Bob's Mechanical Repairs is a physical workshop in Birnam, Perthshire. We do not have premises in Northampton. This page is an independent garage guide written by Bob — no Northampton garage is represented here unless a named, verified partner garage is listed on this page. Bob can give written advice on your vehicle by email; the network is still looking for one verified partner garage in Northampton.
No partner garage in Northampton yet — here's what you can still do
Bob runs a workshop in Birnam, Perthshire and is signing up independent garages elsewhere in the UK, one per town, each reviewed before listing. There is no verified Northampton garage yet, which is why you will not find a local booking button on this page.
Until a Northampton garage joins, the Ask a Mechanic service is still open to you. Send the symptoms, the fault code or the estimate you have been quoted for MOT testing and Bob replies in writing with what he would do and what it should cost.

How this guide works
This page is a reference guide, not a booking page for a workshop in Northampton. It sets out the typical scope of MOT testing, the price range drivers usually see, and the questions worth asking so you can compare quotes properly.
Availability and the final price always depend on the garage you choose. Anything quoted here is a guide figure taken from typical UK independent-garage pricing, not an offer.
MOT classes explained for Northampton drivers
MOT testing in Northampton covers Class 4 (cars and light vans up to 3,000kg, DVSA maximum £54.85), Class 5 (minibuses and larger passenger vehicles, 13+ seats) and Class 7 (commercial vans between 3,000kg and 3,500kg, DVSA maximum £58.60). Most drivers need a Class 4 test; van owners should check the plated weight before booking, because a Class 7 vehicle cannot legally be tested on a Class 4 bay.
The published DVSA maximum covers the standard MOT test, including the emissions check. If a garage quotes anything additional, ask for the optional or extra work to be set out in writing. A retest may be free where the vehicle is left for repair and retested within 10 working days, subject to the retest conditions published on GOV.UK. If you are not sure which class your vehicle falls into, check the V5C for the revenue weight rather than guessing from the body shape.
How to choose a garage in Northampton
Check the garage is on the DVSA register if you need an MOT, ask whether the technicians are IMI or City & Guilds qualified, and look for recent reviews that mention the same kind of work you need doing.
Ask for a written quote before any work starts, ask whether old parts can be shown to you afterwards, and confirm that servicing will be recorded to the manufacturer schedule so a warranty stays intact. A garage that will not put a price in writing is not worth the risk.
Questions worth asking before you book
Is the quoted price inclusive of parts, labour and VAT? Will diagnostic time be credited against the repair if you go ahead? What happens if extra faults are found once the car is stripped? How long will the car be off the road?
On older vehicles it is also worth asking whether the garage will supply a photo or video of anything they say needs replacing. Some garages can provide this — it is worth asking.
Driving conditions around Northamptonshire
Local roads shape what wears out first. Where you have a lot of stop-start traffic, brakes and clutches go early; on rough rural surfaces it is suspension and tyres; near the coast it is corrosion. Mention the kind of driving you do when you get a quote — it changes what a garage should be checking.
Bob's advice for Northampton drivers — from the Birnam workshop
Robert McMahon — Bob to customers — has been a mechanic for 32 years and runs Bob's Mechanical Repairs in Birnam, Perthshire. He cannot work on your car in Northampton, and this page never pretends otherwise. What follows is the advice he gives across the counter every week about MOT testing: what the job involves, what it should cost, and where drivers get caught out. It applies the same whether the car is on his ramp or on someone else's.
Diesel problems worth knowing about before you book in Northampton
Most blocked DPF jobs Bob sees started as short journeys — the filter never gets hot enough to burn off soot. A forced regeneration is usually £90–£180; a replacement filter is £600–£1,400. Before agreeing to a new one, ask the garage to show you the soot and ash readings from the live data, because ash is the figure that decides whether the filter is genuinely finished.
The same applies to EGR valves and swirl flaps. Cleaning is often £120–£250 against £400+ for replacement, and a decent garage in Northampton will tell you honestly which one your car needs rather than defaulting to the bigger bill. Get the fault codes written on the invoice either way — it matters if the problem comes back.
Getting a second opinion without wasting anyone's time
Before you pay for a second diagnosis, gather what you already have: the fault codes, the invoice or estimate, the mileage, the symptoms and when they happen. Photographs of the failed part or the advisory sheet help more than any description.
With that in hand a second garage in Northampton can usually tell you in minutes whether the first quote is sensible. Bob does the same thing in writing through Ask a Mechanic for drivers anywhere in the UK — you send the quote and the codes, he tells you what he would do and what it ought to cost.
Keeping an older car alive without throwing money at it
On a car worth £1,500, the rule Bob uses is simple: spend on anything that affects stopping, steering or safety, and think hard about everything else. Brakes, tyres, suspension and structural corrosion are worth the money. Cosmetic trim and convenience electrics usually are not.
Get an honest pre-MOT look each year rather than gambling on the test. Knowing about a corroded brake pipe in advance means budgeting for it, not being held to ransom with the car already on the ramp and a certificate expiring.
The short version
Bob writes this from the ramp in Birnam, not from an office. If your MOT testing quote in Northampton does not match what is described here, ask the garage why — and ask Bob for a written second opinion if the answer is vague.

Garage owners in Northampton
How can a garage in Northampton get more customers from Google?
Search results for MOT testing in Northampton are dominated by chains and booking portals with big content budgets, not by better mechanics. This page already sits in those results. A single Northampton garage can apply to be named on it, putting a local workshop in front of drivers who are already searching. Nothing is listed until the application has been reviewed.
Can a Northampton garage be named on this guide?
Yes, and only one workshop is listed per town. You apply through the partnership form, Bob reads the application himself, and if it is approved and activated your name, details and website go on the page. Eligible enquiries may then be offered under the agreed terms. There is no lock-in.
What does the Northampton garage listing include?
Beyond the listing itself you get the BMR garage management system used in Bob's own workshop: job cards, MOT reminders, invoicing and customer records. The listing shows your Northampton garage name, details and website. Leads and exclusivity are never promised ahead of approval and activation.
