £600, depending on the size of your property and where you are in the country. London and the South East tend to attract higher fees. Some surveying firms charge a flat fee; others price by property type or square footage.
It is worth shopping around, but choose on reputation and HTB experience rather than purely on price. A surveyor familiar with Help to Buy redemptions will understand the specific report format and comparables required by Lenvi, reducing the risk of the report being rejected.
Here is the uncomfortable truth: when selling your home, a high valuation is good news. When repaying a Help to Buy loan, a high valuation is expensive news.
If you have a 20% equity loan on a property now valued at £300,000, you owe the government £60,000. But if the same surveyor, on the same day, had valued the property at £320,000 instead, you would owe £64,000. That £20,000 difference in valuation results in a £4,000 increase in your personal debt to the government—on a judgement call made in under two hours.
Because property valuation is part science and part subjective expertise, two accredited RICS surveyors could legitimately reach different conclusions. This makes it important for you to understand the process and to prepare your home for the visit strategically.
If you are selling your home rather than remortgaging, Lenvi will calculate your repayment based on the higher of the RICS valuation or the actual agreed sale price. This prevents undervaluing in a private sale to reduce the government's cut.
The simplest way to find RICS-registered surveyors in your area is via the official RICS "Find a Surveyor" tool at rics.org. When making contact, always confirm the following before booking:
The surveyor you choose must have no connection to the estate agent who is selling your home, if applicable. Any conflict of interest will result in an automatic rejection by Lenvi.
Once your surveyor generates the valuation report, a strict 90-day countdown begins. The HTB scheme administrator, Lenvi, will only accept a valuation report that was generated within the last three months. If your report expires before completion, the process stops.
The danger is that the overall remortgage and redemption process—from submitting a mortgage application to completion day—regularly takes two to three months in itself. Add in any delays from Lenvi, solicitor bottlenecks, or lender queues, and the risk of the valuation expiring mid-process becomes very real.
The optimal approach is to commission the RICS valuation only after you have all of the following in place:
Ordering the valuation at this stage ensures the 90-day window is still live on completion day, with several weeks of safety margin remaining.
If you miscalculate and the three months pass, all is not lost—but it will cost you extra time and money. You have two options:
In almost every other context, homeowners try to maximise their property's perceived value before a surveyor visits. Help to Buy is the exception. Here, you want the most accurate, arguably most conservative, defensible valuation. Here is how to approach the visit.
Before the surveyor arrives, spend time on the Land Registry sold price search and on property portals filtering for Sold Prices (not listing prices) for homes identical to yours—same property type, same number of bedrooms, same estate if possible—within the last six months. Print or note the figures.
This serves two purposes. First, you will know what a fair valuation should look like before you receive it. Second, if you believe the surveyor's figure is too high, you will already have evidence to challenge it.
Do not attempt to hide defects. Point them out proactively during the inspection:
None of this constitutes deception; it is simply a fair representation of the home's real condition. Surveyors will factor genuine defects into their report.
When you originally purchased using Help to Buy, you bought a brand-new property. New builds carry an inherent premium—often 5% to 15% above the equivalent second-hand market value—simply because of their novelty. The moment you move in and the property is no longer "new," this premium evaporates.
As a result, many Help to Buy homeowners are surprised to find that their property's value barely moved in the first two or three years, even when the broader market was rising. The new build premium unwound as the market caught up to the property's underlying value.
When speaking to your RICS surveyor, it is entirely reasonable to politely raise this point and note that your home has now fully made the transition to the second-hand market. A good surveyor will already account for this, but it is worth raising.
If you have made any structural improvements—a kitchen extension, a loft conversion, a new bathroom suite—note that Homes England claims a proportionate share of any added value from those improvements too, because they still own a percentage of the overall property.
If you made improvements without getting written permission from Homes England (which is required under the HTB terms), you may face complications. However, if you did obtain permission, the surveyor will likely recognise the value added. You do not need to downplay genuine improvements; just understand that a higher final value means a higher government payout, which reinforces the case for buying out sooner rather than later.
If the surveyor's draft report arrives and the figure feels inflated, you can challenge it. However, the bar is high. You cannot simply say "I think it is too high." You must provide concrete, verifiable evidence that the surveyor's comparable properties were not truly comparable.
The evidence surveyors will most readily accept is a set of three or more recent Land Registry confirmed sold prices for properties that are genuinely equivalent (same style, same condition, same street or estate) that collectively support a lower figure than the surveyor's.
Send this evidence to the surveyor before they finalise the report. Most surveyors will re-examine their comparable evidence if presented with a strong counterfactual. If you have already received their final report and believe it is materially wrong, you can formally dispute it through the RICS complaints procedure—but this takes additional time and is best avoided by engaging early in the draft stage.
Once Lenvi reviews and accepts your RICS report, they will issue an Authority to Proceed (ATP). This document states the exact cash figure you must pay to redeem the equity loan in full (e.g., 20% × surveyor's value).
Your solicitor uses this figure to prepare the completion finances. From here, the process moves to its final stage: completion day, when your solicitor simultaneously redeems your existing mortgage, pays off the government, and your new mortgage begins.
Once the funds transfer, Lenvi notifies the Land Registry, and the government's beneficial interest—the charge that has sat on your property's title deeds since the day you moved in—is formally removed. For the first time since you bought your home, you own all of it.
The RICS valuation and the broader redemption process only make sense if you have first confirmed that the buyout is financially worth it for your specific situation. Before you spend money on a surveyor, run your numbers through our BuyBack HTB Calculator.
By entering your property value, mortgage balance, and current inflation assumptions, the tool will project the total long-term cost of keeping the equity loan versus buying it out today—and calculate the exact income you would need to qualify. Go in with the data. Make the decision with confidence.
