Red Book reports for staircasing, assignment, remortgage and lease extension.
Regulated
Horsham shared-ownership paperwork is rarely simple. Our RICS-registered valuers produce a Red Book valuation that housing associations accept when they ask for a formal report, and our team turns reports around fast. Fees are fixed, starting from £350 for homes under £300,000, £425 from £300,000 to £500,000, £495 from £500,000 to £750,000, and £595 above £750,000. The report is issued within 5 working days of inspection, which helps when your staircasing, sale, or remortgage window is already moving.
Across Horsham, from the town centre conservation area around Market Square and The Causeway to newer homes in RH12 4SE, the market covers a wide spread of prices. homedata.co.uk records show an average sold price of £525,845, while flats average £252,536, which is often the bracket that shared ownership starts to make practical sense in. Active new-build activity in the RH12 4SE area includes Highwood Green, Broadacres, The Maples, and Orchard Gate, so there is plenty of current market evidence for a Red Book valuer to weigh up.

Using listing data from home.co.uk and property data from homedata.co.uk
A shared-ownership valuation is usually needed the moment you change the ownership split. Staircasing is the obvious one, because the price of the extra share is based on the valuer's open market figure, not on what you think the home feels worth after a tidy-up on a street off the A24. Final staircasing uses the same Red Book route, only this time the last share is bought and the property becomes fully owned, with no rent due on the unsold part.
Selling your share is different, but the paperwork is just as strict. In an assignment, your housing association normally has a nomination period of 4 to 8 weeks to find a buyer before you can market the home more openly, which can matter if you are leaving a flat near Market Square or a house in RH12 with a tight moving date. Re-mortgaging and lease extension work also tend to ask for the same kind of report, because the figure has to stand up to lender scrutiny and association checks, not just your own estimate.

Staircasing is a maths problem first and a property transaction second. The valuer sets the open market value, then your share is priced from that figure, so a 10% step on a Horsham flat valued at £252,536 comes to £25,254, while a 25% share would be £63,134. That is why a Red Book report matters so much in shared ownership, especially on homes in RH12 4SE where newer estates and older stock can sit only a few roads apart but value very differently.
The same logic applies on a larger home. If a terraced property in Horsham is valued at £391,373, a 10% staircasing tranche is £39,137.30 before any lease or legal fees are added, and that figure can feel very different from the flat example at the top end of the town's shared-ownership range. We use local sold evidence, not guesswork, so a home near the town centre conservation area will be compared with similar homes, while a post-1980 flat on the edge of town will be judged against more relevant transactions.
Let us know if you are staircasing in Horsham town centre, selling by assignment in RH12, or remortgaging a flat near Broadbridge Heath. We will confirm the right instruction and the fee band before booking anything.
Shared ownership often involves more admin than a normal sale, so we work around your tenancy, your agent, and any estate rules. Homes near The Causeway or newer developments in RH12 4SE can have different access arrangements, and we deal with that early.
Our RICS-registered valuer looks at the building, the layout, the condition, and the comparables that matter in Horsham. On homes built on Weald Clay or close to flood-sensitive spots such as the River Arun and Boldings Brook, that site knowledge matters.
Your valuation is written up in line with RICS Valuation Global Standards and issued within 5 working days of inspection. The report sets out the open market value and the evidence used, so your housing association can process it without delay.
Once the report arrives, you can send it with your staircasing, sale, or remortgage papers. The 3-month validity clock starts from the inspection date, so timing matters if your application is tied to a mortgage offer or a sale deadline.
Housing associations in Horsham and the wider RH12 area usually enforce valuation validity strictly. If your application window is still open, time the instruction so the report does not expire before the paperwork lands on the right desk. A Red Book that is only a few days too old can slow everything down.
Horsham is not a one-size-fits-all market. The housing stock is split between detached homes at 33.6%, semi-detached at 30.5%, terraced at 18.2%, and flats or maisonettes at 17.1%, so shared ownership tends to sit where the flats and smaller houses are. That matters because a flat averaging £252,536 is a very different proposition from a detached home averaging £822,544, and the gap changes how staircasing feels in practice.
New-build activity adds another layer. home.co.uk lists active homes at Highwood Green from £499,995 to £799,995, Broadacres from £499,995 to £799,995, The Maples from £374,995 to £649,995, and Orchard Gate from £549,950 to £999,950, all in RH12 4SE. Those figures sit above the level where many shared-ownership buyers start, which is why the scheme often makes most sense at the flatter end of the market or on smaller terraces close to the town edge.
Condition also matters in Horsham because the local build story is varied. The town centre conservation area, the listed buildings around Market Square and The Causeway, and the common use of red brick and tile hanging all affect comparables, while Weald Clay brings shrink-swell movement, subsidence risk, and occasional heave. Add river and surface water flood risk from the River Arun, the River Adur, and Boldings Brook, and a valuer has to weigh evidence carefully rather than rely on a simple postcode average.
Older homes can need more scrutiny than the headline prices suggest. Pre-1919 properties make up 13.5% of the stock, and those homes can show cracking, damp penetration, roof spread, or timber decay, while 1945 to 1980 stock at 31.0% can bring cavity wall or wall tie issues. That is one reason a Red Book valuation in Horsham should be built from comparable evidence and a proper inspection, not from a quick online estimate.
A Red Book valuation is not a rough guess. It is the valuer's opinion of open market value, reached from comparable sold evidence, property condition, location, and local market movement, which in Horsham includes recent sales in RH12, the town centre, and newer schemes off the A264. If a flat near Market Square has a different layout, parking arrangement, or lease position from a similar unit in Broadbridge Heath, that difference shows up in the figure.
You can challenge a valuation, but only in a limited way. If a factual point was missed, or the condition has changed since inspection because of damp, movement, or a new defect on a Weald Clay plot, you can ask for a re-inspection, yet you usually cannot simply argue the price down because you hoped for a lower number. That is why the inspection stage matters in Horsham, where red brick terraces, post-1980 flats, and listed homes around The Causeway rarely compare cleanly with one another.
The valuation is valid for 3 months from the inspection date. In Horsham, housing associations are usually strict about that, so a report issued for a home in RH12 or near Market Square should be timed to match your application window, not booked too early.
Staircasing, final staircasing, selling your share by assignment, re-mortgaging, and lease extension work can all trigger the need for a Red Book report. In practice, the trigger is the moment the share price or the legal paperwork needs a formal open market value, whether the home is a flat in RH12 4SE or a terrace near the town centre.
Usually the leaseholder pays. If you are staircasing a flat at The Maples or remortgaging a home in Broadbridge Heath, the cost normally sits with you, although in a sale the expense is often met from the sale proceeds rather than paid separately by the buyer.
We inspect first, then the Red Book report is issued within 5 working days of inspection. That speed helps in Horsham, where mortgage offers, association forms, and nomination periods can all be moving at once.
Not in the usual sense. A Red Book valuation has to follow RICS Valuation Global Standards and comparable evidence from Horsham sales, so the figure stands unless a factual issue was missed or the property has changed since inspection, such as new cracking linked to Weald Clay or fresh water ingress after heavy rain.
Most rejections happen because the report is not Red Book, the valuer is not RICS-registered, or the document has gone out of date. If that happens with a home in RH12 or near the town centre, send the compliant report they asked for and check exactly which requirement was not met before you proceed again.
On New Model shared ownership, usually yes, 1% a year on schemes introduced after 2021. Older Horsham schemes still tend to work in 10% minimums, so a buyer in a flat near Market Square may have very different staircasing terms from someone on a newer estate in RH12 4SE.
Final staircasing buys the last share, so you own 100% outright. After that, the rent on the unsold share stops, which is a major shift for leaseholders in Horsham who have been paying rent alongside their mortgage for years.
Yes, if the condition changes or new evidence appears. A re-inspection can be sensible after a period of heavy rain in Horsham, especially on homes exposed to surface water or on plots where tree roots and Weald Clay have already raised concerns.
